Uponor Solutions:
Commercial Radiant Heating and Cooling

Integrating Radiant Heating and Cooling with Traditional HVAC Systems

Uponor (formerly Wirsbo) was the first company to bring radiant floor heating to North America more than 40 years ago, and Uponor has more radiant cooling projects in service in North America than any other company.

As the leader in radiant heating and cooling systems, Uponor offers professionals the proven experience and expertise to offer unique advantages — including the ability to work with existing HVAC systems to conserve energy.

Radiant Cooling Design

A radiant cooling system should primarily be used where the system also will be used for heating during the colder months. It is important to design a radiant heating/cooling system to maximize the cooling capacity. 

Radiant cooling works best where wet bulb gain in the building can be controlled by the air-handling system. Radiant cooling does not address the latent or wet-bulb load in a building. A phase change is required to address this load. This is accomplished by the ventilation system of the building. The ventilation system will also control the balance of the sensible load throughout the occupied time of the day.

There are two types of radiant cooling systems — low mass and high mass. Low mass radiant systems circulate cool water in specialized panels or beams and typically operate during the occupied time. High-mass systems cool the building structure (slab, walls, ceilings) during unoccupied time and provide the additional advantage of off-peak cooling and further reduction in energy costs.
