Superhydrophobic microchannel heat exchanger for heat pump performance enhancement

/in /by


Amid the global shift towards carbon neutrality, air-source heat pumps (ASHP) have emerged as efficient and environmentally beneficial to traditional boilers, attracting substantial attention in recent years. Contrary to the cooling process, where the condenser is inside, the heating process uses an indoor condenser and an outdoor evaporator in ASHPs.

Kaltra debuts water-cooled Easystream Evo chillers/heat pumps on R454b

/in /by


Designed to meet ambitious efficiency targets and equipped with rotary scroll compressors incorporating intermediate discharge valve (IDV) technology, Easystream Evo is the first series of Kaltra’s 4th generation chillers/reversible heat pumps. It offers cooling capacities from 50kW up to 250kW and up to 20% higher energy efficiency ratios (EER) in the standard version and up to 33% higher EER in its flagship version than the previous range. Even higher efficiencies can be reached in part-load operations.
