The present invention relates to an air conditioning module, and more particularly, to an air conditioning module, which can perform cooling and heating through a single module, which is capable of being compact-sized, which can easily control a flow of heated or cooled air, which can disperse weight because a compressor is mounted in a first space and the other components are mounted in a second space, and which is easy in carrying due to a handle.

BACKGROUND ART

An air conditioner for a vehicle is a car part, which is installed in a vehicle for the purpose of cooling or heating the interior of the vehicle in the summer season or the winter season or removing frost from a windshield in the rainy season or the winter season to thereby secure a driver's front and rear visual fields. Such an air conditioner typically includes a heating device and a cooling device together, so that it can heat, cool or ventilate the interior of the vehicle through the steps of selectively introducing the inside air or the outside air into the air conditioner, heating or cooling the introduced air, and blowing the heated or cooled air into the vehicle.

FIG. 1is a schematic diagram showing an example of a conventional air conditioner for a vehicle. The conventional air conditioner for the vehicle includes: an air-conditioning case10which has vents11,12and13adjusted in the degree of opening by doors11d,12dand13d; a blowing part14connected to an inlet of the air-conditioning case10to blow outside air; an evaporator E and a heater core H disposed inside the air-conditioning case10; and a temp door15for adjusting the degree of opening of a cooled air passageway and a heated air passageway of the air-conditioning case10. When a cooling cycle is operated, the temp door15opens the cooled air passageway and closes the heated air passageway. Therefore, the air blown by the blowing part14exchanges heat with refrigerant flowing inside the evaporator E and is changed into cooled air while passing through the evaporator E, and then, is discharged to the interior of the vehicle through the opened vents11,12and13so as to cool the interior of the vehicle. Moreover, when a heating cycle is operated, the temp door15closes the cooled air passageway and opens the heated air passageway, the blown air exchanges heat with cooling water flowing inside the heater core H while passing the heater core H through the heated air passageway and is changed into heated air, and then, is discharged to the interior of the vehicle through the vents11,12and13so as to warm the interior of the vehicle.

In this instance, in order to supply cold refrigerant to the first evaporator, as shown inFIG. 2, a compressor1which compresses and sends refrigerant, a condenser2which condenses the refrigerant of high pressure sent from the compressor1, an expansion valve3for throttling the refrigerant condensed and liquefied in the condenser2; an evaporator E for exchanging heat between the liquefied refrigerant of low pressure throttled by the expansion valve3and evaporating the refrigerant to cool the air discharged to the interior of the vehicle due to heat absorption by evaporative latent heat; and refrigerant pipes5through which the compressor1, the condenser2, the expansion valve3and the evaporator E are connected with one another. In the meantime, as described above, the evaporator E is disposed inside the air-conditioning case10, the condenser2is located at the front of the vehicle in order to cool the refrigerant using traveling wind, and the compressor1is located inside an engine room because it is operated by an engine actuating belt. Therefore, the conventional air-conditioning system has a disadvantage in that connection of the pipes5becomes complicated.

In the meantime, in order to cool the interior of a vehicle, such as a truck, even in a state where the engine is not operated, an anti-start air-conditioner for a vehicle operated by a battery as a power source has been proposed. Such an anti-start air-conditioner for a vehicle is illustrated inFIGS. 3 and 4.FIG. 3is a perspective view of the anti-start air-conditioner for the vehicle, andFIG. 4is a schematic diagram of the anti-start air-conditioner for the vehicle. The anti-start air-conditioner for the vehicle includes: first and second compressors10aand10boperated by the battery for the vehicle as a power source; a lying-type condenser20including first and second condensing parts20aand20b, which are respectively communicated with the first and second compressors10aand10band have condenser inlets21to which refrigerant is induced and condenser outlets22through which the induced refrigerant is discharged after exchanging heat with outside air; first and second capillary tubes30aand30bwhich are respectively communicated with the condenser outlets22formed in the first and second condensing parts20aand20b; and first and second evaporators40aand40bwhich are respectively communicated with the first and second capillary tubes30aand30band have first evaporator inlets41to which refrigerant is induced and first evaporator outlets42through which the induced refrigerant is discharged to the first and second compressors10aand10bafter exchanging heat with the inside air.

