Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of an air conditioning control device for saving energy in a building.

[0002]

2. Description of the Related Art Generally, in a building such as an existing office, about 1/2 of the energy consumption of the entire building is used for air conditioning equipment and about 1/3 is used for lighting equipment. The rest of the energy is used by elevators and office automation equipment.

By the way, in air-conditioning equipment which occupies the maximum ratio of energy consumption, control and measures for realizing various energy saving have been conventionally taken. For example, the optimum start / stop control of the air conditioner, the enthalpy control for determining the optimum intake amount of outside air to perform the air conditioning control, the zone control related to the device of the present invention, and the intermittent operation control of the air conditioner can be mentioned.

The conventional zone control and air conditioner intermittent operation control will be described below. (1) Zone control When considering the air conditioning control of the whole building, if there is only one air conditioning system in the whole building, even if there is some temperature unevenness, it is impossible to handle it. An appropriate temperature environment can be created by finely dividing the area into several zones and individually controlling the air conditioning in each zone. Such independent air conditioning for each area is called a zone control method. Here, the zone means one area, and the zoning described later means that the inside of the building is divided into several areas and each is independently air-conditioned.

Now, let us consider from FIG. 5 why the division is necessary. Now, for a building with windows facing north, south, east, and west as shown in Fig. 7 (a), when the heat load is calculated by dividing the zone into north, south, east, and west, the east zone, west zone, and south The sensible heat load in the zone and the north zone appears as a change as shown in FIG. Of these sensible heat loads, the load due to solar radiation from the window occupies a large proportion of the entire outer peripheral load, so the time at which the maximum load occurs in each zone is roughly determined according to the movement of the sun. The east zone is around 8am, the south zone is around 12:00, the west zone is around 4pm in the evening, and the north zone is around 3pm.

Therefore, as is clear from FIG. 5 (b), the load of each zone varies with the passage of time, so that an air conditioner capable of individually controlling the air conditioning is required for each zone. Come on. If zoning is ignored and one air conditioner is installed in the building itself, as shown in the graph of FIG. 5 (c), the temperature becomes appropriate only during the time when maximum load occurs in each zone, but other In the case of the time zone, it is always too cold. When it is too cold, it is bad for human health and is uneconomical for heat.

Therefore, if the outer peripheral portion of the building is zoned according to the east, west, south, and north directions, the entire building can be efficiently air-conditioned. On the other hand, the inner circumference of the building is
Since the load fluctuations are relatively small, there is little effect even if they are combined into one zone. The outer peripheral zone on the window side is called a perimeter, while the inner peripheral zone is called an interior (reference: air conditioning for 1 million people, Junpei Ohara, publisher Ohmsha Co., Ltd.). (2) Regarding intermittent operation control of air conditioners It is no exaggeration to say that energy saving of air conditioning equipment is generally to shorten the operating time of air conditioners.

Here, the optimum start (stop) control of the air conditioner is a method of shortening the operation time before and after the use time zone of the room, whereas the intermittent operation control is to provide comfort during the use time zone. The air conditioner is forcibly stopped intermittently to the extent that it is not damaged.

By the way, in the conventional intermittent operation control method, as shown in FIG. 6, a permissible value of about ± 1 ° C. is set with respect to a predetermined set temperature, and after the room temperature reaches the upper limit, the lower limit is reached. In this method, the air conditioner is stopped until the allowable value is reached, and the operation is restarted only when the lower limit allowable value is reached. However, this control method is for heating.

[0010]

By the way, when zone control is performed in a modern building in winter, the perimeter (window side) is used.
Even if the zone is in heating operation, in the interior (inside room) zone, cooling operation is often performed in consideration of heat generated by OA equipment, lighting, human body, and the like. As a result, in the boundary region between the perimeter zone and the interior zone, there is often a case where energy is canceled by the mixture of the heating air and the cooling air, that is, heat loss occurs. This means that the heating operation is performed to the full capacity on the perimeter side and the cooling operation is performed to the full capacity on the interior side, so that the mixing loss becomes extremely large.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an air conditioning control device for realizing energy saving of an air conditioning facility in a building. Another object of the present invention is to provide an air conditioning control device that prevents a mixing loss between the temperature of the heating operation in the perimeter zone and the temperature of the cooling operation in the interior zone in the winter.

Further, another object of the present invention is to provide an air conditioning control device capable of thoroughly saving energy by performing appropriate intermittent operation control. further,
Another object of the present invention is to provide an air conditioning control device that realizes energy saving of air conditioning equipment while sufficiently considering comfort.

