on video Rooftop Units explained - RTU working principle hvac

 

The RTU is the most widely used commercial heating and the cooling unit found in the U.S. The rooftop unit is sometimes called a package unit, as all its components are contained in one unit.

The RTU is usually a direct-expansion (DX) unitary system, which means that the air is cooled by a refrigerant, and can be either fan-cooled or water-cooled. Heat is typically provided in a fuel-fired furnace or supplemental electrical coils housed inside the unit.

A typical RTU consists of:

an evaporator core, which absorbs heat;

a condenser, which releases heat;

a compressor (the motor compresses the refrigerant gas and changes it to a liquid under pressure);

a blower motor and fan;

a cooling motor and fan;

an intake for outside air;

a heat source (furnace); and

an exhaust flue.

The RTU connects to the building's return air and supply ducts.
