In FIG. 3, the same components as those described in the first embodiment are denoted by the same reference numerals , and the description thereof is omitted. 11 is an indoor unit of an air conditioner installed in the store 1, 12 is an outdoor unit of the air conditioner installed outside the store 1, 13 is a refrigerant pipe connecting the indoor unit 11 and the outdoor unit, 33 is a blower, It is installed on the ceiling in the store 1.

  In the store 1, operations such as cooling, heating, and blowing are performed by an air conditioner installed in the store 1, and the temperature in the store 1 is adjusted to be comfortable. However, there is often a temperature difference of about 10 ° C. at the top and bottom of the store 1, and in the case of heating, if it is set optimally at the height of the person's position, the temperature becomes even higher near the ceiling and wasteful heating capacity is used. If the blower 33 is provided on the ceiling in the store 1 as in the present embodiment, the temperature distribution in the store 1 is improved and there is no need to use useless heating capacity.

  Further, the air region distribution of the air conditioner described in the first embodiment or the air blowing port 3 of the air conditioner is not applied to the air curtain 16 in the opening 5 of the refrigeration / frozen showcase 2. Similarly to the above, if the blower 33 is installed so that the air region distribution 34 of the blower 33 does not cover the opening 5 of the refrigeration / frozen showcase 2 installed in the store 1 or the air curtain 16 in the opening 5. Since the intruding air 14 does not enter the opening 5 of the showcase 2, an extra heat load is not applied and energy saving operation is possible. Further, if the blower 33 is arranged on the ceiling in the store 1, the degree of freedom of installing the blower in the room can be expanded, and an extra load is not given to the refrigeration / freezing device, and other than the refrigeration / refrigeration device. The place can be made comfortable.

  Further, although the wind region distribution 34 does not reach the opening 5 or the air curtain 16, if the blower 33 is installed so as to reach the passage 6 on the front surface of the showcase 2, energy saving operation can be performed, and the air in the showcase 2 can be obtained. If the airflow distribution 24 stirs the leakage of the cool air 15 from the curtain 16 to the extent that the dust on the floor does not rise up and mixes with the air in the store 1, the discomfort due to the cold in the passage 6 Can also be eliminated.

  Further, if the ventilation fan described in the first embodiment is provided, the air region distribution 34 can be changed so as not to be applied to the air curtain 16 as in the first embodiment, and the intruding air is introduced into the opening 5 of the showcase 2. Since 14 does not enter, an extra heat load is not applied and energy-saving operation is possible.

  Further, when a large number of showcases 2 are installed in the store 1, if the blower 33 is provided separately from the indoor unit 11 of the air conditioner as in the present embodiment, the blower 33 is provided for each showcase. It is also possible to provide an indoor unit for each showcase, so that low cost, energy saving, and installation corresponding to each showcase are facilitated.

  FIG. 4 is a diagram showing the air region distribution for explaining the air blowing range of the blower, and FIG. 5 is a diagram showing the relationship between the height and the wind speed in the air region distribution. In the figure, 33 is a blower and 34 is an air region distribution. FIG. 4 shows how to view the wind region distribution diagram, where the direct distance H of the blower 33 is 4.5 m, and the hatched portion indicates the blow range when the direct distance H of the blower 33 is 4.5 m. And the wind speed distribution. The wind speed is 100 m / min per scale as the scale is attached.

  FIG. 5 shows the relationship between the air region distribution and the distance when the blower 33 is operated. In the figure, the horizontal axis represents the air blowing range from the position directly below the blower 33, and the vertical axis represents the case where the direct distance H from the blower 33 is 1.5 m, 2.5 m, 3.5 m, 4.5 m, and 5.5 m. It represents the wind speed at each height. It can be seen from the figure that the wind speed decreases and the blowing range increases as the distance H directly below the blades of the blower 33 increases.

  The case where the wind speed distribution and the air blowing range when the wind speed intensity at each height H is changed is height H = 1.5 m will be described. It can be seen that the air blowing range and the wind speed distribution increase as the wind speed increases with the light wind, the weak wind, the medium wind, and the strong wind. Also, 60 Hz is larger than the 50 Hz in both the blowing range and the wind speed distribution. That is, as the direct distance H is increased and the wind speed is increased, the radius of the wind region distribution is increased.

  FIG. 6 is a diagram showing the improvement effect of the temperature distribution in the store due to the operation of the blower. In the figure, the horizontal axis represents the room temperature, and the vertical axis represents the height from the floor at the position directly below the blower. The curve indicated by A in the figure represents the relationship between the vertical temperature distribution in the store before the operation of the blower and the height from the floor. B represents the relationship between the upper and lower temperature distribution in the store and the height from the floor after 1 minute from the fan operation, C after 2 minutes from the fan operation, and D after 3 minutes from the fan operation.

  From the figure, the floor temperature is 17 ° C before the blower operation, and the temperature difference of 28 ° C and the top and bottom in the store is 10 ° C or more at the height of 2.5m from the floor, but only 3 minutes after the blower operation. Is 21 ° C at a floor temperature of 20 ° C and a height of 2.5m from the floor, and the temperature difference is 1 ° C between the upper and lower sides of the store. By operating the blower, the upper and lower temperatures in the store The difference can be greatly reduced, maintaining comfort and energy saving.

  In addition, although the open showcase was demonstrated in this Embodiment 1 and Embodiment 2, even if the thing of the opening / closing type with a glass door is provided in the glass window in which the ventilation area of the air blown out from an air conditioner was provided in the opening part If it is installed so as not to be exposed, less heat is transferred through the glass door, and intrusion of ambient outside air when the glass door is opened can be prevented, so that an extra heat load is not applied and an energy saving effect is obtained.

