R744 (Carbon dioxyde) R744, or carbon dioxide, is making its re-entry into the industrial refrigeration scene. Once thought to be a wasteful chemical requiring too much high pressure to be feasible as a coolant, environmentalists now hail R744 as an answer to growing concerns.

Det har även utmärkta termodynamiska egenskaper och låg energianvändning gör den lämplig för en rad olika tillämpningar såsom industriell värmeåtervinning, kyld lagring, fraktfartyg, kommersiell kylning och mobil luftkonditionering. Provides information on CO2 technology for heating, cooling and refrigeration. Includes news, products, jobs, events, knowledge, forum, blog and a worldwide directory of partner companies.

In the second part of this report, a theoretical comparison of R744 and R410A is made. The theoretical cycle performance of R410A and R744 is compared on the basis of the comfort of the conditioned space, which is determined by dehumidification in cooling mode and the supply air temperature in heating mode. Cycles are ISA has a unique range of cabinets with natural refrigerants R290 and R744, in line with EU regulation 517/2014 which abolishes the R404a gas. Valeo has developed an environmentally friendly air conditioning system using the R-744 refrigerant (made up of natural CO 2), thus eliminating the direct impact of air-conditioning systems on global warming.. This system made its World Premiere in June 2017.
