The quanity of refrigerant in system.
A storage tank located in the suction line before the compressor. It allows small amounts of liquid refrigerant to boil away before entering the compressor.
A device used to exchange heat between air and another medium at different temperature levels. Such as: air to air, water to air, or air to refrigerant.
Air Heat Exchanger
A thin piece of flexible material used between two metal plates to prevent leakage.
The component in a refrigeration system that transfers heat from by condensing refrigerant.
Any substance in a refrigeration system that is foreign to the system, particularly if it causes damage.
A device used in a refrigerant line to remove moisture.
A tool that may have more than one guage with a valve arrangement to control fluid flow.
A vapor pump that pumps vapor (refrigerant to air) from one pressure level to a higher pressure level.
Another term for pressure, usually referring to liquid or gas.
The volume at the top of the stroke in a compressor cylinder between the top of the piston and the valve plate.
An external type of compressor motor drive as opposed to a hermetic compressor.
Substance in a refrigeration system drier that collects moisture
The pressure on the low pressure side of a refrigeration system (also known as suction pressure).
The final device in many water cooled systems, which rejects heat from the system into the atmosphere by evaporation of water.
The end structure of an electric motor that normally contains the bearings and lubrication system.
A complete unit that includes the compressor and the condensing coil.
A compressor used for large refrigeration systems. It is not a positive displacement but is similar to a blower.
A reciprocating compressor valve design with a low clearance volume and a large bore.
A term applied in the industry to refer to the tubing or piping from the condensor to the expansion device.
The term applied to refrigeration systems when the liquid line reaches the compressor
A term used to indicate the high pressure or condensing side of the refrigeration system.
The component in a refrigeration system that absorbs heat into the system and evaporates the liquid refrigerant.
An off-center device that rotates in a circle around a shaft
Same as the compressor shaft seal
