Description

Technical Field

[0001] The invention relates to the field of thermal comfort technology, and in particular to an indoor thermal comfort air conditioning control method based on elderly people with different frailty levels. Background Art

[0002] In recent years, the aging of society has prompted more and more scholars to focus their research on the indoor thermal comfort and environmental health of the elderly. At the same time, due to the frequent occurrence of extreme high temperatures in summer, the installation rate of air conditioners for the elderly is also increasing. However, due to the large differences in living habits, thermal comfort needs, physical health levels and adaptability between the elderly and young people, the elderly’s needs for indoor comfortable temperature are different from those of ordinary adults.

[0003] In many definitions, the elderly are defined as people over 60 or 65 years old. However, in daily life, it can be found that although the elderly are of similar age, their physical health conditions vary greatly. In the medical field, the different frailty states of the elderly are further divided into more precise "biological ages" to represent the comprehensive and complex changes in various organs in the body caused by aging. Elderly people with different levels of frailty have different health levels, and their ability to adjust to changes in external temperature is inconsistent. At the same time, the elderly are more sensitive to air conditioning. They are very afraid of the cold wind when using air conditioning and the long-term low temperature that causes them to have muscle soreness, joint pain and colds, and even trigger some potential diseases. These symptoms are more obvious in elderly people with poor health levels.

[0004] There are few air-conditioning control strategies designed for the elderly in existing technologies. The only aging-friendly air-conditioning control mode treats the elderly as a whole. Due to aging and various chronic diseases, the elderly's ability to control their body's temperature changes varies greatly.

[0005] Therefore, there is an urgent need to develop an air-conditioning control method based on the health level of the elderly to provide a more precise, comfortable and healthy intelligent control method for the indoor environment of the elderly. Summary of the invention

[0006] The purpose of the present invention is to provide an indoor thermal comfort air conditioning control method based on elderly people with different frailty levels to solve the problems existing in the prior art.

[0007] The technical solution adopted to achieve the purpose of the present invention is as follows: a method for controlling indoor thermal comfort air conditioning based on elderly people with different frailty levels, comprising the following steps:

[0008] 1) Fill in user information in the mobile terminal or remote control information input module. Obtain the user's elderly frailty level label according to the preset standard. Among them, the preset standard divides the elderly into three categories: non-frail stage, pre-frail stage and frail stage according to walking speed, weight, grip strength, activity level and self-assessed fatigue index.

[0009] 2) According to the frailty level label of the elderly, determine the preset exclusive control strategy corresponding to the user. The preset exclusive control strategy is designed according to the thermal sensitivity, thermal neutral temperature, thermal comfort temperature range and air conditioning usage habits of different frail elderly people.

[0010] 3) The air conditioner responds to the received control strategy instruction and performs corresponding actions.

[0011] Furthermore, in step 1), five indicators are used for classification: weight loss, self-assessment of weakness, poor endurance and physical fitness, slow movement, and low physical activity level. The presence of three or more of the above characteristics is classified as the frail stage. The presence of one or two of the above characteristics is classified as the pre-frail stage. The absence of the above five characteristics is classified as the non-frail stage.

[0012] Furthermore, in step 2), the neutral temperature and comfortable temperature range are derived from survey data of elderly people in areas with hot summers and cold winters. The thermal sensation voting data of the elderly people are recorded to calculate their thermal neutral temperature and thermal comfort temperature range.

[0013] Furthermore, thermal perception voting was evaluated using the ASHRAE seven-point thermal perception scale.

[0014] Furthermore, thermal sensitivity and neutral temperature can be obtained by linear regression of thermal sensation votes and operating temperature.

[0015] Furthermore, the functional relationship between the neutral temperature of the elderly with different frailty levels and their thermal sensation vote and operating temperature was calculated through linear regression, and the data were averaged using a weighted method with a step size of 0.5°C.

