Description

  The present invention relates to an individual air conditioning device that individually regulates the temperature of air blown from under the floor.

  In recent years, in offices where IT has been advanced and OA equipment has increased, the amount of heat generation has increased, and indoor air conditioning tends to be forced to increase. For this reason, the conventional ceiling blow-off air conditioning has problems such as that the air directly hit it is too cold, the sensible temperature changes depending on the location of the room, the direction of the wind and the unevenness of the air volume. In addition, floor blow-off air conditioning directly affects the living area from below the floor, so it is possible to keep the room at a comfortable temperature and set the air volume low even at high cooling air supply temperatures, contributing to energy conservation. It is also known to (see, for example, Patent Documents 1 and 2).

However, in such floor blow-off air conditioning, cold air is blown out at the foot during cooling, and the cold air stays in the vicinity of the floor surface, which may cause the foot to become too cold, especially for women. It was. Therefore, a system has been developed that prevents the cold air from blowing out under the feet during cooling by eliminating the height of the blowing position and the air volume at which the cold air blows out, and eliminates excessive cooling of the feet (for example, , See Patent Document 3). Also, with these technologies, the height of the position of the air outlet is adjusted and used personally so that the cool air is blown out near the face when seated, or the cool air is blown directly onto a heating element such as an OA device. A technology that can greatly increase the degree of freedom in use, such as being used for cooling, has been disclosed.

  As air conditioning methods, ceiling blown air conditioning and floor blown air conditioning are known, but ceiling blown air conditioning has a long distance between the user and the blower because the blower is on the ceiling, and the temperature in a predetermined area in the room It is not suitable for individual adjustment. On the other hand, in the floor air-conditioning, the distance between the user and the air outlet is short because the air outlet is on the floor, and the wind acts directly on the user from under the floor, so the temperature in a predetermined area in the room is individually adjusted. It is thought that it is suitable for. However, in the conventional floor air-conditioning, the height and air volume of the air outlet can be individually adjusted, but the temperature of the air exiting from the air outlet cannot be adjusted.

  In view of the above problems, an object of the present invention is to individually adjust the temperature of air blown from a floor outlet to improve the comfort of indoor air conditioning.

  In order to solve the above-described problems, the present invention provides an individual air conditioning apparatus, a pre-air adjustment unit that adjusts the temperature of the entire room, a mixing adjustment unit that individually adjusts the temperature of a predetermined area in the room, and a pre-air adjustment And a floor blowing section for blowing out the air adjusted by the mixing adjustment section from the floor. In the present invention, the temperature of the air blown out from the floor blowing section can be individually adjusted by mixing the air whose temperature has been adjusted by the preliminary air adjusting section and the air that has not been adjusted by the mixing adjusting section. .

Thereby, this invention becomes possible [adjusting the temperature of the mixed air supplied to a predetermined area | region] from a floor blowing part.

  The mixing valve opening degree control unit is provided in the temperature control unit, and controls the opening degree of the mixing valve based on the temperatures of the adjusted air, the return air, and the mixed air detected by the temperature detection unit. The temperature of the conditioned air or mixed air supplied to a predetermined area in the room can be changed by adjusting the opening of the mixing valve.

  Moreover, the said mixing adjustment part may have an air intake means which takes in the said return air to said 2nd channel | path. The air intake means takes the return air from the room into the second passage, and flows the return air to the third passage. Therefore, this invention can self-suck return air according to the opening degree of a mixing valve by providing an air intake means.

  In addition, the mixing adjustment unit 400 may be provided with a fan 301 that is an air intake unit (not shown) that takes the indoor air 15 a into the second passage 403 in the second passage 403. By providing the fan 301, the first embodiment can self-suck the indoor air 15 a according to the opening degree of the mixing damper 401. Further, the floor blowing unit 300 may be provided with a fan 301 in order to blow out the mixed air 16 and the adjusted air 14 from the floor blowing port 303 to the room 8. For example, an axial fan may be used as the fan 301.

  The opening degree of the mixing damper 401 is adjusted by the temperature control unit 405. In the mixed air 16, the opening degree of the mixing damper 401 is adjusted, the amount of mixing of the adjusted air 14 and the return air 15 having different temperatures is changed, and as a result, the temperature is adjusted. As a result, the present invention can individually change the temperature of the mixed air 16 supplied from the floor outlet 303 for each floor outlet 303, so that the temperature of each predetermined region in the room 8 can be adjusted. it can.

