摘要： A refrigerant flow control system associated with a refrigerant circulating circuit having a compressor, a condenser, an expansion valve and an evaporator, includes a branch pipe extending from a discharge pipe of the compressor and having on sealed free end. A first temperature sensor is disposed on the branch pipe near the sealed free end for detecting a condensation temperature of a refrigerant which is condensed in the branch pipe. A second temperature sensor is disposed on the discharge pipe of the compressor for detecting a temperature of the gaseous refrigerant discharged from the compressor. The signals representative of the condensation temperature and the temperature of the discharge gaseous refrigerant are inputted to a control device. The control device calculates a difference between the two detected temperatures, and a degree of superheat of the discharged gaseous refrigerant and transfers to the expansion valve a command signal representative of the calculation results, thereby controlling an opening of the expansion valve.

摘要： The present invention is characterized by selecting, during heating, the hot air blowing mode in which a compressor and a blower for an indoor heat exchanger are each controlled as to r.p.m. to control the temperature of outlet air blown from an air conditioner at a higher temperature, and the normal mode in which the room temperature is controlled. Also, as required, an air passage of the outlet is set to be narrow to blow hot air in a confined space, or the air passage of the outlet is set wide to disperse warm air during normal operation.

摘要： An expansion valve has a refrigerant inlet passage, a refrigerant outlet passage, a valve chest to which both the passages open, a diaphragm chamber communicating with a heat-sensitive bulb through a tube of small diameter, and a valve body actuated in response to the operation of a diaphragm, the valve body being disposed facing a valve seat in the valve chest to regulate a passage defined between the valve seat and the valve body, to thereby control the flow rate of a refrigerant. The valve seat is adapted to be axially movable along the inner wall of the valve chest. In addition, means are provided for moving the valve seat in accordance with a change in pressure in the refrigerant circuit.

A non-azeotropic mixture refrigerant comprising at least two kinds of refrigerant of different boiling temperatures mixed together is charged in and circulated through the refrigeration cycle. The mixing ratio of the azeotropic mixture refrigerant circulated thorough the refrigeration cycle is controlled substantially constant.
