Due to various considerations, variable water volume type modular chiller equipment has appeared on the market. It is understood that this type of equipment is successfully developed on the basis of modular technology and combined with variable water control technology. So, how does its operation differ from a normal chiller?
Because the chilled water and cooling water flow control valves are installed in each modular unit of this new chiller, the working flow of the chiller and the refrigeration output of the compressor can be synchronously adjusted. In this way, not only the power consumption required for the operation of the chiller will be saved a lot, but it will also help the water pump to achieve the purpose of saving energy.
And because the variable water volume modular chiller itself can adapt to the variable water volume operation state, this is why the variable water volume work of the whole system can be realized by one pump, which solves the problem that the traditional chiller must use two The temperature at which the secondary pump can operate normally. When this type of unit is used, a proportional control valve or an on-off valve must be installed in the air handling unit on the load side, in order to ensure the variable water volume on the load side.
At the same time, the delivery cycle of cold water and cooling water is preferably completed by a variable frequency water pump, so as to obtain the maximum energy saving effect. Another point is to try to install the supply and return water pressure difference sensor on the most unfavorable loop to improve the operating efficiency of the chiller.
