The YORK YHAU-CGN Direct Fired Absorption Chiller uses an innovative two-step evaporator-absorber design with a parallel flow cycle that ensures the lowest lithium-bromide solution concentration, offering the best protection from crystallization. This enables increased reliability compared to conventional absorption designs. The unit delivers a high real-world energy efficiency with a COP (coefficient of performance) of 1.2 - 1.27 based on the higher heating value of natural gas.
The unit can also be configured as an absorption heat pump, delivering a hot water temperature of up to 194 °F, well-suited for comfort and process heating applications. Because the heating COP is 1.7, the chiller is approximately 70% more efficient than a standard boiler, providing cost savings for users.
The YHAU-CGN Direct Fired Absorption Chiller offers five different modes of operation and accommodates a wide range of applications like commercial comfort cooling, process cooling, and large district cooling. The unit has a wide range of entering condenser water temperatures and leaving chilled water temperatures compared to other conventional chiller-heaters units.
