Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning system, and more particularly to, for example, a Predicted Mean Vote (PM).
V) The present invention relates to an air conditioning system for individually air-conditioning a plurality of zones based on V).

[0002]

2. Description of the Related Art Conventionally, Fan of the Technical University of Denmark
There are attempts to control air conditioning with PMV that can be calculated by the PMV equation proposed by ger. As one of them, a method of controlling a fan coil unit (FCU), an air conditioner or an air handling unit (AHU) based on a comfort level (PMV) detected by a comfort sensor has been proposed. As such a comfort sensor, there is “TY4700” manufactured by Yamatake Honeywell Co., Ltd.

[0003] The PMV is obtained, for example, as a value from -3 to +3. If the air-conditioning control is performed so that the value becomes "0", it is possible to prevent the temperature from being too hot or too cold. That is easy to predict.

[0004]

However, the conventional comfort sensor is an independent device such as a wall-mounted type or a desktop type, and has its own room temperature, relative humidity, radiation (radiation) temperature, and airflow velocity. It is very expensive because of the provision of a sensor for detecting the load and a setting device for setting the parameters of the amount of activity and the amount of clothing. Also, since the prior art is an independent device, it is not clear how to incorporate it into the air conditioning system.

[0005] Therefore, a main object of the present invention is to provide an air conditioning system which can be controlled at a lower cost based on PMV.

[0006]

[0007]

The air conditioning system is constructed using a VAV unit or a fan coil unit. When VAV units are used, an air conditioner that supplies conditioned air to each VAV unit is provided. When fan coil units are used, each fan coil unit is provided with a heat exchanger.

[0008] In any case, the comfort level calculating means fetches the data of the room temperature and the radiant temperature in the corresponding zone from the room temperature sensor and the radiant temperature sensor of the relevant room controller, and also through appropriate communication means. The data of the humidity from the humidity detecting means and the data of the parameter from the parameter setting means are taken in. Then, the comfort level (PMV) is calculated by the Fanger PMV equation (or a simplified or modified version thereof).

[0009] In the VAV system, the calculated PMV is used for controlling the VAV unit. For example, in the case of an air conditioning system in which the user sets a desired temperature in the indoor controller, the required airflow is determined based on the PMV correction value and the PMV value. In a system in which the air flow of the VAV unit is directly controlled by the PMV without setting the desired temperature, the required air flow may be determined based on the PMV.

When the fan coil unit is used, the control means controls the amount of air blown from the fan coil unit and the supply air temperature in accordance with the calculated PMV.

[0011]

According to the present invention, the indoor temperature detecting means and the radiant temperature detecting means which need to accurately grasp the state of each zone are provided in association with each indoor controller, and other relative humidity detecting means and parameters are provided. Since the setting means is provided separately, the cost can be reduced as compared with the case where an independent comfort sensor is used as in the related art.

Further, the VAV unit and the fan coil unit can be controlled based on the comfort level or the PMV obtained by the comfort level calculation means, and a more comfortable air conditioning system can be realized. The above object of the present invention,
Other objects, features and advantages will become more apparent from the following detailed description of embodiments, which proceeds with reference to the accompanying drawings.

As the temperature sensor 68 and the radiation temperature sensor 70, for example, both “103AT-2” and “radiant heat sensor” manufactured by Ishizuka Electronics Co., Ltd.
Is available.

The liquid crystal display 72 of the indoor controller 66 displays various states in a visible manner.
An MV display section 74 is included. The PMV display section 74 displays the PMV in “high / low”. When the PMV correction switch 76 is pressed, the PMV display 74 displays the PM in the “high” direction.

As shown in FIG.
Includes a CPU 82. The CPU 82 captures data of the room temperature and the radiation temperature from the temperature sensor 68 and the radiation temperature sensor 70 through the A / D converter. CP
The switches 76 and 78 described above are connected to the parallel IO of U82.
And 80 are connected, and the CPU 82
The state of 80 is taken. The LCD driver of the CPU 82 drives the liquid crystal display 72, and the liquid crystal display 72 displays the temperature and the PMV. A communication driver 84 is connected to the serial IO of the CPU 82. The CPU 82 receives data or signals from the repeater 86 (FIG. 1), that is, data or signals from the air conditioner controller 16 via the communication driver 84. Or the repeater 86, ie, the air conditioner controller 16 and the VAV controller 6
4 to send data or signals. Specifically, the data is transmitted by a power supply line of the power supply unit 88.

