R134a Xpert Refrigerant Gas 300g N.W
R134a season refrigerant gas, also known as “Tetrafluoroethane,” belongs to the HFC category and does not contain chlorine atoms, making it ozone-friendly. Compared to R12, it offers better thermal conductivity, higher latent heat, and superior heat transfer capacity. Environmentally, it is widely accepted, and R134A has been selected as a suitable replacement for R12. This product is heavier than air, and if it accumulates to 15% of air volume in a confined space, it can accelerate heartbeat, cause dizziness, nausea, and even fainting. Therefore, it is essential to ensure proper ventilation in workshops or workspaces.
What is a Refrigerant Gas?
A refrigerant exists in either gas or liquid form and lowers the temperature in specific environments, such as refrigerators, freezers, or homes. These substances are often called “coolants” or simply “refrigerants.” They play a vital role in the cooling cycle by absorbing heat from the environment and releasing it outside. Refrigerants operate based on a thermodynamic principle known as “phase transition,” which allows the conversion of liquid to gas and gas back to liquid. This unique characteristic makes refrigerants essential in various cooling devices, including air conditioners, freezers, coolers, and refrigerators.
The Phase Transition Principle
The “phase transition” principle explains how materials change state through heat transfer. For instance, a liquid refrigerant absorbs heat from the environment to become gas, while gas can release heat and convert back into liquid. This feature enhances the effectiveness of refrigerants in cooling applications.
Types of Refrigerant Gas
You can categorize refrigerant gases based on their chemical structure into four main types:
- CFCs – Chlorofluorocarbons
- HCFCs – Hydrochlorofluorocarbons
- HFCs – Hydrofluorocarbons
- Natural Gases
Natural refrigerants include substances like hydrocarbons and carbon dioxide. In contrast, synthetic refrigerants encompass gases such as chlorofluorocarbons, hydrochlorofluorocarbons, and hydrofluorocarbons.
