Heat exchanges in a refrigeration machine
Gap-fill exercise
Complete the following text. Click "Correction" when you are done.
In a refrigeration machine, heat exchange takes place as follows:
- the temperature of the fluid at low pressure is lower than the temperature of
it condenses
the ambient
the cold chamber
the compressor
the fluid at high pressure
the throttling valve
. As it evaporates, it extracts heat from it.
- the temperature of
it condenses
the ambient
the cold chamber
the compressor
the fluid at high pressure
the throttling valve
is higher than
it condenses
the ambient
the cold chamber
the compressor
the fluid at high pressure
the throttling valve
temperature. As
it condenses
the ambient
the cold chamber
the compressor
the fluid at high pressure
the throttling valve
, it gives off heat to the outside air
For these exchanges to be possible, two components modify the pressure of the refrigerant:
-
it condenses
the ambient
the cold chamber
the compressor
the fluid at high pressure
the throttling valve
raises the pressure, thereby increasing its temperature.
- by lowering the pressure,
it condenses
the ambient
the cold chamber
the compressor
the fluid at high pressure
the throttling valve
drops its temperature.