  Also, H is the distance directly below the floor surface of the air conditioner or blower, V is the air blowing speed of the air conditioner or blower, and L is the distance between the front surface of the refrigerator / freezer and the position directly below the floor surface of the air conditioner or blower. If L is larger as V is larger and L is larger as V is larger so that the air blowing range of the air conditioner or blower does not cover the air curtain of the refrigerator / freezer, Even in the case of an air conditioner or a blower having different air flow settings, it is possible to set an optimal installation position of the air conditioner or blower, and the degree of freedom of installation is expanded. Also, if the distance H directly below the floor, the distance L between the position directly below the floor and the front of the showcase, and the wind velocity V of the blown air are set appropriately, dust and dust on the floor will rise up in the room. Can be suppressed.

  In addition, if only the air outlet of the air conditioner is installed in the store by a duct or the like, the degree of freedom of installation of the air outlet will be further expanded, and the intrusion air load inside the showcase opening due to the intrusion of the outlet air will be increased. An air conditioner that does not increase, can extend the air blowing range outside the opening of the showcase, and can air-condition the portion other than the opening of the showcase to obtain a comfortable room. Can be obtained.

  Moreover, although the air-conditioning apparatus or air blower demonstrated in Embodiment 1 or this Embodiment demonstrated the case where it installed in the indoor ceiling, it may not be a ceiling separately but a side wall may be sufficient. In addition, when the existing air conditioner is installed on the ceiling or side wall of the room, the wind speed is determined by the distance H directly below the floor, the distance L between the position directly below the floor and the front of the showcase, and the wind speed V of the blown air. The showcase may be installed at a position where the area distribution does not reach the opening or the air curtain.

Embodiment 3 FIG.
7 and 8 show the arrangement and operation method of the lighting device and the air conditioner according to Embodiment 3 of the present invention. FIG. 7 is a view showing the arrangement of the air conditioner and the lighting device of the present invention. In the figure, 1 is a store such as a supermarket, 2 is a refrigerated / frozen showcase for storing foods in the opening, 500 is a lighting device installed in the store 1, 503 is a change in input to the lighting device 500 Illumination input control means 511 for changing the brightness in the store 1 is installed in the store 1, air conditioner for air conditioning in the store 1, 513 grasps the operating state of the air conditioner, operation ON / OFF, operation mode, air volume, Air conditioner operation control means for controlling the wind direction and the like, 533 is installed on the ceiling in the store 1 to improve the temperature distribution in the store 1, 543 grasps the operating state of the blower 533, and is turned on / off. Blower operation control means for controlling the number of revolutions, etc., 550 are temperature detection means for detecting the air temperature or ceiling temperature in the vicinity of the lighting device 500.

  FIG. 8 is a diagram showing the relationship between the ambient temperature of illumination and the luminous flux change rate, where the horizontal axis represents the ambient temperature of the fluorescent lamp used in the illumination device 500, and the vertical axis represents the luminous flux change rate. Usually, in a fluorescent lamp, the mercury vapor pressure in the glass tube changes according to the change in the ambient temperature, so that the generation efficiency of ultraviolet rays changes and the luminous flux changes. The change in the luminous flux means that the brightness changes. In the figure, when the luminous flux change rate is 100%, the brightness is the brightest.

  In the figure, an example showing the relationship between the ambient temperature of the fluorescent lamp actually used and the luminous flux change rate is shown by two curves represented by a solid line A and a dotted line B in the figure. In the case of the fluorescent lamp A represented by the solid line A, the luminous flux change rate becomes 100% at an ambient temperature of about 26 ° C., and in the fluorescent lamp B represented by the dotted line B, the luminous flux change rate at an ambient temperature of about 22 ° C. Is 100%, which indicates that the ambient temperature is the optimum ambient temperature and that the illumination efficiency is the highest. In either case, it can be seen that if the ambient temperature deviates from this optimum ambient temperature, the rate of change in luminous flux decreases rapidly and the efficiency becomes extremely poor.

  FIG. 9 is a diagram showing an operation control flowchart of the lighting device and the air conditioner. In the figure, STEP 1 is a start, STEP 2 is a temperature detection step for detecting the air temperature or ceiling temperature in the vicinity of the lighting device by the temperature detection means 550, and STEP 3 is detected in STEP 2 by the air conditioner operation control means 513 or the blower operation control means 543. Step 4 for comparing whether the temperature is within a preset temperature range, STEP 4 is the illumination input control means 503 based on the comparison temperature information from the air conditioner control means 513 or blower operation control means 543. The step of changing the input to the illumination by STEP5, the step of changing the brightness of the illumination according to the input changed in STEP4, STEP6 is within the set temperature range from the air conditioner control means 513 or the blower operation control means 543 Air conditioning based on temperature comparison information Location step of the ON operation (including blower) (or OFF), Step 7 is a step of directing the wind blowing air of the air conditioner 511 in the direction of the illumination device.

Therefore, to detect the temperature of the lighting device near the temperature detecting means 550 in STEP2, then compared with a preset temperature range by the air conditioning apparatus operation control means 513 or blower operation control unit 543 based on the temperature detected by STEP3 If the temperature is within the set temperature range in STEP 4, the illumination input control means 503 reduces the illumination input and darkens the brightness to a level that does not cause a problem.

