Description

[Technical field]

[0001] This invention relates to a ductless first-class ventilation and air conditioning system for residential facilities. [Background technology]

[0002] Homes require the ability to maintain a comfortable room temperature using air conditioners and other air conditioning devices that regulate the indoor temperature, and airtight homes can easily maintain that room temperature, but at the same time, a certain amount of ventilation with the outdoors is necessary to prevent problems such as carbon dioxide buildup and sick house syndrome. In ventilation systems, those that actively use fans to supply and exhaust air are called type 1 ventilation, and can provide a steady, appropriate amount of ventilation. Furthermore, type 1 ventilation includes heat exchange ventilation, which transfers heat between the air exhausted from inside the room to the outside and the air supplied from the outside to the room, making it possible to reuse the energy of the conditioned air and send it indoors, which is important for saving energy in air conditioning.

[0003] In residential first-class ventilation and whole-house air conditioning systems, there are systems that use ducts to supply and exhaust air from a single air conditioner or ventilation device to each room, but contamination from dust and mold that accumulates inside the ducts can be a problem. Cleaning the inside of the ducts is difficult, and running ducts to every room requires equipment and construction costs. Due to cost constraints, it is sometimes not possible to install supply and exhaust vents in every room. There are also methods that use ducts only for supply and exhaust, and use door undercuts, door louvers, or atriums for the other, but this reduces the soundproofing performance between rooms indoors.

[0004] There are also systems in place that install air conditioners and ventilation equipment under floors, between floors, and in the attic, and then ventilate these spaces and supply air from these spaces to each room, but these spaces require a high level of insulation and airtightness, and because there are many obstacles in these spaces, they require strong wind power, and either the intake or exhaust is done through ducts. Overall cleaning and other maintenance of these spaces is difficult because it is not easy for people to enter these spaces.

[0005] One option, instead of air conditioning the entire building, is to install a ventilation system and air conditioner in each room, but outdoor noise would enter the room directly through the ventilation openings that supply and exhaust air to and from the outside. Also, multiple ventilation systems and air conditioners would be required for each room. In a highly airtight, highly insulated house, the air conditioning capacity is sufficient with just one or two air conditioners, so multiple air conditioners are overkill and would actually make it difficult to regulate the temperature in small rooms.

[0006] [Patent Document 1] Patent 5094894 [Patent Document 2] Patent Publication No. 2012-21758 [Patent Document 3] Patent 6211675 Summary of the Invention [Problem to be solved by the invention]

[0007] The objective is to build a system that realizes first-class ventilation and central air conditioning for a house without direct ventilation between each room and the outdoors, without using ducts, and without using underfloor spaces, inter-floor spaces, or attic spaces as ventilation spaces, in order to improve costs, ease of maintenance, and soundproofing performance. [Means for solving the problem]

[0008] An indoor space such as a corridor or entrance hall that connects each room and acts as a passageway for people to move between the rooms is called a passage room. For example, in a house with a hallway leading from the entrance hall and each room connected to the hallway, the entrance hall and the hallway are passage rooms. In a house with no hallway and a large entrance hall with a living room and each room connected to the hallway, the entrance hall is a passage room. In a house with no hallway and each room connected to the living room, the living room serves as both a passage room and a living room.

[0009] The first-class ventilation system is installed in the passage room, and the passage room is ventilated by supplying and exhausting air between the passage room and the outdoors using either heat exchange or non-heat exchange methods. An air conditioner is also installed in the passage room to regulate the temperature inside the passage room. Between the passage room and the rooms there is an inter-room ventilation duct and an inter-room ventilation fan that can change the wind direction and does not exchange heat. The fan of the inter-room ventilation fan supplies air from the passage room to the rooms and exhausts air from the rooms to the passage room, and the supply and exhaust air are simultaneous and equal in volume. By installing this inter-room ventilation duct and inter-room ventilation fan in each room, each room can be ventilated and air-conditioned.

[0010] There are many variations in inter-room air ducts and inter-room ventilation fan fixtures. There is one-hole, one-fixture system where the inter-room air duct has one hole through which the supply and exhaust ducts pass (inter-room supply and exhaust duct), with air being supplied and exhausted via one fixture, and there is also a two-hole, two-fixture system where the inter-room air duct has two holes, each with a ventilation fan fixture. Two-hole, one-fixture systems are also possible. There are also many variations in ventilation fan fixtures with variable wind direction, as shown below, and the appropriate one is installed for each room.