[0013]

In order to solve the above-mentioned problems, the invention according to claim 1 provides an air conditioner for each zone when the perimeter zone and the interior zone of a building are operated at different set temperatures. Each of the air conditioners is an air conditioning control device that controls not only the outside air but also the return air from different zones so as to reach the set temperature.

Next, the invention according to claim 2 is an air-conditioning control device for heating and operating a perimeter zone of a building and cooling an interior zone of the building in winter, in which return air and outside air of different zones are provided. And a temperature setting means for setting the set temperature of the perimeter zone for performing the heating operation to be lower than the set temperature of the interior zone for performing the cooling operation, and an air conditioner installed in each zone. It is an air conditioning control device provided with a blower and an air conditioning control means for controlling the air conditioner so as to adjust the temperature of the mixed air of the mixing means in order to set the temperature to the set temperature of the temperature setting means.

Further, the invention according to claim 3 is, as the air conditioning control means of the invention according to claim 2, (1) air conditioner operation, return for the air conditioner, return fan and blower for each zone. Fan and blower operation, (2) Air conditioner stop,
There is a means for performing intermittent operation control that is repeated in the cycle of the blower and blower stoppage, (3) air conditioner stoppage, and return blower and blower operation.

Further, the invention according to claim 4 is, as the temperature setting means of the invention according to claims 1 and 2, a predicted average answer for obtaining a comfort index for each zone based on at least zone environmental factors. A means for determining a set temperature at which the comfort index on the perimeter zone side is close to the lower limit of the comfortable range, and a comfort index on the interior zone side close to the upper limit of the comfortable range And a means for determining the set temperature.

[0017]

Therefore, in the inventions corresponding to claims 1 and 2, by taking the above-mentioned means, the air conditioner on the side of the perimeter zone is designed to effectively utilize the temperature difference between the perimeter zone and the interior zone. Using the temperature of the zone, the air conditioner on the side of the interior zone uses the air of the temperature of the perimeter zone, and more specifically, it sets the set temperature of the perimeter zone for heating operation to a lower temperature while operating the cooling operation. The interior zone is set to a higher temperature, the air conditioner on the perimeter zone side incorporates a lower temperature in the interior zone to adjust the temperature, and the air conditioner on the interior zone side incorporates a higher temperature in the perimeter zone. As the temperature is adjusted, the mixing loss at each zone temperature can be reduced, and the air conditioner in each zone consumes less energy. It can be the over down temperature to a predetermined temperature.

Further, the invention according to claim 3 is an intermittent operation control which is repeated in a cycle in which only the air conditioner is stopped after the air conditioner, the return fan and the blower are operated / stopped, and only the return air fan and the blower are operated. As a result, it is possible to maintain the air-conditioning environmental conditions while making the best use of the heat storage capacity of the building itself, and to reduce the actual operating time of the air conditioner as compared with the conventional intermittent operation control, and to significantly reduce the energy consumption of the air conditioner.

Further, in the invention according to claim 4, by determining the set temperature of each zone by using the comfort index, it is possible to sufficiently consider human comfort, and to achieve mixing loss and energy saving. .

[0020]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an overall configuration diagram showing an embodiment of the invention according to claims 1 and 2. In the figure, reference numeral 1 denotes a window attached to the outer wall 2 of the building, and a predetermined required area of the outer peripheral portion of the building including the window 1 is defined as a perimeter zone 3p, and the inner peripheral portion of the building excluding the outer peripheral portion of the building. The predetermined area is defined as the interior zone 3i. Each of these zones 3p, 3i has a controller 4p, 4i and a controller 4 for directly controlling the air conditioning equipment of its own zone.
Air-conditioning equipment that operates according to the control command from p.4i is installed.

A thermometer 5p for measuring the temperature of the perimeter zone 3p is connected to the perimeter controller 4p, and a set temperature SV for heating the perimeter zone 3p, for example 23 ° C., is set. Therefore, the controller 4p executes a predetermined required control based on the deviation between the set temperature SV and the temperature measured by the thermometer 5p. On the other hand, the interior controller 4i
Like the perimeter-side controller 4p, a thermometer 5i for measuring the temperature of the interior zone 3i is connected, and further, a set temperature S for cooling the interior zone 3i is set.
V, for example, 26 ° C. is set. The controller 4i executes a predetermined required control based on the deviation between the set temperature SV and the temperature measured by the thermometer 5i. As the set temperature SV of each zone, the set temperature SV of the interior zone 3i performing the cooling operation is always set higher than the set temperature of the perimeter zone 3p performing the heating operation.

