Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to control of an air conditioner, and more particularly, to control of the amount of air blown out of an air conditioner and the speed of air blown out of the air conditioner in relation to the formation of an indoor environment.

[0002]

2. Description of the Related Art In recent years, users' requirements for air conditioners have been
From something that simply warms or cools, to more comfortable,
It is changing to more energy saving. In addition, with the progress of energy saving in houses, the number of highly airtight and highly insulated houses is rapidly increasing, and the purpose of using air conditioners is to operate healthy and comfortable. Although this healthy and comfortable environment is closely related to human body temperature regulation, the current mainstream of home air conditioners is the wall-mounted forced convection type, and although there are many issues with the cooling environment in summer, There are many issues for the heating environment. This is largely due to the fact that the temperature of the blown airflow is high and the blown airflow rises, which is far from head cold foot heat, which has long been said, has a high temperature near the head, and a low temperature at the feet. In order to solve such problems, various airflow control methods have been developed. The ability to form an environment that differs depending on the air conditioner is called the ability to form an environment of the air conditioner.

FIG. 15 is a cross-sectional view of an experimental facility for evaluating the environment produced by an air conditioner. The outdoor environment is adjusted, the air conditioner is actually operated, and the indoor environment is centered on the illustrated temperature distribution in the room. Measurement can be evaluated. This experimental facility includes:
In particular, a ventilation device for adjusting the air-conditioning load is provided, and by adjusting the amount of ventilation, the air-conditioning load can be accurately controlled.

FIGS. 16 and 17 show the measurement results using this experimental facility. As an indoor environment evaluation index, there is a temperature difference between the vicinity of the head and the vicinity of the foot, which has a strong correlation with the thermal sensation of the human body. The average value of the vertical temperature difference is used. FIG. 16 shows the indoor environment characteristics when the heating load, which is the air conditioning load at the time of heating, is changed, and FIG. 17 shows the indoor environment characteristics when the blowing air volume is changed. It can be seen that when the amount of blown air is increased, the vertical temperature difference is reduced, and the indoor environment is improved.

[0005] Further, it can be seen that when the blowing air volume is the same, the vertical temperature difference becomes small when the air conditioning load is small, and the indoor environment becomes good. As described above, the blowing air volume has an influence on the environment forming power, and since there is a difference in the formed environment even when the blowing air volume is the same, it is understood that the environmental forming power also depends on the house. This means that a house having a large air conditioning load assumed at the time of designing the air conditioner has a large vertical temperature difference, and a house having a small air conditioning load has a large noise value due to an excessive blowing air volume. Therefore, in order to create a comfortable environment, it is necessary to have an air conditioner that has a wide range of environment-forming power that matches the environment-forming power of a house and controls the environment-forming power according to the usage environment.

Conventionally, in the case of a home air conditioner to which a refrigeration cycle is applied, one of the problems is to quickly raise the room temperature. Secondly, the amount of blown air is controlled from the viewpoint of reducing the amount of blown air as much as possible in relation to noise. That is, the control of the blown air amount is performed according to the temperature difference between the set temperature and the room temperature as shown in FIG. Considering the time of heating, when the difference between the room temperature and the set temperature is large, such as when starting up, the air volume is large, the coefficient of performance of the refrigeration cycle is good, and the heating capacity is large.
Rising fast. When the room temperature rises and approaches the set temperature,
The amount of blown air gradually decreases, and the temperature becomes the set room temperature and the noise decreases, resulting in a comfortable environment.

[0007] As an example of controlling the blow-off air speed which is related as an environment forming power, there is a cooling / heating machine disclosed in Japanese Patent Application Laid-Open No. 5-99490. FIG. 18 is a cross-sectional view showing the configuration of the air conditioner. In the drawing, reference numeral 17 denotes an outlet for blowing out cool air or warm air, and reference numeral 18 denotes an outlet provided in the outlet 17.
This is an outlet adjusting plate having a motor that changes the opening area of the outlet 17. Reference numerals 19 and 20 denote temperature detectors for detecting the upper and lower room temperature representatively. When the detected temperature difference between the upper room temperature detector 19 and the lower room temperature detector 20 exceeds a predetermined value, the temperature difference is detected. The degree of opening of the outlet adjustment plate 18 is controlled so that the blowing air speed increases in accordance with the degree of the air flow. The indoor environment is detected by two temperature sensors, and when the vertical temperature difference is large and the environment is poor, the outlet adjusting plate 18 is controlled to be slightly narrower to increase the blowing air speed and maintain a favorable environment.

