Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an air conditioner for configuring a cooling/heating device.

<Conventional Example and Problems> There is a heat pump type air conditioner for both cooling and heating that changes the flow of a heat medium to change the actions of an evaporator and a condenser.

This type not only complicates the piping that makes up the heat medium passage, but also requires a separate switching valve, which increases the number of parts, and requires installing a switching valve in the middle of the pipe for the heat medium passage. The number of connections increases, and heat medium leakage occurs frequently at these connections, resulting in increased costs and considerable effort for maintenance and management.

In addition, when dehumidifying, it is necessary to install a separate condenser or heating device for the evaporator installed inside the air conditioner and the condenser installed outside, and to install a switching valve to control these. .

<Means for Solving the Problems> The present invention was proposed in order to solve the above-mentioned drawbacks, and is capable of cooling, heating, dehumidifying, and dehumidifying in one air conditioner by operating a movable damper disposed inside. The purpose is to provide an air conditioning package that can be used in various combinations of the three.

The above purpose is to create a three-dimensional air conditioner in which one of the facing surfaces is an indoor surface and the other is an outdoor surface, where a part of the middle part between the indoor surface and the outdoor surface is divided into seven parts by a partition wall. a cooling chamber and a heating chamber; a cooler disposed in the cooling chamber; a heater disposed in the heating chamber; An inlet and an outlet are divided into seven parts by a partition, and a second inlet and an outlet are rotatably arranged independently to guide air from the inlet to the cooler and heater. first and second movable dampers, and third and fourth movable dampers that are independently rotatable in order to guide the air that has passed through the cooler and the heater to the air outlet; This is achieved by an air conditioner having a first fan disposed on the indoor surface and a second fan disposed on the outdoor surface.

<Example> Next, the present invention will be explained in more detail according to an example shown in the drawings.

In the figure, (1) is an outer frame body, which is formed into a cylindrical shape with a rectangular cross section and an open interior surface and an exterior exterior surface.

(2) is a partition wall that vertically divides a portion of the intermediate portion between the indoor surface and the outdoor surface of the outer frame (1) into seven parts.

In this embodiment, a cooler (3) is arranged on the upper side of the partition wall (2) to form a cooling chamber (4), and a heater (5) is arranged on the lower side to form a heating chamber (6).

As for the cooler (3), if a heat pump is used, an evaporator is used; if natural cooling is used, a heat exchange coil is used, and underground water or water for heat storage is allowed to flow inside. , Adopt a pad moistened with water.

In the case of the latter type of pad, it is preferable to provide a fan for forcibly blowing air onto it.

As the heater (5), if a heat pump is used, a condenser is used; if a natural heat source is used, a heat exchange coil is used to store hot spring water inside or discharge it from another location. It is also possible to allow the heat to pass through, or to drain ground water when the temperature of the ground water is higher than the air, such as in winter. In addition, it goes without saying that a heater, a heat radiation section of the engine, a heating furnace, etc. may also be provided.

II) It is a partition forming (+2).

Inlet (9) (10), cooler (3) and heater (
5), select either one of the inlets (9) and (10) to supply indoor or outdoor air to the cooler (3).
And movable dampers (13) (14) are provided for guiding the air through the heater (5).

Cooler (3) and heater (5) and air outlet (11) (
1, 2), the cooler (3) and the heater (5
) for selectively guiding the air passing through the air outlet (11) (I2) to either one of the air outlet (11) (I2).
6) is provided.

The above movable damper (13) (14) (15) (1
B) are provided so as to be able to rotate independently, and as will be described later, by operating these movable dampers (13) to (16), one air conditioner can perform heating, cooling, dehumidification, and all three functions. It is now possible to perform various combinations of.

(+7) (+8) are fans installed at the air outlet,
This fan operates to draw indoor/outdoor air into the intake port (9
) (1o) into the air conditioner, and the air outlet (11
) (12) to the outside of the air conditioner.

