<p>A refrigerant leakage at an expansion valve (52) is assumed from the result of detection by pressure difference detection means (93, 97) for detecting the difference between high and low pressure in a refrigeration cycle. A control means (81) sets a standard temperature (T3) to a value corresponding to the extent of the refrigerant leakage at the expansion valve (52) based on the detection by the pressure difference detection means (93, 97).</p> |