[0008]

As described above, in the conventional air conditioner, the control is performed with a view to noise and energy saving, and no consideration is given to the environment forming power of the house or the air conditioner. In addition, there are air conditioners that try to control the environment forming power of the air conditioner by directly capturing the indoor environment.
It is necessary to detect near the equipment, and it is difficult to capture an appropriate and stable indoor environment due to cold air intrusion accompanying entry and exit.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and controls an air conditioner according to the environment forming power of a house so that the indoor environment does not change due to the performance of the house or the outside air temperature. The purpose is to create an air conditioner with a fast start-up that creates a comfortable environment and quickly obtains heating capacity.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. Hereinafter, a first embodiment of the present invention will be described with reference to FIG. In the figure, the same reference numerals as those of the conventional example indicate the same or corresponding parts as those of the conventional example. FIG. 1 shows a configuration of a first embodiment according to the present invention.
An air-conditioning load inference means 1 infers an air-conditioning load of a room currently being air-conditioned. The air-conditioning load inference means includes an air-conditioning load detecting unit 2 for detecting information necessary for inferring an air-conditioning load, and an information processing unit. It comprises an air conditioning load inference unit 3 for inferring an air conditioning load. Reference numeral 4 denotes an environment forming force control unit which receives the air conditioning load inferred by the air conditioning load inference unit 3 of the air conditioning load inference unit 1 and calculates and controls a necessary environment forming force, such as a difference in the vertical temperature of a room. The air conditioner includes an arithmetic unit 5 and an air conditioner 6 that controls the amount of air blown from the air conditioner based on the calculated environment forming power.

FIG. 2 is a block diagram showing an electric circuit according to the first embodiment. In the figure, 7 is a power switch, and 8 is a microcomputer unit of the air conditioner control device. The microcomputer unit 8 includes an input circuit 9, a CPU 10, a memory 11, and an output circuit 12. The input circuit 9 receives the blowout temperature 13, the suction temperature 14, and the blowout air volume of the air conditioner 6. The memory 7 stores signals from the air-conditioning load inferring unit 3 and the environment forming force calculating unit 5, calculates by the CPU 10, and outputs from the output circuit 12 to the air conditioner 6.

Next, the operation of the first embodiment will be described with reference to the flowchart shown in FIG. First, when the power is turned on by the user in step S101, the blowout air volume, the set temperature Sp, and the like are initialized in step S102. At step S103, the control waits for a control interval. When the control timing comes, a control flow other than this control is processed at step S104. This control interval is often several seconds to several tens of seconds. In step S105, the room temperature Tr
Is detected, and in step S106, the room temperature Tr is compared with the set temperature Sp, and the process proceeds to step S107 if the temperature difference is large, that is, if the temperature rises during heating. Step S
At 107, the amount of blown air is calculated.

As shown in FIG. 4, the blowout temperature is set by the difference between the set temperature and the room temperature. When the difference between the set temperature and the room temperature is large, the amount of blown air reaches the maximum value Hi, and when the room temperature rises and approaches the set temperature, the amount of blown air gradually decreases. When the room temperature Tr and the set temperature Sp decrease in step S106 and the difference between the room temperature Tr and the set temperature Sp becomes 1 deg or less, the process proceeds to step S108. In step S108, a duration time in which the difference between the room temperature Tr and the set temperature Sp is 1 deg or less is calculated. In step S109, the blowout temperature To of the air conditioner,
The intake air amount Ti and the blowout air amount Ga are detected and averaged. If the duration exceeds 5 min, the air-conditioning load is determined in step S111 by multiplying the product of the temperature difference between the blow-out temperature and the suction temperature and the blow-off air volume by the specific heat of air. Step S
At 112, the amount of blown air is calculated.

As shown in FIG. 5, the amount of blown air is set in accordance with the air-conditioning load ratio based on the maximum air-conditioning capacity. In other words, since the room temperature is stable, the air-conditioning load is almost equal to the air-conditioning capacity generated by the air conditioner. It becomes smaller when smaller. The amount of blown air is determined according to the air conditioning load when the air conditioner is stabilized as described above.

