Accuracy of simplified heating coil models based on manufacturer catalogue data

Autor: Fernando Dominguez-Muñoz, José J. Costa, C.R. Ruivo, Francisco Fernández-Hernández

Publikováno v: Thermal Science and Engineering Progress. 3:10-23

The overall thermal performance of a heating coil, typical of those used in air conditioning systems, is investigated by two models based on the classical e–NTU method. The first model, here taken as the reference model, is supported by detailed in

Simplified component model of heating and dry-cooling coils: Influence of altitude and of glycol concentration in the heat transfer fluid on the error prediction of the heat transfer rate

Autor: José J. Costa, C.R. Ruivo, Giovanni Angrisani

Publikováno v: Journal of Building Engineering. 6:39-53

An empirical model for predicting the thermal capacity of a coil operating in dry mode is investigated. It is based on the well-known e-NTU method. Thermal resistances are estimated by empirical correlations calibrated with manufacturer data by using

Prediction of the heat gain of external walls: An innovative approach for full-featured excitations based on the simplified method of Mackey-and-Wright

Autor: C.R. Ruivo, Daniel Cardoso Vaz

Publikováno v: Applied Energy. 155:378-392

Nowadays, simulation tools are available for calculating the thermal loads of multiple rooms of buildings, for given inputs. However, due to inaccuracies or uncertainties in some of the input data (e.g., thermal properties, air infiltrations flow rat

Influence of the rotation speed on the effectiveness parameters of a desiccant wheel: An assessment using experimental data and manufacturer software

Autor: Giovanni Angrisani, C.R. Ruivo, Francesco Minichiello

Publikováno v: Renewable Energy. 76:484-493

The effectiveness parameters of desiccant wheels depend on the variable operating conditions. Experimental data measured in an air handling unit equipped with a desiccant wheel and data provided by the manufacturer software are used in the present wo
