Water cooled screw type low-temperature refrigeration unitadvantage. It is designed for production processes that require low-temperature treatment such as freezing, refrigeration, and industrial coolingLJR-WThe cooling capacity range of the water-cooled screw series is116KWto2560KWThe temperature adjustment range of chilled water is-35℃ to10℃. Multiple safety protection devices such as phase sequence protection, motor overload protection, antifreeze protection, and high and low voltage protection are installed on the unit equipment. The compressor adopts unloading and voltage reduction starting to avoid impact on the power grid. Additionally, it can still be producedR134a、R407C、R404AWaiting for environmentally friendly refrigerants, saltwater and other products.（due towater-coolingopen typeLow temperature refrigeration unitmodelCould not provide a detailed list.

water-coolingopen typeLow temperature refrigeration unitWorking principle

The high-pressure and high-temperature gas from the compressor enters the condenser, and the heat is carried to the outside by the cooling towerOperating substancesBecoming a high-pressure room temperature liquid, the high-pressure room temperature liquid enters the expansion valve throttling mechanism for pressure reduction, and some of the liquid flashes into vapor. These low-temperature and low-pressure gas-liquid two-phase mixtures enter the evaporator, where they exchange heat and cool with the high-temperature hot water of the customer's industrial equipment. The medium inside the evaporator becomes vapor and returns to the compressor for re compression, completing a cycle. The chiller unit continuously exchanges heat and cools, supplying mechanical equipment and products for cooling.