Here, the preset temperature range of the light flux change rate does not become extremely poor in accordance with the fluorescent lamp to be used from the view of the relationship between the ambient temperature and the rate of change in luminous flux of the illumination shown in FIG. 8 (e.g. 3 - 5 In the range where the rate of change in luminous flux decreases by about%). This set temperature zone may be set for each installation location within a range that does not feel dark depending on the environment such as the place of use and the time of use. If the temperature in the vicinity of the lighting device is within this set temperature range, for example, illumination input is performed until the light flux change rate reaches the lowest set temperature (temperature at which the light flux change rate does not feel dark). Reduce energy consumption for energy saving operation.

  The air temperature or ceiling temperature in the vicinity of the illumination is detected by the temperature detection means 550 in STEP 2, and the temperature detected by the temperature detection means 550 in STEP 3 is a temperature preset by the air conditioner operation control means 513 or the blower operation control means 543. Compare if in range. If it is within the set range, as described above, the illumination input is reduced at STEP 4 and the brightness of the illumination device is changed at STEP 5 to perform the energy saving operation. If it is outside the set range, the air conditioner operation control is performed at STEP 6. The means 513 or the blower operation control means 543 turns on the air conditioner operation or the blower operation. Then, in STEP 7, a part of the wind direction of the air blown from the air conditioner 511 is directed to the direction of the lighting device as indicated by 570 in FIG. 7, so that the temperature in the vicinity of the lighting device enters a preset temperature range. Control the air volume, temperature and so on. In order to change part of the air blowing direction of the air conditioner, a plurality of wind direction control plates provided at the air blowing port can be used and each can be variably controlled. It can be done by changing.

  The effect of improving the temperature inside the store 1 by the blower 533 is as described in the second embodiment, and as shown in FIG. However, the temperature difference of 10 ° C or more decreased to 21 ° C at a height of 2.5 m from the floor 3 minutes after the operation of the blower, and improved to a temperature difference of 1 ° C above and below the store. Therefore, when the temperature in the vicinity of the lighting device is out of the set range, the temperature in the vicinity of the lighting device is improved by operating the air conditioner 511 or the blower 533 in STEP 6. For example, the fluorescent lamp B in FIG. 8 is used. Thus, it can be used in a state where the luminous flux change rate is almost 100%, and STEP 4 represents that the illumination input can be reduced.

  Further, the step of comparing whether or not the temperature detected by STEP3 is within the set temperature range is omitted, and instead of STEP3, the relationship between the ambient temperature and the luminous flux change rate shown in FIG. Temperature input storage means for storing both the relationship between the luminous flux change rate and the input value for obtaining the required brightness, and calculating the optimum illumination device input based on the temperature information detected in STEP 2. By doing so, based on the temperature detected by the temperature detection means 550 in STEP2, the optimum input value is calculated by the temperature input storage means in STEP33 and notified to the illumination input control means 503, and the temperature input storage is made in STEP4. Based on information from the means, the illumination input control means 503 can change the input to the illumination device 500.

  Therefore, based on the temperature detected by the temperature detecting means 550 in STEP2, the optimum input value of the lighting device is calculated in STEP33, the input of the lighting device 500 is changed by the lighting input control means 503 in STEP4, and the lighting in STEP5. The brightness of the device can be changed, so that the optimal brightness of the lighting device does not feel dark even when the lighting device is installed not only indoors but also outdoors (outdoors) where the temperature improvement effect by the air conditioner or blower cannot be obtained. Thus, a low-cost and energy-saving lighting device that does not require useless input can be obtained.

  FIG. 14 is a diagram illustrating the principle of initial illumination correction of the lighting device. In the figure, the horizontal axis represents the cumulative time of lighting since the lighting device was installed, and the vertical axis represents illuminance. The lighting device has a preset design illuminance (illuminance at which sufficient brightness can be obtained). In the case of this figure, when the design illuminance is 70%, the relationship between the cumulative lighting time and the illuminance since the first lighting. It represents. From the figure, the illuminating device is installed and is too bright in the initial stage after the appropriate illuminance (70%) (the shaded area in the figure is wasted brightness) and is using wasted power. I understand.

  Accordingly, an illuminance detection means (not shown) is provided in the store 1 to measure the illuminance, and the illumination input control means 503 of the illumination device 500 adjusts the brightness by reducing the input based on the measured illuminance. By doing so, it is not necessary to consume wasted power due to the wasted brightness at the initial stage. In addition, the illumination input may always be adjusted in comparison with the illuminance from the illuminance detection means, but the illumination time is accumulated by a timer built in the microcomputer of the illumination input control means 503, and the illumination time in FIG. By having the illuminance relationship in advance as control data in the illumination input control means 503, it is possible to adjust the brightness by changing the illumination input according to the lighting time without the illuminance detection means. If it does so, in addition to the cost increase which provides an illumination intensity detection means separately, the effort which installs in the shop 1 can be saved.

  In addition, the illumination input reduction control by the initial illuminance correction is combined with the control for reducing the input of the illumination device by the illumination input control unit 513 based on the temperature in the vicinity of the illumination device detected by the temperature detection unit 550 described above. Thus, further input reduction can be performed, and further energy saving effect can be obtained. That is, in STEP 33, the optimum input value and the optimum input value may be calculated from the temperature input storage means based on the lighting time.

