PURPOSE:To get a comfortable thermal radiation of a cool head and a hot foot type conditioning in both cases of cooling and heating operations by a method wherein during heating operation, a part of an evaporator is assembled at an upper part of a panel main body and an entire condenser is assembled in a lower part of the panel main body and while during cooling operation, an entire evaporator is assembled at the upper part of the panel main body and a part of the condenser is assembled at a lower part of the panel main body. CONSTITUTION:When performing a heating operation, a heat exchanger is operated such that a part 4 of an evaporator is assembled at an upper part of a panel main body 1, a radiation surface 1a of the upper end of the panel main body 1 is inclined downwardly and a surface temperature of the panel main body 1 is decreased as its height is increased. Further, when as medium for a heat pump, non-azeotropic mixing coolant is used, a proper coolant corresponding to a utilization temperature range and its composition ratio are determined, thereby it becomes possible to make a proper temperature difference at a cooling part and a heating part in its upward or downward direction. Whereas, a heat exchanger for a cooling operation is made such that an entire evaporator 4' is assembled at the upper part of the panel main body 1 and a part 3' of the condenser is assembled at a lower part of the panel main body. The remaining part 8 of the condenser connected in series with the part of the condenser is mounted at an outdoor location and the upper end of the evaporator 4' is inclined downwardly.
