TECHNICAL FIELD OF THE INVENTION
The present invention relates to an air conditioning system in which an air conditioner and a circulator for circulating indoor air are provided in the same room.
[0002]
[Prior art]
2. Description of the Related Art In general, a wall-mounted air conditioner installed on a wall or the like at the upper part of a room and air-conditioned indoors, and a ceiling-mounted air conditioner installed behind a ceiling and air-conditioned indoors are known. This type of air conditioner has a built-in heat exchanger and a fan, and after exchanging heat with the heat exchanger in the room sucked from the suction port, blows out the room from the outlet to air-condition the room. is there.
[0003]
By the way, since the air conditioner is installed in the upper part of the room, if the wind power of the fan is small during the heating operation, the warm air blown out from the air conditioner may not reach the feet and the feet may not be warmed. In addition, during cooling operation, there is a problem that cool air blown out from the air conditioner accumulates near the floor surface and the feet are too cold.
[0004]
For this reason, for example, as shown in FIG. 5, the conventional air-conditioning system includes an air conditioner 74 having a heat exchanger 71, a fan 72, and a temperature detecting unit 73 above a room R <b> 1, and a fan 75 and a temperature detecting unit. And a temperature detector 79 having a temperature detector 78 below the room R1. When the air conditioner 74 is operated for heating or cooling, the blower 77 is operated based on the detected temperature difference between the respective temperature detectors 73, 76, and 78, thereby circulating the indoor air and causing the indoor temperature difference. To reduce air conditioning and provide comfortable air conditioning. (For example, refer to Patent Document 1).
[0005]
Further, as another conventional air conditioning system, for example, as shown in FIG. 6, a cooling device 92 having a built-in fan 91 in the upper part of the room R2, and temperature detecting devices 93 and 94 in the upper part and the middle part of the room R2 are provided. When the floor-mounted heater 95 is disposed below the room R2 and the operation is performed, the fan 91 in the cooler 92 is blown when the temperature detectors 93 and 94 detect a predetermined value or more. Thus, the warm air in the upper part of the room R2 is guided to the lower part of the room R2 to circulate the air in the room R2, thereby reducing the temperature difference in the room and improving the heating effect. (For example, see Patent Document 2).

[0017]
In FIG. 2, the remote controller 3 includes a second room temperature sensor 31 for detecting a room temperature near the remote controller 3 (normally, a temperature in the lower part of the room), an operation switch 32 for operating and stopping the air conditioner 1, and cooling and heating. An operation unit 36 such as a cooling / heating changeover switch 33 for switching, a temperature setting switch 34 for setting a temperature setting, and a circulator switch 35; a display unit 37 for displaying a set temperature, cooling / heating, and the like; A transmission unit 38 for transmitting the temperature signal of the sensor 31 and the like are provided. The circulator switch 35 can switch between a combined operation in which the circulator 2 is operated in conjunction with the air conditioner 1 and a single operation in which the circulator 2 is operated alone. The air conditioner 1 controls the cooling and heating operation based on the difference between the value detected by the second room temperature sensor 31 and the set temperature.
[0018]
3 and 4, the circulator 2 has a vertically long box-shaped casing 41. A suction port 42 is provided on a lower surface of the casing 41, a blowout port 43 is provided on an upper surface, and a door 44 and an operation lamp 45 are provided on a front face. An air filter 46 for receiving dust and dust in the room R is provided at the opening 42, and a wind direction adjuster 47 is provided at the outlet 43. An air passage 48 is formed in the casing 41 to communicate the suction port 42 and the air outlet 43, and two air blow fans each using a propeller fan or the like are provided near the air inlet 42 and the air outlet 43 in the air flow path 48. 51a and 51b are provided, and when the blower fans 51a and 51b are driven to rotate, the air below the room R is sucked in and blown out upward to circulate the air in the room R. The operation, stop, and rotation speed of these blower fans 51a and 51b are controlled by the control device 17 (see FIG. 1) of the indoor unit 4.
[0019]
An air purifying box (hereinafter referred to as an air purifying box) 52 is provided between the blower fans 51a and 51b, and an air purifying unit 53 is housed in the empty purifying box 52 via a door 44 so as to be freely taken in and out.
[0020]
Next, an operation during a heating operation using the air conditioner 1 and the circulator 2 together will be described.
[0021]
When the circulator switch 35 of the remote controller 3 is set to the combined operation, the cooling / heating switching switch 33, the temperature setting switch 34 and the like are set and the operation switch 32 is turned on, the air conditioner 1 starts operating. The indoor fan 16 operates to suck indoor air from the suction port 11. The sucked air passes through the indoor heat exchanger 15 for heat exchange, and is blown out from the outlet 12 of the indoor unit 4. The control device 17 controls the operation of the air conditioner 1 based on the difference between the set temperature and the value detected by the second room temperature sensor 31.
