Classification: CPC F | IPC F

Claim 19:
20. A heated suction line accumulator, comprising:
a tank defining a first interior cavity;
a refrigerant input orifice extending through a sidewall of the tank and being configured to receive input refrigerant from outside the tank;
an intermediate tube defining a second interior cavity, the intermediate tube being disposed inside of the first interior cavity and including at least one first aperture extending through a sidewall of the intermediate tube;
a heating line disposed inside of the tank and including a plurality of coils wound around the intermediate tube, the heating line being configured to receive a heated fluid;
an inner tube disposed in the second interior cavity, the inner tube being configured to convey the input refrigerant in the intermediate tube outside of the tank as output refrigerant;
a pump in fluid communication with the heating line;
at least one temperature sensor associated with the heated suction line accumulator and being configured to sense a temperature of the output refrigerant; and
a controller configured to modulate a speed of the pump if the temperature of the output refrigerant is outside of a predetermined temperature range, to thereby control a flow rate of the heated fluid introduced into the tank via the heating line.
