In order to more clearly illustrate the technical solution of the utility model and advantage, with reference to the utility model embodiment The air-conditioning system of offer, exemplified by being radiated using system as shown in Figure 2 to data center, as shown in figure 4, can include Following each step：

Step 401, ON cycle water pump 14 and handpiece Water Chilling Units 3, and control the first control valve to open by controller 4.

Fig. 2 is refer to, unlatching is followed after bad water pump and handpiece Water Chilling Units, and handpiece Water Chilling Units can then be carried out to the cooling backwater of entrance It is cold in the first water return pipeline, the second water return pipeline and the 3rd water return pipeline is driven to follow bad water pump to form cooling water for refrigeration But while backwater enters handpiece Water Chilling Units by the first water return pipeline, the cooling water output formed in handpiece Water Chilling Units is driven.

Meanwhile first control valve open under the control of the controller after, the cooling water of handpiece Water Chilling Units output can be by the One water supply conduit is exported to the surface cooler of double low-temperature receiver fresh air conditioner-mechanicals.

In the utility model embodiment, the temperature of the cooling water of handpiece Water Chilling Units output can be not less than 14 DEG C, into cold water The temperature of cooling backwater in unit can be not less than 19 DEG C, and the trend of the temperature gap of the temperature of cooling water and cooling backwater It may range from 4 DEG C to 6 DEG C.The temperature of cooling water and the temperature of cooling backwater are of a relatively high, can reduce the energy consumption of handpiece Water Chilling Units.
