Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional multi-type air conditioner systems experience non-uniform heating, leading to discomfort and increased noise, as they radiate hot air concentrated near ceilings, and inefficiently control indoor temperatures, resulting in significant power waste when idle.
Innovation Solution
A multi-type air conditioner system comprising an outdoor machine, indoor machine, pipe set, and controller, with electromagnetic valves and electronic expanding valves, allowing refrigerant cycling between machines for precise temperature control, eliminating the need for heating water in underfloor pipes to prevent freezing and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If hot air is transmitted to indoor through ceiling vents, then heating function is provided, but temperature distribution becomes non-uniform and users feel hot at heads and cold at feet
Solution Approach 1:
The patent inverts the conventional ceiling-ventilation heating approach by implementing underfloor heating. Instead of delivering hot air from the ceiling downward, the system heats the floor surface which then radiates heat upward, creating uniform temperature distribution from the ground up and eliminating the head-hot/feet-cold sensation.
Solution Approach 2:
The patent utilizes hydraulic principles by circulating heated water through pipes embedded in the floor structure. This water-based heating system replaces air-based convection heating, allowing thermal energy to be distributed uniformly through the floor surface via fluid circulation.
2Temperature
If fan air pressure and transmission speed are increased to reach preset temperature, then heating effectiveness is improved, but indoor noise becomes more apparent
Solution Approach 1:
The patent replaces mechanical air circulation (pneumatic system requiring high-speed fans) with a hydraulic heating system. Heated water circulates through floor pipes, transferring thermal energy without requiring high-velocity air movement, thereby eliminating fan-generated noise while maintaining heating effectiveness.
Solution Approach 2:
The patent substitutes the mechanical air-forcing system (fans and ducts) with a passive thermal radiation system. The hydraulic heating system transfers energy through fluid circulation and thermal conduction/radiation from the floor surface, replacing the noisy mechanical air movement with quieter thermal physics-based heating.
3Temperature
If heating water is continuously circulated in underfloor pipes, then heating function is provided, but power is wasted when system is idle
Solution Approach 1:
The patent implements periodic action by controlling the water circulation pump to operate only when heating is required. The system includes a controller that activates the pump based on temperature sensors and user settings, stopping circulation when the target temperature is reached or when the system is idle, thereby eliminating continuous energy consumption.
Solution Approach 2:
The heating system incorporates self-service through automatic temperature control. Temperature sensors continuously monitor indoor conditions and automatically regulate pump operation and water flow, eliminating the need for continuous manual operation and preventing energy waste when heating is not needed.
