Where does refrigerant go after it leaves the purge unit of a low-pressure Centrifugal system?

condenser


When refrigerant leaves the compressor the refrigerant is liquid or gas?

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.


What is refrigerant as it leaves an auto AC compressor?

High pressure vapor.


Is refrigerant a low pressure liquid as it leaves the condenser?

No, refrigerant is not a low-pressure liquid as it leaves the condenser. Instead, it exits the condenser as a high-pressure liquid after dissipating heat. This high-pressure liquid then flows to the expansion valve, where it is allowed to expand and drop in pressure before entering the evaporator.


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.


Where does the refrigerant go when it leaves the evaporator?

The evaporator


What is suction and discharge head?

These are terms used by refrigeration and air conditioning techs. The suction is refrigerant returning to the compressor from the evaporator, or the low side. The high side is the discharge or head pressure, where high temperature high pressure gas leaves the compressor to flow into the condenser. These systems should only be worked on by licensed and experienced techs.


If an air conditioner evaporator coils is setup so the refrigerant is vaporized at forty five degrees Fahrenheit What is the pressure in the evaporator coil?

The pressure in the evaporator coil would depend on the type of refrigerant being used. Different refrigerants have varying pressure-temperature relationships. Without knowing the specific refrigerant being used, it is not possible to provide an accurate pressure value.


What state is refrigerant in when it leaves the condenser?

In Liquid state


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.


What is the principle of air conditioning?

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.)


What is refrigerant after it leaves compressor liquid or vapor?

super heated gas.
