Performance Measurement of R32 in Vapor Injection Heat Pump System
As global warming has raised more critical concerns in recent years, refrigerants with high global warming potentials (GWP) are facing the challenges of being phased out. R410A, with a GWP of 2,088, has been widely used in residential air-conditioning and heat pump systems. A potential substitute for R410A is R32, which has a GWP of 675. This paper investigates the performance difference of R41...

متن کاملPerformance Investigation of Refrigerant Vapor-Injection Technique for Residential Heat Pump Systems
An 11 kW R410A heat pump system with a two-stage vapor-injected scroll compressor has been developed and tested. A conventional heat pump system with a scroll compressor having the same displacement volume to the vapor-injected scroll compressor has been tested under the same conditions to serve as a baseline. The vaporinjected scroll compressor has been tested with the cycle options of both fl...

متن کاملNumerical Simulation of the Freezing Process in Geothermal Boreholes Using Solar Heat Injection
Ground thermal energy as a clean and sustainable energy source has received significant attention lately. Several strategies and hybrid configurations have been proposed to harvest geothermal energy for air conditioning and industrial purposes. The possibility of moist soil freezing in the vicinity of borehole tubes is known to be the source of several benefits and difficulties. The high storag...
