Ultrasonic wave and structural heat pipe comprehensive-strengthened absorption refrigerator and refrigeration method

Abstract

The invention relates to an ultrasonic wave and structural heat pipe comprehensive-strengthened absorption refrigerator. The absorption refrigerator comprises a condenser, a generator, an evaporator, an absorber, a high-pressure cavity and a low-pressure cavity; the condenser and the generator are positioned in the high-pressure cavity; the evaporator and the absorber are positioned in the low-pressure cavity; and the condenser, the generator, the evaporator and the absorber are all provided with heat pipes. The absorption refrigerator further comprises an ultrasonic transducer tightly bonded on the high-pressure cavity; and the heat pipes are structural heat pipes with inner and outer groove surface structures. The invention further relates to an ultrasonic wave and structural heat pipe comprehensive-strengthened absorption refrigeration method; the high-pressure cavity generates a condensation effect through ultrasonic wave and structural heat pipe comprehensive strengthening; and the low-pressure cavity uses the structural heat pipe bundle for strengthening evaporation and absorption effects. The absorption refrigerator is simple and feasible, is obvious in effect, can be popularized on the market, strengthens the heat and mass transfer effect, and belongs to the technical field of absorption refrigerators.

Description

technical field [0001] The invention relates to an absorption refrigerating machine, in particular to an absorption refrigerating machine and a refrigerating method comprehensively strengthened by ultrasonic waves and structural heat pipes. Background technique [0002] In recent years, absorption chillers driven by clean energy have received more and more attention, because compared with traditional compression air conditioners, absorption chillers can be driven by low-grade hot water or other industrial waste heat energy, and use lithium bromide As a refrigerant, aqueous solution has the advantages of saving energy and protecting the environment. [0003] At present, the main problem of the absorption chiller is that the evaporation capacity of the refrigerant water of the generator is relatively poor, and the absorption capacity of the refrigerant water of other devices such as the condenser is also slightly insufficient, which makes the heat exchange efficiency of the en...
