Heat Exchanger Development and Validation, from Design Calculations to Proven Performance
Developing a competitive heat exchanger requires much more than selecting tube diameters, fin geometries or refrigerant circuits. Today's manufacturers must balance thermal performance, pressure drop, refrigerant quantity, material costs and manufacturability while meeting increasingly demanding efficiency and cost targets.
The development process therefore starts with modelling. Using advanced simulation tools, engineers can evaluate design concepts, optimise geometries and compare alternatives long before a prototype is built. Modelling significantly reduces development time and cost by enabling manufacturers to focus on the most promising designs. However, even the most sophisticated models rely on assumptions and empirical correlations. Factors such as refrigerant distribution, airflow maldistribution, manufacturing tolerances, surface characteristics and operating conditions are difficult to predict with complete accuracy. As a result, actual performance often differs from simulated performance.
This is where testing becomes essential
Rather than replacing modelling, testing complements it by validating assumptions, improving model accuracy and providing the confidence needed for critical design decisions. The most successful heat exchanger developments combine simulation expertise with accurate laboratory testing.
At Re/Gent, we support both stages of the development process. Our specialists perform heat exchanger modelling during the design phase to evaluate and optimise concepts before prototype construction. Subsequently, our advanced testing facilities provide the measured performance data needed to validate designs and confirm that performance targets are achieved in practice.
The result is a faster development process, reduced technical risk and, ultimately, a heat exchanger that delivers the optimal balance between performance and cost.
How Re/Gent Supports Heat Exchanger Manufacturers
During the early design phase, Re/Gent performs thermal and system-level modelling to evaluate design concepts and identify optimisation opportunities before prototypes are manufactured.
Our modelling activities help manufacturers:
- Compare multiple design concepts
- Optimise heat transfer performance
- Reduce pressure drop
- Minimise refrigerant charge
- Assess the impact of new refrigerants
- Reduce development time and prototype costs
- Identify the most promising design direction
- Independent Performance Testing
Once prototypes are available, we validate actual performance under controlled laboratory conditions and compare measured results with simulation predictions.
We perform accurate and repeatable testing of:
- Evaporators
- Condensers
- Other heat exchangers used in refrigeration systems or heat pumps
- Air-to-liquid heat exchangers
- Liquid-to-liquid heat exchanger
Testing data can be used to refine simulation models, helping manufacturers continuously improve future product development.
Cost and Performance Optimisation
The best heat exchanger is not necessarily the one with the highest thermal performance. It is the one that delivers the required performance at the lowest overall cost.
By combining modelling, testing and engineering analysis, Re/Gent helps manufacturers identify the optimum balance between:
- Efficiency
- Capacity
- Refrigerant mass
- Material usage
- Production costs
Design with confidence & Validate with certainty
Re/Gent combines heat exchanger modelling, independent testing and engineering expertise to help manufacturers develop evaporators, condensers, air-to-liquid and liquid-to-liquid heat exchangers that achieve the optimal balance between performance, manufacturability and costs.
From the first design calculations to final performance validation, we help transform promising concepts into commercially successful products.
