Information

This components computes the heat flow balance between the heat flow from the supply ventilation and the exhaust assuming steady pressure balance thus steady mass flow balance.

Beacause of the thermal mode only, it assumes that the inlet mass flow rate is always equal to the outlet (the dynamic mass balance is reached generally much faster that the thermal balance). The exhaust temperature is the temperature at port_b and the supply at port_a.

The enthalpy flow balance to the volume that receive mass derives:

Where :

• H_flow is the enthalpy flow rate
• m_flow is the mass flow rate
• h is the specific enthalpy
• cp is the specific heat capacity
• T is the temperature

It is supposed that the specific heat capacity varies linearly with the temperature therefore the mean specific capacity is the specific capacity at the mean temperature.
