Dual Capacity

 ◦   Dual capacity Heat Pump Equipment is offered by many manufactures as an upgrade to the single capacity heat pump. The primary advantage of the dual capacity heat pump is the ability to operate at a lower capacity most of the time when a building zone is under moderate load conditions with the capability to increase the heat pump capacity when the higher building load is required.

 ◦   The dual capacity heat pump compressor is a constant speed scroll compressors and is very similar to the single capacity heat pump compressor except the dual capacity equipment has the capability to recirculate some of the refrigerant during low capacity operation.

 ◦   The dual capacity heat pump will operate in the low capacity most of the time allowing more moisture removal from the build zone. During low capacity the compressor uses less power, and normally switches from to high capacity at about 67% of capacity.

 ◦   The Dual capacity heat pump is popular with residential customers and is less complex than variable capacity heat pumps and more economical to own.
