Study On Ecological Building Phase Change Heat Storage Ventilation And Control System

As the fossil energy reducing, energy problem has become a worldwide problem. Natural ventilation of solar energy technology developed all over the world. Because the solar energy cannot be make full use of, the phase change heat storage material is used to ventilation. In order to make the indoor heat environment conform to the requirements of the thermal comfort of human body, temperature and humidity control system is proposed.In this paper, ecological building model is built, the heat transfer behavior of ecological building is analyzed, a common room compared with ecological building established. Minimum indoor temperature of ecological buildings with phase change heat storage ventilation compared with the ordinary building increased 2.1 ?, and the highest temperature decreased 2.3 ?, the temperature fluctuation is reduced. The reason for the air enthalpy change of phase change heat storage room is less than the ordinary building, the phase change materials of phase change heat storage room will indoor air enthalpy value stored in the phase change latent heat of itself, so the phase change heat storage room air enthalpy change small, 2184 k J of two rooms enthalpy change of day and night difference as the function of the phase change heat storage material in a day. Phase change heat storage material will absorb solar radiation stored during the day, phase change and release the heat at night, make the room temperature is higher than the outdoor temperature, as a result of the indoor and outdoor temperature difference and pressure difference produced thermal pressure ventilation, and the natural ventilation is not affected by the external environment at night, can improve indoor air quality. According to the hot wet environment humidification or dehumidification, to conform to the requirements of the thermal comfort of human body, and design a control system that can be adjusted according to the change of environmental temperature, humidity, temperature and humidity inside the building, the indoor relative humidity stability between 30% and 80%, which accordance with the requirements of the thermal comfort of human body.Established in this paper, the ecological architecture model to the study of ecological architecture, the thermal comfort of human body, and the contribution of energy conservation and environmental protection has a reference.
