Abstract

Apparatus (2) for refrigeration and/or air conditioning comprising a housing (4), at least one compressor (6) in the housing (4), at least one condenser (8) in the housing (4), and a louvre construction (10) on one face (12) of the housing (4), the louvre construction (10) being such as to allow both air inlet (14) and air exhaust (16).

Description

APPARATUS FOR REFRIGERATION AND/OR AIR CONDITIONING This invention relates to apparatus for refrigeration and/or air conditioning.
Known apparatus for refrigeration and/or air conditioning is traditionally bulky. The apparatus often takes up space that is needed for other purposes. In addition, the known apparatus tends to take time to install, is aesthetically poor, is difficult to service, and does not provide a durable installation.
It is an aim of the present invention to obviate or reduce the above mentioned problems.
Accordingly, in one non-limiting embodiment of the present invention there is provided apparatus for refrigeration and/or air conditioning, which apparatus comprises a housing, at least one compressor in the housing, at least one condenser in the housing, and a louvre construction on one face of the housing, the louvre construction being such as to allow both air inlet and air exhaust.
The apparatus of the present invention is space efficient and easy to install. The housing can be constructed to be both aesthetically pleasing and durable. If desired, the housing can be produced to blend into the fabric of a building. The apparatus can be installed inside or outside a building as may be desired.
Preferably, the apparatus is one in which the louvre construction is in a front face of a housing.
The front face of the housing is preferably formed by at least one door. Usually, there will be two of the doors.
The condenser may be a horizontally mounted condenser which is positioned in an upper half of the housing. This enables a significant reduction on dirt build up which might otherwise occur on the condenser, thereby reducing efficiencies and incurring increased maintenance costs.
Embodiments of the invention will Now be described solely by way of example and with reference to the accompanying drawings in which: Figure 1 is a section through first apparatus of the invention; Figure 2 shows how the apparatus of Figure 1 can be installed in comparison with known apparatus; Figure 3 shows four different sizes of apparatus of the invention; and Figure 4 is a perspective view inside one type of apparatus of the invention.
Referring to Figure 1, there is shown apparatus 2 for refrigeration and/or air conditioning. The apparatus 2 comprises a housing 4, a compressor 6 positioned at a bottom part of the housing 4, and a condenser 8 positioned in an upper half of the housing 4. The housing 4 has a louvre construction 10 on a front face 12 of the housing. Louvre construction 10 is such as to allow air inlet as shown by arrow 14 and air outlet as shown by arrow 16. A person 18 is shown in Figure 1 to illustrate the size of the apparatus 2.
Figure 2 shows how the apparatus 2 can be inserted within the width of the wall 20. Because the louvre construction 10 is on the front face 12 of the housing, no air space is required around the back and sides of the housing 4.
Figure 2 also shows how the apparatus 2 can be installed against a front face 22 of the wall 20.
Again no air space is required because the louvre construction 10 is in the front face 12.
Figure 2 also shows how known apparatus 24 would typically be installed. The known apparatus 24 requires an air space 26 for air circulation for the apparatus 24. Still further, the apparatus 24 is much thicker than the apparatus 2. In comparison, the apparatus 2 is streamline apparatus.
Figure 3 shows four different types of apparatus 2 in accordance with the invention. The top part of Figure 3 shows the apparatus 2 from the front whilst the bottom part of Figure 3 shows the apparatus 2 from the side. The measurements given are given by way of example only. The louvre construction 10 will be noted. It will also be noted that whilst the four different types of apparatus 2 increase in size considerably from the front, they are all still quite narrow and streamlined. This facilitates installation in places as shown in Figure 2.
Referring now to Figure 4, there is shown in detail one specific design for the apparatus 2 of the invention. Similar parts as in previous Figures have been given the same reference numerals for ease of comparison and understanding.
The housing 4 is designed to include all refrigeration systems and air conditioning needs. The housing 4 is able to reduce floor space requirement by up to 40% as compared with traditional apparatus employing individual units. The slimline construction of the housing 4 limits the intrusion of the housing 4 into otherwise usuable floor space. The housing 4 will usually be constructed from a metal such for example as steel coated with zinc-based rustproof finish.
The louvre construction 10 prevents recirculation of exhaust air whilst at the same time allowing air inlet and air exhaust. Vermin control features are built into the design. The louvre construction 10 is formed in two doors 26, only one of which is shown so that part of the interior of the housing 4 can be seen > The doors 26 are mounted on hinges 28.
The apparatus 2 is designed to eliminate possible causes of refrigerant leaks, whilst retaining a high degree of serviceability.
The doors 26 are locked by locking T-handles 30.
The handles 30 provide good security whilst also providing easy access for service personnel. The handles 30 and the hinges 28 are constructed from stainless steel but other materials may be employed if desired.
A pressure relief valve 32 is employed. The pressure relief valve 32 will open if excessive pressure develops in a container 34. The pressure relief valve 32 will close as soon as the pressure falls, in order to prevent further refrigerant loss.
Such a pressure relief valve 32 is an advantage over a traditionally used fuseable plug which would result in total loss of the refrigerant.
The condenser 8 is mounted at a high level in the housing 4. This significantly reduces any dirt build up that might otherwise occur and which would reduce efficiency and incur maintenance costs.
The housing 4 contains custom built control panels 36. The control panels 36 eliminate the need for separate internal control systems. This helps to reduce installation costs and installation times. The control panels 36 include a separate distribution panel.
It will be appreciated from the drawings that the apparatus of the present invention is extremely efficient in saving space. It is easy to install.
The achievements of space saving and easy installation are especially significant when they are used for low temperature refrigeration as distinct from air conditioning. The receiver of the apparatus 2 is located in the air inlet stream and is thus cooled by ambient air. This increases overall efficiency of the apparatus 2. The front access to the apparatus 2 via the doors 26 provides for easy access and maintenance.
The apparatus 2 may be made to be of modular construction, for example from 0.75 - 6.00 horse power.
The compressor used in the apparatus 2 may be a semi-hermetic compressor. The compressor may be spring mounted and/or rubber mounted. A discharge line used in the apparatus 2 may be provided with a vibration eliminator. The condenser may be of a copper tube/aluminium fin construction, with a wide fin spacing. A condenser fan motor will usually be employed. Safety switches may be pre-wired complete with flexible stainless steel braided hose connections. The apparatus 2 can be connected together as modules by bolting together the housings.
It is to be appreciated that the embodiments of the invention described above with reference to the accompanying drawings have been given by way of example only and that modifications may be effected.
Thus, for example, the apparatus 2 can be fitted with a stand alone control panel complete with an isolator, power on and trip warning lights. A filter dryer and sight glass of in-line T-flow design may be employed.
An oil separator complete with return line, sight glass and shut off valve may be employed. The apparatus may be provided with crankcase and oil separator heaters, fully wired. Additional pressure control switches may be employed as desired. The apparatus may also be provided with one or more of head pressure control valves, a suction accumulator, adjustable feet, acoustic louvres and lining, a vermin control guard, and a suction and liquid line stub to the exterior.