  The temperature control unit 405 is provided in the control unit 13 in the double floor 9 and is connected to a plurality of mixing dampers 401 provided under each floor outlet 303 via communication lines. Further, the individual air conditioner 1 of the first embodiment is provided with an input unit 6 (see FIG. 1). FIG. 3 is a plan view illustrating the input unit 6 according to the first embodiment. As shown in FIG. 1, the input unit 6 may be provided with an input unit 6 that receives the set temperature of the entire room, or may be provided for each predetermined area. The input unit 6 receives the set temperature of the mixed air 16 supplied from the floor outlet 303 to a designated area in a predetermined area of the room 8. The designated area is an area for supplying the mixed air 16 in a predetermined area of the room 8 designated by the user. If the opening degree of each mixing damper 401 is adjusted by the temperature control unit 405 based on the temperature information received by the input unit 6, the temperature control unit 405 allows the air volume of the adjusted air 14 and the indoor air 15 a to flow into the third passage 404. Thus, the temperature of the mixed air 16 can be controlled. As a result, the individual air conditioner 1 according to the first embodiment sets the temperature of the mixed air 16 supplied from the floor outlet 303 individually by the input unit 6 and individually changes the temperature of each predetermined region in the room 8. be able to.

  In addition, in the temperature information received by the input unit 6, air mixing by the mixing adjustment unit 400 is not performed in a region other than the designated region designated by the user from the predetermined region in the room 8. That is, as shown in FIG. 4, the mixing damper 401 closes the end of the second passage 403, and the floor outlet 303 blows out only the adjusted air 14 from the first passage 402. Detailed processing of the temperature control unit 405 will be described later.

  Next, the mixing adjustment unit 400 adjusts the ratio of mixing the adjusted air 14 and the return air 15 to adjust the temperature of the mixed air 16. The relationship between the temperature of the mixed air 16 supplied to a predetermined area set in advance by the user, the temperature of the adjusted air 14 and the return air 15, and the air volume of the adjusted air 14 and the return air 15 is preset and standardized. Yes. The ratio of the air volume for mixing the adjusted air 14 and the return air 15 is determined by an expression standardized by the temperature of the mixed air 16 supplied to the predetermined region, the temperature of the adjusted air 14, and the temperature of the return air 15. . Therefore, the individual air conditioning device 1 has an effect of being easily commercialized. The ratio of the adjusted air 14 to be mixed and the indoor air 15a is determined by the following equation (1).

（式中、t₁は調整空気１４の温度、t₂は指定領域に供給する混合空気１６の設定温度、t₃は還気１５の温度、Q₁は調整空気１４の風量、Q₂は還気１５の風量である）

(Where t ₁ is the temperature of the adjusted air 14, t ₂ is the set temperature of the mixed air 16 supplied to the specified area, t ₃ is the temperature of the return air 15, Q ₁ is the air volume of the adjusted air 14, and Q ₂ is the return The air volume of Qi 15

  However, the temperature setting of the mixed air 16 by the user is not indispensable, and a preset temperature of the general room 8, for example, 22 degrees during cooling is set in advance as the temperature of the mixed air 16, and the temperature of the mixed air 18 (1) The opening degree of the mixing damper 401 may be controlled by the temperature control unit 405 based on the equation. In this case, the input unit 6 that receives the set temperature of the mixed air 16 can be omitted.

  Moreover, in Example 1, as shown in FIG. 5, the electric heater 20 can be further provided and the temperature of the mixed air 16 blown off from the floor can be finely adjusted. Thereby, it is possible to meet the temperature requirements of each user and improve the comfort of the room 8.

  FIG. 6 is a functional block diagram of the individual air conditioning device 1 according to the first embodiment. The control unit 13 can be realized by a computer including a CPU, a memory, and the like, and a program executed on the computer. The control unit 13 includes a temperature control unit 405.

  A configuration in the control unit 13 will be described. The temperature control unit 405 in the control unit 13 includes a temperature information acquisition unit 405a, a specified region information acquisition unit 405d, a mixed air ratio determination unit 405b, and a mixing valve opening degree control unit 405c. Hereinafter, the configuration of the control unit 13 will be described.

  The temperature information acquisition unit 405 a acquires the temperature detected by the temperature detection unit 5. The designated area information acquisition unit 405d acquires the temperature of the mixed air 16 supplied to the designated area, which is received by the input unit 6. The mixed air ratio determining unit 405b determines the ratio of the adjusted air 14 and the indoor air 15a that form the mixed air 16. The mixing valve opening degree control unit 405 c adjusts the opening degree of the mixing damper 401.

  FIG. 7 is a control flow diagram of the individual air conditioning device 1 according to the first embodiment. The individual air conditioner 1 will be specifically described below with reference to the control flowchart shown in FIG.

