Introduction
In-depth interpretation of the standard test method for thermal performance of marine heat exchangers
| Parameter name | Temperature deviation requirement | Flow deviation requirement | Media type |
|---|---|---|---|
| Cooler test | ±0.5℃ | ±1% | Oil, water, air |
| Heater test | ±0.5℃ | ±1% | Steam, oil, water |
| Condenser test | ±0.5℃ | ±1% | Steam, water |
Test system requirements
According to the standard, the test system must have the function of automatically controlling the medium temperature and flow rate. During the test, the temperature deviation of each operating point should not exceed ±0.5℃, and the flow rate deviation should not exceed ±1%.
Medium selection and accuracy requirements
The standard specifies the test medium corresponding to different heat exchanger types:
- Oil cooler uses diesel engine oil with quality grade CC in GB11122-2006.
- Water cooler and condenser use clean fresh water.
- Air cooler uses air medium.
Measuring instrument accuracy requirements
The accuracy of temperature, pressure and flow measuring instruments must meet the requirements of Tables 1 to 3. For example:
| Instrument Name | Accuracy |
|---|---|
| Thermometer | 0.25% |
| Pressure Transmitter | 0.5% |
Implementation Suggestions
To ensure the accuracy and reliability of the test, it is recommended that:
- Strictly control the test environment temperature and humidity and keep them within the standard requirements (5℃~30℃, 85% or less).
- Select measuring instruments that meet the accuracy requirements and calibrate them regularly.
- Reasonably design the variable working condition test plan to ensure that the number and interval of measuring points meet the standard requirements.
