Description

  The present invention relates to an air conditioner that controls airflows blown from a plurality of air outlets.

  In a conventional air conditioner, air that has passed through a heat exchanger that is long in the left-right direction is blown by a cross flow fan, and the wind direction plate and the left-right wind direction plate are provided at the outlet in order to change the wind direction up, down, left and right. Is provided.

  The air is blown with the up-and-down wind direction plate facing down during heating operation, and the air is blown up with the up-and-down wind direction plate facing up during cooling operation. There is a temperature difference between the upper and lower parts of the room. Usually, since the indoor unit is installed at the upper part of the wall surface, the temperature detected on the indoor unit side is higher than the temperature near the lower part of the room where the user is located. Therefore, the air conditioner corrects the set temperature to be higher so that the temperature near the lower part of the room where the user is located becomes the temperature set by the user, and the temperature detected on the indoor unit side becomes the corrected set temperature. There was an air conditioner that performs air conditioning control (see Patent Document 1).

JP-A-6-109606

  Since the air conditioner of Patent Document 1 blows only air that has passed through the heat exchanger, there is no problem in correcting the set temperature using a fixed correction temperature. However, when considering an air conditioner that includes a plurality of air outlets and can blow indoor air that does not pass through the heat exchanger from at least one air outlet, does the air flow direction or air flow of room air that does not pass through the heat exchanger? No, the temperature near the lower part of the room where the user is located is different. For example, during cooling operation, air is blown in the horizontal direction so that cold air that has passed through the heat exchanger does not directly hit the user, and indoor air that does not pass through the heat exchanger is blown toward the user, thereby A feeling of cold wind can be given, and cold air can be stirred. Further, during heating operation, the warm air that has passed through the heat exchanger is blown toward the floor surface, and indoor air that does not pass through the heat exchanger (temperature lower than the warm air) is blown upward from the warm air flow, thereby allowing the user to There is an effect to keep warmth by keeping the warm air near the lower part of the room where there is. As described above, since the temperature in the vicinity of the lower part of the room where the user is located changes depending on whether or not the room air that does not pass through the heat exchanger is blown, appropriate air conditioning control cannot be performed at a fixed correction temperature as in Patent Document 1. The problem arises.

  The present invention has been made in view of the above, and performs air conditioning control by combining an air outlet that blows indoor air that has passed through a heat exchanger and an air outlet that blows indoor air that does not pass through a heat exchanger. In this case, the correction temperature is changed in accordance with the blowing state of the indoor air that does not pass through the heat exchanger to correct the set temperature set by the user so that the temperature in the lower part of the room where the user is located becomes the temperature set by the user. An object is to provide an air conditioner that can be controlled.

In order to achieve the above-described object, an air conditioner of the present invention includes a heat exchanger inside, a main fan that blows conditioned air that has passed through the heat exchanger, and heat on at least one of both sides of the main fan. A side fan that blows indoor air that does not pass through the exchanger, and room temperature detection means that detects a room temperature, and the room temperature detected by the room temperature detection means is a predetermined value set in advance by a user. The air conditioner controls the air conditioning so as to approach the set temperature after correction corrected by the correction temperature of the air conditioner, and the air conditioner differs depending on whether the side fan is operating or not. Ri and and selects the correction temperature that differs according to the difference or the air volume of the side fan and the outside air temperature and the set temperature.

  In the air conditioner of the present invention, for the heating operation at the same set temperature, the correction temperature when the side fan is operated is higher than the correction temperature when the side fan is not operated. It is characterized by being lowered.

  In the air conditioner of the present invention, for the cooling operation at the same set temperature, the correction temperature when the side fan is operated is higher than the correction temperature when the side fan is not operated. It is characterized by being raised.

According to the air conditioner of the present invention, it has a main fan that blows conditioned air that has passed through a heat exchanger, and a side fan that blows indoor air that does not pass through the heat exchanger on at least one of both sides of the main fan. by indoor unit, unlike in a case that is not as when driving a side fan, and to correct the set temperature correction temperature that differs depending on the air volume of the differences or side fan and the outside air temperature and the set temperature There is an effect that the temperature in the vicinity of the lower part of the room where the user is located can be kept different depending on whether or not the side fan is operated.

  In addition, when the set temperature is the same, the corrected temperature when the side fan is operating is higher during cooling and lower during heating than the corrected temperature when the side fan is stopped. Since the set temperature is corrected as described above, there is an energy saving effect.

A suction port (not shown) is formed in the upper part of the exterior panel 29. The central outlet 30 opens downward. Such a housing body 28 can be fixed to, for example, an indoor wall surface. In that case, the front end 30a of the center blower outlet 30 is arrange | positioned in the upper position compared with the rear end 30b. As a result, the central outlet 30 is formed in a front-up posture at a predetermined inclination angle α. With such an action of the inclination angle α, the airflow can be blown not only downward from the central blower outlet 30 toward the floor surface but also in parallel (horizontal direction) to the floor surface.

