Abstract

The refrigeration unit consists of an evaporator (34), a compressor (32), a condenser (33), a heat exchanger (35), an expansion valve (36) and a suction device (38) for taking the oiled refrigerant vapor from the unit. The heat exchanger (35) enters the compressor (32) when the refrigerant vapor entering the evaporator (34) passes through the suction device (38) in the direction towards the compressor (32).

Claims (4)

1.The cooling unit consists of an evaporator, including a frame, which is designated with an internal cavity. Which has been divided into a liquid chamber for storing liquid refrigerants And the vapor chamber is located above and in the said liquid chamber. With contact with fluid And a first pipe assembly is located in the said fluid chamber. As a way to pass the heat. Which supplies heat to the liquid refrigerant To vaporize the liquid refrigerant part The frame has a bottom exit, at the bottom and in the liquid chamber. Where there is contact with the compressor fluid for the refrigerant vapor from the said evaporator And for converting refrigerant vapor into high pressure refrigerant vapor condenser For high pressure refrigerant vapor from the said compressor And for converting high pressure refrigerant vapor to high pressure liquid refrigerant. Heat exchanger That transfers heat from high pressure liquid refrigerant Entering from the aforementioned condenser to the oil-rich liquid refrigerant Incoming from the liquid chamber at the bottom exit of the said frame. And where the oil-rich liquid refrigerant is converted to oil-rich refrigerant vapor, the expansion valve for the high-pressure liquid refrigerant from the aforementioned heat exchanger. And for replacing high pressure liquid refrigerant to low pressure liquid refrigerant. Which is then released into the liquid chamber One such suction device at the end of the evaporator. And the connection between the said vapor chamber Such compactor And such heat exchanger In order to introduce the oil-rich refrigerant vapor from the heat exchanger into the compressor. When the refrigerant vapor entering the compressed vapor chamber passes through the suction apparatus in one direction towards the compressor. 2. The refrigeration unit of claim 1 also consists of A circulating circuit with two opposite ends connected to the bottom of the frame. And in a liquid room with fluid contact And a second suction device is placed between the opposite side of the said recirculation circuit. And connected to the expansion valve In order to bring liquid refrigerant from the said liquid chamber At one end of the opposite end of the cycle it is returned to the said fluid chamber. At the other end of the opposite end of the cycle When the low pressure liquid refrigerant enters from the expansion valve Through the second device suction device 3. Refrigeration unit of claim No. 1 where such evaporator It also contains a second set of hose assemblies, which are located in the vapor chamber. And has an entrance to the heat exchanger. In order to receive the high pressure liquid refrigerant from the said heat exchanger. And the outlet is connected to the expansion valve In order to release the high pressure liquid refrigerant to the expansion valve. 4. Refrigeration unit of claim No. 2, where such evaporator It also contains a second set of hose assemblies, which are located in the vapor chamber. And has an entrance to the heat exchanger. In order to receive the high pressure liquid refrigerant from the said heat exchanger. And the outlet is connected to the expansion valve In order to release the high pressure liquid refrigerant to the expansion valve.
