Hydronic Systems Provide Better Energy Efficiency

By Greg Cunniff, Taco’s Applications Engineering Manager

Today’s HVAC industry offers a number of choices when it comes to providing heating and cooling in a large building: the three basic methods to provide comfort and move Btu around a building are by using water, air or refrigerant.

In our next series, we’ll compare these types of comfort systems. We’ll start by examining the energy efficiency issues. ASHRAE building in Atlanta offers an interesting opportunity for systems performance comparison:

The energy consumption of any HVAC system is comprised of two components: equipment that generates heating or cooling and equipment that distributes it. The energy needed to generate heating and cooling commands the majority of energy consumption in an HVAC system, but the energy required for distribution is significant. It can take 40% of total electrical cooling energy demand to move Btu in an air system, 30% in refrigeration systems and 20% in hydronic systems.

The challenge of comparing the energy efficiency of HVAC systems always has been to take both the distribution and generation components into account while using the same set of test criteria.