However, the conventional air-conditioning system for the vehicle uses engine cooling water in order to perform heating, and the anti-start air-conditioner for the vehicle must have a heater mounted to heat the interior of the vehicle even in the state where the engine is not operated.

Therefore, an apparatus, which can perform heating and cooling at the same time, has a compact size and is easily installed in a vehicle is demanded, and especially, an apparatus which can properly perform heating and cooling even in the state where the engine is stopped or is not in use is demanded.

The air conditioning module1000according to the embodiment of the present invention includes a compressor100, a condenser200, an expansion valve300, an evaporator400, a first blowing part510, a first door610, a second blowing part520, a second door620, and a housing800.

The compressor100is to inhale and compress gas-phase refrigerant, and supplies the gas-phase refrigerant of high-temperature and high-pressure to the condenser200. In this instance, the compressor100is operated by receiving a driving force by a power supply unit and a battery mounted inside the vehicle or an external power supply.

The condenser200condenses the gas-phase refrigerant into liquid of high-temperature and high-pressure by exchanging heat between the gas-phase refrigerant of high-temperature and high-pressure discharged from the compressor100and outside air, and then, discharges the liquid of high-temperature and high-pressure to the expansion valve300. In this instance, the condenser200acts as a heating source for heating air passing through the condenser200when the refrigerant is condensed.

As shown inFIG. 6, the condenser200includes: a pair of header tanks210spaced apart from each other at a predetermined interval and disposed side by side to form a refrigerant passageway; a tube220of which both ends are fixed to the header tanks210; a pin230interposed in the tube220; and a gas-liquid separator240connected to the header tanks210to separate liquid-phase refrigerant from gas-phase refrigerant. In this instance, the gas-liquid separator240is located to be perpendicular to the direction that the header tanks210, the tube220and the pin230are formed, is disposed on a first discharge passageway830or a second discharge passageway840of one side so as to maximize the formation area of the header tanks210, the tube220and the pin230. Moreover, preferably, the air conditioning module may be compact-sized and sufficiently secure an area to exchange heat with air because the blowing part510may be located near to the formation area of the header tanks210, the tube220and the pin230.

In this instance, the gas-liquid separator240may include a body241having a desiccating agent therein and a refrigerant filling port242formed at one side of the body241so as to facilitate replenishment of refrigerant in the state where the condenser200is mounted. The housing800related with the above will be described later.

The expansion valve300rapidly expands the liquid-phase refrigerant of high-temperature and high-pressure discharged from the condenser200by a throttling action to make it into a wet saturated state of low-temperature and low-pressure, and discharges it to the evaporator400.

The evaporator400exchanges heat between outside air and the liquid-phase refrigerant of low-pressure throttled in the expansion valve300to vaporize the refrigerant, and then, discharges it to the compressor100. In this instance, the condenser200acts as a cooling source to cool the air passing through the evaporator400when the refrigerant is vaporized. InFIG. 6, the evaporator400includes a pair of header tanks410, a tube420of which both ends are fixed to the header tanks410, and a pin430interposed in the tube420.

In other words, the refrigerant circulates the compressor100, the condenser200, the expansion valve300and the evaporator400in order, and the compressor100, the condenser200, the expansion valve300and the evaporator400are connected with one another through pipes (not shown).

The first blowing part510is means for blowing air so that the air is heated after passing through the condenser200, and the second blowing part520is means for blowing air so that the air is cooled after passing through the evaporator400. The first blowing part510and the second blowing part520may adopt a cross flow fan type. In addition, the blowing parts510and520may adopt one of various types that can blow air to the condenser200and the evaporator400.

