PROBLEM TO BE SOLVED: To raise the efficiency of a system itself and to contribute to ecology, performing the heating of fluid by dividing it into two stages, and at the same time, retrieving residual heat without disposing the heated fluid, when that which heats the fluid using a heat pump system is provided.SOLUTION: A fluid flowing in a pipe line is primarily heated by a first heat exchanger, and is further secondarily heated by a second heat exchanger installed in the downstream side and stored in a storage tank. The primary heating is performed with the first heat exchanger by retrieving residual heat which a disposed fluid has after the fluid stored in the storage tank is utilized. The secondary heating is configured to be performed by the second heat exchanger which functions as a condenser in the heat pump system equipped with a compressor, a condenser, an evaporator and the pipe lines connecting those. The disposed fluid whose residual heat is retrieved by the first heat exchanger is used to supply residual heat to a coil pipe for heat exchange which functions as the evaporator in the heat pump system equipped with the compressor, the condenser, the evaporator and the pipe lines connecting those. |
