Product Details

Rooftop package unit

GRAD RTU has a very wide range of products from 3RT to 200RT cooling capacity, and the cooling only, heat pump type and constant temperature & humidity type are avaliable based on different applications.

The working principle of a rooftop package unit (RTU) involves a single, self-contained system that conditions air in one central location and distributes it through ductwork. The unit is typically mounted on the building's roof for efficiency and space-saving. It performs both cooling and heating functions through a combination of the vapor-compression refrigeration cycle and a heating module.

Core Components

A typical RTU is an "all-in-one" unit housing the following key components within a single cabinet:

Compressor: Compresses low-pressure refrigerant gas into high-pressure, high-temperature gas.

Condenser Coil and Fan: Releases heat from the hot refrigerant gas to the outdoors, turning it back into a liquid.

Evaporator Coil and Fan: The liquid refrigerant absorbs heat from the indoor air passed over the coil, cooling the air and turning the refrigerant back into a gas.

Expansion Valve/Metering Device: Regulates the flow of liquid refrigerant into the evaporator coil, reducing its pressure and temperature.

Heating Module: Depending on the unit type, this is typically electric heater or a heat pump reversing valve.

Filters: Clean the incoming return air before conditioning.

Blower/Supply Fan: Pushes the conditioned air through the supply ductwork into the building.

Return and Supply Air Openings: Connect to the building's ductwork system.
