Problems solved by technology

Therefore, directly passing the flue gas into the generator will cause certain safety risks to the overall lithium bromide absorption refrigeration device and even the normal ocean navigation of the cruise ship.
Therefore, this waste heat utilization scheme for automobile engines is not applicable to cruise ships

Embodiment approach 1

[0028] Combine figure 1 , This embodiment includes high-pressure generator 6, low-pressure generator 7, low-pressure generator 8, condenser 12, evaporator 19, evaporator 13, absorber 18, absorber 17, generator pump 21, generator pump 15, Heat exchanger 23, heat exchanger 20, heat exchanger 22, heat exchanger 14, heat exchanger 9, heat exchanger 16, heat exchanger 7, three-way cock 30, three-way cock 5, three-way cock Valve 10, flue gas heat exchanger 1, high temperature heat source water pump 2, high temperature heat source water tank 3, turbocharger 28, two-stage intercooler, cylinder liner cooling water tank 24, cylinder liner cooling water pump 25, diesel engine cylinder liner cooling cavity 26, and the connecting pipelines and throttle valves of various components.

[0029] The specific implementation of this program is as follows:

[0030] The steam outlet of the high-pressure generator 6 is connected to the inlet of the steam heat exchange tube bundle in the low-pressure gen...

specific Embodiment approach 2

[0040] Combine figure 2 This embodiment is described. The difference between this embodiment and the first embodiment is that the heat exchanger 4 for heating and heating general-purpose water is reduced by rationally setting the pipeline, and the overall volume of the unit is reduced. The outlet of the high temperature condensate heat exchange tube bundle in the low pressure generator 8 is connected to the three-way plug valve 30 via the heat exchanger 9. The three-way plug valve 30 divides the high-temperature condensate pipeline into two paths, one is connected to the three-way plug valve 5, and the other is connected to the low-pressure generator 8 dilute solution inlet pipeline. The high-temperature steam outlets in the low-pressure generator 7 and the low-pressure generator 8 are connected to the three-way plug valve 5 through a steam tube bundle. The low-pressure generator 7, the low-pressure generator 8 and the condenser 12 are all in a single cavity. The three-way p...

Abstract

The invention aims to provide an efficient regeneration type lithium bromide absorbing refrigerating and heating system for a cruise. Water serves as a refrigerating agent, a lithium bromide solutionserves as an absorbing agent, and a high-pressure generator, a first low-pressure generator, a second low-pressure generator, a condenser, a first evaporator, a second evaporator, a first absorber, asecond absorber, a first generator pump, a second generator pump, first to seventh heat exchangers, first to third three-way plug valves, a gas-gas heater, a high-temperature heat source water pump, ahigh-temperature heat source water tank, a turbocharger, a two-section type intercooler, a cylinder sleeve cooling water tank, a cylinder sleeve cooling water pump, a diesel engine cylinder sleeve cooling cavity, connection pipelines and throttling valves of all the components, and the like are included. The system can meet the refrigerating or heating requirements of the cruise under different working conditions and environments.

Description

Technical field [0001] The invention relates to a lithium bromide absorption refrigeration device, in particular to a lithium bromide absorption refrigeration device for cruise ships. Background technique [0002] The design of the refrigeration system in the cabin of a cruise ship is essential. At present, the compression refrigeration device is the mainstream product of the marine refrigeration device, but it will consume a large amount of electric power and seriously consume the power generation of the main engine of the ship. The marine air conditioning waste heat absorption refrigeration technology uses the waste heat of the diesel engine to drive, which effectively avoids the deficiencies of the compression refrigeration device. At the same time, take the Wärtsilä 12V46ME medium-speed diesel engine (the main engine is commonly found on the "Ocean" series of cruise ships) as an example, the effective work only accounts for 50.16% of the heat released by fuel combustion, and...
