Proven Energy Savings with the APR Control (Manufacturer Testing)

Stop Paying for Inefficient HVAC Operation

Overview

Most HVAC systems operate at part-load conditions the majority of the time. Unfortunately, traditional system designs often force equipment to run inefficiently during these periods, driving up energy costs while reducing overall system performance

Because of this, reducing energy use in HVAC systems is one of the most effective ways to lower operating costs and improve system performance. The APR Control has long been a trusted solution for both new equipment and retrofit applications by helping systems better match capacity to real-time building load, especially during part-load conditions where most HVAC systems operate.

Now, real-world testing conducted by a leading HVAC equipment manufacturer provides clear, measurable proof of APR Control’s energy-saving performance.

Independently Verified Performance That Drives ROI

Rawal Devices has long demonstrated that the APR Control’s ability to load-match improves efficiency by reducing compressor lift and enhancing evaporator performance. Until recently, however, independent testing data had been limited.

To validate these performance claims, a major HVAC manufacturer evaluated the APR Control as a factory-installed solution. The goal was simple: determine that the APR Control delivers meaningful energy savings, while improving system performance at part load.

The results confirm what contractors, OEMs, and facility owners have already experienced in the field: APR Control helps systems run smarter, longer, and more efficiently.

Testing Conditions

Evaluation was performed in a controlled testing laboratory environment. Under low load conditions, energy consumption was measured on the first-stage compressor and compared between units operating:

  • With APR Control

  • Without APR Control

To establish a baseline, results were also compared against the same unit operating at full-load AHRI design conditions.

Real-World Results

APR Control delivers 16% energy savings by reducing first-stage compressor watt consumption

The APR Control delivered measurable, immediate efficiency improvements:

  • 16% lower power consumption at part load
    • APR Control: 2,153 watts
    • Without APR Control: 2,503 watts

These findings demonstrate APR Control’s ability to deliver meaningful energy savings while maintaining system performance and humidity control.

Why Choose the APR Control

The APR Control is a proven solution that allows HVAC manufacturers, contractors, and building owners deliver greater value to their customers by:

✔ Lowering utility costs via less energy consumption & compressor workload

✔ Improving part-load performance where systems operate most

✔ Supporting energy code compliance and sustainability goals

✔ Enhancing system performance without major design changes
