Claims

[Claims for Utility Model Registration] 1. In an air conditioner having a refrigeration cycle in which a variable capacity compressor, an evaporator, a pressure reducing device, and a condenser are connected in sequence, the amount of pressure reduction in the pressure reducing device can be switched by a switching valve. A sensor is provided to detect the cycle state during the refrigeration cycle, and this detected value is compared with preset upper and lower limit values, and the switching valve is controlled according to the comparison result. An air conditioner characterized by being equipped with a control device. 2. The air conditioner according to claim 1, wherein the sensor is a temperature sensor for detecting discharge temperature and is installed in a discharge pipe of a variable capacity compressor.