The first door610regulates a flow of the air blown by the first blowing part510, and transfers the air heated through the condenser200to the interior of the vehicle or discharges the heated air to the outside. Moreover, the second door620regulates a flow of the air blown by the second blowing part520, and transfers the air cooled through the evaporator400to the interior of the vehicle or discharges the cooled air to the outside. In this instance, the first door610and the second door620may adopt one of various forms, and especially, the first door610includes a first rotary shaft611and a plate part612extending from the first rotary shaft611, and the second door620includes a second rotary shaft621, a pair of support part622vertically extending in the form of a fan shape of which the center is connected with the second rotary shaft621, and a closed part623for connecting the outer peripheries of the support parts622with each other. That is, the first door610is opened such that the air flows by the plate part612to be supplied to the interior of the vehicle, or is closed such that the air is discharged to the outside. The second door620is opened such that the air flows by the closed part623to be supplied to the interior of the vehicle, or is closed such that the air is discharged to the outside.

Out of the components of the air conditioning module1000, except the housing800, the compressor100is the heaviest. So, the compressor100is arranged at one side in the longitudinal direction, and the condenser200, the evaporator400, the first blowing part510and the second blowing part520are arranged at the other side. Particularly, the housing800is divided into a first space801and a second space802in the longitudinal direction, and the components of the air conditioning module1000are mounted inside the housing800. In this instance, the first space801is an area where the compressor100is disposed, and the second space802is an area where the rest components except the compressor100, namely, the condenser200, the expansion means300, the evaporator400, the first blowing part510, the first door610, the second blowing part520and the second door620, are disposed. In other words, the second space802is a space for transferring or discharging the air supplied through the first blowing part510and the second blowing part520to the interior of the vehicle by actuation of the first door610and the second door620. Therefore, the air conditioning module1000according to the embodiment of the present invention keeps balance of weight in the longitudinal direction.

Moreover, the housing800includes a handle800dsuch that a user can carry the air conditioning module1000. The handle800dis disposed at the upper side of the housing800and is located in consideration of the center of gravity in the longitudinal direction.

Additionally, preferably, the air conditioning module1000according to the embodiment of the present invention includes a circuit board900, which is disposed in the first space801of the housing800in order to operate the compressor100. In the present invention, the circuit board900means electronic parts having an inverter and others in order to prevent energy loss when the circuit board900gets farther apart from the position of the compressor100. Furthermore, preferably, the circuit board900is located at right angles to the longitudinal direction to minimize a damage by condensate water. That is, the circuit board900is mounted in such a way that the side of the circuit board900is perpendicular to the bottom surface of the housing800.

In order to formed an air flow that air is supplied to the interior of the vehicle or discharged to the outside after being induced into the housing800and heated or cooled, in the housing800in which the condenser200, the expansion means300, the evaporator400, the first blowing part510, the first door610, the second blowing part520and the second door620are mounted, a first inflow part811and a second inflow part812are formed to be hollow, and a first passageway821and a second passageway822are formed therein to supply the heated or cooled air to the interior of the vehicle.

The first inflow part811is a hollow area formed at a certain area of the housing800to transfer the air to the condenser200, and the second inflow part812is a hollow area formed at a certain area of the housing800to transfer the air to the evaporator400. InFIGS. 5 to 9, it is illustrated that the first inflow part811is formed on the bottom of the housing800, and the second inflow part812is formed on the side of the housing800(the front side inFIGS. 5 to 7), but the first and second inflow parts811and812may be formed on one of various positions that can transfer the air to the condenser200and the evaporator400.

The first passageway821is formed inside the housing800to form a space that the air passing through the condenser200is transferred to the interior of the vehicle, and the condenser200, the first blowing part510, and the first door610are mounted on the first passageway821. Furthermore, the second passageway822is formed inside the housing800to form a space that the air passing through the evaporator400is transferred to the interior of the vehicle, and the evaporator400, the second blowing part520, and the second door620are mounted on the second passageway822. In this instance, it is preferable that certain areas of the first and second passageways821and822, which discharge air to the interior of the vehicle, be formed to be adjacent to each other in the height direction such that the first passageway821and the second passageway822facilitate designing a flow of air.

