This paper is to develop heat pump system can use cold storage together with floor panel heating. The system stores the wasted heat with thermobank during refrigeration cycles and its heat is used floor panel heating and hot gas defrost. This system reduces
condensation load and its room maintains the constant temperature for working with cold storage, and then changes over heat pump for floor panel heating. Reducing defrosting time
with thermobank the system can prevent temperature increasing in the cold storage. Heat pump system is investigated experimentally and analysed under cold storage and floor panel heating. The average performances of the refrigerator with cold storage and the heat pump with floor panel heating, under some test conditions, are shown a good COP of 3.0 and 4.0, respectively.
