Description

一种太阳能驱动的温湿度独立控制空调系统A solar powered air conditioning system with independent temperature and humidity control

技术领域:Technical field:

本发明属于空调领域,涉及一种太阳能空调系统,尤其涉及一种太阳能驱动的温湿度独立控制空调系统。The invention belongs to the field of air conditioning, relates to a solar energy air conditioning system, and in particular relates to a solar energy driven air conditioning system for independent temperature and humidity control.

背景技术:Background technique:

前瞻产业研究院《2013-2017年中国智能建筑行业市场前景与投资战略规划分析报告》数据显示,我国的建筑能耗在能源总消耗中所占的比例已经上升到了27.45%。暖通空调能耗又占到建筑总能耗的60%以上,建筑节能减排已成为亟需解决的能源问题。2006年国家颁布了《中华人民共和国可再生能源法》,大力提倡利用可再生能源,增加能源供给,实现经济社会的可持续发展。常见的可再生能源包括太阳能、水能、风能、潮汐能等。鉴于风能、水能等可再生能源的地区差异与不稳定性,在建筑节能中难以有效利用和推广,而太阳能分布广泛,资源丰富,取之不尽,用之不竭。据计算,一年内到达地面的太阳能总量折合成标准煤仍约1.892×1017t,是目前世界主要能源探明储量的一万倍,凭借这些优势,太阳能的开发利用具有极其广阔的前景。在现今能源短缺的时代,各国政府都将太阳能资源利用作为国家可持续发展战略的重要内容。According to the "Analysis Report on Market Prospects and Investment Strategic Planning of China's Intelligent Building Industry from 2013 to 2017" by the Prospective Industry Research Institute, the proportion of building energy consumption in my country's total energy consumption has risen to 27.45%. The energy consumption of HVAC accounts for more than 60% of the total energy consumption of buildings. Building energy conservation and emission reduction has become an energy problem that needs to be solved urgently. In 2006, the state promulgated the "Renewable Energy Law of the People's Republic of China", which vigorously advocates the use of renewable energy, increases energy supply, and achieves sustainable economic and social development. Common renewable energy sources include solar energy, hydro energy, wind energy, tidal energy, etc. In view of the regional differences and instability of renewable energy such as wind energy and water energy, it is difficult to effectively utilize and promote it in building energy conservation, while solar energy is widely distributed and rich in resources, which are inexhaustible and inexhaustible. It is calculated that the total amount of solar energy reaching the ground in one year is still about 1.892×10 17 t equivalent to standard coal, which is 10,000 times the proven reserves of the world’s main energy sources. With these advantages, the development and utilization of solar energy has extremely broad prospects. In today's energy shortage era, governments around the world take the utilization of solar energy resources as an important part of their national sustainable development strategies.

传统的空调系统,让空气通过低于其露点温度的冷表面,即冷凝除湿方式(采用7℃的冷冻水)实现对空气的降温与除湿处理,同时去除建筑的显热负荷与潜热负荷(湿负荷)。降温要求冷源温度低于空气的干球温度,除湿要求冷源温度低于空气的露点温度,占总负荷一半以上的显热负荷本可以采用高温冷源排走,却与除湿一起共用7℃的低温冷源进行处理,造成了能量利用品位上的浪费。通过冷凝除湿方式对空气进行冷却和除湿,其吸收的显热与潜热比只能在一定的范围内变化,而建筑室内环境调节所需要的热湿比却在较大的范围内变化。而且,冷凝除湿方式产生的潮湿表面成为霉菌等生物污染物繁殖的良好场所,严重影响室内空气品质。The traditional air-conditioning system allows the air to pass through the cold surface below its dew point temperature, that is, the condensation and dehumidification method (using chilled water at 7°C) to achieve cooling and dehumidification of the air, while removing the sensible heat load and latent heat load of the building (humidity). load). Cooling requires the temperature of the cold source to be lower than the dry bulb temperature of the air, and dehumidification requires the temperature of the cold source to be lower than the dew point temperature of the air. The sensible heat load, which accounts for more than half of the total load, can be discharged by the high-temperature cold source, but it shares 7°C with the dehumidification. The low-temperature cold source is processed, resulting in a waste of energy utilization grade. When the air is cooled and dehumidified by condensation and dehumidification, the ratio of sensible heat to latent heat absorbed can only change within a certain range, while the heat-to-moisture ratio required for indoor environmental regulation in buildings varies within a larger range. Moreover, the wet surface produced by the condensation dehumidification method becomes a good place for the reproduction of biological pollutants such as mold, which seriously affects the indoor air quality.

