Abstract

The application provides an indoor thermal comfort air conditioning regulation method based on the different frailty levels of the elderly. The regulation strategy is based on the frailty level of the elderly. The regulation strategy data is derived from the research data, which more objectively reflects the actual needs of the elderly with different frailty levels. The research data counts the neutral temperature and thermal comfort temperature range of the elderly with different frailty levels. The regulation strategy can let the elderly not frequently turn on and off the air conditioner at night, automatically design the air conditioner switching program according to their habits, and be beneficial to the rest at night. The level of the elderly can be evaluated according to the actual information of the elderly, so as to recommend the regulation scheme. The regulation strategy also considers the situation that the elderly are not good at using the air conditioner.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of thermal comfort, in particular to an indoor thermal comfort air conditioning control method based on different frailty levels of the elderly. BACKGROUND

[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 differences in life habits, thermal comfort needs, physical health levels and adaptability between the elderly and young people, the demand for indoor comfortable temperature of the elderly is different from that 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 ages of the elderly are similar, their physical health conditions differ greatly. In the medical field, the different frailty states of the elderly are further divided into more accurate "biological ages" to represent the comprehensive and complex changes in various bodies in the body caused by aging. The elderly with different frailty levels have different health levels, and their adjustment ability to external temperature changes is inconsistent. At the same time, the elderly are more sensitive to air conditioning, and they are very afraid of the cold wind feeling when using air conditioning and long-term low temperature, which makes them have muscle soreness, joint pain and cold, and even causes some potential diseases. These symptoms are more obvious in the elderly with poor health.

[0004] In the existing technology, there are few air conditioning control strategies designed for the elderly, and the only air conditioning control mode for the elderly regards the elderly as a whole. Due to the effects of aging and various chronic diseases, the body regulation ability of the elderly to external temperature changes is very different.

[0005] Therefore, it is urgent to develop an air conditioning control method based on the health level of the elderly to provide more accurate, comfortable and healthy intelligent control means for the indoor environment of the elderly. SUMMARY

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

[0007] The technical solution adopted to achieve the purpose of the present application is as follows: an indoor thermal comfort air conditioning control method based on different frailty levels of the elderly, comprising the following steps:

[0008] 1) Fill in the user information in the mobile terminal or remote control information input module. Obtain the old person frailty level label of the user according to the preset standard. Among them, the preset standard divides the old people into three categories of non-frail period, pre-frail period and frail period according to walking speed, body weight, grip strength, activity level and self-assessment fatigue index.

[0009] 2) According to the old person frailty level label, determine the preset exclusive control strategy corresponding to the user. Among them, the preset exclusive control strategy is designed according to the thermal sensitivity, neutral temperature, thermal comfort temperature range and air conditioner use habit of different frail old people.

[0010] 3) The air conditioner executes corresponding actions in response to the received control strategy instructions.

[0011] Further, in step 1), five indicators of weight loss, self-frailty assessment, poor endurance and physical ability, slow action and low physical activity level are used for division. The three or more characteristics are divided into the frail period. One or two characteristics are divided into the pre-frail period. The five characteristics do not exist and are divided into the non-frail period.

[0012] Further, in step 2), the neutral temperature and the comfort temperature range come from the survey data of the old people in hot summer and cold winter areas. The thermal sensation voting data of the old people are recorded to calculate their thermal neutral temperature and thermal comfort temperature range.

[0013] Further, the thermal sensation voting is evaluated by using the ASHRAE seven-point thermal sensation scale.

[0014] Further, the thermal sensitivity and the neutral temperature can be obtained by linear regression of the thermal sensation voting and the operating temperature.

[0015] Further, by linear regression, the functional relationship between the neutral temperature of the old people of different frailty degrees and their thermal sensation voting and operating temperature is calculated, and a step of 0.5℃ is used to average the data by using the weighted method.

[0016] Further, the control strategy for the non-frail old people is marked as control strategy I. The control strategy for the pre-frail old people is marked as control strategy II. The control strategy for the frail old people is marked as control strategy III.

