Detailed Description
The technical scheme of the utility model is further described with the attached drawings:
the utility model provides a refrigerating system compressor self-cooling device, includes evaporimeter 6, be filled with freon in the evaporimeter 6, evaporimeter 6 is connected with compressor 1's induction port, compressor 1's the other end is connected with the air inlet of condenser 2, the delivery port and the liquid reserve tank 3 of condenser 2 are connected, connect drier-filter 4 behind the liquid reserve tank, connect thermal expansion valve 5 behind drier-filter 4, another termination evaporimeter 6 of thermal expansion valve 5.
In this embodiment, a pressure controller 9 is preferably disposed between the condenser 2 and the liquid storage tank 3.
In this embodiment, preferably, a water outlet of the condenser 2 is connected to a suction port of the compressor 1, and an electromagnetic valve 7 and a throttle pipe 8 are sequentially disposed between the water outlet of the condenser 2 and the suction port of the compressor 1.
In this embodiment, the throttle 8 is preferably a capillary tube.
In this embodiment, the evaporator 6 is preferably a circulation type evaporator.
In this embodiment, the dryer of the drying filter 4 is preferably a molecular sieve.
The compressor 1 sucks low-temperature low-pressure Freon gas from the evaporator 6, the gas with high temperature and high pressure after being compressed enters the condenser, the condenser 2 cools the Freon gas into high-pressure and medium-temperature liquid through heat dissipation, the liquid enters the liquid storage tank 3, the liquid Freon enters the drying filter 4 and then is throttled and decompressed through the thermal expansion valve 5, the liquid Freon after being decompressed enters the evaporator 6 to be vaporized and absorb heat, the temperature of a medium is reduced, the refrigeration purpose is achieved, when the heat dissipation of the condenser 2 is limited, the pressure can be increased after being condensed, the exhaust temperature is increased along with the pressure, when the pressure reaches the set temperature of the pressure controller 9, the electromagnetic valve 7 is started, the high-temperature liquid Freon is throttled through the capillary tube 8 and then directly enters the air suction port of the compressor 1 to be vaporized and absorbed heat, the motor in the compressor is cooled and the suction temperature is, causing compressor failure.
Finally, it should be noted that:
the skilled person can, with reference to the present disclosure, carry out the method and carry out its application, it being expressly noted that all similar substitutes and modifications apparent to the skilled person are deemed to be included within the present invention. The method and application of the present invention have been described in terms of preferred embodiments, and it will be apparent to those skilled in the art that the techniques of the present invention may be practiced and used without departing from the spirit and scope of the present invention by modifying or otherwise appropriately changing or combining the various methods and applications of the present invention.
