Geothermal heat exchangers almost always use condenser water or glycol as the heat transfer medium — and, sometimes, refrigerant. Wastewater heat recovery systems typically preheat domestic cold water ...

Chillers have typically been thought of as providing cold water to cooling coils located in a variety of air-handling systems throughout a building. However, there are certain building owners and ...

At Lawson Ice Arena, the heat generated at the evaporation coils of the arena's ice machine is transferred to water circulating through a closed-loop system. The heated water is sent to a heat ...

The 42,000-sq.ft. Davis Building's geothermal system supplies 58°F to 62°F closed circuit ground source water to ceiling-mounted, active chilled beams. Chilled beams reduce fan energy by up to 50 ...

This may not sound like much, but such improvement can be very valuable. In this first part of a two-part series, we will examine basic ideas behind the importance of condenser heat transfer, and in ...

Flue gas heat recovery systems represent a critical technological advancement in optimising energy efficiency and reducing atmospheric emissions in industrial and power generation settings. These ...

Heat pumps are having a moment in the spotlight—or as close to one as a heating and cooling appliance can get. Whether it’s ducted heat pumps, mini-splits, or even geothermal systems, there’s a buzz ...

Heating, ventilation and air conditioning (HVAC) is the technology for indoor and automotive ambient comfort. HVAC facilitates in managing the pleasant climate inside the cabin by controlling the ...

A heat pump heats and cools your home, functioning like a combined furnace and central air conditioner. Because they absorb and move heat from the air, heat pumps are exceptionally energy-efficient ...