  The central air outlet 30 is provided with a pair of front and rear wind direction plates 31a and 31b as main wind direction changing means. The up-and-down wind direction plates 31a and 31b can rotate around the horizontal axes 32a and 32b, respectively. Depending on the rotation, the vertical airflow direction plates 31a and 31b can open and close the central outlet 30.

  In addition, a left fan unit 261 and a right fan unit 262 are individually disposed on both side surfaces of the housing body 28.

  The indoor unit and outdoor unit of the air conditioner according to the present embodiment are configured as shown in FIG. An indoor heat exchanger 264 and a main fan 265 are incorporated in the main body unit 263 of the indoor unit 20 described above. The main fan 265 is a cross flow fan, and generates an air flow by rotation. Room air is sucked into the main unit 263 by the action of the main fan 265. The sucked room air passes through the indoor heat exchanger 264 and exchanges heat with the refrigerant, thereby generating cold air or warm air. The cold or warm airflow after passing through the indoor heat exchanger 264 is blown out from the central outlet 30 of the main unit 263 to become a main fan airflow 301. Further, the flow rate of the airflow passing through the indoor heat exchanger 264 is adjusted by the rotational speed of the cross flow fan.

  As shown in FIG. 2, the refrigeration circuit 41 of the outdoor unit 40 includes a four-way valve 42, a compressor 43, an outdoor heat exchanger 44, an outdoor fan 44a, an expansion valve 45, a refrigerant pipe 50, and the like.

Thereby, the high-temperature and high-pressure refrigerant is supplied to the outdoor heat exchanger 44 from the discharge pipe 43 b of the compressor 43. The refrigerant flows through the outdoor heat exchanger 44, the expansion valve 45, and the indoor heat exchanger 264 in order. In the outdoor heat exchanger 44, the heat energy of the refrigerant is released to the outside air. The refrigerant is decompressed to a low pressure by the expansion valve 45 and absorbs heat from the surrounding air in the indoor heat exchanger 264. The cold air thus generated is blown out into the indoor space by the function of the main fan 265. The refrigerant that has absorbed heat by the indoor heat exchanger 264 is returned to the compressor 43 via the four-way valve 42.

Thereby, the high-temperature and high-pressure refrigerant is supplied from the discharge pipe 43 a of the compressor 43 to the indoor heat exchanger 264. The refrigerant flows through the indoor heat exchanger 264, the expansion valve 45, and the outdoor heat exchanger 44 in order. In the indoor heat exchanger 264, the heat energy of the refrigerant is released to the surrounding air, and warm air is generated. Warm air is blown into the indoor space by the action of the main fan 265. The refrigerant is decompressed to a low pressure by the expansion valve 45 and absorbs heat from the surrounding air in the outdoor heat exchanger 44. Thereafter, the refrigerant is returned to the compressor 43.

  Further, the left fan unit 261 and the right fan unit 262 of the air conditioner according to the present embodiment are provided independently of the main unit 263. The left fan unit 261 and the right fan unit 262 include a side fan 266 made of a centrifugal blower and a left outlet 341 and a right outlet 342 for blowing out airflow sent from the side fan 266, respectively.

Is possible. The air blown out from the central outlet 30 is a main fan airflow 301 composed of cold air or warm air passing through the indoor heat exchanger 264. The left side fan airflow 3411 and the right side fan airflow 3421 blown out from the left outlet 341 and the right outlet 342 are airflows in which the room air sucked from the side suction ports 37 is blown out as it is.

  Then, the control system of the air conditioner of a present Example is demonstrated using FIG. The air conditioner according to the present embodiment includes an indoor unit 20 and an outdoor unit 40 as shown in FIG.

  FIG. 4 is a perspective view of the air conditioner installed on the wall surface 70, showing the blowing direction of the main fan airflow and the side fan airflow during the cooling operation, and FIG. 5 is a perspective view of the air conditioner installed on the wall surface 70. It is a figure which shows the blowing direction of the main fan airflow and side fan airflow at the time of heating operation.

