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

R744 heat pump

A heat pump works the same as an inverted refrigerator. Just like a refrigerator, a heat pump uses electricity and does so very efficiently. 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. A water-cooling system for Hyundai and Kia’s EV battery packs, rather than conventional air cooling, have yielded further increases in range without increasing physical dimensions.

R744 heat pump with vehicle cabin and HVAC equipment. supplemented with standards equipment like an evaporator, a gas cooler and a receiver. Fig. 2 shows the system configu-ration. Heat pump model was connected with a vehicle cabin and other HVAC equipment. We added a fan, an air valve, a duct and 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. After all, pure hot water heat pumps, which are tasked with generating particularly high hot water temperatures, have to meet very different requirements of their own.
