Heat pumping with R744 : the transcritical cycle As mentioned previously, the critical temperature of R744 is around 31°C. If ambient air is used to cool on the high pressure side and is available at 35°C for example, it will not be possible to condense the refrigerant.

Heat pump (HP) is one of the most energy efficient tools for address heating and possibly cooling needs in buildings. Growing environmental concerns over conventional HP refrigerants, chlorofluorocarbons (CFCs), and hydrofluorocarbons (HFCs) have forced legislators and researchers to look for alternatives. As such, carbon dioxide (R744/CO2) has come to light due to its low global warming

"There are already some manufacturers in China who have introduced CO 2 heat pump water heaters," the company stated. 2013-09-25 · Experimental analysis of a prototype R744 water/water heat pump equipped with a two-phase ejector. • Tests performed at typical hot tap water production settings. • Additional test for heat pump assessment at space heating conditions. • Ejector useful to improve performances, especially when high throttling losses are expected.

With a CO₂ heat pump system, every 1kW of input energy consumed produces an average of 3.9 x the input as output energy or heat by extracting heat from the outside air. Summary Producing 90°C hot water with an average COP of 3.9, makes Revere™ CO₂ Heat Pumps an ideal energy efficient domestic hot water and space heating system for industrial, commercial and residential applications. The heat pump is one of a number of innovations found in Hyundai and Kia’s current generation of EVs, with heat management also used to realize major improvements in EV battery packs.

heat pump mode. The production vehicle components used had been optimized for A/C operation with R134a and were used as a proof-of-concept for the R134a/R744 blend in heat pump operation. Many improvements could be made in future research to optimize the components for both A/C and heat pump operation with R445A as the refrigerant.

Ecodan heat pump systems, which can be used for heating, cooling and domestic hot water (DHW) production, use the refrigerant R410A – in contrast, the QAHV uses the refrigerant R744.

• Comparison of cooling/heating performance of R744 and R134a systems is made. • The performance merits of CO2 is re-evaluated. • R744 heat pump system is highly recommended for electric Enerblue, chiller and heat pumps, Propane (R290) and CO2 (R744), very low-GWP, high-efficiency natural refrigerant.
