When evaluating refrigerants for HVAC applications, it’s essential to consider thermodynamic properties such as boiling point, latent heat of vaporization, and pressure-temperature relationships. A refrigerant with a low boiling point allows for efficient heat transfer at lower temperatures, while a high latent heat of vaporization enables more heat to be transferred per unit mass of refrigerant. Stable pressure-temperature relationships ensure that the refrigerant operates within a safe and efficient range. These properties directly impact system performance, energy efficiency, and overall system design.
