Tecnofreddo launches commercial R290 air-source heat pumps

The PERSEO line, with a COP of 3.5 in cooling mode and 4.0 in heating mode, is viable in colder regions, the company says. Italian manufacturer Tecnofreddo has launched a “new generation” line of commercial propane (R290) air-source heat pumps (ASHPs) called PERSEO, part of its ECO3 product series. Tecnofreddo touts “long experience” in R290 refrigeration. “R290 is a promising and cost competitive refrigerant for ASHPs with superior environmental protection credentials,” the company said in a statement. “It has substantial potential for use in such areas as supermarkets, hospitals and public buildings.” Air-source heat pump technology, added Tecnofreddo, “has improved in all areas and is these days a viable option even in colder regions.” One of the first end users to adopt the PERSEO has been British Johnson Matthey, a manufacturer of exhaust gas cleaning technology. Coordination for the Johnson Matthey project has been carried out Arriba Technologies, a Tecnofreddo collaborator based in the UK.  The PERSEO line employs a liquid/gas heat exchanger that increases the COP to 3.5 in cooling and 4.0 in heating. Models are capable of delivering 48°C (118.4°F) water in heating mode ...

Cooler Master shows off the MasterLiquid Dual Pump AIO – Cooling – News

Cooler Master is at Computex 2019 and is showing off a wide range of CPU coolers using different technologies. It has air coolers with heatpipes and vapour chambers embedded in the designs suiting various case sizes and TDP loads. However, it seems to have pushed the boat out further with its AiO coolers and is showing off one with a dual-pump, and another with a reservoir which has a whirlpool effect. The Cooler Master MasterLiquid Dual Pump AIO Design has an appealing design with RGB lighting and clean-lines, considering its more complex nature. In the CPU cooler block, as pictured, are dual pumps which are designed to work together by maximizing the flow rate and flow pressure of the coolant to the water block. It is claimed by Cooler Master that the enhanced flow rate and flow pressure of the coolant “will dissipate the CPU heat at a much faster rate compared to the traditional AIO liquid coolers”. Pricing and availability of the Cooler Master MasterLiquid Dual Pump AIO is yet to be finalised. Another head-turning design is the MasterLiquid Maker 240 New Edition. Cooler Master equips this design with a newly designed reservoir and pump that “creates a liqui...
