<p>PROBLEM TO BE SOLVED: To uniforming the temperature distribution of a bathtub by a method wherein either one control means between a control means for operating a compressor intermittently or another control means for controlling the output of the compressor is provided. SOLUTION: A heat pump bath hot-water supplier is provided with a compressor 1, an expansion valve 2, a refrigerant circuit 3, a supplying hot-water heat exchanger 4, a supplying hot-water circuit 5, a supplying hot-water tank 6, a bath heat exchanger 7, a bathtub 8 and a bathtub water circuit 9 in addition to a control means 10 and another control means 11. In this case, the control means 10 controls the intermittent operation of the compressor 1 based on the time of operation while the control means 11 controls the output of the compressor 1. According to this method, the operation of the compressor 1 is stopped by the control means 10 to prevent the bathtub water from being cooled in the bath heat exchanger 7, while the output of the compressor 1 is lowered by the control means 11 to restrain the cooling of the bathtub water in the bath heat exchanger 7.</p> |
