Research on the Application of Independent Temperature and Humidity Control Air Conditioning Scheme in Office Project
A survey of existing projects showed that most office projects adopt the traditional cooling and dehumidification method of heat and humidity coupling to handle indoor cooling loads,which requires a cold source to provide chilled water at about 7℃ all year round.The energy efficiency of the host is relatively low and condensate water is easy to breed bacteria in the process of air treatment at the terminal units of the air-conditioning system.Therefore,from the perspective of energy saving,carbon reduction and health,it is necessary to find a better technical solution.This paper compared the heat and humidity treatment processes of different systems and their respective advantages and disadvantages,including the use of traditional air conditioning with dry fan coil unit system,the active cold beam system,the cold radiation ceiling system and all-air variable air volume composite dry fan coil system.In combination with the case of an office project,this paper analyzed and calculated the specific independent temperature and humidity control scheme.The energy efficiency of the system can reach approximately 6.2.The optimized cold source scheme utilizes a high temperature chiller to bear indoor loads and precool fresh air,with a load bearing ratio of up to 73.5％.
