Measurement of the heat transfer coefficient for walls
Abstract A test set-up was developed for the determination of the external heat transfer coefficient of walls under actual outdoor conditions. The set-up was used to measure the convective heatExpand
Effect of rain on the heat gain through building walls in tropical climates
Abstract A study was carried out to investigate the heat and moisture transfer through porous building watts exposed to outdoor weather conditions including rain. A mathematical model which canExpand
Simplified models for coupled heat and mass transfer in falling-film absorbers
A linearized coupled model is developed for the heat and mass transfer in falling-film absorbers. Its accuracy is established by comparing the predictions with those of a non-linear model and aExpand
Evaluation of heat and mass transfer coefficients for falling-films on tubular absorbers
Abstract A coupled heat and mass transfer model is developed to extract the transfer coefficients for falling-films from the measurements on a tubular absorber. The mass transfer coefficientsExpand
Accounting for rain effects in building energy estimation
We demonstrate a methodology to account for rain effects on wall heat gain using the DOE-2 building energy estimation software as a reference. The methodology involves modifying the boundaryExpand
Study of a compact spiral-coil cooling and dehumidifying heat exchanger
A spiral-coil heat exchanger consisting of a number of horizontal layers of spirally wound, finned tubes connected to vertical manifolds at the inner and outermost turns of each coil has beenExpand
Performance study of a falling-film absorber with a film-inverting configuration
This paper describes the development of a novel film-inverting design concept for falling-film absorbers. The solid surface of the absorber is segmented so that both surfaces of the falling-film areExpand
Performance of a compact, spiral coil heat exchanger
A spiral coil heat exchanger consists of a number of horizontal layers of spirally wound, finned tubes connected to vertical manifolds at the inner and outermost turns of each coil. This design hasExpand
The effectiveness of a spiral coil heat exchanger
An expression has been obtained for the effectiveness of a spiral coil heat exchanger (SCHE) which consists of a number of horizontal layers of spirally wound finned tubes. An experimental SCHE hasExpand
Heat and mass transfer effectiveness and correlations for counter-flow absorbers
A simplified linear coupled heat and mass transfer model for counter-flow absorbers is validated by comparing its predictions with those of a numerical turbulent flow model. The simplified modelExpand
