Total heat exchange-type ventilating apparatus, and method for controlling same

Abstract

The present invention relates to a total heat exchange-type ventilating apparatus and to a method for controlling same, which involve sensing indoor and outdoor temperatures and humidities, calculating indoor and outdoor enthalpies from the sensed temperature and humidity information, and selectively operating in a heat exchange mode or in an outdoor air cooling mode in accordance with the result of comparing the sizes of the enthalpies, thereby controlling the indoor temperature and humidity to be maintained at comfortable levels. To accomplish this, the apparatus of the present invention comprises: a first exhaust chamber (30) and a second exhaust chamber (40); a first air supply chamber (10) and a second air supply chamber (20); a total heat exchanger (50) for exchanging heat between indoor air introduced from the first exhaust chamber (30) to the second exhaust chamber (40) and outdoor air introduced from the first air supply chamber (10) to the second air supply chamber (20); a bypass pipe (60) which forms an airflow channel for enabling outdoor air to be directly introduced into an indoor area without passing through the total heat exchanger (50) during a free cooling operation; a first temperature sensor (31) and a first humidity sensor (33) for sensing the temperature and humidity of the indoor air; a second temperature sensor (11) and a second humidity sensor (13) for sensing the temperature and humidity of the outdoor air; and a control unit (70) which calculates the enthalpies of the indoor air and outdoor air on the basis of the temperatures and humidities of the indoor air and outdoor air, compares the sizes of the enthalpies, and controls an outdoor air inflow path.

Description

technical field [0001] The present invention relates to a total heat exchange type ventilation device and a method of controlling the same, and more particularly, to a total heat exchange type ventilation device which detects the temperature and humidity of indoor and outdoor areas, and according to the detected The temperature and humidity information calculates the enthalpy of the indoor and outdoor areas, and then selectively operates in the heat exchange mode or the outdoor air cooling mode through the comparison result of the enthalpy, thereby controlling the indoor temperature and humidity to maintain a comfortable level. Background technique [0002] Cooling or heating equipment is installed in rooms or offices to cool or heat indoor areas when seasons change, and the cooling or heating equipment includes air conditioners, boilers, etc. to cool or heat indoor air. [0003] A room or office in which such cooling or heating equipment is installed is kept airtight to inc...

Problems solved by technology

When in the rainy season, the outdoor area is cool but humid, and the outdoor moisture may be directly introduced into the indoor area, which makes the indoor area very humid
