Feb 17, 2019 · The building’s MUA unit is generally located at the top of the building, either in the mechanical room or on the roof. The function of the MUA unit is in its name: it makes up the air that gets exhausted from kitchen, bathroom, and dryer exhaust systems. By replenishing the removed air, the MUA unit helps maintain balanced airflow in the ...
Mar 20, 2024 · Make up air units help reduce cold drafts, which can cause discomfort to occupants and increase heating and energy costs. Additionally, they eliminate high pressure differentials that make doors difficult to open or close, potentially causing injuries and safety hazards for workers . When considering a make up air conditioning unit, it is ...

Feb 22, 2019 · Clothes dryer: 100 to 225 cfm. Range hood exhaust fan: 100 cfm to 1,400 cfm. Common sense tells us that if a fan is expelling 100 cubic feet of air per minute from your house, then an equal volume of air (“makeup air”) must be leaking into your house at the same time to replace the exhausted air. If your house is old and leaky, the makeup ...
Apr 11, 2024 · Brett Singer, an indoor air quality researcher at Lawrence Berkeley National Lab, says 250 cfm should be enough. Of course, that depends on hood design, location, and capture efficiency. But just put the range against the wall and have a hood that covers the whole thing. With that setup, a 250 cfm range hood should suffice.
A makeup air unit (MAU) is an air handler that conditions 100% outside air. Typically used in industrial or commercial settings, or in “once-through” (blower sections that only blow air one-way into the building), “ low flow ” (air handling systems that blow air at a low flow rate), or “primary-secondary” (air handling systems that ...

The energy usage calculations are based on a 10,000 cfm (4700 L/s) MUA unit in Chicago. The cost3 of gas is $0.79/therm and electricity is $0.10 kWh. The carbon dioxide (CO2) equivalent conversion4 for natural gas is 0.510 CO2e lb/kWh (0.232 kg/kWh) and for electricity is 1.670 CO2e lb/kWh (0.758 kg/kWh). Calculations are based on 24/7 operation.
