Abstract

PURPOSE:To simplify an operating condition of a room temperature adjusting machine by a method wherein an accumulated operating time at a reference set temperature and another accumulated operating time at each of varied and set temperature are collected and recorded in reference to an output from a clock device, it is statistically processed every time when a predetermined time is passed in reference to the recorded data, and then the reference set temperature is rewritten. CONSTITUTION:A central controlling device 27 may collect an accumulated operation time at a reference set temperature with 10 minutes being applied as one unit and an accumulated operating time at each of varied set temperatures modified by a remote inputting device 29 every day for 14 days, a temperature indicating maximum value of histogram got from accumulated data at 0A.M. of the fifteenth day is set as a new reference set temperature and then a content of a memory device 25 is rewritten into this temperature value. In this case, data is weighted for processing a statistic operation and old data, i.e. data of previous time from a present time is less weighted. Due to this fact, the written reference set temperature becomes near value where the most comfortable room temperature can be realized in addition to the surrounding air temperature at that season, resulting in that the number of operations for correcting the reference set temperature is reduced and thus a simplicity in use of the device can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an environment control device that comprehensively controls a plurality of environment control devices.

(Prior Art) As is well known, in order to maintain desired indoor environmental conditions, it is necessary to install multiple environmental conditioning devices such as heat pump air conditioners, humidifiers, air purifiers, ventilation fans, and dehumidifiers indoors. be. From such a thing.

Conventionally, an environment control device has been considered in which all or part of the above-mentioned environment control devices are installed in an environment control room and these environment control devices are comprehensively controlled.

By the way, in such an environmental control device.

Operation control of room temperature regulators such as heat pump type air conditioners and heaters is 9.
This is usually done in the following way. Namely.

A standard set temperature is stored in a storage device provided in the control box, and the room temperature regulator is normally operated so that the room temperature is controlled based on the standard set temperature. If you want to change the room temperature to a temperature that is different from the temperature controlled based on the standard set temperature, you can operate the temperature change switch on the control box panel or operate the remote input device. The value read from the storage device is corrected, and the operation of the room temperature regulator is controlled based on the corrected value. Further, the temperature change switch and remote input device also have a function of rewriting the standard set temperature itself stored in the storage device to a new standard set temperature.

However, the environment control device configured as described above has the following problems. In other words, since the seasons are changing from moment to moment, the outside temperature is also changing from day to day, albeit slowly. for example.

There is a difference between the average outside temperature at the first opening and the average outside temperature at the fourth opening in that month. Although it also depends on the structure of the two rooms, the room temperature is easily affected by the outside temperature. on the other hand.

A temperature sensor installed indoors to control a room temperature regulator usually detects the temperature at the location where the temperature sensor is installed, but does not detect the average temperature of the entire room. Therefore, even if the temperature detected by the temperature sensor is equal to the reference set temperature, the average temperature of the entire room does not necessarily match the reference set temperature. Furthermore, the comfortable temperature is not necessarily constant throughout the year and changes depending on the season. For this reason,
In order to maintain a comfortable temperature indoors, it is necessary to frequently modify the reference set temperature read out from the storage device in response to changes in the outside temperature, etc., and this modified value is also used as the outside temperature for that day. There is also a need to re-revise it in response to changes.

Such corrections and re-corrections are carried out by operating switches or remote human power devices as described above, but there is a problem in that the number of times these operations are required is extremely large.

Therefore, in order to reduce the number of operations as much as possible.

It is conceivable that the contents of the storage device, that is, the standard set temperature itself, could be changed each time by operating a switch or remote input device to correspond to the season or time of year.

There is the inconvenience of having to decide each time whether or not the degree of change is acceptable.

(Problem to be solved by the invention) As mentioned above, in the conventional environment control device.

In particular, there was a problem in that the operation of the room temperature regulator was troublesome.

Therefore, an object of the present invention is to provide an environment control device that can greatly simplify the operation of a room temperature regulator and improve ease of use.

[Structure of the Invention] (Means for Solving the Problems) An environmental control device according to the present invention includes a storage device that stores a reference temperature setting for controlling a room temperature regulator, and a clock device;
a central control device that gives operation commands to each environmental control device; a remote input device that can instruct the central control device to change a set temperature; the central control device, the remote input device, and each of the environments. An input/output control device that communicates with the control equipment, and total operating time at the standard set temperature and cumulative operating time at each changed set temperature changed by the remote input device, based on the output of the clock device. and means for recording the recorded data and performing statistical processing every time a predetermined period of time elapses based on the recorded data to rewrite the reference set temperature.

Furthermore, the environment control device according to the present invention performs statistical processing by giving different weights to old data and new data.

