The Utilization of Heat in Air Layer of a House

With the promotion of highly insulated and sealed houses, the central air conditioning systems that integrate ventilation, cooling and heating have received attention. In addition, solar heat utilization is attracting attention as an effective means to reduce energy consumption of cooling/heating and hot water supply. Therefore, research and development of houses combining the central air conditioning system and solar energy utilization are necessary for a comfortable thermal environment and energy saving. One of the easiest and cheapest methods of using solar energy is to add an air layer to the external walls. There are different types of external wall systems which contain air layers, such as the sunspace, double skin facade, Trombe wall, etc. In the book, we conducted an actual survey to understand the situation of heat utilization of the air channel and used numerical simulations to examine the effective method of heat utilization of the air channel.