[0011] In the up and down air direction system for inter-room ventilation fans, in the one-hole, one-apparatus system, a single ventilation fan is divided by a partition, and each fan has an upward fan with its air axis (the axis of the air direction, including both positive and negative, i.e., the direction of exhaust and intake. It can be the rotation axis of a propeller fan or the direction of the exhaust air tunnel) facing upward toward the room, and a downward fan with its air axis facing downward toward the room. The upward and downward fans have opposite air directions and are responsible for either supplying or exhausting air. The inter-room air intake and exhaust duct is a pipe that passes through the wall, and the inside is divided into upper and lower parts by a partition, and the ventilation hood is also divided into upper and lower parts. The top of the ventilation hood opens upwards, and the bottom of the ventilation hood opens downwards. The space for the upward fan is connected to the top of the pipe and the top of the ventilation hood, and the space for the downward fan is connected to the bottom of the pipe and the bottom of the ventilation hood. An inter-room ventilation fan with an up and down air direction is installed on the indoor wall that separates the passage room from each room, and the fan blows air into the rooms. It supplies and exhausts air between the passage room and the room. The fan is a propeller fan, and its rotation direction can be reversed, and the rotation of the upward and downward fans can be reversed simultaneously by using an interlocking switch to reverse the direction of airflow. In summer, air is supplied from the passage room to the room by the upward fan, and the cold air from the passage room is blown upward into the room, making it easier for cold air to circulate throughout the room. Warm air exhausted from the room to the passage room is sucked in from below by the inter-room ventilation fan device by the downward fan and blown downward into the passage room, making it easier for warm air to circulate in the passage room. In winter, the interlocking switch can be used to reverse the rotation of the fan in both the upward and downward directions, so that air is supplied from the passage room to the room by the downward fan, and warm air from the passage room is blown downward into the room, making it easier for warm air to circulate throughout the room. Cold air exhausted from the room to the passage room is sucked in from above by the inter-room ventilation fan device by the upward fan and blown upward into the passage room, making it easier for cold air to circulate in the passage room.

[0012] Another type of inter-room ventilation fan (upper and lower separation type) is the two-hole, two-appliance type, which has an upper ventilation channel in which the ventilation channel is located at the top of the wall separating the passage room from the room, or an air vent in the ceiling between the passage room and the room, and a lower ventilation channel in which the ventilation channel is located at the bottom of the wall separating the passage room from the room, or an air vent in the floor between the passage room and the room, and a ventilation channel is located between them (if there is an air vent in the wall, there is an air vent above the ceiling, and if there is an air vent on the floor, there is an air vent below the floor). There are inter-room ventilation fans with built-in propeller fans in each of the upper and lower ventilation channels, and the fans of the upper and lower inter-room ventilation fans blow air in opposite directions, so Each is responsible for supplying and exhausting air, and the supply and exhaust volumes are equal. The rotation of the fans can be reversed, and by using an interlocking switch, the rotation of the fans in the upper and lower room ventilation equipment can be reversed at the same time to reverse the air supply direction. In summer, the upper air passage exhausts air from each room to the passage room, and the lower air passage supplies air from the passage room to each room, and in winter, the interlocking switch is switched to the opposite, so that the upper air passage supplies air from the passage room to each room, and the lower air passage exhausts air from each room to the passage room. As a result, in summer, cold air that tends to accumulate at the bottom of the passage room is sent to each room via the lower air passage, and in winter, warm air that tends to accumulate at the top of the passage room is sent to each room via the upper air passage.

[0013] As an alternative, a two-hole, one-fixture system with separate top and bottom ventilation is also possible, with an inter-room ventilation fan in the upper ventilation duct as above, and a different configuration in which the lower ventilation duct has only a door undercut or a louver at the bottom of the door, and no ventilation fan. The upper inter-room ventilation fan is the same as above, and the propeller fan can be reversed with a switch. In summer, the upper inter-room ventilation fan in the upper ventilation duct exhausts air from each room to the passage room, and the lower ventilation duct passively supplies air from the passage room to each room, and in winter, the switch is switched so that the upper inter-room ventilation fan in the upper ventilation duct supplies air from the passage room to each room, and the lower ventilation duct passively exhausts air from each room to the passage room. This configuration is suitable for small rooms where soundproofing is not necessary in order to keep costs down.

[0014] In another type of inter-room ventilation fan (louver type), the two-hole, two-furniture type, there are two air passages at the top of the wall separating the passage room from the room, each with a built-in fan, and the two inter-room ventilation fans blow air in opposite directions, one supplying air from the passage room to the room and the other exhausting air from the room to the passage room. There are louvers on the call side of the two inter-room ventilation fans, making it possible to change the blowing direction up and down. In summer, the supply air from the passage room to each room blows upward, and the exhaust air from each room to the passage room blows downward, and in winter, the opposite is done, with the supply air from the passage room to each room blowing downward, and the exhaust air from each room blowing upward to the passage room. In this case, the fans can be propeller fans or fans that cannot be reversed, such as centrifugal fans.

