  The present invention relates to an air-conditioning control support screen generation device, an air-conditioning control support screen generation method, and an air-conditioning monitoring system that monitor air conditioning in an office, a residence, or the like.

  About half of the energy consumed in the entire building facilities such as offices and residences is energy related to air conditioning. Therefore, the promotion of energy saving related to air conditioning control greatly contributes to energy saving of the entire building facility.

  On the other hand, in a room that is subject to air conditioning control, it is required to ensure so-called comfort in order to satisfy the thermal sensation of the occupants.

  There is a trade-off between this “promotion of energy conservation” and “ensuring the comfort of occupants”, and the promotion of energy conservation often reduces the comfort of occupants. By suppressing the excessive energy consumption exceeding, it is possible to suppress wasteful energy consumption while ensuring the comfort of the occupants.

  As described above, there is an environmental energy management system to which the agent technology described in Patent Document 1 is applied as a technology for promoting energy saving while ensuring the comfort of occupants.

  The environmental energy management system described in Patent Document 1 is composed of a plurality of agent devices installed in individual areas for air conditioning control, and a management manager device connected to the plurality of agent devices via a network. The agent device acquires measurement values from sensors in each area, and the management manager device acquires data from each agent device to perform thermal environment calculation and energy optimization calculation using a comfort index such as PMV. By controlling the air-conditioning equipment, it is possible to achieve both optimization of the indoor thermal environment and minimization of energy consumption.

  By the way, in large-scale facilities such as office buildings and hospitals, in addition to air conditioning control by the system as described above, the central management device acquires and displays the environmental state of each room so that the operator can monitor this environmental state. In addition, the set value of the air conditioner is operated.

  As a technique for displaying the indoor environmental state, there is a driving support system described in Patent Document 2.

  This operation support system includes costs related to operation target facilities, energy supply costs for operation target facilities, operating equipment costs, carbon dioxide emissions, nitrogen oxide emissions, global warming material emissions, primary energy consumption, crude oil equivalent Energy consumption, energy supply / demand deficiency, power quality, or the like is displayed as an evaluation result of operation information performed on the driving equipment.

With this driving support system, the operator's driving know-how, energy-saving advice by machines, energy-saving optimal calculation, etc. can be utilized, and the operator's willingness to save energy can be further increased.

  PMV is a variable that affects human thermal sensation against heat and cold. (A) Air temperature, (b) Relative humidity, (c) Average radiation temperature, (d) Air velocity, (e) Activity ( It is a comfort index determined using six of the internal heat generation amount of the human body) and (f) the amount of clothes.

  The amount of heat generated by a person is the sum of the amount of radiation generated by convection, the amount of heat released by radiation, the amount of heat evaporated from the person, the amount of heat released by breathing, and the amount of stored heat.If these thermal balance equations hold, the human body is thermally neutral. It is a comfortable state that is neither hot nor cold. Conversely, when the thermal balance equation breaks down, the human body feels hot and cold.

  In 1967, Professor Fanger of the Danish Institute of Technology announced the derivation of the comfort equation, and using this as a starting point, the thermal load of the human body and the thermal sensation of the human were statistically analyzed from a questionnaire of a large number of European and American subjects, PMV was proposed. In recent years, this has been taken up by the ISO standard and has recently been used frequently.

PMV, which is an index of thermal sensation, is expressed as a numerical value based on the following seven-level evaluation scale.
+3: Hot +2: Warm +1: Slightly warm 0: Neither comfort, -1: Slightly cool -2: Cool -3: Cold is there.

Of the above six variables, the amount of activity representing work intensity usually uses the unit of metabolic rate met, and the amount of clothing uses the unit of clo.
The unit met (met) represents the amount of metabolism, and 1 met is represented by the following formula (1) with reference to resting metabolism in a thermally comfortable state.

  In addition, the unit clo (cloth) represents the thermal insulation of clothes, and 1 clo is a room temperature of 21 ° C, relative humidity 50%, air flow 5cm / s or less, and the amount of heat released from the body surface is balanced with metabolism of 1met. It is a value in such a clothing state, and is expressed by the following formula (2) when converted into a normal thermal resistance value.

  From these numerical values, using the following formula (3), within a comfortable range (−0.5 <PMV <+0.5), the PMV is on the hotter side during cooling and on the colder side during heating. By setting the target value, the air conditioning load can be reduced, and energy saving can be achieved.

<Operation of the air conditioning control support system according to the first embodiment>
Next, operation | movement of the air-conditioning control assistance screen generation apparatus 60 of the air-conditioning control assistance system 1 by this embodiment is demonstrated with reference to the flowchart of FIG.

  First, the outside air temperature of the equipment subject to air conditioning control is measured by the outside air temperature sensor 101 included in the outdoor sensor group 10, and the outside air humidity is measured by the outside air humidity sensor 102, and these outside air temperature measurement values and outside air humidity measurements are measured. The value is input to the outside air state measurement value input unit 601 of the air conditioning control support screen generation device 60 via the monitoring control system 50 (S1).

