<p>PURPOSE: A refrigerant system and a control method thereof are provided to remarkably improve heat transfer efficiency by increasing the amount of external heat exchange units used as an evaporator. CONSTITUTION: A refrigerant system comprises an outdoor unit(1), multiple inner units(2), high-pressure and low-pressure pipes(42,43), a refrigerant pipe, a pressure sensing unit, and multiple flow conversion units(13). The outdoor unit comprises an external heat exchanger(11) and a compressor. The indoor units comprise multiple internal heat exchangers. The high-pressure pipe guides refrigerants from the compressor to the internal heat exchangers. The low-pressure pipe guides the evaporated refrigerants from the internal heat exchangers to the compressor. The refrigerant pipe connects the external heat exchange units and the internal heat exchangers. The pressure sensing unit senses the pressure of the refrigerants. The flow conversion units convert the flowing direction of the refrigerants.</p> |
