This unit uses an innovative, two-step evaporator and absorber cycle that is more efficient and more reliable than conventional designs. The flexibility combined with a wide operating envelope is optimally suited for commercial cooling and industrial process applications. Our world-class engineering and service organization helps simplify startup and chiller operation over the life of the system.

Benefits

OPTIMAL EFFICIENCY

The YORK® YHAU-C Singe-effect, Steam Absorption Chiller uses an innovative, two-step evaporator and absorber design for enhanced efficiency.

FLEXIBLE DESIGN

This unit is suited for a variety of steam pressures found in CHP systems, commercial cooling and industrial process applications.

LOWER COST OF OWNERSHIP

Our world-class engineering and service teams reduce the cost of ownership by simplifying the operating cycle and deliver worry-free peace of mind.

Features

• Innovative YORK® two-step evaporator and absorber design enhances absorption of the refrigerant into the concentrated solution, reducing overall pressure and risks of crystallization.
• Solution plate heat exchanger optimizes efficiency by enabling effective heat transfer between the diluted and the concentrated lithium-bromide solutions.
• Control center with graphical, animated LCD display offers present and past operational status, data recording and chiller safeties accessible at a touch.

• Lower pressure steam into the generator can be used to drive the absorption cycle for higher system efficiency.
• Tubes made with deoxidized, low-phosphorus (DLP) copper protect against corrosion cracking. Water boxes coated with epoxy paint deliver corrosion resistance.
• Isolation valves on the suction and discharge of the solution and refrigerant pumps allow quick and easy servicing of pumps, which typically have a 60,000-hour life.

Two-step Evaporator and Absorber

YORK® YHAU-C Single-effect, Steam Absorption Chillers are uniquely designed with a two-step evaporator that has two pressure levels to divide the absorption process. The chilled water flows in tubes through the two evaporators while a concentrated lithium bromide solution is distilled in the absorber shell-side in the opposite direction. This reduces the solution concentration and overall pressure, making the unit more efficient and reliable than conventional absorption chillers.

Falling Film Generator

The falling-film generator design provides superior heat transfer compared to a conventional, flooded generator. This design also reduces the required amount of lithium-bromide solution to be circulated, decreasing start-up time from a cold start. Stainless steel tubes are adopted to prevent stress corrosion cracking and intermediate tube supports reinforce and extend unit life.
