THIS UNIT IS FOR CAP TUBE SYSTEMS AND DOES NOT COME WITH A LIQUID RECEIVER NOR IS ONE NEEDED FOR CAPILLARY TUBE SYSTEMS. The refrigerant capillary tube is a vital component to a refrigerator or air conditioner, because it condenses the amount of refrigerant supplied to the evaporator. Capillary tube is the simplest of all devices of the account. 0000012507 00000 n rs-44 is particularly effective in unitary air conditioning systems replacing r22 in an existing system with a capillary tube … 0000074434 00000 n through the capillary tube with fall of temperature below the ambient, that may cause the undesired flow of heat from the ambient to the refrigerant inside the tube and reduces its heat extraction capacity from the refrigerating space and hence reduces the refrigeration effect. These newly developed selection charts can be practically used to select capillary tube size from the flow rate and flow condition or to determine mass flow rate directly from a given capillary tube size and flow condition.
