Trouble Shooting a Faulty Refrigeration Circuit-Danfoss
How to Troubleshoot HVAC Faulty Refrigeration Circuit
Smart troubleshooting of HVAC problems and malfunctions is a technique how a HVAC technician thinks very sharply and shoot skilled way. Quick trouble shoot depends on fault finding techniques rather than the difficulty the fault. Sometimes very simple problem kills a long-span of technician time, reversely tactful technician solves the critical malfunction very quickly.
Today, we will focus our short troubleshooting discussion on some common technique to find the faulty part on HVAC refrigeration circuit system.
The total Heating Ventilating & Air Conditioning system is a vast system, and it contains various types lots of equipment. An HVAC system consists of compressors, motors, furnaces, cooling systems, air conditioner, air handling systems, ductwork systems, heating systems, humidity controlling systems, fan connected networks, different types of controllers and vast electrical & mechanical systems.
How Think to Troubleshoot HVAC Problems and Malfunctions As a Pro.
An HVAC professional first try to categorize and subcategorize the problem and locate the faulty or malfunction part of the system, then shoots.
Example- when a technician face a problem, he think to recognize is it electrical problem or mechanical, is not functioning the main equipment or controlling system, which area of the system is not working actually, etc.
Following the above algorithm it makes easy to find out the malfunction part shortly and troubleshoot promptly.
Do better diagnosis- focusing verification on power line; power supply panels chronologically checking- Circuit Breaker is not tripped; heating/ventilating/cooling system’s own breaker or fuses are not tripped or burn; wait until complete the breaker or relay waiting (10 second) times; reset the power system; check the thermoset position; if there is battery, check battery is still alive and reset battery power.
Guide to Find Fault Location In Refrigeration Circuits With Hermetic Compressors
Be a professional HVAC technician following the DANFOSS trouble shooting guide to find out the faulty part in refrigeration circuits with hermetic compressor were briefly discussed on the topics:
- When compressor or system does not run or get start;
- The compressor or system runs, but with reduced refrigeration capacity;
- System running but power consumption too high
- Noisy systems, etc.
