👉 A working fluid, also known as a refrigerant or heat transfer fluid, is a substance used in various thermodynamic systems, primarily for heat transfer processes. It circulates through a closed loop, absorbing heat from a cooler area and releasing it to a warmer one, thereby facilitating cooling or heating. These fluids are designed to have specific properties such as low boiling points, high latent heat of vaporization, and good thermal conductivity to efficiently transfer heat. Common examples include refrigerants like R-134a and R-410A, which are used in air conditioning systems, refrigerators, and heat pumps. The choice of working fluid depends on factors like efficiency, environmental impact, and safety considerations.
