  The selection of weak dehumidification or weak humidification may correspond to seasons such as weak dehumidification in summer and autumn, weak humidification in winter and spring, etc., and a reference humidity value (for example, 50%) of the outside air is determined and the reference humidity is determined. It may be set so that it is weakly dehumidified if the current outside air humidity detected by the building outside temperature and humidity sensor K1 is higher than the value, and weakly humidified if it is lower. Further, for example, it may be set so that weak dehumidification is selected when strong dehumidification has been operated until then, and weak humidification is selected when strong dehumidification has been operated.

It is. FIG. 8 is a table showing switching conditions when both temperature and humidity are set in the entire building air-conditioning high energy saving operation.

  The whole building air-conditioning high energy saving operation is basically set to perform “basic whole building air-conditioning operation” and switch to “air blowing” when certain conditions are met. The vertical items in the table indicate external environmental conditions and operation modes of the building 100. “Tg” in FIG. 7A indicates the temperature outside the building (outside building temperature), and “Mg” in FIG. 7B indicates the humidity outside the building (outside building humidity).

  As shown to (a) of FIG. 7, the switching conditions 16-18 have shown the switching conditions at the time of setting only temperature in the whole building air-conditioning high energy saving operation.

  Under the switching condition 22, the control unit 34 includes the building outside temperature Tg transmitted from the building outside temperature and humidity sensor K1 (see FIG. 3) from the minimum value Tmin to the maximum value Tmax (Tmin ≦ Tg ≦ Tmax). ), And when it is determined that the outside humidity Mg is included in the maximum value Mmax from the minimum value Mmin of the set humidity range (Mmin ≦ Mg ≦ Mmax), “Blow” is set to be selected. .

  The switching conditions 23 to 30 are set to execute the above-described “basic entire building air conditioning operation” when at least one of the outside building temperature Tg and the outside building humidity Mg is not included in the setting range. That is, in the switching conditions 23 to 30, since outside air is not included in the setting range, no air is blown.

<Entire air conditioning and energy-saving operation>
The whole building air-conditioning low energy saving operation is an operation method that can save energy while making the environment inside the building an environment set by the user. Whole building air-conditioning low energy saving operation is different from basic whole building air-conditioning operation in that air is blown according to the environment of the outside air. In addition, the whole building air-conditioning low energy saving operation is an operation method that can make the environment inside the building more comfortable than the whole building air conditioning high energy saving operation, although the energy saving efficiency is lower than the whole building air conditioning high energy saving operation.

  FIG. 9 is a table showing switching conditions when only the temperature is set in the entire building air-conditioning low energy saving operation. As shown in FIG. 9, the switching conditions 31 to 39 are set so as to be determined based on the outside temperature and the inside temperature of the building 100 in the entire building air-conditioning low energy saving operation.

Has been. In other words, as shown in the switching condition 16 in FIG. 7, in the above-described whole building air-conditioning high energy-saving operation, if outside air is included in the set temperature range, air is blown immediately. Since priority is given to the inclusion in the temperature range, the energy efficiency is lower than in the entire building air-conditioning high energy-saving operation, but the interior of the building can be made comfortable.

  In the switching conditions 34 to 39, when the control unit 34 determines that the building outside temperature Tg transmitted from the building outside temperature and humidity sensor K1 (see FIG. 3) exceeds the maximum value Tmax of the set temperature range (Tmax <Tg). Alternatively, when it is determined that the building outside temperature Tg is less than the minimum value Tmin of the set temperature range (Tg <Tmin), the above-described “basic entire building air conditioning operation” is set to be executed. That is, in the switching conditions 34 to 39, since the outside air is not included in the set temperature range, no air is blown.

  FIG. 10 is a table showing switching conditions when only humidity is set in the entire building air-conditioning low energy saving operation. As shown in FIG. 10, the switching conditions 40 to 48 are set so as to be determined based on the humidity outside the building 100 and the humidity inside the building 100 in the entire building air-conditioning low energy saving operation.

