Joachim Maul, Director of R&D at ait-deutschland, presents on LWD R290 heat pumps, which can reach flow temperatures of up to 70°C. Water temperatures of 62°C at -20°C are possible without an additional electrical heater. The heat pump is suitable for renovation markets. According to Maul, R290 is a good refrigerant for outdoor air/water heat pumps and provides advantages of high temperatures at low ambient temperatures.

About the speaker(s)

Joachim Maul

 

Joachim has studied mechanical engineering, specialized in fluid- and thermodynamics. He received his Ph.D in 1994 with a thesis on the behavior of chemical reactions on the surface of ceramic tiles during the re-entry of a capsule.

Starting after university as a R&D Manager for volume flow measurement techniques, his life with refrigerant circuits begins in 2000 with Rittal, where he was responsible from technical side for cabinet coolers and heaters. During that time he developed cabinet air conditioners with CO₂ as a refrigerant. At the beginning of 2010 he joined Alpha-Innotec (now called ait-deutschland) as the Director R&D. In the last few years one of his important projects was the successful development and market introduction of a new generation of R290 heat pumps. Several patents and publications are a result of his work in different areas. Furthermore, Joachim is a member of several associations and different working groups especially for heat pumps.
