Technical field
The utility model relates to a kind of LNG Power Vessel air conditioner refrigerating/heating system, specifically obtain air conditioner refrigerating/heating system that is energy-efficient, environmental protection with lower cost, particularly relate to one to make full use of ice conserve cold and reclaim LNG Power Vessel when running, LNG produces the low-temperature receiver of a large amount of colds as marine air-conditioning system in vaporescence, and a large amount of waste heats produced during LNG burning after vaporization are as the LNG Power Vessel air conditioner refrigerating of marine air-conditioning system thermal source and heating system, belong to air conditioner technology field.
Background technology
Along with the fast development of global economic integration, shipbuilding industry is full of life, but along with the fast development of shipbuilding industry, the thing followed is exactly the continuous deterioration of marine environment.At present, boats and ships mainly use diesel oil as fuel, and its main component is hydrocarbon and some other element, discharges a large amount of carbon dioxide, sulfide and dust in combustion process, causes huge destruction undoubtedly to marine environment.Therefore the noxious gas emission reduced in gas has become the key issue that environmental protect pollutes.Being the trend of the times of following boats and ships development using LNG as the Power Vessel of fuel, is the Power Vessel of main fuel at present with LNG, main adopts seawater to carry out heat exchange as thermal source with the LNG of-163 DEG C to be vaporized.A large amount of high-grade cold energy of LNG release is directly taken away by seawater, causes the significant wastage of the energy.The low temperature seawater producing a large amount of cold energy after absorbing LNG vaporization directly enters marine, makes surrounding waters be subject to serious cold pollution.
The boats and ships navigated by water on marine site are independently marine movable buildings, and often navigation is in different marine sites for it, and difference variation is larger, and in order to ensure the thermal comfort requirement of crewman and passenger, air-conditioning system is the requisite part of marine system.
At present, marine air-conditioner system uses conventional air-cooled or water-cooling system substantially.Application number is the air-conditioning system that patent discloses a kind of LNG Power Vessel of 201310454497.X, this system is primarily of expansion tank, inlet pipeline, several cabin fan coils, outlet pipeline, Load Regulation heat exchanger, refrigerant water pump, water bath type vaporizer forms, it utilizes water-bath room vaporizer to be vaporized by LNG, and the cold of release is carried out absorbing and utilizing, though this system utilizes LNG to vaporize the cold discharged, but directly use fresh water as refrigerating medium in this system, heat exchange is carried out with LNG in vapor-water heat exchanger, because when LNG vaporizes, heat exchange thermal gradient energy reaches 170 ~ 200 DEG C, may make to carry out the chilled water hyperabsorption cold of heat exchange thus freeze, whole system cannot normally be run, in this system, the evaporating capacity of LNG strictly must mate with air conditioner refrigerating amount simultaneously, especially when boats and ships are at the more NG of the less and marine power requirements of refrigerating capacity, normal required LNG evaporating capacity when running that this system can not meet boats and ships.
Application number is the LNG cold energy utilization device that patent discloses a kind of LNG Power Vessel of 201420183474.X, this system is primarily of the fuel tank storing liquefied natural gas, natural gas output channel in fuel tank is connected with the combustion gas input port of engine after the second heat exchanger through the first heat exchanger successively, first heat exchanger, first heating agent storage bin, cold energy releasing device to be end-to-end formation first cold energy use loop successively by pipeline, second heat exchanger, exhaust pipe of engine cooling jacket, second heating agent storage bin to be end-to-end formation second cold energy Releasing loop successively by pipeline, the composition such as circulating pump in order to heating agent in flow circuits is respectively provided with in first cold energy use loop and the second cold energy Releasing loop, although this system utilizes the pattern of two-stage cold recovery to reclaim the cold that LNG discharges, fully can absorb the cold of the release of LNG.But there is very large defect in this system on cryogenic energy utilization, it by the cryogenic energy utilization that absorbs in first-class heat exchanger in refrigerating chamber, with continuous service institute chilling requirement, there is larger difference because refrigerating chamber runs for the first time, burst size when refrigerating chamber chilling requirement in this system and LNG vaporize also exists larger difference, create and release cold and serious not the mating of chilling requirement, cause LNG evaporating capacity not enough, affect the demand to LNG evaporating capacity when ship power system normally runs; In this secondary cold recovery system, the cold of absorption is used for cooling the jacket water after heating up in Ship Power Equipment.In existing many technology, recycling for engine of boat and ship cooling jacket water waste heat is a lot, and the cold discharged from LNG is used for cooling jacket water by this system, obvious uneconomical environmental protection, not only waste the cold of LNG release, waste the heat in cooling jacket water.