The air-conditioning equipment is installed in each zone 3p, 3i. The air conditioning equipment on the side of the perimeter zone 3p takes in the return air from the interior zone 3i and then exhausts a part of it to the outside of the building and recirculates the remaining air, and the interior from this return fan 6p. Air mixing means 7p for synthesizing the return air of the zone 3i and the fresh air inside / outside the building
, Air filter AF, air cooler (cooling coil) C
C, an air heater (heating coil) HC, a humidifier (steam spray) SS and the like air conditioner 8p for perimeter,
The air blower 9p is configured to blow air from the air conditioner 8p to the perimeter zone 3p.

On the other hand, the air conditioning equipment on the interior zone 3i side has the same structure. That is, after the return air from the perimeter zone 3p is taken in, a part of the return air is exhausted to the outside of the building, for example, and the remaining air is circulated, and the interior zone 3i from the return air fan 6i.
Air mixing means 7i for synthesizing the return air of the air and the fresh air inside and outside the building, and the air filter AF,
An interior air conditioner 8i including an air cooler (cooling coil) CC, an air heater (heating coil) HC, a humidifier (steam spray) SS, and the like, and a blower for blowing air from the air conditioner 8i to the interior zone 3i. 9i and.

Therefore, in such a configuration of the air conditioning control device, since the interior zone 3i is cooling-operated at a higher set temperature in the interior zone 3i, the interior zone 3i becomes the environmental temperature based on the set temperature. It is set. On the other hand, on the side of the perimeter zone 3p,
The return air blower 6p takes in the high-temperature return air from the interior zone 3i and introduces it to the perimeter air conditioner 8p side. Here, on the side of the air conditioner 8p for the perimeter, the return air having a high temperature from the interior zone 3i sent from the return air blower 6p is mixed with the outside air, and the return air is mixed with the controller 4p based on the control command based on the set temperature. Since the temperature is adjusted and the air is blown to the perimeter zone 3p by the blower 9p, the return air having a high temperature intersects with the set temperature (23 ° C) by the controller 4p, and the perimeter zone 3p can be easily operated for heating to prevent mixing loss. Energy saving can be achieved.

On the interior zone 3i side, return air having a low temperature is taken from the perimeter zone 3p by the return blower 6i and introduced to the interior air conditioner 8i side. Here, on the interior air conditioner 8i side, the return air having a low temperature on the perimeter zone 3p side sent from the return fan 6i is mixed with the outside air, and the control 4i
The temperature of the return air is adjusted on the basis of the control command based on the set temperature and is blown to the interior zone 3i by the blower 9i. Therefore, the return air having a low temperature and the set temperature (26 ° C) by the controller 4i intersect each other, and 3i can be easily cooled, and it is possible to prevent mixing loss and save energy.

Next, an embodiment of the invention according to claim 3 will be described. In this embodiment, the zone controllers + intermittent operation control are carried out by the controllers 4p and 4i of each zone, and the intermittent operation control is such that the air conditioning equipment is operated and controlled in the order shown in FIG. Since the controllers 4p and 4i of the zones 3p and 3i perform the same intermittent operation control, the intermittent operation control by the controller 4p of the perimeter zone 3p will be described below, and the intermittent operation control by the controller 4i of the interior zone 3i will be described below. Omit it. (1) The controller 4p includes an air conditioner 8p and a return fan 6
p, if the operation of the blower 9p is continued, the zone temperature of the perimeter zone 3p will be within the allowable value of the set temperature of 23 ° C ± 1 ° C. (2) When the zone temperature of the perimeter zone 3p is within the allowable value, the controller 4p causes the air conditioner 8p and the return blower 6 to operate.
p, the blower 9p is stopped. When the stop state of each of these devices continues, the zone temperature of the perimeter zone 3p gradually decreases and the zone temperature of the interior zone 3i gradually increases with the passage of time. (3) Further, if the zone temperature of the perimeter zone 3p exceeds the set allowable value, the controller 4p stops the operation of the air conditioner 8p, and returns the blower 6p and the blower 9p.
By adding only the air in the low temperature perimeter zone 3p to the high temperature interior zone 3i or adding the high temperature interior zone 3i to the low temperature perimeter zone 3p,
Maintain the required air conditioning conditions as much as possible. And
When the air condition set in the state of (3) cannot be maintained, the state of (1), that is, the air conditioner 8p, the return fan 6p, and the blower 9p are operated. By thus performing the intermittent operation control in which the cycles (1) to (3) are repeated, the operation time of the air conditioner 8p is shortened.

