Background technology
In recent years, China's domestic air conditioning becomes increasingly popular in city.2001 to 2013, China Domestic air conditioning market
Yield is incremented by with the trend of annual average compound growth rate 17.29%, and China's domestic air conditioning yield in 2013 is 130,570,000.In the summer
Season, its main function was to make room temperature lowering, and the condensation heat of air-conditioning system is directly discharged in air when family expenses air conditioner refrigerating, and
It is not used.Substantial amounts of condensation heat is discharged to atmospheric environment when refrigeration unit is run under air conditioning condition, usual condensation heat can
Up to 1.15~1.3 times of refrigerating capacity.Substantial amounts of condensation heat is directly discharged into air, loses in vain, causes larger energy waste,
Distributing and raising ambient temperature for these heats, causes serious environmental thermal pollution, so, in order to save the energy and guarantor
Retaining ring border, air conditioner afterheat, which recycles, just seems necessary.
Water is to maintain life and the primary demand of health, and although area that the earth has 71% is covered by water, but fresh water
Resource is extremely limited.Current global freshwater resources only account for the 2.5% of its total Water, wherein more than 70% is frozen in south
In the ice sheet of pole and the arctic, plus the alpine glacier and permafrost accumulated snow being difficult by, the freshwater resources for having 86% are difficult by.People
The freshwater resources that class really is able to utilize are the parts in rivers and lakes and underground water, only account for the 0.26% of earth total Water.
At present, there are 1/6 population, about people's water shortage more than 1,000,000,000 in the whole world.Expert's estimation, will be more than 25 to world's water shortage population in 2025
Hundred million.Again due on the earth fresh water be distributed in region, temporal lack of uniformity, and pollution of the mankind to water source, make fresh water
Available quantity is not only restricted, and is drastically reduced.Water shortage problem has been the social sustainable of whole world facing

The content of the invention
The invention discloses a kind of air-conditioning of Winter-summer dual purpose and desalinization co-production, summer using air-conditioning used heat or
Winter carries out low temperature multiple-effect distillation to produce fresh water using condensation heat caused by air-conditioning, improves energy utilization rate, reduces light
To change the cost of seawater, and reduce environmental thermal pollution, while fresh water yield is improved using temperature difference of seawater, the summer in winter can produce water,
Practicality is high, has good economic benefit.
A kind of air-conditioning of Winter-summer dual purpose and desalinization co-production, comprise the following steps：
Using the condensation heat during air conditioner refrigerating or the condensation heat in heating operations as thermal source, using low temperature multiple-effect distillation
Method carries out desalinization；
The fresh water steam of a upper effect enters next effect and condensed, and the temperature of fresh water steam reduces by effect, last effect production
The fresh water vapor (steam) temperature gone out is less than 20 DEG C；
Take the fresh water steam of last effect output of the seawater condensing of the first source of seawater；
The seawater of the second source of seawater is taken to be treated as seawater to be diluted by fresh water and the concentrated seawater preheating of its residual effect output light
Change seawater, the temperature of second source of seawater is higher than the temperature of the first source of seawater.

The ocean temperature of one seawater inlet pipe.
In present system, the condensation module using the condenser of air-conditioning as the first effect distillation unit, and kind of refrigeration cycle
Unit and heating cycling element share same condenser, so that system is integrally more compact, reduce overall volume；By last
Imitate the condensation of fresh water steam and the preheating of seawater to be diluted is entered by the seawater of different two heat exchange units and different temperatures
Row heat exchange, last effect fresh water steam is condensed using low temperature seawater, last effect fresh water vapor (steam) temperature is set relatively low, so as to
In the case where the first effect is temperature-resistant, the effect number of distillation unit is added, improves fresh water yield；And it is passed through the second seawater to enter
The ocean temperature to be diluted of pipe is higher than the ocean temperature for being passed through the first seawater inlet pipe, is passed through the seawater to be diluted of the second seawater inlet pipe
Temperature it is higher, then required time and energy consumption are fewer when being preheated, it is possible to reduce preheating time, improve sea to be diluted
Temperature after the preheating of water, further improve efficiency of energy utilization and fresh water yield.
General sea water advanced more than 10 meters ocean temperatures are less protected from environmental, overall than relatively stable about 13~18
℃；Surface seawater is then affected by environment larger, and general summer is about 27~35 DEG C, and winter is 0~7 DEG C, due to winter and summer
Seawater water temperature can change, and can use two circuits, in the winter time with summer respectively to the first seawater inlet pipe and the second seawater inlet pipe
