Model YVAA Air Cooled Screw Compressor Liquid Chillers. Duty: 530 kW to 1,750 kW
YORK YVAA model air-cooled chillers provide superior performance. Higher efficiency heat exchangers coupled with variable speed operation and smart controls elevate the system efficiency to a whole new level. The resulting benefit from YVAA chillers is much greater than the sum of its parts.
YVAA air-cooled chillers are completely assembled with all interconnecting refrigerant piping and internal wiring, ready for field installation. The unit is pressure tested, evacuated, and fully factory charged with refrigerant R134a and oil in each of the independent refrigerant circuits. After assembly, an operational test is performed with water flowing through the evaporator to ensure that each refrigerant circuit operates correctly.
The YVAA chiller’s energy performance can exceed that of older chillers by as much as 50 percent, and competitive chillers by up to 25 percent. Lower energy consumption also means lower greenhouse gas emissions from the power plant. Specific benefits include:
- Offering flexible energy consumption, the YVAA chiller can be configured to offer design efficiency up to 11.6 EER, and an integrated part load value (IPLV) up to 19.8 EER.
- The chiller uses HFC-134a refrigerant, which has no phase-out date and an ozone-depletion potential of zero.
- Fewer joints and potential leak points keep the refrigerant inside the chiller.
- A proprietary falling-film evaporator and advanced microchannel condenser coil reduce the refrigerant charge by as much as 15 percent.
- Installation of the YVAA chiller gives building owners the opportunity to earn points in the Leadership in Energy and Environmental Design (LEED®) green-building certification programs.
