Solution Overview
Problem
Existing test rooms for heating-cooling systems are inefficient and inflexible, particularly when testing systems of varying sizes, as they require large investments and space, and often only allow partial testing due to limited adaptability.
Innovation Solution
A modular test room with a control unit, sensors for temperature and humidity, and an aeraulic circuit featuring direct and water heat exchangers, along with a method for controlling air circulation and humidity, allowing for precise temperature and humidity control across a wide range, and the ability to adapt module configurations for different system sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a test room is dimensioned for large-sized systems, then it can accommodate large systems, but it shows limited efficiency when used to test systems of smaller size
Solution Approach 1:
The test room is divided into multiple independent modules that can be individually configured. Each module contains its own compartment and aeraulic circuit, allowing the test room to be segmented into different active testing zones based on the size of the system being tested, thereby maintaining high efficiency across varying system dimensions
Solution Approach 2:
The test room employs dynamic configuration capabilities through movable partition walls and selective activation of modules. This allows the testing space to be dynamically adjusted and reconfigured to match the dimensions and requirements of different systems, optimizing testing efficiency for each specific application
2Adaptability or versatility
If a test room is designed with fixed configuration, then it is simple to operate, but it cannot enable testing of the whole machine for systems of varying size
Solution Approach 1:
The test room consists of multiple standardized modules that can be independently configured and combined. Each module is a self-contained unit with compartment and aeraulic circuit, allowing flexible assembly to match different testing requirements without creating excessive overall system complexity
Solution Approach 2:
The modules are designed with universal interfaces and standardized configurations that allow them to serve multiple functions. The same module type can be used for different system sizes by varying the number and arrangement of active modules, reducing the need for specialized configurations for each testing scenario
3Measurement precision
If conventional heat exchangers are used, then the structure is simple, but the temperature control precision is insufficient for reproducing exact climate conditions
Solution Approach 1:
The aeraulic circuit integrates both direct expansion heat exchanger and water heat exchanger into a unified system. This combination allows the system to leverage the high precision temperature control of direct expansion for critical temperature points while using water heat exchangers for broader climate conditioning, achieving exact climate reproduction through synergistic operation
Solution Approach 2:
The water heat exchanger serves as an intermediary between the external environment and the test compartment, providing buffered temperature control. This intermediary approach allows for smoother temperature transitions and more precise climate reproduction by mediating the thermal exchange process

Function Achieved in This Case
The modular design enables efficient testing of systems of various sizes by recreating precise climate conditions, allowing for both heating and cooling, and flexible use by separating or combining modules, thus overcoming the limitations of prior test rooms.
Implementation Method 1
activating the direct expansion refrigeration cycle in order to cool the air to the set temperature
Implementation Method 2
supplying said heat exchanger with glycolated water at a temperature higher than 0°C and lower than the external air temperature introduced into the compartment so as to cool and dehumidify the air through condensation of the vapour contained in the air
Implementation Method 3
supplying said heat exchanger with glycolated water at a temperature lower than 0°C and higher than the set temperature so as to cool and dehumidify the air through frosting of the vapour contained in the air
Implementation Method 4
The aeraulic circuit comprises a means for forced air circulation along the channels
