Heat-Exchange Water Bypass Layout for Precise Air Humidity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioning systems for large buildings have complex structures and high costs due to numerous components, including multiple valves and piping, which complicates installation and maintenance.
Innovation Solution
The air conditioning system simplifies structure and reduces costs by minimizing piping length and the number of valves through a configuration where the second water passage branches off from the first, allowing precise control with only two water regulating valves and incorporating a humidifier for energy-efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple two-way valves and series piping are used to control heat-exchange water flow through multiple heat exchangers, then temperature and humidity control precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges multiple separate water flow control paths into a single integrated water passage. Instead of using multiple two-way valves to control separate heat exchanger circuits, the invention uses one three-way valve to distribute heat-exchange water between multiple heat exchangers sharing a common water passage, thereby reducing valve count from four to one while maintaining control precision
Solution Approach 2:
The single three-way valve performs multiple functions that previously required four separate two-way valves. It controls water flow distribution to the first heat exchanger, the second heat exchanger, and enables bypass flow, effectively replacing multiple specialized valves with one multi-functional component
2Productivity
If four two-way valves are installed to regulate heat-exchange water flow rates through multiple heat exchangers, then air-conditioning performance is improved, but manufacturing cost and installation complexity increase
Solution Approach 1:
The patent combines multiple water flow control functions into a single integrated system. Instead of installing four separate two-way valves in different locations, the invention uses one three-way valve with a common water passage that serves multiple heat exchangers, reducing installation complexity and manufacturing cost while preserving air-conditioning performance
Solution Approach 2:
The invention extracts the essential function of water flow regulation from multiple distributed valves and consolidates it into a single three-way valve located at one point in the system. This centralizes the control function and eliminates the need for multiple valve installations
