风光互补发电的无需水箱蓄冷的蒸发冷却空调系统Evaporative cooling air conditioning system without water tank storage for wind and solar hybrid power generation

技术领域technical field

本发明属于空调设备技术领域,具体涉及一种包括蒸发冷却冷风/冷水机组、风光互补发电系统、内嵌相变蓄冷材料的蒸发冷却盘管、水幕墙和室内末端集成的蒸发冷却空调系统。The invention belongs to the technical field of air-conditioning equipment, and specifically relates to an evaporative cooling air-conditioning system including an evaporative cooling cold air/chiller unit, a wind-solar hybrid power generation system, an evaporative cooling coil embedded with a phase-change cold storage material, a water curtain wall, and an integrated indoor terminal.

背景技术Background technique

近几年,我国建筑能耗占据总能耗比例有所上升,由于空调大部分采用传统的机械制冷,其系统运行的四大部件,需要消耗大量的电能,造成城市夏季出现“拉闸限电”等现象,所以空调的节能已经迫在眉睫。蒸发冷却空调技术,利用天然能源“干空气”能,使用空气干球温度和露点温度之差作为驱动势,来降低空气和水的温度。蒸发冷却冷风/冷水机组能够同时产出冷风和冷水,既满足了室内新风的需求,同时也为室内末端提供了高温冷水,可实现水-空气系统,减少室内过多风管的布置。常规的水蓄冷空调是利用电网的峰谷电价差,夜间利用冷水机组制取冷水在水池内蓄冷,白天水池释放冷量,保证在负荷峰值期间机组的正常运行,它具有投资小、运行可靠、制冷效果好,经济效益高等特点。然而,它需要占用一定的地方建造蓄水池,势必占用一定的空间。当今,相变蓄冷技术发展快速,相变材料已经可以实现吸收一定高温冷水的冷量,将它储存一定时间,在需要时候释放冷量。现代化的建筑多采用玻璃幕墙,外表美观,但通过幕墙不仅能够吸收过多的太阳辐射能,同时也增加了室外产生炫光的问题。In recent years, the proportion of my country's building energy consumption to the total energy consumption has increased. Since most of the air conditioners use traditional mechanical refrigeration, the four major components of the system need to consume a lot of electricity, resulting in "power cuts" in summer in cities. " and other phenomena, so the energy saving of air conditioners is imminent. Evaporative cooling air-conditioning technology uses natural energy "dry air" energy, and uses the difference between air dry bulb temperature and dew point temperature as the driving force to reduce the temperature of air and water. The evaporative cooling cold air/chiller unit can produce cold air and cold water at the same time, which not only meets the needs of indoor fresh air, but also provides high-temperature cold water for the indoor end, which can realize the water-air system and reduce the layout of excessive indoor air ducts. Conventional water-cooled storage air conditioners make use of the peak-valley electricity price difference of the power grid. At night, chillers are used to produce cold water to store cold in the pool. During the day, the pool releases cooling capacity to ensure the normal operation of the unit during the peak load period. It has the advantages of small investment, reliable operation, Good refrigeration effect and high economic benefits. However, it needs to occupy a certain place to build a reservoir, which will inevitably take a certain space. Today, phase change cold storage technology is developing rapidly, and phase change materials can already absorb a certain amount of cold water at high temperature, store it for a certain period of time, and release the cold amount when needed. Modern buildings mostly use glass curtain walls, which are beautiful in appearance, but the curtain walls can not only absorb too much solar radiation energy, but also increase the problem of glare outside.

蓄冷材料28开始释放冷量,将制取的高温冷水通入到室内的末端,吸收室内余热,再通入水幕墙E中的布水管22中,高温冷水均匀地顺着幕墙的外墙流下,在外墙形成一层水幕,能够减少太阳能辐射能向室内的传递,同时也降低了室外眩光的产生,流下的水落在了下方设置的水箱,在回到机组中。The cold storage material 28 begins to release cold energy, and the high-temperature cold water produced is passed into the end of the room to absorb the residual heat in the room, and then passed into the water distribution pipe 22 in the water curtain wall E, and the high-temperature cold water flows down evenly along the outer wall of the curtain wall. The wall forms a layer of water curtain, which can reduce the transmission of solar radiation energy to the interior, and also reduce the generation of outdoor glare. The water that flows down falls into the water tank set below and returns to the unit.

白天蒸发冷却冷风/冷水机组可以开启,已补充释冷量的不足。During the day, the evaporative cooling air/chiller unit can be turned on to make up for the lack of cooling capacity.

本发明的蒸发冷却空调系统,利用自然的风能和光能发电,提供蒸发冷却冷空调系统运行所需要的能耗。蒸发冷却冷风/冷水机组利用峰谷电价差,在夜晚制取冷风和冷水,由于设置的内嵌相变蓄冷材料的蒸发冷却盘管,实现了冷水制取和蓄冷一体化,可以直接将蒸发冷却制取的冷水,储存起来,白天释放冷量,为室内末端和水幕墙的布水管提供高温冷水;制取的冷风,夜晚可以向室内通风,降低白天室内的负荷。The evaporative cooling air-conditioning system of the present invention utilizes natural wind energy and light energy to generate electricity, and provides the energy consumption required for the operation of the evaporative cooling air-conditioning system. The evaporative cooling cold air/chiller unit uses the difference in peak and valley electricity prices to produce cold air and cold water at night. Due to the evaporative cooling coil embedded with phase change cold storage materials, the integration of cold water production and cold storage is realized, and the evaporative cooling can be directly The cold water produced is stored and released during the day to provide high-temperature cold water for the water distribution pipes at the end of the room and the water curtain wall; the cold air produced can be ventilated to the room at night, reducing the load on the room during the day.
