PURPOSE:To improve the comfortableness of room heating by a constitution wherein a compressor is controlled due to indoor temperature when both the floor heating and the heating by indoor blower are performed and due to floor temperature when only the floor heating is performed in the titled heating apparatus, in which both a floor radiator and an indoor heat exchanger are utilized. CONSTITUTION:When the utilization of a floor radiator 5 only is requested, the compressor 1 is put into operation by turning a power supply 11 ON, an operating switch 12 ON and by changing-over a cooling-heating change-over switch 13 to a hot side (c), a four-way valve 2 to a heating circuit, and a change-over switch 14 to a floor-heating side (e). After that, the compressor 1 and an outdoor blower 10 are ON-OFF-controlled by the actuation of a floor temperature sensor relay 17 of the floor temperature sensor (not shown) of the floor radiator 5. when the combined utilization of the floor radiator 5 and the indoor blower 4 is requested, the change-over switch 14 is changed-over to a floor-heating plus hot-air side (d). Consequently, a room temperature sensor switch 16 is put into operation by a room temperature sensor (not shown) in order to ON-OFF- control the compressor 1, an indoor blower 4, and the outdoor blower 10. Due to the constitution as mentioned above, the detection of temperature is ensured and the comfortableness can be improved. |
