Strengthen the operation management of equipment and establish a system of electricity consumption management and unit consumption statistics. It is convenient to assess the electricity consumption and material consumption quota, increase the necessary measuring instruments and instruments, carry out energy conservation and technical transformation work, and consolidate energy conservation work from the system.
1. Correctly control and adjust the liquid supply of the system, and avoid the phenomenon of excessive suction and overheating of the compressor.
2. Reasonably select the number of compressors to operate, so that the cooling capacity matches the thermal load of the system.
3. According to the process requirements and changes in outside temperature, properly adjust the number of fans and pumps.
4. Regularly drain oil, release air, defrost and remove scale, maintain good heat transfer effect of the equipment, avoid excessive condensation pressure and low evaporation pressure.
Improve the working conditions of refrigeration equipment as much as possible
1. Improve water quality, slow down scaling, increase condenser condensation, and reduce condensation temperature.
2. When the motor load ratio of the refrigeration equipment is below 0.4, the motor can be changed from â–³ to Y to increase the power factor, and the â–³ and Y connection can be automatically switched.
3. Try to use automatic control operation instead of manual operation, which can realize the operation of the refrigeration system under the best working condition, which can save 5-15%.
Through the above measures, we can solve some energy-saving problems of refrigeration units, which can solve the problem of refrigeration units.
