Hello experts, i would like to ask if there is an option to change the actual temperature of outdoor air i supplied to the coil? Is there any options from HAP? Currently, hap assuming the outdoor temp from the weather as entering air temp of outdoor air.

Thank you


only way I could think is setting up DOAS system to precool the air to the temp that you want. What is the reason you want to do this ?


hi engggu, yes, there is option in the weather section, you can manually edit the ambient air condition.

Hi moideen, just in case it will also affect the wall and other thermal loads? Thank you


If you have a legal copy of the software, you are on subscription and their support can answer all questions.

If you don't have a legal copy, you should not get advice on any legitimate forum. There probably is something in the forum requirements you agreed to.

If you have a legal copy, and their support isn't helpful (doubtful), feel free to ask here. It just wasn't clear from your OP if you already contacted HAP support.


HI engggu, of course, when changing the design dry bulb temperature, changing the wall heat transmission respectively
