Solution Overview
Problem
Conventional fan coil units experience inefficient air flow distribution, leading to non-uniform temperature distribution, which is not adequately addressed by existing designs that use squirrel or axial fans with vanes or deflectors, resulting in suboptimal heating and cooling efficiency.
Innovation Solution
A fan coil unit with a housing featuring three outlet areas arranged beside each other on the top side, where the two outer outlet areas are inclined between 120° and 160° relative to the middle outlet area, equipped with fans blowing air through each outlet area, and an air stream heat exchanger, enhancing air flow distribution and heat emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional squirrel fans or axial fans with vanes or deflectors are used to distribute air, then air flow distribution is improved, but device complexity and manufacturing cost increase significantly
Solution Approach 1:
The housing top side is segmented into three distinct outlet areas (first, second, and third outlet areas) with different inclination angles. This segmentation allows each outlet to direct air flow in optimized directions without requiring complex internal vanes or deflectors, achieving effective air distribution through simple geometric division of the outlet structure.
Solution Approach 2:
The invention transitions from conventional single-plane outlet designs to a three-dimensional configuration where outlet areas are arranged at different inclination angles on the top side of the housing. The first outlet area is inclined at a first angle, the second outlet area at a second angle, and the third outlet area at a third angle, creating spatial diversity in air flow directions without adding mechanical complexity.
2Temperature
If air is blown upwards or downwards by conventional fans, then heating or cooling is achieved, but temperature distribution becomes non-uniform
Solution Approach 1:
Different outlet areas are assigned different inclination angles to create localized air flow patterns. The first outlet area inclined at a first angle, the second at a second angle, and the third at a third angle, each contributing to uniform temperature distribution in different spatial zones. This local differentiation of outlet characteristics ensures comprehensive and uniform thermal coverage throughout the room.
