Condenser vs Evaporator: RFQ Information

Condensers and evaporators can look similar in factory photographs, but they perform different functions. Correct project classification starts with the working medium, required duty and entering and leaving conditions—not appearance alone.

Condenser project inputs

A condenser rejects heat while the refrigerant or process medium condenses. Provide refrigerant or medium, condensing conditions, required heat rejection, airflow or cooling-side data and the installation envelope.

  • Refrigerant or working medium
  • Condensing and ambient conditions
  • Required heat-rejection duty
  • Airflow or cooling-side flow

Evaporator project inputs

An evaporator absorbs heat while the refrigerant evaporates. Provide cooling duty, refrigerant, evaporating condition, entering and leaving air or fluid data, airflow and any defrost or drainage requirement.

  • Cooling duty
  • Refrigerant and evaporating condition
  • Entering and leaving air or fluid data
  • Defrost, coating or drainage needs

Inputs common to both

Both project types require envelope, circuiting, connections, materials, allowable pressure drop, testing, quantity and documentation requirements.

  • Overall dimensions and mounting
  • Circuit and connection layout
  • Materials and coating
  • Testing, packing and quantity

Frequently asked questions

Project questions

Can a photograph confirm whether a coil is a condenser or evaporator?

Not reliably. The function and operating data must be confirmed before the product is classified for quotation.

Do condenser and evaporator quotations use the same inputs?

They share mechanical inputs, but the thermal and operating data differ because one rejects heat and the other absorbs heat.