Step S112 or step S10
When the blowout air volume is determined in step 7, the duration is reset in step S113, and the indoor blower is controlled in step S114. If the duration is shorter than 5 minutes in step S110, the process returns to step S103, and the duration is integrated. Further, when a disturbance enters during the integration of the continuation time and the room temperature is largely separated from the set temperature, the calculation of the blown air amount is as shown in FIG. 4 in step S107, and the blown air amount is set based on the difference between the set temperature and the room temperature. Step S113
Resets the duration.

Next, the first embodiment will be described with reference to the characteristic diagram of FIG. The horizontal axis in FIG. 6 is a time axis,
This is an example of heating. When the user turns on the power of the air conditioner in a state where the set temperature is lower than the room temperature, the air conditioning capacity of the air conditioner becomes maximum and the room temperature rises rapidly.
Eventually, when the temperature reaches the vicinity of the set temperature, the compressor rotation speed of the air conditioner decreases, and the air conditioning capacity decreases. The control algorithm for the compressor rotation speed includes PID control, fuzzy control, and the like. Also, the amount of blown air starts to decrease.

In this control routine, the blowing air volume control shown in FIG. 3 is applied. When the set temperature and the room temperature become 1 deg or less at the time A shown in FIG. 6, the blowout temperature, the suction temperature and the blowout air amount are averaged, and when the continuation time becomes 5 min, the blowout air amount is selected in FIG. As shown in the figure, the air flow is controlled to the air flow according to the air conditioning load obtained from the air temperature, the air intake temperature and the air flow. The reason that the set temperature and the room temperature are 1 deg or less is when the room temperature is substantially stabilized, and the air conditioning capacity of the air conditioner at this time is substantially equal to the air conditioning load of the space to be air-conditioned by the air conditioner.

The average for a predetermined time is that the generation capacity of the air conditioner is constantly changing. When the instantaneous state is captured, control is performed when the air conditioning load and the air conditioning capacity are not equal, and a comfortable environment cannot be formed. , Indoor environment changes frequently,
This is because a stable and comfortable environment cannot be achieved. The predetermined time is about several minutes. In the case of the characteristic diagram shown in FIG. 6, the air conditioning capacity is normal at the time B, and there is no change in the blown air volume. At time B, the outside air temperature decreases and the air-conditioning load increases, and the air-conditioning capacity increases. The air-conditioning load is calculated from the averaged data from time B to time C. Is controlled. In this case, the blowing air volume increases. When the air conditioning capacity decreases from time D, time E
With this, the blowing air volume decreases. In this way, it is possible to obtain an environment in which the amount of air blown out is controlled in accordance with the air conditioning load, and which has a fast rise.

Embodiment 2 Next, Embodiment 2 is described with reference to FIG.
Will be explained. FIG. 7 is the same as FIG. 2 except that there is no input from the air conditioner 6 to the input circuit 9. The second embodiment is different from the first embodiment in that the air-conditioning load inferring means of the first embodiment is used to detect the air-conditioning load. The part is composed of an outlet temperature and an inlet temperature. As shown in FIG. 5, assuming that the blowout air amount is determined by the air conditioning load ratio, when the difference between the blowout temperature and the suction temperature is obtained, this value becomes a value that is successive to the air conditioning load, and the blowout air amount is determined according to this value. . By performing such control (not shown), the same operation as in the first embodiment is achieved, and the amount of air blown out is controlled according to the air-conditioning load, and a comfortable environment in which the indoor environment does not change due to the performance of the house or the outside air temperature is created. In addition, a rising environment can be obtained, and the same effect as in the first embodiment can be obtained.

Embodiment 3 FIG. Next, a third embodiment of the present invention will be described with reference to FIG. In FIG. 8, what is connected to the input circuit 9 is the suction temperature 14 and the temperature 15 of the indoor heat exchanger. According to the present invention, the air-conditioning load of the air-conditioning load inference means of the first and second embodiments is different. The outlet temperature of the detection unit uses the indoor heat exchanger temperature 15 detected by the refrigerant temperature detector installed in the indoor heat exchanger. The temperature efficiency of the indoor heat exchanger is high, the correlation between the outlet temperature and the indoor heat exchanger is high, and the temperature difference is small. An air-conditioning load or a value related to the air-conditioning load can be obtained from the indoor temperature and the data of the indoor heat exchanger, and the amount of blown air is determined according to this value (not shown). By controlling in this manner, the operation is the same as in the first and second embodiments, a comfortable environment in which the indoor environment does not change due to the performance of the house or the outside air temperature is created, and an environment in which the temperature rises quickly can be obtained. The same effects as those of the first and second embodiments are obtained.

