An air conditioning range is set on a psychrometric diagram by an air conditioner operation method and an outside air intake method using a target temperature of setting data, and an indoor temperature increased value when an air conditioner is stopped and the minimum outside air is taken in at current time in accumulated data by an actual measured value in each season and in each time, or an indoor temperature increased value or an outdoor humidity decreased value when the air conditioner is stopped and the maximum outside air is taken in and thereby, even the resident having small air conditioning technique can monitor and control the energy saving air conditioning operation.

Description

  The present invention relates to an air-conditioning monitoring and control device that enables an occupant to perform an energy-saving air-conditioning operation in a building or facility in which a building multi-air conditioner or an air conditioner is installed.

  Office buildings and multi-air conditioners for buildings and air conditioners in facilities that adjust the temperature are often temperature-controlled, but ventilation equipment is often installed independently, and energy-saving air-conditioning operation by outside air cooling control linked to air-conditioner operation is possible. I can't. Also, in buildings and facilities where the air conditioning manager is not resident and the resident operates the air conditioner, if the air conditioner operation is started at the start of the operation, even if the cooling or heating becomes unnecessary, the continuous operation is wasted until the end of the operation. .

  Current problems

  In an office building or facility where a resident operates an air conditioner, if the resident starts a “heating or cooling” operation using an air conditioner at the start of work, the outside air temperature will change even if the indoor temperature rises due to OA equipment. Even if the “heating or cooling” operation is not required, the operation is continued until the end of the operation. In offices that generate a lot of heat, such as OA equipment, in the winter and mid-terms, “air-conditioning operation” is often performed, although it can be cooled by “outside air”.

  Since the resident can freely set the temperature of the air conditioner, the recommended temperature setting for energy saving, for example, the energy saving temperature setting of heating 20 ° C. and cooling 28 ° C. is not strictly observed.

  Cause of a problem

  Multi-air conditioners for buildings and air conditioners are installed, and air conditioning equipment for office buildings and facilities adjusts the temperature, but ventilation equipment is often installed independently, and strict energy-saving air conditioning by outside air cooling control linked to air conditioner operation I can't drive. In addition, since there is no outdoor temperature or outdoor humidity monitoring device at the place where the occupant operates the air conditioner, it cannot be determined that the air conditioner operation is unnecessary.

  Residents of offices and various facilities have little knowledge of air conditioning and cannot perform accurate energy-saving air-conditioning operation. In addition, since the occupants can freely set the temperature of the air conditioner, energy-saving temperature air-conditioning operation is not thoroughly implemented.

  There is no air-conditioner or heat source automatic stop function even when air-conditioner operation is unnecessary, and air-conditioning equipment that automatically performs cooling operation in winter and heating operation in summer to adjust the indoor temperature to the set temperature.

The air conditioning range from (1) to (9) is set using the measured values of temperature and humidity, the indoor target temperature, and the following α value, β value, and γ value of this patent. In energy-saving air-conditioning judgment, which is performed periodically, the optimum air-conditioning method is judged by predicting the indoor temperature using “outdoor measured temperature + (α value or β value)” in addition to the indoor temperature measured value as the indoor temperature. Heating / stopping / cooling control output to the equipment, and overheating / supercooling by controlling the minimum outside air intake or outside air volume control or maximum outside air intake to the outside air cooling equipment.

It is characterized by giving the residents a sense of security.

  According to the “energy-saving air-conditioning monitoring and control device” of the present invention, the following effects can be obtained.

  Energy saving effect

  Regardless of the temperature setting of the air conditioner body during air conditioning heating and cooling, energy saving air conditioning is judged by the winter target temperature (for example, 20 ° C.) and the summer target temperature (for example, 28 ° C.) of the indoor target temperature of the “energy saving air conditioning monitoring and control device” of the present invention. Because air conditioning operation / stop control is performed, heating / cooling operation with excessive temperature setting can be prevented, and energy-saving operation can be achieved even if an air conditioning engineer is not stationed.

  When it is determined that heating or cooling is unnecessary, the air conditioner or the heat source is controlled to be stopped, so that unnecessary continuous heating or cooling operation can be prevented and energy saving can be achieved.

  The outside air cooling control includes the “(5) AC stop / outside air adjustment” range, the “(6) AC stop / outside air adjustment” range, the “(7) AC stop / maximum outside air” range, and the “(8) AC cooling / Since it is strictly performed over a wide range of “maximum outside air”, cooling operation using a heat source is minimized and energy saving can be achieved.