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

[0018] If the time is between 9:00-23:00, the temperature is set in the range of [26.0℃, 28.0℃], the indoor temperature control is carried out according to the user's temperature preference. If the user's set temperature is in the range of [24.0℃, 26.0℃], the air conditioner runs in a cool environment for 1 hour, and then automatically adjusts to the temperature range of [26.0℃, 28.0℃]. If the user reduces the temperature again after experiencing the indoor temperature of [26.0℃, 28.0℃] for a period of time, the return air temperature is kept in 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 misusing the air conditioner. If the user adjusts the temperature below 24.0℃ again after a period of time, it is run according to the user's needs.

[0019] If the air conditioner is used in the time period of 23:00-9:00, the detection time is between 23:00-3:00, most users are in sleep time, the temperature is set in the range of [28.0℃, 30.0℃] after the air conditioner starts. If the user adjusts the air conditioner to a low temperature again at night, it is set according to the actual needs. After the time exceeds 3:00, the air conditioner is automatically adjusted to an ultra-low wind speed or a stop state. If the indoor temperature exceeds 30℃, it is restarted. If it is kept in the range of [28.0℃, 30.0℃], the air conditioner stops running. In the time period of 5:00-9:00, the air conditioner starts the new air mode. If the air conditioner is started in the time period of 5:00-9:00, it is in cooling mode. If the temperature is set in the range of [28.0℃, 30.0℃], it is run at the set temperature. If the temperature is lower than 28℃, it is automatically adjusted to the temperature range of [28.0℃, 30.0℃] after running at the set temperature for half an hour. If the user adjusts the air conditioner to a low temperature again, it is set according to the actual needs. If it is continuously run to the time period of 5:00-9:00, the air conditioner starts the new air mode and stops the cooling mode.

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

[0021] If the time is between 9:00-23:00, the temperature is set in the range of [27.0℃, 28.0℃], and the indoor temperature control is performed according to the user's temperature preference. If the user's set temperature is in the range of [24.5℃, 27.0℃], the air conditioner runs in a cool environment for 1 hour, and then automatically adjusts the temperature range of [27.0℃, 28.0℃]. If the user lowers the temperature again after experiencing the indoor temperature of [27.0℃, 28.0℃] for a period of time, the return air temperature is kept 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 the user from misusing the air conditioner, if the user adjusts the temperature below 24.0℃ again after a period of time, the air conditioner operates according to the user's needs.

[0022] If the air conditioner is used during the time period of 23:00-9:00, the detection time is between 23:00-3:00, and most users are in sleep time, the temperature is set in the range of [28.0℃, 29.5℃] after the air conditioner is started. If the user adjusts the air conditioner to a lower temperature at night, it is set according to the actual needs. After the time exceeds 3:00, the air conditioner automatically adjusts to an ultra-low wind speed or a stop state. If the indoor temperature exceeds 29.5℃ and restarts, if it remains in the range of [28.0℃, 29.5℃], the air conditioner stops running. During the time period of 5:00-9:00, the air conditioner starts the new air mode. If the air conditioner is started during the time period of 5:00-9:00, it is in cooling mode. If the temperature is set in the range of [28.0℃, 29.5℃], it runs at the set temperature. If the temperature is below 28.0℃, it runs 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 is set according to the actual needs. If it is continuously running during the time period of 5:00-9:00, the air conditioner starts the new air mode and stops the cooling mode.

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

[0024] If the time is between 9:00-23:00, the temperature is set in the range of [28.0℃, 29.5℃], and the indoor temperature control is performed according to the temperature preference of the old person. If the set temperature of the old person is in the range of [26.5℃, 28.0℃], the air conditioner runs in a cool environment for 1 hour, and then the temperature range of [28.0℃, 29.5℃] is automatically adjusted. If the indoor temperature of [26.5℃, 28.0℃] is experienced for a period of time, and the old person lowers the temperature again, the return air temperature is kept in the range of [26.5℃, 28.0℃]. If the user sets the temperature below 26.5℃, the air conditioner is automatically adjusted to the working mechanism of [28.0℃, 29.5℃]. In order to prevent the old person from using the air conditioner incorrectly, if the old person adjusts the temperature below 26.5℃ again after a period of time, the operation is performed according to the needs of the old person.

