bigger
smaller
equal
smaller/bigger depending on capacity
ineffective refrigeration
high power consumption
freezing automatic regulating valve
corrosion of whole system
it permits higher speeds to be used
it permits complete evaporation in the evaporator
it results in high volumetirc and mechanical efficiency
all of the above
Temperature of medium being cooled must be below that of the evaporator
Refrigerant leaves the condenser as liquid
All solar thermally operated absorption systems are capable only of intermittent operation
frost on evaporator reduces heat transfer
increases COP
decreases COF
COP remains unaltered
other factors decide COP
