Modelling of the Ventilation Unit for A Stand Alone Solar Collector

摘要

The work described in this paper concerns a part of the modelling of a standalone air solar collector producing low temperature heat.The main role of the system is to avoid freezing temperatures and to reduce humidity in a room or in an unoccupied home during a long time,with only solar radiation.In view to dispose an essential sizing tool for this solar collector,we developed a mathematical model based on energy balance equations and on the characteristics of the system.This model allows simulation of the aerolic and thermal behaviour of the solar collector.It was validated using experimental data collected by telemetry in six operating sites.We present here the behaviour model of the ventilation unit part.
