Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a ventilation air conditioning unit having air conditioning and ventilation functions for apartment buildings and the like.

BACKGROUND OF THE INVENTION Conventionally, ventilation and air conditioning in housing complexes (condominiums, etc.) are often carried out by hanging the air in the ceiling as shown in FIG. That is, a main body 2 of the ventilation air conditioning unit is installed in the attic 1 of an apartment complex by a hanging port 3, and an intake fan 4 and an exhaust fan 6 are installed in the main body 2.
It also includes an air conditioning blower 6 and a heat exchanger 7 for passing cold and hot water and refrigerant, and a duct 8 drawn from outside.
Although not shown, a return duct is provided to return indoor air, and on the other side, air is blown into each room via an indoor air outlet duct 9 which serves as an outlet for indoor air. That's what I do.

Although not shown, ducts for ventilation, such as outdoor exhaust ports for exhausting indoor air, and multiple ducts for branching conditioned air to each room are installed to improve ventilation. It was for air conditioning.

l Note that Kuzu is an inspection hole provided in the ceiling surface 1o.

Problems to be Solved by the Invention In such a conventional configuration, depending on the apartment complex, the ceiling space 1 is narrow and other pipes may be installed, making it difficult to install and hang the main body 2. In addition, since the ducts are connected from both sides or all four sides of the main body, this duct construction is also difficult, and in some cases, there is a problem in that it becomes impossible to suspend or install the main body 2. .

The present invention solves these problems, and aims to provide a ventilation air conditioning unit that is easy to construct and allows for duct work even if the inside of the attic is narrow.

Means for Solving the Problem In order to solve this problem, the present invention has a ventilation air conditioning function that includes a total heat exchanger, a heat exchanger, an intake fan, an exhaust fan, and an air conditioning blower. The unit is provided with an outdoor suction port to which a duct is connected, an outdoor exhaust port, an indoor air outlet, and a return suction port that returns from each room on the top surface of the unit, and air is taken in from the outdoor suction port. an intake flow path that passes through the fan, the total heat exchanger, and reaches the air conditioning blower; an exhaust flow path that passes through the return suction port, the exhaust fan, the total heat exchanger, and reaches the outdoor exhaust port; The air conditioning flow path is formed from the return suction port, passes through the air conditioning blower, passes through the heat exchanger, and reaches the indoor air outlet.

Operation With the above configuration, the outdoor air intake, outdoor exhaust, return air intake from each room, and indoor air outlet that blows out to each room are connected by ducts, and these are gathered on the top of the main body. The outside air that flows in from the outdoor intake port passes through the intake opening from the intake path, passes through the total heat exchanger by the intake fan, flows through the intake flow path, and supplies outside air indoors, and the air that flows in through the return intake port is exhausted. A part of the room air is exhausted by the fan through the total heat exchanger and through the exhaust flow path, while the air flowing from each room through the return suction port is passed through the heat exchanger by the air conditioning blower. The cooled or heated air is then blown out into each room through ducts.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 3.

Inside the main body 41, there are a total heat exchanger 52 for recovering heat by exchanging heat between intake and exhaust, a heat exchanger 46 for flowing a medium and performing air conditioning, an intake fan 6o, and an exhaust fan 51.
It is equipped with a blower 44 for air conditioning, and is configured as a unit having a so-called ventilation air conditioning function.

The characteristic configuration of this embodiment is that the duct connection ports are provided in a concentrated manner on the top surface 69 of the main body 410. That is, the top surface 69 of the main body 41 has an outdoor suction port 53 formed to be able to connect a duct, an outdoor exhaust gas 067, a plurality of indoor air outlets 48, and a return suction port 46 that returns from each room.
This is provided.

In addition, an intake fan 6 is installed inside the main body 41 from an outdoor suction port 53.
〇-Total heat exchanger 62-Air conditioning blower 44-Indoor air outlet 4
8, an exhaust flow path B from the return suction port 46 to the exhaust fan 61 - total heat exchanger 62 - outdoor exhaust port 67, and an air conditioning blower 44 from the return suction port 46
An air conditioning flow path C from the heat exchanger 43 to the indoor air outlet 48 is formed.

In the above configuration, since the outdoor suction port 63 that connects the duct, the outdoor exhaust port 67, the plurality of indoor air outlets 48, and the return suction port 46 are arranged centrally on the top surface 59 of the main body 41, The work of connecting the ducts is easy to perform, and even when the main body 41 is installed in a dead space, for example, the work of connecting the ducts is easy, and the duct piping is also organized for a better appearance.

Note that in the main body 41, the air conditioning blower 44°, the intake fan 5Q, and the exhaust fan 61 are operated, and the medium is not allowed to flow into the heat exchanger 43, but the return air that has flowed in through the return suction port 4e is The air is cooled or heated by a heat exchanger 43 through a blower 44, and then blown out through each indoor air outlet 48 to perform so-called indoor air conditioning. In addition, outside air flows in from the outdoor suction port 63, passes through the intake fan, and then passes through the exchanger 62, and then passes through the air conditioning blower 44. It passes through a heat exchanger 43, is air-conditioned, and is supplied as so-called fresh air to each room from an indoor outlet 48. Furthermore, after the air flowing in from the return suction port passes through the air conditioning blower 44, a part of the air is attracted by the exhaust fan 6, passes through the total heat exchanger 52, and is exhausted from the outdoor exhaust port 57.

Effects of the Invention As is clear from the description of the above embodiments, the present invention has an outdoor intake port, an outdoor exhaust port, a return intake port on the top surface of the main body,
An indoor air outlet is provided in each room, and each room is connected only by a duct inside the attic. Air is drawn into the main body from the outdoor air inlet, passes through the air intake fan, passes through the total heat exchanger, and reaches the air conditioning blower. A flow path, an exhaust flow path that passes from the return suction port, an exhaust fan, and a total heat exchanger, and an air conditioning flow path that runs from the return suction port, passes through an air conditioning blower, passes through the heat exchanger, and reaches the indoor air outlet. Because of this, it is only necessary to place the duct in the attic from the top of the main unit, and it can be easily hung and installed on the floor without taking up space in the attic. This has the advantage that the duct can be installed even if the height inside the attic is low.
