For refrigeration systems, the system with the highest coefficient of performance (COP) is R-717 (ammonia), yet it is toxic in sufficient quantities.
Increasingly, natural refrigerants * such as ammonia (R-717), carbon dioxide (R-744), and hydrocarbons (such as R-290 and R-1270) are being used to meet the demand for very low GWP refrigeration equipment.
Furthermore, a variety of refrigerants were investigated, including R-32, R-134a, R-404A, R-1234yf, R-717, and R-744.
Burning velocities and flammability limits in air have been measured for propylene (R-1270), propane (R-290), 1,1-difluoroethane (R-152a), ammonia (R-717), 1,1,1-trifluoroethane (R-143a), and difluoromethane (R-32).
Hasegawa SURELY[R] VZ/VZL reciprocating compressors are suitable for a wide range of applications in frozen food plants, Four, six and eight-cylinder and offer compressors for single-stage or two-stage operations are workhorses of the industry and are available for use with a wide range of refrigerants including R-717, R-22, R-507 and R-404A.
The existing R-717 refrigeration system was supplemented with a single screw compressor, and system design improvements were made to provide Fresh Brands with a higher degree of refrigeration system redundancy for the new and existing refrigerated areas.
If it does (for example, R-32 or R-717), then the burning velocity is independent of humidity; however, if there is less hydrogen (for example, any of the R-1234 flavors being proposed), then higher humidity will raise the burning velocity, but only up to the same sort of level as R-32 and R-717 (i.e., about 7 cm/s).