In this embodiment, each VAV controller 6
4 and an SI (Sial Interface) terminal 90 of the air conditioner controller 16 are connected via a communication cable 92a, a terminal board 94 and a communication cable 92b, and the indoor controller 66 and the SI (Sial Interface) terminal 90 are connected to a communication cable 92c, The VAV controller 64 and the indoor controller 66 are connected via a terminal board 94 and a communication cable 92b.
4 and the communication cable 92c.

As shown in FIG. 4, the terminal board 94 constituting a part of such communication means includes a terminal block 98 having a plurality of terminals 96 and a repeater 86. The repeater 86 includes, as shown in FIG.
2, switch 104 and power line superimposed transceiver 106
, And each of the communication cables 92 a and 92 b is connected to the transceiver 102, and the cable 92 c extending from the indoor controller 66 is connected to each power line superimposed transceiver 106.

A communication cable 92c from the indoor controller 66 to the terminal block 98 is wired using a telephone line such as a 4-core telephone line 108 or a 2-core telephone line 110 as shown in FIG. That is, when using the 4-core telephone line 108, two out of the four core lines 108a to 108d are used.
Two core wires 108a and 108b are connected to the communication cable 92c.
These are connected to the repeater 86 via the terminals 96 of the terminal block 98. And the other two core wires 1
08c and 108d are used as telephone lines 114 of telephone 112, which are connected via terminal 96 to telephone exchange 1
16 is connected. On the other hand, when the two-core telephone line 110 is used, the two cores 110a and 110b are used as the communication cable 92c, and these are connected to the repeater 86 via the terminal 96. However, 2 of the 2-core telephone line 110
When the two core wires 110a and 110b are connected to the telephone exchange 116 via the terminal 96, the two-core telephone line 110 can be used as it is as a telephone line for the telephone 112. Therefore, if a plurality of two-core telephone lines 110 are wired in advance, any one or two or more two-core telephone lines 11
0 for the telephone 112 and the rest for the indoor controller 66.
Can be used.

However, it goes without saying that other types of communication means may be used in addition to the above-mentioned telephone line. The general operation of such an air conditioning system 10 is as follows. That is, when the on / off switch 80 of the indoor controller 66 is turned on, the ON signal is transmitted from the indoor controller 66 through the communication driver 84, the communication cable 92c, the terminal 96, the repeater 86, and the communication cable 92a.
8 given. As a result, when the air conditioner 18 is turned on and the heating operation mode is selected, the cooling coil 3
The electric valve of the heating coil 32 is opened, and the electromagnetic valve of the humidifier 34 is opened as necessary. Then, the air supply fan 36 is driven at a predetermined rotation speed so as to satisfy the required air volume required in the entire room 12. Then, the outside air and the return air sucked by the air supply fan 36 are taken into the housing 20 through the outside air port 24 and the return air port 26. Then, the air (outside air and return air) is dust-removed through an air filter 28, heated through a heating coil 32, and humidified as necessary through a humidifier 34, and then supplied through an air supply duct 56 by an air supply fan 36. Air is supplied from the air supply port 54 to each of the zones 14 a to 14 e in the room 12.

In communication of each data or signal, the destination of the data or signal is determined by each component (equipment).
Of the terminal board 94 in accordance with the address assigned to
(Such as the microcomputer 100 and the switch 104). On the other hand, when the cooling operation mode is selected,
The electric valve of the cooling coil 30 is opened, and the electric valve of the heating coil 32 and the electromagnetic valve of the humidifier 34 are closed. Then, the air supply fan 36 is rotated at a predetermined rotation speed. Then, the air (outside air or return air) taken into the housing 20 from the outside air port 24 or the return air port 26 is dust-removed through the air filter 28, cooled through the cooling coil 32, and then supplied to the air supply duct by the air supply fan 36. The air is supplied from each air supply port 54 to each of the zones 14 a to 14 e in the room 12 through 56.