[0022]
Here, for example, if the wind power of the indoor fan 16 is set to be weak, in the indoor R, the area around the indoor unit 4 is warmed, and the temperature near the ceiling becomes higher than near the floor. Then, the temperature is distributed so that the temperature gradually increases from the floor side to the ceiling side, and the temperature difference between the upper and lower parts of the room R increases.
[0023]
The controller 17 detects the room temperature with the first and second room temperature sensors 14 and 31 from the start of the operation of the air conditioner 1, and when these detected values have a temperature difference of 5 ° C. or more, for example. Operates the blowing fans 51a and 51b of the circulator 2 by a weak wind, and furthermore, when a temperature difference of 10 ° C. or more is generated, by a strong wind.
[0024]
When the circulator 2 starts operating, the air near the floor is sucked up and blown out toward the ceiling to generate a flow of air in the room R. The cool air near the floor is agitated with the warm air near the ceiling, and the temperature difference between the air in the room R becomes smaller and closer to uniform. Then, when the temperature difference becomes less than 2 ° C., the control device 17 stops the blower fan 51 and stands by.
[0025]
As described above, when the air conditioner 1 and the circulator 2 are used in combination to perform the heating operation, the cool air near the floor is sucked and the air in the room R is circulated. It can be resolved well.
[0026]
Next, the operation during the cooling operation using the air conditioner 1 and the circulator 2 together will be described.
[0027]
During the cooling operation, when the operation switch 32 of the remote controller 3 is turned on, cool air is blown from the outlet 12 of the indoor unit 4. Since the cool air tends to descend, for example, if the blowing air direction is set to be downward, the cool air accumulates near the floor surface and the temperature is distributed such that the temperature gradually decreases from the ceiling side to the floor side. Then, when the cooling operation continues, the temperature difference between the upper and lower portions of the room R increases.
[0028]
The control device 17 has detected the temperatures of the first room temperature sensor 14 and the second room temperature sensor 31 since the start of the operation of the air conditioner 1, and when the detected values of these temperature sensors 14 and 31 become equal to or higher than a predetermined temperature, the circulator. 2 starts operation. When the circulator 2 operates, cool air near the floor is sucked and blown out toward the ceiling, and the air in the room R circulates. The cool air near the floor and the warm air near the ceiling are agitated to reduce the temperature difference in the room R, and the temperature in the room R becomes substantially uniform.
[0029]
As described above, when the air conditioner 1 and the circulator 2 are used in combination for the cooling operation, the cool air near the floor is sucked and the air in the room R is circulated. It can be resolved well.
[0030]
As described above, the circulator 2 of the present air conditioning system is provided with the suction port 42 on the lower surface and the outlet 43 on the upper surface. Air circulation can be performed. In addition, since the blown wind does not directly hit the body, the occupants are prevented from feeling uncomfortable.
[0031]
In addition, since the circulator 2 is provided with the air filter 46 and the air cleaning means 53, dust and dust flying near the floor are removed by the air filter 46, and fine dust and odor passing through the air filter 46 are removed. The air in the room R can be effectively cleaned by removing the air with the air cleaning means 53.
[0032]
When the circulator 2 is operated independently of the air conditioner 1, the circulator 2 can be operated regardless of the room temperature sensor.
[0033]
As described above, the present invention has been described based on one embodiment, but the present invention is not limited to this, and can be variously modified without departing from the gist of the present invention.
[0034]
In the present embodiment, the description has been given using the wall-mounted air conditioner 1, but the air conditioner 1 may be a ceiling embedded type or a ceiling suspended type installed above the room R.
[0035]
Although the circulator 2 is not provided with the room temperature sensor in the present embodiment, for example, a third room temperature sensor is provided in the vicinity of the suction port 42 of the circulator 2, and based on a temperature difference between the third room temperature sensor and the first room temperature sensor 14. The circulator 2 may be operated in combination.
[0036]
Further, in the present embodiment, the air conditioner 1 and the circulator 2 are connected by wire using the signal line 7, but may be wirelessly connected so as to enable two-way communication.
[0037]
Although propeller fans are used as the blower fans 51a and 51b of the circulator 2, other types of fans such as a sirocco fan may be used.
[0038]
【The invention's effect】
As described above, according to the present invention, the operation of the circulator is performed based on the temperature difference detected by the first room temperature sensor provided in the indoor unit of the air conditioner and the second room temperature sensor provided in the remote controller. Since control is performed, the circulator can be operated at an appropriate timing.
[0039]
In addition, since the suction port is provided on the lower surface of the circulator and the air outlet is provided on the upper surface, it is possible to suck cold air that easily accumulates near the floor surface and blow it out of the room, thereby effectively circulating the air in the room.
[0040]
In addition, since the indoor air is circulated in the vertical direction, the cold air at the lower portion and the warm air at the upper portion intermingle with each other, so that temperature unevenness is reduced, and comfortable air conditioning can be performed.
