Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly has an air conditioner for air-conditioning a living room such as a bathroom, an air supply means for supplying outdoor air, and an exhaust means for exhausting indoor air. The present invention relates to an air conditioning system in which a heat exchanger that exchanges heat is connected by the same exhaust duct.

[0002]

2. Description of the Related Art Conventionally, this type of air conditioning system mainly comprises an air conditioner for air conditioning a living room such as a bathroom, an air supply means for supplying outdoor air, an exhaust means for exhausting indoor air, and an outdoor air supply means. There is known a configuration in which a heat exchanger for exchanging heat with indoor air is piped with separate ducts.

[0003]

However, in the above-described conventional apparatus, heat cannot be exchanged between the air in a bathroom having abundant heat energy by a hot water shower or the like and heat energy after bathing. Therefore, from the viewpoint of heat recovery of the entire living room. Has a problem that waste heat is large and heat is exhausted unnecessarily.

[0004] Also, since the ducts are separately piped,
There were also problems such as high cost of materials and long construction time. Furthermore, since it is necessary to provide a large number of through holes in the structural part of the building, it is necessary to reinforce the structure, and there is a problem that the construction is troublesome.

[0005] Further, if the exhaust ducts are made the same, if the air in the bathroom is humid, dew condensation occurs in the heat exchanger, so that the heat exchange element deteriorates and the heat exchange element becomes moldy. There were also problems such as becoming difficult.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is mainly to ventilate a living room such as a bathroom and to exchange heat between indoor air and outdoor air. It is an object of the present invention to provide an air conditioning system that can exchange heat energy of the air and heat exhaust ducts.

[0007]

In order to achieve the above object, the present invention provides an air conditioner for mainly air-conditioning a living room such as a bathroom, and an air supply means for supplying outdoor air. An air-conditioning system having exhaust means for exhausting indoor air, and a heat exchanger for exchanging heat between outdoor air and indoor air through the same exhaust duct, and exhausting the air to the outside; It is characterized by having a control function of interlocking with the container.

Therefore, with this configuration,
It becomes possible to simultaneously ventilate the bathroom and several other living rooms, and also to control the supply and exhaust of the heat exchanger in accordance with the exhaust of the bathroom. Since the pressure is not reduced, it is possible to ventilate the humid air in the bathroom without flowing into an adjacent room or the like and forming dew.

Further, if the exhaust duct for exhausting indoor air is provided with a bypass, a damper switching unit arranged at a position capable of switching between the bypass and the exhaust path, and one or more air quality sensors, The heat energy can be exchanged between the heat energy from the shower etc. in the bathroom and the heat energy after bathing. By switching to the bypass by the damper switching unit in the duct path, heat can be exchanged in the heat exchanger without dew condensation.

[0010] The air conditioner may further include a ventilator for supplying air in the bathroom and exhausting the air outside, a circulating means for supplying air in the bathroom and exhausting the air again into the bathroom, and a heating means inside the circulating air passage. A bathroom ventilator / heater provided with a heater can heat the bathroom and dry the interior of the bathroom. Also, by putting clothes on the bathroom, the bathroom can be made into a clothes drying room.

Further, the heating means of the bathroom ventilation heater includes:
If an electric heater is used and the air supply duct and the exhaust duct are made of non-combustible material, it is possible to comply with the Fire Service Law for bathroom dryers incorporating an electric heater.

Further, if at least one of the one or more air quality sensors is located in the bathroom, it is possible to detect the air in the bathroom, and to bypass the path to the heat exchange element depending on the state of the air in the bathroom. By switching, it becomes possible to prevent condensation and the like in the heat exchanger without passing humid air or the like in the heat exchanger, and to perform ventilation.

Further, if at least one of the one or more air quality sensors is a dew sensor in the bathroom, the damper is switched to prevent heat exchange only when the bathroom is dewed. Therefore, humid air does not flow into the heat exchange, and the life of the product can be extended.

Further, if at least one of the one or more air quality sensors is a humidity sensor in a bathroom,
Due to the humidity of the air in the bathroom, the damper is switched so that heat does not pass through, so that humid air does not flow into the heat exchange more, so that the life of the product can be extended.

If the one or more air quality sensors are provided in the air conditioner, the size of the air conditioner can be made compact, so that the work is simplified and the work can be performed in a short time. .

If the bypass and damper switching unit are provided in the vicinity of the heat exchanger, the piping of the heat exchanger can be made compact, so that the construction can be simplified and the construction can be performed in a short time. Inspection becomes easier.

Further, by providing the one or more air quality sensors in the heat exchanger, the size of the heat exchanger can be made compact, so that the construction is simplified and the construction can be performed in a short time. Becomes possible.
