The Choice Of The Capillary Tube
The physical layout of the components of the refrigeration unit to dictate the minimum length of the capillary tube that can be used. The maximum length is based on the economy. After the pipes in diameter from selected lengdi varies to meet the flow rate requirements of the system. Any excess of the tube coiled in the side of the condenser to provide additional hypothermia.
Tlie spacer final length and inner diameter of the capillary tube is installed ENT applications using charts and tables show that the refrigerant mass flow in accordance with the operating conditions. Some of the diagrams on the basis of mass flow rate in the listed condenser pressure. Others point to the correction factors based on the lid of the length of the tube, its inner diameter and number of hypothermia. These graphics are refrigerant specific and manufacturers presented in the literature and ASHRAE HandbookCooling. The expected flow is calculated by multiplying the projected flow of the correction factors to determine the actual consumption through the tube cover during operation. If the die tube, estimated meets the requirements of the application, it is chosen.
