Abstract

PURPOSE:To enable instant heating, by a providing an automobile cooler-heater with an indoor heat exchanger air supply quantity controller exclusive for a heat pump, so that the quantity of supplied air is regulated to be low and the pressure at the high pressure side of the cycle and the temperature of blown-off air are heightened. CONSTITUTION:When a compressor 1 is driven, a coolant flows, as shown by arrows in the drawing, in heating operation and the pressure at the high pressure side of the cycle rises. If the quantity of blown-off air from an indoor heat exchanger 8 is a low value G1, the pressure at the high pressure side rises further and the temperature of the blown-off air can be made higher. However, the pressure at the high pressure side cannot exceed a limit level P1 for the protection of the coolant and component appliances. When the pressure has reached a level (a), a high pressure switch 11 acts so that an indoor heat exchanger air supply quantity controller 14 is operated by the output of the switch to change the quantity of the air to a high value G2. As a result, the pressure drops to a level (b). When the temperature of the air falls to such a level as to give no feeling of uncomfortableness and the pressure becomes the low level P2, a low pressure switch 12 acts to operate the controller 14 so that the quantity of the blown-off air becomes the value G1 again and its temperature is heightened.
