<p>There are several models that can do evacuated tubes and a few that can do them with heat pipes. What information do you have available that you're hoping to use? Do you have a collector performance test? if so - is it OG300 or EN12975? This type of information will let us point to the specific model you can use.</p>

<div>Dear TRNSYS Users</div>
<p>Do you know which type of components defines heat pipe vacuum tube and direct flow vacuum tube (thermal collector)?</p>
<p>Because I need both of these models for my simulation!</p>