[0016] Furthermore, the regulation strategy for the elderly in the non-frail stage is marked as Regulation Strategy I. The regulation strategy for the elderly in the early stage of frailty is marked as Regulation Strategy II. The regulation strategy for the elderly in the frail stage is marked as Regulation Strategy III.

[0017] In control strategy I, when the air conditioner is started, the device is started according to the user's temperature setting and the time information is automatically detected:

[0018] If the time is between 9:00-23:00 and the temperature is set within the range of [26.0℃, 28.0℃], the indoor temperature is controlled according to the user's temperature preference. If the user sets the temperature within the range of [24.0℃, 26.0℃], the air conditioner automatically adjusts to the temperature range of [26.0℃, 28.0℃] after running in a relatively cool environment for 1 hour. If the indoor temperature is [26.0℃, 28.0℃] for a period of time, the user lowers the temperature again, and the return air temperature remains within the range of [24.0℃, 26.0℃]. If the user sets the temperature below 24.0℃, the air conditioner automatically adjusts to the working mechanism of [26.0℃, 28.0℃] to prevent the user from using the air conditioner incorrectly. If the user adjusts the temperature below 24.0℃ again after a period of time, it will operate according to the user's needs.

[0019] If the air conditioner is used during the time period of 23:00-9:00, and the detection time is between 23:00-3:00, most users are sleeping, and the temperature is set within the range of [28.0℃, 30.0℃] after the air conditioner is started. If the user adjusts the air conditioner to a lower temperature again at night, set it according to actual needs. After the time exceeds 3:00, the air conditioner automatically adjusts to an ultra-low wind speed or shutdown state. It will restart only if the indoor temperature exceeds 30℃. If it remains within the range of [28.0℃, 30.0℃], the air conditioner stops running. During the time period of 5:00-9:00, the air conditioner starts the fresh air mode. If the air conditioner is started during the time period of 5:00-9:00, the air conditioner is in cooling mode. If the temperature is set within the range of [28.0℃, 30.0℃], it runs at the set temperature. If the temperature is lower than 28℃, it will automatically adjust to the temperature range of [28.0℃, 30.0℃] after running for half an hour at the set temperature. If the user adjusts the air conditioner to a lower temperature again, set it according to actual needs. If it runs continuously from 5:00 to 9:00, the air conditioner starts the fresh air mode and stops the cooling mode.

[0020] In control strategy II, when the air conditioner is started, the device is started according to the temperature setting of the elderly, and the time information is automatically detected at the same time:

[0021] If the time is between 9:00-23:00 and the temperature is set in the range of [27.0℃, 28.0℃], the indoor temperature is controlled according to the user's temperature preference. If the user sets the temperature in the range of [24.5℃, 27.0℃], the air conditioner automatically adjusts to the temperature range of [27.0℃, 28.0℃] after running in a relatively cool environment for 1 hour. If the indoor temperature is [27.0℃, 28.0℃] for a period of time, the user lowers the temperature again, and the return air temperature remains in the range of [24.5℃, 27.0℃]. If the user sets the temperature below 24.5℃, the air conditioner automatically adjusts to the working mechanism of [27.0℃, 28.0℃]. To prevent users from using the air conditioner incorrectly, if the user adjusts the temperature below 24.0℃ again after a period of time, it will operate according to the user's needs.

[0022] If the air conditioner is used during the time period of 23:00-9:00, and the detection time is between 23:00-3:00, most users are sleeping, and the temperature is set within the range of [28.0℃, 29.5℃] after the air conditioner is started. If the user adjusts the air conditioner to a lower temperature again at night, it is set according to actual needs. After the time exceeds 3:00, the air conditioner automatically adjusts to an ultra-low wind speed or shutdown state. If the indoor temperature exceeds 29.5℃, it will restart. If it remains within the range of [28.0℃, 29.5℃], the air conditioner will stop running. During the time period of 5:00-9:00, the air conditioner starts the fresh air mode. If the air conditioner is started during the time period of 5:00-9:00, the air conditioner is in cooling mode. If the temperature is set within the range of [28.0℃, 29.5℃], it will run at the set temperature. If the temperature is lower than 28.0℃, it will run at the set temperature for half an hour and then [28.0℃, 30.0℃] If the user adjusts the air conditioner to a lower temperature again, it will be set according to actual needs. If it runs continuously from 5:00 to 9:00, the air conditioner starts the fresh air mode and stops the cooling mode.

