Specifically, the air conditioning facility described in Patent Document 1 includes a skylight provided on the roof of a building so as to be opened and closed, and a ceiling fan provided below the skylight. Then, based on the outside air temperature and the room temperature, the skylight is switched between opening and closing and the operation and stopping of the ceiling fan.

JP 2006-349318 A

  In addition, since how to feel the air temperature varies greatly depending on each user (that is, even if the temperature is the same, some users feel cold and some feel warm), as described in Patent Document 1. Therefore, it is not an appropriate method to control the operation of the air conditioning equipment uniformly according to the temperature.

That is, it is preferable that the coldness and warmth felt by the user himself are appropriately reflected in the operating state of the air conditioning equipment.
However, even if the user feels cold, it is up to the user to actually start using the heating device, and the heating device may not be used even if it is cold. Similarly, even if the user feels warm, it is up to the user to actually stop using the heating device, and even if he / she feels warm, he / she can continue using the heating device as a habit. is there. Thus, for example, the user himself / herself is often not aware of the time when the use of the heating device should start or the time when the use of the heating device should be stopped. For this reason, appropriate temperature control using a heating device is not performed, and it is also conceivable that the user sometimes harms health due to cold.

  The present invention has been made in view of the above-described problems, and its purpose is to appropriately obtain the user's reaction to cold or warmth, and to recommend the operation of the heating device to the user. It is in the point which provides the heating recommended state determination system which can perform the suitable proposal of whether it is.

In order to achieve the above object, the characteristic configuration of the recommended heating state determination system according to the present invention includes a heat supply device that generates heat, and
Hot water or water generated using the heat supplied from the heat supply device is used for bath bathing, showering, and general use that directly contacts a user other than those uses. A hot and cold water use device that uses the hot water or water in a state left to the user's choice;
A heat utilization state detection unit for detecting a utilization state of heat supplied from the heat supply device in the hot water utilization device;
Referring to the detection result of the heat utilization state detection unit, analyze the utilization state of the heat supplied from the heat supply device in the general application within the past predetermined period, and based on the analysis result, A recommended heating season determination unit that determines whether or not it is a recommended season for operation of the heating device;
It is in the point provided with the information presentation part which presents a judgment result by the above-mentioned heating recommendation time season judgment part to a user.

  According to the above characteristic configuration, the hot-water or water-using device is used for hot water or water in a bath or hot water application, a shower application, and a general application that directly contacts a user other than those applications. It is made to use in the state which left to the user's selection which is used. That is, if the user feels cold, the user should use hot water for general purposes, and if the user feels warm, the user should use water for general purposes. Therefore, it can be said that the general application in which hot water or water is in direct contact with the user is an application in which the user himself / herself expresses whether or not it is a cold season for the user.

  Then, the recommended heating season determination unit refers to the detection result of the heat utilization state detection unit that detects the heat utilization state in the hot water utilization device, and the heat supply in the general application within the past predetermined period. The use state of the heat supplied from the apparatus is analyzed, and based on the analysis result, it is determined whether or not it is a time to recommend the operation of the heating apparatus. In other words, if the state where the use of heat for general purposes is equal to or greater than the set amount is continuous over time, it can be said that the situation that the user feels cold is continuous over time. On the other hand, if the state where the use of heat in a general purpose is less than the set amount is continued in time, it can be said that the situation that the user feels warm is continued in time. As a result, the recommended heating season determination unit refers to the detection result of the heat utilization state detection unit that reflects the transition of whether the user feels cold or warm within a predetermined period in the past. It is possible to accurately determine whether or not it is time to recommend the operation of the heating device to the user. And the information presentation part presents the determination result by the recommended heating season determination unit to the user, so that it is possible to make an appropriate proposal as to whether or not it is the time to recommend the operation of the heating device to the user. it can.

  Another characteristic configuration of the recommended heating condition determination system according to the present invention is that the recommended heating season determination unit has a past state in which the use of heat supplied from the heat supply device is less than a set amount in the general application. After a certain period of time, when the use of the heat supplied from the heat supply device in the general application exceeds the set amount, it is determined that it is a time to recommend the operation of the heating device. .

After the state where the heat usage for general use is less than the set amount has continued for a certain period in the past, the situation where the heat use for general use exceeds the set amount is that the user felt warm. It can be determined that a situation has occurred where the user feels cold after a certain period of time in the past.
Therefore, in this feature configuration, the recommended season determination unit for heating is used when the use of heat for general use exceeds the set amount after a period of less than the set amount continues for a certain period of time in the past. Based on the assumption that a state that the user feels cold has occurred, it is determined that it is time to recommend the operation of the heating device. As a result, the information presentation unit can make a suggestion that it is time to recommend the operation of the heating device to the user.

