Evaporative cooling water and air conditioning system for frequency conversion machine room of power station

Abstract

The invention discloses an evaporative cooling water and air conditioning system for a frequency conversion machine room of a power station. The evaporative cooling water and air conditioning system for the frequency conversion machine room of the power station comprises a two-stage evaporative cooling cold air / cold water composite air conditioning unit, wherein a return air inlet of the two-stage evaporative cooling cold air / cold water composite air conditioning unit is connected with a first return air pipe, the first return air pipe is communicated with an exhaust duct and a second return air pipe respectively, the second return air pipe is communicated with the frequency conversion machine room, an air supply outlet of the two-stage evaporative cooling cold air / cold water composite air conditioning unit is communicated with a plurality of lower air supply outlets formed in a floor inside the frequency conversion machine room through an air supply pipe, and the two-stage evaporative cooling cold air / cold water composite air conditioning unit is connected with a dry type air blower coil arranged inside the frequency conversion machine room through a water pipe set. The evaporative cooling water and air conditioning system for the frequency conversion machine room of the power station can decrease the indoor temperature within a greater range, reduce cooling loads borne by an air system and reduce investment and energy consumption of an air conditioning air pipe system, and the energy conservation effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of air conditioning equipment, and in particular relates to an evaporative cooling water-air air conditioning system for a frequency conversion machine room of a power plant. Background technique [0002] The frequency conversion machine room of the power plant generates a lot of heat, and the proportion of sensible heat load is high. At present, most of them adopt the traditional mechanical ventilation cooling method. The temperature in the frequency conversion machine room of the power plant is high, which will easily reduce the working efficiency of the frequency conversion equipment and shorten its service life. Since most of the frequency conversion machine rooms use full-air air-conditioning systems, the air supply volume is large, the investment in air-conditioning duct systems and power equipment is high, and it takes up a lot of space. [0003] At present, indirect evaporative cooling equipment mai...
