Title: Heat pump type hot water apparatus
Inventor: KUROKI JOJI
IPC: F25B47/02
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To provide a heat pump type hot water apparatus which can carry out a defrosting operation without lowering reliability of a system and without increasing costs. SOLUTION: While a normal operation is being carried out wherein liquid in a hot water tank 2 is passed through a hot-water heat exchanger 5 to heat it, if the outlet temperature of an outdoor heat exchanger 7 falls to about -5 deg.C (sensed temperature of a temperature sensor), the normal operation is changed over to a defrosting operation. In the defrosting operation, operation of a water pump 3 is stopped, and opening of an expansion valve 6 is made larger than that of the normal operation (e.g. full open). Thus, the amount of heat energy released at the exchanger 5 from hot gas delivered from a compressor 4 can be reduced, and temperature drop due to reduction in pressure at the valve 6 can be reduced. As a result, the temperature of the hot gas delivered from the compressor 4 is not greatly decreased, and hence defrosting is effected at the exchanger 7.
