Description
技术领域technical field
本实用新型涉及建筑新风技术领域，具体为一种低能耗建筑新风系统。The utility model relates to the technical field of fresh air for buildings, in particular to a fresh air system for buildings with low energy consumption.
背景技术Background technique
目前，随着民用建筑围护结构的逐步改善，门窗气密性和隔热性能变得越来越好，从而大大降低了建筑空调系统的冷热负荷，有利于建筑节能。但另一方面，如果室内空气品质得不到良好的处理与置换，往往会引发较为严重的二次污染问题。近年来建筑新风系统逐渐引起人们的高度重视。At present, with the gradual improvement of the envelope structure of civil buildings, the airtightness and heat insulation performance of doors and windows has become better and better, thus greatly reducing the cooling and heating load of the building's air conditioning system, which is conducive to building energy saving. But on the other hand, if the indoor air quality is not treated and replaced well, it will often cause serious secondary pollution problems. In recent years, the building fresh air system has gradually attracted people's attention.
就公共建筑而言，最为典型的建筑新风系统机组一般直接处理来自室外的新风，不承担室内热湿负荷，往往需要依赖中央空调系统运行提供的冷却水源，并在此基础上对新风进行冷却、加热、加湿处理，以满足室内建筑的空气品质和温湿度要求。根据统计，上述新风处理能耗约占空调系统总能耗的20-30％。在当前建筑节能减排的持续压力下，如何进一步降低建筑新风系统能耗已经成为一个关键问题。As far as public buildings are concerned, the most typical building fresh air system unit generally directly handles the fresh air from the outside and does not bear the indoor heat and humidity load. It often needs to rely on the cooling water source provided by the operation of the central air conditioning system, and on this basis to cool the fresh air. Heating and humidification treatment to meet the air quality and temperature and humidity requirements of indoor buildings. According to statistics, the above-mentioned fresh air processing energy consumption accounts for about 20-30% of the total energy consumption of the air conditioning system. Under the continuous pressure of building energy saving and emission reduction, how to further reduce the energy consumption of building fresh air system has become a key issue.
土壤-空气换热器可以利用浅层土壤对室外新风进行预冷或预热，然后送入室内各个房间，这成为降低建筑新风能耗的一种有效途径，进而发展出基于土壤-空气换热器的建筑新风系统(简称土壤-空气换热建筑新风系统)。例如，实用新型专利“一种基于土壤-空气换热的建筑新风系统”(CN202598741U)和“一种土壤-空气换热系统”(CN204612043U)均属于此类建筑新风系统。但是，在实践应用中发现，此类新风系统仍然存在的一定的技术局限性，例如风机主要依靠常规市电驱动，长时间运行条件下能耗较高，不利于进一步降低系统能耗；室内送风主要按照单位建筑面积或人均新风量进行计算，很容易造成风量偏大的问题，进而使得与之匹配的地下土壤-空气换热管群数量变大，引起系统建设和运行成本增大，很大程度上降低了系统的适用性。The soil-air heat exchanger can use the shallow soil to pre-cool or preheat the outdoor fresh air, and then send it to each room in the room. This becomes an effective way to reduce the energy consumption of building fresh air, and then develops a soil-air heat exchange based The building fresh air system of the device (referred to as the soil-air heat exchange building fresh air system). For example, the utility model patents "a building fresh air system based on soil-air heat exchange" (CN202598741U) and "a soil-air heat exchange system" (CN204612043U) both belong to this type of building fresh air system. However, in practical application, it is found that this type of fresh air system still has certain technical limitations. For example, the fans are mainly driven by conventional commercial power, and the energy consumption is high under long-term running conditions, which is not conducive to further reducing system energy consumption; The wind is mainly calculated according to the unit building area or per capita fresh air volume, which can easily cause the problem of excessively large air volume, which in turn will increase the number of matching underground soil-air heat exchange tube groups, resulting in increased system construction and operating costs, which is very It greatly reduces the applicability of the system.
