The carbon dioxide concentration sensor 168 detects the concentration of carbon dioxide contained in the indoor air and provides it to the controller 170.

Here, the controller 170 may control the opening and closing of the exhaust damper 167 according to the detection signal of the carbon dioxide concentration sensor 168, and the exhaust line and the second inlet 111b while controlling the inlet damper 115 described above. Can be controlled proportionally.

That is, all the control of the inflow of outdoor air or the intake of indoor air into the casing 110 and the exhaust of exhausting the indoor air to the outside are performed by the controller 170 of the inflow damper 115 and the exhaust damper 167.

The heater 150 is installed in the communication space 113 of the casing 110 as shown in FIG. 2 while operating by the controller 170 to heat air to a set temperature.

Here, when the thermo-hygrostat device 100 of the present invention is installed at, for example, a computer room, the heater 150 may be omitted because heating is not necessary due to the characteristics of the equipment.

The heater 150 may include, for example, a heat generator 151 and a heat conductor 152 as shown in FIG. 4.

The heating element 151 is a member that generates heat through power supply by the controller 170, and a configuration used for a conventional electric heater such as a heating wire may be applied. Alternatively, the thermoelectric element may be applied.

On the other hand, the coil 131 constituting the above-described evaporator 130 may be formed of an oval coil having a long axis in the moving direction of air while being formed in an elliptical cross section as shown in FIG.

The oval coil 131 may have an extended thermal contact area with air to improve the cooling efficiency of the air, and prevent the air flow at the rear end of the coil from vortexing to prevent scattering of condensate.

For example, the coil of the circular cross section becomes narrow in thermal contact area with the moving air, and in particular, since the outer peripheral surface of the rear end where the air escapes toward the outlet 112 has little contact with air, moisture forms in the form of droplets, Condensed water droplets flow through the outer circumferential surface of the thermal contact coil 131 and are scattered to the outlet 112 by the vortex phenomenon of air.

On the other hand, since the oval coil 131 has a thermal contact area with the moving air to the outlet 112 side, the moisture generated on the outer circumferential surface is minimized in the form of droplets, and the droplets are not scattered along the airflow even if the droplets form. Flows downward.

Accordingly, the oval coil 131 of the present invention smoothly cools the air by the blowing fan 120 and prevents the water from scattering to the outlet 112.

As such, when the evaporator 130 is composed of an oval coil 131 having an elliptical cross section having a long axis in the direction of air movement, a blower fan having a higher wind speed than the existing blower fan 120 is prevented from scattering of condensate. 120 can be employed to realize high efficiency and high capacity devices.

Here, the casing 110 is provided with a not shown drain for discharging the condensed water.

Meanwhile, the above-described heat dissipation fins 132 may be stacked while being spaced apart through a spacer as shown in FIG. 6.

For example, the spacer may be configured as the protruding tube 133 as shown in FIG. 6.

As shown in FIG. 6, the protruding pipe 133 protrudes in a tubular shape through a penetrating portion of the oval coil 131 in the same manner as the heat dissipation fin 132 and is caught by another heat dissipation fin 132.

That is, the heat dissipation fins 132 are fitted in the stacking state of the oval coil 131 through the protruding tube 133 and spaced apart by the length of the protruding tube 133 as the other heat dissipation fins 132 are caught by the protruding tube 133. It is stacked in a closed state and cools the air while flowing air through the space.

In addition, the evaporator 130 of the present invention may further include a moisture scattering prevention guide 180 as shown in FIG.

The moisture scattering prevention guide 180 is configured to prevent the water from scattering to the outlet 112 while interfering in the form of blocking the water on the surface of the evaporator 130 moving with the air by the excess wind speed of the blowing fan 120. Element.

For example, the moisture scattering prevention guide 180 may include a pair of shield plates 181 installed on the heat dissipation fins 131 in a state adjacent to the oval coil 131 and the protruding pipe 133 as shown in FIG. 8. Can be.

The pair of shield plates 181 are installed in a hat shape while being symmetric about the long axis of the oval coil 130 having an elliptical cross section, as shown in an enlarged view of the rear side of the respective oval coils 130. To form a slope.

That is, the shield plate 181 forms an inclined surface at the outlet 112 side of the oval coil 131, thereby interfering with the air contacting the outer circumferential surface of the oval coil 130, and water is scattered to the outlet 112 by the excessive wind speed. To prevent it.

As shown in FIG. 8, the shield plate 181 includes an inlet 181a having a narrow mutual gap between the inclined surfaces and a discharge part 181b having a large mutual interval between the inclined surfaces, thereby preventing water from scattering. While preventing the air flow rate is variable, the air is smoothly discharged.

That is, the air passing through the oval coil 130 flows into the inlet 181a together with the water and the flow rate increases as the interval between the inclined surfaces becomes narrower, and the discharge portion 181b is in a state where water scattering is interfered by the inclined surfaces. As the gap is widened while passing through, the cross-sectional area is smoothly discharged to the outlet 112.

On the other hand, the communication space 113 of the casing 110 is provided with a sterilization unit 600 may decompose and sterilize harmful substances contained in the air moving to the outlet.

Ultraviolet rays have germicidal power as it is known. Particularly, those having a wavelength of around 250 nm have a large sterilizing power, and 99% of Escherichia coli, Diphtheria, and Heterogeneous bacteria are sterilized by irradiating ultraviolet ray having a intensity of 100 μW per 1 cm 2 for 1 minute.