  In addition, the temperature in the zone subject to air conditioning control is measured by the indoor temperature sensor 201 included in the indoor sensor group 20, and the humidity in the zone is measured by the indoor humidity sensor 202. The measurement value is input to the indoor state measurement value input unit 602 of the air conditioning control support screen generation device 60 via the monitoring control system 50 (S2).

  In the monitoring control system 50, the indoor temperature setting value and the indoor humidity setting value in the air conditioning control target zone are calculated based on the acquired outside air temperature measurement value, outside air humidity measurement value, room temperature measurement value, and room humidity measurement value, It is transmitted to the air conditioner 30 and the air conditioning control support screen generator 60. Further, the supply air temperature setting value and the supply air humidity setting value set in the air conditioner 30 are calculated from the temperature set value and the humidity set value, and transmitted to the air conditioner 30 and the air conditioning control support screen generation device 60.

  Next, the indoor temperature setting value and the indoor humidity setting value in the zone targeted for air conditioning control calculated in the monitoring control system 50 are input to the indoor setting value input unit 603 of the air conditioning control support screen generation device 60 (S3). Then, the supply air temperature set value and the supply air humidity set value are input to the supply air set value input unit 604 (S4).

  Next, the air conditioner 30 estimated from the outside air temperature measurement value input from the outside air state measurement value input unit 601 and the amount of heat estimated to be exhausted from lighting, OA equipment, etc. in the zone subject to air conditioning control. Sensible heat load amount is calculated, and the estimated latent heat load amount in the air conditioner 30 is calculated from the outside air humidity measurement value and the water vapor amount estimated to be discharged from the occupant in the zone subject to air conditioning control. It is calculated by the sensible heat load / latent heat load calculation unit 605 (S5).

  When the sensible heat load / latent heat load calculation unit 605 calculates the estimated value of the sensible heat load and the latent heat load in the air conditioner 30, the supply air flow rate is based on the sensible heat balance and the latent heat balance in the zone subject to air conditioning control. Is calculated (S6).

The sensible heat balance and the latent heat balance in the air-conditioning control target zone will be described.
Within the zone subject to air conditioning control, the sensible heat is adjusted so that the following formula (4) is satisfied, thereby balancing the amount of heat.

Tsa：給気温度設定値
である。

Where Qs: Zone sensible heat load

Hsa：給気湿度設定値
である。

Where lw: latent heat load
ρ: Air density
Hr: Indoor humidity measurement

  In order to satisfy this equation (4), the supply air flow rate with respect to the sensible heat balance is calculated based on the input supply air flow rate, the indoor temperature setting value, the supply air temperature setting value, and the calculated sensible heat load amount. The air supply flow rate for the latent heat balance is calculated based on the input indoor humidity measurement value, the supply air humidity setting value, and the calculated latent heat load so that the air supply flow rate of 1 is calculated and the expression (5) is satisfied. A second supply air flow rate that is a flow rate is calculated, and a total amount of the first supply air flow rate and the second supply air flow rate is calculated as a necessary total supply air flow rate.

  Further, the cold water flow rate is calculated based on the heat transfer amount of the cold water coil 301 in the air conditioner 30 (S7).

The heat transfer amount of the cold water coil 301 in the air conditioner 30 will be described.
The heat transfer amount of the cold water coil 301 is calculated from the calculated sensible heat load and latent heat load by the following equation (6).

ここで、Cstm：水蒸気の蒸発熱
である。

Here, Cstm is the heat of vaporization of water vapor.

  The calculated heat transfer amount of the cold water coil 301 satisfies the following formula (7).

In the above equation (7), the coil thermal conductivity (k) is a coil model calculated from the thermal conductivity coefficient (k ₀ ), the wetting surface coefficient (Cws), the coil cross-sectional area (S), and the number of coil stages (N). Since the cold water coil inlet temperature, which is the temperature of the cold water supplied to the air conditioner 30, is preset in the central heat source, the cold water flow rate is calculated from the above formulas (6) and (7).

  Next, the power consumption value of the blower fan 302 in the air conditioner 30 is calculated by the blower fan power calculation unit 608 from the supply air flow rate (Fsa) calculated in step S6 (S8). At this time, when the differential pressure is constant, it is calculated by the blower fan power model of the following formula (8), and when the differential pressure is variable, it is calculated by the blower fan power model of the following formula (9).

Fsa0：定格給気流量
である。

Where Qfan: Power consumption value of the blower fan
Qfan0: Power consumption value of the blower fan when the supply air flow rate is Fsa0

  Further, the power consumption value of the water pump 403 in the air conditioner 30 is calculated by the water pump power calculator 609 from the cold water flow rate (Fch) calculated in step S7 (S9). At this time, in the case of an open system of a high-rise building, the water pump power model of the following formula (10) is calculated.