[0023] In control strategy III, when the air conditioner is started, the device is started according to the temperature setting of the elderly, and the time information is automatically detected at the same time:

[0024] If the time is between 9:00-23:00 and the temperature is set in the range of [28.0℃, 29.5℃], the indoor temperature is controlled according to the temperature preference of the elderly. If the elderly set the temperature in the range of [26.5℃, 28.0℃], the air conditioner will automatically adjust the temperature to the range of [28.0℃, 29.5℃] after running in a relatively cool environment for 1 hour. If the indoor temperature is [26.5℃, 28.0℃] for a period of time, the elderly lower the temperature again, and the return air temperature remains in the range of [26.5℃, 28.0℃]. If the user sets the temperature below 26.5℃, the air conditioner automatically adjusts to the working mechanism of [28.0℃, 29.5℃]. In order to prevent the elderly from using the air conditioner incorrectly, if the elderly adjust the temperature below 26.5℃ again after a period of time, it will operate according to the needs of the elderly.

[0025] If the air conditioner is used during the time period of 23:00-9:00, and the detection time is between 23:00-3:00, most of the elderly are sleeping, and the temperature is set within the range of [29.0℃, 29.5℃] after the air conditioner is started. If the elderly adjust the air conditioner to a lower temperature again at night, set it according to actual needs. After the time exceeds 2:00, the air conditioner automatically adjusts to an ultra-low wind speed or shutdown state. If the indoor temperature exceeds 29.5℃, it will restart. If it remains within the range of [29.0℃, 29.5℃], the air conditioner will stop running. During the time period of 5:00-9:00, the air conditioner starts the fresh air mode. If the air conditioner is started during the time period of 5:00-9:00, the air conditioner is in cooling mode. If the temperature is set within the range of [28.0℃, 29.5℃], it will run at the set temperature. If the temperature is lower than 28℃, it will run at the set temperature for half an hour and then [28.0℃, 29.5℃] If the elderly adjust the air conditioner to a lower temperature again, set it according to actual needs. If it runs continuously from 5:00 to 9:00, the air conditioner starts the fresh air mode and stops the cooling mode.

[0026] Furthermore, the mobile terminal includes a mobile phone, a tablet computer, a smart watch, a smart speaker, a laptop computer, a smart TV, a smart panel or a smart screen.

[0027] The present invention also discloses an air conditioner remote controller, comprising a communication module, a control module and a storage module. The communication module is connected to the air conditioner and a mobile terminal for communication. The storage module stores an execution instruction. The execution instruction is configured to enable the air conditioner to execute any one of the indoor thermal comfort air conditioning control methods based on elderly people with different frailty levels when executed by the control module.

[0028] The present invention also discloses an air conditioner, comprising the air conditioner remote controller as described above, as well as a condenser, a fan and a fresh air system. The air conditioner responds to the control strategy instruction sent by the air conditioner remote controller, and the condenser, the fan and the fresh air system perform corresponding actions.

