Method for controlling cooling tower and cooling tower therewith

Abstract

The invention discloses a cooling control method for a cooling tower of a multi-host air-conditioning system and a cooling tower of a multi-host air-conditioning system using the method. The water supply pipes and return pipes of multiple cooling towers connected in parallel to the tower body are connected in parallel The water supply main pipe and the return water main pipe are formed, and the hot water from the water supply main pipe is evenly distributed to each cooling tower to effectively use the heat dissipation area of ​​the cooling tower and improve the heat dissipation efficiency; by detecting the return water temperature of the cooling tower return water main pipe, according to the return water The temperature is compared with the set value to control the start and stop of the fan and the number of openings. When the air conditioning system is under partial load, it can not only ensure the cooling effect but also effectively save energy.

Description

technical field [0001] The invention relates to a cooling control method for a cooling tower of a multi-host air-conditioning system and a cooling tower of a multi-host air-conditioning system using the control method. Background technique [0002] When designing a traditional multi-host air conditioning system, a one-to-one cooling method is adopted according to the cooling requirements of each host with different power. This design scheme also has the problems of complex engineering, large space occupation and high cost when multiple hosts share one riser circuit. In so many cooling systems, when the system is at partial load, the advantages of the large cooling tower cooling area cannot be used, and when the outdoor working conditions change, the number of cooling fans cannot be started and stopped according to different requirements, resulting in unreasonable Necessary energy loss and uneven loss of equipment. Contents of the invention [0003] One object of the pres...