(for production) As mentioned above, the outside temperature changes in response to seasonal changes.

Furthermore, room temperature is easily affected by outside temperature.

Furthermore, the temperature sensor provided indoors to control the room temperature regulator does not detect the average temperature in the room.

Moreover, comfortable room temperature changes depending on the season.

In the environment control device having the above configuration, the cumulative operating time at the reference set temperature and the cumulative operating time at each changed temperature setting stored in the storage device are totalized and recorded.

Based on this recorded data, statistical processing is performed every time a predetermined period of time passes and the standard set temperature is automatically rewritten.

Therefore, the rewritten standard set temperature becomes a value close to a value that can realize the most comfortable room temperature, taking into account the outside temperature and the like at that time. In this way, the rewritten standard set temperature becomes a value close to the value that can achieve the optimum room temperature at that time, so the number of operations to correct this standard set temperature is inevitably reduced, making it easier to use. can be improved.

Furthermore, when performing statistical processing, if the old data is given a small weight and the new data is given a large weight, the rewritten reference setting temperature will be close to the optimum value at the time immediately before the rewriting.

It is possible to prevent the room temperature from changing rapidly each time the standard set temperature is rewritten.

(Example) An embodiment will be described below with reference to one drawing.

FIG. 1 is a schematic diagram of an example in which an environment control device according to an embodiment of the present invention is installed indoors.

That is, in FIG. 9, 1 indicates a room, and 2 indicates a partition forming the room 1.

Inside the room 1, nine environment adjustment devices necessary for adjusting the environment in the room 1, that is, an indoor unit 4 of a heat pump air conditioner 3, a dehumidifier 5, a humidifier 6, and an air purifier 7 are distributed. There is also a ventilation fan 8 in the hole provided in the partition 2.
is installed.

The outdoor unit 9 of the heat pump air conditioner 3 is placed outside one room 1. The heat pump air conditioner 3 is configured to exchange heat with indoor air in the indoor unit 4 and blow it out as cold air during cooling operation, and to flow heated refrigerant through pipes (not shown) embedded in the floor during heating operation. ing.

Inside the indoor unit 4, heating/cooling switching signals, start/stop signals, and temperature control signals are sent from a control device main body 21 (described later) via a commercial frequency power line 10 and an outlet 11 installed in the building. A controller that receives the information and controls the indoor unit 4 and outdoor unit 9 is built in. Dehumidifier 5
The humidifier 6 has a built-in humidity sensor and automatically operates to maintain the set humidity.
0 and the control device body 2 via the outlet 12.13
1, it is configured to operate only during the period for which an operation command is given. Air purifier 7.

It has a built-in smoke sensor and operates automatically, and is configured to operate only during a period when an operation command is given from the control device main body 21 via the power line 10 and the outlet 14. The ventilation G8 also has a built-in gas sensor and automatically operates to keep the gas concentration below the set value.
It is configured to operate only during a period when an operation command is given from the control device main body 21 via the outlet 15. Note that a filter 16 is installed at the starting end of the power line 10 to prevent the above-mentioned signal superimposed on the power supply voltage from leaking outside the consumer.

The control device main body 21 is housed in a control box and placed at an appropriate position in the room 1, for example, in the center, and is specifically configured as shown in FIG. 2. That is, the output of the run/stop switch 22 provided on the panel surface of the control box.

An input/output device 24 that accepts the output of the temperature sensor and the output of various setting switches 23 and sends control signals to the above-mentioned environmental control devices via the power line 10, and stores operating patterns and reference temperature settings corresponding to the seasons. a storage device 25 that measures February 1st, a clock device 26 that measures February 1st, and a clock device 26 that measures when an operation command is given to the input/output device 24.
a central control device 27 that reads the contents of the storage device 25 corresponding to the current time measurement contents and controls the input/output device 24 so that each environment adjustment device is operated according to the operating pattern and standard set temperature indicated by the contents; Current date and time, indoor temperature,
A display device 28 that displays operating status, etc., and an input/output device 24
It is comprised of a rotary remote input device 29 that can provide optical signals to the central control device 27 through a rotary remote input device 29, such as a start/stop signal and a set temperature change signal.

The central control device 27 has the following functions in addition to the functions described above. In other words, the cumulative operating time at the standard set temperature, with 10 minutes as one unit.

The cumulative operating time at each changed setting temperature changed by the remote input device 29 is totaled every day for 14 days, and 15
The temperature indicating the maximum value of the histogram obtained from the aggregated data at midnight of the day is set as the new reference setting temperature, and the contents of the storage device 25 are rewritten to this temperature value.

