Abstract
An absorption refrigeration machine may include a first regenerator for primarily regenerating an absorbing liquid absorbing a refrigerant; a second regenerator for secondarily regenerating the absorbing liquid primarily regenerated from the first regenerator; an auxiliary absorber provided with the second regenerator, to allow an auxiliary absorbing liquid to absorb the refrigerant; and an auxiliary regenerator for regenerating the auxiliary absorbing liquid carrying the refrigerant in the auxiliary absorber.
Claims17
An absorption refrigeration machine comprising:
- a first absorber configured to cause a first absorbing liquid to absorb a refrigerant;
- a first regenerator coupled to the first absorber to receive the first absorbing liquid, wherein the first regenerator is configured to cause the first absorbing liquid to release at least a portion of the absorbed refrigerant;
- a second regenerator coupled to the first regenerator to receive the first absorbing liquid, wherein the second regenerator is configured to be selectively activated to cause the first absorbing liquid to release another portion of the absorbed refrigerant;
- a second absorber coupled to the second regenerator, wherein when the second regenerator is activated, the second absorber is configured to cause a second absorbing liquid to absorb the refrigerant;
- a third regenerator coupled to the second absorber, wherein the third regenerator is configured to receive the second absorbing liquid and cause the second absorbing liquid to release the absorbed refrigerant;
- a condenser configured to capture the released refrigerant from the first regenerator and the third regenerator;
- and
- a flash tank coupled to the condenser, the first absorber and the second absorber wherein the flash tank is configured to receive the refrigerant from the condenser and to forward the received refrigerant to at least one of the first absorber or the second absorber.

A method for controlling an absorption refrigeration machine, the method comprising:
- removing, by a first regenerator included in the absorption refrigeration machine, a first portion of a dissolved refrigerant from a first absorbing liquid, wherein the refrigerant is absorbed by the first absorbing liquid in a first absorber included in the absorption refrigeration machine, and wherein a second regenerator included in the absorption refrigeration machine selectively removes a second portion of the dissolved refrigerant from the first absorbing liquid;
- determining whether a second absorbing liquid is flowing between a second absorber and a third regenerator included in the absorption refrigeration machine;
- and
- controlling a flow of a warming fluid into the second regenerator based on whether the second absorbing liquid is flowing between the second absorber and the third regenerator,
- wherein the second regenerator includes a first tube that transports the warming fluid when the warming fluid flows into the second regenerator,
- wherein the absorption refrigeration machine further comprises a second tube that bypasses the second regenerator and transports the warming fluid away from the first tube when the warming fluid does not flow into the second regenerator, and
- wherein controlling the flow of the warming fluid into the second regenerator includes:
- directing the warming fluid to the first tube and into the second regenerator when the second absorbing liquid flows between the second absorber and the third regenerator, and
- directing the warming fluid to the second tube and away from the second regenerator when the second absorbing liquid does not flow between the second absorber and the third regenerator.

An absorption refrigeration machine comprising:
- a regenerator configured to receive a first absorbing liquid, wherein the regenerator is configured to be selectively activated to cause the first absorbing liquid to release a refrigerant;
- a tray configured to capture the first absorbing liquid from the regenerator;
- an absorber coupled to the regenerator and storing a second absorbing liquid;
- and
- a valve to direct a warming fluid to one of the regenerator or a tube that bypasses the regenerator,
- wherein when the regenerator is activated to cause the first absorbing liquid to release the refrigerant, the absorber is configured to cause the second absorbing liquid to absorb the refrigerant, wherein, when the valve directs the warming fluid to the regenerator, a heat exchange between the first absorbing liquid and the warming fluid causes the first absorbing liquid to release the refrigerant, and wherein the heat exchange does not occur when the valve directs the warming fluid to the tube that bypasses the regenerator.
