Description

In one embodiment of the present invention, a first air outlet that blows out a cold or warm air flow generated in a heat exchanger and extending in a horizontal direction at the time of installation, and a wind direction that can be freely changed with respect to the air flow blown from the first air outlet. The present invention relates to an air conditioner including a second air outlet that blows out room temperature air, and a control circuit that blows out the room temperature air from the second air outlet at a wind speed larger than the wind speed of the cool air or warm air that blows out from the first air outlet.

A stream of cold air or warm air from the first air outlet is Ru blown out. The air flow blown out from the second outlet can collide with the cold or warm air flow and control the direction and movement of the cold or warm air flow. Cold or warm air can be sent to a desired place indoors. Thus, the indoor temperature environment can be efficiently adjusted. Here, since the wind speed of room temperature air is higher than the wind speed of cold air or warm air, when the air flow of room temperature air is blown out so as to affect the air flow of cold air or warm air, the air flow of cold air or warm air can be controlled. Cool air can be sent far away and warm air can stay on the floor. The higher the wind speed from the second air outlet is, the more effective the wind speed from the first air outlet is.

The said control circuit can blow off the said room temperature air from the said 2nd blower outlet toward the upper space of the said warm airflow at the time of heating operation. The airflow of room temperature air blown out from the second outlet can suppress the rising warm air from above. Warm air can be kept near the floor. Thus, the occupants can feel warm well. If the wind speed from the second air outlet is higher than the wind speed from the first air outlet, the room temperature air flows along the floor surface and the occupants cannot feel warm well.

The control circuit changes the wind speed of the room temperature air following the change in the wind speed when the wind speed of the warm air is changed during the heating operation, and maintains the wind speed of the room temperature air at a wind speed larger than the wind speed of the warm air. can do. Thus, even if the wind speed of the warm air changes, the warm air can be reliably kept near the floor surface. The occupant can adjust the wind speed of the warm air according to the change in the sensible temperature, and as a result, can feel warm well.

FIG. 1 schematically shows a configuration of an air conditioner 11 according to an embodiment of the present invention. The air conditioner 11 includes an indoor unit 12 and an outdoor unit 13. The indoor unit 12 is installed in an indoor space in a building, for example. In addition, the indoor unit 12 may be installed in an environmental space corresponding to the indoor space. The indoor unit 12 indoor heat exchanger 14 is incorporated. The compressor 15 to the outdoor unit 13, the outdoor heat exchanger 16, expansion valve 17 and the four-way valve 18 is incorporated. Indoor heat exchanger 14, a compressor 15, an outdoor heat exchanger 16, expansion valve 17 and the four-way valve 18 forms a refrigeration circuit 19.

When the heating operation is performed in the refrigeration circuit 19, the four-way valve 18 connects the second port 18b and the fourth port 18d to each other and connects the first port 18a and the third port 18c to each other. A high-temperature and high-pressure refrigerant is supplied from the compressor 15 to the indoor heat exchanger 14. The refrigerant flows through the indoor heat exchanger 14, the expansion valve 17, and the outdoor heat exchanger 16 in order. From the refrigerant in the indoor heat exchanger 14 releases heat to the surrounding air. Warm air is generated. Warm air is caused to flow into the indoor space by the action of the first blower fan 27. The refrigerant is decompressed to a low pressure by the expansion valve 17. The decompressed refrigerant absorbs heat from the surrounding air in the outdoor heat exchanger 16. Thereafter, the refrigerant returns to the compressor 15.

Screws 66 are used to attach the first side panel 64a and the second side panel 64b to the structure 28. The screw 66 passes through the first side panel 64a and the second side panel 64b and is screwed into the main housing 63a. When the screw 66 is screwed in, the axis of the screw 66 is orthogonal to the virtual plane 67. The virtual plane 67 faces the front of the structure 28. Here, the virtual plane 67 is parallel to the horizontal axis 51 and parallel to the wall surface of the room when the indoor unit 12 is installed, and is positioned on the front side of the first side panel 64a and the second side panel 64b. To do. The main housing 6 3a has a boss 68 of the screw. A screw hole is formed in the boss 68. The screw hole faces the virtual plane 67. A screw insertion piece 69 is attached to the first side panel 64a and the second side panel 64b. The screw insertion piece 69 is overlaid on one surface of the boss 68. The screw 66 passes through the screw insertion piece 69 and is screwed into the boss 68.

Next, the operation of the air conditioner 11 will be described. For example, when the cooling operation is set, the air conditioning establishment unit 102 outputs a control signal for establishing the operation of the cooling operation. The control signal is supplied to the compressor 15, the expansion valve 17, and the four-way valve 18. The four-way valve 18 connects the second port 18b and the third port 18c to each other and connects the first port 18a and the fourth port 18d to each other. The refrigerant circulates in the refrigeration circuit 19 according to the operation of the compressor 15. As a result, cold air is generated in the indoor heat exchanger 14. The temperature of the cold air is at least lower than the temperature of the room air. The operation of the compressor 15 is controlled according to the room temperature detected by the room temperature sensor 114. In addition, for example, when the presence sensor is detected over a predetermined period by the human sensor 115, the compressor 15 may be stopped.

The second blower fan control unit 108 of the fan unit control block 107 outputs a second drive signal that drives each centrifugal fan 73. The second drive signal is individually supplied to each second blower fan drive source 75. The centrifugal fan 73 rotates. In the fan unit 26, room air is sucked into the space inside the fan housing 49 from the second suction port 52. The temperature of room air is equal to room temperature. The sucked room air is blown out from the second outlet 56 of the fan unit 26. At this time, indoor air is maintained at room temperature in the fan unit 26. Not exposed to heat exchanger. The housing posture control unit 109 of the fan unit control block 107 outputs a third drive signal for driving the fan housing 49 around the horizontal axis 51. The third drive signal is supplied to the fan housing drive source 86 for each individual fan unit 26. For example, as shown in FIG. 12, the posture of the fan housing 49 can change from a horizontal posture to a front lowering. The fan housing 49 can guide the airflow 122 from the second air outlet 56 downward from the horizontal direction. The indoor airflow 122 (hereinafter referred to as “room temperature airflow 122”) blows downward from the second outlet 56.

Generally, the indoor unit 12 is installed at a relatively high position indoors. If airflow 1 21 of the cool air is guided in the horizontal direction, the cold air will continue to descend toward the higher position on the floor. Cold air gradually accumulates indoors. The temperature environment of the whole room is adjusted with cold air. At this time, the fan unit 26 can direct the air flow 122 of room temperature air directly to the occupant M. The fan unit 26 can function as a substitute for a so-called fan during cooling operation. Mixing of cold air can be prevented in the air flow 122 of room temperature air, and as a result, the occupant M can obtain a comfortable cool feeling without feeling too cold. The occupant M can obtain a cool feeling based on the heat of vaporization generated by the air flow 122 in addition to the cool feeling based on the temperature drop in the room.

For example, when the heating operation is set, the cooling / heating establishment unit 102 outputs a control signal for establishing the operation of the heating operation. The control signal is supplied to the compressor 15, the expansion valve 17, and the four-way valve 18. The four-way valve 18 connects the second port 18b and the fourth port 18d to each other and connects the first port 18a and the third port 18c to each other. The refrigerant circulates in the refrigeration circuit 19 according to the operation of the compressor 15. As a result, warm air is generated in the indoor heat exchanger 14. The temperature of the warm air is at least higher than the temperature of the room air. The operation of the compressor 15 is controlled according to the room temperature detected by the room temperature sensor 114. For example, the compressor 15 may be stopped when the presence sensor occupies the absence of the occupant for a predetermined period.
