能源和环境是当今人类面临的两大问题。目前,化石燃料是人类生产.生活的主要能源。随着全球能源使用量的增长,及不科学使用,化石燃料等不可再生能源将日益枯竭,并对环境产生严重影响。我国正遭遇经济高速发展带来的后遗症,环境污染,主要包括大气污染、水污染与土壤污染三方面。近年,随着PM2.5与雾霾逐渐受到重视,大气污染成为国人关注焦点。在我国北方地区正在进行一场无煤化的革命Energy and the environment are two major problems facing humanity today. At present, fossil fuels are the main source of energy for human production and life. With the growth of global energy use and unscientific use, non-renewable energy sources such as fossil fuels will become increasingly depleted and have a serious impact on the environment. China is experiencing the aftermath of rapid economic development. Environmental pollution mainly includes air pollution, water pollution and soil pollution. In recent years, with the increasing attention of PM2.5 and smog, air pollution has become the focus of attention of the Chinese people. A revolution without coalification is underway in northern China
热泵作为一种清洁的可再生能源技术,在供暖行业中有着举足轻重的作用,而传统热泵技术有其各自的局限性:As a clean renewable energy technology, heat pumps play an important role in the heating industry, and traditional heat pump technology has its own limitations:

发明内容Summary of the invention
本发明要解决的技术问题是克服现有流态冰制冷换热器的缺点,而提供一种流态冰蒸发器及使用该流态冰蒸发器的空调***,本发明可以利用江河湖海的水源,利用有以冰水混合物的 形式排放,极大的减少热泵用水量,本技术是热泵***的革命。The technical problem to be solved by the present invention is to overcome the shortcomings of the existing fluid ice refrigeration heat exchanger, and to provide a fluid ice evaporator and an air conditioning system using the fluid ice evaporator, the invention can utilize the rivers and lakes The water source is discharged in the form of a mixture of ice and water, which greatly reduces the water consumption of the heat pump. This technology is a revolution of the heat pump system.
本发明流态冰蒸发器所采用的是过冷技术,将一定浓度的溶液,冷却到一定过冷度的温度,利用盐溶液的析冰现象,在溶液中形成冰晶,下面介绍一下析冰现象的原理。The fluid ice evaporator of the invention adopts the supercooling technology, and cools a certain concentration of the solution to a certain degree of subcooling temperature, and forms ice crystals in the solution by using the ice forming phenomenon of the salt solution, and the following describes the ice forming phenomenon. The principle.
如图1所示,它是溶液浓度相平衡图,在图中横坐标表示溶液浓度,纵坐标表示温度,WE为析冰线,EG为析盐线,E点为共晶点。As shown in Fig. 1, it is a solution concentration phase equilibrium diagram. In the figure, the abscissa indicates the solution concentration, the ordinate indicates the temperature, WE is the precipitation line, EG is the precipitation line, and point E is the eutectic point.
1、析冰线、析盐线上部是溶液区;TE线与析冰线之间区域为冰+溶液共存区;TE线与析盐线之间的区域为溶质+饱和溶液共存区;析冰线与析盐线上部为溶液区;TE线下部为冰+溶质的固体共存区。1. The ice-dissolving line and the salt-dissolving line are solution zones; the area between the TE line and the ice-dissolving line is the ice + solution coexistence zone; the area between the TE line and the salt-dissolving line is the solute + saturated solution coexistence zone; The line on the line and the salt line is the solution zone; the lower part of the TE line is the solid coexistence zone of ice + solute.
2、每种浓度的溶液都对应一个冰晶(水冰)析出温度,当溶液温度降至析冰温度时就可以连续析出冰晶。2. The solution of each concentration corresponds to the precipitation temperature of an ice crystal (water ice), and the ice crystal can be continuously precipitated when the temperature of the solution falls to the ice-precipitation temperature.
3、溶液析出冰晶时放出热量,使溶液温度微量增加,溶液温度也微量上升,这种析出冰晶过程中溶液的特殊性就使溶液在冰晶析出过程中不易粘结在制冰管道上。3. When the solution precipitates ice crystals, the heat is released, so that the temperature of the solution is slightly increased, and the temperature of the solution is also slightly increased. The particularity of the solution during the precipitation of the ice crystal makes the solution not easily adhere to the ice making pipeline during the ice crystal precipitation process.
4、流态冰机组可用溶液为盐类(海水、NaCl盐溶液等)、醇类(甲醇、乙醇、丙三醇、丙二醇、乙二醇溶液等)4, the flow ice unit can be used as a salt (sea water, NaCl salt solution, etc.), alcohol (methanol, ethanol, glycerol, propylene glycol, ethylene glycol solution, etc.)
根据乙二醇的性质,本技术采用乙二醇作为载冷剂,此时整个循环的乙二醇溶液为固液混合状态,当混合溶液流经体积较大的蓄能池时,溶液中的冰晶自然上浮,达到冰晶与乙二醇溶液分离的目的。According to the nature of ethylene glycol, the technology uses ethylene glycol as a brine carrier. At this time, the entire circulating ethylene glycol solution is in a solid-liquid mixed state. When the mixed solution flows through a large volume storage tank, the solution The ice crystals naturally float up to achieve the purpose of separating the ice crystals from the ethylene glycol solution.