  Under the switching condition 40, the control unit 34 includes the outside building humidity Mg transmitted from the outside building temperature and humidity sensor K1 (see FIG. 3) from the minimum value Mmin to the maximum value Mmax of the set temperature range (Mmin ≦ Mg ≦ Mmax). And the in-building humidity Mr transmitted from the in-building temperature / humidity sensor K2 (see FIG. 3) is included in the set humidity range from the minimum value Mmin to the maximum value Mmax (Mmin ≦ Mr ≦ Mmax). In such a case, “Blow” is selected.

  In the switching condition 41 and the switching condition 42, the control unit 34 includes the outside humidity Mg transmitted from the outside temperature / humidity sensor K1 (see FIG. 3) from the minimum value Mmin to the maximum value Mmax of the set humidity range (Mmin). ≦ Mg ≦ Mmax), but when it is determined that the building humidity Mr is not included in the set temperature range (Mmax <Mr, Mr <Mmin), the above-mentioned “basic whole building air conditioning operation” is set to be executed. Has been. In other words, as shown in the switching condition 19 in FIG. 7, the entire building air-conditioning and high energy-saving operation immediately blows if the outside air is within the set humidity range, but in this whole building air-conditioning and low energy-saving operation, the humidity inside the building is set. Since priority is given to the inclusion in the humidity range, the energy saving efficiency is lower than in the entire building air-conditioning high energy-saving operation, but the interior of the building can be made comfortable.

  In the switching conditions 43 to 48, when the control unit 34 determines that the outside building humidity Mg transmitted from the outside building temperature and humidity sensor K1 (see FIG. 3) exceeds the maximum value Mmax of the set humidity range (Mmax <Mg). Alternatively, when it is determined that the humidity outside the building Mg is less than the minimum value Mmin of the set humidity range (Mg <Mmin), the above-described “basic entire building air conditioning operation” is set to be executed. That is, in the switching conditions 43 to 48, since the outside air is not included in the set humidity range, no air is blown.

  FIG. 11 is a table showing switching conditions when both temperature and humidity are set in the entire building air-conditioning low energy saving operation. As shown in FIG. 11, there are three switching conditions 49 to 129 (the case where they are included in the setting range, the case where they are exceeded, and the case where they are not satisfied, and since there are four items of temperature or humidity inside and outside the building, 3 4 81) is set so as to be determined based on the temperature and humidity outside the building 100 and the temperature and humidity inside the building 100.

  In the switching condition 49, the outside temperature Tg transmitted from the outside temperature / humidity sensor K1 (see FIG. 3) is included in the switching condition 49 from the minimum value Tmin to the maximum value Tmax (Tmin ≦ Tg ≦ Tmax). ) And the outside humidity Mg is determined to be included in the maximum value Mmax from the minimum value Mmin of the set humidity range (Mmin ≦ Mg ≦ Mmax), and the temperature / humidity sensor K2 in the building (see FIG. 3) It is determined that the in-building temperature Tr transmitted from is included in the maximum value Tmax from the minimum value Tmin of the set temperature range (Tmin ≦ Tr ≦ Tmax), and the in-building humidity Mr is maximum from the minimum value Mmin of the set humidity range When it is determined that the value is included in the value Mmax (Mmin ≦ Mr ≦ Mmax), “blow” is selected.

When it is determined that at least one of them is out of the setting range, the above-described “basic whole building air conditioning operation” is set to be executed. That is, in the entire building air-conditioning high energy-saving operation, as shown in the switching condition 22 in FIG. 8, if the outside air is included in the set temperature range and the set humidity range, air is blown immediately. Since priority is given to including the temperature and humidity inside the building in each setting range, the energy saving efficiency is lower than that of the whole building air-conditioning high energy saving operation, but the inside of the building can be made comfortable.

  In the switching conditions 58 to 129, when the control unit 34 does not include the building outside temperature Tg transmitted from the building outside temperature and humidity sensor K1 (see FIG. 3) in the set temperature range, or the outside building humidity Mg is the set humidity. When not included in the range, it is set to execute the “basic whole building air conditioning operation”. That is, since the outside air is not included in the set temperature range and the set humidity range, no ventilation is performed.