Therefore, according to the intermittent operation control of this embodiment, the temperature of the perimeter zone 3p becomes lower and the temperature of the interior zone 3i becomes higher in the stopped state (2). Then, the temperature of such a zone is exchanged as much as possible by the operation of the above (3). That is,
The air conditioning condition is kept as much as possible by adding the air in the perimeter zone 3p having a low temperature to the interior zone 3i having a high temperature or by adding the air in the interior zone 3i having a high temperature to the perimeter zone 3p having a low temperature. To do. Further, when the air conditioner 8p is in the operating state as described in (1), crossing the return air from the set temperature SV further shortens the operation time of the air conditioner, as compared with the conventional case where the return air is not crossed. The energy saving can be further promoted.

Further, an embodiment of the invention according to claim 4 will be described with reference to FIG. This embodiment is an example of calculating each set temperature of the perimeter zone 3p and the interior zone 3i in consideration of human comfort. Since the calculation of the set temperature of the interior zone 3p is the same, the description thereof is omitted here.

This device, as shown in FIG.
p, an air conditioner 8p and a blower 9p are provided, and the air conditioner 8p converts the high temperature air on the interior zone side and the set temperature into the intersecting temperature air, and then the blower 9p
The air is sent to the perimeter zone 3p in the building by p. In this perimeter zone 3p, a thermometer 5p, an average radiation thermometer 11p, a hygrometer 12p and an air velocity meter 13 are provided.
p is provided to measure process variables such as zone temperature, average radiant temperature, humidity and air velocity that affect the human thermal sensation.

The zone temperature measured by these measuring devices,
Average radiation temperature, humidity, air velocity, etc.

A comfort set temperature calculation unit 14p for calculating the set temperature of p is provided.

The comfort set temperature calculation unit 14p calculates the average airflow velocity from the airflow velocity sent from the airflow velocity meter 13p via the controller 4p, and the average airflow velocity calculation unit 15p. PMV calculating means 16p for calculating the comfort index relating to the thermal sensation based on the average air velocity obtained by the above, the zone temperature measured by the measuring device, the average radiant temperature, the humidity, and the amount of clothes and the amount of activity as necessary. , The control amount setting means 17p for obtaining the set temperature so that the comfort index obtained by the PMV calculating means 16p falls within a predetermined range.
And is constituted by. The PMV is Pred
Abbreviation for icted Mean Vote.

The set temperature obtained by the control amount setting means 17p is sent to the controller 4p, where an operation signal is obtained based on the set temperature and the temperature measured by the thermometer 5p.
The openings of the steam valve 18p, the hot water valve 19p and the cold water valve 20p are adjusted to control the air conditioner 8p.

Next, the operation of the above apparatus will be described. Now, the zone temperature, the average radiation temperature, the humidity, the air velocity, etc. measured by the thermometer 5p, the average radiation thermometer 11p, the hygrometer 12p, the air velocity meter 13p, etc. are sent to the PMV calculation means 16p through the controller 4p. . In this case, the airflow velocity measured by the airflow velocity meter 13p is averaged by the average airflow velocity calculating means 15p and then sent to the PMV calculating means 16p. At this time, at the same time, the factors caused by human beings from the outside, that is, the activity amount (work amount) and the clothing amount for each season according to the indoor use are PM
It is input to the V calculation means 16p.

By the way, the PMV calculating means 16p calculates a comfort index relating to thermal sensation under the following conditions. The amount of heat generated by human beings is the sum of the amount of radiation due to convection, the amount of radiation due to radiation, the amount of heat of evaporation from humans, the amount of heat released from breathing and the amount of heat storage. When these heat balance equations are established, the human body is It is neutral and comfortable with neither hot nor cold weather. On the contrary, when the thermal equilibrium equation is broken, the human body feels cold.

