Hydro-Air Heating and Cooling Systems

Hydro-air systems use some elements of both hot water and hot air heating designs to create a heating system that can interface with central cooling in a very cost effective way. A typical system uses a single gas or oil fired boiler to produce the heat for the entire facility. The boiler delivers heat to air handlers equipped with in-line heating coil.s The ductwork from the air handler connects to conventional supply air diffusers and return air grills throughout the facility (or portion of the facility for multiple zone systems.)

The installation savings of this design come in when we add cooling to the facility. The air handlers that distribute the heat are also equipped with cooling coils so the distribution ductwork and air handler are utilized for both heating and cooling.

Design
When we prepare a design for the installation of a hydro-air system in your facility we base the equipment on the heat loss and heat gain of your facility. We do specific calculations in order to determine how much heat your facility absorbs each hour during the summer months, and how much heat your facility loses each hour during the winter months. The major factors, which determine the amount of heat gain and loss, are the size of your facility, the number and compass orientation of windows, and the amount of exposed roof area.

You choose a boiler based on the heating demands determined in the heat loss calculations. The number of air handlers used is based on your facility and where you desire separate zones.

Once we split up the zones, we size up the cooling equipment. Typically we'll provide you with an independent cooling system for each air handler or zone in your facility. The cooling capacity is based on the heat gain of the zone.

The quantity of heat gain is measured in BTUs - every 12,000 BTUs equals one ton of cooling. It is important that we install neither too much nor too little cooling. If the equipment is undersized for cooling, the facility will not be cold enough on hot days. If the equipment is oversized for cooling, the indoor air will not be properly dehumidified, and will feel cold and clammy.
