<p>A heat pump type cold/hot water supplying system is provided to reduce temperature difference between set temperature and real temperature of water and to improve energy efficiency. A heat pump type cold/hot water supplying system comprises an outdoor unit part(10), an indoor device part(20), a circulation unit(30), and a general controller(40). The outdoor unit has an outdoor device(10A) supplying and recovering heating medium using a heat pump. The indoor device part has a plurality of water heat exchangers(21), an expansion valve, and an independent controller(20A). The water heat exchangers are connected with the outdoor device of the outdoor unit part through a pipe. The expansion valve connects the water heat exchanger to the outdoor device. The independent controller controls the expansion valve. The circulation unit has an electromotive pump(31) transferring water of the water heat exchanger forcedly. The general controller applies a first signal to the independent controller to allow real temperature of the heating medium to be inputted as the virtual temperature which is within a temperature permission of the independent controller.</p> |
