CHAPTER 6 REFRIGERATION
HEAT AND REFRIGERATION PRINCIPLES
A quantity of heat required to change the temperature of 1 pound
of any substance 1°F compared to water.
Sensible heat is the increase of temperature, and latent heat is the
change of state.
Decreases its volume in proportion to the increase of pressure.
Condense into a liquid.
MECHANICAL REFRIGERATION SYSTEMS
Reciprocating, rotary, and centrifugal.
The external is positioned on the outside of the crankcase.
The inaccessibility or repair and low capacity.
Dry or flooded.
Refrigerators and window air conditioners.
To determine the presence and amount of vapor in the refrigerant.
Chloroflorocarbons and hydrochloroflorocarbons.
Reduced efficiency, mechanical problems, and dangerous
