Evaporator. Suction line. Compressor. Hot gas discharge. Condenser. Liquid line. Refrigerant control.

Name three types of air cooled condenser.

Finned tub. (force convection). Wire static (natural convection). Wall static (natural convection).

What is the conditions of the refrigerant in the hot gas discharge line.

High temperature, high pressure highly super heated gas.

In what conditions is the refrigerant as it enters the condenser.

High-temperature, high pressure, highly super heated gas.

After the air pass through the condenser is the air hot or cold.

Hot

Name two division point between the high pressure and the low pressure of the refrigeration system.

Is located at the valve plate between the suction and the discharge valve reed.

What is the purpose of the evaporator.

It absorbs heat from where it unwanted. Room ares, refrigerators.

Briefly describe the function of the compressor.

It converts a low temperature, low pressure gas to a high temperature, high gas by means of compression

Discrive the function of the component call the refrigerant control.

It meters the correct amount of liquid refrigerant into the evaporator.

What are the conditions of the refrigerant when it is in the evaporator.

Low temperature, low pressure and saturated.

In what conditions is the refrigerant as it leaves the condenser.

Medium temperature, high pressure liquid.

Which of the following is not a type of reciprocating process.

Osmotic.

Temperature.

What is the purpose of the condense.

To dispose of the heat absorbed by the refrigerant as it passed through the evaporator.

True or false the suction line is larger in diameter then the discharge line.

True.
