Abstract

To provide a system that provides a house with first class ventilation and air conditioning throughout the building without ventilating each room directly with the outside nor use a long air supply duct and an underfloor space, an inter-story space or an attic space as a ventilation space in order to improve cleaning of supplied air, costs, maintainability, and sound insulation.SOLUTION: A first class ventilation device is nearby a main living room, and an air supply port and an air-conditioning device are in the main living room. Air-conditioned ventilation air flows to a sanitary room with an exhaust port, and the air-conditioned ventilation air which is flowing is diverted by a non-heat exchange ventilation fan in a wall of a sub-living room to reach respective rooms, thereby covering all living rooms.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] This invention relates to a 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 conditioning devices such as air conditioners to 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 eliminate the problems of 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 is a system in which air is supplied and exhausted from one ventilation unit and associated air conditioning unit through ducts to each room, but the ducts are long and numerous, and as they are not usually cleaned, they become contaminated over time. In particular, contamination such as dust and mold that accumulates inside the air supply ducts can cause health problems for the residents. As the ducts are long and thin and curved, cleaning the inside of the ducts is difficult, and replacing them is also difficult. In addition, installing ducts in each room is costly.

[0004] There are also systems that, instead of using ducts, install ventilation and air conditioning equipment in the space under the floor, between floors (ceiling), or in the attic, and ventilate and condition these spaces, then supply air from these spaces to each room. However, these spaces tend to become stagnant and require strong wind power, and furthermore, general cleaning and other maintenance of these spaces is difficult because people cannot easily enter these spaces.

[0005] Installing ventilation equipment and air conditioning equipment that intakes and exhausts air to the outdoors in every room does not require ducts, but outdoor noise will enter the rooms directly through the ventilation openings that supply and exhaust air to the outdoors. In addition, multiple ventilation equipment and air conditioning equipment are required for each room, which is costly. In airtight, highly insulated homes, the air conditioning capacity is sufficient to cover all rooms with just one or two air conditioning units, so multiple air conditioning units are overkill and make temperature control more difficult in small rooms.

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

[0008] Here, the main room is the room in a house that is large and where many people spend a lot of time, typically the living room and dining room, and where the air needs to be cleanest, and the other rooms are secondary rooms. Also, spaces that are primarily used for passing through, including staircases and entrance halls, typically hallways, are called passage spaces. Toilets, bathrooms, dressing rooms, and laundry and drying rooms are collectively called sanitary rooms. A first-class ventilation system is installed in the main room or a room adjacent to the main room, and a first-class ventilation system Air intakes from these rooms open into the main room and adjacent rooms, and air is drawn in from outside. Exhaust outlets open in one or more sanitary rooms, and the exhaust air passes through a duct from the exhaust outlet and is discharged outdoors by a first-class ventilation system. The doors and walls along the route from the room with the air intake to the room with the exhaust outlet have ventilation structures such as undercuts and louvers. There are non-heat exchange ventilators that span the walls between each ancillary room and the passage space or main room. The air conditioning unit is located in the main room or in a room adjacent to the main room.

[0009] Fresh air from outside is conditioned in the main room, which has an air intake and air conditioning unit, and the conditioned air flows from there to the sanitary room, which has an exhaust vent. On the way there, the conditioned air is diverted to each room by non-heat exchange fans in the walls of each sub-room, covering all the rooms. Effect of the Invention

[0010] With this method, no intake duct is required, and even if one is, a short one is sufficient, eliminating the problems mentioned above related to ducts. Air conditioners and first-class ventilation equipment are installed in the space under the floor, between floors (attic), or in the attic, but because no air is ventilated into these spaces, no maintenance of these spaces is required. Basically, one first-class ventilation equipment and one air conditioner can be used to serve the entire residence. The only thing that needs cleaning is the associated filters.

[0011] Noise from outside travels through the complex internal structure of the first-class ventilation system and is diffused throughout the spacious main room, and then passes through the inside of the ventilation fan in the sub-room, where the volume is reduced, so noise is less likely to travel inside the building. Odors from toilets and humid air from bathrooms and drying rooms can be preferentially discharged to the outdoors, while fresh, conditioned air can be provided preferentially to the main living space where people are most active. Air conditioning equipment is not special, but is simply the usual household equipment installed in the usual way, so costs are low. [Brief description of the drawings]

[0013] As shown in Figure 1, when a living room / dining room 1 is adjacent to a kitchen room 2, it is desirable to install a first-class heat exchange ventilation system 10 in the ceiling of the kitchen room 2. A short air intake duct 12 extends from the first-class ventilation system 10, and an air intake port 120 opens in the ceiling of the living room / dining room 1 and kitchen room 2, and air from outside is supplied. As shown in the figure, the air intake duct 12 can be short. An exhaust port 140 opens at least in the ceiling of the toilet 3, and preferably also in the bathroom 5, and the exhaust port 140 is connected to the first-class heat exchange ventilation system via an exhaust duct 14 in the ceiling. It is connected to 10 and the exhaust air is discharged outdoors. Along the route from the room with the air intake vent 120 to the room with the exhaust vent 140 in the indoor space, there is an undercut in the interior door or a louver in the door or wall. That is, in Figure 1, such ventilation structures are present in the doors or nearby walls between the living / dining room 1 and the hallway 8, between the toilet 3 and the hallway 8, between the dressing room 4 and the hallway 8, and between the bathroom 5 and the dressing room 4. There are non-heat exchange ventilation fans 30 spanning the walls between each of the secondary rooms 6, 7 and the hallway 8. And there is an air conditioning unit 20 in the living / dining room 1.

[0014] The non-heat exchange ventilation fan 30 installed in the secondary rooms 6 and 7 may be a non-heat exchange type simultaneous supply and exhaust ventilation fan 31 (Figs. 2 and 3), or a simple supply fan 32 and exhaust fan from a ventilation structure (Figs. 4 and 5). The ventilation structure may be an undercut 40 or a louver 41, and the louver may have a soundproofing effect using sound-absorbing material in a louver structure.

[0015] Fresh air from outside is conditioned in the living / dining room 1, which has an intake vent 120 and an air conditioner 20. The conditioned air flows from the undercut of the door of the living / dining room 1 to the corridor 8, passes through the undercut of the door of the dressing room 4 via the corridor 8, and flows to the bathroom 5, which has an exhaust vent, where it is exhausted. On a separate route, the air passes through the undercut of the door of the toilet 3 from the corridor 8 and is exhausted from the exhaust vent 140 in the toilet 3. The exhaust air is heat exchanged with the intake air in the first-class heat exchange ventilator 10 and exhausted to the outdoors. The conditioned air is diverted to each of the secondary rooms 6, 7 by the non-heat exchange ventilator fans 30 in the walls between the corridor 8 and each secondary room 6, 7, midway along the flow of the conditioned air, so that all the rooms are covered.

[0016] If the total floor area of ​​a house is large and a type 1 ventilation system is required on each floor, a system similar to the above will be installed on each floor. For example, on the second floor, which has no living room or bathroom, a type 1 ventilation system is installed in the main living room (such as a study) on the second floor or in a walk-in closet adjacent to the main living room, with an air intake opening from there via a short duct and an exhaust opening in the second-floor toilet. There are non-heat exchange ventilation fans in the walls between each secondary living room on the second floor and the second-floor hallway or main living room. The air conditioning unit is in the main living room on the second floor. [Explanation of symbols]
