Ventilation installation with $50\%$ outdoor air and steam humidification

Given: $$

The installation consists of: mixing section, heater battery, steam humidifier and supply fan and exhaust fan.

Outdoor air proportion $=50\%$

Outdoor air condition $=-10\frac{C}{60}\%RH$

Supply air condition $=22\frac{C}{7}\frac{g}{k}g$

Moisture production $=0\mathrm{.}4\frac{g}{k}g($in the room due to people$)$

Heating of the supply air due to fan heat $($supply fan$)=1K$

Heating of the exhaust air due to the fan heat $($exhaust fan$)+$ lighting $=2K$
