The screw condensing unit is a core device of an efficient and stable refrigeration system, primarily composed of a screw compressor, condenser, expansion valve, and evaporator. It utilizes the principle of dual-rotor meshing in the screw compressor to achieve gas compression, featuring a compact structure, high energy efficiency ratio, long lifespan, and a wide load adjustment range. Utilizing environmentally friendly refrigerants such as R22 and R134a, it is widely applied in industrial refrigeration (such as cold chain logistics, food processing, and chemical processes) and large central air conditioning systems. Through forced heat dissipation condensation technology, it achieves rapid heat exchange. Coupled with an intelligent control system, it can precisely adjust the cooling capacity and energy consumption. Capable of operating in a wide temperature range from -40°C to 45°C, it is an ideal solution for continuous high-load refrigeration scenarios.
