Heat exchange with the hot water circulating the coil-type ventilation heating pipe 280 located in the upper duct 250.

The heat exchange process of the circulating hot water and the outside air is as follows.

The cold outside air sucked through the suction port exchanges heat with hot water circulated through the boiler 110 to the coil-type ventilation heating pipe 280, thereby increasing the temperature of the outside air. As the air constantly raised by heat exchange is supplied to the room, the room temperature can be properly maintained.

That is, the control unit 400 installed in the open space 700 is operated and the operating state of the supply blower 230 by the temperature detector 401, the pollution detector 402, the timer 403 and the constant pressure detector 241. The control unit also controls the ventilation of the open space 700 and the ventilation function state through the temperature detector 401, the pollution detector 402, and the timer 403.

Referring to FIG. 9, the control unit 400 installed in the open space 700 may operate in an automatic mode in which the supply blower 230 is operated according to the degree of contamination detected by the pollution detector 402. It is preferred that the supply blower 230 is configured to be set to a time mode in which the operation is performed and a manual mode in which the user directly determines the operating state.

Generally, the main cause of indoor air pollution is carbon dioxide (CO₂), which is a colorless and odorless gas. The specific gravity is 1.529 for air 1, which is heavier than air. Carbon dioxide (CO₂) is often generated during microbial degradation, human metabolism, tobacco smoke, combustion appliances and heat cookers, and carbon dioxide (CO₂) exceeds 3000ppm while the combustion appliance is in operation. The environmental standard of indoor air of CO₂, which is determined by Korean Building Law and Environmental Conservation Act, is 1000ppm per hour.

In the operation of the automatic mode, the supply blower 230 is operated when the pollution detector 402 for detecting the indoor concentration of carbon dioxide (CO₂), which is the main cause of indoor air pollution, is larger than the preset appropriate amount of carbon dioxide. It is known that the supply blower 230 is stopped when the amount of carbon dioxide is less than a predetermined amount, and the general setting criterion is that the supply blower 230 is driven at a carbon dioxide concentration of 1500 ppm and the supply blower 230 is stopped at a concentration of 1000 ppm or less. However, it can be set by the user.

The time mode is preferably operated by a timer 403 that allows the user to set the operating time zone of the supply blower 230 for each day or week.

In the manual mode, the user may drive the supply blower 230 due to the necessity of smell and generation ventilation as food cooking in an open space.

In addition, the supply blower 230 is preferably the rotational speed is shifted by the constant pressure detector 241 installed in the first supply duct 240. The static pressure detector 241 may be provided to provide an optimal amount of ventilation for each space due to an increase or decrease of the ventilation amount due to a blockage or an increase in the amount of ventilation due to indoor air pollution degree.

It is preferable to provide at 262. This is because the air pollution degree of the open space 700, that is, the amount of indoor carbon dioxide is greater than the preset appropriate amount of carbon dioxide, the proportional expression wave motor 262a is relatively opened, and if the amount is less than the predetermined amount of suitable carbon dioxide, the proportional expression wave motor 262a is opened relatively less. It is to control the air ventilation amount.

The timer 423 sets the opening and closing function of the dam motor 262a installed in the second branch duct 262 of the open space 700 for each time zone and flows into the open space 700 through the second diffuser 272. Unnecessary ventilation can be reduced by blocking the elevated air to a constant temperature. For example, since there is no person in the open space 700 at nighttime, there is no need for ventilation, so the user sets the timer from 10 pm to 5 am to block the incoming air ventilation. To close. In this case, the driving and stopping of the supply blower 230 may also be a time mode function of the timer 403 in the open space.

Accordingly, the damping motor 511 installed in the natural exhaust pipe 510 of the open space 700 is preferably interlocked with the damping motor 262a of the second branch duct 262 to be opened and closed in the same manner. It is preferable that a manual switch is configured to enable the opening and closing of the damping motor 511 in the natural exhaust port 510 so that the air ventilation amount is natural.

In addition, it is preferable that the swelling motor 211 of the suction port 210 forms an interlocking device with the swelling motor 211, which is opened when the supply blower 230 is operated and closed when the supply blower 230 is stopped. The pre-filter is built in and mixed with external air to filter the dust and the like introduced into the suction duct (220).

In addition, the supply blower 230 has a built-in filter 231 for filtering the outside air, it is preferable that the filter 510a is also built in the natural exhaust 510.

It is preferable that the display window is formed in the control unit 400 of the open space to display the room temperature by the built-in temperature detector 401, the automatic mode by the pollution detector 402, and the time mode by the timer 403. .

In addition, the display window is formed in the control unit 420 of the open space to display the room temperature by the temperature detector 421, the set value of the pollution detector 422, the set time of the timer 423, and the like.

FIG. 10 is a view schematically illustrating a connection state with a control unit of a closed space in a unit generation ventilation system using a heat load according to a first embodiment of the present invention.

The temperature detector 263 installed in the first branch duct 261 of the main bedroom of the closed space 600 senses the temperature after the external air passes through the second supply duct 250. When the temperature detected by the temperature detector 263 is higher than the temperature set by the user, the second valve 281 provided on one side of the coil-type ventilation heating pipe 280 is closed to block the hot water circulation. When the temperature is lower than the preset temperature, the second valve 281 of the coil-type ventilation heating pipe 280 opens to allow hot water to flow, thereby controlling the temperature of the air flowing into the room.

