Solution Overview
Problem
Existing methods for estimating energy saving effects in air-conditioning systems fail to account for variations in power consumption under the same conditions and do not reflect loads that vary independently of outside air temperature, leading to degraded accuracy in power consumption estimation.
Innovation Solution

1Ease of manufacture
If a multiple regression formula or average measured value is used to estimate reference power consumption, then the estimation method is simple, but variations in power consumption under the same condition are not taken into consideration, degrading estimation accuracy
Solution Approach 1:
The heat load is segmented into two distinct components: a first heat load that varies according to outside air temperature and a second heat load that varies independently of outside air temperature. This segmentation allows the estimation model to account for both temperature-dependent and temperature-independent variations in power consumption, thereby improving accuracy while maintaining model simplicity.
Solution Approach 2:
The invention introduces a new parameter (second heat load) that varies independently of outside air temperature to the existing estimation model. By changing the parameters considered in the regression formula to include both temperature-dependent and temperature-independent components, the model achieves higher accuracy without becoming overly complex.
2Ease of operation
If a simple relation formula P = a × T + b is used between outside air temperature and power consumption, then the calculation is straightforward, but loads that vary independently of outside air temperature are not reflected, degrading estimation accuracy
Solution Approach 1:
The heat load is segmented into two distinct components: a first heat load that varies according to outside air temperature and a second heat load that varies independently of outside air temperature. This segmentation allows the estimation model to account for both temperature-dependent and temperature-independent variations in power consumption, thereby improving accuracy while maintaining model simplicity.
Solution Approach 2:
The invention adds another dimension to the estimation model by introducing a parameter (second heat load) that operates independently of the outside air temperature dimension. This dimensional expansion allows the model to capture variations in power consumption that occur regardless of temperature changes, improving accuracy while keeping the calculation framework straightforward.
