Caravan RV Manufacturer Chooses Boyard Inverter Compressors for Noise and Energy Reduction

The global leader in air conditioning units for caravans and recreational vehicles has deployed Boyard’s inverter compressors with variable speed in their units, significantly reducing noise, energy consumption, and costs.

Background

The global leader of vehicle air conditioners spacialized in designing and manufacturing roof-top A/C units for caravans and recreational vehicles (RVs).

In recent years, the demand for recreational vehicles (RVs) has grown significantly as consumers spend more time outdoors or traveling as ‘nomads.’ These RVs are often equipped with advanced technology, such as solar-powered air conditioners and hot water generators, to provide maximum comfort and convenience for passengers regardless of outdoor conditions.

Traditionally, RV air conditioning units had used basic single-cylinder, fixed-speed compressors to keep the unit cost competitive against other A/C OEMs. However, with increasing demand for energy conservation and environmental preservation, single-cylinder compressors can no longer meet the market’s demand due to its limited capability.

The OEM, the global leader of RV A/C units, turned to Boyard for energy-efficient and quiet compressors for their next-generation A/C units.

Challenges

Noise, Vibration, Harshness (NVH)

End-users of the A/C manufacturer had harshly complained that their previous unit with a single-cylinder compressor produced too much noise and vibration, affecting sleep quality. When the compressor’s rotating speed was low, it generated higher vibration.

Requirements for Higher COP

The original A/C unit was not energy efficient and wasted significant energy. The A/C OEM urgently needed to improve the unit’s energy efficiency and reduce energy consumption to align with the trend of energy and carbon reduction by optimizing the system design.

Lower Cost, but Differentiate Products

The RV A/C OEM needed to reduce costs to compete effectively in the increasingly competitive mobile air conditioning market. At the same time, the OEM wanted to avoid solely relying on cost reduction to maintain market share. They aimed to develop differentiated A/C units to grow their market share or enter new market segments for growth.

Therefore, in the new generation of their A/C unit, the OEM set the following requirements:

  • Deploy compressors with high COP for higher energy savings
  • Reduce noise and vibration to increase comfort for passengers
  • Increase reliability and reduce the failure rate of the A/C unit

Solution

Boyard collaborated with the OEM to develop a new horizontal, variable-frequency compressor with dual cylinders. The new JFSA116Z220 compressor met the OEM’s requirements to stay abreast of RV market demand. This variable-speed technology automatically adjusts the compressor’s operating frequency on demand, avoiding unnecessary energy waste and meeting the requirements for energy efficiency and reduced noise and vibration.

Benefits of Boyard JFSA116Z220 Compressor

Energy-saving

The new compressor with inverter technology and dual cylinders automatically adjusts its operating speed under different conditions, achieving higher energy efficiency and ultimately saving significant energy. When running at low frequencies, the compressor’s efficiency was significantly improved. When the variable frequency compressor operates continuously, it has roughly 30% better energy-saving effect than the on/off operation of a fixed-speed compressor.

Noise reduction

Compared to traditional single-cylinder compressors, the dual-cylinder variable frequency compressor significantly reduces noise. Boyard’s dual-cylinder compressors have optimized structural design and materials, reducing noise and vibration compared to alternative compressors on the market.

Improved reliability

Boyard’s dual-cylinder design and variable-frequency technology enable the compressors to maintain stable performance and reduce wear and tear throughout long-term operation. This results in overall improvements in reliability. Through rigorous testing and optimizations, Boyard ensures the compressors maintain high efficiency and reliable performance across various operating conditions.

Technological innovation

Currently, most dual-cylinder variable frequency compressors on the market are vertical. For over two decades, Boyard has been a pioneer of horizontal compressors, which have structural and mechanical design challenges for oil returns, etc. Boyard further innovated horizontal compressors with dual rotor, DC drive, and variable frequency technology.
