How subcooling increase the COP of vapour compression refrigeration?
The sub-cooling or under-cooling in the saturated liquid line increases the refrigeration effect or cooling effect, thus the COP of VCR system increases.
What is Vapour absorption machine?
It is a refrigeration unit based on Vapour Absorption Refrigeration Cycle (typically refrigerants used are Water or Ammonia).
Why do you need to recharge the refrigeration system?
usually the refrigerant you have pumped out of the system is contaminated (either liquid/air) contaminated refrigerant is less efficiant and will lead to a short system life. refrigerant is works kind of like the rain in a water cycle. The system starts at the compresser (the heart of the system) pushing refrigerant in to the condenser (like condensation in the clouds) condensing to a liquid and heads toward the metering device (raining) The metering devise rapidly lowers the pressure of the system into the evaporator (get the picture already?) where the refrigerant collects the heat in the refrigerated space and boils into a vapour releasing it to out side the refrigerated space. obviously there is more detail then this but thats the basic operation.
How does a cooler work?
There are two basic cycles of Airconditioning/Refrigeration 1. Vapour compression cycle, 2. Vapour Absorption Cycle Vapour compression cycle is used in most of the airconditioning applications but ofenly vapour absorption is used. evaporator, compressor, throateling valve, tank & condensor are the major parts of this cycle.
Why does exhaled air saturated with water vapour?
water vapour is produce during respiration
How subcooling increase the COP of vapour compression refrigeration?
The sub-cooling or under-cooling in the saturated liquid line increases the refrigeration effect or cooling effect, thus the COP of VCR system increases.
Why actual cop of vapour compression refrigeration is less than theoretical cop?

What has the author Brian Mongey written?
Brian Mongey has written: 'The experimental evaluation of a ternary mixture as an alternative to R22 in the vapour compression refrigeration cycle'
What is the function of absorber in vapour absorption refrigeration system?
in orde to reduce the pressure........cming from the evaporator
What is Vapour absorption machine?
It is a refrigeration unit based on Vapour Absorption Refrigeration Cycle (typically refrigerants used are Water or Ammonia).
What role does a compessor play in a refrigeration system?
In vapour compressor refrigeration system the low pressure and temperature vapour refrigerant from evaporator is compressed. where it is compressed to a high pressure and temperature. From compressor refrigerant goes to condenser where where it changes the phase. from condenser refrigerant goes to evaporator through expansion device.
Why throttle valve is used instead of expansion cylinder in vapour compression refrigeration system?
In vcrs system there is a phase conversion system i.e. liquid state to gases state and this happens with latent heat of working medium but on the other hand there is only gases expansion on expander cylinder and no phase changes occurs and in cylinder we can not expend two phase system..
What are the disadvantages of discharge lamp?
Disadvantages of sodium vapour discharge lamp
Why is the suction pipe of vapour compression refrigeration system insulated?
To minimize sweating of the air around the pipe. When the air comes in contact with a cool surface, its water vapor condenses!
How does vapour compression work?
See my answer to~How does air conditiong work~ on this site.
How water flow rate affect performance of vapour compression cycle?
the sun heat up the water
