VRF多联机性能测试实验台的设计与建立

Abstract

Abstract: According to the American Standard ANSI/AHRI 1230-2010 《Variable Refrigerant Flow Rate (VRF) Multi-connected Air Conditioning and Heat Pump Equipment Performance Evaluation a set of 48HP multi-line integrated test benches was designed and constructed with a certain equipment manufacturer. The test methods of wind tunnel air enthalpy difference method and liquid refrigerant method are mainly adopted, and the test requirements for multi-connection of air source and water source heat pump are met at the same time. In addition to satisfying the technical requirements of environment temperature and humidity measurement and control, temperature field, air leakage rate and other technical requirements of VRF multi-line through experiments, and the average energy-saving is over 20% more than conventional control means, because of the effective energy-saving control method.

Key words: Multi-line test bench, Temperature field, Temperature and humidity measurement and control, Air leakage rate, Energy saving
