How much vacuum in chiller?

The vacuum level of a chiller usually refers to the degree to which the pressure inside the refrigeration system is lower than atmospheric pressure. The normal vacuum range varies depending on the model, design, and specification of the chiller, but in general, the normal vacuum level of a chiller unit is usually between 10^-3 and 10^-5 Pa.

It is important to note that the vacuum level is essential for the proper operation of the chiller. If the vacuum level decreases, it can lead to a series of problems, such as a decrease in the output power of the compressor, a decrease in the refrigeration effect, an unbalanced compressor operating load due to gas backflow in the system, and an increase in current. Therefore, the vacuum level of the chiller needs to be checked and maintained regularly to ensure that it is within the normal range.

The above information is for reference only, if necessary, it is recommended to consult the relevant manuals or consult professional and technical personnel.
