    Tips for energy saving in refrigeration systems

    Tips for energy saving in refrigeration systems Screw refrigeration compressor When setting the cooling capacity of the compressor, avoid the operating range of low energy efficiency ratio; for the refrigeration system with a large range of operating conditions, implement the automatic adjustment of the internal volume ratio; for the screw machine with economic zone operation, discuss the implementation of the economizer Automatic adjustment of operating conditions. Piston compressor The method of reducing the number of cylinders working in a compressor as an energy adjustment unit avoids the reactive operation of the piston and the operation of reducing the COP value of the compressor; frequency conversion technology is used to achieve energy stepless adjustment and energy saving in improving operating conditions. Adjustment of multiple units running online Try to use the number of compressors as the energy adjustment unit; try to make each compressor in a high energy efficiency ratio operating state; design a combination of different size Yasuo heads, and invest the corresponding energy combination for the needs of load changes. About frequency conversion adjustment Frequency conversion technology is one of the more popular methods for compressor energy regulation. If the frequency conversion is too low, it will cause the shortcomings of reduced oil pressure difference and oil volume; too high frequency conversion will increase the oil circulation and consumption, and will also increase the compressor valve failure. Variable frequency drive should also pay attention to the motor should be selected according to the maximum power. Real-time calculation control to ensure the best energy-saving operation of the system The optimal design of the refrigeration system and the optimal operation of the automatic control are very important to realize the energy saving of the cold storage. The real-time control tasks of energy-saving operation in cold storage can be completed by data collection, computer control and monitoring system. The data collection and calculation control system's collection objects are related parameters of the refrigeration device, the refrigeration system and the working environment. The categories include temperature, pressure, pressure difference, liquid level, current, operating status and fault conditions. Effectiveness of energy-saving automatic control operation of cold storage The use of electronic expansion valve can save energy by 10%; the defrosting function on demand can save energy by 5%; the storage temperature setting at night can be saved by 4%; the cooling fan operation control can save energy by 3%; Condensation control can save energy by 2%; compressor unit and condensing fan control can save energy by 10%. The comprehensive energy saving effect of the above 6 measures can reach 15% to 34%.
