Modeling of a New Design Solar Cooling System Collector for a Typical Building in Humid and Warm Region in North of Iran for Simulation

Solar air heater is a special solar collector that its working fluid is air. It is used for warming of inlet air in HVAC system, solar dryer and for regeneration of desiccant wheel in solar cooling system. In this paper, a new design of air heater collector is introduced and its mathematical model for heat transfer in collector elements like collector coating, absorber,… are derived. Then by simulation of this collector in Matlab software, the best dimension of collector is determined. The results are validated by experimental data. The behavior of this kind of collector is studied in humid and warm region in north of Iran. Carrier software is used for building thermal load calculation.
