Abstract: The cooling (heating) capacity and energy efficiency of air conditioning heat pump devices are the main indicators for evaluating their performance. In laboratory steady-state performance measurement, in order to reflect the improvement of partial load performance of air conditioning heat pumps, performance evaluation has gone through a process from "point" evaluation to seasonal performance evaluation, but its essence is the steady-state operating parameters under given heat source side and usage side conditions, as well as specified compressor and fan operating conditions. With the development of the control level of air conditioning and heat pump devices, in order to further improve the automatic control characteristics and quality control of air conditioning and heat pump devices, reviews the methods for measuring performance based on variable loads at home and abroad, including static compensation method (chamber induced load) and dynamic compensation method (virtual building load). Essentially, virtual air conditioning heat and humidity load is applied to the inside of the laboratory room, And it is required that the air conditioning and heat pump device use automatic control technology to adjust the indoor temperature to the set temperature based on the indoor load, in order to obtain the performance of the unit during this period. Aims to provide reference or basis for establishing a measurement scheme for simulating the actual operating performance of air conditioning heat pump devices in the laboratory.
