Embodiment
See also Fig. 2, the utility model performance test system for refrigeration compressors comprises main system 10, water tank 20, cooling equipment 30 and heat exchanger 40.Wherein main system 10 is exactly the system that the 5.1.1 joint of GB/T 5773-2004 standard is drawn, as shown in Figure 2.At least comprise compressor 11, condenser 12 in the main system 10, throttle valve (expansion valve) 13, vaporizer 14 etc.Wherein vaporizer 14 is positioned at the top of a heat insulation pressurized container 140, and heater 141 is positioned at the bottom of described heat insulation pressurized container 140 and by the second refrigeration agent submergence.Described vaporizer 14, heat insulation pressurized container 140, heater 141, second refrigeration agent have been formed calorimeter instrument 15 jointly.
In main system 10, in the condenser 12 cooling water pipeline is arranged, there is the cooling water that circulates that condenser 12 is cooled in this cooling water pipeline.The water outlet 121 of this cooling water pipeline will be discharged into water tank 20 afterwards by heat exchanger 40 again by the higher water of condenser 12 back temperature.Heat exchanger 40 can be air cooling heat exchanger or water cooling heat exchanger etc.Water in the water tank 20 cools by cooling equipment 30 and is controlled in the certain temperature range, and the water in the water tank 20 after the cooling is discharged into the water intake 122 of cooling water pipeline again.
The utility model performance test system for refrigeration compressors will be lowered the temperature through heat exchanger 40 earlier for the first time by the cooling water of condenser 12 back higher temperatures, be discharged into water tank 20 again by cooling equipment 30 cooling for the second time.Wherein heat exchanger 40 can adopt normal temperature air or the cooling of normal-temperature water natural cooling, not consumes energy.So just, reduced cooling equipment 30 in order to reduce and to control the energy consumption that water temperature produced in the water tank 20, thereby made the whole test energy saving of system.
