Embodiment Construction
[0047] In order to make the objects, technical solutions, and advantages of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not to limit the scope of the invention. Further, in the following description, a description of the well-known structure and techniques is omitted to avoid unnecessary obscuring the concepts of the present invention.
[0048] The present invention provides a combination of the control system and the air-cooled pre-cooling air conditioning unit for noise reduction, comprising a pre-cooling apparatus 4, the noise reduction board 3, noise monitoring module, monitoring module temperature, water flow control module, control module, and the air volume control module.

The invention relates to a control system, method and application for noise reduction and precooling of an air-cooled air conditioner external unit. The air conditioner external unit precooling device cools the wind entering the air conditioner external unit through latent heat cooling; When the noise data of the air conditioner is higher than the upper limit of the noise threshold, reduce the air intake of the external unit of the air conditioner and increase the water intake of the pre-cooling device of the external air conditioner; when it is lower than the lower limit of the noise threshold, increase the air intake of the external unit of the air conditioner and reduce The water intake of the pre-cooling device of the external unit of the small air conditioner. The invention makes the air conditioner run stably, the noise reaches the standard through the combined adjustment of the air intake volume and the water intake volume, and there is no high temperature alarm of the air conditioner compressor, high control precision, low cost, high reliability and remarkable effect. The invention detects the noise of the external unit of the air conditioner. When the noise of the external unit of the air conditioner is higher than the upper threshold, the air intake of the external unit of the air conditioner is reduced. In order to meet sufficient cooling capacity, the water intake of the pre-cooling device of the external unit of the air conditioner is increased at the same time, while ensuring the cooling capacity of the air conditioner. Reduced the noise of the air conditioner.
Description
Technical field [0001] The present invention relates to a computer room air conditioning technology, and particularly relates to a control system for air-cooled air conditioning unit for pre-cooling and noise reduction, and application method. Background technique [0002] China's growth engine room far more than expected, my country's total of about 430,000 various types of rooms that can accommodate server over 5 million units. Wherein the operating nearly room, an area of about 90 square meters, the number of the cabinet of about 177,000, the server can accommodate approximately 200 million units. With the rapid development of cloud computing, the past five years, my country's demand for room traffic handling capacity will increase by 7 to 10 times, room area needs to double in order to meet the needs of the development of cloud computing. Our room total power consumption of 700 kwh, has accounted for 1.5% of total electricity consumption, the equivalent of Tianjin's total a...
