How many types of HVAC certifications are there? - Answer✔There are 4 types.
What does a metering device do? - Answer✔The metering device causes a reduction in
pressure, and therefore a reduction in saturation temperature.
What is absorbed in the evaporator? - Answer✔Heat is absorbed in the evaporator.
What happens in the evaporator? - Answer✔Heat is absorbed in the evaporator and causes the
refrigerant to boil from liquid to vapor.
