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. flip toss