  Next, a method for supplying power to the lighting device 500 will be described. In stores 1 such as convenience stores, low-voltage power contracts (20 kW) such as air conditioner power supplies, refrigeration / refrigeration equipment (including showcase) power supplies connected to power distribution boards, and distribution boards for light systems Contracted with two power systems (25KVA), such as connected sales floor lighting power supply, signboard / parking lot lighting power supply, store signage power supply, heat insulation case power supply, and other lighting power supplies. There are many cases. Conventionally, even if there is surplus power in one system, it is not possible to switch to the other system or to switch to the other system when the supply of power to one system stops, etc. A method of switching and using power to another system when there is surplus power in the power of the different system at 17 or when the supply of power of the different system is stopped will be described.

  FIG. 16 is a diagram illustrating a method for switching power to the lighting device 500, and FIG. 17 is a diagram illustrating a method for switching power when a battery is used as a power supply source. In FIG. 16, 801 is a 200V three-phase power supply, 802 is a 200V single-phase power supply, 500 is a lighting device installed in the store 1, 811 is an air conditioner connected to the three-phase power supply 801, and 812 is a single-phase power supply. An electric device connected to 802, a system switching control circuit 820 for controlling switching between the three-phase power source 801 and the single-phase power source 802, and a power source switching circuit 825 having switch circuits 831 to 842.

  The system switching control circuit 820 is provided on a distribution board or the like, and includes power consumption detection means for detecting the power consumption of each power system (in this embodiment, two systems of the three-phase power source 801 and the single-phase power source 802), Whether the power consumption detected by the metered-price storage means and the power consumption detection means for storing the contracted power amount by power system, hourly, and season is exceeded the contracted power amount by referring to the metered-price storage means And marginal power calculation means that determines which power system should be used by calculating the residual of contract power and power consumption and determining which power system is cheaper. Yes. When it is determined that the power consumption of the power system having the surplus power amount calculation means exceeds the contract power amount, the power source switching circuit 825 is switched to switch to a power system having a surplus power in the contract power amount for a device capable of switching power sources. Give instructions.

  The power supply switching circuit 825 switches the system by turning each switch circuit ON / OFF according to an instruction from the system switching control circuit 820. When it is better to use the three-phase power source 801, the switch circuits 837 to 842 are turned on and the switch circuits 831 to 836 are turned off. Conversely, when it is better to use the single-phase power source 802, the switch circuits 831 to 836 are turned on and the switch circuits 837 to 842 are turned off. Also, when the system switching control means 820 determines that the power of one system has been stopped, the system switching control means 820 issues an instruction to the power switching circuit 825, and the power switching circuit 825 is switched to the system that has not stopped. Switch the switch circuit to connect.

  Therefore, a system with a low power charge is selected for the power supply of the lighting apparatus 500, or a system is selected so as not to exceed the contract power, so that a low-cost lighting apparatus can be obtained in total. In addition, even when the power supply of one system is stopped, it can be supplied from another system, so that lighting can be secured even at night and work can be continued safely.

  In FIG. 17, 801 is a 200V three-phase power supply, 802 is a 200V single-phase power supply, 500 is a lighting device installed in the store 1, 811 is an air conditioner connected to the three-phase power supply 801, and 812 is a single-phase power supply. Electrical devices connected to 802, 851 and 859 are diodes and the like are rectifier circuits that convert alternating current into direct current, 852 and 858 are inverter circuits composed of switching elements, 854 are storage batteries, and 855 are charge / discharge circuits. Yes, energy storage in the storage battery 854 and energy release from the storage battery 854 are performed. The charge / discharge circuit 854 controls the DC bus voltage value so as to coincide with a target voltage suitable for charging the storage battery 854 while detecting the storage battery voltage. Reference numerals 856, 857, and 860 are switch circuits that switch the circuit to be energized by turning ON / OFF the contact of the connection line and energizing / disconnecting the connection line.

  The alternating current power supplied from the three-phase power source 801 is converted into direct current by the rectifier circuit 851, converted to a necessary voltage by the inverter circuit 852, and supplied to the air conditioner 811 and the like, and the single phase power source 802 is supplied to the electric equipment 812 as it is. The The lighting apparatus 500 includes a power system that is connected when each switch circuit of the power supply switching circuit 825 is turned on / off in accordance with an instruction of which power system of the system switching control circuit 820 described with reference to FIG. Determined. For example, when the three-phase power source 801 is used, the switch circuits 856 and 857 are turned on and the switch circuit 860 is turned off. When the single-phase power source 802 is used, the switch circuit 860 is turned on and the switch circuit 857 is turned off.

  Further, when the supply of electric power is stopped due to a power failure or the voltage of the supplied electric power is reduced, electric power is supplied from the storage battery 854. For example, when the power supply of both the three-phase power source 801 and the single-phase power source 802 is stopped or when the power supply of only the three-phase power source 801 is stopped, the system switching control circuit 820 turns on the switch circuits 856 and 857. , The switch circuit 860 is turned off, and the charge / discharge circuit 855 is instructed to release energy to the storage battery 854. The charge / discharge circuit 855 supplies power from the storage battery 854 to the air conditioner 811 and the lighting device 500. When the supply of power from the single-phase power source 802 is stopped, the system switching control circuit 820 releases the energy to the storage battery 854 to the charge / discharge circuit 855 by turning on the switch circuit 857 and turning off the switch circuits 856 and 860. Give instructions to do so. The charge / discharge circuit 855 supplies power to the lighting device 500 from the storage battery 854. In addition, the storage battery 854 is charged in a time zone in which a power charge such as midnight power is inexpensive.

