- Q1. What is the superheat , how to calculate superheat
- Ans.
Superheat is the temperature increase of a vapor above its boiling point at a given pressure.
Superheat is important in HVAC systems to ensure proper refrigerant flow and system efficiency.
It is calculated by subtracting the boiling point temperature of the refrigerant at a given pressure from the actual temperature of the refrigerant.
The ideal superheat value varies depending on the type of refrigerant and the specific...
- Q2. What is sup cooling What is function of expension value
- Ans.
Subcooling is the process of cooling a liquid refrigerant below its saturation temperature.
Subcooling is achieved by removing heat from the refrigerant after it has been condensed.
It ensures that the refrigerant is in a liquid state before it enters the expansion valve.
The expansion valve reduces the pressure of the refrigerant and controls the flow rate into the evaporator.
This causes the refrigerant to evaporate and ...
- Q3. Why are increased head pressure
- Ans.
Increased head pressure in HVAC systems can be caused by various factors.
Dirty condenser coils
Blocked or restricted airflow
Refrigerant overcharge
Malfunctioning expansion valve
Faulty compressor
Ambient temperature increase
Clogged filter drier
Low refrigerant charge
Kinked or blocked refrigerant lines
