Absorbing type refrigerator

Abstract

The invention provides an absorbing type refrigerator capable of performing heat recovery in low-temperature warm water. The absorbing type refrigerator is provided with: a high-temperature regenerator, a low-temperature regenerator, an evaporator, a first condenser, a first absorber, a heat resource warm water low-pressure regenerator performing condensation of the absorbing liquid via using warm water to heat absorbing liquid to evaporate and separate a refrigerant, absorbing liquid and refrigerant path are respectively formed via tubing connections, the absorbing type refrigerator is also provided with: a heat source warm water high-pressure regenerator performing condensation of the absorbing liquid via using the warm water to heat the absorbing liquid to evaporate and separate a refrigerant; and a second absorber making the absorbing liquid condensed by the heat source warm water high-pressure regenerator absorb refrigerant steam evaporated by the heat source warm water low-pressure regenerator; the second absorber and the heat source warm water low-pressure regenerator are received in a single heat source regenerator absorber cavity, and a recycling path making the absorbingliquid additionally recycle is disposed between the second absorber and the heat source warm water high-pressure regenerator.

Description

technical field [0001] The present invention relates to an absorption refrigerating machine including a heat source regenerator that uses warm water or the like as a heat source. Background technique [0002] In general, an absorption refrigerating machine is known in which a heat source regenerator, a high-temperature regenerator, a low-temperature regenerator, an evaporator, a condenser, and an absorber are provided, and these devices are connected by piping to form an absorption liquid and an absorber, respectively. Refrigerant circulation path (for example, refer to Patent Document 1). In such an absorption refrigerating machine, the operation can be selected from a single-effect operation and a double-effect operation, wherein the single-effect operation is an operation in which the warm water supplied to the heat source regenerator is used as a heat source to heat and regenerate the absorption liquid. Mode, one double effect operation is an operation mode in which the...

Problems solved by technology

However, in the conventional structure, in order to recover heat from warm water at a low temperature (for example, about 60°C), it is necessary to change the operating conditions such as greatly reducing the cooling water temperature, and it is impossible to achieve sufficient energy saving.