  Therefore, by providing a storage battery, even if the supply voltage stops or cannot be used due to a drop in voltage, power can be supplied and a low-cost power system is used. High air conditioning and lighting system. In addition, the lighting input control unit 513 performs illumination based on the temperature in the vicinity of the lighting device detected by the temperature detection unit 550 in the arrangement method of the air conditioner and the refrigeration / freezing device described in the first embodiment or the second embodiment. Combining the control to reduce the input of the device, the initial illumination correction control of the lighting device explained in FIG. 14 and the power supply switching control explained in FIG. 16 and FIG. 17, further energy saving effect as a whole store can be obtained. A low-cost and energy-saving thermal equipment system or air conditioning / lighting system can be obtained.

  In this embodiment, the power supply of the 200V three-phase power supply 801 and the 200V single-phase power supply 802 has been described as an example. However, if the lighting device 500 is compatible with 100V and 200V, the power supply is 200V and 100V. However, the same effect can be obtained by switching the power source. In addition, although the power source switching for the lighting device 500 has been described in the present embodiment, it is not separately applied only to the lighting device, and is compatible with power supplies with different specifications (for example, both 100V and 200V). The same effect can be obtained. Further, a refrigeration / freezing device may be used instead of the air conditioner 811. Further, the system switching control circuit 820 and the power supply switching circuit 825 may be provided in the distribution board, or may be provided separately from each distribution board, or in the controller 200 described in the fourth embodiment. It may be provided.

  FIG. 13 is a diagram showing an operation control flowchart of the refrigeration / freezing apparatus and the air conditioner. In the figure, STEP 11 is the start, STEP 12 is a temperature detection step for detecting the temperature of the opening or the rear air passage where the food in the showcases 101, 102, 103 is cooled and stored, and STEP 13 is the cooling detected by the temperature detected at STEP 12 Step 14 is an air conditioner operation step in which the air conditioner is turned on and the air conditioner is operated in the cooling mode. STEP 15 is an airflow distribution of the air blower of the air conditioner. Step 16 is a step for changing the air region distribution, STEP 16 is a notification step for notifying the outside that cooling is insufficient, and STEP 17 is the air region distribution of the air blowing when the air conditioner is ON. Wind area distribution adjustment system to prevent it from reaching the opening Tsu is a flop.

  Usually, the temperature in the opening or the rear air passage is detected in STEP 12, and it is determined whether or not the cooling is insufficient in STEP 13. If it is determined that the cooling is not insufficient, the first embodiment or the first embodiment is determined in STEP 17. As described in 2, the air blowing direction is adjusted so that the air region distribution of the air blowing of the air conditioner does not reach the openings of the showcases 101, 102, and 103. However, when it is determined in STEP 13 that the cooling is insufficient, the power of the air conditioner is turned ON in STEP 14 to operate in the cooling mode to cool the store 1. Further, in STEP 15, the air blowing direction of the air conditioner is changed so that the air region distribution is applied to the openings of the showcases 101, 102, 103. In STEP 16, the outside of the store 1 (service center 375, mobile phone 374, etc.) is notified that the showcase is insufficiently cooled.

  One of the showcases 101, 102, or 103 is insufficiently cooled due to gas leakage or the like, and the control means 310 of the control board 300 (131, 132, 133 in FIG. 10) shown in FIG. In this case, the control means 310 outputs an identification signal indicating that cooling is insufficient to the air conditioner. This identification signal is placed on the power line via the communication interface 311 and reaches the controller 200. The microcomputer 372 of the controller 200 confirms the destination and contents, and outputs a signal to the air conditioner so as to operate in the cooling mode. The output signal reaches the control means 340 via the communication interface 341 of the control board 330 of the air conditioner. At STEP 14, the control means 340 turns on the air conditioner based on the signal that has arrived, and cools the store in the cooling mode. Further, the control means 340 changes the air blowing direction of the air conditioner in STEP 15 so that the air region distribution covers the openings of the showcases 101, 102, 103. The air blowing direction of the air conditioner can be changed by changing the direction of the wind direction control plate by variably controlling the wind direction control plate provided at the air blowing port.

  Therefore, even if the refrigeration / freezing device is undercooled, the room where the refrigeration / freezing device is installed is cooled, so heat that can prevent damage to food stored in the opening of the refrigeration / refrigeration device is suppressed. An equipment system is obtained. In addition, if the air blowing range of the air conditioner is changed so that it covers the opening of the refrigeration / freezing device, the air cooled by the air conditioner directly hits food stored in the opening of the refrigeration / refrigeration device. As compared with the case where the room is cooled without being applied to the inside, a thermal equipment system that can further suppress damage to foods and the like can be obtained.

  Further, the microcomputer 372 of the controller 200 outputs a signal to the external service center 375 and the mobile phone 374. The output signal reaches the telephone station 373 via a modem 371 by communication means such as a telephone line, radio or satellite, and the service center 375 and the mobile phone 374 are notified that the showcase is insufficiently cooled.

  The notified service center 375 immediately monitors the operating state of the showcases 101, 102, 103, confirms contact with the customer, stops the operation of the showcase, or installs a showcase with insufficient cooling. Implement services such as business trips to stores. Therefore, when it is determined that the cooling is insufficient, the service center 375 can immediately receive the service, so that the influence on the food stored in the openings in the showcases 101, 102, 103 can be minimized, and the service is further improved. Until the service person of the center 375 arrives, the inside of the store is cooled and cooled, so that the influence on the food stored in each opening is further reduced even in the case of nobody at night or on holidays. Highly reliable thermal equipment system. In addition, since an existing power line is used as a communication means, no special wiring is required and the cost can be reduced.

