Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heating systems in residential units face challenges in integrating renewable energy technologies due to space constraints and inefficiencies, particularly in apartment buildings where large-volume systems are required for both water circulation and fresh water heating, limiting the share of renewable energy in total energy consumption.
Innovation Solution
A compact heating system that connects a heat pump and a heat generator in series, with a storage tank, allowing the heat pump to preheat water which is then further heated by the generator, enabling a smaller volume and lower heating capacity for both components, and increasing the use of renewable energy by utilizing the heat pump to heat both fresh water and the fluid used for building temperature control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a heat pump system is used to heat both fresh water and heating water in apartment buildings, then the share of renewable energy increases, but the required system volume and space requirements become too large for available installation areas
Solution Approach 1:
The patent combines the fresh water heating function and heating water circulation function into a single integrated heat pump system. The heat pump serves dual purposes: heating fresh water for domestic use and heating the heating water circulation system for space heating. This merging of functions allows apartment buildings to utilize renewable energy for both heating needs without requiring separate large-volume systems, thus resolving the contradiction between increasing renewable energy share and reducing system volume.
2Ease of manufacture
If separate systems are used for fresh water heating and heating water circulation, then each system can be optimized independently, but the total space requirement and system complexity increase
Solution Approach 1:
The heat pump system is designed with universal functionality to perform both fresh water heating and heating water circulation. The system includes a heat pump unit, a storage tank for fresh water, and a heating water circulation system with heat exchangers. The heat pump can operate in different modes to serve both functions, reducing the need for separate dedicated systems while maintaining optimization capabilities through controlled operation modes.
3Use of energy by stationary object
If large-volume heat pump systems are installed for heating both fresh water and building heating, then renewable energy coverage is maximized, but installation space in existing apartment buildings becomes insufficient
Solution Approach 1:
The patent implements a nested configuration where the heating water circulation system is integrated within or alongside the fresh water heating system. The heating water circuit components, including heat exchangers and circulation pumps, are arranged to utilize the space occupied by the fresh water storage tank and heat pump unit. This nesting approach allows the system to provide maximum renewable energy coverage while minimizing the footprint in existing apartment building installations.
