Efficient Organization of Air Exchange of Premises Using the Trombe-Michel Wall
Journal Title: Вентиляція, освітлення та теплогазопостачання - Year 2017, Vol 21, Issue
Abstract
Solar energy is a promising renewable energy source. One of the options for its use is passive solar heating devices. The use of the Trombe-Michel wall for heating the rooms is considered. The simplest variant is the organization of air exchange with the supply of heated air to the upper zone of the room. With this air supply scheme, overheating of the upper zone is observed. An option that minimizes such disadvantage is the installation of a fan that forcibly takes air from the upper zone and feeds it to the working zone. Because of the analytical evaluation of both variants, it was found that when air is supplied to the upper zone, 67 % of the solar energy is lost to overheating of the upper zone of the room. Moreover, the most effective solution, which gives a minimum overheating of the upper zone, is the use of a fan to induce air movement in the wall of Trombe-Michel. It is recommended to use solar heaters to heat the recirculation air of ventilation systems or supply the fan from solar energy