In the drawing, what is connected to the input circuit 9 is the blow-out temperature 13 and the room temperature 16, and the fourth invention is based on the air-conditioning load detection unit of the air-conditioning load inference means of the first invention and the second invention. The suction temperature uses an indoor temperature detected by an indoor temperature detector installed indoors. If there is a sufficient amount of room ventilation air, the difference between the suction temperature and the room temperature is small, and the room temperature can be used as a substitute for the suction temperature. By using the indoor temperature instead of the suction temperature in this way, the same operation as the invention of the first embodiment and the invention of the second embodiment is achieved, and a comfortable environment in which the indoor environment does not change due to the performance of the house or the outside air temperature is improved. An environment that is creative and has a fast rise can be obtained, and the same effects as those of the invention of the first embodiment and the invention of the second embodiment can be obtained.

Embodiment 5 Next, a fifth embodiment of the present invention will be described with reference to FIG. In the figure, the air conditioner 6 is connected to the input circuit 9.
, The rotation speed of the compressor is input. Embodiment 5
Calculates the value based on the average air-conditioning load from the number of rotations of the compressor, and determines the amount of blown air according to this value in the air-conditioning load detecting unit of the air-conditioning load inference means of the first embodiment. The rotation speed of the compressor of the air conditioner (not shown) is controlled so that the room temperature becomes the set temperature, and has a value correlated with the air conditioning load.

As a result, the operation is the same as that of the first embodiment, and a comfortable environment in which the indoor environment does not change due to the performance of the house or the outside air temperature is created, and an environment with a fast start-up is obtained. The effect becomes.

Embodiment 6 FIG. Next, a sixth embodiment of the present invention will be described with reference to FIG. In FIG. 2, the air conditioner 6 includes an air conditioner 6 that determines the required air-conditioner blow-out area from the air-conditioning load determined by the environment forming force calculating unit 5 and controls the blow-out area of the air conditioner to the calculated blow-out area. In the sixth embodiment, a necessary environment forming force is calculated in accordance with this value from the air conditioning load inferred by the air conditioning load inferring means in the first embodiment, and a blowing area is determined in accordance with the environment forming force. It is. When the blowing area of the air conditioner (not shown) changes, that is, when the blowing area is constant, the blowing wind speed changes. There is a correlation between the blowing wind speed and the indoor environment, and by changing the blowing area, the same operation as in the first embodiment is obtained. When the air conditioning load is large, reduce the blowing area,
When the air conditioning load is small, the blowing area is controlled to be large.
As a result, the blowing area is controlled according to the air-conditioning load, and a comfortable environment in which the indoor environment does not change due to the performance of the house or the outside air temperature is created. Becomes

Embodiment 7 Next, a seventh embodiment according to the present invention will be described with reference to FIGS. FIG. 11 shows a configuration of a seventh embodiment according to the present invention.

At the control timing, a control flow other than this control is processed in step S204. This control interval is often several seconds to several tens of seconds. In step S205, the room temperature Tr is detected, and in step S206, the room temperature Tr is compared with the set temperature Sp. If the temperature difference is large, that is, if the room temperature rises, the process proceeds to step S207. In step S207, the amount of blown air is calculated.

As shown in FIG. 13, the airflow load is obtained by multiplying the product of the temperature difference between the blowout temperature and the suction temperature and the blown airflow by the specific heat of air in step S211 as shown in FIG.
In step 12, the amount of blown air is calculated. When setting the blowing air volume in step S212, correction is performed by a user input in step S213.

As shown in FIG. 14, the amount of blown air is set according to the air-conditioning load ratio based on the maximum air-conditioning capacity. That is, mode b is set, the mode is set to a large number with respect to the reference, and the mode c is set to a small number with respect to the reference. Here, when the user has made an input requesting the warmth of the feet, the mode a is more than the reference, and when the user has made an input requesting an environment with a lower noise value, the input is less than the reference. Control is performed so that the blown air amount set in the mode b is obtained. For this reason, it is possible to create a more comfortable environment that meets the needs of the user.

At this time, the air volume α is increased in the mode a and the air volume β is set small in the mode b. The values of the air volume α and the air volume β are set near the head and side portions shown in FIG. The average value of the upper and lower temperature differences, which is the temperature difference, is used as an index, and is set within a range in which the indoor environment with a small upper and lower temperature difference is good.
