Setting test technology trends in the heating, ventilation and air conditioning sector
Heating, ventilation and air-conditioning systems are becoming increasingly intelligent. For example, the industry speaks about “smart heating” and intelligent heating and ventilation technology.
Typical trends see the merging of previously separate units into integrated and connected systems. Hybrid heating systems with multiple heat generators open up new possibilities for linking renewable heat sources. Demand is also increasing for decentralised air extraction systems with heat recovery.
At the same time, statutory minimum requirements for energy efficiency and energy savings are also on the increase. This is all creating a dilemma: more functions, more software, extremely diverse plant components and increasing connectivity are making systems more complex. The functionality of such systems must be accurately simulated and tried and tested at the development stage. Increasingly more parameters and tighter limitsmust be taken into account. There is therefore a considerable increase for measurement and testing as well as for greater performance from measurement technology.
Trends in industrial measurement and testing technology
- Increasing standards and tighter limits require increasingly detailed and precise measuring technology which can be adapted by users to actual test needs. In addition to measurement, control and automation technology, test systems therefore also require control software that is flexible to operate.
- Higher demands on connectivity. Increasing networking requires universal inputs for sensor technology, both open and proprietary interfaces as well as standardized protocols. Users expect complete solutions to cover all relevant interfaces. If measuring devices such as scales or gas meters from third parties have to be integrated, their reliable connection is also part of the required complete solution.
More extensive testing requirements, higher performance requirements
- More extensive measurement and testing requirements also leads to more complex and larger test benches. The required test scope and the number of measurement parameters are increasing and a wide variety of test technologies must be used. Users expect test solutions to flexibly integrate new requirements.
- Higher performance requirements. Larger, more powerful test benches with more measurement parameters also require the measurement and control technology to be performance-oriented. This includes, for example, faster measurement inputs that can also handle sampling rates of 50,000 measured values per channel and per second. Additional functions, such as internal computing channels and monitoring functions, also require a high level of performance.
High-quality measurement and testing technology for heating, ventilation and air conditioning
- Example Heating test standsBecause the test benches have to cover a wider range of tests, a catalog of test devices for various test tasks was developed with a major manufacturer of heating systems. Universal inputs for temperature and pressure sensors as well as for analog and digital inputs mean that new test requirements can be implemented independently by the user. The measurement technology (such as ProfiMessage and Expert Logger) is connected via the Delphin Software re-parameterized as required. This means that the testing technology only needs to be configured, but not reprogrammed, which considerably simplifies operation.
- Example Cooling and air conditioning units: For refrigeration and air conditioning appliances, for example, real-life use is simulated in climate chambers and different components are tested for their requirements. The test specimens are tested under precisely controlled pressure and temperature profiles, vibrations and refrigerant flow rates in a practical manner. Various profiles can be selected via a "one-button solution" and the independent testing techniques can be controlled synchronously. The measurement automation also enables online analyses to be carried out during the test. Stored substance databases and tables facilitate the evaluations. The devices also automatically detect faults and limit violations and report them via a switching output or email.
- Example Checking the energy efficiency labelIn such standard-compliant tests, for example, various parameters are monitored at over 20 different temperature measuring points. The integrated control technology takes over the setting of different ambient temperatures. The same system can also be used to carry out several tests in parallel and independently of each other. The software can record, process and save an unlimited number of channels and up to 30 test stands in parallel.
