Presents the air conditioning design for a combined workshop of a cigarette factory in Shanghai, which adopts the temperature and humidity independent control concept, with the high temperature chilled water and low temperature chilled water respectively as cold source. Sets the outdoor air handling units separately. Firstly, uses the high-temperature chilled water for outdoor air pre-cooling. Secondly, uses the low-temperature chilled water for in-depth dehumidification. Thirdly, mixes the treated outdoor air with return air and cools with constant humidity, and then delivers to workshops. Therefore, the energy consumption caused by reheating in traditional air conditioning system is avoided. This system only needs adjusting and maintaining the treated outdoor air humidity and the mixed supplying air temperature to accurately control the humidity and temperature.
