In a vapour
compression refrigeration system, liquid to suction heat exchanger is used to
________ .
वाष्प संपीड़न प्रशीतन प्रणाली में, तरल से सक्शन हीट एक्सचेंजर का उपयोग ________ के लिए किया जाता है।
keep the COP
constant
prevent the liquid refrigerant from entering the compressor
sub-cool the
liquid refrigerant leaving the condenser
sub-cool the
vapour refrigerant from the evaporator
sub-cool the
liquid refrigerant leaving the condenser
1 – 2 heat
exchanges
4 – 5 heat
exchanges
When the
refrigerant leaves condenser as sub-cooled liquid. The sub-cooling process is
shown by 4-5 in the above Figure. Sub-cooling increases the cooling capacity
and will prevent entering any vapour (bubbles) to the expansion valve
Hence, the correct option is (C).
&Key Points:-
Benefit of
liquid to suction heat exchanger :
●It provide
sub cooling to the liquid to the refrigerant prior to it entering the expansion
valve, which helps to operate with greater stability.
●The added
sub cooling which provided to the liquid refrigerant increase the efficiency of
the system.
