(57) The present invention relates to air conditioning systems, and more particularly,
to an air conditioning system which can control a refrigerant flow rate to a heat
exchanger exchanging heat with room air to be optimum; and a method for controlling
the same.
The air conditioning system includes an outdoor heat exchange part including a compressor
for compressing refrigerant, an outdoor heat exchanger for making the refrigerant
to heat exchange with outdoor air, and an expansion device for expanding the refrigerant,
an indoor heat exchange part including a pump for making refrigerant in a flow path
independent from the outdoor heat exchange part to flow, at least one indoor heat
exchanger for making the refrigerant heat exchange with room air, and a flow rate
control device for controlling a flow rate of the refrigerant, and a hybrid heat exchange
part for making the outdoor heat exchange part and the indoor heat exchange part,
which are independent from each other, to heat exchange with each other.
According to this, the air conditioning system can be installed on a multistory building
without limitation of a height of the building as far as a capacity of the pump permits.
Moreover, even if a refrigerant pipe is long, the air conditioning system is applicable
even to a system with a refrigerant pipe line longer than the related art as far as
the capacity of the pump permits, and fine control of a room air temperature is possible.
