Self-contained air-conditioned enclosure

## Abstract

A Self-Contained Air-Conditioned Enclosure; comprises of an Enclosure (1), connected through plurality of openings (13,14) to air ducts (20,21) of an Air-conditioning Unit (17). The Enclosure has a Roof (5), and sidewalls assembled with plurality of Wall Sheets (8) interspaced with Spacer Strips (9) to enhance thermal resistance of the sidewalls. The bottom of the sidewall is inserted under the structure that forms the floor to create an isolated enclosure. The Air-conditioning Unit (17) supplies the Enclosure through the Supply Air Duct (21) and withdraws air through Exit Air Duct (20). Part of the withdrawn air is reconditioned and supplied to the enclosure; the other part is replaced by fresh air. Energy is conserved from the replaced air in Heat Transfer Duct (37) and transferred to fresh air in Fresh Air Chamber (36). Unit efficiency is improved by mixing the exhausted withdrawn air in the Compressor Chamber (31) and exhausted by the Exhaust Air Duct (28). Flow of fresh air is controlled through the Air Damper (39) and Control Knob (38).

BACKGROUND
1. Field of the Invention
This Invention relates to as comfort Air-conditioning, specifically to an air-condition apparatus to provide an air-conditioned enclosure for indoor or outdoor use that is compact and portable.
2. Description of Prior Art
Air-conditioning of space with units employing refrigerants are used for cooling space for personal comfort. Commercial air-conditioners have the following disadvantages:
(a) Higher Capital investment in the space to be air-conditioned: For effective and efficient use of Air-conditioning requires a room or a building to be built with thermal insulation, air infiltration seals, shaded windows and other special requirements. Such special requirements result in higher capital investment in addition to the cost of the air-conditioner.
(b) Higher Capital investment for larger air-condition unit: The minimum space that could be effectively air-conditioned using the traditional air-condition unit is an entire room, even if conditioning is required only for a portion of the room that is occupied. Commercial portable air-conditioners have the same limitation. The larger the space to be air-conditioned the larger is the air-condition unit required. Larger the unit higher the cost. For example in a bedroom, the minimum space that requires air-conditioning is the compact space surrounding the body of the occupants. In current application, the entire bedroom needs to be air-conditioned. This will result in unnecessary extra cost of larger equipment and installation.
(c) Higher Operation cost: As discussed in previous paragraphs traditional units would be of larger capacity than the minimum needed for specific applications. Larger the unit higher is the operating cost for electric energy. Cooling of a selective smaller space offers comfort at a lower operational cost. A selected enclosure could be cooled with commercially available portable air-conditioner however the disadvantage is the portable air-conditioner can not supply cooled fresh air but only re-circulates the space air.
(d) Enclosures available for clean air requirements such as Michael H. Pelosi, III et al U.S. Pat. No. 5,314,377 is not suitable for comfort Air-conditioning of a compact space, as it requires an independent source of conditioned air in the place of the clean air source. In addition, the prior art enclosure has cumbersome structure requiring complex assembly. The objective of that enclosure is to provide clean air and not comfort conditioning, so major modification is necessary before it can be used for comfort air-condition application.
Commercially available portable air-conditioner can cool an enclosed space however the disadvantage is it cannot supply cooled fresh air but can only re-circulates the space air. Thus, none of the current apparatuses is suitable for providing an air-conditioned enclosure.
Air-conditioned Mosquito net of patents such as San Jianhua et al China. Pat. No. CN2259099 and Tan Mingsen et al China. Pat. No. CN1163735 illustrates mosquito nets connected to a conditioned air source by an air duct. Both of these prior art requires an external source of conditioned air. In addition, in both of these prior arts, outside air is conditioned and supplied to the enclosure and all of the air is exhausted outside the enclosure. ‘Heat Insulating Mosquito-Net’ of He Baoan et al China. Pat. No. CN1061140 illustrates a mosquito net with plurality of inflatable air-pocket walls. This art has the disadvantage of requiring inflation of wall air pockets and increases the chance of failure of thermal insulation due to puncturing of the air pockets. cl SUMMARY

        (e) to provide cooled or heated fresh air to offer better air quality for the occupants;
        (f) to provide energy conservation by pre-cooling the fresh inlet air with the cool exhaust air. The same applies for heating too;
        (g) to provide control over the quantity of fresh air using air damper;
        (h) to improve the efficiency of the system by using the exhaust air for the condenser coil cooling;
        (i) to provide an air-conditioned personal space for both indoor and outdoors use;
        (j) to provide reduced initial cooling time from the start of cooling to achieve the comfort temperature. The same applies for heating too;
        (k) to provide comfort air-conditioning without requiring special building construction requirements such as thermal insulation, air infiltration seals, shaded windows and others;
        (l) to provide an enclosure for quick assembly using widely available materials;
        (m) to provide a dedicated Air-conditioning Unit to provide comfort in the enclosed space

