Chillers, also known as ice machines, freezers works is a vapor compression refrigeration, that is, when the use of liquid refrigerant vaporizing heat, steam condensation principle exothermic refrigerate. In refrigeration technology, liquid refrigerant evaporation means to reach into gaseous boiling process. Liquid into gas must absorb heat energy from the outside world can be achieved, and therefore is an endothermic process, the temperature of the liquid refrigerant evaporates when called evaporation temperature, condensation of steam cooling means equal to or lower than the saturation temperature of the steam is converted to a liquid state. Nanjing Bo Sheng cryogenic refrigeration chiller features 1. Total power no fuse, breaker? 2. 3. low voltage frost protection? 4. ice water pump overload the compressor overload protection 5. 6. Cooling water pump overload 7. 8. protection fault indicator system fault alarm system according to ice pressure release loop 10. By-pass multi-stage delay start control 11. This model series for use in Central Cooling way to facilitate centralized management 12. Using DAIKIN Japan or the United States COPELAND high quality compressor, safety peaceful, durable power more low 13. The scroll compressor combination, the system can automatically implement the new generation capacity control 14. Schmidt microcomputer control system based on actual production needs, can accurately It controls the water temperature + 5 ℃ ~ + 35 ℃ unique double condenser and evaporator shell and tube design, heat transfer effect is very obvious 15 has various security devices, failure death occurs, then send a signal and display error code 16. widely used in rubber, plastics, extrusion, electronics, chemicals, food, medicine, central air conditioning and many other fields
