Air conditioning device and air conditioning system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioning devices with vertically disposed heat exchangers often suffer from dew condensation water staining the periphery of the installation site, leading to unsightly stains and potential mold growth, which is both aesthetically undesirable and hygienically problematic.
Innovation Solution
The air conditioning device incorporates a support frame with inclined outer shell bodies and a reflector to direct dew condensation water away from the installation site, utilizing a gutter-shaped receiving portion to collect and redirect water, preventing it from splattering or dripping onto the surrounding area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If heat exchangers are vertically disposed to eliminate draft sensation, then heating/cooling efficiency is improved, but dew condensation water stains the installation site periphery
Solution Approach 1:
The patent utilizes the harmful dew condensation water by providing a receiving portion that collects the water and a discharge portion that directs it away from the installation site. The reflector also plays a role by reflecting radiant heat while being positioned to work with the water drainage system, converting the harmful staining effect into a controlled discharge process that prevents damage to the installation environment.
Solution Approach 2:
The receiving portion acts as an intermediary between the heat exchangers and the installation site surface. It collects dew condensation water from the heat exchangers and transfers it to the discharge portion, preventing direct contact between the water and the installation site, thereby eliminating the staining problem while maintaining the vertical heat exchanger configuration.
2Use of energy by moving object
If reflector is disposed at back side to improve heat radiation efficiency, then radiant heat reflection is improved, but convective air carries dew condensation water to splatter on front side
Solution Approach 1:
The patent segments the functional zones by positioning the reflector at the back side separated from the front side discharge portion. This spatial segmentation allows the reflector to perform heat radiation reflection at the back while the discharge portion handles water drainage at the front, preventing the convective air from carrying water against the reflector and causing splattering.
Solution Approach 2:
The discharge portion serves as an intermediary that intercepts dew condensation water before convective air can carry it to the front side. It provides a controlled discharge path that prevents water from being entrained in the convective airflow, thereby eliminating the splattering problem while maintaining reflector positioning for optimal heat radiation.
3Area of stationary object
If outer shell bodies are horizontally disposed, then heat exchange surface area is maximized, but dew condensation water drips onto installation surface
Solution Approach 1:
The patent converts the harmful dripping effect by providing a receiving portion that captures dew condensation water from the horizontally disposed heat exchangers. The water is then directed through the discharge portion away from the installation site, transforming the potential staining problem into a controlled drainage system that preserves the horizontal configuration for maximum heat exchange surface area.
Solution Approach 2:
The receiving portion and discharge portion together form an intermediary drainage system between the heat exchangers and the installation site surface. This intermediary structure collects water from the horizontal heat exchange surfaces and redirects it away from the installation area, preventing dripping stains while maintaining the optimal horizontal orientation for heat exchange.
