Technology Area:
This invention is related to a cassette type refrigeration unit as a separate unit from the refrigerators known as commercial type coolers and from the cabinets used for freezers as to store the products within.
State of the Art:
The portable unit in the refrigerators and freezers, which may be separated from the cooler cabinets, has a cooling case as cassette type. The case type refrigeration unit, termed as cassette, has the facilities that perform the cooling function of the cooler cabinet.
A cassette type refrigeration unit consists of lower cover, upper cover, condenser, evaporator, compressor, evaporator separation Styrofoam, draining pipe, draining pan. Evaporator separator Styrofoam of the unit prevents the temperature loss while the cold temperature provided by cooling cycle circulates within the cabinet via evaporator. There is a seal on the closing, to the cabinet, surface of the cassette type refrigeration unit which prevents the leakage. On the surface which includes such seal there exists two air pockets. These pockets on the closing, to the cabinet, surface of the cassette type refrigeration unit direct the cold air only into the cabinet as isolated thanks to the side seals and evaporator Styrofoam; and the air circulating in the cabinet decreases the cold temperature while returning to the evaporator area, passes over evaporator and is directed into the cabinet as cooled again. The fan in front of the evaporator and on the evaporator Styrofoam passes the air coming from the cabinet over evaporator and redirects it again into the cabinet. The passing of the air through the evaporator in the cassette, for such designed cassette type refrigeration units, is as open slit; that is to say there is no regularly designed air channel. This non-regular air channel may not direct all the circulating air to the evaporator and causes inefficiency. The external body of the existing cassette type refrigeration units consists of thermoform, plastic injection and/or metal sheet and the evaporator Styrofoam within the external body is made of EPS. EPS is an insulation materials which is breakable, inflexible and that easily breaks up due to its weakness. Thus, it has been placed in the external body as away from the impacts. The protection of the EPS material and all the cooling cycle, sealing placement on the upper surface closing to the cabinet and an external body, to be used instead of draining pan, consisting of an upper and lower plastic or metal sheet has been accomplished. The external body consists of at least two pieces and fixed by screws.
The fans in the existing cassette type refrigeration units, used over the evaporator and condenser, are axial fans. These axial fans are circular type and provide air flow on an area as big as the fan diameter. Thus, there exists certain dead zones, on the evaporator and condenser, without any air flow. These dead zones cause inefficiency in the evaporator and condenser.
The internal structures and materials of the existing cassette type refrigeration units differ from each other. The interrelated distances and positions of the fan, condenser, evaporator and compressor of a cooling cycle are important factors that affect the cooling cycle. Different positioning are supported with special mechanical designs and accordingly high cooling cycle performances are provided. The condenser is placed to the side of the cassette in the existing cassette type refrigeration units and the fan is placed at the back of this condenser. The fan behind the condenser pulls the air from the front of the condenser, i.e. external atmosphere, towards the condenser and accordingly causes the environment air to directly contact with the condenser. This causes the accumulation of dust on the condenser.
In the modular refrigeration system under Patent Nr. US5417081, the insulation material for the evaporator zone within the unit exists only in the evaporator zone and this causes temperature loss. Since the axial fan in the evaporator zone does not enable the passing of the air from the entire surface of the evaporator, the performance of the same comes low; no air channels are present in such system.
In the modular refrigeration system under Patent Nr. EP 1547492, the insulation material for the evaporator zone within the unit exists only in the evaporator zone and this causes temperature loss. Since the axial fan in the evaporator zone does not enable the passing of the air from the entire surface of the evaporator, the performance of the same comes low.
The refrigerator under the Patent Nr. US5765388, cross flow fan has been used however its cooling system is not modular.
The modular refrigerating system under Patent Nr. EP 1371922 has been designed as to be placed on the ceiling section of the cabinet. It generates difficulties, during servicing, to carry the approximately 40 kg. refrigerating unit onto the cabinet. The insulation material for the evaporator zone within the unit exists only in the evaporator zone and this causes temperature loss. Since the axial fan in the evaporator zone does not enable the passing of the air from the entire surface of the evaporator, the performance of the same comes low.
