Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pneumatic radiation units have complex structures, leading to high costs and inefficiencies in creating comfortable air conditioning without drafty feelings or temperature irregularities.
Innovation Solution
A pneumatic radiation unit with a simple structure comprising a first chamber and a second chamber, where the second air discharger has a greater aperture ratio than the first, allowing for gradual reduction in air flow velocity and increased static pressure, enabling uniform air distribution and heat radiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex structure with multiple components (air feeder, air inducer, air mixer) is used to achieve comfortable air conditioning, then air conditioning comfort is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines the functions of air supply, air induction, and air mixing into a single integrated radiation unit with two chambers. The first chamber supplies air through a first air discharger, while the second chamber induces and mixes air through a second air discharger with greater aperture ratio, eliminating the need for separate air feeder, air inducer, and air mixer components.
Solution Approach 2:
The patent changes the aperture ratio parameter of the air dischargers, specifically making the second aperture ratio greater than the first aperture ratio. This parameter change enables the simplified structure to achieve proper air flow control, induction, and mixing functions that previously required complex separate components.
2Manufacturing precision
If air flow velocity is reduced gradually with increased static pressure, then uniform air distribution is achieved, but flow passage design complexity increases
Solution Approach 1:
The patent applies different aperture ratios at different locations - the second air discharger has a greater aperture ratio than the first air discharger. This local quality variation in the flow passage design enables gradual reduction of air flow velocity and increase of static pressure without requiring complex flow control mechanisms throughout the entire passage.

AI summary
A pneumatic radiation unit according to the present invention includes: a first chamber, through which air-conditioning air flows; and a second chamber configured to take in the air-conditioning air from the first chamber and discharge the air-conditioning air and radiate heat to a space to be air conditioned. The first chamber includes a first air discharger that is in contact with the second chamber and configured to discharge the air-conditioning air to the second chamber. The second chamber includes a second air discharger that is in contact with the space to be air conditioned and configured to discharge the air-conditioning air to the space to be air conditioned. A second aperture ratio of the second air discharger is set to be greater than a first aperture ratio of the first air discharger, or a cross-sectional area of a flow passage of the air-conditioning air in the first chamber is gradually reduced from an upwind side to a downwind side of the flow passage of the air-conditioning air.
