WebMar 1, 2024 · The hot vapor from the compressor enters the condenser, and the superheat (temperature above condensing temperature) is then removed. The refrigerant then begins to change state from vapor to liquid (condensing). The refrigerant maintains a constant temperature until every molecule of vapor is condensed.
First of all, we all know that most elements can exist as a liquid, gas or solid. Of these three states, only a gas (also sometimes called vapor or steam) can be superheated.1 Superheating occurs when a gas is heated above the boiling point of that element in its liquid form.2 For example, water boils at 212 degrees … See more Saturation is a term to describe the point where a substance changes state, such as from liquid to gas or solid to liquid. In our example of boiling water, saturation would be the boiling point of 212 degrees F. When the substance … See more Superheat is calculated as the difference between the saturation temperature of a substance and the actual temperature of the gas.3 When it … See more Superheat is an important measurement for HVAC technicians to understand.

WebEach is a part of the refrigeration cycle which will be explained in more detail below. Fluid Circulation. Industrial water chillers use fluid circulation to deliver the heat from the process to the chiller. This fluid is typically water or a water/glycol mixture. ... Superheat is when all the liquid refrigerant has evaporated, and the gas ... WebMay 9, 2009 · When vapor changes to liquid, some heat is removed at the saturated condensation temperature. Further reduction in temperature is subcooling. When liquid changes to vapor, extra heat is introduced in liquid. Upon reaching the boiling point of the refrigerant, a further increase in temperature is superheat. To understand large industrial …
