Berkah Fajar T.K - R-22 Freezer

Abstract

R-22 has a relatively high nature of global warming, the use of R-22 must be stopped. Refrigerant r290 / R290 is the type of refrigerant recommended by many experts to replace R-22 because the global warming properties of R-290 are much lower than R-22. In this research, cooling capacity, mass flow rate, the power consumed, and COP were evaluated. The freezer machine used has a capacity of 1 PK, redesigned by adding ducting to the condenser channel. Overall results, R290 can be a better substitute for the R22 in real applications due to excellent ambient, thermo-physical properties, and energy-saving performance.
