AC Tip: Heat Pump Air Duct Requirements

Monday, July 23rd, 2012 at 8:00 am

Heat Pump Technology

Growing in popularity today in Rockledge are heat pumps, devices that transfers thermal energy from one location to another, usually in the direction of from a colder temperature to higher and generally the opposite of the natural flow.  While compressor-driven air conditioners and freezers are technically heat pumps, “heat pump” is the term that usually implies one of the less-common devices in the class that are not dedicated to refrigeration-only.

A heat pump that maintains a thermally conditioned-space can be used to provide either heating or cooling, depending upon whether the environment is cooler or warmer than the conditioned-space.  Typically pumps utilize some thermal energy from the environment itself, such as the natural heat beneath the Earth’s surface.

By simply transferring the energy rather than producing it, heat pumps are being more seriously considered as attractive alternatives to provide an efficient and clean system for conditioning public and living spaces.

Change of Use

In considering a change from an existing system to a heat pump, there are many details to compare to see if it makes any sense at all.

Since a heat pump typically moves conditioned air through ductwork, the advantages of the change are much more realistic with a system of pre-existing ducts such as a forced air furnace or central air-conditioning unit.  While a heat pump often requires a larger volume of ducts, the old network of metal tunnels was often over-sized for inefficient furnaces and should do fine in a conversion to a heat pump.

The Right Data

Since the required formulas are dependent upon variables such as size, distance, volume and oomph, the design is strategic and makes all the difference.  Consulting with a trained and experienced Rockledge AC professional such as Next Generation Air & Heat is critical to the success of the conversion.