[0015] Also, for the two-hole, two-fixture type of inter-room ventilation equipment with up-down airflow, a variation is possible in which instead of using the partition as mentioned above, it is divided into two fixtures, each with an upward fan and a downward fan.Also, for the one-hole, one-fixture type of inter-room ventilation equipment with a louver, a variation is possible in which the two inter-room ventilation equipment mentioned above are combined into one fixture with a partition. Effect of the Invention

[0016] With this method, no ducts are required, or if any are required, a short one is sufficient (if the inter-room ventilation path is installed in the wall, no ducts are required, if the vent is installed in the ceiling, a short duct that passes above the ceiling and crosses the wall is sufficient, and if the vent is installed on the floor, a short duct that passes under the floor and crosses the wall is sufficient), eliminating the above-mentioned problems related to ducts. Even if an air conditioner or first-class ventilation device is installed in the space under the floor, between floors, or in the attic, the entire space is not ventilated, so there is no need to maintain that space. Basically, one first-class ventilation device and one air conditioner can cover the entire space. The only cleaning that needs to be done is the associated filter.

[0017] Noise from the outdoors reaches each room through the first-class ventilation system in the passage room, is diffused into the wide space of the passage room, and then passes through the inter-room ventilation fans, resulting in three stages of reduction, making it difficult for noise to reach each room. Sound from one room is also reduced by passing through two inter-room ventilation fans.

[0018] Generally, ventilation fans have a small air volume and cannot change the direction of the airflow, but the air volume required for air conditioning is greater than that required for ventilation because it circulates air with a temperature difference. Furthermore, increasing the air volume results in increased noise. With the vertical separation method for inter-room ventilation fans, ventilation corresponds to the temperature difference between the passage room and the top and bottom of each room, making it easier to air-condition each room. In other words, in summer, the cold air that tends to accumulate at the bottom of the passage room is sent to each room through the lower air passage, and the warm air remaining at the top of each room is sent to the passage room through the upper air passage. In winter, the warm air that tends to accumulate at the top of the passage room is sent to each room through the upper air passage, and the cold air remaining at the bottom of each room is sent to the passage room through the lower air passage. This allows the conditioned air in the passage room to be effectively transferred to each room even with a small air volume.

[0019] With inter-room ventilation fan equipment using the up-down airflow direction method or the louver method, in the summer, cool air from the passage room is blown upwards into the room, making it easier for the cool air, which is dense and tends to remain at the bottom, to spread throughout the room. The cool air circulates within the room and returns as warm air, which is blown downwards into the passage room, making it easier for the warm air, which is less dense and tends to remain at the top, to circulate within the passage room. In the winter, the opposite is done, so the warm air from the passage room is blown downwards into the room, making it easier for the warm air to spread throughout the room. The warm air circulates within the room and returns as cool air, which is blown upwards into the passage room, making it easier for the cool air to circulate within the passage room.

[0021] In the overhead layout diagram of the entire system in Figure 1, the passage room 1 is the space that stretches from the entrance hall to the corridor. A first-class ventilation device 10 is installed indoors, such as under the ceiling of the passage room 1, or under the floor or above the ceiling, and an indoor air supply vent 13 and an indoor exhaust vent 14 open from the first-class ventilation device 10 directly to the passage room 1 or to the floor or ceiling. An outdoor air supply vent 11 and an outdoor exhaust vent 12 open to the outdoors on the outer wall of the passage room 1 or on the outer wall under the floor or above the ceiling. It is desirable to have soundproof hoods installed on the outdoor air supply and exhaust vents 11 and 12. It is desirable for the first-class ventilation device 10 to have heat exchange properties. Furthermore, an air conditioner or other air conditioner 20 is installed in the passage room, and the outdoor unit 21 of the air conditioner is installed outdoors. Furthermore, inter-room ventilation fan devices 30 are installed to supply and exhaust air between the passage room 1 and each room 2, 3, and 4.