The type or detailed configuration of the ultraviolet lamp 620 is well known in the art to which the present invention pertains, and thus detailed description thereof will be omitted.

The photocatalyst grill 630 is a member that decomposes harmful substances while reacting with the light of the ultraviolet lamp 620 by accommodating the ultraviolet lamp 620 while the photocatalyst is coated.

Here, the type of photocatalyst is not limited, and any configuration known in the art to which the present invention belongs, such as titanium dioxide photocatalyst, may be adopted.

Titanium dioxide photocatalysts are n-type semiconductors that, when subjected to ultraviolet light (400 nm), form electrons and electron holes to form hydroxy radicals (-OH) and super oxides with strong oxidizing power. Hydroxy radicals and superoxide decompose organic compounds into water and carbon dioxide.

In this way, pollutants in the air are oxidized and decomposed into harmless water and carbon dioxide, and the organic compounds, which are contaminants in the water, are decomposed into water and carbon dioxide. Since bacteria are also organic compounds, they are oxidized and decomposed by the strong oxidizing action of the photocatalyst and sterilized.

The photocatalyst grill 630 is formed in a tubular shape as shown in FIGS. 9 and 10 so that the photocatalyst is coated on the inner circumferential surface and the outer circumferential surface, and coupled to the base member 610 in a detachable state. It is accommodated therein and transmits the light of the ultraviolet lamp 620 to the outside as the plurality of transmission holes 631 are formed.

As shown in the drawing, the protruding plate 641 protrudes in an arc shape on the inner circumferential surface of the photocatalyst grill 630 and bypasses air as it protrudes alternately along the longitudinal direction of the photocatalyst grill 630 while forming a symmetrical state.

That is, since the air introduced into the photocatalyst grill 630 moves in a zigzag form by the alternating protrusion plate 641, the contact time with the photocatalyst is increased, so that the harmful substances can be smoothly purified.

On the contrary, the photocatalyst guide 640 may be configured as a screw guide plate which protrudes in the form of a screw along the inner circumferential surface of the photocatalyst grill 630 to guide the air in a rotating state.

Meanwhile, the sterilization unit 600 of the present invention may further include a reflecting plate 650 as shown in FIG. 10.

Reflector 650 is a component for inducing the reaction of the photocatalyst coated on the outer circumferential surface of the photocatalyst grill 630 by reflecting the light of the ultraviolet lamp 620 transmitted through the transmission hole 631 of the photocatalyst grill 630 to be.

Here, as the ultraviolet lamp 620 is accommodated in the photocatalyst grill 630, light is directly irradiated only to the inner circumferential surface of the photocatalyst grill 630, and light is not directly irradiated to the outer circumferential surface.

As shown in FIG. 4, the reflecting plate 650 directly reflects the light of the ultraviolet lamp 620 at one side of the photocatalyst grill 630 and directly irradiates the outer circumferential surface of the photocatalyst grill 630, thereby The photocatalyst coated on the outer circumferential surface may decompose harmful substances in the air while reacting smoothly with the light of the ultraviolet lamp 620 reflected by the reflector 650.

The reflective plate 650 may be formed of, for example, a metal mirror having durability. One side of the photocatalyst grill 630 is fixed to the base member 610 or attached to the casing 110 as shown in FIG. 10. Or on both sides.

According to the power-saving constant temperature and humidity device 100 using the outside air as described above, the summer in summer because the inflow damper 115 inflows indoor air or outdoor air based on the enthalpy (heat content) of outdoor air or indoor air. Energy consumption can be reduced by cooling by using outdoor air in seasons except for, especially when only cooling the air for dehumidification, recycle the condensation heat generated during cooling to compensate for the temperature of the air in the reheat coil (144) Energy consumption can be further reduced.

In addition, the controller 170 controls the inflow damper 115 to open and close the exhaust damper 167 according to the carbon dioxide concentration of the indoor air, thereby introducing the outdoor air and ventilating the indoor air.

In addition, since the heat of the heating element 151 constituting the heater 150 is conducted through the heat conductor 152 to be in thermal contact with the air, energy consumption due to the heating of the air may be minimized.

As the remote controller 190 is provided, remote control of the controller 170 through the communication device is possible, so that the temperature / humidity of the room can be conveniently adjusted.

In addition, as the evaporator 130 is composed of an oval coil 131 having an elliptical cross section having a long axis in the direction of movement of air, the heat exchange area may be expanded to minimize condensation of condensate, and in particular, the air flow of the oval coil 131. Due to the minimization of the vortex on the back of the coil, it is possible to prevent the scattering of condensate, and thus, a blower fan 120 having a higher wind speed than that of the existing blower fan can be employed, thereby achieving a high efficiency and high capacity device.

In addition, since the wind speed or capacity of the blowing fan 120 can be increased, the temperature and humidity of the entire room can be maintained uniformly.

In addition, since the protrusion tube 133 constituting the spacer is formed on the heat dissipation fin 132 is caught by another heat dissipation fin 132, the heat dissipation fins 132 may be firmly fixed while forming a spaced state.

In addition, the pair of shield plates 181 constituting the moisture scattering guide 180 is formed in the shape of the hatshade forming an inclined surface while interfering the water through the inlet 181a is narrow gap, the discharge is widened Since the air is discharged through the unit 181b, the air may be discharged in a state in which scattering of moisture is blocked even by the excessive wind speed.

As the remote controller 190 is provided, remote control of the controller 170 through the communication device is possible, so that the temperature / humidity of the room can be conveniently adjusted.
