Description

Heat exchanger with structure of Expanded Poly Propylene

The present invention allows the partition panel and the partition wall to be assembled into a block type according to the supply / exhaust zone of the foamed polypropylene resin (EPP) material, which is manufactured, assembled, and handled compared to conventional metal sheet forming work. Performance and productivity are remarkably improved, especially in the case of post-management due to change of supply and exhaust line or change of diameter of pipe connection, it is easy to partially attach and detach the partition panel to the supply and exhaust zone, which greatly improves maintenance and variable installation. A block assembled foamed polypropylene resin type heat exchanger characterized by the above-mentioned.

In general, a ventilation system using an electric heat exchanger is used to discharge polluted indoor air of a building such as an apartment house, an office or a department store, a large mart to the outside, and to supply external air to the indoor space.

That is, in order to ventilate the indoor air, the normal electrothermal 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 total heat exchanger is typically formed of a box-shaped enclosure using a metal (iron plate, tin plate, etc.) material, so that the air flow transfer through-hole of the enclosure is combined with other duct pipes to form a supply and exhaust line. The connector is formed.

However, these connectors are also made of metal (iron plate) material (connector tube or back draft damper), and the enclosure is corroded (rusted) by vaporization and liquefaction generated during heat exchange, which causes the indoor environment to be polluted. .

In addition, the conventional metal type heat exchanger is a form that is assembled by bending a thin iron plate, the lifting or spacing caused by the fine assembly tolerance is generated, causing noise and vibration due to the air flow transfer, due to the characteristics of the metal plate to form a separate heat insulating material There is a problem that the heat exchange efficiency is not high, such as is required.
