Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air source heat pump systems have high energy consumption, environmental pollution issues, and inefficiencies due to the lack of comprehensive energy use and cold energy storage, leading to increased power grid demands and costs. Additionally, they require multiple systems for heating and cooling, and are not adaptable to different power standards, increasing production and user costs.
Innovation Solution
An intelligent cloud-controlled air source heat pump system with integrated ice storage and heat recycling, using Over-the-Air updates, DC variable speed motors, and a double-pipe heat exchanger, which automatically adjusts ice storage capacity based on weather forecasts and ambient temperatures, allowing for unified equipment design and reduced power grid load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate cooling and heating systems are used to meet different temperature requirements, then cooling and heating functions are achieved, but energy consumption increases and investment costs double
Solution Approach 1:
The patent combines cooling and heating systems into a single integrated unit that can switch between modes. The system uses a unified heat pump mechanism that can operate in both cooling and heating modes, eliminating the need for separate systems and reducing overall energy consumption while maintaining both functions.
Solution Approach 2:
The integrated system performs multiple functions (cooling, heating, and hot water supply) through a single multi-functional device. The heat pump system can adapt its operation to provide different thermal services based on seasonal and daily temperature variations, maximizing resource utilization.
2Loss of energy
If ice storage system is used to store cold energy at night, then daytime cooling demand is met, but system complexity increases
Solution Approach 1:
The system performs preliminary cooling action during nighttime hours when electricity rates are lower and demand is reduced. Ice or cold energy is stored in thermal storage tanks during these off-peak hours, then released during daytime peak demand periods, effectively shifting the cooling load and improving energy efficiency.
Solution Approach 2:
Thermal storage tanks serve as intermediary devices between the heat pump system and the cooling demand. These tanks store thermal energy in the form of ice or chilled water, acting as a buffer that decouples the cooling supply from immediate demand and enables load shifting.
3Ease of manufacture
If control parameters are fixed for different power standards, then equipment can be manufactured for specific regions, but production costs and user costs increase
Solution Approach 1:
The control system incorporates dynamic adaptability to different power standards through software configuration rather than hardware redesign. The system can dynamically adjust its operating parameters and control logic to accommodate different voltage frequencies (50Hz/60Hz) and power requirements, allowing a single design to serve multiple regions.
Solution Approach 2:
The system allows modification of control parameters to adapt to different power standards. By changing software parameters and control settings rather than manufacturing different hardware versions, the system can accommodate various regional power specifications, reducing production complexity and cost.
