TESTING HEAT EXCHANGERS

TESTING HEAT EXCHANGERS

If we want to test heat exchangers we should build testing rooms to cover compressor,tank,adapter which are necessary for testing but also air dryer,filter and utilizing from a bybass line are beneficial for our testing systems in order to raise our air qualities.
Air quality is a vital part of our testings because air quality effects heat exchanger tests directly.We desire to clean heat exchangers with using air if air which we use for the process has some particules can plug our heat exchangers and it may cause some damages on it.To avoid this we should use filter by progressive stages.The first filter can detain more bigger molecules such as dust and the second one protect the systems from more smaller particles such as odors,micromolecules.
We can suppy heat exchangers with using compressor in order to produce enough air to clean it directly.But it is not efficent way because air which is supplied from compressor directly can have variable both flow and output to avoid this problem we can put a tank after the compressor enables us steady flow for the accurate testing.Reserving enough space to operate compressor properly is a important point,we should be informed by the producer of compressor which we have used.Making enough space to operate compressor also is a vital part of maintanence of its.When maintenance time of compressor comes,workers will need to enough space to avoid bug and to protect them from injury accidents.
Ducts should be adequate to carry enough air to the heat exchangers’ adapters which must withstand appropriate pressures.If does not,it may cause some injury accidents.It is also provided from manufacturers.
Good perfomance is dependent on a good installation.Even the best machines will only perform well if they have been properly installed.A poor installation can affect machine performance.It can also create costly service problems.
A good installation requires proper planning procedures which is presented clause by clause at below.
• Do you have enough space in your compressor room?
• Have you made provision for adequate ventilation?
• Do you have the right dimensions fort he air intake ducting?
• Does the air provide adequate flow rate?
• Have you made provision for a proper condensate drain system?
• Are the power supply cables of the right sizes?
• Are the main fuses of correct size?
• Does the compressed air delivery piping have the right dimensions

Finally, it is important to analyse these types of issues with regard to current as well as future requirements.It is then possible to design an installation offering sufficiently flexibility.
