How to use semi-hermetic refrigeration compressor to save energy
The increasing population has made the problem of scarcity of resources increasingly serious, especially some non-renewable resources, which have become the focus of the struggle between countries. The semi-hermetic refrigeration compressor is a necessary facility for cold storage. It mainly uses electricity. In order to be more energy-saving and environmentally friendly, what methods can consumers take?
1. The principle of energy saving for refrigerators: increase the evaporation temperature and reduce the condensation temperature. On the premise of meeting equipment safety and production requirements, try to increase the evaporation temperature and reduce the condensation temperature. For this reason, the cooling tower has been modified to ensure the efficiency of cooling water.
2. Prevent and reduce pipeline fouling to improve the heat exchange efficiency of the condenser and evaporator. If the water treatment is not done well, the calcium carbonate and magnesium carbonate produced by the heating of calcium bicarbonate and magnesium bicarbonate will be deposited on the pipeline. The thermal conductivity is reduced, the heat exchange efficiency of the condenser and the evaporator is affected, and the electricity cost of the equipment is greatly increased. At this time, in addition to the use of water treatment technology, it is also possible to use regular automatic cleaning equipment for pipeline cleaning.
3, adjust the reasonable operating load of the refrigerator equipment
In the case of ensuring the safe operation of the equipment, the cooling host runs at 70%-80% load than when it runs at 100% load, the power consumption per unit of cooling capacity is smaller. Using this method to start up should be combined with the comprehensive consideration of the operation of the water pump and cooling tower.
4. Adopt the refrigerator frequency conversion device to adjust the speed of the centrifugal refrigerator compressor. After the low pressure refrigerant passes through the centrifuge, the pressure increases. The higher the speed of the centrifuge, the higher the pressure rise. In actual operation, most of the equipment is running under full load. A centrifuge with a fixed speed causes a waste of energy when the equipment is running at a small load. The frequency conversion centrifugal refrigerator can automatically adjust the compressor speed according to the change of load, and the energy saving space is relatively large.
The prices of cold storage refrigeration equipment given by refrigeration unit
manufacturers are very reasonable and affordable, and they are also strengthening energy-saving improvements. Consumers can use the above methods to test and improve during daily use, so as to make the use of refrigeration units more Convenient and energy saving.
