WebGenerally speaking when it comes to refrigerants, chillers are divided into two categories: low/medium (L/M) and medium/high (M/H) pressure. L/M pressure chillers can benefit …
Webpressure, lower compressor discharge temperature, slightly lower compressor power consumption, and a higher compressor high-low pressure ratio. Temperature glide for ternary mixture, for both evaporator and condenser, was clearly evident, but not as pronounced as expected because of the pressure drop (and thus the temperature drop) … Web2 de nov. de 2003 · Because of the higher operating pressures, the high- and low-pressure control settings must be higher than those encountered on R-22 systems. The recommended high-pressure control settings are a cut-out pressure of 610 psig and a cut-in pressure of approximately 500 psig.
WebL/M pressure chillers can benefit from the use of pure HFOs (R1233zd and R1234ze), resulting in a GWP close to zero. The flammability penalty is very low and manageable, especially for systems installed outdoors or in machine rooms. We can expect that for the short-to-medium term, this type of systems will adopt ultra-low GWP refrigerants. WebBall pressure temperature. N/A.
