Three centrifuges are estimated to be Trane centrifuges, and two are 1 spare. This is the most common design. It is also very reliable to use. The energy efficiency ratio of the water cooler is also relatively high. If centrifuges need electricity, there are no other power-saving units except DC frequency conversion centrifuges and magnetic levitation centrifuges, but these two units are relatively expensive, both of which are emerging models, and their reliability and durability need to be verified.

But this configuration is not the most reasonable:

1 The standby cooling capacity of the standby machine is too large and expensive.

2. The number of units is small, so it can't track the load change well. It may cost more electricity in spring and autumn.

3. The maintenance of the unit is complicated, and it can only be repaired by the manufacturer, with high maintenance cost and long maintenance cycle.

Although the centrifuge is very reliable, it does not rule out the possibility of breaking two machines at the same time, and its reliability is average.

Screw machines can be used completely, especially modular screw machines, occupying no more space than centrifuges. For example, using 485KW 12 water-cooled screw greatly improves the reliability and the energy efficiency ratio is not lower than that of centrifuge.

The scheme of water cooler can perfectly solve the problem of cooling in summer, but heating in winter is more troublesome. Although there is central heating in Tangshan, at the beginning of heating, the water temperature of 38 degrees and the pressure of 3 kilograms of water delivery really made restaurant operators feel big. I don't know if it's an example, hehe, welcome to ask questions.
