Pumped Glycol Energy Recovery | Efficiency vs. Effectiveness

Topic: High Performance Run Around Energy Recovery Systems Guest Blogger: Rudolf Zaengerle, Ph. D. Konvekta USA, Inc There is some confusion about the terms ‘efficiency’ and ‘effectiveness’:  Efficiency ASHRAE defines ‘temperature transfer efficiency’ (or sometimes ‘enthalpy transfer efficiency’ if enthalpy is used instead of temperature) as follows: μT = (TE1 – TE2) / (TE1 –… Read more »

Ask Rick: Pumped Glycol Systems | Does Air in the Glycol impact performance?

Konvekta Pumpd Glycol Pumping Package

Q.  I have some questions about pumped glycol systems.  What happens if all the entrapped air is not removed from the glycol?   Should a closed loop have auto bleed? A.   Air bubbles entrapped in the glycol circuit are very detrimental to the thermal performance of the energy recovery system.  It causes the heat transfer… Read more »
