Problems solved by technology

Therefore, during the period when the refrigerant pump is stopped, since the heat exchange between the refrigerant and the brine is not performed, the temperature of the brine fluctuates, so it is difficult to suppress the temperature fluctuation of the brine and supply the brine to the heat load stably. The problem

Abstract

The present invention provides an absorption type refrigerator which realizes refrigerant pump protection and can restrain temperature variation of refrigerant. An absorption type cold water and warm water dispenser (100) comprises the following components: a high-temperature regenerator (5), a low-temperature regenerator (6), a condenser (7), an evaporator (1) and an absorber (2). The invention is characterized in that the evaporator (1) is provided with the following components: a refrigerant pump (P3) which pumps the refrigerant that is stored in a refrigerant storing part (1B) in the evaporator; a refrigerant pipe (34) for connecting the refrigerant pump (P3) with a dispenser (1C) which is configured above a heat transfer pipe (14A) of the cold / hot water pipe (14); a branch pipe (35) which is branched from the refrigerant pipe (34) and is connected below the heat transfer pipe (14A); and a float valve (41) which adjusts the amount of refrigerant which circulates in the branch pipe.

Description

technical field [0001] The invention relates to a liquid level control technology of refrigerant stored in an evaporator. Background technique [0002] A generally known absorption refrigerating machine includes: a regenerator that heats an absorption liquid containing a refrigerant and vaporizes and separates the refrigerant from the absorption liquid; a condenser that cools the refrigerant separated by the regenerator to its condensing; the evaporator, which spreads the refrigerant condensed by said condenser on heat pipes passing through a brine, and evaporates it in a shell under low pressure; and the absorber, which causes the The refrigerant evaporated by the evaporator is absorbed by the absorption liquid (for example, refer to Patent Document 1). Such an absorption refrigerating machine is equipped with a refrigerant pump that pumps up the refrigerant stored in the refrigerant storage unit in the casing, and by continuously operating the refrigerant pump, the refrig...