Still another characteristic configuration of the recommended heating state determination system according to the present invention includes a water temperature detection unit that detects a temperature of water supplied to the hot water utilization device,
The heating recommended season determination unit satisfies a water temperature condition that the temperature of the water detected by the water temperature detection unit is lower than a set water temperature, and the heat supplied from the heat supply device in the general application. After the state where the usage is less than the set amount continues for a certain period in the past, when the use of the heat supplied from the heat supply device in the general application exceeds the set amount, the operation of the heating device is recommended. It is in the point to judge that it is time to do.

In a warm climate, the temperature of the water supplied to the hot water utilization device is relatively high, and in a cold climate, the temperature of the water supplied to the hot water utilization device is relatively low. That is, the approximate season can be objectively determined based on the temperature of the water supplied to the hot water utilization apparatus. For example, if the temperature of the water supplied to the hot water utilization apparatus is equal to or higher than the set water temperature, that is, if it is an objectively warm season, even if the user uses heat for general purposes, heating is performed. It is inappropriate to recommend the operation of the device.
Therefore, in this feature configuration, the water temperature detection unit detects the temperature of the water supplied to the hot water utilization device, and the heating recommended season determination unit determines that the water temperature detected by the water temperature detection unit is less than the set water temperature. After the condition is satisfied (that is, it is an objectively cold season) and the heat usage for general use is less than the set amount for a certain period in the past, the heat for general use is When the use of becomes more than the set amount, it is determined that it is the time to recommend the operation of the heating device. That is, it is possible to make a proposal that it is a time when it is recommended that the user should operate the heating device only for a season that is objectively cold.

Still another characteristic configuration of the heating recommended state determination system according to the present invention includes a reservation receiving unit that receives an operation reservation of the heating device,
Even if the information presenting unit determines that it is time to recommend the operation of the heating device by the recommended heating season determination unit when the reservation receiving unit receives an operation reservation of the heating device, the determination The result is that the result is not presented to the user.

Even if it is determined that it is the time to recommend the operation of the heating device by the recommended heating season determination unit, if the user intends to operate the heating device, the determination result is information that is not important for the user. .
Therefore, in this feature configuration, since the user's intention to operate the heating device is clearly shown by the operation reservation of the heating device, it is determined that it is the season when the recommended heating season determination unit recommends the operation of the heating device. Even if it is done, the judgment result is not proposed to the user.

  Still another characteristic configuration of the recommended heating condition determination system according to the present invention is that, when the information presentation unit is in a season that is not suitable for preset operation of the heating device, the recommended heating period determination unit performs the heating. Even if it is determined that it is time to recommend the operation of the apparatus, the determination result is not presented to the user.

  According to the above characteristic configuration, it is possible to avoid the occurrence of an event such as recommending the operation of the heating device in a warm season such as summer.

  Still another characteristic configuration of the recommended heating condition determination system according to the present invention is that the recommended heating season determination unit is in the past that the use of heat supplied from the heat supply device in the general application is more than a set amount. When the use of the heat supplied from the heat supply device in the general application becomes less than the set amount after a certain period of time, it is determined that it is a season when the operation of the heating device is not recommended. is there.

The situation where the user's use of heat for general purposes has become less than the set amount after the state where the use of heat for general purposes exceeds the set amount for a certain period of time has been felt that the user felt cold. It can be determined that a situation has occurred where the user feels warm after a certain period of time in the past.
Therefore, in this feature configuration, the recommended season determination unit for heating is used when the heat usage in the general purpose becomes less than the set amount after the state in which the heat usage in the general purpose exceeds the set amount for a certain period in the past. It is determined that it is a season when the operation of the heating device is not recommended based on the assumption that a situation that the user feels warm has occurred. As a result, the information presentation unit can make a suggestion to the user that it is a season when the operation of the heating device is not recommended.

  Still another characteristic configuration of the recommended heating state determination system according to the present invention is that the heat use state detection unit is configured to use a preset heat use pattern in the bath-watering application and heat use in the shower application. Referring to the situation pattern, from the utilization data of all the heat in the hot water utilization device, data that is estimated to be the utilization of heat in the general application is extracted, and the extracted data is extracted by the user by the user When it is determined that the heat is used for general purposes, the extracted data is determined to be based on the heat used for general purposes.

  According to the above characteristic configuration, the detection of the use of heat for general use by the heat use state detection unit becomes accurate through approval by the user. As a result, the accuracy of the determination result as to whether or not it is the time to recommend the operation of the heating device, which is performed by the recommended heating season determination unit based on the detection result of the heat utilization state detection unit, is increased.

