Single and double effect absorption refrigerator and operation control method therefor

Abstract

To prevent thermal loss by preventing the self-flash of the rare absorption liquid flowing into a low heat source regenerator even when the heat source is not supplied to the low heat source regenerator. A second rare absorption liquid pump P2 is mounted on the side of a low heat source regenerator 9 of a rare absorption liquid pipe 15 connecting an absorber 2 and the low heat source regenerator 9 through a first rare absorption liquid pump P1 and the like; and the upstream side of the second rare absorption liquid pump P2 and the upstream side of an intermediate absorption liquid pump P3 of an intermediate absorption liquid pipe 16 connecting the low heat source regenerator 9 and a high-temperature regenerator 5 through the intermediate absorption liquid pump P3 are communicated with each other through a bypass pipe 17. In the low heat source regenerator 9 with an intermediate absorption liquid pipe 16 connected to its bottom, a heat transfer pipe 9B is mounted under a sprayer 9A. The start / stop of the second rare absorption liquid pump P2 is controlled on the basis of a temperature of the heat source flowing into the low heat source regenerator 9 or discharged from the low heat source regenerator 9, and a temperature of the brine flowing into an evaporator 1 or discharged from the evaporator 1, and a rotating speed of the second rare absorption liquid pump P2 is controlled on the basis of the temperature of the brine.

Description

[0001] This application is a divisional application filed on August 30, 2005, with application number 200510099456.9, and titled "Single-double-effect absorption refrigerator and its operation control method". technical field [0002] The invention relates to a single-effect absorption refrigerator (including an absorption water cooler and a heater). Background technique [0003] For example, this type of absorption refrigerating machine includes a well-known single-double-effect absorption refrigerating machine 100X, the configuration of which is shown in FIG. 5 . It includes gas burners 4 to radiate combustion heat. The high-temperature regenerator 5 is provided so as to use the combustion heat radiated from the gas burner 4 as a heat source, thereby heating the absorbing liquid to evaporate the refrigerant, respectively. The low-temperature regenerator 6 of the double-effect regenerator is also provided so as to use the refrigerant vapor supplied from the high-temperatur...

AI Technical Summary

Problems solved by technology

In this case, the leaked warm water discharge can heat the absorption liquid in the low heat source regenerator 9, and excessively condense the absorption liquid to make it crystallize, which is a problem