  Next, operation | movement of the air conditioning system 1 which concerns on this embodiment is demonstrated using a flowchart.

  When it is determined that the button of the individual operation unit is ON (step S5, YES), the control unit 34 selects the operation mode that is ON. The control unit 34 transmits the selected operation mode selection signal to the operation mode switching means 35. When receiving the operation mode selection signal transmitted from the control unit 34, the operation mode switching means 35 transmits an operation signal to the corresponding operation mode and transmits a stop signal to the operation mode not corresponding to the operation mode selection signal.

  In each of steps S14, 16, and 17, the control unit 34 transmits the selected operation mode selection signal to the operation mode switching means 35. When receiving the operation mode selection signal transmitted from the control unit 34, the operation mode switching means 35 transmits an operation signal to the corresponding operation mode and transmits a stop signal to the operation mode not corresponding to the operation mode selection signal. After selecting the operation mode, the control unit 34 returns to step S1 (see FIG. 12).

  Further, as shown in FIG. 14, the control unit 34 determines whether or not the set humidity range button 62 is ON (step S21). When it determines with the setting humidity range button 62 being ON (step S21, YES), the control part 34 determines whether the humidity signal was received from the temperature / humidity sensor K2 in a building (step S22).

  If the temperature and humidity inside the building 100 are not included in the set temperature range and set humidity range set by the user in the basic whole building air conditioning operation shown above, air conditioning is performed so that they are included in this range. If so, drive to maintain that condition.

<Operation of air-conditioning high energy-saving operation in the entire building>
As shown in FIG. 12, when it is determined in step S3 that the high energy saving button is ON (step S3, YES), the control unit 34 controls the entire building air conditioning high energy saving operation as shown in FIG. I do. Here, the case where only the temperature is set in the entire building air-conditioning high energy saving operation will be mainly described.

  The control unit 34 determines whether both the set temperature range button and the set humidity range button are ON (step S31).

  When neither the set temperature range button nor the set humidity range button is ON (step S31, NO), the control unit 34 determines whether only the set humidity range button is ON (step S32). .

  When only the set humidity range button is not ON (step S32, NO), the control unit 34 determines whether only the set temperature range button is ON (step S33).

  When only the set temperature range button is ON (step S33, YES), the control unit 34 determines whether a temperature signal has been received (step S34, YES). If only the set temperature range button is not ON (step S33, NO), that is, if neither the set temperature range button nor the set humidity range button is ON, the process returns to step 31.

  When it determines with having received the temperature signal (step S34, YES), the control part 34 determines whether the building outside temperature Tg measured by the building outside temperature humidity sensor K1 is contained in a setting temperature range (step S35). ). When it is determined that the temperature signal is not received (step S34, NO), the determination in step S34 is repeated.

  If it is determined that the building outside temperature Tg is included in the set temperature range (step S35, YES), the control unit 34 refers to the switching condition stored in advance in the storage unit 33 and selects the blowing (step S36). .

  In step S <b> 36, the control unit 34 transmits the selected operation mode selection signal to the operation mode switching means 35. When the operation mode switching unit 35 receives the operation mode selection signal transmitted from the control unit 34, the operation mode switching unit 35 transmits an operation signal to the corresponding blowing unit 25 and transmits a stop signal to the other operation modes. After selecting the operation mode, the control unit 34 returns to step S1 (see FIG. 12).

  When it is determined that the building outside temperature Tg is not included in the set temperature range (step S35, NO), the process proceeds to step S13 (FIG. 13). That is, when the building outside temperature Tg is not included in the set temperature range, the basic entire building air conditioning operation is performed without blowing.