It is a figure which shows the structure of a heating recommended state determination system. It is a graph which shows the example of the utilization condition pattern of hot water. It is a figure which shows the operating method of the heating recommended state determination system. It is a graph which shows the example of the utilization condition pattern of hot water in the past four days.

  FIG. 2 is a graph showing an example of a daily hot water usage pattern (instantaneous value and average value per hour). As shown in the figure, in the hot water usage pattern, the hot water usage pattern in the bath hot water application 5c, the hot water usage pattern in the shower application 5b, and a user other than those uses The usage pattern of hot water in general use 5a in which hot water or water is in direct contact is included. Examples of the general use 5a include use of hot water at the time of washing and use of hot water at the time of washing of tableware and the like.

  The storage unit 7 stores information for distinguishing a hot water usage pattern in the bath hot water application 5c, a hot water usage pattern in the shower usage 5b, and a hot water usage pattern in the general usage 5a. ing. In the example shown in FIG. 2, as the instantaneous value, the amount of heat of about 35,000 kcal / h in the bath hot water application 5c, the amount of heat of about 25,000 kcal / h in the shower application 5b, and about 5000 kcal / h or less in the general application 5a, respectively. Distributed. In such a case, if the amount of heat measured by the hot water supply thermal load measuring means 31 serving as the heat utilization state detection unit is, for example, 30000 kcal / h or more, the recommended heating season determination unit 1a is used for hot water filling in the hot water bathing application 5c. If it is determined to be a usage pattern and if it is 15000 kcal / h or more and less than 30000 kcal / h, it is determined that it is a usage pattern of hot water in shower application 5b, and if it is less than 15000 kcal / h, it is determined The usage pattern is configured to be determined.

  Alternatively, the recommended heating season determination unit 1a can perform selection based on the flow rate (L / min) of hot water instead of the amount of heat. For example, it is often used at a flow rate of about 15 L / min in the bath hot water application 5c, at a flow rate of about 10 L / min in the shower application 5b, and at a flow rate of about 5 L / min or less in the general application 5a. Therefore, if thresholds commensurate with these flow rates are set, the recommended heating season determination unit 1a detects the hot water detected by the hot water supply thermal load measuring means 31 (in this case, a flow meter) as a heat utilization state detection unit. With the flow rate (L / min), it is possible to determine the hot water usage pattern in the bath hot water application 5c, the hot water usage pattern in the shower usage 5b, and the hot water usage pattern in the general usage 5a. .

  Alternatively, the recommended heating season determination unit 1a uses the information about the average value shown in FIG. 2 to use the hot water usage pattern in the bath hot water application 5c and the hot water usage pattern in the shower usage 5b. And you may perform the discrimination | determination of the utilization pattern of the hot water in the general use 5a similarly.

  In the bath hot water application 5c and the shower application 5b, it is considered that hot water is used every time regardless of the season or temperature. On the other hand, in the general use 5a, hot water seems to be used in winter or cold days, but water may be used in summer or warm days. In other words, the general use 5a, which is the use of hot water at the time of washing and the use of hot water at the time of washing dishes, etc., is in direct contact with the user and uses the hot water or uses water. Since the decision is left to the user, it may be said that the user unintentionally expresses whether or not it is a cold season for the user.

  As described above, when attention is paid to the hot water usage pattern in the general purpose 5a, it is possible to know whether or not it is a cold season for the user. Then, the heating recommended state determination system of this embodiment pays attention to the hot water usage pattern in the general application 5a and determines whether or not the use of the heating device 6 is recommended.

FIG. 3 is a diagram illustrating an operation method of the heating recommended state determination system.
For example, in the recommended heating state determination system, the process of the flowchart shown in FIG. 3 is executed at a predetermined timing such as 0:00.
In the process # 10, the recommended heating season determination unit 1a refers to the detection result of the hot water supply thermal load measuring unit 31 as the heat utilization state detection unit, and the heat supply device for the general use 5a within the past predetermined period. The utilization state of the heat supplied from 21 is analyzed.

  FIG. 4 is a graph showing a heat utilization state in the hot water utilization apparatus 5 within the past four days at the time of 0:00. Specifically, FIG. 4 shows an example in which a warm day lasts for 3 days from 4 days ago to 2 days ago, but the temperature drops one day ago. As a result, as shown in FIG. 4, the hot water is not used for the general purpose 5a for 3 days from 4 days to 2 days ago, but the hot water is used for the general purpose 5a one day before. Yes. In other words, the user felt warm for 3 days from 4 days ago to 2 days ago, but can be regarded as felt cold 1 day ago.

