Description

Air Conditioner

The present invention relates to an air conditioning device that can perform ventilation, dehumidification, and air cleaning simultaneously or separately.

An air conditioning system is a system that performs dehumidifying cooling or humidifying heating operation to control the temperature and humidity of a partitioned space, or ventilation operation to exchange air between indoors and outdoors.

Air conditioning systems are used in a variety of places, from large buildings and large spaces in public places to small spaces where individuals live and work. However, due to the lack of electricity supply in the summer, air conditioning systems that use electricity as the main power source are used to replace air conditioning systems, Efforts to develop technology to overcome these shortcomings are ongoing.

For example, in homes or commercial buildings, energy recovery ventilation devices that recover energy from air passing indoors and outdoors are installed for ventilation purposes. Generally, energy recovery ventilators use a total heat exchanger that can recover heat from the air or transfer heat to the air.

In addition, beyond the general ventilation operation function, there are also technologies that add cooling and heating functions by inserting a heat pump into the ventilation device, such as US registered patents US 6,918,263 and US 8,943,848. In the case of US registered patent US 6,918,263, a dehumidifying operation function was added by inserting a dehumidifying rotor inside the ventilation device, but the addition of parts complicates the overall system configuration and increases manufacturing costs.

A total heat exchanger is a part used to recover heat from the air, and a dehumidifying rotor is used to recover moisture from the air. Both the total heat exchanger and the dehumidifying rotor use a method (air-air heat exchanger) to exchange heat and moisture between air and liquid, so it is 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 performs heat exchange. Therefore, it is not easy to adopt two different components, a total heat exchanger and a dehumidification rotor, into one air conditioning system.

Korean Patent No. 1061944 omits the installation of a total heat exchanger and introduces a ventilation device 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 implemented.

In addition, the demand to maintain comfortable indoor air in industrial sites, public institutions, and homes continues to increase, and dehumidifiers are installed in the summer and humidifiers, a separate device from the dehumidifier, are installed in the winter. However, from the consumer's perspective, there is the burden of having to purchase, install, and manage separate devices for the dehumidifying and humidifying functions, and there are inconveniences such as having to install a water tank in the humidifier.

Additionally, when using a single dehumidification rotor, there is a problem in that dehumidification and energy recovery cannot be performed during ventilation if the dehumidification rotor is broken.
