Summary of common maintenance knowledge of chillers

The first is that the chiller is not “prone to problems”.

As a complex and sophisticated equipment, chillers can guarantee regular, reasonable, and scientific maintenance during the use process as long as they can guarantee their own quality most of the time.

Second, the high-pressure failure that often occurs in the chiller does not require “maintenance”.

High-pressure failure is a long-term failure of the chiller. The high-pressure problem of the chiller often occurs frequently. This does not mean that the chiller cannot operate normally. The chiller can operate normally under the high-pressure failure state and does not require maintenance. , The high-pressure failure of the chiller is often caused by the failure of regular or serious and scientific maintenance, which causes the condenser and evaporator to be dirty. It may also be caused by other problems of the chiller, but it can maintain normal operation. However, the cooling efficiency and cooling capacity of the chiller will decrease, and the load will increase.

The third is the arrival of winter. Some companies do not need to use chillers and need to “collect”.

Due to the gradual cooling of the weather and the arrival of winter, some companies may no longer need to use the chiller, but when not in use, they cannot leave it alone. Instead, the chiller should be cleaned under the premise of a long shutdown, especially It is necessary to clean up the cooling water and chilled water, thoroughly drain it, and cut off the power supply.

If necessary, special methods should be taken to keep the chiller main unit insulated, so as to avoid the failure to start normally during normal use in the coming year, and avoid damage to the chiller and other problems and malfunctions in winter.
