Numerical Investigation of Thermal Performance of a Trombe Wall of a New Design with Glazing for Cold Climatic Conditions Therm. Eng. Pub Date : 2023-12-01
Abstract The paper is devoted to the problems arising in using a Trombe wall under cold climatic conditions. These walls have a considerable disadvantage in cold climates. After sunrise, the solar energy falls on a Trombe wall through the air and heats up the air in it very quickly. This results in insufficient heat storage in the Trombe wall and an increase in thermal energy losses to the ambient