  In step S01, the temperature information acquisition unit 405a acquires the temperature information detected by the temperature detection unit 5. For example, the temperature information detected by the temperature detection unit 5 is that the indoor air 15a is 29 degrees, the preset temperature in the room is 25 degrees, the adjusted air 14 is 24 degrees, and the temperature of a predetermined area in the room 8 is 29 degrees. Information. If acquisition of temperature information is completed, it will progress to step S02.

  In step S02, the designation information acquisition unit 405d acquires temperature information of the designation area. The designation information acquisition unit 405d acquires information from the input unit 6. For example, when the user is in the area A where the temperature of the room 8 is 29 degrees, the temperature of the area A is changed to 26 degrees. In this case, the set temperature of the mixed air 16 supplied to the designated area received by the input unit 6 is 26 degrees. An image of the designated area A is shown in FIG. When the acquisition of the temperature information of the designated region is completed, the process proceeds to step S03.

In step S03, the ratio of the mixed air 16 supplied to the designated area by the mixed air ratio determining unit 405b is determined. The mixed air 16 mixes the adjusted air 14 having different temperatures and the indoor air 15a as the return air 15. Therefore, based on the adjusted air 14 detected by the temperature detection unit 5 and the room air 15a, the mixed air ratio determination unit 405b is set to the set temperature of the mixed air 16 supplied to the designated area received by the input unit 6. Determines the ratio of the adjusted air 14 to be mixed and the indoor air 15a by the above-described equation (1).

  For example, the temperature of the adjusted air 14 detected by the temperature detector 5 is 24 degrees, the indoor air 15a is 29 degrees, and the set temperature of the mixed air 16 received by the input section 6 is 26 degrees. In order to set the mixed air 16 to 26 degrees, the mixed air ratio determination unit 405b determines that 40% of the adjusted air 14 and 60% of the indoor air 15a are mixed by the equation (1). When the ratio of the mixed air 16 in the designated area is determined, the process proceeds to step S04.

  In step S04, the mixed air 16 is supplied to the designated area. The mixing valve opening degree control unit 405c adjusts the opening degree of the mixing damper 401 based on the mixed air ratio determined in step S03, and mixes the adjusted air 14 and the indoor air 15a to form the mixed air 16. The mixed air 16 is supplied from the floor outlet 303 to the designated area. For example, when the mixing adjustment unit 400 mixes 40% of the adjustment air 14 and 60% of the room air 15a to form a mixed air 16 of 26 degrees, the mixing damper 401 has a second passage 403 through which the room air 15a flows. Open in the direction of spreading to the side. 40% of the adjusted air 14 and 60% of the indoor air 15a flow out into the third passage 404 by the opened mixing damper 401, and a mixed air 16 of 26 degrees is formed. The formed mixed air 16 of 26 degrees is blown out from the floor outlet 303 to a designated area in the room 8. When the mixed air 16 is supplied to the designated area, the process proceeds to step S05.

  In step S05, the adjusted air 14 is supplied to a region other than the designated region. The adjusted air 14 adjusted so that the room 8 has a temperature set in advance to an area other than the designated area of the room 8 which is the information acquired in step S02 is blown out from the floor outlet 303, and is outside the designated area. Bring the area to a preset temperature. For example, when the designated area is A, the temperature of the area other than the designated area A needs to be a preset temperature of 25 degrees. Since the indoor air 15a is 29 degrees, the adjusted air 14 of 24 degrees is blown out from the floor blowing section 300 on the floor 7 other than the designated area A.

  As described above, the individual air conditioning apparatus 1 according to the first embodiment can individually adjust the temperature of the air supplied from the floor blowing unit 300 and improve the comfort of the indoor air conditioning.

  In the first embodiment, as illustrated in FIG. 4, in the floor blowing unit 300, the fan 301 is provided below the floor blowing port 303, and the mixing damper 401 is provided between the first passage 402 and the second passage 403. ing. On the other hand, in the second embodiment, as shown in FIG. 8, the fan 301 is provided in the first passage 402 and the second passage 403. As in the first embodiment, a fan 301 (not shown) may be further provided below the floor outlet 303. In the second embodiment, a check damper 501 is provided in each of the first passage 402 and the second passage 403. When the fan 301 rotates, the check damper 501 opens, and when the fan 301 stops, the damper 501 closes. As shown in FIG. 8, since the fan 301 provided in the first passage 402 is rotating, the check damper 501 provided in the first passage 402 is opened. On the other hand, since the fan 301 provided in the second passage 403 is stopped, the check damper 501 provided in the second passage 403 is closed. According to the individual air conditioning apparatus of the second embodiment, by providing the fans 301 in the respective passages, the indoor air 15a and the regulated air 14 can be self-primed according to the opening degree of each check damper 501.
