This improved compressor efficiency has a bigger impact on reducing the carbon footprint of the chiller than the extremely low GWP value of HFO1234ze(E) of 6 versus 1300 for HFC134a. However, large low-speed machines are generally driven by large synchronous motors at fixed speeds. So the fitted curve of experiment has a little slope than simulation curve. Note that using the value of actual gas volumetric flow rate and discharge pressure, we can roughly determine the type of compressor appropriate for a particular application. In Plant Engineer's Reference Book (Second Edition), 2002. DTC compressor capacity can be maintained when replacing HFC134a with HFO1234ze(E) by switching the existing fluid module to the next frame size fluid module. It may seem that speed control would be the logical control method for reciprocating compressors. A slightly thicker vane with a softer spring is preferred for the compressor in study. For air-cooled chiller systems using HFO1234ze(E) a condenser redesign might be is required to prevent excessive pressure drop as a result of the 50% higher condenser volumetric flow rate at equal capacity that could negate the potential performance benefit of HFO1234ze(E). The swept volume of one piston can be calculated the following way.
