Abstract

PURPOSE: To perform a forcible convection cooling operation and a radiation heating operation by one apparatus by providing a radiation heat transfer tube in close contact with an outside plate of a forcible convection type air conditioner, supplying a heat exchange medium to the transfer tube at the time of heating, and operating the plate as a radiation heating plate. CONSTITUTION: When a changeover switch is set to a cooling, a low temperature heat exchange medium flows only through a forcible convection type heat exchanger 4 and a blower 5 rotates. Accordingly, the cooling and heating apparatus executes a forcible convection type cooling operation. When the switch is set to a heating, a high temperature heat exchange medium flows only through a radiation heat transfer tube 2. Its high temperature is conducted to an outside plate 1, and propagated to an exterior as a radiation heat via an outer surface of the plate 1. Since the blower 5 is stopped, the apparatus executes a radiation heating operation. When it is set to a quick heating, the high temperature medium flows both the exchanger 4 and the tube 2. And, since the blower 5 rotates, the apparatus simultaneously executes both the forcible convection heating operation and the radiation heating operation.
