Today, with the development of science and technology, many customers focus on using high and low temperature to improve the quality of products and reduce the cost of products. So what are the places to pay attention to when choosing a model?
Many customers ask for cooling when they use cooling water, which is generally used to dissipate heat. This method has been common for some time, but it has certain defects and cannot achieve a high-precision control. The purpose of temperature is that it is easy to receive natural temperature effects for natural water cooling and water tower cooling. Some temperatures are not available with the seasons, which is a very unstable way of cooling.
The chilled is different from the general refrigeration equipment. The first is the temperature range is different, -5 °C ~ -150 °C, can meet different temperatures, it is independent refrigeration system, will not be affected by temperature and environment, can reach High precision temperature purpose. Which of the freezer of the freezer tells you that Guanya Refrigeration uses secondary subcooling technology and the refrigeration is rapid. And the brand semi-closed piston compressor, semi-closed piston two-stage compressor, semi-closed screw compressor, the main brands are BOCK, Bitzer, Copeland, Hanbell, fusheng; the evaporator uses high-force plate heat exchanger, small size, efficiency high.
When using the chilled, the application range is relatively wide, and the needs of different industries are involved, and are widely used in high-tech industries such as petrochemical, medical, pharmaceutical, biochemical, freeze-drying, pharmaceutical, military and so on. When choosing, we should pay attention to the performance and technical parameters of the freezer. The large refrigeration unit adopts semi-closed screw compressor with economizer operation, and combined with electronic expansion valve to ensure energy saving. Complete set of imported cold controls (DANFOSS pressure controller, balancing valve, expansion valve, electromagnetic valve, drying filter, Emerson oil separator, ALCO sight glass, check valve, etc.). The unit cooling water circuit uses an intermediate heat exchanger to significantly improve the reliability and safety of the system.
The selection of the technical parameters of the freezer is very important. Everyone can choose the model that meets their needs according to their needs.
