Variable-working-condition air conditioning unit aiming at pollution concentration dynamic fluctuation and operation control method of variable-working-condition air conditioning unit

Abstract

The invention discloses a variable-working-condition air conditioning unit aiming at pollution concentration dynamic fluctuation. The variable-working-condition air conditioning unit comprises an airconditioning box. A new air inlet and a new air outlet are formed in the two ends of the air conditioning box correspondingly, the air conditioning box sequentially comprises a primary filtering section, a surface cooling section, a variable working condition section and an air outflow section in the new air flowing direction, the variable working condition section is composed of a low-resistanceair section and a deep purification air section, the deep purification air section is provided with a main filter, a particulate matter concentration sensor is arranged in front of the position of anair inlet of the variable working condition section, an air return port is formed in the primary filtering section corresponding to the air conditioning box, a first air valve is arranged at the position of the new air inlet, and a second air valve is arranged at the position of the air return port. By changing the structure of the air conditioning unit and the purification technological process,on the basis of achieving variable-working-condition operation of the air conditioning unit, biological aerosol probably bred by a surface cooler can be effectively filtered, the replacement frequencyof the main filter and the resistance of a whole system are effectively reduced, and the energy consumption and the maintenance cost of the system are effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of air treatment equipment, and in particular relates to an air conditioner unit with variable working conditions aimed at dynamic fluctuation of pollution concentration and an operation control method thereof. Background technique [0002] Aerosol pollution (including bioaerosols) of indoor air has attracted more and more attention. Traditional air-conditioning technology and equipment operate under fixed working conditions for air purification, which cannot adapt to the violent fluctuations in the concentration of outdoor particulate matter in Chinese cities throughout the year, nor can it cope with sudden outbreaks of epidemics. To ensure the purification effect when air pollution is serious or when an epidemic occurs, or the filtration system has high resistance, high energy consumption for system operation, and frequent filter replacement, resulting in high maintenance costs. [0003] In view of the ab...
