Rhoss launches non-reversible water-source warmth pumps for high-temperature heating – pv journal International


Italy-based Rhoss has developed a cascaded water-source warmth pump that makes use of R1234ze or R515B as refrigerant. It is claimed to supply scorching water at a temperature of as much as 85 C.

Italian heating producer Rhoss has launched a non-reversible water-source warmth pump for business and industrial purposes.

The new product is reported to achieve scorching water temperatures of as much as 85 C and a seasonal coefficient of efficiency (SCOP) of as much as 5.04. “With screw inverter compressors and low GWP refrigerants similar to R1234ze or R515B, these models guarantee excessive efficiency with a discount in environmental influence,” the corporate stated in an announcement.

The producer says that the brand new FullFlow-I Boosted Eco warmth pumps symbolize a really perfect answer for business, tertiary, residential, and industrial purposes, as they’ll increase the recent water temperature “extra within the ordinary working limits of warmth pumps.”

The novel warmth pump is obtainable in seven variations with heating capacities from 410.4 kW to 1,000.5 kW. Their coefficient of efficiency ranges from 3.65 to three.83.

The smallest product measures 2,500 mm x 2,115 mm x 1,680 mm and weighs 2,065 kg, whereas the biggest model measures 3,155 mm x 2,115 mm x 1,680 mm and weighs 3,220 kg.

The warmth pump additionally has a show of the cooling circuit of excessive and low stress, an digital growth valve, and a master-slave management of as much as 4 models in parallel. It can work with screw compressors powered by an inverter and, in line with the producer, ensures good operation additionally in a stand-alone configuration, with the manufacturing of scorching water additionally with a low facet temperature on the supply of the water.

The Poker290 warmth pump has a heating capability of 47.4 kW and a cooling capability of 44.8 kW. The cascaded system can mix as much as 4 modules, with heating and cooling capacities of as much as 190.5 kW and 178.3 kW, respectively. The smallest unit measures 1,224 mm x 2,260 mm x 1,320 mm and weighs 670 kg, whereas the biggest measures 4,926 mm x 2,260 mm x 1,320 mm and weighs 2,680 kg.

The new gadget has a coefficient of efficiency (COP) of three.2. The temperature of the air supply may be from -20 to 40 C. The warmth pump can produce scorching water as much as 65 C with exterior air all the way down to -12 C. Its seasonal coefficient of efficiency (SCOP) for for heating water to 35 C varies between 3.81 and 4.19, whereas the SCOP for 55 C purposes varies from 3.20 to three.57.

It makes use of propane (R290) as a refrigerant, which has a world warming potential (GWP) of three. In an announcement, Rhoss stated that its new product means “it’s now attainable to supply fluorine-free refrigerant models for of latest installations, in addition to constructing repairs with integration or whole substitute of the prevailing heating system, together with gasoline boilers.

The Poker290 makes use of a double scroll compressor design that operates at 76dB(A), the equal of front room music.