  Humidity control is performed so that the humidity is below the indoor upper limit humidity, so energy use by dehumidification that performs overcooling and reheating can be minimized.

  Comfort maintenance effect

  Since the indoor humidity is controlled to be lower than the upper limit humidity (for example, 60%), the indoor humidity can be kept comfortable.

  In the case of a sudden change in the air conditioning load that causes the outdoor humidity to become high during outdoor air cooling due to “maximum outside air” and the outdoor air cooling is stopped to make it “minimum outside air”, the optimal air conditioning by the predicted value of “indoor predicted temperature = outdoor measured temperature + α value” Since the method is judged, it is possible to suppress a sudden fluctuation of the indoor temperature and maintain a comfortable target temperature as compared to judging the air conditioning method at the current indoor measured temperature.

  Labor saving effect

  For energy-saving air conditioning operation, it is not necessary to regularly measure outdoor temperature / humidity and indoor temperature / humidity, and it is also necessary to operate the air conditioner and take in outside air when the air conditioning operation method is changed. Because there is not, it becomes labor saving of resident and can concentrate on original duties.

  Safety effect

  Expertise in air conditioning and air conditioning is provided by “temperature display”, “humidity display” and “energy-saving air condition display” on the airline diagram in the “energy-saving air-conditioning monitoring and control device” display panel installed in the air-conditioner operation unit of the living space. Even few residents can easily understand the optimal energy-saving air-conditioning operation state and give a sense of security.

  The α value is a temperature difference between the indoor temperature and the outdoor temperature in the “AC stop / minimum outside air” state, and is obtained by the following equation. The minimum outside air is the minimum ventilation volume for hygiene management. "Α value (℃) = Indoor measurement temperature (℃)-Outdoor measurement temperature (℃)"

  The α value is used to predict the indoor temperature using the formula “predicted indoor temperature = outdoor measured temperature + α value” in addition to the indoor measured temperature when setting the air conditioning range and determining energy-saving air conditioning for the minimum outside air. Improving the indoor temperature control response speed when the air conditioning load suddenly changes, such as changing the air conditioning range from the maximum outside air to the minimum outside air, and intuitively determining the air conditioning range when the minimum outside air is taken in the temperature display section It is used as an index to make it possible.

  After the heating operation is started, the heating operation is normally continued when the heating operation becomes unnecessary due to the thermal load fluctuation.However, in the case of the following expression using the α value during the heating operation, the heating stop is predicted and judged. “AC stop” control is performed to save energy. "Heating stop temperature (for example, 21 ° C) ≤ Outdoor measurement temperature (° C) + α value (° C)"

  Since the α value varies depending on the time depending on solar radiation, personnel fluctuations, usage amount of OA equipment, etc., for example, it has 8 time series data every 3 hours from 0:00 to 24:00. In order to make a strict judgment, the α value may be set with more data by shortening the time interval.

  The α value is set to the “(2) Air conditioner stopped / minimum outside air” state at the specified time within the time-series data time by performing “α value setting” operation of the data setting function. The α value (° C.) can be calculated and updated at the time of energy saving air-conditioning judgment of the period. Furthermore, in order to maintain the α value at a value that matches the latest actual conditions, if the energy saving air conditioning judgment is in the range of “(2) AC stop / minimum outside air”, the α value is calculated by the above formula and the corresponding time data Update.

  Since the α value varies depending on the season, there are three types of time-series data: winter, intermediate, and summer, and the α value at the corresponding time is set by the “α value setting” operation at the change of the indoor target temperature season as described above. It can be updated to a value that matches the latest reality.

  β value

  The β value is a temperature difference between the indoor temperature and the outdoor temperature in the “AC stop / maximum outside air” state, and is obtained by the following equation. The maximum outside air is the maximum outside air intake amount. "Β value (℃) = Indoor measurement temperature (℃)-Outdoor measurement temperature (℃)"

  The β value is used to determine the optimal air conditioning method when determining the energy saving air conditioning when setting the air conditioning method and controlling the outside air cooling, and to determine whether to stop the cooling operation or change the indoor temperature when changing the air conditioning method to the indoor target temperature. This is used as an index for making it possible to intuitively determine the optimum air-conditioning method at the time of outside air cooling (control) in the control display speed improvement and the temperature display section. The β value is used for prediction of indoor temperature using the formula of “predicted indoor temperature = outdoor measured temperature + α value” in addition to the indoor measured temperature when setting the air conditioning range and determining energy-saving air conditioning at maximum outside air, and determining cooling stop In addition, the control response speed of the indoor temperature is improved when the air conditioning load changes suddenly, such as when the air conditioning range is changed from the minimum outside air to the maximum outside air, and the air conditioning range during outdoor air cooling (control) is intuitively determined in the temperature display section. It is used as an index to make it possible.

