Experimental Research of Performance on Water-Water Multi-functional System
A new type of water-water multi-functional system consisting of double four-way valve is studied. System fundamentals and the operation modes are introduced. Experimental research on operation characteristics of refrigerating capacity, heating capacity, suction and discharge temperature and pressure shows that the unit operates reliably long in different operation conditions, and that the variation of characteristics is within a reasonable range. Coefficient of performance of the unit in refrigerating and hot water mode is highest and EER reaches up to 5.2 with the minimal value approximately 4, as the service efficiency of the unit is improved by recovering the condenser heat to heat hot water.
