During supermarket training, many technicians describe TXVs flooding evaporators and sending too much liquid through the coil. When the refrigerant doesn’t boil off as designed, heat transfer changes, airflow is affected, and system performance starts to shift in ways that aren’t always obvious from the outside.
• How a stuck-open expansion valve drops coil temperature
• Why ice formation reduces airflow and heat transfer
• Compound effects of low vs high superheat
• How floodback leads to compressor and oil issues
• Key considerations for identifying flooded coil symptoms
Understanding how evaporator conditions influence the entire system helps technicians troubleshoot with accuracy and confidence every time.