[0029] The technical effect of the present invention is unquestionable: a new control strategy is proposed based on the health level of the elderly (different levels of frailty), which is more conducive to the elderly with different needs in real life. The control strategy data comes from the survey data, which more objectively reflects the actual needs of the elderly with different levels of frailty. The survey data counts the neutral temperature and thermal comfort temperature range of the elderly with different levels of frailty, which is more meaningful in the field of thermal comfort. This survey data is the first time that the health level of the elderly and the actual thermal comfort needs are combined. At the same time, the survey also introduces the air conditioning control strategy according to the habits of the elderly using air conditioners during the day and at night and the introduction of fresh air, so that the air conditioning control can better meet the actual needs of the elderly. This is of practical significance to the elderly with different health levels. The control strategy allows the elderly to switch the air conditioner frequently at night, and the air conditioning switch program is automatically designed according to their habits, which is conducive to rest at night. The level of the elderly can be evaluated according to their actual information, so as to recommend a control scheme. The control strategy also takes into account the situation that the elderly are not good at using air conditioners. If they press the air conditioner by mistake, the default data is regulated according to the survey data. These default data come from the survey data of the real society to prevent them from using it incorrectly and causing the room to be too cold, making its regulation more suitable for the elderly.

Without departing from the above technical ideas of the present invention, various substitutions and changes are made according to the common technical knowledge and customary means in the art, which should all be included in the protection scope of the present invention.

[0038] Embodiment 1:

[0039] See also Figure 1 This embodiment provides an indoor thermal comfort air conditioning control method based on elderly people with different frailty levels, comprising the following steps:

[0040] 1) Fill in user information in the mobile terminal or remote control information input module. Obtain the user's elderly frailty level label according to the preset standard. Among them, the preset standard divides the elderly into three categories: non-frail stage, pre-frail stage and frail stage according to walking speed, weight, grip strength, activity level and self-assessed fatigue index.

[0041] 2) According to the frailty level label of the elderly, determine the preset exclusive control strategy corresponding to the user.

The presence of three or more of the above characteristics is classified as the frail stage. The presence of one or two of the above characteristics is classified as the pre-frail stage. The absence of the above five characteristics is classified as the non-frail stage.

[0045] Embodiment 3:

[0046] The main contents of this embodiment are the same as those of Embodiment 1 or 2, wherein, see Figure 3 , Figure 4 and Figure 5 In this embodiment, the control strategy for the elderly in the non-frail stage is marked as control strategy I. The control strategy for the elderly in the early stage of frailty is marked as control strategy II. The control strategy for the elderly in the frail stage is marked as control strategy III.

[0047] In control strategy I, when the air conditioner is started, the device is started according to the user's temperature setting and the time information is automatically detected:

[0048] If the time is between 9:00-23:00 and the temperature is set within the range of [26.0℃, 28.0℃], the indoor temperature is controlled according to the user's temperature preference. If the user sets the temperature within the range of [24.0℃, 26.0℃], the air conditioner automatically adjusts to the temperature range of [26.0℃, 28.0℃] after running in a relatively cool environment for 1 hour. If the indoor temperature is [26.0℃, 28.0℃] for a period of time, the user lowers the temperature again, and the return air temperature remains within the range of [24.0℃, 26.0℃]. If the user sets the temperature below 24.0℃, the air conditioner automatically adjusts to the working mechanism of [26.0℃, 28.0℃] to prevent the user from using the air conditioner incorrectly. If the user adjusts the temperature below 24.0℃ again after a period of time, it will operate according to the user's needs.

[0049] If the air conditioner is used during the time period of 23:00-9:00, and the detection time is between 23:00-3:00, most users are sleeping, and the temperature is set within the range of [28.0℃, 30.0℃] after the air conditioner is started. If the user adjusts the air conditioner to a lower temperature again at night, it is set according to actual needs. After the time exceeds 3:00, the air conditioner automatically adjusts to an ultra-low wind speed or shutdown state. It will restart only if the indoor temperature exceeds 30.0℃. If it remains within the range of [28.0℃, 30.0℃], the air conditioner stops running. During the time period of 5:00-9:00, the air conditioner starts the fresh air mode. If the air conditioner is started during the time period of 5:00-9:00, the air conditioner is in cooling mode. If the temperature is set within the range of [28.0℃, 30.0℃], it runs at the set temperature. If the temperature is lower than 28.0℃, it will automatically adjust to the temperature range of [28.0℃, 29.5℃] after running at the set temperature for half an hour. If the user adjusts the air conditioner to a lower temperature again, it will be set according to actual needs. If it runs continuously until the 5:00-9:00 time period, the air conditioner will start the fresh air mode and stop the cooling mode.

