Description
Technical field
The present invention relates to desalination technology, more particularly to a kind of Winter-summer dual purpose air-conditioning and flat flow desalinization coproduction
Method and system.
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 problem of development.This severe with water form and current conditions, proposition and the application of desalinization have greatly existing
Sincere justice.