  In step # 20, the recommended heating season determination unit 1a determines whether it is a recommended season for the operation of the heating device 6 based on the analysis result. Specifically, in the recommended heating season determination unit 1a, the state of use of heat supplied from the heat supply device 21 in the general purpose 5a being less than a set amount (for example, 10 kcal / h, etc.) continues for a certain period in the past. After that, when the use of the heat supplied from the heat supply device 21 in the general application 5a exceeds the set amount, it is determined that it is a time to recommend the operation of the heating device 6. On the other hand, the heating recommended season determination unit 1a, after the state in which the use of heat supplied from the heat supply device 21 in the general purpose 5a is less than the set amount continues for a certain period in the past, further, the general purpose 5a When the use of the heat supplied from the heat supply device 21 is less than the set amount (that is, when the warm state continues for the user), it is determined that it is not the time to recommend the operation of the heating device 6. .

  FIG. 5 is a graph showing a heat utilization state in the hot water utilization apparatus 5 within the past four days at time 0:00. Specifically, FIG. 5 shows an example in which cold days continued for 3 days from 4 days ago to 2 days ago, but the temperature rose one day ago. As a result, as shown in FIG. 5, the hot water is used for the general purpose 5a for 3 days from 4 days to 2 days ago, but the hot water is used for the general purpose 5a one day before. Absent. That is, it can be considered that the user feels warm.

In this case, in step # 20, the recommended heating season determination unit 1a determines that the use of heat supplied from the heat supply device 21 in the general application 5a is equal to or more than a set amount based on the analysis result in the past certain period. After four consecutive days (in this example), when the use of heat supplied from the heat supply device 21 in the general purpose 5a becomes less than the set amount, it is determined that it is a season when the operation of the heating device 6 is not recommended. To do. In other words, the user felt that it was cold for three days from four days ago to two days ago, but it can be considered that the user felt warm one day ago.
In addition, in this example, although the heating recommended season determination part 1a demonstrated the example based on the analysis result of the utilization condition of the heat in the hot water utilization apparatus 5 for the past 4 days, the past 3 days, the past 5 days, etc. The length of the period can be changed as appropriate.

  In step # 30, the information presentation unit 13a presents the determination result by the recommended heating season determination unit 1a to the user. When a specific example is given, when it is determined that the recommended heating season determination unit 1a is in the recommended season for the operation of the heating device 6, letters and voices such as “How about using the heating device because it is cold?” Can be output by the information presentation unit 13a. On the other hand, when the recommended heating season determination unit 1a determines that it is a season when the operation of the heating device 6 is not recommended, letters and sounds such as "Why should I stop using the heating device because it has become warmer?" Can be output by the information presentation unit 13a.

  As described above, the recommended heating season determination unit 1a reflects the transition of whether the user feels cold or warm within a predetermined period in the past, and the hot water supply heat load measurement as the heat utilization state detection unit is reflected. With reference to the detection result of the means 31, it is possible to accurately determine whether or not it is a season when the user is recommended to operate the heating device 6. And the information presentation part 13a presents the determination result by the heating recommendation time period determination part 1a to the user, so that an appropriate proposal as to whether or not it is the time to recommend the operation of the heating device 6 to the user. It can be carried out.

<Another embodiment>
<1>
In the said embodiment, although the specific example was given and demonstrated about the structure of the heating recommendation state determination system, those structures can be changed suitably.
For example, in the above embodiment, the case where the heat supply device 21 is configured to include the combined heat and power supply device 3, the hot water storage tank 4, and the like has been described. However, the heat supply device 21 does not include the hot water storage tank 4, and a fuel such as gas. It may be configured by a device that supplies heat generated by burning the gas.

Then, from all the heat utilization status data in the hot water utilization device 5, data that is assumed to be heat utilization in the general purpose 5a is specified, and the data is used by the user in the general purpose 5a. When the data is approved, it may be determined that the data is based on the use of heat in the general use 5a.

  For example, when the use of hot water having a calorific value of less than 15000 kcal / h is detected by the hot water supply thermal load measuring means 31 serving as a heat utilization state detection unit, the recommended season determination unit 1a for heating is used for the general purpose 5a. The information is temporarily determined to be a pattern, and the information presenting unit 13a outputs and presents "Have you used hot water other than bath and shower?" And when the input reception part 13b receives the reply which approves, such as "Yes" from a user, the heating recommended season determination part 1a determines that the utilization of the hot water is based on utilization of the heat in the general purpose 5a. And stored in the storage unit 7. As a result, the detection of the use of heat in the general application 5a by the hot water supply thermal load measuring means 31 as the heat utilization status detection unit becomes accurate through approval by the user. And the accuracy of the determination result of whether or not it is the time to recommend the operation of the heating device 6, which is performed by the recommended heating season determination unit 1 a based on the detection result of the hot water supply thermal load measuring means 31 as the heat utilization state detection unit Becomes higher.
