Abstract: PURPOSE:To protect a device and normalize the action of a system by a method wherein, when refrigerant becomes insufficient in a refrigerant heating section and hence the refrigerant is overheated, such state is immediately detected in a cooling/heating device wherein refrigerant is heated by high temperature gas such as combustion gas. CONSTITUTION:When temperature output of an overheat temperature detecting means 25 is equal to or higher than a certain value, a controller 29 outputs an overheat signal.
