Why COP is used for evaluation of compression refrigeration system but not absorption refrigeration system?
cause its a gas
How do you improve the performance of vapor compressor refrigeration cycle?
In practical applications, vapor-compression refrigeration systems are the most commonly used refrigeration systems, and each system employs a compressor. In a basic vapor compression refrigeration cycle as shown in Figure 3.28, four major thermal processes take place as follows: • evaporation, • compression, • condensation, and • expansion.
What determines the pressure on the low pressure side of a refrigeration system?
the boiling point of refrigerant in a refrigeration or air conditioning system determines the pressure of the low side of the system
How many GPM in 1 ton in refrigeration system?
2.4
Evaporator in a refrigeration sistem?
The Evaporator is the part of a refrigeration system that absorbs heat. Its counterpart is the condenser which is used to remove heat that was absorbed in the evaporator.
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.
When you check system pressures to determine the performance of the refrigeration system its always a good idea to?
use recovery equipment to gain access to the system during testing
When you check system pressures to determine the performance of a refrigeration system it's always a good idea to?
use recovery equipment to gain access to the system during testing
When you check systems pressures to determine the performance of a refrigeration system its always a good idea to?
use recovery equipment to gain access to the system during testing
Pressure in a refrigeration system is changed where?
pressure in a refrigeration system is changed in the
When you check systems pressures to determine the performance of a refrigeration system it's always a good idea to?

Coefficient of performance of Vapor compression and Vapor absorption system?
For vapor compression: beta= Qdot / Ẇ =(h1-h4)/(h2-h1)
Why COP is used for evaluation of compression refrigeration system but not absorption refrigeration system?
cause its a gas

Where the refrigeration changes in a refrigeration system?
at the metering device before the evaporator
What does the evaporator do in the refrigeration system?
An evaporator in a refrigeration system works by passing warm air over it's coils.
What determines the pressure on the low pressure side of a refrigeration system?
the boiling point of refrigerant in a refrigeration or air conditioning system determines the pressure of the low side of the system
