The systems use propane as a coolant and vary in capacity from 40 kW to 410 kW. Their coefficient of performance reaches up to 3.88.
Rinnai Applied, a unit of Japanese heating solutions provider Rinnai Corp, has launched a new line of air-to-water heat pumps for commercial and industrial applications.
“Flexibility and system versatility are key features of the R290 commercial and industrial heat pump range, with the addition of smart control logic that can manage up to six units, five of which are controlled by a master unit. This arrangement prioritizes system performance and minimizes waste,” the manufacturer said in a statement.
The systems vary in capacity from 40 kW to 140 kW and use propane (R290) as a coolant.
The smallest model measures 1,973mm x 1,099mm x 2,592mm and contains two compressors, while the largest model measures 2,444mm x 2,240mm x 6,210mm and contains six compressors. The tank capacity is 150 liters for the smallest unit and 300 liters for the largest.
According to Rinnai, the new heat pumps offer an energy efficiency ratio (EER) of 3.15 to 3.49 and a seasonal energy efficiency ratio (SEER) of 4.36 to 4.93.
The coefficient of performance (COP) reportedly ranges from 3.54 to 3.88, with a seasonal coefficient of performance (SCOP) between 3.99 and 4.30. The noise level is between 86 dB(A) and 95 dB(A).
The units can deliver supply water temperatures of up to 75°C, the company said.
“Whether you are upgrading an existing system or planning a new build, these units are ready to provide comfort, compliance and cost savings,” it added.
