Experimental Study on New Sewage Source Heat Pump Unit

Abstract:

By the analysis of the current technical conditions and existing problems, some improvements are carried out on the urban sewage source heat pump unit. are as follows: Refrigerants side switch sewage source heat pump system, dual-purpose heat exchange for evaporating and condensing & wastewater can enter the unit directly are of the main features of the improved units. Some important techniques, such as inverter screw compressor and variable compressor inner volume ratio are used to the improved unit at the same time. From the authoritative organization’s test, the improved sewage-source heat pump unit has an excellence performance in the nominal cooling and heating conditions.
