Difference between HVAC Absorption Chillers and Electric ... - Inst Tools

Absorption chillers have COP (coefficient of performance) of only 0.54–1.1 and it competes poorly with electric chillers (rotary compressor chillers). Electric chillers on other hand have COP from 1.0 ~ 8.0. Absorption HVAC chillers occupy approximately 50% more floor area than the equivalent electric chillers (vapor compression chillers).

Aug 03, 2021 Water-cooled chillers typically have lower condensing pressures than air-cooled chillers. This is because the water temperature is usually lower than the air temperature. If your condenser is operating at a lower pressure, then it will directly reflect and translate into lower operating costs or KW/TR (tons of cooling).
