The Design of Central Air Conditioner and Purification System for Office Building
Abstract: The design of an office building in Shanghai central air conditioning system, through rational design, office building for staff to provide a good and comfortable working environment. The design by comparing VRV, VAV and fan coil plus fresh air system, the pros and cons, and ultimately determine the use of air fan coil system. Directly into the new indoor air and return air mixing. Fan coil cooling and heating load borne by each room. New air handling units set up on the roof, the use of multi-stage filtration combined photocatalytic air purifier program, to a certain extent to ensure the cleanliness of indoor air. By calculation, the total cooling load of the building in summer is 304kw, so use MAC1040BR cooled module units provide hot water for the central air conditioning system, sub-module units wide operating temperature range, hot and cold water supply is stable. Advantages of this system is that each terminal has a separate switch control, to ensure that each room can be independent temperature control, to prevent cross-contamination of the air. The design includes: determining air conditioning heating load calculation, air conditioning system, hot and cold source selection, the choice of fan coil arranged hydraulic calculation air system and water system, air system and water systems, indoor air the determination of the new air system air purification and so on.
