What makes R-410A a preferred choice over R-22 refrigerant?

R-410A is preferred over R-22 refrigerant primarily due to its greater efficiency and lower Total Equivalent Warming Impact (TEWI). R-410A operates at a higher pressure and has a better heat transfer efficiency compared to R-22, which allows systems using this refrigerant to require less energy to provide the same cooling output. This improved efficiency not only translates to lower energy bills for consumers but also supports more environmentally friendly practices by reducing the overall energy consumption associated with the cooling process.

Moreover, TEWI is a metric that encompasses both the direct and indirect effects of a refrigerant on climate change. R-410A has a lower TEWI than R-22 because it has a lower potential for ozone depletion and possesses a higher energy efficiency, contributing to a lesser environmental impact when used in HVAC systems. Overall, these characteristics make R-410A a superior choice for modern air conditioning and refrigeration applications, aligning with current environmental standards and regulations.
