Description

Air Conditioner {Air Conditioner}

The present invention relates to an air conditioner capable of simultaneously or separately performing ventilation, dehumidification, and air purification.

An air conditioning system is a system that performs a dehumidifying cooling or humidifying heating operation that adjusts the temperature and humidity of a divided space, or a ventilation operation that exchanges indoor and outdoor air.

Air conditioning systems are used in various places, from wide spaces in large buildings and public spaces to narrow spaces where individuals live and work. Efforts are being made to develop technologies to overcome these drawbacks.

For example, in a house or commercial building, an energy recovery type ventilation device that recovers energy from indoor and outdoor air is installed for ventilation. In general, an energy recovery type ventilation system uses a total heat exchanger capable of recovering heat from air or transferring heat to air.

In addition, technology that adds a cooling and heating function by inserting a heat pump into a ventilation device, such as US registered patent US 6,918,263 or US 8,943,848, beyond a general ventilation operation function, also appears. In the case of US registered patent US 6,918,263, a dehumidifying operation function is added by inserting a dehumidifying rotor into a ventilation device, but the configuration of the entire system becomes complicated and manufacturing cost increases due to the addition of parts.

The total heat exchanger is a part used for the purpose of recovering heat from the air, and the dehumidifying rotor is used for the purpose of recovering moisture from the air. Since both the total heat exchanger and the dehumidification rotor use one method (air-air heat exchanger) to exchange heat and moisture between air and air, a liquid-liquid heat exchanger that exchanges heat between liquid and liquid or between liquid and air The volume is very large compared to the liquid-air heat exchanger that exchanges heat. Therefore, it is not easy to adopt two different parts of the total heat exchanger and the dehumidifying rotor into one air conditioning system.

Korean Patent Registration No. 1061944 omits the installation of a total heat exchanger and introduces a ventilation system technology using a dehumidifying rotor and a heat pump, but according to this technology, the function of recovering ventilation energy during ventilation operation cannot be executed.

In addition, demand for maintaining pleasant indoor air in industrial sites, public institutions, and homes continues to increase, and dehumidifiers are installed in the summer and humidifiers, which are separate devices from the dehumidifier, are installed in the winter. However, from the consumer's point of view, there is a burden of purchasing, installing, and managing separate devices for dehumidifying and humidifying functions, and inconveniences such as having to install a water tank in the humidifier.

In addition, in the case of using one dehumidifying rotor, when the dehumidifying rotor is out of order, there is a problem in that dehumidification and energy recovery cannot be performed during ventilation.
