Heat pump type heating

Abstract

Abstract PURPOSE:To obtain a comfortable room temperature at all times at what conducts hot air heating and floor heating by means of the condensation heat of a refrigerant, by correcting automatically a set temperature at a heating space by having the operation time of hot air heating alone and the operation time of the combination of hot air heating and floor heating. CONSTITUTION:A compressor 2, a four way valve 3 for cooling/heating changeover, an indoor heat exchanger 5, an expansion valve 6, an outdoor heat exchanger 8 and a floor heating panel 9 are connected through piping, and a sealed cycle is constituted. The indoor heat exchanger 5 and the floor heating panel 9 are connected in parallel through solenoid valves 11, 12 and 13, 14 provided on both sides of them. And the compressor 2, an indoor fan 4 and respective solenoid valves 11-14 are controlled by means of a controller 17 in accordance with operation modes and the outputs of respective temperature sensors 15, 16 provided at the indoor heat exchanger 5 and the floor heating panel 9. In this case, it is arranged that a set temperature at a heating space is automatically corrected by means of the operation mode of hot air heating alone and the operation mode of the combination of hot air heating and floor heating.
