Front

What is the pressure within the compressor crankcase compared to?

Back

The pressure within the compressor crankcase is the same as the low side pressure.

Front

When does the discharge reed open in a compressor?

Back

The discharge reed will only open when the pressure within the cylinder is higher than the discharge pressure.

Front

Which compressor body style cannot be serviced?

Back

Hermetic.

Front

Which compressor body style has a shaft seal?

Back

Open Drive.

Front

When does the suction reed open in a compressor?

Back

The suction reed will only open when the pressure within the cylinder is lower than the suction pressure.

Front

Define a Hermetic compressor.

Back

A Hermetic compressor is a type of compressor that is sealed and cannot be serviced.

Front

What is the function of a discharge reed in a compressor?

Back

The discharge reed allows refrigerant to exit the compressor when the cylinder pressure exceeds the discharge pressure.

Front

What is the role of a suction reed in a compressor?

Back

The suction reed allows refrigerant to enter the compressor when the cylinder pressure is lower than the suction pressure.

Front

What is the main difference between an Open Drive and a Semi Hermetic compressor?

Back

An Open Drive compressor has a shaft seal, while a Semi Hermetic compressor is partially sealed and can be serviced.

Front

Explain the term 'compressor crankcase'.

Back

The compressor crankcase is the housing that contains the compressor's moving parts and is where the low side pressure is measured.