In this case, data is weighted during statistical processing, and older data, that is, data that goes back from the current time, is given smaller weights.

Next, the operation of the environment control device configured as described above will be explained. For example, in winter, run/stop switch 2
2 or by operating the remote input device 29 to give a driving command to the input/output device 24, the central control device 27 reads out the winter driving pattern from the storage device 25 based on the output of the clock device. According to the contents, each environment adjustment device is started to operate via the input/output device 24.

In this case, the operation pattern read from the storage device 25 is, for example, heating operation based on the reference temperature setting, dehumidifier off, humidifier on, and air purifier on.

This is a pattern where the ventilation fan is turned on. therefore.

Heat pump air conditioner 3 starts heating operation.

The humidifier 6 starts turning on and off based on the sensor output, and the air purifier 7 turns on based on the sensor output.

The off-operation is started, and the ventilation fan 8 starts on-off operation based on the sensor output. In other words.

It is possible to automatically start operation of all the environmental adjustment equipment necessary for adjusting the indoor environment in winter.

A good indoor environment can be created. .

By the way, the heating operation by the heat pump air conditioner 3 is performed based on the standard set temperature stored in the storage device 25. Therefore, it is not always possible to obtain a comfortable room temperature, and there may be cases where a higher or lower room temperature is better than the current one, depending on the outside temperature or the like.

In such a case, the reference set temperature read out from the storage device 25 can be corrected by operating the remote input device 29.

The room temperature is controlled based on this corrected value. Such corrections can occur many times within a day. FIG. 3 is a histogram showing an example of changes in the set temperature made during one day and the cumulative operating time at the changed temperature. In this example, the operating time at the reference set temperature +1 degree is the longest. Although the set temperature can be changed freely in this way, the central controller 27 aggregates the daily data shown in FIG. Rewrite and change the standard set temperature itself. This operation will be explained below with reference to the flowchart shown in FIG.

First, when you start the system at fl, f2
The output of the clock device 26 is taken in at.

Subsequently, the operation mode is determined in f3. The driving mode is determined depending on the season, such as spring, summer, autumn, or winter. Next, in f4, a reference set temperature is determined. In this case, it's right after the start.

A reference set temperature stored in advance in the storage device 25 is used. Next, a driving command is given at f5. As a result, each environment adjustment device starts operating. As shown in f6, when the remote human power device 29 is operated during operation to change the set temperature, the heat pump air conditioner 3 controls the indoor temperature according to the changed temperature.

Are you operating at the standard set temperature in fl?

It is determined whether the system is operating at the changed temperature that is the corrected standard set temperature, and this is plotted on the summary table at f8. Then, after waiting for 10 minutes at f9, fl
At O, it is determined whether the current time is midnight.

If it is not midnight, return to fl and repeat the above operation again.

If it is midnight, the data for the previous day summarized in a summary table will be sent out. This data is recorded in fil. At this time, fil records only data for 14 consecutive days, and deletes data from 15 days ago. Then, in fl2, the data for 14 days is compiled into a histogram as shown in FIG. At this time, the data is weighted.

Old data that goes back a long time is given a smaller weight. From the tally table obtained in this manner, the temperature showing the maximum value on the tally table is determined as the standard set temperature in fl3, and the contents of the storage device 25 are rewritten. Thereafter, the standard set temperature is rewritten every 14 days based on data for 14 days, and the room temperature is controlled based on this rewritten standard set temperature.

Therefore, it is an environmental control device with the above configuration.

The cumulative operating time at the reference set temperature and the cumulative operating time at each changed temperature setting stored in the storage device 25 are recorded, and based on this recorded data, statistical processing is performed every time a predetermined period elapses to determine the reference set temperature. is automatically rewritten. Therefore, the rewritten standard set temperature becomes a value close to a value that can realize the most comfortable room temperature, taking into account the outside temperature and other factors at that time.

In this way, the rewritten standard set temperature becomes a value close to the value that can achieve the optimum room temperature at that time, so the number of operations to correct this standard set temperature is inevitably reduced, making it easier to use. can be directed.

Also, during statistical processing, old data is given a small weight and new data is given a large weight.
The rewritten reference set temperature is close to the optimum value at the time immediately before being rewritten, and it is possible to prevent the room temperature from changing rapidly each time the reference set temperature is rewritten.

Note that in the above embodiment, data is collected for 14 days, but the data is not limited to this number of days.

For example, data for three days may be aggregated, and the reference temperature setting may be rewritten based on this data.

[Effects of the Invention] In the environment control device according to the present invention configured as described above, the operation of the room temperature regulator in particular can be greatly facilitated.

In addition, sudden changes in room temperature can be prevented, further improving comfort.
