How to Save the Electricity Consumption of the Chiller?
We all know that in the process of using a refrigerator, when the evaporation temperature and the compressor speed are the same, the lower the condensation temperature, the larger the cooling coefficient, and the smaller the power consumption. According to the effective statistics of our company, for every 1°C increase in the condensing temperature, the power consumption per unit of cooling capacity will increase by about 5%, so it is beneficial to keep the condensing temperature stable for the improvement of the cooling capacity.
1. Improve the heat release coefficient of the condenser:
It is practical and effective to improve the heat release coefficient of the condenser of industrial refrigerators, and the effective way to improve the heat release coefficient is to reduce the thermal resistance of the heat dissipation side, and to effectively reduce the resistance of the cooling system. For example, the water quality of the cooling water of the water-cooled chiller changes continuously during the cooling cycle, causing scaling, corrosion and blockage.
2. Treatment of cooling water:
At present, tap water is mostly used for cooling and replenishing water in general industrial refrigerators. For large-scale industrial refrigerator cooling water systems, only adding a small amount of high-quality tap water will not work, and the cooling water must be treated with medicine.
The piping arrangement of the cooling water system of the industrial refrigerator also has a certain influence on the cooling efficiency. Although the piping arrangement of industrial refrigerators is relatively simple, if the consideration is not thoughtful, there will be some unforeseen problems. The circulating cooling water system of most industrial refrigerators is an open system. If the volume of the water storage tank is small, the distance between the pipes is too long, or the resistance balance of the outlet pipe is seriously out of balance, the air will be mixed into the water, enter the water pump and be pressed into the pipe, causing Severe water hammer causes damage to the water pump outlet pipe and its fittings.
3. The piping arrangement of the cooling water system:
The cooling water system of the industrial chiller should pay attention to the balance of pipeline resistance, which is easy to adjust the flow and balance the flow. If the above control cannot be achieved, an automatic control system should be used. The inlet and outlet of the water circulation should be equipped with solenoid valves, which should be opened and closed synchronously. , or set a balance valve on the inlet and outlet pipes to ensure that the inlet water meets its rated flow. In order to increase the water collection capacity of the suction pipe, the diameter of the suction pipe can be appropriately increased when designing the suction pipe.
The above is a brief introduction to how to use industrial refrigeration to save electricity and reduce business costs. It is not difficult to see that in order to use a good industrial chiller to be more energy-efficient, in addition to the above measures, other comprehensive and beneficial means should also be adopted. LNEYA refrigeration manufacturer specializing in the manufacture of industrial chillers has concluded through long-term research that an industrial chiller with a reasonable structure and scientific layout can use appropriate methods of use, which can increase the use efficiency of general industrial chillers by about 20% to 30%. If the industrial chiller is used well, the normal industrial production efficiency will be multiplied with half the effort.
