Gas, or refrigerant, is a substance that absorbs heat and transfers it to another substance. It's used in a variety of appliances, including refrigerators. There are many different types of gases used in refrigeration systems today, but the most commonly used are R-134a and R-438A.
Refrigerants have low evaporation points so they don't evaporate easily into the air when they're used in a refrigerator or air conditioner.
This helps keep your food cool without wasting too much energy on cooling gases that could be better spent keeping your food at a safe temperature.
R22--Older refrigerators used to use this gas, but it was being phased out since it was ozone-depleting. This gas is no longer used in modern refrigerators.
R134A--This gas is well-liked these days since it protects the ozone layer. While R134a is a widely used refrigerant with excellent cooling properties, it is also a greenhouse gas, and efforts are underway to develop alternative refrigerants with lower global warming potential. As such, some manufacturers may choose to phase out the use of R134a in the future in favor of these alternatives.
R438A--Manufacturers employ this gas as an alternative to R22 gas due to its non-ozone-depleting properties. This gas can be found in many freezers that formerly used R22 gas.
R600A--Due to its non-ozone depletion and low global warming feature, it is a halogen-free refrigerant that is extremely common these days. It is both energy-efficient and combustible.
HFC-134a--In today's refrigerators, this refrigerant gas is widely employed and a popular choice. It has been effectively condensed. As a result, it may readily cool down the machine's surroundings without causing ozone depletion.
TCL refrigerators are a new and innovative addition to the market. The TCL P470CD model comes equipped with a Multi-Air-Flow system that helps to keep food fresh for longer while preserving its original flavor, shape, and color and Automatic Anion-releasing Technology (AAT), offering bacteriostatic, purifying, and antioxidation benefits in a compact design. With a large capacity of 470 liters, the refrigerator has a smart inverter compressor that saves energy and reduces noise. The fridge also comes with an LED touch panel which allows for temperature adjustments in both the fridge and freezer, independently!
How a refrigerator operates in detail
The process of cooling down your food in a refrigerator is very simple. The refrigerant gas is used to cool the fridge and also in air-conditioning units. The working process of a refrigerator is as follows:
