Problems solved by technology

[0003] However, the heat balance method has obvious disadvantages compared with the enthalpy difference method in terms of measurement time. Usually, more than 6 hours of continuous operation are required to keep the system in a stable and balanced state, while the detection time of the enthalpy difference method is generally 3 to 4 hours. The reason is that there are too many adjustment variables in the heat balance laboratory, and the most important variables include cooling water flow, temperature, electric heating power, humidifier power, etc., especially for cooling water, which requires continuous supply for more than 6 hours. cause a lot of waste of energy
At the same time, there are few researches on variable adjustment control methods in thermal balance laboratories at home and abroad, and the simultaneous adjustment of multiple variables without locking is generally used, which causes energy waste and affects the indoor and outdoor thermal balance effect, thus easily causing measurement errors.
Therefore, it is necessary to develop an energy-saving control method and system for an air-conditioning heat balance laboratory to solve the problems of consuming a lot of time and energy and causing errors during the heat balance test.

Description

technical field [0001] The invention relates to the technical field of air-conditioning detection, in particular to an energy-saving control method and system for an air-conditioning heat balance laboratory. Background technique [0002] The product performance of an air conditioner mainly reflects the cooling capacity, heating capacity, COP and power consumption. At present, the detection of performance indicators usually uses the enthalpy difference method and the heat balance method. To determine the performance of the air conditioner, the input heat and humidification amount are used to balance the cooling capacity and dehumidification capacity of the air conditioner under test, or the heat taken out to balance the heating capacity of the air conditioner under test. Generally speaking, the installation of the room air conditioner under test in the heat balance test room is closer to the actual use state. At the same time, the steady-state capability measurement adopted b...
