Insulation and minimizing leakage frame rate of the air conditioner

The present invention relates to a modular frame of an air conditioner having a high heat insulation effect, wherein the modular frame is divided into an outer member located on the outer surface of the modular member and an inner member located on the inner surface of the modular member, Preventing block to prevent heat interference between the outer member and the inner member, and a frame for minimizing the leakage rate of the air conditioner.

The air conditioner is a device for controlling the cooling and heating of the room, and functions not only for the air-conditioning and heating, but also for humidifying and dehumidifying, as well as for ventilating the room air or purifying the air by sucking in the outside air. The air conditioner is composed of an air blower, a cooling / heating coil, a humidifier, an air filter, a damper for controlling the air volume, and the air conditioner is sealed by an insulating frame and an insulating panel constituting the external shape of the air conditioner.

However, since a large temperature difference is generated between the inside and outside of the heat insulating frame during the operation of the air conditioner, in the case of the summer, the internal cold air is transferred to the outside through the frame, In the case of winter, the outside cool air is transferred to the inside of the frame, causing condensation inside the air conditioner. These condensation phenomena may cause corrosion of the outer surface of the air conditioner, damage to the building due to leaking of the building, or formation of high temperature and high humidity condition inside the air conditioner, so that conditions for microorganisms such as bacteria may be established, It will adversely affect the environment of high-clean buildings.

Therefore, the heat insulating frame of the air conditioner has a heat insulating function so that the heat inside and outside the frame is not exchanged. In general, in the industry, the heat conductive characteristic of the heat insulating frame structure is divided into classes, And the thermal conductivity characteristics of the frame are classified.

The main classes are the T class (heat transfer rate grade) and the TB class (heat grade). The T class is related to the heat transfer rate and measures the degree to which the internal cool air passes through the panel at right angles. It measures the degree of heat transfer and means the degree to which the cold bridging phenomenon can be blocked.