[0025] If the air conditioner is used in the time period of 23:00-9:00, the detection time is between 23:00-3:00, most of the old people are in sleep time, and the temperature is set in the range of [29.0℃, 29.5℃] after the air conditioner is started. If the old person adjusts the air conditioner to a low temperature at night again, it is set according to the actual needs. After the time exceeds 2:00, the air conditioner is automatically adjusted to an ultra-low wind speed or a stop state. If the indoor temperature exceeds 29.5℃, the air conditioner is restarted, and if it is kept in the range of [29.0℃, 29.5℃], the air conditioner stops running. In the time period of 5:00-9:00, the air conditioner starts a new air mode. If the air conditioner is started in the time period of 5:00-9:00, the air conditioner is in a cooling mode. If the temperature is set in the range of [28.0℃, 29.5℃], it is run at the set temperature. If the temperature is lower than 28℃, it is run for half an hour, and then [28.0℃, 29.5℃] is used. If the old person adjusts the air conditioner to a low temperature again, it is set according to the actual needs. If it is continuously run to the time period of 5:00-9:00, the air conditioner starts a new air mode and stops the cooling mode.

[0026] Further, the mobile terminal includes a mobile phone, a tablet computer, a smart watch, a smart speaker, a notebook computer, a smart television, a smart panel or a smart screen.

[0027] The application also discloses an air conditioner remote controller, which comprises a communication module, a control module and a storage module. The communication module is in communication connection with the air conditioner and the mobile terminal. 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 conditioner control methods based on different weak old people when executed by the control module.

[0028] The application further discloses an air conditioner comprising the air conditioner remote controller, a condenser, a fan and a fresh air system. The air conditioner responds to the received control strategy instruction from the air conditioner remote controller, and the condenser, the fan and the fresh air system perform corresponding actions.

[0029] The technical effect of the application is self-evident: new control strategies are proposed based on the health level (different weakness levels) of the old people, which is more beneficial to the old people with different needs in real life. The control strategy data is derived from research data, which more objectively reflects the actual needs of the old people with different weakness levels. The research data counts the neutral temperature and the thermal comfort temperature range of the old people with different weakness levels, which is more meaningful in the field of thermal comfort. This research data is the first time to combine the health level of the old people with the actual thermal comfort needs. At the same time, the research also introduces the habit of the old people using the air conditioner during the day and at night and the fresh air into the air conditioner control strategy, so that the air conditioner control is more in line with the actual needs of the old people. This is of practical significance for the old people with different health levels. The control strategy can let the old people not frequently turn on and off the air conditioner at night, and automatically design the air conditioner on-off program according to their habits, which is beneficial to the rest at night. The level of the old people can be evaluated according to the actual information of the old people, so as to recommend the control scheme. The control strategy also considers the situation that the old people are not good at using the air conditioner. If they press the air conditioner by mistake, the default data according to the research data is used for control. These default data come from the research data of the real society, which prevents the room from being too cold due to the wrong use of the old people, and makes the control more suitable for the aging.

[0037] The application will be further described in conjunction with the following examples, but should not be understood as limiting the above-mentioned subject matter of the application to the following examples. Various replacements and changes can be made according to ordinary technical knowledge and common means in the art without departing from the above-mentioned technical idea of the application, and all of them should be included in the protection scope of the application.

[0038] Example 1

[0039] Referring to Figure 1 , the embodiment provides an indoor thermal comfort air conditioning regulation method based on different frailty levels of the elderly, comprising the following steps:

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

[0041] 2) According to the frailty level label of the elderly, determine the preset exclusive regulation strategy corresponding to the user. Among them, the preset exclusive regulation strategy is designed according to the thermal sensitivity, thermal neutral temperature, thermal comfort temperature range and air conditioning use habit of different frail elderly.

[0042] 3) The air conditioner executes corresponding actions in response to the received regulation strategy instruction.

[0043] Example 2

[0044] The main content of this embodiment is the same as that of example 1, wherein, referring to Figure 2 , in step 1), five indexes of weight loss, self-frailty assessment, poor endurance and physical ability, slow action and low physical activity level are used for division. The above three or more characteristics are divided into frail period. One or two of the above characteristics are divided into pre-frail period. The above five characteristics do not exist and are divided into non-frail period.

