<div>Dear Nidal Abdalla,</div>
<div> </div>
<div>I have used Type539 (Glazed Flat Plate Solar Collector from TESS Solar Library) with success for a solar air collector. Since the solar air collector was here in the states, they had the SRCC rating numbers for the efficiency and IAM's, so I could simply enter those numbers into the parameters of Type539. Since this solar collector model and many others in TRNSYS assume a constant fluid specific heat, you can implement solar air heating simulations with them.</div>

<div>Best regards,</div>

<div>Dear all</div>
<div> </div>
<div>I am trying to simulate glazed air collector for space heating using TRNSYS 17 with TESS libraries. Anyone can recommend the best choice for collector type can be used? I found at the TRNSY archives 2010 that Mr. David had mentioned that there are a number of air-based solar collectors available in the TESS Solar Component. In fact, I found only unglazed air collector in the TESS lib. I am wondering if someone can help me.</div>
