The pluses and minuses of water system central air-conditioning:
1.1: while due to main frame evaporation and cooling system, dispatching from the factory integral installation prepare, the efficiency of runtime host can guarantee, and can not change due to the length variation of pipeline the efficiency of main frame itself.
1.2: cost is relatively low.
1.3: loine pressure is low, and is longer than high-pressure system with respect to the life-span.
The defect of conventional central air-conditioning:
