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 device (such as a solar water heater, cogeneration device) connected to the low heat source regenerator. use efficiently
In addition, there may be fluctuations in the temperature of the brine supplied from the evaporator to the heating load cycle

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 block diagram of the absorption-type hot-water machine (absorption-type refrigerator) 100 of this embodiment. The absorption type chiller 100 is an exhaust heat recovery type (so-called "Joint Power Supply Chain") absorption chiller with a low heat source regenerator, in which water is used as a refrigerant and water is used as an absorption Using lithium bromide (LiBr) aqueous solution, the low heat source regenerator heats the absorption liquid by hot water at a lower temperature (eg, about 80°C) generated by a heat source generating device (eg, solar water heater, cogeneration device).

[0041] like figure 1 As shown, the absorption chiller 100 has an evaporator 1, an absorber 2 arranged side by side with the evaporator 1, an evaporator-absorber cylinder 3 that accommodates the evaporator 1 and the absorber 2, and has a gas combu...

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 using hot water or the like as a heat source. Background technique [0002] In general, there is known an absorption refrigerator having a low heat source regenerator, a high temperature regenerator, a low temperature regenerator, an evaporator, a condenser, and an absorber, and these devices are respectively connected by piping. A circulation path of the absorption liquid and the refrigerant is formed (for example, refer to Patent Document 1). In such an absorption chiller, single-effect operation, single-effect operation, or double-effect operation can be switched and operated according to the load amount of heat load, such as an air conditioner connected to an evaporator via a brine pipe, and the single-effect operation can be operated. The absorbing liquid is heated using the hot water supplied to the low-heat source regenerator as a heat source, and t...
