Abstract
The utility model discloses an apparatus for testing the service life of a refrigerator compressor, comprising the refrigerator compressor. The high pressure terminals of the refrigerator compressor are communicated with the annular space in the casing tubes of a condensation evaporator through a cut-off valve; the lower ends of the annular space in the casing tubes of the condensation evaporator are communicated with the inlet end of a throttle valve; the outlet end of the throttle valve is communicated with the lower ends of the central tubes of the condensation evaporator of the type of the casing tubes; the upper ends of the central tubes are communicated with the lower pressure terminals of the refrigerator compressor through a suction line valve. The exchange of heat between the hot and cold fluid of a system is fully utilized by the utility model, reducing the consumption of the power of outside electric fans when tested, and achieving the aims of reducing the manufacturing cost of testing apparatus and operating cost.
Description
The utility model relates to a kind of experimental provision, particularly a kind of life experiment device of refrigeration compressor.
Refrigeration compressor life experiment device is the specialized equipment of test refrigeration compressor reliability.Complete refrigeration compressor life test apparatus is the special system of a simulation refrigeration cycle.Usually this system is made up of equipment such as compressor, condenser, throttling valve, evaporator and fans, and wherein condenser is to the extraneous equipment that transmits heat of the circulation system, and evaporator is the equipment to circulation system absorbed inside heat.In the side cold compressor life experiment device that use the home and abroad,, promptly be equipped with independently condenser and evaporator at present, make that the manufacturing of this device and operating cost are higher owing to adopt the design concept identical with common refrigeration plant.
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, proposes a kind of refrigeration compressor life experiment device.This device will need to absorb heat and two equipment of heat release are merged into one, soon condenser, evaporator are merged into condenser/evaporator, thereby made full use of the heat exchange of internal system cold and hot fluid, the consumption of extraneous electric fan power when reducing experiment reaches the purpose that reduces experimental provision manufacturing cost and operating cost.
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is the structure principle chart of snakelike bushing type condenser/evaporator of the present utility model, and wherein (a) is that front elevation, (b) are vertical views.
Fig. 3 is the structure principle chart of spirality bushing type condenser/evaporator of the present utility model, and wherein (a) is that front elevation, (b) are vertical views.
Below in conjunction with accompanying drawing structural principle of the present utility model and principle of work are elaborated.
With reference to Fig. 1, the utility model comprises a refrigeration compressor 1,1 high-pressure side of refrigeration compressor is connected by the inlet end of pipeline with discharge line valve 2, the endpiece of discharge line valve 2 is connected by annular space in the sleeve pipe 8 of pipeline and bushing type condenser/evaporator 3, the annular space lower end is connected by the inlet end of pipeline with throttling valve 5 in the sleeve pipe 8 of bushing type condenser/evaporator 3, the outlet of throttling valve 5 is connected with pipe core 7 lower ends of bushing type condenser/evaporator 3 by pipeline, the upper end of pipe core 7 is connected by the inlet end of pipeline with suction line valve 6, and the endpiece of suction line valve 6 is connected with refrigeration compressor 1 low pressure end by pipeline.In addition, the exterior arrangement of bushing type condenser/evaporator 3 has cooling electric fan 4.
With reference to Fig. 2, this condenser/evaporator 3 comprises the pipe core 7 of many parallel connections, is with corresponding sleeve pipe 8 outside the every pipe core 7.
With reference to Fig. 3, this condenser/evaporator is another embodiment of the used condenser/evaporator of the utility model 3, comprises the pipe core 9 of a screw type, is with corresponding screw type sleeve pipe 10 outside it.
After cooled compressor 1 compression of refrigeration working medium gas, ring-like space in discharge line valve 2 enters the sleeve pipe 8 (or 10) of bushing type condenser/evaporator 3, with the air outside cryogen in the heat transferred pipe core 7 and the sleeve pipe 8 (or 10), realize cooling, condensation and cold excessively in the sleeve pipe side.Cross liquid after cold through behind the throttling valve 5, the cryogen that generation can be freezed, this fluid returns the following end entrance of the pipe core 7 (or 9) of bushing type condenser/evaporator 3, and the heat of absorption sleeve pipe side hot fluid is finished evaporation, superheating process in pipe.Gas refrigerant after overheated returns compressor 1 through suction line valve 6 and carries out next one circulation.For ease of debugging, also is furnished with cooling fan 4.
With reference to Fig. 2, the high temperature, the gases at high pressure that are come by refrigeration compressor enter ring-like space in the heat exchange jackets 8 by last end entrance, flow from top to bottom, realize cooling, condensation and cold excessively, are flowed out by the outlet of lower end, sleeve pipe 8 inner ring type space then.Low temperature after the throttling, low-pressure fluid are entered in the pipe core 7 of heat interchanger by the following end entrance of pipe core 7, flow from bottom to top, finish evaporation and superheating process, at last by the upper end outlet outflow heat exchanger of pipe core 7.
With reference to Fig. 3, the high temperature, the gases at high pressure that are come by refrigeration compressor enter annular space in the heat exchanger helical molded cannula 10 by last end entrance, flow from top to bottom, realize cooling, condensation and cold excessively.Flow out by the lower end outlet then.Low temperature after the throttling, low-pressure fluid are entered in the pipe core of heat interchanger by 9 times end entrances of pipe core, flow from bottom to top, finish evaporation and superheating process, at last by pipe core 9 upper ends outlet outflow heat exchanger.
Compare with the refrigeration compressor life test apparatus that generally adopts now, this utility model has the following advantages
A. reducing this device of initial cost only needs a heat interchanger, and the cost of this heat interchanger is lower than the cost of condenser and evaporator in the existing apparatus, has reduced the manufacturing cost of device.
When b. the saving energy test device was worked, main exchange heat was to carry out between the hot and cold refrigeration working medium of internal system, and only having few is most to take away by cooling air, can economize on electricity more than 50%.
