Constant-temperature and constant-humidity intelligent control system and method for industrial central air conditioner

Abstract

The invention discloses a constant-temperature and constant-humidity intelligent control system of an industrial central air conditioner. The constant-temperature and constant-humidity intelligent control system comprises the central air conditioner, a humidifier, an air supply channel and a control system body. The control system body comprises a temperature control assembly, a humidity control assembly and a flow adjusting valve. A plurality of temperature sensors and humidity sensors are arranged in a room, and the average temperature in the room is obtained through a sampling method, so that the difference of the detected temperatures in the room is small; and meanwhile, the temperature in the room can be accurately controlled by controlling the flow of an air inlet, and meanwhile, gasis intermittently inflated, so that the service life of the central air conditioner can be prolonged.

Problems solved by technology

[0002] When the product is produced in the factory, the product needs to ensure a certain temperature and humidity during production (such as the manufacture of medicines). When there is a large difference between the indoor temperature and humidity and the set temperature and humidity, it will affect the product. quality; the current factories generally use central air-conditioning to control temperature and humidity, but due to the large size of the factory room, there are differences in temperature and humidity in the room. The current central air-conditioning control method is mainly in the central air-conditioning Generate a gas with the same temperature and humidity as the set temperature and humidity, and then pass the gas into the room to achieve constant temperature and constant pressure control in the room. This will cause the central air conditioner to work continuously, which will shorten the service life of the central air conditioner. At the same time, the gas discharged from the central air conditioner will be affected by the outside world, which will lead to a certain deviation in the temperature and humidity of the gas sent to the room;

[0003] The current central air conditioner also has the ability to control the temperature and humidity in the room through temperature and humidity sensors. This control method is only suitable for rooms with small spaces. In rooms with large spaces, the difference in temperature and humidity is large. , a single temperature and humidity sensor cannot monitor the average temperature in the room, and cannot achieve intelligent regulation; secondly, most of the current factories are made of iron sheets. Due to the high heat transfer rate of iron, it is easy to control the temperature and humidity in the room. (The difference between indoor and indoor temperature is large, and the moisture condenses and adheres to the wall) constitutes an impact, which will affect the quality of the product

[0004] In the current central air-conditioning room, there will be temperature differences when the temperature is adjusted. There is no air circulation device in the current room, which will affect the quality of the product.
