The invention discloses an evaporative cooling-mechanical refrigeration combination air conditioning unit provided with an automatic control system. The air conditioning unit comprises a unit shell, and a primary air inlet and a primary air supply outlet are formed in two opposite side walls of the unit shell respectively; the automatic control system and an evaporative cooling-mechanical refrigeration combination cooling system are arranged in the unit shell, and the automatic control system is connected with the evaporative cooling-mechanical refrigeration combination cooling system. According to the evaporative cooling-mechanical refrigeration combination air conditioning unit provided with the automatic control system, the accurate switchover among three operation modes in the evaporative cooling and mechanical refrigeration combination air conditioning unit is achieved through the automatic control system so that the air conditioning unit can be adapted to different environments.
Description
technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to an evaporative cooling-mechanical refrigeration combined air-conditioning unit with an automatic control system. Background technique [0002] At present, air-conditioning units combined with evaporative cooling and mechanical refrigeration mainly have the following three working modes, namely: combined mode of indirect evaporative cooling and mechanical refrigeration, combined mode of indirect evaporative cooling and direct evaporative cooling, and single direct evaporative cooling mode; The reasonable switching of the three working modes can realize the reasonable application in different seasons, especially in the transitional season, it can make full use of the natural cooling source and achieve the purpose of energy saving. [0003] Under the same dry bulb temperature, the same relative humidity, and different atmospheric pressure conditions, t...
