Abstract: Based on the technical advantages of variable refrigerant flow pressors, the paper analyses
the advantages of air-cooled chiller and heat pump units, builds a variable volume scroll air cooled heat pump unit
performance test device, and studies energy saving, partial load performance characteristics, the temperature
control characteristics and electronic expansion valves application. It is found that the IPLV testing value of the
unit is , and the water temperature control accuracy is more pared to the normal scroll unit, up
to±℃. The experimental results provide theory and experience basis for the application of variable volume
pressors in air-cooled chiller heat pump units.
