Abstract
This paper provides 84 two-phase and 66 vapor phase PvTx measurements for binary blends comprising difluoromethane (R32) and cis-1,3,3,3-tetrafluoroprop-1-ene (R1234ze(Z)). The data are for seven i...
Highlights
Many hydrofluorocarbon (HFC) refrigerants are potent greenhouse gases with increasingly stringent restrictions being placed on their productions and uses.[1,2] As a result, the heating, ventilating, air conditioning, and refrigeration (HVAC&R) industry is increasingly being forced to actively seek low global warming potential (GWP) alternatives to more conventional HFC working fluids.McLinden et al.[3,4] recently conducted exhaustive searches and analyses of a publicly available database containing more than 60 million chemical substances for possible applications as low GWP working fluids in HVAC&R applications
The present paper expands the authors’ work by presenting 150 PvTx measurements for binary blends consisting of difluoromethane (R32) and cis-1,3,3,3-tetrafluoroprop-1-ene (R1234ze(Z)) both in the two-phase and superheated vapor regions using an isochoric test cell

Summary
Many hydrofluorocarbon (HFC) refrigerants are potent greenhouse gases with increasingly stringent restrictions being placed on their productions and uses.[1,2] As a result, the heating, ventilating, air conditioning, and refrigeration (HVAC&R) industry is increasingly being forced to actively seek low global warming potential (GWP) alternatives to more conventional HFC working fluids. The present paper expands the authors’ work by presenting 150 PvTx measurements for binary blends consisting of difluoromethane (R32) and cis-1,3,3,3-tetrafluoroprop-1-ene (R1234ze(Z)) both in the two-phase and superheated vapor regions using an isochoric test cell. The measurement procedure consisted of allowing the thermostatic bath temperature to stabilize at the desired test temperature, after which a circulating pump within the isochoric cell mixed the refrigerant sample for 15 min. The procedure was repeated for all of the desired temperature levels