[0050] In control strategy II, when the air conditioner is started, the device is started according to the temperature setting of the elderly, and the time information is automatically detected at the same time:

[0051] If the time is between 9:00-23:00 and the temperature is set in the range of [27.0℃, 28.0℃], the indoor temperature is controlled according to the user's temperature preference. If the user sets the temperature in the range of [24.5℃, 27.0℃], the air conditioner automatically adjusts to the temperature range of [27.0℃, 28.0℃] after running in a relatively cool environment for 1 hour. If the indoor temperature is [27.0℃, 28.0℃] for a period of time, the user lowers the temperature again, and the return air temperature remains in the range of [24.5℃, 27.0℃]. If the user sets the temperature below 24.5℃, the air conditioner automatically adjusts to the working mechanism of [27.0℃, 28.0℃]. To prevent users from using the air conditioner incorrectly, if the user adjusts the temperature below 24.5℃ again after a period of time, it will operate according to the user's needs.

[0052] If the air conditioner is used during the time period of 23:00-9:00, and the detection time is between 23:00-3:00, most users are sleeping, and the temperature is set within the range of [28.0℃, 29.5℃] after the air conditioner is started. If the user adjusts the air conditioner to a lower temperature again at night, it is set according to actual needs. After the time exceeds 3:00, the air conditioner automatically adjusts to an ultra-low wind speed or shutdown state. If the indoor temperature exceeds 29.5℃, it will restart. If it remains within the range of [28.0℃, 29.5℃], the air conditioner will stop running. During the time period of 5:00-9:00, the air conditioner starts the fresh air mode. If the air conditioner is started during the time period of 5:00-9:00, the air conditioner is in cooling mode. If the temperature is set within the range of [28.0℃, 29.5℃], it will run at the set temperature. If the temperature is lower than 28.0℃, it will run at the set temperature for half an hour and then [28.0℃, 29.5℃] If the user adjusts the air conditioner to a lower temperature again, it will be set according to actual needs. If it runs continuously from 5:00 to 9:00, the air conditioner starts the fresh air mode and stops the cooling mode.

[0053] In control strategy III, when the air conditioner is started, the device is started according to the temperature setting of the elderly, and the time information is automatically detected at the same time:

[0054] If the time is between 9:00-23:00 and the temperature is set in the range of [28.0℃, 29.5℃], the indoor temperature is controlled according to the temperature preference of the elderly. If the elderly set the temperature in the range of [26.5℃, 28.0℃], the air conditioner will automatically adjust the temperature to the range of [28.0℃, 29.5℃] after running in a relatively cool environment for 1 hour. If the indoor temperature is [26.5℃, 28.0℃] for a period of time, the elderly lower the temperature again, and the return air temperature remains in the range of [26.5℃, 28.0℃]. If the user sets the temperature below 26.5℃, the air conditioner automatically adjusts to the working mechanism of [28.0℃, 29.5℃]. In order to prevent the elderly from using the air conditioner incorrectly, if the elderly adjust the temperature below 26.5℃ again after a period of time, it will operate according to the needs of the elderly.

[0055] If the air conditioner is used during the time period of 23:00-9:00, and the detection time is between 23:00-3:00, most of the elderly are sleeping, and the temperature is set within the range of [29.0℃, 29.5℃] after the air conditioner is started. If the elderly adjust the air conditioner to a lower temperature again at night, set it according to actual needs. After the time exceeds 2:00, the air conditioner automatically adjusts to an ultra-low wind speed or shutdown state. If the indoor temperature exceeds 29.5℃, it will restart. If it remains within the range of [29.0℃, 29.5℃], the air conditioner will stop running. During the time period of 5:00-9:00, the air conditioner starts the fresh air mode. If the air conditioner is started during the time period of 5:00-9:00, the air conditioner is in cooling mode. If the temperature is set within the range of [28.0℃, 29.5℃], it will run at the set temperature. If the temperature is lower than 28.0℃, it will run at the set temperature for half an hour and then [28.0℃, 29.5℃] If the elderly adjust the air conditioner to a lower temperature again, set it according to actual needs. If it runs continuously from 5:00 to 9:00, the air conditioner starts the fresh air mode and stops the cooling mode.

