Which refrigerants are high pressure?
230-250
An instrument used to measure the pressure of gases in closed containers is a?
Manometer
How is temperature affected if there is a high pressure in the atmosphere?
High pressure = High temperature
Comparison between normal temperature pressure and standard temperature pressure?
there is no difference
Can changing the pressure of a gas have on its temperature?
yes decreasing the pressure of a gas can decrease its temperature
What is discharge pressure of Rerigerant134a?
It depends on the ambient condensing temperature. A pressure temperature comparison chart for 134Aa can be found at http://www.csgnetwork.com/r134apresstempconv.html Different refrigerants condensence and evaporate at different temps/pressure
Why do people need to keep containers with gasses under cool condition?
Because gasses expand when the temperature rises, which puts extra pressure on the containers which again may cause them to explode if the temperature rises too much. When stored cold, the level of pressure will stay well within the limits that the containers safely can withstand.
Which refrigerants are high pressure?
230-250
What should be high side pressure in ac?
You need to specify what kind of system. Automotive AC systems and home AC systems use different refrigerants. That, along with the temperature/pressure relationship and ambient air temperature, all factor into what your high pressure (and, consequentially, low pressure) side should read on your manifold pressure gauge.
What is the refrigerants state when entering the metering device?
High pressure liquid
Define a pure compound refrigerant and give two examples?
a refrigerant that does not change its pressure/temperature relationship when changing phases. CFC are pure compound refrigerants.
What is the difference in a domestic refrigerator's high side pressure and a air condition's high side pressure?
The difference would be due to the different refrigerants used by each which is not given. Also the refrigerator will have a more constant condenser pressure because it is within an environment where the ambient temperature varies little.END
Are tire pressure sensors reusable?
yes ofcorse x x x
Do liquids exert pressure on the walls of the containers?
Yes
Should refrigerants be operated at temperatures above or below their critical temperature?
The critical temperature of a refrigerant is the point at which it changes states. In a refrigeration scenario, this happens 2 times per cycle. The refrigerant is a liquid on the high pressure side, and below its critical temp. On the low pressure side it becomes a vapor (gas) and its above its crictal temp. So the answer is both, depending on what side of the system you are on.
How does pressure affect temperature?
as pressure increases, temperature increases
What has the author Jun-Young Choi written?
Jun-Young Choi has written: 'A generalized pressure drop correlation for evaporation and condensation of alternative refrigerants in smooth and micro-fin tubes' -- subject(s): Refrigerants, Thermomechanical properties
