Numerical Prediction of Airflow and Temperature Distribution in Large-Scale Agricultural PVC Greenhouse

Large-scale greenhouses are usually adopted to control the indoor climate conditions in agriculture. The envelope of agricultural greenhouses generally consists of a PVC (polyvinyl chloride) sheet, which produces a so-called greenhouse effect and protection from harmful insects. In winter, a supplementary heating device in greenhouses is needed because of the lower outdoor temperature and the non-uniform distribution of indoor temperature.

Year-round Energy Saving Potential for a Stratum Ventilated Subtropical Office

Stratum ventilation has been proposed to cope for elevated indoor temperature recommended by governments in East Asia. TRNSYS is used for computation of the space cooling load and system energy consumption. A typical Hong Kong office is investigated. Compared with mixing ventilation and displacement ventilation, stratum ventilation derives its energy saving potential largely from the following two factors: a reduced ventilation load and increased coefficients of performance (COP) for chillers.
