technical field

The utility model relates to the field of air-conditioning system control, in particular to an air-conditioning system combined with hollow fiber membrane liquid dehumidification and evaporative cooling.

Background technique

With the rapid development of my country's economy, the demand for energy continues to increase. According to a report by Xinhua News Agency in December 2014, about 30% of my country's total social energy consumption comes from buildings, and half of building energy consumption comes from heating, ventilation, air conditioning and related systems. The proportion of energy consumption is about 15%. HVAC energy consumption is so high it cannot be ignored. In places with highly developed urbanization in my country, especially in "North, Shanghai, Guangzhou and Shenzhen" and cities such as Chongqing, Wuhan, Nanchang, and Nanjing, which are known as China's "Four Stoves", these cities have large population densities, developed industries, and severe high temperatures in summer. Affecting people's work and life, air-conditioning has naturally become a necessity in people's lives in summer, and in summer, the air-conditioning load can often reach 40% of the city's peak load, directly threatening the safety of electricity consumption in industrial production. Therefore, an energy-saving and environment-friendly utility model, especially an air-conditioning system that can utilize low-grade energy sources such as solar energy and industrial waste heat, has very large economic value. The commonly used air conditioner is a compression air conditioner. This kind of air conditioner consumes a lot of power. If the indoor air is updated, it will consume more power. Therefore, in order to improve the indoor air quality and reduce power consumption, an evaporative cooling system and a hollow fiber membrane liquid dehumidification system are introduced. . At present, evaporative cooling air conditioners are mainly used in the dry northern regions of our country, and they use the principle of water evaporation and heat absorption for cooling. Water has the ability to evaporate in the air, but once the water vapor in the air is saturated, the evaporation of water has reached a dynamic equilibrium. Therefore, in areas with relatively high air humidity, the outdoor humidity is relatively high, the difference between the partial pressure of water vapor on the water surface and the partial pressure of water vapor in the air is small, and the driving force of water evaporation is small. The use of evaporative cooling technology to reduce the air temperature is limited. limit. However, the outlet wind obtained by the evaporative cooling air conditioner contains a large amount of water vapor and has a high humidity. If this energy-saving air conditioner is to be promoted in humid areas, it is necessary to dehumidify the inlet fresh air of the evaporative cooling air conditioner fresh air unit and the outlet air discharged into the room. The dehumidification in most of the air conditioners currently used is accompanied by the cooling process, and this process will increase the energy consumption of the air conditioner. In order to make the air conditioner more energy-saving, scholars have done a lot of related research, so the temperature and humidity Independent control system, there are many methods of air dehumidification. In the current research, the hollow fiber membrane dehumidification technology is a dehumidification method with high dehumidification efficiency, energy saving and environmental protection. This dehumidification system can use low-grade energy such as solar energy and industrial waste heat. The regeneration of the dehumidification solution has the advantages of high liquid dehumidification efficiency, and at the same time overcomes the problem of dehumidification liquid entrainment. Combining the advantages of these two systems has great promotional value.

This process is an adiabatic process. During the humidification process, the air state changes along the isenthalpic line. In the direct evaporative cooling section 22, there are water spray chambers formed by the first spray nozzle 24, direct evaporative coolers and other adiabatic humidification equipment. The outdoor air enters the direct evaporative cooling section 22 after passing through the fresh air filter section 16, and after heat and moisture exchange with cold water in the contact heat exchanger, the temperature decreases and the moisture content increases.
