Air conditioner

Abstract

Abstract PURPOSE: To enable to accomplish most comfortable air-conditioning under any circumstances, by adding to a cooling operation controlling system a control system capable of changing the setting temperature and cooling capacity of an air conditioner according to the level of humidity. CONSTITUTION: A refrigerating cycle controlling circuit, constituted by connecting a compressor 1, outdoor heat exchanger 2, capillary tube assembly 3 and indoor heat exchanger 4 successively by coolant pipes 5, is composed of a circuit section HD for detecting the humidity of air in the room to be air-conditioned and changing the setting temperature, cooling capacity and dehumidifying capacity and a circuit section TD for effecting ON-OFF control of the compressor through detection of the room temperature. When the humidity detected by a humidity sensor RD is higher than a setting value, a relay RY1 is energized and a contact RY1B is opened, so that the setting value of a temperature setting resistance RBT is raised. Resultantly, operating speed of the compressor 1 is lowered and it is detected by a switch 8, which results in reduction in the operating speed of a fan 7 and hence the cooling capacity of the air conditioner. At the same time, a by-pass solenoid valve 3C is closed for promoting the dehumidifying operation. COPYRIGHT: (C)1982,JPO&Japio