The present invention is a cassette type refrigerating/cooling unit which overcomes the aforementioned difficulties; particularly, the sizes of its condenser and evaporator, of which its all surfaces provide efficiency, has been brought to smaller sizes with respect to the desired performance. Since the gas and waste gas of the evaporator and condenser with smaller size also lessened, energy saving and environmental friendliness has been accomplished.
The external body of the invention uses evaporator Styrofoam from EPP (Expandable Polypropylene) which is highly resistant and endurable against impacts. Evaporator Styrofoam and condenser Styrofoam also function as the external body of the cassette type of refrigeration unit. EPP material insulates the compressor sound 50% as well providing temperature insulation. Thanks to the strength and extra insulation features of the EPP (Expandable Polypropylene) material, evaporator and condenser air channels are formed in the interior and high sound and temperature insulation on the exterior also with impact resistance. Moreover, thanks to the strength of the EPP (Expandable Polypropylene) material, an extra external dressing, which is required for other refrigeration units, is not required as condenser and evaporator Styrofoam function as external body.
Cross flow fan and condenser evaporator sizes have been brought to same length size and the wings on the cross flow fan have provided a stronger air flow.
Thanks to the air channels formed in the condenser and evaporator Styrofoam, the air coming from the fan has been passed over the condenser and evaporator in maximum level. The cooled air in the cabinet is sent regularly and in a fast manner to the all surfaces of the evaporator and the suction air from the cabinet is returned on the evaporator again regularly and in a fast manner by forming an evaporator air channel. The evaporator Styrofoam and condenser Styrofoam have been screwed to each other with insert materials providing high level of assembly and disassembly ease.

Detailed Explanation of the Invention
The sides of the lower metal sheet (2), which carries the invention, are bent. These bended sides fix the condenser Styrofoam (3). There are wheels (20) under the lower metal sheet (2) which ease the placement of the invention into the cabinet (2). Evaporation container (18), compressor (17) and EPP condenser Styrofoam (3), which are the parts of the refrigeration system, are placed and fixed on the lower sheet (2). The condenser Styrofoam (3) has a structure which permits the placement of condenser (14) and cross flow fan (5) on it in the frontal zone where compressor (17) and evaporation container (18) on the lower sheet (2) in the backward zone. The evaporator container (18) placed as to meet the condensation arriving from the evaporator (15). The air sent on the condenser (14) by the cross flow fan (5) passes through the condenser (14) and enters in the compressor (17), thus, the temperature of the compressor (17) also decreases.
The length of the cross flow fan (5) on the condenser Styrofoam (3) is same with the length of the condenser (14). The panels on the cross flow fan (5) provide a stronger air transfer. A condenser air channel (24) has been formed on the condenser Styrofoam (3) as to increase the performance of the cross flow fan (5) and to transfer the air all through the condenser (14). The inserts (22), which provide assembly with the condenser Styrofoam (3) on the sides of the EPP evaporator Styrofoam (4) that matches over and assembled to the condenser Styrofoam (3), then lock the two pieces (3,4) to each other.
The arc (26) in the lower part of the frontal zone of evaporator Styrofoam (4) completes the condenser air channel (24). Evaporator Styrofoam (4) has a structure to circulate the cold air in the cabinet through/over the evaporator (15). The surface through which the invention comes close (closes) towards the cabinet (25) is the upper part of evaporator Styrofoam (4). There are cross flow fan (5), evaporator (15) and evaporator upper cover Styrofoam (16) and seal (19) on the evaporator Styrofoam (4). In the frontal zone of the evaporator Styrofoam (4), i.e. in the area where the cross flow fan (5) is placed, an evaporator air channel (23) is formed to ensure the re-circulation of the air in the cabinet (25) by the cross flow fan (5) into the cabinet (25) with high performance and over through evaporator (15). The evaporator air channel (23) is completed with the evaporator Styrofoam (4) on the evaporator (15).
