Air Source Heat Pumps

There are basically two types of air source heat pumps. The design and layout of the building will determine which type is best suited for your

needs.

Packaged Heat Pumps

Packaged heat pumps consist of an entire package consisting of a compressor and both heat exchangers located on the exterior of the property. Ductwork channels conditioned air from the exterior heat pump to the building interior. Interior air ductwork provides all interior heating and cooling.

Split System Heat Pumps

The split system heat pump is by far the most common heat pump in use today. The exterior unit consists of the compressor and an exchanger. The indoor unit consists of an exchanger and a duct air handling unit. Ductwork provides for entire building with heating and cooling. The flexibility of this configuration allows for a more versatile varied installation.

There are more variations of the split system heat pumps such as:

The triple function heat pump. This variation is the same as the split system with the addition of using excess heat from cooling for almost free heating of domestic water during summer months.

The free delivery split heat pump system. This variation uses no ductwork. The exterior unit consists of the compressor and an exchanger. The indoor unit consists of multiple exchangers located at various locations or zones and independently controled for temprature.

Heating Seasonal Performance Factor (HSPF) is the unit used for air source heat pump efficiency. Ranges are typically 7.6-8.2

Seasonal Energy Efficiency Ratio (SEER) is the unit used for air source heat pump cooling efficiency. Ranges are typically 13-16 with higher the better.
