what does HIGH COMPRESSOR LIFT mean? HVAC/R

17/02/2010· The relationship can be summarized as: lower ECWT = lower lift = lower compressor work = lower energy usage In comfortcooling applications, ambient weather conditions often allow facility owners to take advantage of ECWT as low as 50˚ (at AHRI conditions) The capability to use lower ECWT significantly improves chiller efficiency In fact, greater chiller efficiency can be achieved by

Compressor lift is compressor pressure Lift = pressureI would say pressure difference to be more exact, suction and discharge People often talk about lift in the same sense as cycle work, power and ensome says its the difference of the evap and condensser temperature???Therein lies the confusion Inside the saturation curve, the temperature at a given pressure is constant ie Know the pressure, you know the temi reviewed the PH diagram of the system and noticed that the discharge superheat is quite high My assumption: Since the discharge superheat is hiCompressor lift is simply the saturated condensing pressure minus the saturated evaporator temperature It's a mostly useless term, since almost noUsually this works the other way around Because of a warmer outdoor air temp or condenser water temp, you get a high condensing temp, which requirHere is another explanation: Lift (or head pressure) is the difference between condenser refrigerant pressure and evaporator refrigerant pressureHigh Vibration of reciprocating compressor13/11/2005Big Air Compressor20/06/2005查看更多结果
