When the refrigerant leaves the compressor, it is in a high-pressure gas state. It then flows through the condenser coils, where it releases heat and condenses into a high-pressure liquid before entering the expansion valve.
The device in a refrigeration system that causes the refrigerant to go from a liquid to a gas is the expansion valve. It controls the flow of refrigerant into the evaporator, where it absorbs heat and evaporates into a gas, cooling the surrounding space.
If liquid refrigerant enters the compressor cylinder while it's running, it can damage the compressor. Liquid refrigerant is not compressible like gas, causing hydraulic lock and putting excessive strain on the compressor motor. This can lead to mechanical failure and decreased efficiency of the refrigeration system.
In the modern refrigeration cycle, the compressor plays a crucial role by compressing the refrigerant gas, increasing its temperature and pressure. This high-pressure gas is then condensed into a liquid before entering the expansion valve. The compressor helps maintain the flow of the refrigerant throughout the system, enabling the cycle to remove heat from the space being cooled.
In a refrigerator, a refrigerant undergoes two main changes of state: from a low-pressure gas to a high-pressure gas in the compressor, and then from a high-pressure gas to a high-pressure liquid in the condenser. This process allows the refrigerant to absorb heat from the interior of the refrigerator and release it outside.
In a refrigerator, energy transfers occur through the following processes: The compressor compresses a refrigerant gas, causing it to release heat energy into the surroundings. The high-pressure gas then flows through the condenser coils, where it releases more heat energy and condenses into a liquid. The liquid refrigerant flows into the evaporator coils inside the refrigerator, absorbs heat from the interior, and evaporates back into a gas. The gas is then sucked back into the compressor to start the cycle again.

It cools the liquid refrigerant after it is compressed from gas to a liquid from the compressor.

Refrigerant is superheated when leaving the evaporator so that the compressor is not getting liquid along with the gas, becauseÊliquid can cause damage the compressor.

No , a high temperature high pressure ( gas )
Yes. The basic components of the refrigeration system are the refrigerant, compressor, condenser and receiver, expansion device and the evaporator. One cycle: Refrigerant travels to Compressor (A) to Condenser (B) to Expansion device (C) to evaporator (D). The refrigerant gas at low pressure and temperature is drawn into the compressor. The gas is compressed to a higher pressure, which causes an increase in the temperature. The refrigerant gas at a high pressure and temperature passes to the condenser (point B), where it is cooled (the refrigerant gives up its latent heat) and then condenses to a liquid. The high pressure, low temperature liquid is collected in the receiver. The high pressure liquid is routed through an expansion valve (point C), where it undergoes an abrupt reduction in pressure. That pressure reduction causes part of the liquid to immediately vaporize or flash. The vapor and remaining liquid are cooled to the saturation temperature (boiling point) of the liquid at the reduced pressure. At this point most of the refrigerant is a liquid. The boiling point of the liquid is low, due to the low pressure. When the liquid refrigerant enters the evaporator (point D), it absorbs heat from the process and boils. The refrigerant gas is now at low pressure and temperature, and enters the suction side of the compressor, completing the cycle.
Automotive refrigerant is typically charged as a gas to ensure proper and efficient distribution throughout the air conditioning system. Charging as a gas allows for better control of the amount of refrigerant being used and helps prevent liquid slugging, which can damage the compressor.
superheat gas
Evaporation is the primary principle. The three primary components of most residential air conditioners are: # Compressor # Condenser # Evaporator As the refrigerant is compressed in the compressor, lowering the temperatures required to change from liquid to gas and gas to liquid. This is an exothermic, or heat generating, process. The compressed refrigerant, still under pressure, passes through the condenser. For residential systems, this is the "fan in a box" part of the air conditioning system outside. The condenser is actually blowing heat away from the refrigerant. Because the refrigerant is pressurized, the temperature is low enough for the refrigerant to turn liquid. The evaporator is where the cooling actually happens. When the pressure is reduced, the refrigerant evaporates; it turns from liquid to gas. Evaporation is an endothermic, or heat absorbing, process. The refrigerant absorbs heat from the air around it. This leaves the air around the evaporator much cooler and ready to be blown into the house. (Most refrigerators operate using the same process.)