In addition, the fan (17) (+8) is connected to the air outlet (1, 1) (
12), that is, the center of the fan is the partition wall (2)
It is arranged so that it almost corresponds to the height of the

The suction ports (9) and (10) are provided with filters (1, 9) and (20) for removing dust.
) (32) are provided with end plates (21) and (22) for blocking the area around the fans (171, 13> and making the air passing through the air conditioner more efficient).

In the illustrated example, the movable dampers (13) to (16) are curved, but the present invention is not limited to this; straight plates may also be used.

(23) and (24) are pivot shafts for rotating the movable dampers (13) to (16), which may be provided separately for the cooling chamber (4) and the heating chamber (6), or may be arranged so that they communicate with each other. It may be placed in

Next, the operation of the air conditioner of the present invention will be explained based on FIG. 2.

In the figure, (W) is a wall that separates the indoor and outdoor areas of a greenhouse, for example, (wi) indicates the indoor space, and (W2) indicates the outdoor space.

Figure (a) shows a case where a room is heated.

On the cooling chamber (4) side above the partition wall (2), a movable damper (13H15) is closed on the indoor side so that only outdoor air passes through the cooler (3) and is discharged outside again.

Movable dampers (14) and (16) are set to close the outside of the heating chamber (6) on the lower side of the partition wall (as shown by the broken line) so that the indoor air circulates between the room and the air conditioner. has been done.

Therefore, indoor air enters the air conditioner through the suction port (9), passes through the heater (5), is warmed, and is discharged into the room again. On the other hand, on the cooling chamber (4) side, there is a movable damper (13)
(15) and the passage of indoor air is blocked, so it does not pass through the cooler (3) and is not cooled. Therefore, it is possible to heat only the indoor air for heating.

Figure (b) shows the case of cooling the room; contrary to the case of Figure (a) above, the indoor side of the cooling chamber (4) is opened and the heating chamber (6) is cooled.
The movable dampers (13) to (16) are set so as to close the sides.

In this case, the indoor air passes through the cooler (3), is cooled, and is again discharged into the room, thereby cooling the room. At this time, the indoor air passes through the movable damper (14) to the heater (5).
Since it is blocked by (16), it will not be heated.

Figure (C) shows the case where dehumidification is performed, and the movable damper (13) ~
(16) is set so that the indoor side is open and the outdoor side is closed.

Therefore, the indoor air passes through both the cooler (3) and the heater (5), and the cooled air and heated air are mixed and released into the room at the outlet. Although there is almost no change in temperature from when the air enters the conditioner, moisture is removed when the air is cooled by the cooler (3), so low-humidity air is released into the room.

Therefore, indoor dehumidification can be achieved. In this case, it is better to stop the fan (18).

Figure (d) shows a case in which heating is performed while taking in fresh air from outside.

In addition, various combinations can be used to convert outdoor air into coolers (
3) Since the air can be cooled or heated by passing through the heater (5), the indoor environment can be controlled as needed.

Furthermore, as shown in Fig. 3, at least the air outlet on the indoor side (
11) By disposing a swingable flow rate control plate (25) on the edge of the front partition wall (2), it is also possible to perform dehumidification in a slightly heating or cooling manner.

Note that the air conditioner of the present invention includes a cooler (3) as described above.
This is not limited to the case where the cooler (3) and the heater (5) are arranged above the partition wall (2), or when the partition wall (2) is arranged in a vertical direction. Of course, this also includes cases where

Effects> The present invention has the above configuration, and by controlling the movable damper, it is possible to switch between indoor cooling and heating, and
It is possible to dehumidify or bring in air from outside.

In addition, compared to those that change the flow of the heat medium, the piping for the heat medium can be simplified and the number of connections for the piping can be minimized, so problems caused by the connections can be avoided. In addition, since an expensive switching valve is not required, an air conditioner can be provided at a low cost.

In particular, in order to create an environment suitable for plant growth in a greenhouse for growing plants, a device that can perform various controls is required, and if the air conditioner of the present invention is adopted for this purpose, the configuration is simple and the operation is easy. This makes it easy to control the environment in terms of temperature, humidity, and ventilation.
