The utility model is composed of a refrigeration compressor, a condenser, a condenser evaporator and a subcooler. An outlet of the refrigeration compressor is connected with a side condensing inlet of the condenser. A side condensing outlet of the condenser is connected with a side cooling inlet of the subcooler. A side cooling outlet of the subcooler is connected with a side evaporating inlet of the condenser evaporator by a liquid flow meter and a throttling valve. A side evaporating outlet of the condenser evaporator is connected with an inlet of the refrigeration compressor by a cooler. The outlet of the refrigeration compressor is also the side condensing inlet of the condenser evaporator. The side condensing outlet of the condenser evaporator is connected with the side cooling inlet of the subcooler. The fluid flowing through an evaporating passage of the condenser evaporator and the fluid in a condensing passage of the condenser evaporator can carry out countercurrent flow. The utility model can make use of cold source in the system to reduce running expenses and cost of equipment.
Description
One, technical field
The utility model relates to a kind of testing apparatus of refrigeration compressor performance, especially high-power refrigeration compressor performance measurement device.
Two, background technique
The refrigeration compressor performance test is to measure performance parameters such as its refrigerating capacity, consumed power under certain operating mode, and test method is with reference to relevant criterion such as ISO 917-1989, GB 5773-86.The refrigeration compressor performance test apparatus is the system of the specific working condition of simulation refrigeration compressor, can control the state of refrigeration agent in compressor inlet and outlet, measures the flow by the refrigeration agent of compressor simultaneously.The method of measurement of refrigerant flow commonly used has the second refrigeration agent calorimetric meter method, gas flowmeter method and fluid flowmeter method etc.Present high-power refrigeration compressor performance test adopts the gas flowmeter method in order to reduce testing expense more, enter refrigeration compressor again with refrigeration compressor exhaust step-down, after being cooled to the suction condition of regulation---promptly so-called " compression ring method ", owing to there be not condenser, vaporizer and corresponding cold and heat source in the common refrigeration system, so the equipment of system and operating cost are all lower.The shortcoming of " compression ring method " mainly contains: 1, because of adopting gas flowmeter (as orifice meter), its uncertainty of measurement big (general＞2%); 2, when refrigeration agent is non-azeotropic refrigerant, the composition of refrigeration agent in being difficult to guarantee to circulate.The high-power refrigerator performance testing device that adopts the second refrigeration agent calorimetric meter method or fluid flowmeter method at present be then because it need dispose jumbo low-temperature receiver and thermal source, causes equipment cost height, operating cost big.
Three, technology contents
Technical problem the utility model provides a kind of can reduce the high high-power refrigeration compressor performance measurement device of operating cost and equipment cost and accuracy.
A kind of high-power refrigeration compressor performance measurement device that is used for the refrigeration compressor performance test of technological scheme, by refrigeration compressor 1, condenser 2, condenser/evaporator 3 and subcooler 4 are formed, refrigeration compressor 1 outlet links to each other with the condensation side import of condenser 2, the condensation side outlet of condenser 2 is connected with the cold side import of subcooler 4, the cold side outlet of subcooler 4 is connected with the evaporation side import of condenser/evaporator 3 with throttle valve 7 through fluid flowmeter 5, the evaporation side outlet of condenser/evaporator 3 links to each other through the import of cooler 9 with refrigeration compressor 1, the outlet of refrigeration compressor 1 also links to each other with the condensation side import of condenser/evaporator 3, the condensation side outlet of condenser/evaporator 3 links to each other the fluid of the evaporation channel of the condenser/evaporator 3 of flowing through and the fluid reverse flow of condensation channel with the cold side import of subcooler 4.
Beneficial effect (1) is because condenser/evaporator has utilized intrasystem low-temperature receiver, thereby operating cost and equipment cost have been reduced, the utility model has saved and has been traditional condenser, the low-temperature receiver of evaporator arrangement, thermal source, make it have the lower advantage of energy consumption, subcooler, the employing of condenser and condenser/evaporator, make the utility model realize measuring the performance of refrigeration compressor with fluid flowmeter, and the reverse flow of fluid in the evaporation channel of condenser/evaporator and the condensation channel, can make cold fluid and hot fluid directly carry out heat exchange, in condensation side high temperature fluid cooling condensation, the fluid evaporator of evaporation side, overheated, therefore the fluid that flows out the evaporation side passage can obtain more heats, be enough to make the temperature of this fluid to surpass the inhalation temperature setting value that operating condition of test requires, thereby make the utility model between outlet of the evaporation side of condenser/evaporator and refrigeration compressor import, can adopt cooler, and cooler needs the duct thermostat of heating or cooling more simple, and is more favourable to the cost that reduces equipment.(2) by throttle valve and subcooler be connected and by throttle valve and being connected of cooler all making subcooler and cooler utilize intrasystem low-temperature receiver, thereby make operating cost of the present utility model and equipment cost lower, energy consumption is lower.(3) the utility model adopts fluid flowmeter to measure the flow of refrigeration compressor, and " compression ring method " gas flowmeter precision of adopting increases significantly, and circuit refrigerant air-liquid phase constituent is constant can guarantee that refrigeration agent is non-azeotropic refrigerant the time.
