ABSTRACT:
A boosted air source heat pump system is presented having a primary compressor, a booster compressor and an economizer. On activation of the heat pump system, the primary compressor is operated. When the primary compressor cannot meet the demand, the booster compressor is activated, but only upon receipt of a signal enabling the operation of the booster compressor. The booster compressor is preferably a variable speed booster, and its speed is controlled to be at or between an absolute minimum speed and an absolute maximum speed. The booster may be on the low side or the high side of the primary compressor. The operation of the economizer may be modulated to meet the demand on the system.
