(2022) considered marginal emissions from electricity generation, domestic natural gas combustion, and refrigerant leaks in the heating system. A bottom-up approach was employed to investigate the emissions reduction potential of integrating high-temperature heat pump technologies into the food and ...
This is because CO2 is an environmentally friendly refrigerant as compared to hydrofluorocarbon refrigerants, and because water can be heated to high temperatures by employing a CO2 transcritical cycle. HPUs installed in Japanese residences are characterized by the installation of large-capacity STs to...

The cycle function is such that the portion of the expenditure being driven through the generator undergoes a direct thermodynamic cycle, which allows the rest of the mass flow of the refrigerant to complete the inverse thermodynamic cycle of a refrigeration machine. Pressurization starts from the ...
