Working principle of chiller:

The working principle of the chiller is mainly based on the refrigeration cycle. Taking water-cooled chiller as an example, its refrigeration process includes four main links: compression, condensation, throttling and evaporation. The compressor inhales the low temperature and low pressure refrigerant gas after evaporation and refrigeration, compresses it into high temperature and high pressure gas and sends it to the condenser. The gas in the condenser is cooled into normal temperature and high pressure liquid, and then throttled into low temperature and low pressure wet vapor by the thermal expansion valve. The wet vapor enters the evaporator, absorbs the heat of the frozen water to reduce the temperature of the water, and the refrigerant is inhaled by the compressor after evaporation, so the cycle repeats.

Shanghai Shang Yu Refrigeration Equipment Co., Ltd. is a high-tech enterprise engaged in refrigeration equipment research and development, design, production, sales, installation, etc., at the beginning of the 21st century, set up a factory in Fengxian District of Shanghai and introduced foreign advanced technology, specializing in the design of military electrical and freezing, cooling products. After nearly two decades of development, Shanghai Shangyu has become an expert in the manufacture of industrial refrigeration and civil air conditioning, "P, T, C, Q, S" (talent, technology, cost, quality, service) theory and practice has cast Shanghai Shangyu's leading position in the industry, and it is also the core competitiveness of the company's development. The refrigeration equipment control system developed by the company is widely used by enterprises in China and around the world.

At the moment, Shanghai Shangru research and development of water-cooled screw chiller, water-cooled screw cryogenic unit, evaporative chiller, full liquid chiller, air-cooled screw chiller, air-cooled heat pump unit, air-cooled box unit, water-cooled box unit products have been widely used in chemical, chemical fiber, plastics, grease, food, pharmaceutical, military, printing, painting, electroplating, electronics and other industries to become a process refrigeration Home, for the rapid development of Chinese industry to provide efficiency and quality assurance.
