Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a device installed in a living room for ventilation, air conditioning, and hot water supply.

Conventional Technology In recent years, houses have become extremely airtight in order to improve heating, cooling, and soundproofing performance. For this reason, natural ventilation was traditionally provided through gaps in houses, but these gaps are disappearing and ventilation is becoming insufficient. In addition, due to lack of ventilation, moisture accumulates inside houses, causing problems such as mold and condensation. Therefore, ventilation equipment that quickly exhausts contaminated air and moisture from inside homes has become a necessity.

Additionally, air conditioners and water heaters are being installed.

For example, as shown in FIG. 4 and FIG.
03, the living room 102a on the first floor and the living room 102 on the second floor.
A ventilation system 105 was installed in the attic 104 between the rooms 1 and 2, and ventilation was performed through a duct 107 penetrating the outer wall 106 and a vent cap 108 attached to the tip of the duct 1o.

Indoor air supply port 1 facing the ventilation system 105 configured as above.
The indoor air that has been air-conditioned and has effective thermal energy is sucked in from the air conditioner 09, passes through a heat exchanger 110, gives thermal energy to the supplied outdoor air, and is then passed through a duct 107 and a vent cap 108 by an exhaust blower 111. and is exhausted outside. The outdoor air sucked in through the vent cap 108 and the duct 107 receives effective thermal energy from the exhausted indoor air in the heat exchanger 110 by the air supply blower 112, and then receives it from the indoor air supply port 113. Air is supplied to the room. An outdoor unit 114 for air conditioning and a water heater 116 are installed around the building.

Problems to be Solved by the Invention In the conventional ventilation system j05, as shown in FIG. direction) is required. Therefore, lower the ceiling and
We have secured space for 04. Lowering the ceiling gives the living room 102a a feeling of pressure and impairs comfort, and the ceiling of any living room cannot be lowered.
Since the installation location is limited, there is a problem in that it cannot always be installed in a position where sufficient ventilation effects can be obtained. In addition, although ducts are installed in the ceiling, it is not possible to effectively utilize the thermal energy in the attic or under the floor.Furthermore, the only function is ventilation, and a separate air conditioner is required for heating and cooling. There were also issues that needed to be addressed. Additionally, outdoor units 114 of air conditioners and water heaters 116 with different appearances are installed around the building, resulting in a loss of aesthetics.

The present invention takes into consideration the above-mentioned conventional problems, and has a large degree of freedom in the installation location of the ventilation system, allowing it to be installed in any location to obtain a sufficient ventilation effect, excellent interior and exterior design, and The purpose of the present invention is to provide an air-conditioning, ventilation, and hot-water supply system that utilizes effective thermal energy in the roof and attic, and has energy-saving effects as well as air-conditioning and heating functions and hot-water supply functions.
