Problems solved by technology

[0006] Since the stop operation at the time of switching the operation mode as described above blocks the supply of hot water to the low heat source regenerator, it hinders the recovery of the heat discharged from the heat source generating de

Embodiment Construction

[0039] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0040] figure 1 It is a schematic configuration diagram of an absorption chiller (absorption chiller) 100 according to the present embodiment. The absorption chiller 100 is an exhaust heat recovery type (so-called "Jenelink") absorption chiller with a low heat source regenerator, in which water is used as a refrigerant, and water is used as a refrigerant. Lithium bromide (LiBr) aqueous solution is used as the absorption liquid, and the low heat source regenerator heats the absorption liquid with relatively low temperature (for example, about 80°C) hot water generated by a heat source generator (for example, solar water heater, cogeneration device).

[0041] Such as figure 1 As shown, the absorption cold and hot water machine 100 has: an evaporator 1, an absorber 2 arranged side by side with the evaporator 1, an evaporator-absorber cylinder 3 for accommodating the ev...

Abstract

An absorption refrigerator will not stop and can operate continuously even if an operation mode is switched. The absorption cold-hot water machine (100) is provided with a low heat source regenerator (9), a high temperature regenerator (5), a low temperature regenerator (6), an evaporator (1), a first condensator (7), a second condensator (10) and an absorption device (2), which are connected through piping to form circulation paths of absorption liquid and refrigerant for single effect operation and single/double effect operation or double effect operation, the single effect operation heats the absorption liquid by using the hot water supplied to the low heat source regenerator as the heat source, the single/double effect operation or the double effect operation heats the absorption liquid by using a gas burner (4) of the high temperature regenerator as the heat source, a discharging side of the absorption device is connected with the high temperature regenerator through an absorption liquid feed pipe (65) which is provided with a feed on-off valve (66) and supplies dilute absorption liquid to the high temperature regenerator.

Description

technical field [0001] The present invention relates to an absorption refrigerator having a low heat source regenerator that uses hot water or the like as a heat source. Background technique [0002] In general, there is known an absorption refrigerating machine that includes a low-heat source regenerator, a high-temperature regenerator, a low-temperature regenerator, an evaporator, a condenser, and an absorber, and these devices are connected to each other by piping. A circulation path for the absorption liquid and the refrigerant is formed (for example, refer to Patent Document 1). In such an absorption refrigerator, it is possible to switch between single-effect operation and single-effect operation or double-effect operation according to the load of heat load such as an air conditioner connected to the evaporator through a salt water pipe. The hot water supplied to the low-heat source regenerator is used as a heat source to heat the absorption liquid, and the single-eff...
