YORK YVAA chiller is an air-cooled, variable-speed screw chiller celebrated for its exceptional efficiency and performance. This modern chiller incorporates advanced technologies to deliver higher cooling capacity per unit of energy.
Below, we explore the YVAA air-cooled chiller key components, how its efficiency metrics compare to those of other chillers, its applications in real-world scenarios, and maintenance tips to keep it running at peak efficiency.
The YVAA chiller owes its exceptional efficiency to the seamless integration of advanced components, each designed to optimize performance at every stage of the cooling cycle.
At the heart of the YVAA is a Johnson Controls-engineered twin-screw compressor driven by a liquid-cooled variable-speed drive. This allows smooth modulation from full load down to light-load conditions, cutting energy use by 15-25% annually.
The integrated Variable Volume Index (VI) technology adjusts the internal compression ratio in real time, preventing over-compression and maintaining high part-load efficiency. Each compressor undergoes rigorous end-of-line testing for proven reliability.
The YVAA incorporates a hybrid falling‑film evaporator and microchannel condenser coils as standard features. These heat‑exchange technologies increase thermal efficiency and lower refrigeration load.
The liquid‑cooled VSD is integral to achieving both energy savings and reduced sound levels in the YVAA system.
YVAA chillers are performance‑tested in AHRI‑certified labs and offer customizable options to match capacity, efficiency, sound, and footprint for specific applications.
YVAA chiller sets strong benchmarks in key efficiency metrics, which underline its superior performance in both full and part‑load conditions.
With an Integrated Part Load Value (IPLV) of up to 21.3 EER, YORK YVAA chiller ranks among the most efficient air-cooled screw chillers in the market. Unlike fixed-speed screw chillers, which often struggle to maintain efficiency when operating below peak load, YVAA’s variable-speed drive allows precise modulation to match demand, significantly reducing wasted energy.
The YVAA can deliver 15–25% annual energy savings compared to legacy systems and save energy when replacing older chillers. In certain applications, where full VSD and optimization features are used, energy cost reductions of up to 50% have been recorded.
YVAA’s advanced Variable Volume Index (VI) technology optimizes the internal compression ratio based on real-time conditions, preventing over-compression and ensuring superior performance across varying loads. This gives it a measurable edge over traditional fixed-speed designs, which operate less efficiently under part-load scenarios.
Additionally, the YVAA’s broad ambient operating range, from –10°F to 131°F, enhances its adaptability for diverse climates.
YVAA chiller’s design and performance credentials make it suitable for a wide range of applications where efficiency, reliability, and flexibility matter.
High‑rise office towers, shopping complexes, universities, or hospitals can benefit from YVAA’s high efficiency, compact footprint, and customizable options to reduce energy costs and meet sustainability goals. The absence of a cooling‑tower requirement simplifies installation and maintenance.
Critical facilities such as server farms require continuous, high‑reliability cooling. The YVAA’s variable‑speed drive, fast restart capability, and broad ambient range make it a strong option for data centers.
Manufacturing plants, pharmaceutical production, food processing, and other industrial operations benefit from YVAA chiller’s durable screw compressor design, customizable capacity, and robust performance. The flexible ambient range and efficient modulation make the YVAA suitable for fluctuating loads typical in industrial process cooling.
To sustain the YVAA chiller’s high performance, regular maintenance and proactive care are essential.
