How does a ammonia purger work?
An ammonia purger removes air and noncondensables from the ammonia system by directing vapor from the condenser, where air collects, through cold liquid ammonia. This condenses the ammonia and separates noncondensables which are then removed from the system.
How does the ammonia clock work?
The ammonia clock was the first atomic clock invented by the US National Bureau of Standards in 1948 that measured the speed of the vibrations of nitrogen atom in ammonia molecule.
How can remove the ammonia from methanol?
assuming it's trace ammonia in lots of methanol, you can probably just heat the methanol to boiling and that should get rid of all the ammonia. molecular sieves (size 3 angstroms) would also probably work. if it's more than a trace amount, you can go for distillation.
How does anhydrous ammonia work in refrigeration?
Liquid is sent to the evaporator (from recirculator,Supply vessel))and pushed through an expansion valve or a metered hand vavle and sprayed into a reduced pressure atmosphere( the evap coil).When pressure is reduced,tempature is reduced.Pressure on low side(suction side) 0-psi,misty saturated liquid is now -28 degrees.The now misty saturated vapor absorbs heat(heat in room brought to evaporator by means of fans drawing it in) and turns ammonia saturated liquid/ vapor into a gas.Which is then sucked back in to the compressor to get compressed to at-least 20 degress over ambient(outdoor) temp.That gets sent to a condenser (galvanized box with fans and a water pump to spray out of overhead nozzles to (rain) over pipes containing the ammonia)to condense hot vapor into liquid again.Liquid now gets sent to the receiver(holding vessel) and from there to the intercooler/sub-cooler to further cool the liquid.The colder the liquid the more heat it can pick up in the evaporator.And finally from the intercooler to the recirculator,which is used to pump out to the evaporator and to receive returning liquid from the evaporator, if there is any.
What is a deffination of energy?
Physics. the capacity to do work; the property of a system that diminishes when the system does work on any other system, by an amount equal to the work so done; potential energy. Symbol: E e= mc2

What kind of training does osha require?
Osha requires knowing how to work an aerial lift, how to unload Anhydrous Ammonia, knowing accident preventions signs and tags, knowing about bloodborne pathogens.
What is a generator in vapor absorption refrigeration system?
The generator in a vapor absorption system for a refrigerator consists of all of the components that make the refrigerator work. The system allows for compression, condensation, evaporation, and expansion.
Would bleach work as a fertilizer?
NO.NO.NO.NO.NO. definitely not! Although it will decompose rapidly to simple salts, and so would not be a particular harm to the environment, bleach contains nothing beneficial to plant growth. Ammonia, on the other hand, is very commonly used as a fertilizer in the US, with many farmers, particularly in the Midwest, applying anhydrous ammonia to their fields for the nitrogen content.
How does Back-pressure valve work in dairy production?
Back pressure regulating valve is used in ammonia refrigeration plant to maintain the minimum pressure in the evaporator coils. It helps in preventing ice formation / choke upin the PHE chiller.
Refrigeration can be described as?
Refrigeration is a process in which work is done to move heat. It was a closed-cycle that could operate continuously, as he described in his patent.
Does a central air conditioner need water to work?
no... water in the refrigeration system is a very bad thing. The air conditioning system will remove moisture (humidity) from the air and require a drain to channel that water away from the coil.
classes to learn about refrigeration?
There are specific classes you can take to learn more about refrigeration and how refrigerators work at your local community college or YMCA / YWCA center.
Who is Frederick McKinley Jones?
An American entrepreneur and inventor, notably for his work on refrigeration.
What is a commercial refrigeration repair man?
There are lots of things a commercial refrigeration repair man does. They will mainly work on expensive, high maintenance commercial fridges, as they have to have a high uptime.
How does the ammonia clock work?
The ammonia clock was the first atomic clock invented by the US National Bureau of Standards in 1948 that measured the speed of the vibrations of nitrogen atom in ammonia molecule.
What is the cofficient of performance in the refrigeration system?
Coefficient of performance, or COP, is defined differently for heating and cooling applications. For heating: COP=(heat supplied + work)/work For cooling: COP=(heat removed)/work Work in this case refers to the compressor and other motors.
