 The Central Air - Conditioning Water System in Skyscraper Building

In modern cities, more and more skyscrapers are built for commercial and residential uses. Air conditioning system for those building is quite common. However as the total height of the super high-rise building exceed 100m, the water and static electricity pressure subjected to pipelines of the air conditioning system is also below the conventional building. In particular, the lower part of the building's water electrostatic pressure will be greater than the maximum pressure capacity of copper tube bundles in the air treatment equipments and tube bundles in the hot and cold water host even.

Closed cooling water system

In the air conditioning project (especially large central air conditioning project), the use of closed cooling water system has great benefits. Open cooling water system is simple and practical, low cost, but there are some problems such as poor water quality, cooling water seriously polluted, microbial reproduction and other issues. These further result in corrosion and scaling within the system, affect use efficiency and shorten the unit and pipeline life cycle.

As a result of the use of plate heat exchanger, you can get a very small heat transfer temperature difference. If use low-quality cooling water such as river water or seawater, it is quite appropriate to use a plate heat exchanger. Most of the plates are made of alloy steel or soft metal, which has only increased the cost compared with stainless steel. This type of cooling water system has been widely used abroad.
