Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heat pump type heating systems face challenges in maintaining comfort and reducing power consumption, as existing control methods do not adequately account for the characteristics of heating apparatuses, leading to unnecessary electricity consumption and potential failure to maintain set room temperatures during output suppression periods.
Innovation Solution
A heat pump control device that receives outside temperature information and adjusts output water temperatures dynamically, switching from a first setting temperature to a second setting temperature during output suppression periods, with the difference in output water temperatures increasing as the first output water temperature rises, to optimize power consumption and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the heat pump output water temperature is reduced during output suppression periods to decrease power consumption, then power consumption is reduced, but the room temperature may not be maintained at the set temperature
Solution Approach 1:
The control device determines a second output water temperature in advance before the output suppression period begins. This preliminary determination ensures that the room temperature can be maintained at the set temperature even when power consumption is reduced during the suppression period, by pre-calculating the appropriate temperature adjustment based on heat radiation characteristics
Solution Approach 2:
The control device changes the output water temperature parameter from the first output water temperature to the second output water temperature during the output suppression period. The second temperature is determined to be lower than the first, but specifically calibrated to maintain room temperature, representing a controlled parameter change that balances energy reduction with performance maintenance
2Use of energy by moving object
If a fixed reduction in output water temperature is applied during output suppression periods, then power consumption is reduced, but unnecessary electricity may be consumed due to not accounting for heating apparatus characteristics
Solution Approach 1:
The control device determines the second output water temperature based on the specific heat radiation characteristics of the individual heating apparatus. This localized, customized approach ensures that the temperature reduction is precisely tailored to the apparatus's properties, avoiding unnecessary energy consumption that would result from a generic fixed reduction
Solution Approach 2:
The control device uses the heat radiation characteristics of the heating apparatus as feedback to determine the appropriate second output water temperature. This feedback mechanism ensures that the temperature adjustment is optimized for the specific apparatus, preventing both excessive temperature reduction (which would waste energy) and insufficient reduction (which would fail to save energy)

AI summary
The present disclosure relates to a heat pump control device that controls a heat pump type heating device that supplies heat to a heating device from a heat pump. The heat pump control device outputs, to the heat pump type heating device, first information indicating a first output water temperature according to outside temperature by using a memory that manages output water temperature of the heat pump for maintaining the space at a first setting temperature in relation to the outside temperature. The control unit outputs second information to the heat pump type heating device in order to switch from the first setting temperature to the second setting temperature in the output suppression period in which supply and demand adjustment is performed between the consumer house and an electricity system, the second information indicates a second output temperature which is different from the first output water temperature more largely as the first output water temperature becomes higher if the outside temperature is the same,.
