Abstract
An air conditioning system including a variable speed compressor configured to operator at faster and slower speeds. The system includes an evaporator and a thermal expansion valve for regulating the flow of a refrigerant from the compressor to the evaporator. The system includes a flow restricting device in a flow path from the thermal expansion valve to the evaporator thereby increasing the efficiency of the system when the compressor is operating at slower speeds.
Claims10
An air conditioning system comprising:
- an evaporator containing refrigerant, wherein the evaporator is configured to exchange heat with a surrounding environment;
- a metering device for regulating the flow of refrigerant into the evaporator, wherein the metering device is configured to regulate the flow into the evaporator based, at least in part, on the pressure sensed in a flow path to the evaporator;
- a compressor for compressing refrigerant and providing liquid refrigerant to the metering device;
- wherein the system is configured so that refrigerant flowing from the metering device into the evaporator passes through a flow restricting device located in the flow path.
An air conditioning system including a variable speed compressor configured to operate at faster and slower speeds, an evaporator and a thermal expansion valve for regulating the flow of a refrigerant from the compressor to the evaporator, wherein the thermal expansion valve is configured to control the flow of the refrigerant into the evaporator based on a temperature sensed at the outlet of the evaporator and a pressure sensed at the inlet to the evaporator;
- wherein the system includes a flow restricting device in a flow path from the thermal expansion valve to the evaporator thereby increasing the efficiency of the system when the compressor is operating at slower speeds.
