PURPOSE: An air flowmeter of a heat exchange type and an air conditioning system comprising the same are provided to accurately measure the volume and the temperature of the outdoor air and to absorb the waste heat discharged through the indoor air. CONSTITUTION: An air flowmeter of a heat exchange type comprises heat exchange pipes(10,20) for absorbing or discharging the heat, and a pressure gauge. The heat exchange pipes are installed in an outdoor-air intake pipe. The pressure gauge measures the pressure difference between the front and the rear of the heat exchange pipe. The waste heat obtained from an outdoor-air discharge pipe is heated in the heat exchange pipe. The area of the heat exchange pipe is 30-50% of the area of the outdoor-air intake pipe. An anti-wind plate is formed on the front of the heat exchange pipe and the pressure gauge is formed on the front of the anti-wind plate. |
