Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning energy saving, and in particular to a method for recycling condensed water of a base station air conditioning. Background Art

[0002] With the rapid development and widespread application of 5G communication technology, 5G base stations, as key nodes of the communication network, are crucial to ensuring the quality of communication and user experience. However, in the actual operation and maintenance of 5G base stations, the increase in air conditioning energy consumption has become an issue that cannot be ignored. In existing 5G base stations, the air conditioning system is mainly used to maintain the operating temperature of the equipment to ensure that the electronic equipment can operate under optimal conditions. However, due to the high power output and dense equipment layout of 5G base stations, the load on the air conditioning system is very large, especially during the high temperature period in summer, the energy consumption of air conditioning will increase significantly. This not only increases operating costs, but also has a negative impact on the environment.

[0003] To solve this problem, some studies have proposed using condensate recovery systems to reduce air conditioning energy consumption. These systems collect condensate generated during air conditioning operation and spray it onto the condenser fins to cool the condenser fins, thereby reducing air conditioning energy consumption. However, the condensate recovery systems currently used usually spray water onto the condenser fins in a steady flow, which has some problems. First, the steady flow water spraying method cannot adjust the spraying amount according to actual needs. When heat dissipation is required, if the spraying amount is insufficient, the temperature of the condenser fins will not be effectively reduced; and when heat dissipation is not required, if spraying continues, it will cause a waste of water resources. Secondly, the steady flow water spraying method is likely to cause excessive water accumulation on the condenser fins, affecting the heat dissipation effect.

[0004] Therefore, a condensate water recovery and utilization control method is needed that can dynamically adjust the spraying amount according to actual needs to improve the energy efficiency ratio of the 5G base station air-conditioning system. Summary of the invention
