Цитат:
The practical effects of heat exchanger size can be summarized as follows:
Larger evaporator :
(1) Higher suction pressure to give denser gas entering the compressor and therefore a greater mass of gas for a given swept volume, and so a higher refrigerating duty;
(2) Higher suction pressure, so a lower compression ratio and less power for a given duty.
Larger condenser :
(1) Lower condensing temperature and colder liquid entering the expansion valve, giving more cooling effect;
(2) Lower discharge pressure, so a lower compression ratio and less power.