In any case, the amount of air supplied from each air supply port 56 is determined by the PMV provided from the corresponding indoor controller 66 via the communication cable 92c, the terminal 96, the repeater 86, and the cable 92b, or the PMV supplied thereto. Each VAV unit is controlled by the VAV controller 64, that is, the VAV unit 62 based on the correlated data.

Here, prior to the description of the air conditioning control based on the PMV, a method for obtaining the PMV will be described. Fa

_Equation 21 is for “I _cl <0.5 · CLO”, and Equation 22 is for “I _cl ≧ 0.5 · CLO”. In the above-described embodiment, the airflow velocity v of Expression 20 is obtained as a function of the actual air volume (Q) in the VAV unit 62 and the number of ventilations. That is, the airflow velocity v can be obtained as v = αQ. Here, α is a proportional constant determined by parameters such as the number of ventilations. Therefore, since the VAV controller 64 can know the air volume (Q), if the air volume data is given to each indoor controller 66 by using the communication means described above, the air flow velocity can be easily obtained by the indoor controller 66. v can be obtained.

Note that the air volume (Q) is VAV unit 6

Furthermore, if the airflow velocity v is less than 0.1 m / s, the PMV
Since it hardly affects the value, a fixed value which is a representative speed may be set as the airflow speed.

Further, “CLO” in Expressions 21 and 22 is used.
Is set by the clothing amount setting device 118 in FIG. Then, “AL” in Expression 24 is set by the activity amount setting unit 120 in FIG. Further, the central temperature setting device 122 shown in FIG.
Set an initial temperature value such as These setting devices 11
Each of 8, 120 and 122 is constituted by a variable resistor or a potentiometer, and is connected to the AI terminal 44 of the air conditioner controller 16. Therefore,
Each set value is input to the air conditioner controller 16 as an analog value, and the air conditioner controller 16 converts the analog value into a digital value (data) and gives it to the indoor controller 66 through communication means.

The operation of the indoor controller 66 will now be described with reference to FIG. In step S1 of FIG. 6, the CPU 82 of the indoor controller 66 reads room temperature data from the temperature sensor 68. In step S3, the CP
U82 reads the radiation temperature data from the radiation temperature sensor 70. Then, in step S5, the air conditioner controller 16, the VAV controller 64, and the repeater 86 (FIG. 1)

The air velocity v is read. Then, in step S7, the CPU 82 calculates the PMV according to Equations 17 to 25 described above.

In the next step S9, the CPU 82
Determines whether the calculated PMV falls within the range of “−1” to “+1”. PMV is basically
It is calculated as a value in the range of “−3 to +3”. That is, as shown in Table 1.

[0066]

The CPU 82 reads the states of the PMV correction switches 76 and 78 from the parallel IO. PMV correction switch 7
When 6 is pressed, the user performs an operation of correcting the PMV in a direction to increase the PMV. When the PMV correction switch 78 is pressed, the user performs an operation to correct the PMV in a direction to decrease the PMV.
Therefore, the CPU 82 determines in step S19 that P
It is determined whether the MV needs to be corrected. When the correction is necessary, that is, when the PMV correction switch 76 or 78 is operated, the PMV is calculated again in step S7, and each step after step S9 is executed. This P
When changing or correcting the MV, the PMV
MV is displayed.

When the PMV correction has been completed or no correction is necessary, the CPU 82 proceeds to step S11 or S1.
According to the set temperature (T _S ) obtained in 3, the required air volume (Q)
Is calculated. Since the calculation of the required air volume is well known in an air conditioning system using a VAV unit, a detailed description is omitted here. The data of the required air volume (Q) thus obtained is transmitted to the VAV controller 64 via the repeater 86. Depending on,
The VAV controller 64 adjusts the opening of the damper 60 of the VAV unit 62 based on the difference between the current air volume and the required air volume, for example, as shown in FIG. However, when the air volume cannot be satisfied only by controlling the damper opening, the air conditioner controller 16 controls the air blowing function power and the temperature of the air conditioner 18 as a matter of course.

