US 2025/0189178 A1 · ABSORPTION TYPE CHILLER

Abstract

An absorption type chiller includes an evaporator; an absorber which generates an absorption liquid by mixing the refrigerant evaporated in the evaporator with an absorbent; a regenerator which heats the absorption liquid supplied from the absorber; a condenser to which refrigerant generated in the regenerator is supplied; and a heat pipe which is arranged in at least one of the evaporator and the absorber and elongated. The heat pipe includes a plurality of protrusions which protrude from a surface of the heat pipe and are arranged in a longitudinal direction and a peripheral direction of the heat pipe. A distance between the plurality of protrusions arranged in the peripheral direction of the heat pipe is smaller than a distance between the plurality of protrusions arranged in the longitudinal direction of the heat pipe.

An absorption chiller comprising:

an evaporator configured to carry and evaporate refrigerant therein;
an absorber configured to generate an absorption liquid by mixing the refrigerant from the evaporator with an absorbent;
a regenerator configured to heat the absorption liquid supplied from the absorber;
a condenser configured to receive the refrigerant from the regenerator;
and
a heat pipe that is arranged in at least one of the evaporator or the absorber and extends in a longitudinal direction, the heat pipe comprising a plurality of protrusions that protrude from a surface of the heat pipe and are arranged in the longitudinal direction and a peripheral direction of the heat pipe,
wherein a distance between two adjacent protrusions of the plurality of protrusions in the peripheral direction is less than a distance between two adjacent protrusions of the plurality of protrusions in the longitudinal direction.
