Influence of building perimeter zone characteristics on design of VAV air conditioning systems

By establishing a model, the building shape is optimized to reduce the load of the envelope structure in the perimeter zone of the building. By setting different combination modes of the perimeter zone, a reasonable division of the cold and hot single duct VAV system in the perimeter zone is to be pursued. The relative relationship between the heat dissipation of the building envelope and solar radiation heat gain in winter as well as the probability of indoor overheating are also analysed. The measures to deal with and alleviate the indoor overheating of the cold and hot single duct VAV system in the perimeter zone are discussed.
