Hello Everyone ,

A Hotel has two HVAC Systems ,

System 1 : A Inlets with Air Supply of 18 °c .
System 2. A Cooling Concept has Multi Task of Sucking the Air ,Which has 26 ° C and again Recirculating a fresh air of the Temperature 20°C into the room .

The System 1 has Sucessfully Created but struggling in System 2 creation .So please any one explain me How to assign a object which has two Conditions ? As my Point of view Can i create one opening and one with inlet as same like i created in System 1 .Is it correct or please give me a suggestions .

Main Conditions : This both Systems are on the Floor .

Best Regards ,
kavin.

Hi,

I am not quite sure from your description what you are trying to achieve, but I have a couple of suggestions. If your system 2 consists of multiple inlets and outlets, you can link these together using the angled-in objects. You can link the exhaust air at 26 degC to an inlet at 20 degC, you can specify this as just a mass flow link so the flow remains consistent, but the temperature can change.

Otherwise you can specify an inlet and outlet with the same mass flow and different temperatures on different areas of a blockage object. You cannot specify one object to both be both an inlet and an outlet with different mass flows, as this doesn’t make physical sense.

Thanks,
Harry
