The function of the evaporator in a refrigerant system is to_____ heat.
Absorb.
After the air has pass through the evaporated is the air hot or cold.
Cold
The hot gas discharge line in a refrigeration system connects the:
Compressor to the condenser
What material are use to make the suction and liquid line.
Copper tubing.
Name seven component or a basic refrigerant cycle in order for refrigeration flow. Begin at any point in the cycle.
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.
The ____is the second division point between the high and low pressure side of a refrigerant system, the compressor being the first division point.
Refrigerant control.
The basic refrigeration system consist of____. Components
Seven (7)
Refrigerant in the ____ is best described as a low-temperature, low pressure, superheated gas.
Suction line..
What is the condition of the refrigerant in the suction line.
Super heated gas , low temperature low pressure.
By controlling the boiling point (pressure)in the evaporator you all so control the
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.