[0045] Example 3

[0046] The main content of this embodiment is the same as that of example 1 or 2, wherein, referring to Figure 3 , Figure 4 and Figure 5 , the regulation strategy for non-frail elderly in this embodiment is marked as regulation strategy I. The regulation strategy for pre-frail elderly is marked as regulation strategy II. The regulation strategy for frail elderly is marked as regulation strategy III.

[0047] In regulation strategy I, when the air conditioner starts, the device is started according to the temperature setting of the user, and the time information is automatically detected at the same time:

[0048] If the time is between 9:00-23:00, the temperature is set in the range of [26.0℃, 28.0℃], the indoor temperature control is carried out according to the user's temperature preference. If the user's set temperature is in the range of [24.0℃, 26.0℃], the air conditioner runs in a cool environment for 1 hour, and then automatically adjusts to the temperature range of [26.0℃, 28.0℃]. If the user lowers the temperature again after experiencing the indoor temperature of [26.0℃, 28.0℃] for a period of time, the return air temperature is kept in 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 misusing the air conditioner. If the user adjusts the temperature below 24.0℃ again after a period of time, the operation is carried out according to the user's needs.

[0049] If the air conditioner is used in the time period of 23:00-9:00, the detection time is between 23:00-3:00, most users are in sleep time, the temperature is set in the range of [28.0℃, 30.0℃] after the air conditioner starts. If the user adjusts the air conditioner to a low temperature at night again, it is set according to the actual needs. After the time exceeds 3:00, the air conditioner is automatically adjusted to an ultra-low wind speed or a stop state. If the indoor temperature exceeds 30.0℃, it is restarted. If it is kept in the range of [28.0℃, 30.0℃], the air conditioner stops running. In the time period of 5:00-9:00, the air conditioner starts the new air mode. If the air conditioner is started in the time period of 5:00-9:00, it is in cooling mode. If the temperature is set in the range of [28.0℃, 30.0℃], it is run at the set temperature. If the temperature is lower than 28.0℃, it is automatically adjusted 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 low temperature again, it is set according to the actual needs. If it is continuously run to the time period of 5:00-9:00, the air conditioner starts the new air mode and stops the cooling mode.

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

[0051] If the time is between 9:00-23:00, the temperature is set in the range of [27.0°C, 28.0°C], and the indoor temperature control is performed according to the user's temperature preference. If the user's set temperature is in the range of [24.5°C, 27.0°C], the air conditioner runs in a cool environment for 1 hour, and then automatically adjusts the temperature range of [27.0°C, 28.0°C]. If the user again reduces the temperature after experiencing the indoor temperature of [27.0°C, 28.0°C] for a period of time, the return air temperature is kept in the range of [24.5°C, 27.0°C]. If the user sets the temperature below 24.5°C, the air conditioner automatically adjusts to the working mechanism of [27.0°C, 28.0°C]. To prevent the user from misusing the air conditioner, if the user again adjusts the temperature below 24.5°C after a period of time, the air conditioner is operated according to the user's needs.

[0052] If the air conditioner is used in the time period of 23:00-9:00, the detection time is between 23:00-3:00, most users are in sleep time, and the temperature is set in the range of [28.0°C, 29.5°C] after the air conditioner is started. If the user adjusts the air conditioner to a lower temperature at night, it is set according to the actual needs. After the time exceeds 3:00, the air conditioner is automatically adjusted to an ultra-low wind speed or a stop state. If the indoor temperature exceeds 29.5°C to restart, if it is kept in the range of [28.0°C, 29.5°C], the air conditioner stops running. In the time period of 5:00-9:00, the air conditioner starts the new air mode. If the air conditioner is started in the time period of 5:00-9:00, it is in the cooling mode. If the temperature is set in the range of [28.0°C, 29.5°C], it is run at the set temperature. If the temperature is lower than 28.0°C, it is run for half an hour at the set temperature, and then [28.0°C, 29.5°C] If the user again adjusts the air conditioner to a lower temperature, it is set according to the actual needs. If it is continuously run to the time period of 5:00-9:00, the air conditioner starts the new air mode and stops the cooling mode.

