How to use semi-closed refrigeration compressor to save energy?

The increasing population has made the scarcity of resources increasingly serious, especially some non-renewable resources, which has become the focus of the tussle between countries. Semi-closed refrigeration compressor is a necessary facility for cold storage, mainly using electric energy, in order to be more energy saving and environmental protection, what ways can consumers take?

Energy saving method of centrifugal refrigerating machine

1. Refrigeration machine energy-saving principle: increase evaporation temperature, reduce condensation temperature. On the premise of meeting the requirements of equipment safety and production, the evaporation temperature and the condensation temperature should be raised as much as possible. Therefore, the transformation of cooling tower is increased to ensure the efficiency of cooling water.

2. Prevent and reduce pipe scaling to improve the heat exchange efficiency of condenser and evaporator. Add water. If water treatment is not good, calcium carbonate and magnesium carbonate generated by heat will be deposited on the pipe. The thermal conductivity is reduced, the heat transfer efficiency of condenser and evaporator is affected, and the electricity cost of the equipment is greatly increased. In addition to water treatment technology, pipe cleaning can also be carried out by regular automatic cleaning equipment.

3. Adjust the proper operating load of the refrigerator

Under the condition of ensuring the safe operation of the equipment, the power consumption per unit cooling capacity of the refrigeration host is lower when it runs at 70%-80% load than when it runs at 100% load. Using this way to boot should be combined with the operation of the water pump, cooling tower comprehensive consideration.

4. The refrigerator frequency conversion device is used to adjust the speed of the centrifugal refrigerator compressor. After the low-pressure refrigerant passes through the centrifuge, the pressure rises. The more the centrifuge spins, the higher the pressure rises. In actual operation, the equipment is mostly running at less than full load. The centrifuge with fixed speed causes energy waste when the equipment is running under 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.

Refrigeration unit manufacturers give cold storage refrigeration equipment prices are very fair and affordable, but also to strengthen the improvement of energy saving, consumption in daily use can take the above ways to detect and improve, so as to make the use of refrigeration units more convenient and energy saving.
