Heat exchanger with structure of Expanded Poly Propylene}

The present invention is the main body of the total heat exchanger divided into two upper and lower cases, and / or various connections (coupled duct connection flange pipe, back draft damper for preventing the backwind) and the shielding plate (closing closing plate) coupled to the main body according to the selection. ) By injection molding of ABS or EPP (Expanded Poly Propylene) resin, which significantly reduces noise and vibration as compared to conventional electrothermal exchangers using metal materials, as well as vaporization and liquefaction during heat exchange. The foamed polypropylene (EPP) resin type heat exchanger can be easily installed according to the flow path, characterized in that the main body is formed so as not to corrode (prevent rust), and the heat exchange efficiency is greatly improved by excellent heat insulating properties. It is about.

In general, the total heat exchanger is a device that transmits the enthalpy of the exhaust side air to the intake side air by passing the supply air and the exhaust air through the heat exchanger in order to improve indoor air quality and energy efficiency while maintaining indoor air conditioning.

That is, in order to ventilate the indoor air, the conventional total heat exchanger is a device that first exchanges outdoor air with indoor air discharged to the outside so that sudden cold air and heat do not flow from the outside to the inside.

Therefore, the total enthalpy heat exchanger discharges the volatile organic compound material generated in the room through the exhaust and keeps the air in the room pleasantly by sucking the filtered fresh air into the room.

When the air in the air-conditioned room is discharged to the outside, the exhaust fan installed in the total enthalpy heat exchanger operates. At this time, air passing through the total enthalpy heat exchanger element in the room is contaminated air And is discharged to the outside.

On the contrary, when the air supply fan installed in the total enthalpy heat exchanger is operated, air is sucked into the room while passing through the total enthalpy heat exchanger element from outside with a static pressure generated.

At this time, heat and mass transfer are achieved through the total heat exchanger element and the energy loss through the ventilation is minimized.

In addition, when the air supply fan and the exhaust fan of the total heat exchanger are operated at the same time, the positive pressure of the indoor and the outdoor positive pressure are formed to be kept constant.

However, such a conventional heat exchanger is typically formed of a box-shaped enclosure using a metal (iron plate, tin plate, etc.) material, and combined with other duct pipe to form a supply and exhaust line in the through-hole for conveying the airflow of the enclosure. The connector is formed as much as possible, but this is also made of metal (iron plate) material (connector tube or back draft damper), so that the enclosure is corroded (rusted) due to vaporization and liquefaction generated during heat exchange. Will cause.

In addition, the conventional metal type total enthalpy heat exchanger is a form assembled by bending a thin steel plate. The metal type total enthalpy heat exchanger is a form assembled by bending a thin steel plate. The metal type total enthalpy heat exchanger generates noise and vibration due to airflow, And the heat exchange efficiency is not so high.

In addition, the above-described conventional heat exchanger is generally manufactured so that the flow line of the supply and exhaust air flows only in one direction (one direction), and the flow direction of the flow path is selectively and flexibly installed in accordance with various flow direction designs at the construction site. Problems such as poor workability and usability continue to continue.

The present invention is to solve the above-described problems, the technical gist of the main body of the heat exchanger divided into two upper and lower cases, and / or various couplings coupled to the body according to the selection of choice (duct connection flange pipe, backwind Prevents back draft dampers and blocking plates from injection molding with ABS or EPP (Expanded Poly Propylene) resin, resulting in less noise and vibration than conventional electrothermal exchangers made of metal. It is not only significantly reduced but also formed by the vaporization and liquefaction generated during heat exchange so that the main body is not corroded (prevents rust), and excellent heat insulation allows for a fluid installation according to the flow path line so that the heat exchange efficiency is greatly improved. It is an object to provide an easy expanded polypropylene (EPP) resin type heat exchanger.

In addition, the present invention is formed so that the four-way cross-flow path formed in the main body can be selectively and fluidly installed according to the direction, as well as the cover is formed on the upper and lower cases, respectively, to ensure the fluidity in the direction of the supply and exhaust flow path In addition, the upper and lower positions can be installed to change the installation is easy to customize the site, as well as to provide a convenient workability and its purpose.

In addition, the present invention forms a mounting block on one side and the other side of the air supply and exhaust fan installed in the main body to prevent shock and vibration generated when driving the air supply and exhaust fan, as well as injection-molded with EPP material It is an object of the present invention to provide a wire storage groove for improving the arrangement of various wires and wires by the characteristics of the main body, thereby improving work convenience according to installation and maintenance.