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

[0054] If the time is between 9:00-23:00, the temperature is set in the range of [28.0°C, 29.5°C], the indoor temperature control is performed according to the temperature preference of the old person. If the set temperature of the old person is in the range of [26.5°C, 28.0°C], the air conditioner is operated in the cool environment for 1 hour, and then the temperature range of [28.0°C, 29.5°C] is automatically adjusted. If the indoor temperature of [26.5°C, 28.0°C] is experienced for a period of time, the old person lowers the temperature again, the return air temperature is kept in the range of [26.5°C, 28.0°C]. If the user sets the temperature below 26.5°C, the air conditioner is automatically adjusted to the working mechanism of [28.0°C, 29.5°C]. In order to prevent the old person from using the air conditioner incorrectly, if the old person adjusts the temperature below 26.5°C again after a period of time, the operation is performed according to the needs of the old person.

[0055] If the air conditioner is used in the time period of 23:00-9:00, the detection time is between 23:00-3:00, most of the old people are in the sleep time, and the temperature is set in the range of [29.0°C, 29.5°C] after the air conditioner is started. If the old person adjusts the air conditioner to a low temperature at night again, it is set according to the actual needs. After the time exceeds 2:00, the air conditioner is automatically adjusted to an ultra-low wind speed or a stop state. If the indoor temperature exceeds 29.5°C, the air conditioner is restarted, if it is kept in the range of [29.0°C, 29.5°C], the air conditioner stops running. In the time period of 5:00-9:00, the air conditioner starts the new air mode. If the air conditioner is started in the time period of 5:00-9:00, the air conditioner is in the cooling mode. If the temperature is set in the range of [28.0°C, 29.5°C], it is operated at the set temperature. If the temperature is lower than 28.0°C, the set temperature is operated for half an hour, and then [28.0°C, 29.5°C] is used. If the old person adjusts the air conditioner to a low temperature again, it is set according to the actual needs. If it is continuously operated to the time period of 5:00-9:00, the air conditioner starts the new air mode and stops the cooling mode.

[0056] Example 4:

[0057] The main content of the embodiment is the same as any one of embodiments 1-3, wherein the embodiment is based on a survey data, and the survey finds that the elderly have different thermal neutrality temperature, thermal comfort temperature range and air conditioning use time at different frailty levels. The embodiment designs an indoor temperature control method for the elderly with different frailty levels based on the survey data. The embodiment uses Fried's frailty phenotype classification method to divide the elderly into three categories of non-frail period, pre-frail period and frail period according to walking speed, weight loss, grip strength, activity level and self-assessed fatigue. The neutral temperature and comfort temperature range come from the survey data of hot summer and cold winter regions. The survey includes 394 elderly people, and their physical parameters are measured as the calculation of determining the frailty level. At the same time, the indoor temperature is measured, and the thermal sensation vote data of the elderly are recorded to calculate their thermal neutrality temperature and thermal comfort temperature range. The thermal sensation vote adopts the ASHRAE seven-point thermal sensation scale (cold-3, cold-2, slightly cold-1, neutral-0, slightly hot+1, hot+2, hot+3).

[0058] The frailty classification method used in the present application is the frailty standard formulated by Fried, which is simple and easy to use, and is often used for primary assessment of the frailty degree of the elderly. In the assessment, five indexes are mainly used for calculation, including: 1) weight loss; 2) self-assessment of frailty; 3) poor endurance and physical ability; 4) slow action; 5) low physical activity level. Frail period is defined as having three or more of the above characteristics; pre-frail period is defined as having one or two of the above characteristics; and non-frail period is defined as not having the above five characteristics. The survey counted the thermal sensation votes of 394 elderly people in the home environment, and divided them into three different frailty levels according to their physical parameters.

[0059] Referring to Figure 6 and Figure 7 , in step 2), thermal sensitivity and neutral temperature can be obtained by linear regression of thermal sensation vote and operating temperature. Through linear regression, the functional relationship between the neutral temperature of the elderly with different frailty degrees and their thermal sensation vote and operating temperature is calculated, and a step of 0.5°C is used to average the data by using a weighted method. Figure 6is the linear regression plot of the average thermal sensation vote of the elderly with different degrees of weakness, and the calculation formula is shown in formulas 1, 2 and 3. The results show that the neutral temperature of the non-weak elderly is 25.8℃, the neutral temperature of the pre-weak elderly is 26.9℃, and the neutral temperature of the non-weak elderly is 27.9℃. The slope of the average thermal sensation vote of the non-weak elderly is 0.1139, the slope of the average thermal sensation vote of the pre-weak elderly is 0.2001, and the slope of the average thermal sensation vote of the weak elderly is 0.3399. Therefore, the lower the slope, the lower the thermal sensitivity, and in particular, the weak elderly are particularly sensitive to the low air conditioning temperature in summer, so special attention should be paid to the design of avoiding low air conditioning temperature for their needs.