As a human thermal sensation index based on the above heat balance equation, the PMV (predictive average answer) described above is one that has recently received attention. For an overview of this PMV,
"Air Conditioning and Sanitary Engineering Society, Air Conditioning and Sanitary Engineering Handbook 1
Volume, Vol. 1, Chapter 3, "and" Japan Refrigeration Society, "Advanced Standard Text-Refrigeration and Air Conditioning Technology", Chapter 14. "This PMV was proposed by Fanger. Then, starting from the comfort equation announced by him, the heat load of the human body and the thermal sensation of human beings are combined and expressed in seven levels.

This comfort equation incorporates various heat radiation calculation equations into the heat balance equation with the surrounding environment in a steady state where the body temperature of the human body is kept constant, and further, skin temperature and perspiration evaporative emission as physiological quantities. This is derived by giving a comfortable condition of heat quantity. This equation can be used to determine the zone temperature required for thermal comfort, taking into account the six variables. Of the six variables, the activity amount is usually the metabolic amount met (1met = 50k
cal / m ² · h), the amount of clothing is clo (1 cl
o = 0.18 m ² · h · ° C / kcal).

The PMV index is obtained by calculating the actual metabolic amount and the amount of heat imbalance between the environment and the clothing under clothing conditions as the heat load L on the human body using the above-mentioned comfort equation. Is tied together. The thermal sensation is expressed as a numerical value based on a rating scale of 7 levels.

Therefore, the PMV calculating means 16p calculates the comfort index regarding the thermal sensation based on the above conditions. This comfort index takes a continuous value from -3 to +3, and is expressed as a numerical value according to a 7-level evaluation scale as the thermal sensation.

+3: hot, +2: warm, +1: rather warm, 0: neither (comfortable), -1: rather cool, -2: cool, -3: cold. Such a comfort index represents an average evaluation given to the comfort of a given room by a person in the room. For example, there are 5 people in an office without partitions, and Mr. A is a little warmer (+1).
B feels cool (-2), C feels a little cool (-1), D feels a little warm (+1), and E feels a little cool (-1). . At this time, the average heat rating, that is, the average answer (MV) is obtained as follows.

MV = (1-2-1 + 1-1) / 5 = -2
/5=-0.4 Correspondence between predicted average response PMV, which is an index of thermal sensation, and human body load L obtained from Whanga's equation is statistically analyzed from data by a large number of subjects, and the predicted average. The answer PMV is given by the following equation as a function of the human body load L and the metabolic rate M.

PMV = {0.352.exp (-0.0
42 · M) +0.032) · L where M is the metabolic rate (kcal / m ² · h) and L is the human body heat load (kcal / m ² · h). FIG. 4 shows a numerical example of PMV.

The comfort index calculated by the PMV calculating means 16p as described above is sent to the control amount setting means 17p, where the comfort index falls within a predetermined human comfortable range ± 0.5. Yes, for example -0.5 <comfort index <
If it is +0.5, it is determined that the person is comfortable. At this time, the set temperature of the perimeter zone for heating operation is
Since the temperature is set lower than the set temperature of the interior zone in which the cooling operation is performed, the set temperature of the perimeter zone is set to near -0.5 which is the lower limit of the comfortable range, and the set temperature of the interior zone is set to the upper limit of the comfortable range. Somewhere near +0.5. If the comfort index is out of the comfortable range, the zone temperature at which the comfort index falls within the comfortable range is calculated back using the measured values other than the corresponding zone input to the PMV calculation means 16p. The value is sent to the controller 4p as the set temperature.

The controller 4p has a control amount setting means 17
The openings of the steam valve 18p, the hot water valve 19p, and the cold water valve 20p are adjusted based on the set temperature input from p and the set humidity input in advance. In this case, the control amount setting means 17p uses the zone temperature and the measured values other than the zone temperature to back-calculate the zone temperature and the zone humidity so that the comfort index falls within the comfortable range, and these values are set to the set temperature and Alternatively, the set humidity may be input to the controller 4p.

In the apparatus of FIG. 3, PMV was used as the comfort index, but this PMV was obtained by statistically analyzing questionnaire data from a large number of Western and European subjects. If this is used as it is for individual air conditioning control systems in Japan, it may deviate from the actual human sense. Therefore, in order to obtain the comfort index according to the individual air conditioning control system and the occupant of the building, a means for correcting the PMV by learning using the neuron technique may be used.

Further, in the embodiment according to claim 3, the judgment of the operation / stop of the intermittent operation control is obtained from the zone temperature. However, the operation / stop of the intermittent operation control is performed by using the comfort index shown in FIG. May be determined. Other,
The present invention can be variously modified and implemented without departing from the scope of the invention.
