Does refrigerant enter the compressor as a low temperature low 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.
What is a brief description of the basic refrigeration cycle?
Starting at the compressor;Low pressure vapor refrigerant is compressed and discharged out of the compressor.The refrigerant at this point is a high temperature, high pressure, superheated vapor.The high pressure refrigerant flows to the condenser by way of the "Discharge Line".The condenser changes the high pressure refrigerant from a high temperature vapor to a low temperature liquid and leaves through the "Liquid Line".The high pressure refrigerant then flows through a filter dryer to the Thermal Expansion valve or TXV.The TXV meters the correct amount of liquid refrigerant into the evaporator.As the TXV meters the refrigerant, the high pressure liquid changes to a low pressure, low temperature, saturated vapor.This saturated vapor enters the evaporator and is changed to a low pressure dry vapor.The low pressure dry vapor is then returned to the compressor in the "Suction line".The cycle then starts over.
What is the component of a refrigeration system which changes a high pressure vapor to a high pressure liquid?
A brief discussion of the operating vapor-compression cycle is helpful to indicate other potential refrigeration problems in real systems. In the basic cycle, slightly subcooled refrigerant leaves the condenser at high pressure and flows into the liquid receiver if one is present. The refrigerant then enters the throttling device (capillary tube, TXV, etc.) where the pressure is dropped. It then enters the evaporator as a two-phase mixture (liquid and vapor) and evaporates or boils at low temperature, adsorbing heat. Slightly superheated refrigerant vapor exits the evaporator and enters the suction line accumulator, if one is present (used to trap any transient liquid slugs). The refrigerant vapor then enters the compressor where the pressure and temperature are increased as the compressor compresses the refrigerant vapor. The vapor leaving the compressor is superheated, and the compressor discharge is the hottest point in the cycle. This refrigerant is cooled and condensed in the condenser where heat is rejected, and the refrigerant is condensed to liquid. Refrigerant actually leaves the condenser slightly subcooled (subcooled liquid) to assure condensation has been complete. Any non-condensable vapors in the system will be unable to condense in the condenser and will appear as gas bubbles in the condensed liquid stream. These non-condensables may collect in the condenser and displace refrigerant from the condenser heat exchanger, thereby reducing the effective surface area of the condenser.The compressor changes the low pressure vapor to high pressure vapor sending it threw the condenser to cool and turn it back into liquid.
Is refrigerant leaving a compressor in a cars air conditioning system high pressure vapor high pressure liquid or low pressure vapor?
high pressure vapor
How do you correct when a compressor has lock up due to liquid charging?
Bleed off some of the refrigerant to get the system pressure down, then wait a while until any liquid refrigerant in the compressor has time to leak into the refrigerant loop. It may take a few minutes; since the compressor valves seal imperfectly, pressures will eventually equalize and it should be possible to start up the compressor again.
How do air conditioner work?
Air conditioning works on basic thermodynamics, hot goes to cold. 5 main parts to an AC system: Condenser (usually in front of the radiator), Metering Device (creates pressure drop in the system), Evaporator (located in your cars console which picks up heat), compressor and refrigerant(chemical liquid which boils at low temperatures). So you turn your AC on and liquid refrigerant flows through the metering device changing it to a low temperature low pressure liquid vapor(mostly liquid). As the refrigerant flows through the evaporator the "hot" air of the car is absorbed into the refrigerant which causes it to boil off into a vapor form. This low pressure vapor refrigerant then flows through the compressor turning to a high temperature high pressure vapor. That vapor then goes through your condenser, and releases heat to the outside air(vapor is hotter than outside air)and turns back to liquid refrigerant. At this point the liquid refrigerant flows back through the metering device and the cycle continues until your thermostat is satisfied, disengaging your compressor. In short you are taking that hot air in the car and transferring it outside.
What does a car condensor do?
It cools the liquid refrigerant after it is compressed from gas to a liquid from the compressor.
What does the condenser do in a refrigeration or air conditioning system?
It passes heat out of the high pressure high temp vaporized refrigerant so the it becomes a high pressure lower temperature liquid.It passes heat out of the high pressure high temp vaporized refrigerant so the it becomes a high pressure lower temperature liquid.
What is liquid slugging of the compressor?
Large quantities of liquid refrigerant enter the compressor and then mix with the lubricating oil in the compressors sump.
What is the purpose of a crankcase heater on a compressor?
to prevent liquid refrigerant from staying in the compressor after shut down
What is the device in a refrigeration system that causes the refrigerant to go from a liquid to a gas is the?
orifice
What is used compressor?
compressor is used for compress the gas or liquid to a certain level "Based on design" like In a air-conditioning compressor is used for compress the gas on high temperature and high pressure in the result gas convert to high temperature liquid form.
