An air-conditioning self-control method for improving the temperature and humidity uniformity of elevated warehouses in cigarette factories

Abstract

The invention relates to an air conditioner automatic-control method for improving the cigarette factory high rack storage temperature and humidity uniformity. The air conditioner automatic-control method is formed by a summer mode and a winter mode, and includes the steps of (1) arranging sensors to automatically detect the supply air temperature T<supply> and the high rack storage practical temperature T<aver>, wherein when the supply air temperature T<supply> is higher than the high rack storage practical temperature T<aver>, the air conditioner automatic-control method is in the winter mode, otherwise, the air conditioner automatic-control method is in the summer mode, and the relation between the air conditioning system load rate y<1> and the supply air volume x is y<1> = -0.1*x+1.1; and (2) arranging sensors to respectively detect the supply air volume of an upper-layer air pipe and the supply air volume of a lower-layer air pipe, and controlling the supply air volume of the upper-layer air pipe and the supply air volume of the lower-layer air pipe according to the relations between the upper-and-lower layer supply air proportions and the load rates in different seasons. According to the scheme of the air conditioner automatic-control method for improving the cigarette factory high rack storage temperature and humidity uniformity, the aims that the storage temperature and the storage humidity meet the design requirements, and the temperature and the humidity of the upper layer and the lower layer of a storage area are uniform are achieved; on the basis, the storage ventilation rate is reduced, and air supplying energy consumption of an air conditioner is reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a temperature and humidity method for an elevated warehouse in a cigarette factory. Background technique [0002] The elevated warehouse space of cigarette enterprises is relatively tall, generally about 24m. In air-conditioning design, the indoor environment is required to be stable, the temperature and humidity control precision is high, and the temperature and humidity gradient is small. According to the survey, in the actual operation of most cigarette enterprises at present, the temperature and humidity distribution uniformity of the air-conditioning in the elevated warehouse is relatively prominent, and the temperature and humidity in the warehouse are quite different from the design value. The main reason for the analysis is that the design of the airflow organization of the elevated warehouse is unreasonable, and the matching air-conditioning...

Problems solved by technology

The main reason is that the design of the airflow organization of the elevated warehouse is unreasonable, and the matching air-conditioning automatic control system is difficult to meet the design requirements despite its advanced technology

In addition, the automatic control scheme of the air conditioner often ignores the characteristic that the air conditioner operates under partial load most of the time, and only sets the automatic control scheme according to the design working conditions; moreover, the automatic control design does not take into account the different loads of the upper and lower spaces of the elevated warehouse. If the air supply volume is also different, the upper and lower air ducts operate at the same air volume throughout the year
