Energy and comfort: A new type for TRNSYS

Two subroutines have been developed which permit users of the TRNSYS programme to calculate the parameters of ambiental comfort (PMV and PPD).The first subroutine deals with the calculation of the view factors inside a room for all the values of the spatial coordinates and, thus, permits the average radiant temperature to be calculated in every position. The second subroutine has been developed in accordance with the indications of the ISO 7730 standard.Both subroutines have been validated and then interfaced to TRNSYS.The integrated programme has been utilised to compare the performances of different heating systems in terms of energy consumption and comfort, maintaining the temperature of the interior constant for different climatic conditions.

Thermodynamic Analysis of Various Dehumidifying Dryers for Wood

Typical methods of dehumidification of air circulating in the dehumidifying driers (indirect and direct cooler and partial exchange of the air) were analysed. Energy aspect of cooler operation was evaluated. The method for minimization of unit thermal energy consumption in a dehumidifying drier by the optimal selection of the cooler point was also given. Methods of the heat recovery of heat conveyed in a cooler lending to save energy (heat regeneration. expansion and compression of the air, a dehumidifier) were analysed. It was indicated that introduction of dehumidifiers into contemporary wood driers caused significant improvement of energy aspects of their operation
