Midea says its new Evox G3 outdoor heat pump ranges in size from 1.5 tonnes to 5 tonnes, with a coefficient of performance of 1.8. It features improved vapor injection technology and uses A2L as a refrigerant.
US-based heating specialist Midea has developed a new central duct outdoor heat pump for residential applications.
“This latest generation of the Evox series, with the Evox G3 Heat pump and Evox G3 Air Handling Unit (AHU) represents the future of electric, inverter heat pump technology as a solution for home heating and cooling upgrades, designed to deliver unparalleled heating/cooling comfort, performance and ease of installation throughout North America,” the manufacturer said in a statement.
It was claimed that the new product is suitable for all climates and is designed “to withstand severe winter temperatures.”
The Evox G3 The heat pump weighs 1.5 tons to 5 tons and has a coefficient of performance of 1.8. It is 36cm to 53cm wide, which the company says ensures easy deployment in challenging areas such as attics and basements. It can reportedly provide up to 100% heating power down to -25 C and operate “effectively” down to -30 C.
The heat pump also features improved vapor injection (EVI) technology and a multi-layer heat exchanger. These components make it possible to work with additional heat sources and achieve a high level of comfort, even in extremely cold weather conditions.
“Evox G3 you are also covered in summer, with a cooling efficiency of up to 19 SEER2, which can deliver energy savings of up to 32.5% compared to the conventional 14.3 SEER systems currently popular on the market,” the company said.
The EVI technology combines a two-stage refrigerant compression process with an intermediate injection of additional refrigerant vapor, which is said to improve overall performance and coefficient of performance.
“The injection of vapor refrigerant allows higher output temperatures and at the same time increases the operational range of the heat pump, ensuring excellent functionality even at sub-zero temperatures,” Midea said. “The multi-position installation configuration means contractors can store one stock unit and install it in six configurations.”
