Multipurpose Heat Exchanger for Airconditioning and Dehumidification and Method for Controlling Thereof

The present invention relates to a multipurpose total heat exchanger capable of performing cooling and dehumidifying functions and a control method thereof, and more particularly, to ventilation and air conditioning of indoor air, and when dehumidifying indoor air by a plurality of heat exchange modules, the existing temperature It relates to a multi-purpose total heat exchanger capable of performing cooling and dehumidifying functions that can maintain and a control method thereof.

The total heat exchanger is a ventilation device to ventilate indoor air. When supplying outdoor air to the room or discharging indoor air to the outside, the exhausted indoor air and the intake indoor air exchange heat to reduce heat loss generated during the ventilation process. It corresponds to a device that can reduce.

Patent Document 1 discloses an example of a ventilation system according to the prior art. The total heat exchange element is disposed in the inner space of the total heat exchanger main body, and intake and exhaust ports are formed on the indoor and outdoor side surfaces, respectively. However, the existing total heat exchanger as in the prior art has a problem in that additional installation costs may be incurred because an air conditioner for controlling indoor humidity is separately required.

Patent Document 2 discloses an example of a total heat exchanger including a dehumidification module. This is characterized in that the dehumidification module is provided inside the existing total heat exchanger, so that the indoor humidity can be controlled while ventilating the indoor air without a separate air conditioner. However, such a total heat exchanger has a problem in that a separate air conditioner for heating and cooling is required.

On the other hand, the conventional total heat exchanger does not have an air cleaning module for filtering fine dust generated indoors and outdoors when it is sucked in, so there is a problem in that a separate air cleaning device must be provided indoors. In addition, a total heat exchanger equipped with a sterilization function is required to prevent the spread of infectious diseases, but there is no total heat exchanger that implements all functions of heating, cooling, dehumidifying, cleaning, and sterilization, so research on this is urgent.