  When both the set temperature range button 61 and the set humidity range button 62 are ON (step S31, YES), control is performed by setting the temperature and humidity in the entire building air conditioning high energy saving operation (step S37). When the temperature and humidity are set in the entire building air-conditioning and high energy saving operation, as shown in FIG. 8, air is blown only when the outside temperature Tg and outside humidity Mg are included in the setting range. In the case of other conditions, the process moves to step S13 (indicated by the symbol “E”) in FIG. 13 and step S23 in FIG. 14 (indicated by the symbol “F”) to perform the basic entire building air conditioning operation. The detailed operation when the temperature and humidity of the entire building air-conditioning high energy-saving operation are set only adds the humidity condition to the above-described temperature condition, and thus the description thereof is omitted.

  If it is determined that only the set humidity range button 62 is ON (step S32, YES), control is performed with only the humidity set in the entire building air-conditioning high energy saving operation (step S38). In the entire building air-conditioning high energy saving operation, when only the humidity is set, as shown in FIG. 7 (b), air is blown only when the outside humidity Mg is included in the set humidity range. In the case of other conditions, the process moves to step S23 (indicated by the symbol “F”) in FIG. In the case where only the humidity of the entire building air-conditioning high energy saving operation is set, the temperature condition described above is simply replaced with the humidity condition, and thus the detailed operation will not be described.

  In the entire building air-conditioning high energy-saving operation described above, when the building outside temperature Tg is included in the set temperature range, the operation mode of the air conditioner is switched to the blower 25 and the outside air is taken into the building 100 as it is. That is, the air blowing unit 25 takes in the outside air as it is without heating, cooling, dehumidifying and humidifying. The blowing unit 25 consumes less energy than the cooling unit 21, the heating unit 22, the dehumidifying unit 23, and the humidifying unit 24, so that energy saving can be achieved. Further, by taking in the outside air included in the set temperature range, the inside of the building 100 can be air-conditioned in an environment desired by the user. Moreover, since the user can set the temperature range, the burden on the air conditioner can be reduced and the environmental symbiosis effect can be increased.

  Further, in the entire building air-conditioning high energy saving operation, the operation mode is switched based on the switching condition stored in advance, so that the operation burden on the user can be reduced. Moreover, in this embodiment, the inside of the building 100 can be kept in a comfortable state while efficiently taking in the outside air by blowing air, simply by operating the button first.

<Operation of air-conditioning and energy-saving operation throughout the building>
As shown in FIG. 12, when it determines with the low energy saving button having been turned ON in step S4 (step S4, YES), as shown in FIG. 16, the control part 34 controls whole building air conditioning low energy saving operation. I do. Here, the case where only the temperature is set in the entire building air-conditioning low energy-saving operation will be mainly described.

  The control unit 34 determines whether both the set temperature range button 61 and the set humidity range button 62 are ON (step S41).

  When both the set temperature range button 61 and the set humidity range button 62 are not ON (step S41, NO), the control unit 34 determines whether only the set humidity range button 62 is ON (step S41). Step S42).

  When only the set humidity range button 62 is not ON (step S42, NO), the control unit 34 determines whether only the set temperature range button 61 is ON (step S43).

  When only the set temperature range button 61 is ON (step S43, YES), the control unit 34 determines whether a temperature signal is received (step S44). If only the set temperature range button 61 is not ON (step S43, NO), that is, if neither the set temperature range button 61 nor the set humidity range button 62 is ON, the process returns to step 41.

  When it determines with having received the temperature signal (step S44, YES), the control part 34 includes the building outside temperature Tg measured by the building outside temperature / humidity sensor K1 in the set temperature range, and the building inside temperature. It is determined whether the building temperature Tr measured by the humidity sensor K2 is included in the set temperature range (step S45). If it is determined that the temperature signal is not received (step S44, NO), the determination in step S44 is repeated.

  When it is determined that the building outside temperature Tg is included in the set temperature range and the building temperature Tr is included in the set temperature range (step S45, YES), the control unit 34 is stored in the storage unit 33 in advance. The ventilation is selected with reference to the switching condition (step S46).

  In step S <b> 46, the control unit 34 transmits the selected operation mode selection signal to the operation mode switching means 35. When the operation mode switching unit 35 receives the operation mode selection signal transmitted from the control unit 34, the operation mode switching unit 35 transmits an operation signal to the corresponding blowing unit 25 and transmits a stop signal to the other operation modes. After selecting the operation mode, the control unit 34 returns to step S1 (see FIG. 12).

