PURPOSE:To use a heat pump type foot warmer in place of an electric heater foot warmer by suspending an indoor unit of a heat pump air conditioner on the back surface of the foot warmer and using the foot warmer for space heating in winter, and for speed cooling or dehumidifying in summer and intermediate seasons. CONSTITUTION:An indoor unit 2 is suspended and fixed from and to the back surface of the foot warmer 1. In the space beating driving, when a switch 8 is turned ON, an air flow S1 induced by a blower 4 is heated at a heat exchanger 3 and turned into a hot air flow S2 which heats the room, and the temperature is adjusted to an appropriate value by a room temperature sensor 6 and a controller 8. In a space cooling operation, the foot warmer is set up and its legs 12 are folded inside, thus being installed near a window in the room. An air flow S 21 induced by the blower 4 is absorbed of its heat at the heat exchanger 3 and turned into a cool air flow S 22 to conduct space cooling. The temperature of the whole room is adjusted to an appropriate temperature, by the room temperature sensor 6 and the controller 8. In a defrosting operation, the rotation of the blower 4 is decreased as compared with the case of the space cooling operation, and the air flow amount is decreased and comfortable defrosting is carried out by the switch 7 and the controller 8. |
