<p class="MsoNormal"><span style="color:black">Dear users,<br>
<br>
I have to set the air flow rate of the heat pump. The pump works all year in both heating and cooling modes. I calculate the flow rate from the maximum hourly load that I have in my load profile, but having two different max values for heating and cooling i
have two different air flow rate. So I would like to set the air flow rate to change when the system switches from heating to cooling.<br>
I think to use type Equa to link the 2 flow retes with a proportional factor and to regulate the heat pump by the thermostat fan control signal. My issue is how to do this in the right way.<br>
In my simulation i’m using the following types: <o:p></o:p></span></p>
