Abstract

An additive heat transfer unit (AHTU) can be part of or added to an air source heat pump HVAC system. The heat pump system can include a compressor, an expansion valve, first and second air source heat exchangers, and a reversing valve. The system can have a cooling mode and a heating mode, such that in the cooling mode the first air source heat exchanger functions as an evaporator and the second air source heat exchanger functions as a condenser, this being reversed in the heating mode. The AHTU can include a liquid source heat exchanger that can be used to increase the efficiency of the system.
