A vehicle air conditioning system is required for passenger cabin thermal comfort. An electric compressor, which consists of a compressor and an electric motor, drives the electric vehicle air conditioning system. The refrigerants CFC-12, CFC-22, and HFC-134a are used in almost every air conditioning system.
An electric vehicle stores ready-to-use electrical energy in a battery. Modules are made up of a number of cells that make up a battery pack. The vehicle is ready to use when the battery has enough energy stored. In recent years, battery technology has advanced significantly.
However, the ozone layer will be harmed by CFC-12 and CFC-22. The significant Earth’s greenhouse effect is exemplified by the GWP values of CFC-12, CFC-22, and HFC-134a, which have extremely high global warming potentials. Using a mixture of HC-134 to replace HFC-134a, new experimental measurements and analysis are presented in this article.
The coefficient of performance, energy factor, and cooling capacity for both HFC-134a and HC-134 rise as a result of the refrigerating effect. HC-134 has a nearly twice as strong cooling effect as HFC-134a. Additionally, HC-134 has a coefficient of performance value that is 36.42% higher than that of HFC-134a. Then, HC-134’s energy factor value is 3.78 percent higher than that of HFC-134a.
The Global EV refrigerant 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.
To manufacture its low-GWP refrigerant R474A for air conditioning systems in electric vehicles, Daikin will make an investment of more than $75 million in a new plant in Japan.
Production at the plant in Yodogawa Seisakusho, Settsu City, Osaka Prefecture, will begin in 2027, according to Japanese reports. The company will spend billions of yen in 2024 to run a test plant before going into mass production.
The refrigerant, which was first announced in 2021, is made to make electric vehicles’ cooling and heating systems use less energy and increase their range.
The capacity of a R1234yf vehicle heat pump system is said to decrease by up to 40% when the ambient temperature drops from 0°C to -10°C, according to research. Automobile manufacturers acknowledge this as a significant issue in colder climates.
