Nowadays, with the rapid development of science and technology, the level of industrial and agricultural production has improved, and the cultural life of the people has improved, the application of air conditioning in China has become more widespread, and the energy consumption of chillers has become larger and larger. How to save energy in the operation, operation and management of the chiller system is a major issue facing the people engaged in this work. So, which methods can make the chiller more energy efficient?

 Which methods can make the chiller more energy efficient? To make the chiller chiller work energy-saving, the operator should understand the working principle of the unit and the entire chiller system and the operating procedures to adapt to the characteristics of the unit. Strictly operate according to the instruction manual of the chiller to ensure the safe operation of the unit.

1. It is necessary to reduce the condensing temperature to meet the equipment safety and production requirements, to increase the evaporation temperature and reduce the condensation temperature. For this reason, the cooling tower is modified to ensure the cooling water efficiency.

2. It is necessary to use the chiller frequency conversion device to adjust the speed of the centrifugal chiller compressor. After the low pressure refrigerant passes through the centrifuge, the pressure rises. The higher the speed of the centrifuge, the higher the pressure rises. In actual operation, most of the equipment is running at a non-full load.

3. It is necessary to adjust the reasonable running load of the chiller equipment. In the case of ensuring the safe operation of the equipment, the cooling main engine runs at 70%-80% load ratio and runs at 100% load, the power consumption per unit of cooling capacity is smaller. The mode is to be combined with the operation of the pump and cooling tower.

4. It is necessary to prevent and reduce pipe fouling to improve the heat exchange efficiency between the condenser and the evaporator. If the water treatment is not good, the calcium carbonate and magnesium carbonate produced by the heating of calcium bicarbonate and magnesium bicarbonate will deposit. On the pipe. Decreasing the thermal conductivity, affecting the heat exchange efficiency of the condenser and the evaporator, and greatly increasing the electricity cost of the equipment.
