2. Description of the Related Art
Air conditioning devices are often used to reduce indoor temperature in the day time or in summer or used to reduce temperature of a refrigerator. They are also used to raise indoor temperature at night or in winter or used to raise temperature of a dryer. To supply cool air or warm air for temperature regulation, the air conditioning devices may consume large electrical energy.
Since the air conditioning devices consumes large energy and the refrigerant used in the air conditioning devices may pollute environment, an energy storable air conditioning device is desired. Such an energy storable air conditioning device may include a seat and an energy storage unit. The seat has a first air entrance and a second air entrance, and a first fan and a second fan are disposed in the first air entrance and the second air entrance respectively. The energy storage unit disposed in the seat has energy storage material in which energy is stored or released as latent heat during phase change. After the air conditioning device is turned off, the energy storage unit continues to provide cooling or heating effect.
However, since the positions of the fan and the energy storage unit are fixed, the fan and the energy storage unit cannot be moved to change the configuration arbitrarily, and the number of the fan and the energy storage unit, which related to the efficiency of the air conditioning device, cannot be changed either. In addition, when some of the energy storage unit fails, which cause reduction of the cooling or heating ability, it is inconvenient to replace them.

The first drawer 21 is connected to the second drawer 31 and air flows from the first drawer 21 to the second drawer 31 by passing the meshed or porous structure 211 and the meshed or porous structure 311. The energy storage unit 32 includes several energy storage elements 321. Each energy storage elements 321 is filled with phase change material. The phase change material includes salt-like phase change material or ozocerite-like material. The phase change material can be flake-shaped, spherical or triangular to increase air contact area.
The energy storable air conditioning device of the invention further includes an air intake module 4. The air intake module 4 includes a third drawer 41 inserted into another one of the receiving space 112 and a filtering unit 42 disposed in the third drawer 41. The bottom of the third drawer 41 has a meshed or porous structure 411 corresponding to the air inlet 12. The first drawer 21, the second drawer 31 and the third drawer 41 are connected to each other so that air flow passes through the first drawer 21, the second drawer 31 and the third drawer 41. Although the meshed or porous structure 411 is disposed on the bottom side of the third drawer 41 for the air inlet 12 in FIGS. 1 to 5, it is not limited thereto. The meshed or porous structure 411 can be disposed in other positions according to requirement.
The energy storable air conditioning device of the invention further includes a seat 5 disposed on the bottom side of the main body 1. The seat 5 has several feet or wheels to keep the seat 5 away from the ground for a distance and move the energy storable air conditioning device easily.

Referring to FIG. 4, the energy unit 3 includes a cool-storage unit having material with melting point ranged 5° C. ̃26° C. and a heat-storage unit having material with melting point ranged 30° C. ̃68° C. The cool-storage unit is pre-cooled at off-peak time (at night) and used for cooling when necessity. When the cool-storage unit is used for cooling, air flows into the first drawer 21 via the air inlet 12 by means of the fan 22. Since the air from outside has a temperature higher than the melting point of the cool-storage unit, the cool-storage unit absorbs heat of air and melts. The air, therefore, flowing form the air outlet 13 has a reduced temperature to cool a refrigerator or an indoor environment. Similarly, the heat-storage unit is pre-heated at off-peak time (at night) and used for heating when necessity. When the heat-storage unit is used for heating, air flows into the first drawer 21 via the air inlet 12 by means of the fan 22. Since the air from outside has a temperature lower than the melting point of the heat-storage unit, the heat-storage unit release heat to air and solidifies. The air, therefore, flowing form the air outlet 13 has a raised temperature to heat an indoor environment. Since the phase change material has a large heat capacity, it is maintained at the melting point to provide cooling or heating function continuously for a long time so as to save energy.
The energy storable air conditioning device of the invention includes an air intake module 4 filtering air through the air inlet 12 to provide better air quality. The energy storable air conditioning device of the invention further includes a seat 5 supporting the main body 1 and keeping the main body 1 from the ground for a distance to facilitate air entrance to the main body 1 via the air inlet 12. The cover 6 has an air guide slot 61 guiding air flow to a desired position.
As shown in FIG. 5, the energy storage module 3 is disposed in the second drawer 31, and the fan 22 is disposed in the first drawer 21. The air blower module 22 and energy storage module 3 are modularized to facilitate expansion and replacement.
