Rotating wheel type heat recovery evaporative cooling and mechanical refrigeration combined air conditioning unit

Abstract

The invention discloses a rotating wheel type heat recovery evaporative cooling and mechanical refrigeration combined air conditioning unit. The rotating wheel type heat recovery evaporative cooling and mechanical refrigeration combined air conditioning unit comprises a unit shell, wherein an upper air duct and a lower air duct which are distributed up and down are formed in the unit shell, an airoutlet a and an air outlet b are formed in the positions, corresponding to the two side walls of the unit shell, of the upper air duct correspondingly, an air inlet a and an air supply outlet are formed in the positions, corresponding to the two side walls of the unit shell, of the lower air duct correspondingly, a rotating wheel type heat recoverer, a vertical pipe indirect evaporative cooling unit, a mechanical refrigeration unit and a rotating wheel dehumidifier are sequentially arranged in the unit shell in the flowing direction of inlet air, a secondary air valve a and a secondary air valve b are arranged on the two sides of the vertical pipe indirect evaporative cooling unit correspondingly, and an air inlet b is formed in the top, corresponding to the mechanical refrigeration unit,of the unit shell. According to the rotating wheel type heat recovery evaporative cooling and the mechanical refrigeration combined air conditioning unit, the problems that when an evaporative cooling system or a mechanical refrigeration system is independently used, the cooling range is limited and energy consumption is large are solved, complementary advantages of evaporative cooling and mechanical refrigeration are achieved, and the energy efficiency ratio of the unit is fully increased.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and relates to an air-conditioning unit combined with a rotary heat recovery type evaporative cooling and mechanical refrigeration. Background technique [0002] With the rapid development of the economy and the continuous advancement of science and technology, people's living standards have also been qualitatively improved.
