York S1-363-90016-701 4-Tube Heat Exchanger

Thermostatic expansion valves are an integral part of your refrigeration unit. They are responsible for ensuring the right dosage of refrigerant is entering the cooling coil to ensure maximum efficiency in the air conditioning of the system.    These special expansion valves come with a temperature sensor that is mounted at the end of the evaporator coil. They incorporate signals from this sensor to maintain the required temperature of the HVAC system. The thermostatic expansion valve works like a precision device that can regulate the measurements of the liquid refrigerant that flows into the evaporator of your system. This regulation in the flow of the refrigerant is essential to prevent the reverse flow of the refrigerant into the compressor of your system.    Through this mechanism, the thermostatic expansion valve successfully separates the high and low pressure sides of the refrigeration/air conditioning system. The liquid refrigerant enters the expansion ...

Inspect coils and tubing for corrosion or leaks regularly. Clean dust and debris buildup to maintain efficient heat transfer. Ensure secure connections and proper airflow during operation. Routine checks can prevent performance issues and overheating.

• Tube fouling causing reduced heat transfer.
• Corrosion or pitting in tubing.
• Refrigerant or fluid leaks at joints.
• Blocked airflow leading to uneven heating.
• Pressure drop or system inefficiency.
• Reduced performance under high load conditions.
