Description

technical field [0001] The invention relates to the technical field of air-conditioning heat pumps, in particular to a high-efficiency and energy-saving experimental temperature regulation system and a working method thereof. Background technique [0002] Existing air-conditioning heat pump products need to be tested in the laboratory before they are put into production. During the test, the temperature in the laboratory and the test water temperature must be adjusted according to the relevant test standards to complete the experimental test of the heat pump. The temperature in the laboratory is adjusted by the refrigeration system. The heat source of the refrigeration system is generally air source, water source and other energy sources; when the laboratory needs heating, the refrigeration system absorbs the heat in the air to heat; when the laboratory needs refrigeration, the refrigeration system The system dissipates heat to the heat source side to complete the adjustment...

Problems solved by technology

[0003] However, the adjustment speed of the existing laboratory temperature and the test water temperature is relatively slow. Since the heat or cold generated during the experimental temperature adjustment process is all discharged into the air, when the temperature on the heat source side is high, the test water temperature and the temperature in the laboratory The ambient temperature cools down slowly; when the temperature on the heat source side is low, the test water temperature and the ambient temperature in the laboratory rise slowly; therefore, the experimental temperature adjustment speed is slow, the process is troublesome, the efficiency is low, and a lot of energy is wasted