The branched duct 261a is a proportional type damper motor 261a that can increase and decrease the air ventilation amount raised to a constant temperature supplied through the first diffuser 271 for each enclosed space 600 by detecting the pollution degree of the indoor air pollution detector. It is preferable to install in). This is because the proportion of air pollution per sealed space, that is, the amount of indoor carbon dioxide is greater than the preset appropriate amount of carbon dioxide, is relatively large, and if the amount of carbon dioxide is less than the predetermined amount of suitable carbon dioxide, the proportional type damper motor (261a) is relatively less heated, resulting in an air ventilation volume. To control.

The timer 413 sets an opening / closing function of the proportional type damping motor 261a installed in the first branch duct 261 for each closed space 600 for each time zone, and then opens the closed space 600 through the first diffuser 271. Unnecessary ventilation volume can be reduced by blocking the air ventilation volume raised to a constant temperature flowing in each space. For example, the user needs to set the timer 413 twice a day (for example, 30 minutes x 2 times) as the user needs a minimum amount of ventilation in a bedroom without people during bedtime or at night. The minimum amount of ventilation is opened to flow in, and at other times, the proportional wave motor 261a is closed to block the flow of air.

Accordingly, the damping motor 511 of the natural exhaust pipe 510 of the enclosed space 600 is interlocked with the proportional type damping motor 261a of the first branch duct 261 and preferably opened and closed in the same manner. It is preferable to configure a manual switch to enable the opening and closing function of the damping motor 511 in the natural exhaust pipe 510 in order to make the external air ventilation amount into natural ventilation.

In addition, the display window is formed in the control unit 410 of the closed space 600 can display the room temperature by the temperature detector 411, the set value of the contamination detector 412, the set time of the timer 413, and the like.

The third embodiment is identical in terms of the components constituting the ventilation system with the first embodiment. Therefore, a description will be given focusing on the flow of air in the ventilation apparatus, which is different from the first embodiment.

Referring to FIG. 11, the outside air is introduced into the room through the suction port 210, and the sucked air moves to the supply blower 230 along the suction duct 220. The outside air passing through the supply blower 230 moves along the first supply duct 340 installed on the side wall of the indoor space. The first supply duct 340 is installed upward along the side wall and is connected to the ceiling of the indoor space. The outside air passing through the first supply duct 340 moves along the second supply duct 350 installed in the ceiling of the indoor space. A coil-type ventilation heating pipe 380 is buried in the upper portion of the second supply duct 350.

The outside air passing through the second supply duct 350 and the hot water circulating in the coil-type ventilation heating pipe 380 exchange heat with each other. The outside air, which has undergone heat exchange with the hot water of the coil-type ventilation heating pipe 380, passes through the first and second branch ducts 261 and 262 and through the first and second diffusers 271 and 272, respectively. The external air heat-exchanged to the closed space 600 and the open space 700 is ejected. The air that has been ventilated indoors is leaked to the outside through the natural exhaust pipe 510 to perform indoor ventilation.

In the third embodiment of the present invention, unlike the first embodiment, the second supply duct 350 and the coil type ventilation heating pipe 380 are installed on the ceiling. In order to install the second supply duct 350 and the coil-type ventilation heating pipe 380 on the indoor floor, it must be installed by a complicated building process such as a concrete floor. Therefore, in terms of construction, the installation process is simplified because the installation of the second supply duct 350 and the coil-type ventilation heating pipe 380 on the ceiling does not require complicated work by the construction process, and the budget is low. There is a saving effect.

In addition, the installation of the second supply duct 350 and the coil-type ventilation heating pipe 380 on the ceiling, compared to the installation of the second supply duct 250 and the coil-type ventilation heating pipe 280 on the floor. 2 Since the length of the supply duct 350 and the branch duct 260 is shortened, there is an advantage that the material can be saved.

The heat insulating material 920 filled in the case 910 made of PVC is preferably made of a material of hard urethane foam or foam rubber insulation, and the second supply duct 350 and the coil type ventilation heating pipe 380. It is preferable to increase the heat exchange efficiency between the hot water and the outside air by filling the conductive material 930 in the junction portion of the).

In addition, during construction, the second supply duct 350 is connected to the flange type, and the coil-type ventilation heating pipe 380 is installed to be fixed to the ceiling by connecting in a union type.

The shape of the coil type ventilation heating pipe 380 is determined according to the characteristics of the indoor space. Specifically, the limited space in which the heat exchange of the room is actively performed to increase the efficiency of indoor ventilation is important, and the coil-type ventilation heating pipe 380 preferably includes four lines. In addition, the use of a circulation method of forcibly circulating hot water by using a circulation pump may reduce the length of the second supply duct 350 and may be installed in a limited space.

In addition, the installation of the coil-type ventilation heating pipe 380 is possible by a four-pipe coil method or a band-shaped coil method, the length of the second supply duct 350 is preferably based on Table 2 below, the unit Depending on the planar condition of the generation, the length of the second supply duct 350 may be increased than the standard shown in Table 2 below.

Dedicated Area (㎡) Ventilation amount (CMH) 2nd supply duct length (M) Coil Type Heating Pipe Length (M) 60 120 5 10 84 160 7 14 128 220 9 18 150 260 11 22

Table 2 is based on when the coil-type ventilation heating pipe is formed in two lines by the band coil method.