The Enclosure may have one of several shapes such as rectangle, square, cylindrical or a combination thereof.
Various types of air-condition may be generally referred to but the invention is particularly adapted to a process of heating or cooling, humidification or dehumidification and filtering of air only.
The invention comprising of an Enclosure and an air-condition unit can be fitted on to any flat surface. In the embodiment described, the frame of the Enclosure is structurally fitted onto the floor surface and the wall sheets tucked at the floor level under the structure that forms the floor. This forms a good airtight Enclosure, which is thermally isolated.
The one sidewall of the Enclosure has two openings with elastic rims to accommodate air ducts i.e. exit air duct and supply air duct of the Air-conditioning Unit.
The Air-conditioning Unit has the traditional parts such as compressor, evaporator coil, condenser coil, air filter, fans, motor, controls and others assembled as described in the preferred embodiment to supply fresh air and re-circulated cool air to the said Enclosure of the preferred embodiment.
The present invention provides a portable airtight Enclosure system with openings for receiving the Air-conditioning ducts and an Air-conditioning Unit for providing a suitable clean, cool and conditioned atmosphere, within the said Enclosure system. The Enclosure system can assume various shapes suitably in accordance with the shape of the frame, which is the structural support for the said Enclosure. In the preferred embodiment of the present invention, there is provided a rectangular system comprising a hard board roof with soft sheet walls thus ensuring insulation on all sides.
In accordance with the present invention there is provided a method for providing a suitably conditioned Enclosure which comprises of using an air-conditioner means which comprises the steps of enclosing a volume of air in the Enclosure filtering and conditioning fresh air and supplying the conditioned air to the said Enclosure, and exhausting the air from the Enclosure.
Advantages of this system are that it provides for a simple, portable, economical, enclosure system, which is easy to manufacture and sell and equally easy to assemble and to dismantle when not in use. The Air-conditioning Unit also provides for energy conservation by pre-cooling/pre-heating the fresh inlet air with the cool/hot exhaust air. In addition, the condenser coil cooling is enhanced by using the exhaust air. The present invention as a whole is inexpensive, more compact, more efficient and portable.
Another example of the Enclosure structure similar to the one described herein above is to have the following:
As an extension of scope of invention, a typical example is to have a single pre-fabricated foldable enclosure—comprising of framework including the roof, the sidewall sheets and spacer strips. This is simple to avoid the assembly work involved in the preferred embodiment herein above described in the previous paragraphs.
The Enclosure is pre-fabricated with the wall sheets and spacer strips including a roof portion and drapes over the frame structure. One side of the wall may be provided with re-sealable opening for people passage preferably with hook and loop fasteners.
Working of the Invention
The working of the invention is herein described in detail. The said Enclosure assembly 1, creates an isolated air space above an occupied surface, an example of such an application is around a bed as shown in FIG. 1.
The Enclosure isolates the inside space from the outside thermally and avoids outside air infiltration. The said air opening rims 15 and 16, wrap around the said Air Ducts, and offers air passage or connection with the Air-condition Unit 17. The Enclosure assembly is structured to be lightweight, to cost less, and to offer quick and easy assembly and disassembly; thus offering portability.
Enclosure air is drawn through the Exit Air opening 13 and Exit Air Duct 20. Part of the air from Exit Air Duct 20 and Fresh air from Fresh Air Chamber 36 is mixed in the Air Plenum 23. The air is filtered through the Air Filter 25 and is moved by fan 24 through the Evaporator Coil Assembly 26, where it is conditioned. The conditioned air enters the Enclosure through the Supply Air Duct 21.
Part of the Exit air from duct 20 passes through the Heat Transfer Duct 37 to Compressor Chamber 31. The Air Damper 39 controls the flow of air inside the Heat Transfer Duct 37. Air Damper 39 is adjusted by the Control Knob 38 interconnected by Control Rods and links 40. The air in duct 37, pre-conditions, pre-cools or pre-heats the fresh air in the Fresh Air Chamber 36. This pre-conditioning of the fresh air by the exhaust air conserves energy. The Fresh Air chamber is supplied by fresh air through the Air Grills 33 located at the bottom.
Outside air is also drawn inside the compressor chamber 31, through the air grills at the lower portion of the said Chamber. Air from the Heat Transfer Duct 37, enters the said chamber 31, mixes with air in the chamber, and is moved by the blower 27. The blower moves the air mixture across the condenser coil assembly 30, and exhausts it through the exhaust duct 28. The exhaust duct's free end may be located to exhaust hot air outside of the building through a window or doorway if the invention is used indoor. For outdoor use the exhaust duct can exhaust to the space.
Conclusions Ramifications and Scope
The above description illustrates the Self-contained Air-Conditioned Enclosure provides air-conditioned comfort with fresh air at economical capital cost, conserves energy, operates with lower cost, is portable can be assembled easily and has longer life.
While the above contains many specifications these should not he construed as limitations on the scope of the scope of the invention, but rater as an exemplification of one preferred embodiment thereof. Many other variations are possible a few examples follow.
The rigid Enclosure Roof of the enclosure can replaced with an assembly similar to the sidewalls, with Wall Sheets and Spacer Strips. The Enclosure Frame structure instead of located outside the enclosure could be placed inside and support the enclosure. The Enclosure can be colored and have other shapes such as circular, square or combination thereof. The Enclosure sidewall can have slit opening for entry or exit to the Enclosure that can be sealed and fastened by hook-and-loop fasteners etc.
The components of the Air-condition Unit can be rearranged to serve the same purpose as this invention. The Air moving devises can be connected with a longer shaft driven by a single electric motor. The air-conditioner or its control can be modified to work as a heat pump. The Unit size can be compacted by eliminating the Fresh Air Chamber and Heat transfer duct at the expense of energy conservation.
Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
