INTEGRATED AQUA-AMMONIA CHILLER/HEATER

摘要

An aqua-ammonia chiller apparatus is modified to include a heater function by providing a refrigerant by-pass (52) for directing refrigerant to a heat exchanger (19) capable of selectively functioning as a condenser during a heating mode or an evaporation during a cooling mode without passing through the apparatus condenser (14) during the heating mode.
