Performance Analysis of Transcritical CO2 and R1234yf High Temperature Heat Pump Water Heater at Low Ambient Temperature

Performance Analysis of Transcritical CO2 and R1234yf High Temperature Heat Pump Water Heater at Low Ambient Temperature

In heat pumps, the use of environmentally friendly refrigerants can reduce damage to the ozone layer. Under the condition of low ambient temperature, based on the existing heat pump system, the CO2 transcritical cycle and mechanical subcooling were adopted. An R1234yf/CO2 mechanical subcooling heat...
