What is the purpose of an evaporator?
An evaporator in a refrigeration system works by passing warm air over it's coils. The warmth of the air heats the liquid refrigerant inside, causing it to boil into gas. At the same time, the air looses it's heat and turns cold. It is heated by the surrounding and is passed through again and again until the surrounding is the same temperature as the liquid refrigerant. Then, the system shuts off, or cycles back, depending on the metering device.
Why is absorbance not measured directly?
Simply because we cannot measure light absorbed. We are, however, able to measure light transmitted through the use of a spectrophotometer. The device works by shining light of a specific wavelength on a substance and measuring the amount of light that gets through. This "transmittance" has a negative logarithmic relationship to absorbance.
How do you measure specific gravity in home brew?
There are several methods but will need some type of special equipment to measure this. You can do it with a device which you float in a sample of your beer. There is another device which does it by measuring light transmission through a sample of your beer.
In the maesurement 43.52 cm which digit is the most uncertain?
43.52 centimeters (cm) has four significant figures. The final figure in place four of '2' is the most uncertain. This is because the measurement device or calculation may have originally been 43.516 through 43.519 before rounding or due to instrumentation uncertainty.

Where does flash gas get created?
As the refrigerant exits the metering device
What type of refrigerant metering device is used on most refrigerators?
A curator
What is the causes of low super heat?
Not enough refrigerant, restriction on the metering device.
What is the refrigerant entering the metering or expansion device of a refrigeration system?
superheated vapor
Function of expansion valve?
Metering device The metering device controls the flow of liquid refrigerant through the system. The liquid enters at a high-pressure, high-temperature, sub-cooled state and leaves as a low-pressure, low temperature, expanded liquid state. Accurator Piston and Thermostatic Expansion Valves are the most widely used metering devices. Accurator Pistons are widely used because of their low cost and flexibility. The piston can easily be changed to match the capacity of the condensing unit. The Thermostatic Expansion Valve (TXV) is the most efficient type of metering device. The TXV automatically adjusts the flow of the liquid refrigerant based on the superheat of the refrigerant leaving the evaporator coil. As the load on the evaporator increases, the TXV increases the flow of refrigerant. This maintains the proper superheat. The TXV is efficient throughout a variety of system operating conditions, while the accurator is efficient only under designed conditions.
How do you know where the high end or low end of your cars ac unit is?
The high pressure (discharge) side starts at the compressor outlet and ends at the metering device inlet. This side will have the smaller refrigerant lines. The low pressure (vacuum) side begins at the metering device outlet and ends at the compressor inlet. This side will have the larger refrigerant lines.
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 is a TXV valve?
Thermal Expansion Valve is a type of metering device which is one of the separation points between the high and low pressure sides of an air conditioning system (the other being the compressor). It depressurises the liquid refrigerant which passes through it, ensuring that low pressure liquid refrigerant is passed on to the evaporator.
Explain the capillary tube type refrigerant control?
capillary tube are classified under fixed oriffes metering device it is thin and long inorder to control the refrigerant pressure and temperature not to evaporate ontheir way unitl it reach the evaporator.
What is a metering device on a refrigerator?
A metering device on a refrigerator is usually a capillary(cap)tube. It is a very small copper line located somewhere between the condenser coils (outside-hot) and the evaporator coils (cooling coils). It reduces the pressure of the refrigerant coming from outside as it enters the evap coils inside. Refrigerant cools under low pressure thus cooling desired inside area when air is blown across the cold coils. Think of a kinked garden hose and how on the spicket side of the hose the pressure is great, but on the other side the pressure is decreased. That is basically the purpose of a metering device.
Where is the low press side on condensor on 95 yukon?
The condenser does not have a low pressure side, because the condenser is not on the low pressure side of the system - it is on the high pressure side, and refrigerant going into the system is at high pressure throughout the whole of the condenser. The high pressure side of an AC system begins at the compressor outlet and ends at the metering device inlet (refrigerant leaves the compressor outlet and goes directly into the condenser inlet). The low pressure side runs from the metering device outlet to the compressor inlet.
