Heat recovery from waste heat


There are many potential sources of unused heat in the industry, as well as in many areas of energy that are left unused every day, as their temperature between 20 ° C and 45 ° C is virtually unusable for high temperature heating systems. On the other hand, older heat pump systems were limited by the temperature of the heat source at 20 ºC and at the outlet temperature of up to 60 ºC.

New compressor technology has a extended working envelope in the high temperature field. It is noteworthy that not only a higher outlet temperature can be achieved, but above all, a shift in the COP efficiency is possible, which at a water outlet temperature of 80 ° C can also be 4.2 ~ 4.5, as long as the temperature of the source moves between 35 ºC and 40 ºC.