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

[0061] Non-weak elderly:

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

[0063] Pre-weak elderly:

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

[0065] Weak elderly:

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

[0067] Where: MTSV is the average 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 the users are satisfied with the thermal environment. In addition, due to the special needs of the elderly, ASHRAE recommends that the comfort zone of the elderly should be at least 90%. The present application also takes 90% as the comfort temperature interval of the elderly. Through the regression model represented by formulas 1, 2 and 3, the comfort temperature intervals of the elderly with three degrees of weakness are determined as follows: 21.3℃ to 30.1℃ for non-weak elderly, 24.3℃ to 29.3℃ for pre-weak elderly, and 26.4℃ to 29.3℃ for weak elderly. According to the Chinese standard GB / T 50785, in the hot summer and cold winter area of China, when the clothing thermal resistance is 0.5 clo and TSV = -0.5, T min= 24.0 °C, T max = 30.0 °C. Thus, the lower limit of temperature for non-vulnerable elderly is set to 24.0 °C and the upper limit of temperature is set to 30.0 °C, as shown in the thermal comfort zone in Figure 6

[0069] Meanwhile, the temperature setting of air conditioner is generally 0.5 °C as a step. The temperature range that can be recognized by air conditioner controller is calculated by rounding method. Therefore, the final comfort temperature range of different vulnerable levels of elderly is: the comfort temperature range of non-vulnerable elderly is [24.0 °C, 30.0 °C], the comfort temperature range of pre-vulnerable elderly is [24.5 °C, 29.5 °C], and the comfort temperature range of vulnerable elderly is [26.5 °C, 29.5 °C]. The neutral temperature is: the neutral temperature of non-vulnerable elderly is 26.0 °C, the neutral temperature of pre-vulnerable elderly is 27.0 °C, and the neutral temperature of vulnerable elderly is 28.0 °C.

[0070] In order to consider the energy saving of air conditioner, the temperature range of air conditioner is set to the temperature range from the neutral temperature to the upper limit of the comfort temperature range in the environment where the thermal vote is [0, 0.5] slightly hot and can meet the thermal comfort demand of elderly, which is the final set temperature range of air conditioner. That is, the set temperature range of air conditioner of non-vulnerable elderly is [26.0 °C, 30.0 °C], the set temperature range of air conditioner of pre-vulnerable elderly is [27.0 °C, 29.5 °C], and the set temperature range of air conditioner of vulnerable elderly is [28.0 °C, 29.5 °C].

[0071] Meanwhile, the time and frequency of air conditioner use of elderly with different vulnerable levels are counted in the investigation. Because non-vulnerable elderly prefer to go out during the day, the daytime air conditioner use rate of non-vulnerable elderly is lower than that of vulnerable elderly, as shown in Figure 7 At night, the air conditioner use rate of non-vulnerable elderly is higher than that of vulnerable elderly. It is found in the statistics that elderly will not use air conditioner all day long according to their work and living habits. In hot summer, they will stop using air conditioner for a period of time after dinner or after going out for a walk. After 2:00-4:00 in the morning, some elderly will use air conditioner according to the actual situation. Vulnerable elderly will greatly reduce the use of air conditioner at 2:00, and pre-vulnerable and non-vulnerable elderly will reduce the use of air conditioner at 2:00-4:00. They do not want to turn on air conditioner all night, which is more obvious in vulnerable elderly. Meanwhile, most elderly will use air conditioner and open window for ventilation at [5:00, 9:00] in the morning, at which time they generally do not consider the high and low of outdoor temperature. They hope that the room can be ventilated to maintain health, because it is the time with the lowest temperature and the best air in a day.
