Absorption type refrigerator

Abstract

The invention provides an absorption refrigerating machine for heating the refrigerant for regeneration by using two kinds of the exhaust at a different temperature as a heat source, which is a device structure optimal to be used for heating, besides a purpose of cooling. This absorption refrigerating machine is provided with a high- temperature regenerator 1, a low-temperature regenerator 2, a third regenerator 3, a condenser 4, a second condenser 5, an evaporator 6, and an absorber 7 so that cooling operation such as cooling is enabled by using the discharged hot-water supplied from a discharged hot-water supply pipe 23 and the high- temperature exhaust gas supplied from a high-temperature exhaust gas supply pipe 21. In this absorption refrigerating machine, heating operation such as heating is enabled by providing an absorption liquid pipe wherein an opening / closing valve 13 is interposed to supply the absorption liquid and the refrigerant steam, which are separated by heating in the high-temperature regenerator 1 by using the only high-temperature exhaust gas supplied form the high- temperature exhaust gas supply pipe 21 as a heat source, to the absorber 7 and providing a refrigerant pipe wherein an opening / closing valve 14 is interposed.

Description

technical field [0001] The invention relates to an absorption refrigerator (including an absorption cold and warm water machine) equipped with two heat sources for heating the absorption liquid and generating refrigerant vapor Background technique [0002] Two types of waste heat recovery refrigerant absorption chillers are known in use today. These two types of waste heat include, for example, high-temperature waste heat of about 650°C in gas exhaust gas discharged from a gas engine for power generation, and low-temperature waste heat of about 90°C in engine cooling water. [0003] As a problem to be solved, even in an absorption chiller that uses two types of waste heat at different temperatures as a heat source to heat and regenerate refrigerant, it is necessary to provide not only cooling applications such as air conditioning, but also heating such as heating. the most suitable device structure.
