Accompanying drawing explanation
Figure 1 shows that the structural representation of the ammonia refrigerating installation of a kind of small-sized anti-leak independent operating of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The structural representation of the ammonia refrigerating installation of the small-sized anti-leak independent operating of the present invention as shown in Figure 1, comprises compressor 7, condenser 13, throttling arrangement 14, evaporimeter 4, freezing liquid storage box 3, cooling fluid storage box 12, air-cooler 2, cooler 9, return-air double-tube heat exchanger 5, ventilation sleeve heat exchange of heat pipe 8, freezing liquid circulating pump 15 and coolant recirculation pump 11.Described compressor 7, condenser 13, throttling arrangement 14 and evaporimeter 4 connect to form the circulation of closed ammonia refrigeration successively.Described evaporimeter 4 is placed in freezing liquid storage box 3, and described condenser 13 is placed in cooling fluid storage box 12.The outlet of described freezing liquid storage box 3 is connected by the import of freezing liquid circulating pump 15 with described air-cooler 2, and the outlet of described air-cooler 2 is connected with the import of described freezing liquid storage box 3 by described return-air double-tube heat exchanger 5.The outlet of described cooling fluid storage box 12 is connected with the import of described cooler 9 by described spool piece heat exchanger 8, and described cooler 9 is exported and is connected with the import of described cooling fluid storage box 12 by described coolant recirculation pump 11.Blast pipe between described compressor 7 and condenser 13 is placed in described spool piece heat exchanger 8, and the muffler 6 between described compressor 7 and evaporimeter 4 is placed in described return-air double-tube heat exchanger 5.
In order to avoid using valve to cause leakage, described throttling arrangement 14 is capillary.
The ammonia refrigerant steam entering compressor 7 from muffler 6 enters into condenser 13 and to be cooled liquid heat absorption after compressor 7 compresses, become the ammonia liquid of HTHP, the ammonia liquid of HTHP becomes the ammonia of low-temp low-pressure gas-liquid mixture through capillary 14 becomes gas at the heat of evaporimeter 4 absorption refrigerating liquid and gets back to compressor 7, so circulates.
