Abstract:
An air conditioning system comprising a coolant circuit that comprises an outdoor heat exchanger and an indoor heat exchanger, and positively pressurizing a room to be air conditioned, the air conditioning system comprising: a room temperature detection unit which detects the temperature in the room; an air blower which blows air that has been heat-exchanged with the indoor heat exchanger into the room; a blow-off temperature detection unit which detects the blow-off temperature from the air blower; and a control unit which determines whether or not the room has a negative pressure on the basis of the results detected by the room temperature detection unit and the blow-off temperature detection unit and which adjusts the amount of air blown by the air blower, the control unit controlling the air blower such that the air blower increases the amount of air blown if it is determined that the room has a negative pressure. Thus, by adjusting the amount of air blown in response to the change in the room temperature, it is possible to do without a pressure detection means, supply and exhaust ducts to be controlled according to the value of the pressure detection means and installation of air supply and exhaust fans, and to keep the room at a positive pressure at a low cost.
