Abstract

PURPOSE:To reduce the leakage of water when a secondary circuit is damaged, by dividing a cooling/heating device by a heat exchanger into a primary circuit having a water feeder and the secondary circuit having a radiator and by providing a leaking water detection stopper in the secondary circuit. CONSTITUTION:The cooling/heating device comprises the primary circuit 22 to which the wate feeder such as a cistern 34 si connected, and the secondary circuit 28 which is connected to the primary circuit 22 not through a waterway but through a heat passage. The radiator is provided in the secondary circuit 28. When water leaks from the radiator 30 or the vicinity thereof, the quantity of the water is a very small part of that in the secondary circuit 28 and a secondary circulation pump 3 is stopped by the leaking water detection stopper 32. The quantity of the leaking water is thus limited.
