Abstract

The invention discloses a temperature-humidity control device for a variable-air-volume air-conditioning system, and a temperature-humidity control method. The temperature-humidity control device comprises a combined air conditioner set, a variable-air-volume system controller and an indoor sensor. The control method comprises the following steps of: electrically connecting an indoor sensor and a built-in sensor to detect indoor humidity, indoor temperature, concentration of indoor CO2 (Carbon Dioxide), outlet air temperature at a humidifying section, outlet air temperature of a heat coil, and outlet air temperature of a cold coil; generating a control signal through the system controller based on detected information along with a series of operations; carrying out frequency-conversion regulation to a fan according to a control signal, and regulating opening of various built-in adjusting valves so as to ensure the constant indoor temperature and humidity as well as the air quality. The temperature-humidity control device and method have the benefits that: a decoupling control of the temperature and the humidity can be achieved, energy is saved, the capacity of resisting disturbance and the reaction speed and the control precision of the system are improved, and the constant indoor temperature and humidity can be kept as well as the air quality. The temperature-humidity control device and method can be widely applied to fields of precision machinery, instruments and meters, medicines and foods, textiles and tobaccos and the like.

Description

technical field [0001] The invention relates to the field of air conditioning control, in particular to a temperature and humidity control device and method for a variable air volume air conditioning system. Background technique [0002] Air-conditioning systems can be divided into comfort air-conditioning and technological air-conditioning according to their different service objects. Technological air conditioners are used to meet the production process or store items, or to maintain the best indoor conditions for indoor running machines and equipment. They are used in precision machinery processing, instrument manufacturing, medicine and food, textile industry, tobacco industry, etc. Therefore, technological air conditioners require high control precision of temperature and humidity. Comfortable air-conditioning is an air-conditioner that serves indoor personnel and aims to create a comfortable environment, such as air-conditioners used in residences, offices, hotels, sh...
