Trane has released a rooftop air-to-air heat pump that can produce 14.5 to 37.4 kW of heat and 16.5 to 38.4 kW of cooling. The new device can be adapted to cold climate applications by adding additional heating sources, such as electric heaters or hot water radiators.

“Airfinity roof air-to-air units combine heating, cooling and ventilation in one package, making installation and operation easier,” the Irish manufacturer says on its website. “They are suitable for a wide range of applications, especially when low initial costs and easy installation are important.”

According to Trane, the new Airfinity S series is designed to be connected directly to the duct, with or without a ceiling edge.

The device is available in five different sizes, heating outputs 14.5 kW, 18.0 kW, 22.7 kW, 30.9 kW and 37.4 kW and cooling outputs 16.5 kW, 20.2 kW, 24.6 kW, 32 .9 kW, 38.4 kW. Their coefficient of performance (COP) is 3.82, 3.75, 3.72, 3.68 and 3.60.

The dimensions of the smallest heat pump are 1,310 mm x 2,062 mm x 1,170 mm and the weight is 393 kg. The dimensions of the largest are 1,723 mm x 2,655 mm x 1,832 mm and the weight is 697 kg.

The new device can be adapted to cold climate applications by adding additional heating sources, such as electric heaters or hot water radiators. “The intelligent Trane CH536 unit controller automatically manages multiple heat sources based on climate conditions and building load,” said Trane.

It uses a scroll compressor that works in a circular motion, unlike up and down reciprocating compressors. The units are designed to match fan rotation speed to building load and ventilation requirements, according to Trane. “This not only increases passenger comfort by preventing cold drafts, but can also reduce energy consumption by 60% over the life of the unit,” it added.

The device uses low global warming potential (GWP) R454B refrigerant.
