Calculating Superheat
What is Superheat?
Superheat is the amount of heat required to raise the temperature of a substance above its saturation point.
In other words, it’s the amount of heat required to change the state of a substance from a liquid to a vapor.
For example, water has a saturation point of 100 degrees Celsius.
This means that in order to change the state of water from a liquid to a vapor, you would need to add enough heat to raise the temperature of the water above 100 degrees Celsius.
The amount of heat required to do this is called the superheat.
What is the formula for finding superheat?
The total superheat calculation is as follows:
Degrees compressor in temperature - saturation temperature = total superheat
How to Measure Superheat
Measuring superheat is relatively simple.
First, you’ll need to determine the saturation temperature of the substance you’re working with.
For water, this is 100 degrees Celsius.
Once you know the saturation temperature, you can measure the temperature of the substance using a thermometer.
The difference between the measured temperature and the saturation temperature is the superheat.
For example, if you measure the temperature of water and it is 120 degrees Celsius, then the superheat would be 20 degrees (120-100=20).
Summary
Superheat is an important concept in HVAC applications.
By understanding how to measure and calculate superheat, you can optimize the performance of your HVAC system, save energy, and troubleshoot potential problems.
Now that you know how to calculate superheat, put your knowledge into practice!
