Temperature Glide Explained
\n
As HVAC professionals, understanding the nuances of refrigeration and air conditioning systems is vital for ensuring efficiency and performance. One of the critical concepts in this domain is temperature glide.
\n
What is Temperature Glide? Temperature glide is defined as the temperature difference between the bubble point and dew point temperatures of a refrigerant. It is an essential factor in the performance of refrigerants, especially when dealing with blends.
\n
The bubble point is the temperature at which a refrigerant begins to evaporate (turn into vapor), while the dew point is the temperature at which the vapor starts to condense back into liquid. The gap between these two points indicates how much temperature change occurs during the phase transition in a refrigerant blend.
