S i 11 Tube b Heat Exchanger THE CAPILLARY TUBE REFRIGERATION SYSTEM Basics how a capillary system operates Starting at the motor compressor the refrigerant from a low pressure gas is compressed to a high pressure gas and pumped into the condenser In the condenser with the condenser fan motor circulating air over the refrigerant inside the condenser coil the refrigerant is condensed from a high pressure gas to a high pressure liquid The high pressure liquid then leaves the condenser and enters the drier which is designed to remove moisture amp contaminants that maybe in the system Liquid refrigerant enters the capillary tube the pressure is reduced as it enters the evaporator coil the liquid refrigerant starts to boil as heat is picked up in the evaporator and the refrigerant changes to a low pressure gas The low pressure gas enters the accumulator to boil off any liquid refrigerant prior to returning to the compressor through the suction line 32 Refrigeration continued The Capillary Tube The capillary tube is probably the simplest of all metering devises The capillary tube is commonly used as a metering devise used on self contained refrigerators and freezers It is constructed of a single tube with inside diameter in the range of 026 to 090 inches It is between the drier amp the evaporator coil and a large portion of it maybe coiled either at