Moreover, the housing800includes a first discharge passageway830connected with the first passageway821and a second discharge passageway840connected with the second passageway822to discharge air, which is not supplied to a passenger. The first discharge passageway830is openable and closable by the first door610and is a passageway formed by extending from a first discharge hole831hollowed at a certain area of the first passageway821to discharge air to the outside. Furthermore, the second discharge passageway840is openable and closable by the second door620and is a passageway formed by extending from a second discharge hole832hollowed at a certain area of the second passageway822to discharge air to the outside.

In this instance, the first discharge passageway830and the second discharge passageway840are formed to be adjacent to each other, and are opened toward the bottom surface of the housing800. That is, the first passageway821and the second passageway822for supplying air to the interior of the vehicle are formed at one side of the housing800, and the first discharge passageway830and the second discharge passageway840for discharging air to the outside are opened to the bottom surface of the housing800. Moreover, the first discharge passageway830and the second discharge passageway840are formed to be adjacent to each other. Preferably, the first discharge passageway830is located in the middle in the longitudinal direction of the first door610and the second door620, and the second discharge passageway840is formed at both sides of the first discharge passageway830(See the bottom plan view ofFIG. 10). Therefore, the air conditioning module1000according to the preferred embodiment of the present invention can easily heat and cool the air to supply the heated or cooled air to the interior of the vehicle, and easily discharge unnecessary air to the outside, thereby enhancing cooling and heating comfort and miniaturizing the size of the air conditioning module.

Furthermore, in the housing800, actuating means700for actuating the first door610and the second door620and a certain area of a pipeline (not shown) may be located on the second discharge passageway840where the air cooled after passing through the evaporator400is not supplied to the interior of the vehicle but is discharged. In this instance, the actuating means700is an actuator720, and the pipeline is to connect the compressor100, the condenser200, the expansion means300and the evaporator400and most area of the pipeline is located on the second discharge passageway840. Therefore, the air conditioning module1000according to the preferred embodiment of the present invention can protect the actuating means700and the pipeline, which are located outside the air-conditioning case in the case of conventional air conditioners, because the actuating means700and the pipeline are located inside the housing800, and can be cooled while the air cooled through the evaporator400flows.

Referring toFIG. 11showing a heating state, the first door610opens the first passageway821to transfer the heated air to the interior of the vehicle, and closes the first discharge hole831to close a flow which discharges the heated air to the outside. In this instance, the second door620closes the second passageway822to prevent the cooled air from being transferred to the interior of the vehicle, and opens the second discharge hole832to discharge the cooled air to the outside. InFIG. 11, the flow of the heated air supplied to the interior of the vehicle is indicated by hollow arrows, and a flow of the cooled air discharged to the outside is indicated by black arrows, whereinFIG. 11Ashows the air flow using the sectional view ofFIG. 5taken along the line AA′, in which the first passageway821, the second passageway822and the first discharge passageway830are formed, andFIG. 11Bshows the air flow using the sectional view ofFIG. 5taken along the line BB′, in which the second passageway822and the second discharge passageway840are formed.

On the contrary, referring toFIG. 12showing a cooling state, the second door620opens the second passageway822to transfer the heated air to the interior of the vehicle, and closes the second discharge hole832to close a flow which discharges the cooled air to the outside. In this instance, the first door610closes the first passageway821to prevent the cooled air from being transferred to the interior of the vehicle, and opens the first discharge hole831to discharge the heated air to the outside.

In the meantime, in the air conditioning module1000according to the preferred embodiment of the present invention, the housing800may include a first housing800aand a second housing800b, which are combined at both sides in the longitudinal direction of the compressor100, the condenser200, the expansion means300, the evaporator400, the first blowing part510, the first door610, the second blowing part520, and the second door620. The compressor100is easy in mounting but may generate noise, so may be formed to be openable and closable by a cover800c.