  In addition, since the service center 375 is notified and the mobile phone 374 is also notified, abnormalities in the showcases 101, 102, 103 can be confirmed even when away from home, and it is possible to respond immediately. Further, the service center 375 or the cellular phone 374 displays the operating states of the showcases 101, 102, 103 and the air conditioner 121 (for example, whether the compressor is operating or the set temperature and the current temperature are several times) If the operation state of the showcases 101, 102, 103 and the air conditioner 121 can be controlled from the center 375 or the mobile phone 374 (showcase or ON / OFF of the air conditioner, set temperature, change of air volume, etc.) The showcase can be stopped from the service center 375 or the mobile phone 374 in the case of an abnormality such as a shortage, and the air conditioner can be turned on, minimizing food damage in the opening of the showcase while on the go It becomes possible to suppress to.

  Furthermore, in order to judge whether the temperature detection means 141, 142, 143 is malfunctioning, it is operated for a while and the temperature detection means 141, 142, 143 is checked by changing the temperature or changing the set temperature. Can do. Therefore, it is possible to control the operation of the showcase and air conditioner after confirmation (stopping the operation of the showcase and starting the operation of the air conditioner, etc.) and preventing damage to food stored in the opening due to the stop of the showcase due to malfunction And no need to go to useless services.

  In addition, when multiple showcases are installed, one showcase can be cooled by connecting the inside of the opening of the showcase and the opening of another showcase via a solenoid valve or the like by piping or ducts. In the event of a shortage, the chilled air in the opening of another showcase can be sent into the opening of the showcase that is undercooled by opening the solenoid valve. Therefore, when it is determined that the showcase is insufficiently cooled, if the solenoid valve of the pipe or duct connected to the showcase determined to be insufficiently cooled is opened, the serviceman of the service center 375 can arrive until the serviceman arrives. Because the inside of the opening of the showcase that is determined to be insufficiently cooled is cooled by a normal showcase that is not insufficiently cooled, the effect on food stored in the opening is even smaller even at night and on holidays, especially in the case of unmanned A highly reliable thermal equipment system can be obtained.

  The showcase is always connected to the power line, and is always cooled so that food in the opening is not damaged. If the showcase breaks down and the cooling is insufficient, the food in the opening will be damaged. . Therefore, as in the present embodiment, the operation status of the showcase is confirmed from the outside of the store where the showcase is installed (particularly, a place where the showcase is installed), so as to respond immediately when a showcase malfunctions. Thus, even when the showcase is abnormal, damage to food in the showcase can be minimized, and a highly reliable thermal equipment system can be obtained.

  Furthermore, if the lighting devices 221 to 226 and the control boards 211, 212, and 213 of the air outlets 201, 202, and 203 of the air conditioner are connected by the lamp lines 271 to 279 as shown in FIG. There is no need to provide it, and a network can be assembled at a low cost. Further, the control means provided on the control boards 211, 222, and 223 for the air conditioning measures based on the temperatures detected by the temperature detection means 251 to 256 installed in the vicinity of the lighting devices 221 to 226 described in the third embodiment. If it is within the set range compared with the temperature range set in advance at 310, a signal is transmitted to the lighting device via the controller 200 using the power line as the communication means, and the lighting devices 221 to 221 are based on the transmitted information. The control means 360 of the control boards 231 to 236 of 226 can reduce the input of the illumination, and the energy saving operation can be performed by reducing the brightness to a level that does not cause a problem. Therefore, the air conditioner control means controls the operation of the air conditioner in order to improve the temperature in the vicinity of the illumination apparatus based on the temperature information from the temperature detection means. An efficient air conditioning and lighting system that can be used is obtained.

  Further, the air temperature or ceiling temperature in the vicinity of the lighting device is detected by the temperature detection means 251 to 256, and the temperature detected by the temperature detection means 251 to 256 is detected by the control means 340 of the control boards 211, 212, and 213 of the air conditioner. Compare if it is within the preset temperature range. If it is within the set range, the lighting input is reduced and the energy saving operation is performed as described above. However, if it is outside the set range, the control means 340 of the control board of the air conditioner turns on the air conditioner (or the blower). Set the operation to ON). Then, by directing at least part of the wind direction from the air outlets 201, 202, 203 of the air conditioner toward the direction of the lighting device, the air volume, temperature, etc., so that the temperature in the vicinity of the lighting device falls within a preset temperature range. To control.

  Further, if the temperature detecting means for detecting the temperature in the vicinity of the lighting device described in the third embodiment is incorporated in the lighting device or provided in the casing of the lighting device, it is necessary and necessary to separately provide the temperature detecting means. Therefore, an illumination system that can reduce the installation time at a low cost can be obtained. Also, if the air inlet of the air conditioner is installed at approximately the same height as the lighting device in the store, the temperature detection in the vicinity of the lighting device can be used as the suction temperature detection means of the existing air conditioner. If replaced, there is no need to provide and attach a separate temperature detecting means, and an air conditioning / illumination system capable of reducing the installation time at a low cost can be obtained.

  Further, when the operation of the air conditioner (or blower) is started, the upper and lower temperature distribution in the store 1 is improved and the temperature distribution in the vicinity of the lighting device is also improved as described above. If the input of the lighting devices 221 to 226 is controlled to be reduced to the extent that the input of the lighting devices 221 to 226 is not darkened by the means 503, it is not necessary to use the temperature detection means 251 to 256. Is obtained.

