heat pump efficiency outside temperature graph

The reason for heat transfer enhancement invoked in is fluid mixing by ultrasonic vibrations that provided fresh water to the heat transfer surface increasing the temperature gradient. Wave and flow patterns can be predicted precisely which could be a basis of a future tool for the optimization of vibrating heat exchangers 13.

The graph above shows the number of heating degree days for different base temperatures in a few of the worlds cities.

. It provides an upper limit on the efficiency that any classical thermodynamic engine can achieve during the conversion of heat into work or conversely the efficiency of a refrigeration system in creating a temperature. Its useful because it shows how direct the relation is between heat gain and heat loss. The Carnot cycle is a theoretical ideal thermodynamic cycle proposed by French physicist Sadi Carnot in 1824 and expanded upon by others in the 1830s and 1840s. The graph below it shows the temperature flow curve for a sample heater in this case one with an output of 180000 Btu.

Determine how many fixtures or appliances will be operated at the same time add up their flow rates then look at the curve to determine if that unit will meet the homes needs. A heating degree day is a measure of the difference between inside and outside temperatures.
