Governing Formula:
THR (BTU/hr) = Evaporator Capacity (BTU/hr) + Compressor Heat (kW ร— 3412); THR โ‰ˆ TR ร— 15,000 BTU/hr
Pune Field Notes & Environmental Standards:

Crucial for air-cooled and water-cooled condenser sizing to avoid high discharge pressure trips during peak summer.

Technical Engineering Guide & Field Diagnostic Practices

The condenser must reject both the heat absorbed in the evaporator and the electrical compression work done by the compressor motor. Accurate THR calculation prevents condenser undersizing and thermal trips.
