why choose lneya
We know that the low temperature chillers are complicated equipment. Even the switch process, if not according to the standard of operation or with no special maintenance, will inevitably lead to a decline in the refrigeration efficiency of the low temperature chillers and will greatly reduce the service life of the them. Here, we will talk about major attention matters when enterprises use low temperature chillers!

1. Refrigerant leakage

Refrigerant leakage will not only affect the refrigeration efficiency of low temperature chillers, but also affect the health of people in and out of the engine room, so the issue of refrigerant leakage must be noted.

2. Pay attention to the load of the low temperature chillers

The large load of low temperature chillers, or overload phenomenon which is more than the rated load, will bring about serious problems including refrigeration efficiency decline, bigger noise,  bigger vibration amplitude, excessive consumption of resources, decline in service life and so on which need to pay attention to!

3. Temperature and pressure

It can be said that the parameters related to temperature and pressure are the most important parameters of low temperature chillers. Enterprises should pay attention to the parameters related to the temperature and pressure of the low temperature chillers, and solve them in time, so as to avoid affecting the normal operation of the low temperature chillers.

Paying attention to the points mentioned above has extraordinary importance for extending the service life of low temperature chillers ,and improving the refrigeration efficiency and the use safety of low temperature chillers.