[0056] Embodiment 4:

[0057] The main content of this embodiment is the same as any one of embodiments 1 to 3, wherein this embodiment is based on a survey data, and the survey found that the elderly have different thermal neutral temperatures, thermal comfort temperature ranges and air conditioning use time at different levels of frailty. This embodiment is designed based on the survey data to control the indoor temperature of elderly people with different levels of frailty. This embodiment adopts Fried's frailty phenotype classification method, and divides the elderly into three categories: non-frail stage, pre-frail stage, and frail stage according to indicators such as walking speed, weight loss, grip strength, activity, and self-assessed fatigue. The neutral temperature and comfortable temperature range come from survey data on hot summer and cold winter areas. The survey included 394 elderly people, and their physical parameters were measured as a calculation to determine the level of frailty. At the same time, the indoor temperature was measured, and their thermal sensation voting data was recorded to calculate their thermal neutral temperature and thermal comfort temperature range. The thermal sensation voting uses the ASHRAE seven-point thermal sensation scale for evaluation (-3 cold, -2 cold, -1 slightly cold, 0 neutral, +1 slightly hot, +2 hot, +3 hot).

[0058] The frailty classification method adopted in the present invention is the frailty standard developed by Fried. Because it is simple and easy to use, it is often used for the primary assessment of the degree of frailty in the elderly. In the assessment, five indicators are mainly used for calculation, including: 1) weight loss; 2) self-assessment of frailty; 3) poor endurance and physical fitness; 4) slow movement; 5) low level of physical activity. The frail stage is defined as the presence of three or more of the above characteristics; the pre-frail stage is defined as the presence of one or two of the above characteristics; and the non-frail stage is defined as the absence of none of the above five characteristics. The survey counted the thermal sensation votes of 394 elderly people in their home environment and divided them into three different levels of frailty according to their physical parameters.

[0059] See also Figure 6 and Figure 7 In step 2), thermal sensitivity and neutral temperature can be obtained by linear regression of thermal sensation voting and operating temperature. Through linear regression, the functional relationship between the neutrality of elderly people with different degrees of frailty and their thermal sensation voting and operating temperature was calculated, and 0.5℃ was used as a step size, and the data were averaged using a weighted method. Figure 6It is a linear regression diagram of the average thermal sensation vote of the elderly with different degrees of frailty, and the calculation formulas are shown in formulas 1, 2, and 3. The results show that the neutral temperature of the elderly in the non-frail stage is 25.8℃, the neutral temperature of the elderly in the early stage of frailty is 26.9℃, and the neutral temperature of the elderly in the non-frail stage is 27.9℃. The slope of the average thermal sensation vote of the elderly in the non-frail stage is 0.1139, the slope of the average thermal sensation vote of the elderly in the early stage of frailty is 0.2001, and the slope of the average thermal sensation vote of the elderly in the frail stage is 0.3399. Therefore, the lower the slope, the lower the thermal sensitivity, especially the elderly in the frail stage are particularly sensitive to the low air-conditioning temperature in summer, so special attention should be paid to avoid the design of low air-conditioning temperature according to their needs.

[0060] The linear fitting equation of the average thermal sensation vote and operating temperature is as follows,

[0061] Non-frail elderly:

[0062] MTSV=0.11385*T OP -2.9297(R 2 =0.7010,P=0.00)

[0063] Elderly people in the early stage of frailty:

[0064] MTSV=0.20011*T OP -5.33714(R 2 =0.6134,P=0.00)

[0065] Frail elderly:

[0066] MTSV=0.33989*T OP -9.48766(R 2 =0.73244,P=0.00)

[0067] Where: MTSV is the mean thermal sensation vote, T op is the operating temperature.

