Global refrigeration technology provider Embraco has started mass production of the VESH variable speed compressor, its next-generation of the VES series that delivers up to 50 per cent energy savings.
The new compressor model allows refrigerator manufacturers to achieve the A level in the most stringent energy consumption regulations in the world, and is an upgrade of Embraco’s premium portfolio of highly energy efficient products for residential applications.
The level of energy efficiency achieved allows Embraco’s customers, the residential refrigerator manufacturers, to reach the highest classification (Level A) in the energy labels systems with the most stringent regulations in the world, such as Europe and Japan.
“VESH pushes the limits of energy savings in response to a market context in which this topic has become one of the main priorities for refrigeration appliances manufacturers and homeowners due to high energy prices, especially in Europe, where they are skyrocketing,” said Ricardo Bristotti, vice-president for the Home Appliances Business at Nidec Global Appliance.
The VES compressors family is the premium platform of Embraco’s portfolio, so besides efficiency, it also has the higher standards for acoustics, such as with its capability of running at 950 rpm in low demand, which makes it as silent as the ambient noise of a library, a relevant added value to the final consumer.
Because variable speed technology allows the VESH to adjust its running speed according to the demanded temperature, it also helps to improve food preservation, another feature valued by homeowners.
The Embraco VESH arrives on the market as the smallest variable speed compressors on this efficiency range – it weighs an average of 6.8kg and is only 144mm high.
“Miniaturisation of products is among the main drivers of our innovation process, for its many benefits,” added Bristotti.
“A smaller compressor allows more internal space inside the refrigerator cabinet, enables reduction of processes and materials used in the production flows, and optimises the transportation, contributing to environmental sustainability.”
The compressor achieves a maximum displacement of 11cc and 270W of cooling capacity, and is dual voltage (110V and 220V). In addition to residential applications, the VESH will also be suitable for some types of commercial refrigeration equipment.
It works with the natural refrigerant R600a, which has GWP close to zero and no impact on the ozone layer.
“The energy efficiency combined with the use of R600a is a significant contribution in terms of CO2 equivalent emissions reduction therefore, resulting in a more environmentally sustainable appliance to the final consumer,” he said.
VESH is strategically produced in Nidec Global Appliance’s plants in Austria and China.
“Our concern is to offer a better set of services to our local customers, while reducing environmental footprints on transportation, and avoiding disruptions caused by long logistics chains,” Bristotti concluded.
“The main target markets for this product are Japan and Europe, where the regulations regarding energy efficiency and noise are very strict.
“The market acceptance and understanding of the VESH features and benefits has surpassed our expectations so far, showing that the world is on a path toward sustainability that has no coming back.”
