What is flooding point?
In a packed or tray column where you have vapor flowing up and liquid flowing down, there is an upper limit to how fast the liquid can drain downwards. The point at which liquid cannot flow down as fast as it is coming into the column is the "flooding point". The actual flooding point is partly dependent on how fast the liquid can flow down with no vapor flowing upwards and the rate at which vapor is trying to flow upwards. Cross sections of the column occupied by vapor are not available for liquid flow - effectively reducing the cross-section for downward flow of the liquid. You also get entrainment of liquid in the upward flowing vapor and drag on the liquid as it fights the direction of the vapor flow - the vapor wants to go up while the liquid wants to go down. This additional drag also slows down the flow of liquid trying to drain downward in the column. There is an analogous condition for two-phase liquid/liquid extraction columns.
Does civilian personal protective equipment protect individuals from liquid or vapor hazards?
Yes, civilian PPE can protect individuals from liquid or vapor hazards, or from both, if it is selected correctly and maintained and worn properly.
What is BLEVE?
BLEVE is an acronym for Boiling Liquid Evaporating Vapor Explosion. Usually this is regarding LPG or Liquid Propane Gas.
Why do chillers using CFC-11 and HCFC-123 require purge units?
These refrigerants have higher boiling points than say R12 or R22. Thus when a machine using them operates the low side will run in a vacuum. So any low side leak points will suck in air rather than leak refrigerant out. A purge unit constantly samples the condenser gas and removes the air and water vapor which has been pulled in at these leaking points and periodically releases them to atmosphere while it condenses any refrigerant vapor picked up in the sample mix to a liquid and returns it to the machine.
What is the Definition for simple distillation?
The two most elementary forms of distillation are a continuous http://www.answers.com/topic/equilibrium-flash-vaporization and a simple http://www.answers.com/topic/batch-distillation. In a continuous equilibrium distillation, a continuously flowing liquid feed is heated or reduced in pressure (flashed) so as to cause partial vaporization. The vapor and liquid disengage while flowing through an open drum, and the products emerge as vapor and liquid streams. The vapor product can be condensed to form a liquid distillate. It is also possible to use a vapor feed, subjected to cooling and thereby http://www.answers.com/topic/partial-condensation, again followed by http://www.answers.com/topic/disengagement of the resultant vapor and liquid in an open drum. In a simple batch distillation, an entire batch of liquid is initially charged to a vessel and is then heated, typically by http://www.answers.com/topic/condensation of steam inside a metal http://www.answers.com/topic/coil within the vessel. Vapor is thereby continuously generated, and may be condensed to form a liquid distillate, which is collected. In the batch distillation, increments of vapor are formed in equilibrium with all liquid compositions ranging from the original to the final, whereas the continuous equilibrium distillation gives vapor in equilibrium with only the final liquid composition. Since the distillate consists primarily of the more volatile components and the feed liquid contains more of these substances than does the final liquid, the simple batch distillation gives a more http://www.answers.com/topic/enrichment distillate than does the continuous equilibrium distillation.
Does the refrigerant in the evaporator become liquid to vapor or stays vapor?
it starts as a liquid and turns into vapor before going into the compressor
What is refrigerant as it leaves an auto AC compressor?
High pressure vapor.
Is refrigerant leaving a compressor in a cars air conditioning system high pressure vapor high pressure liquid or low pressure vapor?
high pressure vapor
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 a direct expansion evaporator?
Refrigerant enters a direct expansion evaporator as a saturated liquid vapor mix and leaves as a superheated vapor.
How the compressor working?
Refrigerant enters the compressor inlet as a low pressure vapor. The compressor increases the pressure, and discharges it as a high pressure vapor.
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.
Refrigerant enters a compressor as a low pressure vapor?
Yea
What state is refrigerant entering the compressor?
Low pressure vapor
What does AC compressor do?
Cycles refrigerant through the system and changes the state of the refrigerant from a low pressure vapor to a high pressure vapor.
Why does refrigerant pressure decrease in a refrigerant cylinder while charging with vapor?
When vapor refrigerant is pulled out of a cylinder the vapor is reduced and the liquid boils to replace the vapor that has left the cylinder.
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.