In the embodiment shown in FIG. 6, the set temperature (T _S ) is changed based on the PMV, and thereby the VAV unit 62 is controlled. However, as in the embodiment shown in FIG. 8, the VAV unit 62 may be directly controlled by the PMV. Steps S1 'to S7' of the embodiment of FIG. 8 are the same as steps S1 to S7 of FIG. Then, after calculating the PMV in step S7 'of FIG.
17 'and S19', and the CPU 82
It is determined whether or not correction is necessary. If correction is needed,
Step S7 'is executed again, and if no correction is necessary, step S21' is executed. In step S21 ',
In the previous embodiment, the air volume was determined from the set temperature,
The air volume is obtained directly from the MV. That is, as shown in FIG. 9, instead of the set temperature of FIG. 7, the required airflow is determined according to the PMV with the horizontal axis representing the PMV. Then, step S23 'similar to step S23 in FIG. 6 is executed.
Therefore, the VAV controller 64 controls the VAV unit 62, that is, the damper 60 according to the PMV.

In the above-described embodiment, the control based on the PMV value is incorporated in the air conditioning system using the VAV unit. However, the air conditioning system using the fan coil unit can of course perform the PMV control. . FIG. 10 is an illustrative view showing an air conditioning system using a fan coil unit according to another embodiment of the present invention. The FIG. 10 embodiment differs from the FIG. 1 embodiment in the following points. Therefore, in FIG. 10 (and FIG. 11), the same or similar reference numerals are given to the same or similar parts as in FIG. 1, and the detailed description thereof will be omitted.

The air conditioning controller 126 includes an inverter circuit 130 for controlling the motor of the blower fan 128 of the corresponding fan coil unit 124.

In this embodiment, a master controller 132 for controlling each air conditioning controller 126 is further provided, and the master controller 132 and each air conditioning controller 126 are connected by a communication line. In association with the master controller 132, a carbon dioxide concentration detector 40 'for detecting the carbon dioxide concentration in the chamber 12 and a humidity sensor 42' for detecting the humidity in the chamber 12 are provided. The master controller 132 further includes the above equations 21 and 2

0 and a center temperature setting unit 122 are provided, and the center temperature setting unit 122 sets an initial temperature value, for example, 26 ° C. in summer and 22 ° C. in winter. These setting devices 118, 1
Each of 20 and 122 is constituted by a variable resistor or a potentiometer, and is connected to the AI terminal of the master controller 132. Therefore, each set value is input to the master controller 132 as an analog value, and the master controller 132 converts the analog value into a digital value (data) and gives it to the air conditioning controller 126 through the communication means. 126 to the indoor controller 66 '
Given to.

The indoor controller 66 'in this embodiment is the same as the indoor controller 66 shown in FIGS.
This is almost the same except that the air volume cannot be set. Therefore, here, the indoor controller 66 'should be recognized as being equivalent to the indoor controller 66. Therefore, also in the embodiment of FIG.
The CPU 82 (FIG. 3) of the indoor controller 66 'executes the steps S1 to S7 of FIG. 6 to calculate the PMV value, and after executing the step S11 or S13 through the judgment step of the step S9, proceeds to the step S15.

The control data according to the V value or the PMV value is given to the air conditioning controller 126. Therefore, the air conditioning controller 126 controls the inverter circuit 130 according to the PMV value or the control data, controls the rotation speed of the motor, that is, the blower fan 128, that is, the blower amount, or controls the electric valve 136 of the heat exchanger 134, The amount of cold water or hot water flowing through the heat exchanger 134 is adjusted to control the air blowing temperature.

In the embodiment shown in FIG. 10, the master controller 132 can be replaced by one air conditioning controller 126. That is, in the embodiment of FIG. 11, one of the plurality of air conditioning controllers 126 is provided in FIG.
