3.3.7. Running Power Estimation

Calculate energy consumption based on the operating parameters of the device or system (such as power rating, usage time, duty cycle, and different operating modes). By considering these factors, we can determine the total energy required to operate the device within a specified time, thereby helping to optimize energy use and identify potential savings opportunities.

After adding Running Power Estimation as an Extension node, click the plus sign to add it to the workflow editing area. Enter the key thresholds for device operation, such as maximum power, light level, temperature, etc. In the Type field, you can select the type of device, including:

• HVAC: This is a system used for heating, ventilation, and air conditioning. It typically includes heaters, air conditioners, ventilation equipment, and air handling units, mainly used to regulate the temperature, humidity, and air quality inside a building to provide a comfortable living or working environment.
• Light: This refers to devices used for lighting, usually including various types of lamps, such as incandescent lamps, fluorescent lamps, LED lamps, etc. Lighting devices are used to provide visible light to illuminate indoor or outdoor spaces. The result will output the estimated running power data of the device.

Result Testing

• For Light type, the running power estimation input parameter content is a JSON field, displaying the running power array, including vlight and pmax fields, example data: {"Vlight":20,"Pmax":2000}
• For HVAC type, the running power estimation input parameter content is a JSON field, displaying the running power array, including aircon_outdoor_units, aircon_indoor_units, outdoor_env fields, example data: {"aircon_outdoor_units":[{"max_power":[5500],"efficiency_ratio":[2.1],"elec_meter_uuid":"u001"}],"aircon_indoor_units":[{"switch":"on","mode":"cold","set_temp":26.5,"uuid":"u001","elec_meter_uuid":"u001","space_id":"101","temp":20.4,"humidity":76.5}],"outdoor_env":{"temp":20.2,"humidity":66.3}}

The output for Light is: [34300]

The output for HVAC is: [1.611358880996704]

Note: Test data can be obtained by moving the mouse to the question mark in the upper left corner and clicking on the corresponding type.