  When cooling operation is no longer necessary due to fluctuations in the heat load after starting cooling operation, cooling operation is normally continued.However, in the case of the following formula using β value during cooling operation, it is predicted to be `` cooling stopped '' Perform “AC stop control” to save energy. “Outdoor measurement temperature (° C.) + Β (° C.)” ≦ “Cooling stop temperature (for example, 27 ° C.)”

  Since the β value varies depending on the time depending on solar radiation, fluctuations in personnel, usage amount of OA equipment, and the like, for example, it has 8 time series data every 3 hours from 0:00 to 24:00. In order to make a strict judgment, the β value may be set with more data by shortening the time interval.

  The β value is forcibly set to the “(7) Air conditioner stopped / maximum outside air (intake)” state at the specified time within the time-series data time by performing the “β value setting” operation of the data setting function. Thus, the β value (° C.) can be updated when energy-saving air conditioning is determined in the next cycle. To maintain the β value at the latest value, if the energy saving air-conditioning judgment is in the range of “(7) AC stop / maximum outside air”, the β value is calculated using the above formula and the corresponding time data is updated. To do.

  Since the β value varies depending on the season, there are three types of time-series data: winter, mid-term, and summer, and the β value at the corresponding time is set by the “β value setting” operation at the change of the indoor target temperature season. It can be updated to a value that matches the latest reality.

  Judgment conditions by humidity

  FIG. In the “Energy Saving Air Conditioning Judgment Concept Concept Diagram (Judgment by Humidity)”, “2. Energy Saving Air Conditioning Judgment by Humidity” shows the judgment condition of whether to execute or stop the outdoor air cooling depending on the outdoor humidity.

  This “energy-saving air-conditioning monitoring and control device” saves energy through thorough outdoor air-cooling control. However, when the outdoor humidity is high, the indoor humidity comfort is impaired or dehumidification energy is used. It is set, and it is judged whether the outside air cooling is executed or the outside air cooling is stopped so as not to exceed this humidity during the outside air cooling. When it is determined that the outdoor humidity exceeds the “outdoor upper limit humidity”, FIG. Perform “1.2 Judgment at minimum outside air (high humidity)”. When the outdoor humidity is equal to or lower than the “outdoor upper limit humidity”, FIG. Perform “1.3 Judgment at the time of outside air cooling (control)”.

  γ value

  “Outside air cooling” is generally determined using enthalpy calculation or a dew point thermometer, but in this patent, a γ value is used as an index for performing measurement using a hygrometer.

  “2.1. Outdoor humidity drop value (hereinafter referred to as γ value)” in FIG. 4 is a value in which the (relative) humidity drops due to an increase in β value (° C.) indoor temperature due to outside air intake. Ask for. The absolute humidity (kg / kg) value on the saturation curve with respect to the temperature on the air diagram is stored as a numerical table, and the saturated absolute humidity at the outdoor temperature t1 is increased by x1 (kg / kg) and β (° C) temperature When the saturated absolute humidity at the measured temperature t2 (° C.) is x2 (kg / kg). For example, when the “indoor upper limit humidity” is set to 60%, the following formula is used. Outdoor humidity drop value γ (%) = (x2−x1) (kg / kg) × 60% ÷ x2 (kg / kg) When “indoor upper limit humidity” is changed, the changed humidity may be substituted. .

  In “2.2. Air Conditioning Cancellation and Air Conditioning Return Air Conditioning Judgment by Humidity” in FIG. 4, in order to keep the indoor humidity below the upper limit of comfortable humidity, for example 60%, In this case, it is determined that the outside air can be cooled. "Outdoor measurement humidity (%)" ≤ "Indoor upper limit humidity (eg 60%) + γ value (%)"

  When the energy saving air-conditioning is judged, the outdoor air cooling is judged to be canceled if the following condition is satisfied. "Indoor maximum humidity (eg 60%) + γ value (%)" <"Outdoor measurement humidity (%)"

  The judgment of returning from the outside air cooling to the outside air cooling is performed under the following condition when judging the energy saving air conditioning in order to prevent control hunting. “Outdoor measurement humidity (%)” <“Reset humidity of outside air (for example, 55%) + γ value (%)”