(Example of air flow during cooling operation)
During cooling operation, as shown in FIG. 4, the vertical air direction of the main fan airflow 301 is fixed horizontally upward, and the left and right airflow direction of the main fan airflow 301 is the center front. Also, the left side fan airflow 3411 blown out from the left outlet 341 and the right side fan airflow 3421 blown out from the right outlet 342 are directed to the lower part of the room where the user is located, the left fan unit 261 and the right fan unit 262. The left side fan airflow 3411 and the right side fan airflow 3421 are blown downward (dotted lines in FIG. 4). In this way, during the cooling operation, the main fan airflow 301 is fixed horizontally, so that the cool air can be spread over the entire room without directly applying the cold air to the person 72, and the left side fan airflow 3411 The right side fan air flow 3421 directs indoor air that is not cold to the lower part of the room where the user is located, so that the air flow is applied to the user, so that the user can obtain an appropriate cool feeling and the cold air that tends to accumulate near the floor surface is generated in the room. The whole can be stirred.

(Example of airflow during heating operation)
At the time of heating operation, as shown in FIG. 5, the vertical air direction of the main fan airflow 301 is blown downward to supply warm air to the floor surface 71, and the horizontal airflow direction of the main fan airflow 301 is set to the center front. It is said. Also, the left side fan airflow 3411 blown out from the left outlet 341 and the right side fan airflow 3421 blown out from the right outlet 342 are directed inward by 10 ° in the left-right direction with respect to the main fan airflow 301 here. And the left fan unit 261 and the right fan unit 262 are rotated about 45 ° downward from the horizontal direction so that the main fan airflow 301 that is warm air is suppressed from above. The right side fan airflow 3421 is blown downward and slightly above the main fan airflow 301 (the broken line portion in FIG. 5). As described above, during the heating operation, the main fan airflow 301 is blown out downward and the left side fan airflow 3411 and the right side fan airflow 3421 are directed inward by 10 ° in the left-right direction with respect to the main fan airflow 301. Since the air is blown out so as to be suppressed from above with air having a temperature lower than that of the fan airflow 301, it is possible to suppress the rise of the warm air and to keep the warm air in the lower part of the room where the person 72 is present and to warm the vicinity of the floor 71.

  Next, temperature correction of the air conditioner will be described.

  In the air conditioner, if the room temperature (Tr) of the living space where the person 72 is located and the detection temperature (Tb) of the room temperature sensor 26 match, the detection temperature (Tb) of the room temperature sensor 26 is set by the user. What is necessary is just to control air conditioning so that it may become temperature (Ts). However, in the air conditioner, as shown in FIG. 4 or 5, the room temperature sensor 26 has the same height as the installation position (about 2 m) of the indoor unit 20, and is near the floor surface 71 where the person 72 is present. The air temperature is controlled by correcting the set temperature using a predetermined correction temperature (Tc) conventionally, because the air temperature differs by 1 to 2 ° C. due to the difference in height. For example, when the set temperature (Ts) is 20 ° C. and the correction temperature (Tc) is 2 ° C. during the heating operation, the correction temperature (Tc) 2 ° C. is added to the set temperature (Ts) 20 ° C. Air conditioning control is performed so that Tb) becomes the corrected set temperature 22 ° C. Note that the corrected set temperature is only a temperature for controlling the air conditioning, and the set temperature (Ts) 20 ° C. set by the user does not change.

  A feature of the air conditioner according to the present embodiment is that a side fan that blows indoor air that does not allow the indoor heat exchanger 264 to pass through at least one of both sides of the main fan 265 that blows conditioned air that has passed through the indoor heat exchanger 264. 266 is provided, and the temperature of the lower part of the room where the person 72 is present can be efficiently controlled by adjusting the air flow by the side fan that does not pass through the indoor heat exchanger 264 according to the operation mode. Therefore, in the air conditioner of this embodiment, the temperature difference between the upper part and the lower part of the room when the side fan 266 is operating is different from that when the side fan 266 is operating. A correction temperature (Tc) was prepared.

  An example of the correction temperature of the air conditioner of the present embodiment is shown in FIG. In the cooling operation mode, the cold air blown out by the main fan 265 is blown out horizontally in the direction of the ceiling (toward the ceiling) as shown in FIG. When the side fan 266 is ON, the room air blown out by the side fan 266 is blown toward the lower part of the room where the person 72 is located as shown in FIG. Therefore, the correction temperature (Tc) is set to “1 ° C.” and the detected temperature (Tb) detected by the indoor unit is controlled to be a temperature obtained by adding the correction temperature (Tc) to the set temperature (Ts). To. When the side fan 266 is OFF, there is no feeling of cool air due to the air blowing, so it is necessary to cool that much compared to when the side fan is ON. Here, the correction temperature (Tc) is “0 ° C.”. In the heating operation mode, the warm air blown out by the main fan 265 blows out toward the floor 71 as shown in FIG. When the side fan 266 is ON, the room air blown out by the side fan 266 is blown out so as to suppress the warm air from the main fan 265 from above as shown in FIG. By keeping warm air in the lower part of the temperature, the correction temperature (Tc) is “0 ° C.”, that is, no correction is performed. When the side fan 266 is OFF, there is no effect of suppressing the rise of warm air, so warm air accumulates near the ceiling and the temperature (Tr) in the lower part of the room where the person 72 is located is less likely to warm, so the set temperature is increased. Therefore, the correction temperature (Tc) is set to “2 ° C.”. As a result, when the side fan 266 is ON, compared to when the side fan 266 is OFF, the cooling operation is controlled to be higher than the set temperature (Ts), and the heating operation is set to be lower than the set temperature (Ts). As a result, proper temperature control can always be performed, and energy saving operation can be achieved.