  When it is determined that at least one of the outside building temperature Tg and the inside building temperature Tr is not included in the set temperature range (step S45, NO), the process proceeds to step S13 (FIG. 13). That is, when the building outside temperature Tg is not included in the set temperature range, the basic entire building air conditioning operation is performed without blowing.

  When both the set temperature range button 61 and the set humidity range button 62 are ON (step S41, YES), control is performed by setting the temperature and humidity in the entire building air conditioning high energy saving operation (step S47). When temperature and humidity are set in the entire building air-conditioning high energy-saving operation, as shown in FIG. 11, all of the outside temperature Tg, outside humidity Mg, inside temperature Tr and inside humidity Mr are included in the setting range. Only blow air. In the case of other conditions, the process moves to step S13 (indicated by the symbol “E”) in FIG. 13 and step S23 in FIG. 14 (indicated by the symbol “F”) to perform the basic entire building air conditioning operation. The detailed operation when the temperature and humidity of the entire building air-conditioning high energy-saving operation are set only adds the humidity condition to the above-described temperature condition, and thus the description thereof is omitted.

  If it is determined that only the set humidity range button 62 is ON (step S42, YES), control is performed with only the humidity set in the entire building air-conditioning low energy saving operation (step S48). When only the humidity is set in the entire building air-conditioning low energy saving operation, as shown in FIG. 10, as shown in FIG. 10, air is blown only when the outside humidity Mg is included in the set humidity range and the inside humidity Mr is included in the set humidity range. . In the case of other conditions, the process moves to step S23 (indicated by the symbol “F”) in FIG. In the case where only the humidity of the entire building air-conditioning and low energy saving operation is set, the temperature condition described above is simply replaced with the humidity condition, and thus the detailed operation will not be described.

  In the entire building air-conditioning low energy saving operation described above, when the outside temperature Tg and the inside temperature Tr are included in the set temperature range, the operation mode of the air conditioner is switched to the air blowing means 25 to draw outside air into the building 100. Take in as it is. The blowing unit 25 consumes less energy than the cooling unit 21, the heating unit 22, the dehumidifying unit 23, and the humidifying unit 24, so that energy saving can be achieved. Further, by taking in the outside air included in the set temperature range, the inside of the building 100 can be air-conditioned in an environment desired by the user. Moreover, since the user can set the temperature range, the burden on the air conditioner can be reduced and the environmental symbiosis effect can be increased.

  In the whole building air-conditioning low energy-saving operation, the efficiency of energy saving is inferior to the above-mentioned whole building air-conditioning high energy-saving operation by taking outside air after the temperature inside the building is included in the set temperature range, but it is comfortable. Can be improved.

  In addition, since the operation mode is switched based on the switching condition stored in advance, the operation burden on the user can be reduced. Moreover, in this embodiment, the inside of the building 100 can be kept in a comfortable state while efficiently taking in outside air by simply operating the button first.

  Here, in the conventional air conditioning system, for example, the temperature setting is not a range but a single temperature is set. However, if one temperature is set, the human body adapts to that temperature, and the adaptability to the temperature environment may be reduced. In this regard, according to the present embodiment, for example, the temperature can be set as a range, so that it is possible to prevent a decrease in adaptability to the temperature environment. In addition, for example, by setting the temperature within a range, and blowing air to take outside air into the building 100, the environmental symbiosis effect can be synergistically enhanced.

  Although the embodiments of the present invention have been described above, design changes can be made as appropriate without departing from the spirit of the invention. For example, in the basic all-building air conditioning operation, when the building temperature Tr or the building humidity Mr is included in the setting range, the operation of the air conditioning system 1 is temporarily stopped in order to maintain the environmental condition, and the subsequent determination When it is determined that the building temperature Tr or the building humidity Mr is not included in the set range, the air conditioning system 1 may be operated again.
