Computer Simulation of Heating and Cooling of Ventilation Air for a Passive Solar House

摘要

A computer model was developed to analyze the performance of a proposed system for moderating the temperatures of ventilation air for a semi-buried passive solar house using a rock bed installed outside the insulation on the three buried walls of the house. The soil outside the rock bed would be covered with insulation to allow the soil to augment the thermal mass of the rock bed. The ventilation air would be warmed in winter by passing through the rock bed before entering the house. This would cool the rock bed and the soil adjacent to it. In summer, the intake air for daytime would be cooled by passing over the cooled rock bed. Cool nighttime air would be used to cool the thermal mass of the house and to backflush the rock bed. Thus the system takes advantage of both the annual and diurnal cycles. (ERA citation 04:036098)
