In the following, hydrochlorofluorocarbon (HCFC) refrigerants were used in place of CFCs, but they were also included in the phaseout of chlorine refrigerants as ozone depleting agents.
For a refrigeration or air-conditioning system to operate properly, a decent refrigerant also referred to as working fluid must be chosen.
The refrigerant should be non-toxic, non-inflammable, non-corrosive, and environmentally benign in addition to having a suitably high vaporisation enthalpy and a reasonable vapour pressure change over the temperature range. Today’s main selection criteria include the last requirement.
Hydrofluorocarbons (HFCs) are greenhouse gases (GHGs) that are frequently employed by federal agencies in a number of products, including aerosols, air conditioning (AC), building insulation, and refrigeration.
HFCs have a high global warming potential (GWP), which raises questions about their effects as they are used more frequently to replace ozone-depleting substances (ODS) and as economic expansion increases demand for new machinery, particularly in the refrigeration and air conditioning industries. Information on current domestic initiatives and available methods to address HFCs.
The Global EV Hydrofluorocarbon refrigerants Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
In conventional cooling systems, chlorofluorocarbon and hydrochlorofluorocarbon refrigerants are frequently used. These refrigerants hasten the loss of the Earth’s ozone layer.
Adsorption air-conditioning technology has therefore received a lot of interest recently as a substitute because of its benefit of being environmentally friendly. This system can aid in lowering the amount of energy needed and thermal pollution since it is fueled by waste and/or solar heat.
There have been numerous adsorption pair studies. Automobile adsorption cooling systems frequently use the working adsorption pair of zeolite and water. Due to its relatively high operating temperature, this pair has been propelled by engine exhaust gases.
Additionally, silica gel and water are frequently used in the adsorption cooling systems of automobiles. Its comparatively low working temperature has required it to be heated by waste heat from the engine’s water cooling system.
Results indicate that using this technique can help minimise thermal emissions from engines while also improving overall engine efficiency. Adsorption cooling systems still require a number of adjustments.