[0068] According to the ASHRAE standard, the thermal comfort zone is defined as the temperature range in which at least 80% of users are satisfied with the thermal environment. In addition, due to the special needs of the elderly, ASHRAE recommends that the comfort zone for the elderly should be at least 90%. The present invention also uses 90% as the comfortable temperature range for the elderly. Through the regression model represented by formulas 1, 2, and 3, the comfortable temperature ranges for the elderly with three levels of frailty are determined as follows: 21.3°C to 30.1°C for non-frail elderly, 24.3°C to 29.3°C for pre-frail elderly, and 26.4°C to 29.3°C for frail elderly. According to the Chinese standard GB / T 50785, in China's hot summer and cold winter areas, when the thermal resistance of clothing is 0.5clo and TSV=-0.5, T min=24.0℃, T max =30.0℃. Therefore, for the elderly who are not in the frail stage, the lower limit of the temperature is set to 24.0℃ and the upper limit is set to 30.0℃. Figure 6 The thermal comfort zone is shown in Figure 2.

[0069] At the same time, the temperature setting of the air conditioner is generally 0.5℃ per gear. The rounding method is used to calculate the temperature range that can be recognized by the air conditioner controller. Therefore, the final comfortable temperature range for the elderly with different levels of frailty is: the comfortable temperature range for the elderly in the non-frail stage is [24.0℃, 30.0℃], the comfortable temperature range for the elderly in the early stage of frailty is [24.5℃, 29.5℃], and the comfortable temperature range for the elderly in the frail stage is [26.5℃, 29.5℃]. The neutral temperatures are: the neutral temperature for the elderly in the non-frail stage is 26.0℃, the neutral temperature for the elderly in the early stage of frailty is 27.0℃, and the neutral temperature for the elderly in the frail stage is 28.0℃.

[0070] In order to consider the energy saving of air conditioners, the preferred setting range of air conditioner temperature is in an environment where the thermal voting feeling is [0, 0.5] slightly hot and the temperature range that can meet the thermal comfort needs of the elderly is the temperature range from neutral temperature to the upper limit of the comfortable temperature range as the final setting temperature range of the air conditioner. That is, the air conditioner setting temperature range for the elderly in the non-frail stage is [26.0℃, 30.0℃], the air conditioner setting temperature range for the elderly in the early stage of frailty is [27.0℃, 29.5℃], and the air conditioner setting temperature range for the elderly in the frail stage is [28.0℃, 29.5℃].

[0071] At the same time, the survey also counted the time and frequency of air conditioning use by elderly people with different levels of frailty. Because non-frail elderly people prefer to go out during the day, the daytime air conditioning use rate in the statistics is lower than that of frail elderly people. Figure 7 As shown. At night, the air conditioning usage rate of the elderly in the non-frail stage is higher than that of the elderly in the frail stage. Statistics show that the elderly do not use air conditioning all day long according to their work and rest and living habits. In the hot summer, they have the habit of going out for a walk at dinner time or after dinner, and stop using air conditioning at home for a period of time. After 2:00-4:00 in the morning, some elderly people will have the habit of turning off air conditioning according to actual conditions. The elderly in the frail stage will greatly reduce the use of air conditioning at 2:00, and the elderly in the pre-frail and non-frail stages will reduce the use of air conditioning during the 2:00-4:00 period. The elderly do not want the air conditioning to be turned on all night, which is more obvious in the frail elderly. At the same time, in the early morning [5:00,9:00] period, most elderly people have the habit of opening windows for ventilation while using air conditioning, and they generally do not consider the high or low outdoor temperature. The early morning is the time period with the lowest temperature and the best air quality in the day, and they hope that the room can be ventilated to stay healthy.
