\n\tFirst, the selection of thermal
\nexpansion valve.<\/span><\/b>\n<\/p>\n

\n\t<\/span>\n<\/p>\n

\n\tIn the recirculating chiller refrigeration
\nsystem, the selection and installation of the expansion valve is very
\nimportant. Only the correct selection and installation can ensure the normal
\noperation of the unit. Therefore, when selecting the expansion valve, we can
\nuse the appropriate size of the thermal expansion valve according to the size
\nof the evaporator load and the evaporating temperature. The capacity of the
\ncommonly used expansion valve is about 20% larger than the evaporator heat
\nload. For small chiller refrigeration systems, gas-filled thermal expansion
\nvalves are generally used, and medium-sized recirculating chiller refrigeration
\nsystems mostly use adsorption-filled or mixed-filled expansion valves.<\/span>\n<\/p>\n

\n\t<\/span>\n<\/p>\n

\n\tSecond, the expansion valve
\ninstallation.<\/span><\/b>\n<\/p>\n

\n\t<\/span>\n<\/p>\n

\n\t1. The chiller expansion valve is installed
\nin front of the evaporator and is usually installed in a vertical position.
\nConsidering the ease of installation and maintenance, the cooling loss is small
\nand should be as close as possible to the inlet of the evaporator.<\/span>\n<\/p>\n

\n\t<\/span>\n<\/p>\n

\n\t2. The working
\ncondition of the expansion valve for the recirculating chiller has a direct
\nrelationship with the installation position of the temperature sensing package.
\nBecause the expansion valve completely adjusts the opening size of the
\nexpansion valve by the temperature change of the temperature sensing package.
\nThe temperature sensor package is installed on the pipe at the outlet of the
\nchiller evaporator. As the evaporator outlet pipe grows, its superheat
\ngradually increases. Therefore, the position of the expansion valve temperature
\nsensing package is directly related to the amount of fluid supplied from the
\nexpansion valve.<\/span>\n<\/p>\n

\n\tWe, LNEYA, have been engaged in the
\nmanufacturing and R&D of industrial refrigeration, heating and temperature
\ncontrol equipment for 15 years and have experienced designers and equipment
\nmaintenance personnel. The selection and installation of the expansion valve of
\nthe recirculation chiller can be said to be very complete, which not only
\nreduces the failure rate of the equipment, but also allows users to avoid loss
\nof production capacity during use. If you have any questions or needs regarding
\nrecirculation chillers, you can contact us at sales@lneya.com.<\/span><\/p>","protected":false},"excerpt":{"rendered":"