清华大学江亿院士提出的温湿度独立控制空调系统,采用除湿的方法调节新风湿负荷,采用制冷的方法降低空气的显热负荷,实现温度和湿度的独立调节,在系统节能和热舒适性控制方面实现了理论突破。温湿度独立控制空调系统,制冷采用高温冷源,可以提高系统能效,降低能源支出,除湿过程能够强化对空气品质的处理,降低室内空气污染。该系统能够克服传统空调系统能耗大、舒适性差、调节性能差的缺点。The temperature and humidity independent control air-conditioning system proposed by Academician Jiang Yi of Tsinghua University adopts the method of dehumidification to adjust the fresh air humidity load, and adopts the method of refrigeration to reduce the sensible heat load of the air, so as to realize the independent adjustment of temperature and humidity, and to control energy saving and thermal comfort in the system. A theoretical breakthrough has been achieved. The temperature and humidity are independently controlled by the air-conditioning system, and the high-temperature cold source is used for refrigeration, which can improve the energy efficiency of the system and reduce energy expenditure. The dehumidification process can strengthen the treatment of air quality and reduce indoor air pollution. The system can overcome the shortcomings of the traditional air-conditioning system, such as high energy consumption, poor comfort and poor adjustment performance.

但是,目前已应用的温湿度独立控制空调系统多采用:蒸汽压缩式制冷方式+冷凝除湿(或者溶液除湿),仍然存在能源消耗大的缺点。本发明突破传统思路,将吸收式制冷系统与溶液除湿系统进行融合,组成温湿度独立控制空调系统,这两个子系统都属于吸收式热力系统,都可以用热能驱动,本发明采用太阳能驱动该空调系统。同时,该空调系统在热利用方面,尽可能的采用了温度梯度利用、热回收等节能形式,提高能源利用效率。However, currently applied temperature and humidity independent control air conditioning systems mostly use: vapor compression refrigeration method + condensation dehumidification (or solution dehumidification), which still has the disadvantage of large energy consumption. The invention breaks through the traditional thinking and integrates the absorption refrigeration system and the solution dehumidification system to form an air conditioning system with independent temperature and humidity control. Both subsystems belong to the absorption thermal system and can be driven by thermal energy. system. At the same time, in terms of heat utilization, the air-conditioning system adopts energy-saving forms such as temperature gradient utilization and heat recovery as much as possible to improve energy utilization efficiency.

申请号201520621166.5的中国专利公开了一种太阳能溶液除湿温湿度独立控制空调系统,该空调系统仅采用太阳能驱动溶液除湿模块,从而达到处理空气湿度的目的,空气温度处理的部分(显热处理)没有采用太阳能驱动,形式与结构简单,不能够形成温度的梯级利用,建筑节能效果不够明显。本发明除了对太阳能的强化利用之外,还对耦合系统采用了温度梯度利用,对用户房间的送风和回风形式进行了设计,强化了热回收利用。The Chinese patent with application number 201520621166.5 discloses an air-conditioning system for independent control of temperature and humidity of solar solution dehumidification. The air-conditioning system only adopts solar-driven solution dehumidification module, so as to achieve the purpose of processing air humidity, and the part of air temperature processing (sensible heat treatment) is not used. Solar powered, simple in form and structure, cannot form a cascade utilization of temperature, and the building energy saving effect is not obvious enough. In addition to the enhanced utilization of solar energy, the invention also adopts the temperature gradient utilization for the coupling system, designs the air supply and return air forms of the user's room, and strengthens the heat recovery and utilization.

Mixing it with outdoor fresh air and sending it to the regenerator can improve the regeneration efficiency of the regenerator. In addition, a solution heat exchanger is arranged in the solution circulation loop of the regenerator and the dehumidifier, which not only reduces the heat required for the regeneration process and the cooling capacity required for the dehumidification process, but also improves the overall efficiency of the solution dehumidification module.
