Air conditioners such as those shown in FIGS. 1 and 2 are known. What is shown in Fig. 1 is an air conditioner that takes in outdoor air and cools it. A compressor 1, a condenser 2, a cooler 3, a controller 4, a distributor 5, a blower 6, etc. are each housed in a housing. It is placed in 7.
Although not shown, a pressure reducer is also installed.
These form a general refrigeration circuit and are used for air conditioning. This air conditioner is of a type that takes in outdoor air and cools it, so in this case, the outdoor air has a high heat potential, so the amount of air blown is reduced, and the outdoor air flowing through the cooler 3 has a good heat exchange. In order to ensure the flow velocity to maintain the air flow rate, the cooler 3 is designed to have a small cross-sectional area perpendicular to the air flow and to increase the heat exchange length along the flow, that is, the thickness. Therefore, in this case, the cooler 3 is provided opposite the outdoor air intake port 8 .

On the other hand, the air conditioner shown in FIG. 2 is of a type that takes in indoor recirculated air and cools it, and has the same components as the one shown in FIG. Therefore, in FIG. 2, the same parts as in FIG. 1 are designated by the same reference numerals. In this case, since the heat potential of the indoor recirculated air is relatively low, the cooler 3 has a large cross-sectional area perpendicular to the air flow and a heat exchange length along the flow, that is, to increase the air flow. It is designed to be relatively thin.

Therefore, in this case, the cooler 3 is arranged obliquely within the housing 7. 9 is an indoor air intake port.

By the way, since the conventional air conditioners mentioned above are made specifically for that purpose, it is important to have an outside air cooling function that takes in outside air to cool the room when the outside air is relatively low temperature, such as during the middle of the year. However, there were also difficulties in applying this method to cases where a large amount of outside air is taken in for ventilation, and where the amount of indoor air returned is also relatively large.

The air conditioner of the present invention has an indoor air intake 9 and an outdoor air intake 8 provided at substantially opposing positions on two opposing faces of a housing 7, i.e., on the front and back.
The indoor air intake 9 and the outdoor air intake 8
The cooler 3 is disposed in the housing 7 so as to cross diagonally between the indoor air intake 9 and the outdoor air intake 8 as shown in the figure.
Each of the three types of dampers 11 is provided with an outdoor fresh air control damper 11 for opening and closing the intake 8. A filter 12 is attached to the outdoor side of the outdoor fresh air control damper 11. Furthermore, a flow path switching damper 13 is provided from the outdoor air intake 8 side toward the cooler 3 at a position that divides the cooler 3 in two. This flow path switching damper 13 is also constructed so as to be freely opened and closed.
The dampers 10, 11, and 13 are, for example, made up of an array of blades rotated by a shaft, and block or allow air flow depending on the direction of the blades. Therefore, the operating state of each damper 10, 11, and 13 is defined as "open" to allow air flow to pass, and "closed" to block air flow.

Next, the operation of the air conditioner of the present invention configured as described above will be explained. Note that the operation of the refrigeration circuit is the same as a known one, so a description thereof will be omitted.

First, when this air conditioner is used for cooling indoor recirculated air, the indoor recirculated air control damper 10 and flow path switching damper 13 are opened, and the outdoor fresh air control damper 11 is closed. In this way, the flow of air introduced into the case 7 of the air conditioner is indicated by the symbol R in the figure.
As shown by the solid line marked with A, the air passes through the damper 10 provided at the indoor air intake 9 and flows over the entire surface of the cooler 3. Therefore, it is possible to cool air with a relatively low thermal potential by increasing the amount of air blown. At this time, outdoor air is blocked by the damper 11 and is not taken in.

Next, when this air conditioner is used for cooling by taking in outdoor fresh air, contrary to the above, the indoor recirculation air control damper 10 and the flow path switching damper 13
, and open the outdoor fresh air control damper 11. In this way, the flow of air introduced into the housing 7 of the air conditioner passes through the damper 11 provided at the outdoor air intake port 8, as shown by the thick dotted lines with symbols F and A in the figure. It flows to one half of the cooler 3 partitioned by the flow path switching damper 13, and then changes direction and flows to the other half of the cooler 3. Therefore, when looking at the cooler 3 along the air flow, the flow path area of the cooler 3 is approximately half that of the case where indoor recirculation air is cooled, and the heat exchange length is twice as large. Therefore, it is suitable for cooling air with a high thermal potential by reducing the amount of air blown. Note that in this case, indoor air is blocked by the damper 10 and is not taken in.

Further, when the air conditioner is used for outdoor air cooling, the indoor recirculation air control damper 10 is closed, and the outdoor fresh air control damper 11 and the flow path switching damper 13 are opened. In this way, the outdoor fresh air taken in through the damper 11 provided at the outdoor air intake port 8 is exclusively blown into the room, and the refrigeration circuit is operated when the outside temperature is low, such as in the middle of the season or at night. without any
It becomes possible to cool the room by so-called outside air cooling.

As described above, according to the present invention, there is provided an air conditioner that can be used both to cool air with a relatively low thermal potential and, conversely, to cool air with a high thermal potential, by controlling the opening and closing of the damper. Therefore, by sharing all the main components of the air conditioner, it becomes possible to cool air with a wide range of thermal potentials, and a compact and economically advantageous air conditioner can be obtained. In addition, when the outside temperature is low, outside air cooling is possible, and in this case, the refrigeration circuit is not operated, which has the effect of contributing to energy savings.
