Description
技术领域 technical field
本发明主要涉及暖通空调领域,尤其涉及一种基于半闭式空间的空调冷却塔系统。 The invention mainly relates to the field of heating, ventilating and air-conditioning, in particular to an air-conditioning cooling tower system based on a semi-closed space.
背景技术 Background technique
冷却塔是暖通空调系统的重要组成部分,其作用是将携带余热的循环水在塔内与空气进行热交换,把水的热量传输给空气并散入大气,对循环水进行降温。冷却塔运行性能的好坏直接影响着空调系统制冷制热的效果。 The cooling tower is an important part of the HVAC system. Its function is to exchange heat between the circulating water carrying waste heat and the air in the tower, transfer the heat of the water to the air and disperse it into the atmosphere, and cool down the circulating water. The operating performance of the cooling tower directly affects the cooling and heating effect of the air conditioning system.
影响冷却塔运行性能的因素包括空气湿球温度、空气流量、水量、冷却塔的布置等,其中冷却塔的布置位置与方式是影响冷却塔运行性能好坏非常关键的因素之一。冷却塔一旦布置不合理,将导致湿热空气返混,从而严重影响着冷却塔运行性能。所以,为了降低冷却塔湿热空气返混,冷却塔通常放置通风良好的室外,如楼顶或地面,并要求排风口、进风口通畅。 Factors that affect the operation performance of cooling towers include air wet bulb temperature, air flow, water volume, cooling tower layout, etc. Among them, the location and method of cooling tower layout are one of the key factors that affect the performance of cooling towers. Once the cooling tower is unreasonably arranged, it will lead to back mixing of hot and humid air, which will seriously affect the operating performance of the cooling tower. Therefore, in order to reduce the back-mixing of hot and humid air in cooling towers, cooling towers are usually placed outdoors with good ventilation, such as the roof or the ground, and the air outlets and air inlets are required to be unobstructed.
然而,冷却塔放置于楼顶或地面,将产生很大噪音同时影响建筑物整体美观。近年来,人们对城市环境日益关注,冷却塔越来越多地被置于专门的靠外墙的制冷机房或建筑转换层等相对较封闭的空间内;另外随着单体建筑物建筑面积的增大,所需冷却塔的数量越来越多。当大量的冷却塔被布置在一个半闭式空间内,就会造成以下几个问题:1、空气与循环水进行热量交换产生的湿热空气不能很好地排出半闭式空间,湿热空气返混率较高;2、冷却塔群运行相互干扰、冷却塔进排风短路、排风不畅;3、靠近半闭式空间进风口的冷却塔进风量过大,而居于半闭式空间中部的冷却塔进风量过小,冷却塔风机选型难以确定,冷却塔运行效率低。这些问题造成冷却塔不能在额定工况下高效运行,从而直接影响着整个空调系统制冷制热的效果。 However, if the cooling tower is placed on the roof or on the ground, it will generate a lot of noise and affect the overall appearance of the building. In recent years, people have paid more and more attention to the urban environment, and more and more cooling towers are placed in relatively closed spaces such as special refrigeration rooms near the outer wall or building transfer floors; in addition, with the increase in the construction area of single buildings Increasingly, the number of cooling towers required is increasing. When a large number of cooling towers are arranged in a semi-closed space, the following problems will be caused: 1. The hot and humid air generated by the heat exchange between air and circulating water cannot be discharged from the semi-closed space well, and the back-mixing rate of hot and humid air 2. The operation of the cooling tower group interferes with each other, the air intake and exhaust of the cooling tower are short-circuited, and the exhaust air is not smooth; 3. The air intake of the cooling tower near the air inlet of the semi-closed space is too large, and the cooling tower located in the middle of the semi-closed space The air intake volume of the tower is too small, it is difficult to determine the type of cooling tower fan, and the operating efficiency of the cooling tower is low. These problems make the cooling tower unable to operate efficiently under rated working conditions, which directly affects the cooling and heating effect of the entire air conditioning system.
目前,室外冷却塔布置单纯依靠工程经验来进行,并取得很好的冷却效果。但对于半闭式空间内冷却塔群的布置如果单纯依靠工程经验来进行布置以及采用室外冷却塔群布置设计方法,将会使部分冷却塔运行性能恶化,从而影响整个空调性能运行效果,因此必须寻找另外一种半闭式空间内冷却塔群布置方案以及提高冷却塔群运行性能的优化方案。 At present, the layout of outdoor cooling towers is based solely on engineering experience, and a good cooling effect has been achieved. However, if the layout of the cooling tower group in the semi-closed space is based solely on engineering experience and the layout design method of the outdoor cooling tower group is used, the operating performance of some cooling towers will deteriorate, thereby affecting the performance of the entire air conditioner. Therefore, it is necessary Find another arrangement scheme of cooling towers in a semi-closed space and an optimization scheme to improve the operation performance of cooling towers.
