In dray expansion evaporator, the liquid refrigerant is generally fed by an expansion valve. the expansion valve controls the rate of flow of refrigerant to the evaporator. In the evaporator the liquid refrigerant is vaporized and superheated by the time it reaches to the end of evaporator. At inlet of the evaporator, the refrigerant is predominantly in the liquid form with a small amount of vapor formed as a result of flashing at the expansion valve. the liquid refrigerant passes through the evaporator, more and more refrigerant is vaporized by the load. according to the load, the liquid will come into evaporator and vaporize and reaches to superheat at the end of the evaporator. The inside of the evaporator is far from dry but wetted with liquid so named as dry expansion evaporator.

What is the difference between dry film lubricant and solid film lubricant?
Depending on the context, they usually are referring to the same thing. In some cases, people refer to air dry solid film lubricants as dry film lubricants. For more information check link.
Prevention of dry corrosion?
Anodizing method can be prevented.
What is dry-liners?
In a dry liner the coolant runs in channels in the block, and the liner is only like a sleeve stuck in a metal hole. Poorer cooling, but an easier build.
What is the tensile strength of dry paper?
Tensile strength is the resilience a towel will have against being ripped. To find out the tensile strength either a machine direction or a cross direction is used. Paper is always stronger when it is pulled in the machine direction. The dry machine direction of a towel is strong will average about 32 oz./sq. in.
What does CDB stand for in air conditioning?
CDB is used in HVAC in terms of air conditioning. The temperature of air is measured by a standard thermometer with a dry sensing bulb to determine CDB.
What is the difference between the dry or direct expansion type of evaporator to the Flooded type evaporator?
Evaporator is said to be flooded type if liquid refrigerant covers the entire heat transfer surface. This type of evaporator uses a float type of expansion valve. An evaporator is called dry type when a portion of the evaporator is used for superheating the refrigerant vapour after its evaporation.
What do flooded evaporators use what type of expansion device?
dry-type
What type of expansion device do flooded evaporators use?
dry-type
What is the expansion of dry conditions into moist areas next to deserts called?
Desertification
What happens to dry ice if it is set out at 45 degrees celsius?
It will explode due to a large Expansion of the particles
What is the dry mode on my air conditioner do?
Dry Mode is a function that will reduce the humidity in the room. In this mode, as the air passes through the air conditioner the humidity will condense on the evaporator so that the air comes out drier. Reducing the humidity makes you feel cooler and more comfortable. Dry mode uses less power than cool mode.
How do you dry N O-dimethylhydroxylamine hydrochloride?
The hydrochloride salts are very easy to absorb moisture, and they are generally sealed with parafilm. If large amount, you can dry the chemical N,O-dimethylhydroxylamine hydrochloridewith rotary evaporator, equipped with an oil pump. The chemical will will dry faster and evenly. If small amount, just use an oil pump at at room temperature.
Why do you think the sublimation of dry ice and expansion of gases are not chemical reactions?
Because they are changes of state - physical changes - VERY easily reversed.
What are the names of the inventions made during the westward expansion?
railroads barbed wire dry farming steel plow windmills sod house
Can you keep a R-22 evaporator unit and replace the R-22 condenser unit to a R410a unit by changing the TXV and flushing out the lines with dry nitrogen?
Highly not recommended. If you found a contractor who would actually do this, run don`t walk away from that guy.
Why would You have water dripping out of out central air unit?
This is water that has condensed out of the room air on the evaporator coils of the air conditioner, and it is completely normal. If the humidity is high, one will see more water condensing and dripping from the air conditioner than when the room air is dry.
Why is the sublimation of dry ice and the expansion of gases not chemical reations?
A chemical reaction is one that changes the chemical properties of a substance. Sublimation is just going from solid to a gas and is only a change of state.
