How Absorption Chilling Systems Work
Unlike conventional chillers, absorption chillers use waste heat from other processes to chill water and distribute it for HVAC needs.

Products
- Coefficient of performance (COP) of 1.23 based on lower heating value (LHV) with a turndown ratio from 100% to 25%.
- Ambient temperature range of 5°C/41°F to 40°C/104°F with 10-90% relative humidity.
- The space-efficient design of the unit simplifies installation through forklift loading or via an emergency/service elevator.
- Innovative YORK® two-step evaporator and absorber design enhances absorption of the refrigerant into the concentrated solution, reducing overall pressure
- Variable driving heat sources, such as jacket water from a gas engine, low- to high-pressure steam, direct-fired or exhaust gas
- Two types of YHAP-C absorption heat pumps are available: a heat amplifier (Type I) driven by high-temperature, and heat transformer (Type II) driven by medium-temperature
- Two-step evaporator and absorber design enhances absorption of the refrigerant into the concentrated solution, reducing overall pressure
- Parallel flow cycle enables lower lithium bromide solution concentrations, reducing crystallization risk and the potential for corrosion
- Variable-frequency drive (VFD) solution pump provides superior part-load performance to reduce gas/oil consumption versus constant speed pumps
- Innovative YORK® two-step evaporator and absorber design enhances absorption of the refrigerant into the concentrated solution, reducing overall pressure
- Lower temperature hot water source into the generator can be used to drive the absorption cycle for higher system efficiency
