The Information Center In Xi’an Humiture Independent Control Air-conditioning System Project Design And Realization

In this paper, the air conditioning system in Xi’an Information Center, for example, made a plan individually controlled air-conditioning system based on liquid desiccant and chilled beam air temperature and humidity design and implementation.This paper analyzes the conventional air conditioning system heat and moisture combined treatment of the presence of high energy consumption, comfort and low and poor air quality, combined with a high comfort customer requests, Xi’an Science and Technology Information Center, made a temperature and humidity independent control air-conditioning system program design. The system includes a humidity control system and temperature control systems, the two systems independently adjustable control the indoor temperature and humidity, thus avoiding the conventional air conditioning system, temperature and humidity combined treatment brings more energy waste and air quality and reduce the problem, but heat and moisture than the room to meet changing requirements, avoiding the indoor humidity is too high or too low phenomenon.Humidity control system, heat pump heat recovery type liquid desiccant air fresh air unit to take on new indoor latent heat load and load control indoor humidity.Temperature control system, the use of chilled beams indoor Information Center sensible heat terminal devices that end, in order to prevent condensation, summer heat chiller as cold source, its supply and return water temperature of 16/19 ℃.After the project is actually running, the air conditioning system is the actual operating results during the summer month of testing done. The test results show that, in most cases, the indoor temperature and humidity parameters meet the design requirements, high comfort. But a few days the end of the chilled beam appear condensation. Analysis of the possible causes condensation, and targeted suggestions for improvement, provide a reference for future applications based on liquid desiccant Xi’an and chilled beam air temperature and humidity independent control air-conditioning system design.Finally, pointed out the lack of prospects for a summary of the subject.
