Title:
HEAT PUMP TYPE COLD AND HOT WATER GENERATING DEVICE
Document Type and Number:
Japanese Patent JP2018138850
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a cold and hot water generating device that can be miniaturized to install a cold and hot water type radiation panel air conditioning in a small space and expand use of it.SOLUTION: A heat source machine 1 with a minimum capacity that is necessary for a cold and hot water type radiation panel air conditioning is assembled with a small-sized thermal storage tank 2, solenoid valves 5, 6, a circulation pump 4, an expansion valve, sensors and the like in a compactification manner, and also includes an air heat exchanging function. Efficiently circulating cold and hot water in the thermal storage tank 2 by the solenoid valves 5, 6 completes a heat pump type cold and hot water generating device that is compact, lightweight and saves power.SELECTED DRAWING: Figure 1
