Recently, the weather across the country has turned on the cooling mode, and it is getting colder every day! The operating status of the cooling equipment in factories, production lines, laboratories, and computer rooms should also be adjusted seasonally. The importance you attach to it often determines its operating costs. The following are the tips for saving energy in the operation of chillers compiled by Dannice, which can reduce energy consumption by about 30%. Let’s take a look!

First, make a operation plan.

Any industrial production must follow a reasonable and careful plan, and the chiller is no exception. Making an operation plan is beneficial to the chiller, like reduce power consumption, improve overall operating status, and avoid equipment damage. To formulate a plan, it is necessary to combine the actual needs of production to avoid overloading the system. Cooling equipment can be added to relieve production pressure. Making a chiller operation plan and implementing it will help save energy, more efficient than ordinary machine.

The second is to maintain your chiller regularly.

After a long time of operation, it is inevitable that there will be failures. It is beneficial to prolong the life of the equipment. Regular cleaning of pipes can reduce pipe blockage and fouling, and at the same time improve refrigeration efficiency. There are external water towers, which are easy to come into contact with external dust and impurities, which will affect the circulation of cooling water and increase energy consumption.

Third, ensure the voltage of your chiller normal at all times

Electric energy is currently the basic energy for the operation of all chiller equipment. The normal voltage and current is conducive to the stable operation of the chiller. If it is a low-voltage environment, in order to ensure operating efficiency, it will inevitably increase power consumption; and excessive voltage will easily damage the chiller.

The fourth is to create an environment suitable for the chillers

A chiller also needs a suitable working environment just like a human being, which is more conducive to improving lifespan expectancy and reducing energy consumption. For example, in coastal areas, if a typhoon disaster occurs suddenly, the chiller should be shut down in advance to reduce energy consumption, and it is also of safety.

Fifth, condensation temperature and evaporation temperature

When selecting the type of chiller, the condensation temperature should be appropriately reduced, the evaporation temperature should be increased, the heat exchange area should be increased, and the overall performance of the chiller should be improved.

Sixth, reduce the cooling water inlet temperature

According to research data analysis, the COP (coefficient of performance) of the chiller decreases by about 2.9% for every 1 degree increase in cooling water temperature, so the cooling water inlet temperature has a great influence on the performance of the chiller, and an appropriate increase in cooling water can reduce the inlet temperature. In addition, the condensation temperature can be reduced to achieve the goal of energy saving by transforming the old water tower.

Seventh, reasonably control the operating load.

Practice has shown that the chiller operates within the range of 70%-80%, which is more efficient and energy-saving than full-load operation. In actual operation, the chiller should be kept at the load in combination with the actual conditions of the refrigeration pump and the cooling tower. The state of 70%-80% can minimize the loss of cooling capacity.

Eighth, select mode equipment of automatic temperature adjustment

At present, there are two kinds of temperature adjustment devices for the operation of chillers, one is manual and the other is automatic. Through the automatic temperature adjustment and temperature control device, it can be combined with the PLC microcomputer module to automatically adjust the temperature, automatically adjust the cooling water pump and the chilled water pump, so as to precisely control the freezing temperature. Water volume; detect and control the state of the chiller, automatically adjust the energy, and save more energy.

The above are some practical ways to improve the efficiency of chillers and reduce power consumption, which can be briefly summarized into two aspects.