[0022] In the one-hole, one-equipment type, the up-down airflow direction type between-room ventilators is as shown in Figures 1, 2 and 3. There is an inter-room air supply and exhaust duct in the indoor wall (the wall above the door in Figure 2) separating the passage room 1 from rooms 2, 3 and 4. On the room side of the duct, there is a non-heat-exchangeable inter-room ventilator 30 (Figure 3a), and on the passage room side, there is a ventilation hood 301 (Figure 3b). The inside of the inter-room ventilator 30 is divided by a partition (Figure 3c), and each has an upward fan 302 with its airflow axis facing upward toward the room side, and a downward fan 303 with its airflow axis facing downward toward the room side. The upward and downward fans blow air in opposite directions, and are responsible for either supplying or exhausting air. The inside of pipe 304, which runs through the wall as an inter-room supply and exhaust passage, is divided into upper and lower parts by a partition, and ventilation hood 301 is also divided into upper and lower parts. The top of ventilation hood 301 opens upwards, and the bottom of ventilation hood 301 opens downwards. The space of upward fan 302 is connected to the top of pipe 304 and the top of ventilation hood 301, and the space of downward fan 303 is connected to the bottom of pipe 304 and the bottom of ventilation hood 301.

[0023] Air is supplied and exhausted simultaneously at equal volumes between the passage room and each room. The fans are propeller fans whose rotation direction can be reversed, and an interlocking switch can be used to simultaneously reverse the rotation of the upward and downward fans, reversing the airflow direction. As shown by the dotted arrows in Figure 3c, in summer, air is supplied from the passage room to each room by upward fan 302, and cool air from the passage room is blown upward into the rooms, making it easier for cool air to circulate throughout the rooms. Warm air exhausted from the rooms to the passage room is blown upward by downward fan 303, which blows air from below to the inter-room ventilation fan. Warm air is sucked into the equipment and sent downward to the passage room, making it easier for the air to circulate in the passage room. In winter, the opposite is true; the rotation of the upward and downward fans is reversed with an interlocking switch, and air is supplied from the passage room to each room by the downward fan 303, while warm air from the passage room is sent downward into the rooms, making it easier for the warm air to circulate throughout the rooms. Cold air exhausted from the rooms to the passage room is sucked in from above by the inter-room ventilation fan equipment by the upward fan 302 and sent upward to the passage room, making it easier for the cold air to circulate in the passage room.

[0024] As shown in Figures 4 and 5, the two-hole, two-apparatus system with upper and lower separation of room-to-room ventilation fan equipment has ventilation passages at the top and bottom of the wall separating the passage room and the room, and there is an upper room-to-room ventilation fan equipment 310 and a lower room-to-room ventilation fan equipment 311 each with a built-in propeller fan 314. The upper and lower fans blow air in opposite directions, and are responsible for supplying and exhausting air, respectively, with the same amount of supply air and exhaust air. The rotation of the fans can be reversed, so the blowing direction can be changed, and the upper and lower fans can be reversed simultaneously by using the interlocking switch 312. In summer, the upper inter-room ventilator 310 exhausts air from each room to the passage room, and the lower inter-room ventilator 311 supplies air from the passage room to each room, and in winter, the two are switched over by an interlocking switch 312 so that the upper inter-room ventilator 310 supplies air from the passage room to each room, and the lower inter-room ventilator 311 exhausts air from each room to the passage room. The upper inter-room ventilator 310 and the lower inter-room ventilator 311 have the same structure, and it is desirable to install sound absorbing material 315 in the ventilation path and a soundproof hood 313 on the passage room side of the inter-room ventilator.

[0025] In the two-hole, one-fixture system with an upper and lower separation between-room ventilator fixture, as shown in Figure 6, there is an upper air passage at the top of the wall separating the passage room from the room, where there is an upper inter-room ventilator fixture 310 with a built-in propeller fan 314. The rotation of the fan can be reversed, allowing the direction of air to be changed. An undercut 316 is provided in the door. In summer, the upper inter-room ventilator fixture 310 exhausts air from each room to the passage room, and the undercut in the door passively supplies air from the passage room to each room. In winter, the opposite is true, with the upper inter-room ventilator fixture 310 supplying air from the passage room to each room, and the undercut in the door passively exhausts air from each room to the passage room.

[0026] As shown in Figures 7 and 8, the two-hole, two-apparatus system with louver between-room ventilators has two air passages at the top of the wall separating the passage room and the room, each of which has an inter-room ventilator 33 with a built-in fan 332. The two inter-room ventilators are installed facing in opposite directions, with the air blowing in opposite directions, one supplying air from the passage room to the room and the other exhausting air from the room to the passage room. The supply and exhaust volumes are the same. The two inter-room ventilators 33 have louvers 331 on the call side 330, making it possible to change the air blowing direction up and down. Inside there is a fan 332 and sound absorbing members 333, 334. The intake side 336 of the inter-room ventilation fan device 33 is bent to have an intake port 335. In summer, the direction of supply air from the passage room to each room is upward, and the direction of exhaust air from each room to the passage room is downward, and in winter the opposite is done, with the direction of supply air from the passage room to each room downward, and the direction of exhaust air from each room to the passage room upward. In this case the fan 332 can be a propeller fan or a centrifugal fan.
