Danfoss 40 hp big blue compressor Today I will introduce to you Danfoss CH485 compressor, CH485 40 ton compressor is not only compact but also integrates many innovations. The CH485 compressor has the following characteristics in terms of protection level and improved efficiency: Built-in exhaust temperature protection Intermediate exhaust valve for higher energy efficiency
Built-in exhaust temperature protector
The built-in exhaust temperature protection of the compressor is more reliable than the temperature protection of the ordinary external installation. Due to the influence of ambient temperature, there is distortion. The built-in temperature sensor can directly detect the exhaust temperature of the compressor scroll is not affected by the ambient temperature. At the same time, the alarm delay time is short, the reliability is greatly improved, and the same protection circuit as the motor PTC protection string. Intermediate exhaust valve
The unique intermediate exhaust valve (IDV) is used to make the compressor adjust accordingly according to the different load and pressure conditions of the system. The intermediate exhaust valve (IDV) can reduce the excessive compression of the refrigerant under partial load, while keeping the cooling capacity unaffected. When the pressure ratio (partial load) drops below the optimized value built into the scroll, the valve opens, allowing the motor to adapt to system pressure conditions. This will reduce the motor work and motor energy consumption, thereby improving the seasonal energy efficiency of the system. Reduce the starting torque and the impact on the bearing and cross ring when starting, reduce the starting current Operating range

liquid 1. Liquid back: When the refrigerant returned to the compressor is not a pure gas state, but contains liquid, the influence of the liquid refrigerant on the compressor is negative. If there is too much liquid, it may even cause liquid shock, even if there is no liquid shock, it will happen. Wet compression causes oil to run away.
