PROBLEM TO BE SOLVED: To improve maintenance work conservation of a bath purifying system and reliability of equipment. SOLUTION: The heat pump bath purifying system comprises a bath circulating circuit having a bathtub 1, a circulating pump 2, a heating heat exchanger 3, a temperature regulating heat exchanger 5 and a filtering means 6, a compressor 7, a condenser 8, a pressure reducing unit 9, a water-cooled evaporator 10 having heat exchanging relation to the exchanger 5, a temperature sensing means 11 and a control means 12. Water of the bathtub 1 is heated by the exchanger 3 to a high temperature at which bacteria die. The means 12 controls a flow rate of the pump 2 based on a signal of the means 11 to control a heating temperature. High temperature hot water outputted from the exchanger 3 is cooled to a temperature by being deprived of heat by low temperature refrigerant gas of the compressor 7 by the exchanger 5, filtered by the means 6, and returned to the bathtub 1. |
