New sensing solutions from Sensata Technologies, a world-leading manufacturer of sensors for industrial applications, are helping designers of hydronic HVAC systems to provide the essential pressure and temperature controls for a successful system design.
A hydronic HVAC system utilises water as the primary fluid to transfer energy throughout the building. Water has outstanding heat transfer characteristics; to deliver heat, the system must have a heat source, such as a boiler, and to provide cooling, the system must have a cooling source, such as a chiller or cooling tower.
The heated or cooled water is pumped throughout the building to air handling units or terminal units (or other similar), where it transfers energy with air from the ventilation system before it recirculates to the heating or cooling source. The conditioned air is then delivered to the room.
