Abstract
A vapor compression type refrigeration apparatus is provided, in which refrigerant leakage is detected at an early stage. A temperature difference related to the theoretical heat dissipation of the condenser is compared with the actual temperature difference in heat dissipation (temperature difference between the condensation temperature and the outside-air temperature) of the condenser to determine whether there is a refrigerant leak.
