Which of the following properties of R-410A contributes to its efficiency?

The property of R-410A that contributes to its efficiency is its high pressure capacity. High pressure capacity in a refrigerant like R-410A enables it to operate effectively in HVAC systems, allowing for greater heat transfer and efficient operation. This characteristic reduces the compressor workload, resulting in less energy consumption and improved overall system efficiency.

In HVAC applications, the ability of a refrigerant to maintain higher pressures allows for efficient heat exchange at both the evaporator and condenser coils. This leads to better cooling performance and effective climate control.

While other properties are relevant to refrigerants, they do not specifically contribute to the overall efficiency in the same way as high pressure capacity. High thermal conductivity helps with heat transfer but doesn't directly influence energy efficiency. Low specific heat can be advantageous in certain scenarios, but it does not enhance efficiency overall, similar to how low latent heat may affect moisture removal rather than energy consumption directly.
