Carrier, a US-based heating solutions provider, has introduced a new line of heat pumps from 4 to 14 kW with a coefficient of performance up to 4.90. The system uses propane as a coolant and can reportedly reach a supply water temperature of 75°C.
Carrier has launched a new range of air-to-water heat pumps for residential and commercial applications.
“This monoblock offers an impressive price-performance ratio, has a compact footprint and low refrigerant charge, further minimizing its environmental impact,” the manufacturer said on its Linkedin account, noting that the new product is designed for installation outdoors in an open area.
The monobloc AquaSnap 30 AWH-P system uses propane (R290) as a refrigerant and is available in eight versions – 6 single-phase models and 2 three-phase models – with a rated power ranging from 4 kW to 14 kW and a coefficient of performance (COP) ranging from 4.90 to 4.80.
The smallest product measures 946 mm x 560 mm x 927 mm and has a weight of 79.3 kg, with a noise level of db(A) 49. The largest system has dimensions of 946 mm x 560 mm x 1,375 mm, weighs 129 .3 kg, and has a noise level of db(A) 54.
In heating mode, the heat pumps can reportedly operate at an outdoor air temperature of -20 C, while for cooling they can operate up to 46 C. According to the manufacturer, the leaving water temperature can reach up to 75 °C.
“AquaSnap 30AWH-P can be connected to up to 4 units for heating and cooling requirements in light commercial applications,” Carrier explains. “Each of the units can individually meet the requirements of the space in which it is installed.”
The heat pumps also have a built-in Gateway with which living comfort can be managed remotely via the Carrier Comfort Management App.
“The 30AWH-P range delivers high performance and is compatible with low to medium temperature emitters such as underfloor heating, fan coil units, hydronic cassettes, radiators and mixed installations,” the company said. “And to high-temperature radiators for renovation applications such as replacing boilers.”
