This course will concentrate on the refrigeration cycle and it’s components along with the different methods of charging different systems.

Step by step animated tutorials and hands-on operation of the components of the refrigeration cycle.

The student will experience a highly interactive course while:

• Learning about condensing pressure at which the refrigerant changes state from a vapor to a liquid.
• Learning about evaporating pressure at which the refrigerant changes state from a liquid to a vapor.

While modern refrigerants exist either in the vapor or liquid state (rarely in the frozen or solid state), refrigerants can co-exist as vapor and liquid. Along with refrigerant pressures and states, the student will:

• Learn what and when a refrigerant is saturated.
• Learn what and when a refrigerant is superheated.
• Learn what and when a refrigerant is sub-cooled

After a thorough knowledge of the pressures, states, and conditions of the refrigerants and how they exist in the refrigeration cycle, the student will use different charging methods such as:

• Capillary tube
• Piston
• TXV
• Critical charge
• Sight glass