Furthermore, the expansion means300may be embedded in the housing800. As described above, because the refrigerant circulates the compressor100, the condenser200, the expansion valve300and the evaporator400in order, the expansion means300is embedded in the area of the housing800, which partitions the condenser200from the evaporator400, and a pipeline in which the refrigerant discharged from the condenser200flows and a pipeline in which refrigerant is supplied to the evaporator400may be connected to the area where the expansion means300is formed. Particularly, the expansion means300may have an orifice form of which the inner space decreases gradually and increases gradually because the expansion means300corresponds to an area formed in the housing800as the space through which the refrigerant passes (SeeFIG. 8). Therefore, the air conditioning module1000according to the preferred embodiment of the present invention can reduce the number of components and time and costs required for assembly because there is no need to additionally prepare and assemble the expansion means300.

The air conditioning module1000according to the preferred embodiment of the present invention may further include actuating means700, which is connected with the first door610and the second door620to open the first door610and close the second door620or to close the first door610and open the second door620. That is, the actuating means700makes the first door610and the second door620work together. The actuating means700controls in such a way that the second door620is closed when the first door610is opened and the second door620is opened when the first door610is closed.

In an embodiment, the actuating means700includes a link member710for connecting the first door610and the second door620with each other and an actuator720for actuating the link member710. The link member710includes a first door lever711combined with a first rotary shaft611of the first door610, a second door lever712combined with a second rotary shaft621of the second door620, and a connection link713for connecting the first door lever711and the second door lever712with each other. In the case that the first door lever711and the first rotary shaft611connected with the first door lever711are rotated by operation of the actuator720to open the first door610, the second door lever connected through the connection link713and the second rotary shaft621connected with the second door lever are also rotated to close the second door620. Moreover, in the case that the first door lever and the first rotary shaft611connected with the first door lever are rotated by operation of the actuator720to close the first door610, the second door lever connected through the connection link713and the second rotary shaft621connected with the second door lever are also rotated to open the second door620. Therefore, the air conditioning module1000according to the embodiment of the present invention can control the first door610and the second door620to work together by operation of the actuator720, thereby being easy in working.

The air conditioning module1000described above can be used as an apparatus for cooling and heating the interior of the vehicle because performing not only cooling but also heating as a single unit. Additionally, because the air conditioning module1000according to the present invention can be detachably mounted on the vehicle by a passenger, it can be detached from the vehicle and used outside the vehicle if there is a need to adjust temperature outside the vehicle. In the present invention, the “passenger” may be interpreted as a “user”, who uses the air conditioning module1000outside the vehicle, and the direction may be the side that air is discharged through the first passageway821and the second passageway822. During outdoor activities, if air conditioning is needed, the air conditioning module1000according to the present invention may be operated by a battery of the vehicle or an external power supply. Moreover, the air conditioning module1000may be mounted at one of various places from which the air conditioning module1000can be attached and detached. As an example, the air conditioning module1000can be mounted on a glove box, a console box, a space between the rear seat and the rear window, or the floor of the vehicle. The present invention is not restricted to the above, and the air conditioning module1000can be mounted at any place where the air conditioning module1000can be detachably mounted. The air conditioning module1000according to the present invention may be controlled by a main control system of the vehicle, or controlled independently from the main control system. In other words, the air conditioning module1000according to the present invention may be operated independently from the main control system, which controls interior air conditioning of the vehicle, regardless the cases that the air conditioning module performs interior air conditioning of the vehicle or is used outside the vehicle.

The air conditioning module according to the preferred embodiment of the present invention is an apparatus, which may be applied to air conditioners for various vehicles, to heat or cool the interior of the vehicle or to defrost the windshield of the vehicle. So, the air conditioning module is used as a car internal, which offers convenience for a driver.
