[0011] Hereinafter, a reducer of a heat exchanger according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0012] FIGS. 1 to 9 illustrate a reducer (1) of a heat exchanger according to the present invention. Referring to FIGS. 1 to 9, the reducer (1) of the heat exchanger according to the present invention is connected at one end to the indoor air supply side of the heat exchanger (2) and at the other end to an air supply duct (3) for supplying air to the indoor side, so that components such as odor components, bacteria and viruses, fine dust, and harmful gases in the air supplied to the indoor side from the outside through the heat exchanger (2) are combined with ionized moisture and can be effectively captured and removed by an electrostatic precipitator (not shown) or filter device (not shown) installed on the air supply duct (3). It may be configured to include a main body (10), a chamber (20), a water replenishment unit (30), a sensor unit (40), a heater (50), a water supply unit (60), a carbon fiber bundle (70), a high voltage supply unit (80), and a control unit (90).

[0013] Here, the heat exchanger (2) may be configured to include an outside air intake port (1A) for introducing outside air into the interior, an indoor air supply port (1B) for supplying outside air introduced into the interior through the outside air intake port (1A), an indoor air intake port (2A) for introducing indoor air into the interior, an outdoor exhaust port (2B) for discharging air introduced into the interior through the indoor air intake port (2A) to the outside, and a heat exchange element (not shown) for heat exchange between the outside air and the indoor air, and the reducer (1) of the heat exchanger according to the present invention has one end connected to the indoor air supply port (1B).

[0014] The main body (10) is installed between the indoor air supply port and the air supply duct (3) and may be configured to include an inlet connection part (11) connected to the indoor air supply port of the heat exchanger (2), an outlet connection part (12) connected to the air supply duct (3) for supplying air that has passed through the heat exchanger (2) into the room, and an extension part (13) that connects the inlet connection part (11) and the outlet connection part (12), forms a flow path through which air can pass inside, and is expanded so that the flow path on the outlet connection part (12) side is wider than the flow path on the inlet connection part (11) side.

[0015] The main body (10) has an inlet connection part (11) formed in a circular shape corresponding to an indoor air supply port (1B), and an outlet connection part (12) formed in a square or circular shape so as to be connected to a flat rectangular air supply duct (3) as shown in FIGS. 1 to 3 or a circular air supply duct (3) as shown in FIGS. 6 to 9, and the outlet connection part (12) is formed to have a longer length or width than the inlet connection part (11).

[0016] The chamber (20) is installed on the upper part of the main body (10), specifically on the outlet connection part (12), and is formed to store water inside.

[0017] The water replenishment unit (30) replenishes water in the chamber (20) when the water level in the chamber (20) drops below a certain level. It may be configured to include a pump (31) installed inside the chamber (20) and a transfer pipe, one end of which is connected to the pump (31) and the other end of which is connected to a water tank (not shown) provided outside the main body (10) to transfer water stored in the water tank to the chamber (20). A pipe installation hole may be formed in the upper part of the chamber (20) to allow the transfer pipe to pass through.

[0018] The sensor unit (40) may be configured to include a water level sensor (41) installed inside the chamber (20), a turbidity sensor (42) that detects the turbidity of water contained inside the chamber (20), and a temperature sensor that measures the temperature inside the chamber. The water level information, turbidity information, and temperature information detected by the sensor unit (40) are transmitted to the control unit (90) in real time.

[0019] The heater (50) is installed in the chamber (20) to heat the water in the chamber (20), and heats the water to a temperature above a certain level so that ionization of the water can be easily achieved when high voltage is applied to the carbon fiber bundle (70) and the water through the high voltage supply unit (80) described later.

[0020] The water supply section (60) is formed to surround the outlet connection section (12). At least one side of the water supply section (60) is connected to the chamber (20), and a waterway (61) through which water supplied from the chamber (20) can flow is formed inside along the perimeter of the outlet connection section (12).

It is installed such that one end is exposed to the waterway (61) side through a connecting hole (12A) formed on the inner surface of the expansion part (13), and the other end is installed such that it is exposed to the flow path side so as to come into contact with the air flowing along the flow path inside the main body (10). The carbon fiber bundle (70) can be formed by bundling a certain amount of carbon fibers having a fine thickness so that the water supplied to the waterway (61) side can seep through the carbon fiber bundle (70) and move toward the other side of the carbon fiber bundle (70) exposed to the flow path side. Here, high voltage supplied from the high voltage supply unit (80) is applied to the carbon fiber bundle (70).

[0023] The high voltage supply unit (80) applies a high voltage to the water supplied through the waterway (61) of the water supply unit (60) or to the carbon fiber bundle (70) to induce a plasma discharge around the carbon fiber bundle (70), and ionizes the water molecules that have permeated the carbon fiber bundle (70) by the plasma discharge. The ionized water molecules bind to or adsorb to components such as odor components, bacteria and viruses, fine dust, and harmful gases in the air passing through the flow path of the main body (10).

[0024] The control unit (90) controls the operation of the pump (31) according to the water level value measured by the water level sensor (41). In addition, the control unit (90) controls the operation of the heater (50) according to the temperature value measured by the temperature sensor. In addition, the control unit (90) controls the operation of the high-voltage supply unit (80).

[0025] Meanwhile, the reducer (1) of the heat exchanger according to another embodiment of the present invention shown in FIGS. 6 to 9 is identical to the reducer (1) of the heat exchanger according to one embodiment of the present invention described with reference to FIGS. 1 to 5, except for the shape of the expansion part and the outlet connection part, and the rest of the configuration is the same, and a description thereof is omitted.

[0027] Therefore, the true scope of technical protection of the present invention should be determined solely by the technical concept of the appended claims. Explanation of the symbols
