Title:
HYBRID HEAT PUMP STYLE AIR CONDITION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/050663
Kind Code:
A1
Abstract:
This present invention relates to a hybrid heat pump heating/cooling system. The system improves heating efficiency by solving the conventional problems caused by the decline of external temperature during winter. In addition, the system can be controlled easily and maximize the stability of heating and cooling operations, as the switching operation between heating and cooling modes is enabled by only controlling a heating medium pipe. The hybrid heat pump heating/cooling system according to the invention comprises: a compressor; a high heat temperature exchanger connected to the compressor; a condenser connected to the high heat temperature exchanger; an expansion valve connected to the condenser; a refrigerant pipe having both sides connected with the expansion valve and the compressor respectively; an evaporator for evaporating an expanded refrigerant in the expansion valve through heat exchange with a heat medium and feeding the evaporated refrigerant to the compressor; an outdoor unit having an outdoor heat exchanger with the heat medium flowing therein; an air conditioning device having a fan and an indoor heat exchanger with a heat medium flowing therein; and a heat medium pipe for controlling the circulation direction of the heat medium in the heating and cooling modes.
