Energy-Efficient Makeup Air Units

Topic: Energy-Efficient Makeup Air Units Guest Blogger: Hugh Crowther, P.ENG., Ashrae Member Unless you live in paradise, delivering makeup air to most buildings is expensive.  Table 1 shows the amount of work it takes to heat and cool air (based on Chicago  conditions) for a standard rooftop unit (a unit that recirculates air with typical… Read more »

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 »