  FIG. 7 is a flowchart for explaining the operation of the air conditioner according to the embodiment of the present invention. Hereinafter, the operation of the present embodiment will be described with reference to the flowchart of FIG. When the air conditioner starts operation, the indoor unit controller 21 of the indoor unit 20 of the present embodiment determines whether the operation mode is the cooling operation mode or the heating operation mode (step S100).

  Here, in the cooling operation mode, the process proceeds to step S101, and it is determined whether or not the side fan 266 is operating (ON or OFF). When the side fan 266 is ON (ON in step S101), the indoor unit control unit 21 uses the correction temperature (Tc) table (see FIG. 6) stored in the storage unit 23 to turn on the side fan in the cooling operation mode. The correction temperature “1 ° C.” is used to add the correction temperature (Tc) of 1 ° C. to the set temperature (Ts) to correct the set temperature (step S102).

  Then, air conditioning control is performed so that the detected temperature (Tb) of the room temperature sensor 26 becomes the corrected temperature (step S107). Thereafter, if the operation is stopped, the operation is ended (Yes in Step S108). If the operation is not stopped (No in Step S108), the process returns to Step S100 and the above process is repeated.

  In step S101, when the side fan 266 is OFF (OFF in step S101), the indoor unit control unit 21 performs cooling from the correction temperature (Tc) table (see FIG. 6) stored in the storage unit 23. Since the correction temperature is “0 ° C.” when the side fan is OFF in the operation mode, the corrected temperature remains the set temperature (Ts) (step S103). Thereafter, the operations in step S107 and subsequent steps are performed.

  If it is the heating operation mode in step S101, the process proceeds to step S104 to determine whether the side fan 266 is operating (ON or OFF). When the side fan 266 is ON (ON in step S104), the indoor unit control unit 21 uses the correction temperature (Tc) table (see FIG. 6) stored in the storage unit 23 to turn on the side fan in the heating operation mode. Therefore, the corrected temperature remains the set temperature (Ts) (step S105). Thereafter, the operations in step S107 and subsequent steps are performed.

  In step S104, when the side fan 266 is OFF (OFF in step S104), the indoor unit control unit 21 performs heating from the correction temperature (Tc) table (see FIG. 6) stored in the storage unit 23. Using the correction temperature “2 ° C.” when the side fan is OFF in the operation mode, the correction temperature (Tc) of 2 ° C. is added to the setting temperature (Ts) to correct the setting temperature (step S106). Thereafter, the operations in step S107 and subsequent steps are performed.

  The correction of the temperature is to correct the set temperature (Ts) set by the user, but the detected temperature (Tb) of the room temperature sensor 26 may be corrected. In this case, it is the same even if air-conditioning control is performed so that the temperature after the subtraction becomes the set temperature by subtracting the correction temperature (Tc) from the detected temperature (Tb) detected by the room temperature sensor 26.

  As described above, according to the air conditioner of this embodiment, when the side fan 266 that does not pass the indoor heat exchanger 264 for efficiently air-conditioning control of the temperature in the lower part of the room where the person 72 is located is operated. An appropriate correction value can be selected when the motor is stopped. In the air conditioner of the present embodiment, in both the cooling operation mode and the heating operation mode, the set temperature that is corrected when the side fan 266 operates is higher than that when the side fan 266 is not operating. Then, it is energy-saving because it is corrected to a higher setting temperature and lower during heating. Furthermore, in the air conditioner of the present embodiment, the correction temperature is changed depending on the operation mode. However, the correction temperature example shown in FIG. 6 is an example, and the temperature difference between the outside air temperature and the set temperature, the air flow rate of the side fan. The correction temperature can be appropriately set according to the above.

  As described above, an air conditioner according to the present invention includes an air outlet that blows conditioned air that has passed a heat exchanger through an indoor unit of the air conditioner, and an air outlet that blows indoor air that does not pass the heat exchanger. It is useful for air conditioners that have multiple air outlets and can individually adjust the air volume and direction of the air flow blown from each air outlet, and correct the set temperature set by the user depending on the presence or absence of side fan operation By changing the correction value to be performed, an air conditioner capable of always performing appropriate temperature control can be realized.
