The main body casing 4 constituting the outer shell of the main body 1 is basically configured in a box shape that can be placed on an installation plane such as the floor of a building without the need for a pedestal 2. Inside the main body gauging 4, there is a first air passage 8, which passes outdoor (mostly outdoor) air, that is, outside air, sent through the duct 5, and which starts at the air intake 6 and ends at the air supply blow-off lower. , and a second air passage 11 that starts at the indoor air intake port 9 and ends at an exhaust outlet 10 connected to the outside via the duct 5 are independently constructed. A part of the middle of the first air passage 8 and the second air passage 11 is a total heat exchanger 1 built into the main body casing 4.
The structure is such that total heat exchange is possible through each of the two ventilation passages.

In the first air passage 8 upstream of the total heat exchanger 12, there is interposed an air conditioning coil 13 that forms cooling air or heating air by conducting a cooling heat medium or a heating heat medium. A two-wire circulation blower 14 that forms an air flow in the first air path 8 is provided in parallel in the first air path 8 near the supply air blowing lower on the upstream side of the air conditioning coil 13. .

The first air passage 8 on the suction side of the two-wire circulation blower 14 branches into two, and the outlet side communicates with two individual supply air blowing lowers installed side by side. That is, the first air passage 8 is divided into two systems on the exit side. Further, between the total heat exchanger 12 and the air conditioning coil 13 in the first air passage 8, there is a third air passage 15, one end of which opens at the front of the main body 1, and the other end of which takes indoor air. have been contacted. This third air passage 15
All the outlet ends and inlet ends of the ventilation system except for the air supply port 6, the two supply air blowout lowers, the indoor air intake port 9, and the exhaust outlet 10 are all located at the top of the main body casing 4. 3
It is arranged as shown in the figure. More specifically, the exhaust outlet 10 and the intake air intake 6 are arranged side by side on one side of the main part, and the two intake air blow-off lowers are arranged side by side near the front of the top. The indoor air intake port 9 is arranged between the two air supply blow-off lowers near the rear of the top. Therefore, the route 8a from the air intake 6 of the first air passage 8 to the total heat exchanger 12 and the route 11a from the total heat exchanger 12 of the second air passage 11 to the exhaust outlet 10 are It is configured vertically in parallel to the rear and front sides on one side of the main body 1, and includes a path from the total heat exchanger 12 of the first air passage 8 to the two supply air blowing lowers, and a second air passage. The route from the indoor air intake port 9 of the passage 11 to the total heat exchanger 12 is the main body 1.
In the front, the front side and the back side are parallel to each other in the vertical direction. In the air supply intake 6 of the first air passage 8,
The outlet side of a supply air blower 16 that sucks outside air is connected to the duct 5. Further, the exhaust outlet 10 of the second air passage 11 is connected by a duct 5 to the suction side of an exhaust blower 17 that sucks indoor air and exhausts it to the outside. An exhaust duct 5a for local ventilation is connected to the duct 5 connecting the exhaust blower 17 and the exhaust outlet 10, and the suction end of the exhaust duct 5a is disposed in a place with an odor, such as a toilet. Furthermore, ducts 5 are connected to the two air supply blow-off lowers and the indoor air intake port 9, respectively, thereby configuring an air conditioning system including a housing structure as shown in FIG. 4.

The top of the main body 1 is covered with a removable duct cover 3 attached to the front. The pedestal 2 on which the main body 1 is mounted has a storage section in which a heat source device 18 is installed, and the heat source device 18 that heats the heat medium sent to the air-conditioning coil 13 is incorporated in this storage section.

The heat source device 18 is FF when configuring a heating-only system.
A hot water boiler 18a equipped with a type combustor may be used, but when configuring an air conditioning system, a cooling unit 18b is installed in addition to the hot water boiler 18a as the heat source device 18, and the hot water boiler 18a, cooling unit 18b, and air conditioning coil are installed. 13
will be connected to the piping. The heat source device 18 may be an outdoor unit of a heat pump. In addition, 19 in the figure
is a drain receiver disposed below the total heat exchanger 12;
is an air filter.

