Analoge simulatie van warmte- en waterdamptransport in klimaatkamers voor planten en in de daarbij toegepaste luchtbehandelingsinstallaties - 1. Beschrijving en opzet
article
By means of an analog simulation method, investigations have been carried out into the heat and mass transfer in a phytotron and the air conditioning equipment serving it. The heat and water vapour transfer processes are simulated by means of analog network and computing circuits. At the nodes for the wet surfaces (leaves, cooling coils, humidifier) the network for the heat transport influences the network for the vapour transport through t-p converters. At these same nodes an opposite interaction occurs by the evaporation or condensation heat fluxes. The purpose of these investigations is the analysis of the stationary and dynamic behaviour of the climate room and the installation, under various circumstances related to the radiation level and day-night cycles, the (rather large) ranges of air temperature and humidity, and to the air conditioning systems being considered. Of interest are the performance of the various control systems in relation to the temperature and humidity fluctuations in the climate room, the difference in leaf temperature and the energy requirements of the air conditioning equipment.