  In addition, the control of directing at least a part of the direction of the wind from the air outlet of the air conditioner toward the direction of the illumination device as described above is reduced (or wireless, telephone line, If the network is configured by a satellite line or the like, it can be changed from the service center 375 outside the store 1, the mobile phone 374, or the like. For example, if the lighting input in the store 1 is reduced and it is not desired to control the energy saving operation by changing the brightness to such an extent that it does not feel dark, it can be changed from the mobile phone 374 or the like. Even if you are not at the store, you can change from wherever you are, and there is no need to return to the store 1 just to change. Furthermore, if it is possible to control from the outside the initial correction of the lighting device described in Embodiment 3, the switching of the power supply of the lighting device, and the use of a storage battery for the power source, the current power supply used while on the go It is possible to grasp the situation, the charging status of the storage battery, etc., and to change the instruction to change the power source or use the storage battery.

  In the case of troubles other than insufficient cooling of the showcase (for example, air conditioner abnormalities (such as abnormalities in pressure, temperature, mode switching, etc.), lighting apparatus abnormalities (such as abnormal illuminance), electric leakage, etc.) Reliability is further improved and products that can be used with peace of mind can be provided. In addition, if the lighting input control means or the air conditioner operation control means is controlled from the outside (service center, mobile phone, etc.), the air conditioner / lighting system with high reliability can be controlled while on the go. Is obtained. In the present embodiment, the power line is used as the communication means, but the same effect can be obtained by the Internet, e-mail, wireless communication, infrared communication, satellite communication using the existing telephone line or ISDN line.

  When wireless communication (or infrared communication) is used as a communication means, if the communication interface 380 for wireless communication (or infrared communication) is installed in the controller 200, wireless communication (or infrared communication) and power line communication are used together. Even so, it is determined to which device each communication interface is a message, and the service center 375 and the mobile phone 374 are notified. Conversely, even when an instruction is issued from the service center 375 or the mobile phone 374, the instruction content is transmitted to each device by the microcomputer 372 and the communication interfaces 370 and 380 in the controller 200.

  In addition, a monitor made of liquid crystal or the like can be mounted on the controller 200 to display the operation state of each device, and to change or control the operation state of each device by operating the monitor. In this embodiment, the controller 200 is installed indoors or outdoors separately from the air conditioner, the refrigeration / freezing device, and the lighting device. However, it is not necessary to separately provide the controller 200, and the air conditioning device, the refrigeration / freezing device, or the lighting device. If it is provided in the distribution board together with the system control switching circuit 820 and the power supply switching circuit 825 described in Embodiment 3, a network system can be constructed at a lower cost than that provided separately.

Embodiment 5 FIG.
In the fifth embodiment, a case will be described in which each device in the store is centrally controlled from a management room or the like.

In the figure, reference numeral 601 denotes a control unit of the air conditioner, and information from the air conditioner sensor (at least the store temperature detected by the store temperature sensor, the store humidity detected by the store humidity sensor, and the outside temperature detected by the store temperature sensor). , The outside air humidity detected by the outside air humidity sensor), the in-store temperature target value, the in-store humidity target value, and the identification signal of the air conditioner operation mode (cooling, heating, dehumidification, etc.) are transmitted to the controller 700 via the communication interface 611. In addition, it receives information and control content from the controller 700 and performs operation ON / OFF control, operation mode switching control, and the like.

  Reference numeral 603 denotes a ventilator control means that provides information from a ventilation fan sensor (at least the outside air temperature detected by the outside air temperature sensor and the outside air humidity detected by the outside air humidity sensor) and the ventilation fan operation mode (ON / OFF, rotation). (Number, air volume, etc.) identification signals are transmitted to the controller 700 via the communication interface 613, and information and control contents from the controller 700 are received to perform operation ON / OFF control and operation mode switching control.

  The control means 700 of the controller stores information from the air conditioner sensor, information from the ventilation fan sensor, data such as a target value and an operation mode as device correlation physical quantities. Based on these equipment correlation physical quantity data, the outside air intake air volume is determined by a preset outside air intake operation algorithm so that the enthalpy difference to the target temperature and humidity point is small and the load to be cooled and dehumidified is small. A control signal for changing the opening degree or the rotation speed of the ventilator so as to obtain the determined appropriate air volume is transmitted to the ventilator control means 603 via the communication interface 613, and the ventilator control means 603 Change the opening of the outside air intake passage and the rotation speed.

  Further, the control unit 601 of the air conditioner uses an in-store upper temperature information from the air conditioner sensor (at least the in-store upper temperature detected by the in-store upper temperature sensor installed in the upper part of the store or the intake air temperature sensor of the indoor unit of the air conditioner). An identification signal of the detected intake air temperature) is also transmitted to the controller 700 via the communication interface 611. Reference numeral 602 denotes a control unit for the refrigeration / freezing device, which includes in-store lower temperature information from the refrigeration / freezer device sensors provided in the refrigeration / freezer showcases 101, 102, 103 (condensation sensor or in-store lower temperature detection sensor provided separately) The temperature detected by the temperature sensor provided in the indoor remote controller of the air conditioner is transmitted to the controller 700 via the communication interface 612, or receives information and control content from the controller 700 for operation. ON / OFF control and operation mode switching control are performed.

  The controller control means 700 stores in-store upper part temperature information from the air conditioner sensor and in-store lower part temperature information from the refrigeration / refrigeration unit sensor as equipment correlation physical quantities. If the difference between the store upper temperature and the store lower temperature is greater than or equal to the preset value based on the preset store upper / lower temperature improvement operation algorithm based on these device correlation physical quantity data, the air conditioner starts operating. Control information such as the operation mode or the start of operation of the blower or the operation mode is transmitted to the control unit 601 of the air conditioner and the control unit 604 of the blower via the communication interfaces 611 and 614. The control unit 601 of the air conditioner performs operation ON of the air conditioner and changes of the operation mode (cooling, heating, dehumidification, etc.) based on the received control information, and the control unit 604 of the air blower is based on the received control information. Turn on or change the number of revolutions. As a result, as described in the first or second embodiment, the temperature distribution in the upper and lower portions of the store is improved.

