Principle and Introduction of Central Air Conditioning Cooli

The inlet temperature of cooling water should generally not exceed 32 ℃, and cooling water mainly refers to the water used for condenser and compressor cooling. Many users may not be very familiar with the issues related to the central air conditioning water system. Below is an introduction to the central air conditioning cooling water system brought by the editor of Shenzhen Bondrui manufacturer.  

（1） Direct flow cooling water system

The simplest cooling water system is a direct flow water supply system, which means that the heated cooling return water is directly discharged and not recycled. This system is only applicable to areas with particularly sufficient water supply, such as places close to rivers, lakes, seas, etc., and urban tap water is not suitable.  

（2） Circulating cooling water system 1. Natural ventilation cooling circulation system 2. Absorption chiller cooling circulation system

Advantages: Reasonable traffic allocation, minimal mutual influence between units, and high operational reliability. Disadvantages: The layout of piping and pipelines is the most complex, with a large number of pipelines, occupying a lot of space, and various equipment cannot be used as backup for each other.   

Advantages: The supply and return water adopt a centralized main pipe form, with fewer pipelines and less space occupation. Equipment can be mutually backed up, and the energy consumption of centrifugal chillers can be reduced by controlling the number or speed of cooling fans when the refrigeration unit is partially loaded. Therefore, it is the most widely used.  

In both dry pipe and hybrid systems, as cooling towers can be mutually backup,
