[0002] The heat dissipation problem of data centers has always been the focus of the refrigeration / cooling industry.

At present, the country vigorously advocates energy saving, and the cooling mode and system of data centers are also updated and iterated. Data centers can be described as "every inch of land is worth a lot of money". The most mainstream way is to cool the data center room through the liquid cooling system assisted by the mechanical refrigeration air cooling system. For this, it can be considered that two sets of systems are used to cool a data center at the same time.