  Reference numeral 605 denotes a control unit for the indoor lighting device, which transmits a signal of indoor illuminance information from the indoor illuminance sensor to the controller 700 via the communication interface 615, or receives information and control content from the controller 700 and inputs illumination. Perform dimming control to change and adjust brightness. Reference numeral 606 denotes a control unit of the outdoor lighting device, which transmits a signal of outdoor illuminance information from the outdoor illuminance sensor to the controller 700 via the communication interface 616, or receives information and control content from the controller 700 and inputs the illumination input. Perform dimming control to change and adjust brightness.

  The controller 700 stores the indoor illuminance information from the indoor illuminance sensor and the outdoor illuminance information from the outdoor illuminance sensor together with information such as date / time, sunrise time, sunset time, and weather forecast (sunny, rain, etc.) as device correlation physical quantities. To do. Then, based on the data of the device correlation physical quantity, the initial illumination correction control, the daylight use control, and the lighting / extinguishing time control are performed by a lighting device control operation algorithm set in advance. The information is transmitted to the controller 605 of the indoor lighting device and the controller 606 of the outdoor lighting device via 616.

  In the initial illumination correction control, the lighting device described in FIG. 14 in the third embodiment is too bright at the initial stage of installation, so that the input is reduced and the initial illumination is reduced, thereby eliminating unnecessary brightness and reducing the input energy. To get. In addition, daylight usage control is to reduce energy input by reducing lighting input and reducing illuminance in the store when the daytime is sunny and the outdoors is brighter than a certain level, thereby eliminating the useless brightness and obtaining an energy saving effect by reducing input. . In addition, the lighting / lighting-out time control can be done without manpower by controlling the lighting / lighting-off time of the outdoor lighting device using an illuminance control timer, etc., based on the relationship between the date of the day and the brightness outside the store. The outdoor lighting device is automatically turned on / off.

  Based on the received control content, the control means 605 for the indoor lighting device and the control means 606 for the outdoor lighting device perform initial illuminance correction control, daylight use control, and lighting / extinguishing time control, thereby saving energy.

  In addition, an air conditioner power consumption sensor that measures the power consumption of the air conditioner on the distribution board that supplies power to the air conditioner, and a refrigerator / refrigerator such as a showcase or refrigerator on the distribution board that supplies power to the refrigerator or freezer.

Information on the power consumption is transmitted to the respective control means 601, 602, 605, 606 by means of communication means such as a power line, wireless or infrared. Each control means 601, 602, 605, 606 that has received the power consumption information transmits information from each power consumption sensor to the control means 700 of the controller via a communication means such as a power line, wireless, or infrared.

The controller control means 700 uses the power consumption reduction algorithm to set the target temperature setting value and humidity setting value in the store so that the sum of the power consumption of the air conditioner, the power consumption of the refrigeration / freezing device, and the power consumption of the lighting device is minimized. A change instruction is issued to the control unit 601 of the air conditioner via the communication interface 611 by a communication unit such as a power line, wireless, or infrared. Further, when the controller's control means 700 is likely to exceed a preset target input value, the brightness in the store or outdoors is reduced to an input value corresponding to a preset brightness that does not feel dark. Then, a priority is given to the lighting device control means 605 and 606 via the communication interfaces 615 and 616.

  Further, when changing the target set temperature and target set humidity according to an instruction from the controller control means 700, when the target input is likely to be exceeded, or when changing the illumination input to change the brightness, the controller control means 700 is transmitted to the management room 750 that performs centralized control via the modem 371, the telephone station 373, and the modem 372. The management room 750 can also issue a change cancellation instruction so as not to change when it is difficult to change, and can cancel the change.

  Therefore, the power consumption of the entire store can be grasped, and the indoor temperature and humidity, the brightness of the indoor lighting, and the brightness of the outdoor lighting are adjusted and changed so that the power consumption is minimized. Consumption can be reduced and a low-cost power consumption reduction system can be obtained. In addition, if communication means such as a telephone line, power line, or radio is notified to an outdoor service center or mobile phone or the air conditioner operation control means and lighting control means are controlled from outside the room, the power consumption of the entire room is immediately It is possible to obtain an air conditioning / lighting device that can grasp the amount and adjust and change the usage state of each device so that the entire input value does not exceed the target value even when the user is away from home.

  The controller control means 700 also sends information such as the operation state of each device, information on various sensors, and operation modes as described above to the management room 750 that performs centralized control via the modem 371, the telephone station 373, and the modem 372. Send. The management room 750 can be changed at any time when it is considered that it is not desired to operate according to the operation algorithm described above based on the operation state of each device, information on various sensors and operation modes. Further, each operation algorithm may be implemented individually or in combination. Further, as described in the fourth embodiment, if information is also transmitted to an external mobile phone or the like, it is possible to grasp the operating state of each device while on the go and to control and change the operation. In addition, the power line, the wireless, and the infrared light described in the fourth embodiment are connected to the communication unit that connects the control units 601 to 606 and the communication interfaces 611 to 616, or the communication unit that connects the communication interfaces 611 to 616 and the controller 700, respectively.
