It is evident that for all Refrigerants used, the combination of length & inner diameter of capillary tube are same in analytical method as well as in cooling capacity test. \����d��Nv0���/�/�� 0000001802 00000 n These charts are for Fan Cooled units only. 0000012112 00000 n Chart references single feed up to 2HP. If you have trouble signing in, contact your local Johnstone Supply store. For a capillary tube having an internal diameter of 1.63 mm and a length of 2.03 m, the required mass flow rate can be easily determined from this chart by knowing the condenser pressure and the degree of subcooling. The performance of capillary tubes with several length & inner diameter combinations for R22, R410A and R407c are investigated. Back Pressure High Back Pressure 1/8 Fan R12 108″ BC-5 84″ BC-5 48″ BC-5 1/8 Static R12 118″ BC-5 92″ BC-5 53″ BC-5 1/8 Fan R134a 118″ BC-5 96″ BC-5 58″ BC-5 1/8 Static R134a 130″ BC-5 106″ BC-5 64″ BC-5 1/6 Fan R12 … Additional charts available for 2-6 feeds up to 5HP. Often, separate charging curves and/or tables will be created for capillary tube and fixed orifice systems. R22 Retrofit R407F may require some system modifications such as changing the lubricant to POE oil. 0000012622 00000 n It is a fixed length of the small-diameter copper pipe, usually with internal diameter from 1/16 to 1/8 inch. <<2A6E0F8A07653A4AACE3D2CD2528C94C>]/Prev 422540/XRefStm 1452>> capillary tube 41 rs-44 rs-45 applications rsl rs-44 is suitable for use both in fixed orifice systems with an expansion valve. Reference chart for Bullet ® “Restricto” Capillary Tubing for All Refrigerants in Low, Medium and High Applications NOTE: This chart is average measurements for average conditions, and may have to be “fine tuned” for exact replacement. Capillary tube is the simplest of all devices of the account. Window air conditioners normally have 1 circuit and the recommended cap tube can be read directly from the chart.
