Refrigerant Flashcard 10

Front

What is the factory charge in a split system using R-22 if it shows 6 lb 8 oz in the outdoor condensing unit and 2 oz in the evaporator, with refrigerant lines of 30' long?

Back

7 lb 11 oz.

Front

What happens if a critically charged refrigeration system is overcharged?

Back

Increased operating pressures.

Front

What does charging a refrigeration system refer to?

Back

Adding refrigerant to a system.

Front

Can refrigerant be added to both the high and low pressure sides of the system when the system pressures are lower than the pressure in the refrigerant tank?

Back

True.

Front

In what form is refrigerant normally put into the system through the suction line?

Back

Vapor form.

Front

What is the purpose of the liquid line in a refrigeration system?

Back

To transport liquid refrigerant from the condenser to the evaporator.

Front

What is the role of the suction line in a refrigeration system?

Back

To carry vapor refrigerant from the evaporator to the compressor.

Front

What is the effect of overcharging a refrigeration system on cooling capacity?

Back

It does not increase cooling capacity; it can lead to inefficiencies.

Front

What is the significance of the refrigerant charge in a refrigeration system?

Back

It ensures optimal performance and efficiency of the system.

Front

What is the typical refrigerant used in older air conditioning systems?

Back

R-22.
