Ammonia refrigerant open screw compressor

This refrigeration system has been entirely designed and its installation drawings prepared by our company, along with the provision of related refrigeration equipment. The cold storage facility spans 8,000 square meters, maintaining an internal temperature of -18°C. It primarily stores seasonings and other perishable goods that require refrigeration. Additionally, there are two quick-freezing machines, each capable of freezing 2 tons of goods per hour. The refrigerant used is R717, while the refrigeration compressor employs an open-type screw compressor with two-stage compression for enhanced efficiency and energy savings. The refrigeration system utilizes a bucket pump for liquid supply and an evaporative condenser. The cold storage insulation system features 150mm polyurethane insulation panels. Currently, the entire refrigeration system is undergoing steady installation.