The floor-mounted air conditioner with the above configuration is installed on the floor in or near a room in a house where the air is easily contaminated, or, for example, on the installation plane of a sanitary room L1 with high air cleanliness as shown in FIG. By installing piping and heat medium piping, effective air conditioning of the entire house is possible, and with the exception of duct piping, there is no need for ceiling construction for installation, and equipment construction is simple. Furthermore, maintenance can be easily carried out and the system is user-friendly.

Cooling or heating is performed by operating the heat source device 18, the air conditioning coil 13, and the circulation blower 14. That is, by operating the circulation blower 14, a part of the first air passage 8 and the third air passage 15 are
An airflow is formed between the air conditioning and heating coils 13, and the airflow that becomes cooling air or heating air is blown out from each air supply blowing lower through the duct 5 into the room L2 of the house. Room L where cooled or heated air is supplied
A pressure gradient is created in which the pressure gradually decreases from room L2 toward the installation location of the floor-mounted air conditioner, and the air circulating around room L2 is sucked into the third air passage 15 from the circulating air intake port 21 opened at the front. Rarely, circulating in the house. For ventilation, the exhaust blower 17 and the supply air blower 16 are operated to exhaust a portion of the indoor air to the outside through the second air path 11, and the outdoor air is passed through the first air path 8 to the room L2. This is carried out by supplying L. This air supply/exhaust ventilation is performed through a total heat exchanger 12 built into the main body 1 so that state variables such as indoor temperature and humidity do not change due to ventilation. In addition, with the operation of the exhaust blower 17, the exhaust duct 5
A suction force is applied directly to the exhaust duct 5a, and a room such as a toilet in which the suction end of the exhaust duct 5a is disposed is exhausted without passing through the total heat exchanger 12. Therefore, odor components will not remain or accumulate in the main body 1 due to the passage of odor-laden air from a toilet or the like. The circulation blower 14 can operate two lines individually, and can also perform air conditioning operation only for the room L2 that requires air conditioning.

If the open end of the duct 5 connected to the indoor air intake port 9 is placed in a room where the air in the house is easily contaminated, such as the kitchen, this room will have a negative pressure, so efficient and energy-saving differential pressure ventilation can be performed. Moreover, if it is installed in a sanitary room L1 with high air purity as shown in FIG. 4, highly clean cooling air or heating air can be circulated and supplied to each room L2.

Structurally, the first air passage 8 and the third air passage 15 are the heating and cooling coil 1.
3 and can exchange heat with a large amount of air, which has the advantage that the heating and cooling coil 13 can be made smaller. In addition, since the circulation blower 14 is provided in two lines in parallel,
Not only is air conditioning possible for each system, but it is also easier to downsize the entire system by using a large blower. Furthermore, the third air passage 1
Since all the outlet ends and inlet ends of the ventilation systems other than 5 are arranged together at the top of the main body casing 4, the duct piping can be easily organized and the appearance is improved.

Fig. 5 shows an application example of a floor-mounted air conditioner, in which the air flow from the supply air blowing lower is introduced into the plenum chamber 22, a multi-system duct 5b is connected to this plenum chamber 22, and the second floor area is It is possible to configure the air conditioning system for the first floor or the air conditioning system for the first floor. In addition, in FIG. 5, 23 indicates a damper, and 24 indicates an air supply bypass.

[Effects of the Invention] As is clear from the explanations of the embodiments, according to the present invention, by simply installing the product on the floor in an appropriate place, such as in a room where the air is easily polluted or in the vicinity of the room, the effective It is possible to obtain an air conditioner that is easy to use, easy to perform air conditioning, easy to install, and easy to maintain. In particular, for example, a toilet containing an odor can be sucked in through an exhaust duct and exhausted directly to the outside using an exhaust blower, so that heat exchangers, filters, etc. do not have odors, making it suitable for indoor installation.
