摘要： A refrigeration system includes a compressor; a condenser; an expansion valve having a body with an expansion valve inlet and an expansion valve outlet; an evaporator all arranged in a refrigeration circuit; and a controller. The expansion valve body has a pathway comprising an inlet body capillary tube flow-connected to the expansion valve inlet, and an outlet body capillary tube flow-connected to the expansion valve outlet. The expansion valve comprises a solenoid operated valve element that is selectively positionable between the inlet body capillary tube outlet and the outlet body capillary tube inlet. The controller digitally controls the valve element to position the valve element either to allow flow through the pathway in an open position or to block flow through the pathway in a closed position.

摘要： In an air conditioner using a flammable refrigerant of the present invention, an inner diameter of a liquid-side connecting pipe is reduced to less than 42.5% of that of a gas-side connecting pipe. By reducing the inner diameter of the pipe in which a liquid refrigerant of the air conditioner is reduced, it is possible to reduce the amount of refrigerant to be charged into the system without decreasing the capacity and the efficiency.

摘要： A refrigerant flow metering device for use in a refrigeration system which uses a movable piston with a fixed flow passage in series with a variable area flow passage. The variable flow area is defined by the position of the piston relative to the containing housing. The position of the movable piston is a function of refrigerant pressure differential across the piston and the force of a spring member acting in an opposite direction on the piston. The variable flow area is defined as the clearance between a tapered fixed housing and the tapered portion of the movable piston. The piston is sealed via an “O” ring seal causing fluid to flow first through a fixed bore and then through the variable flow area.

摘要： A two-way flow solenoid-controlled expansion valve and receiver assembly for a two-way flow heat transfer system employing a refrigerant comprises a receiver and a valve body mounted on the receiver having two inlet/outlet passages. Either one of the inlet/outlet passages may be connected to a heat exchanger that switches from a condensing mode to an evaporative mode on refrigerant flow reversal while the other of these passages is then connected to another heat exchanger that operates in opposite manner. The inlet/outlet passages are each adapted to receive refrigerant from a condensing heat exchanger and deliver same through a separate check valve to the receiver and a flow control valve arrangement including two flow control valves independently operated by a proportional solenoid is operable to route and regulate refrigerant flow from the receiver to the other inlet/outlet passage that is connected to the heat exchanger that is then in an evaporative mode. The combined expansion valve and receiver assembly is also adaptable for use in more widely used refrigerant systems not requiring reverse flow by omitting certain components and making minor modifications.
