Modelling free convection in a trombe wall
Renewable Energy, 1991Abstract In this paper, the convective laminar heat transfer between the channel surfaces of the Trombe wall and a modified version of the conventional Trombe wall have been investigated. Velocity profiles, temperature profiles, and pressure defect have been investigated for the conventional Trombe wall, when the temperature of the masonry wall is ...

Mixed Laminar Convection in Trombe Wall Channels
Journal of Solar Energy Engineering, 1988The two-dimensional, steady, combined forced and natural convection in a vertical channel is investigated for the laminar regime. To simulate the Trombe wall channel geometry properly, horizontal inlet and exit segments have been added to the vertical channel. The vertical walls of the channel are maintained at constant but different temperatures while

Abstract A theoretical computer model of a Trombe wall-room system is developed from first principles and empirical equations, such that the designer is free to change any of the variables, thus the wall-room properties can be changed to improve the performance. The effect of varying those properties is investigated. The model avoids the drawbacks of

Promotion of Trombe wall through demand-side management
Solar Energy, 2020Abstract The present paper explores the feasibility of developing a demand-side management (DSM) strategy with the purpose of making advantage of the shifted solar energy use of Trombe wall (TW) systems to the evening hours while both the electric utility and its customers enjoy economic benefits. In many countries the winter peak hours coincide with

Trombe walls with phase change materials: A review
Energy Storage, 2020AbstractSolar energy utilization for covering the heating loads of buildings is an innovative and clean way to reduce electricity consumption. A Trombe wall is a classical passive solar heating system used in buildings. Increasing the weights and volumes of Trombe walls can increase their heat storage capacities.

The aim of this research program is to complete the results which have been obtained throughout 3 years of study of the Trombe wall ventilated by fresh air. That completion should be achieved with the experimentation of a transparent Trombe wall and with the realization of a full range of industrialized modular units.

Transwall versus trombe wall: Relative performance studies
Energy Conversion and Management, 1987Abstract This paper compares the performance of two types of thermal storage wall, namely Transwall and Trombe wall. Both of them are located directly behind the south facing glazing of a wall. A Transwall is essentially a transparent modular wall. It consists of water in a container made of parallel glass walls and has a partially absorbing plate at

Natural convection and conduction in Trombe wall systems
International Journal of Heat and Mass Transfer, 1991Abstract The thermal performance of classical Trombe wall solar collector systems is studied numerically. It is assumed that the flow is laminar and two-dimensional, the glazing is isothermal and the solar heat absorbed by the wall is transferred to the air in the channel with a constant flux by natural convection and to the adjacent room by ...

Performance of trombe walls and roof pond systems
Applied Energy, 1981Abstract This paper describes an analysis of the periodic heat transfer through thermal storage walls and roof pond systems subjected to periodic solar radiation and atmospheric air on one side and in contact with room air at constant temperature (corresponding to air-conditioned rooms) on the other.
