摘  要:结合目前全社会所面对的能源紧张问题和响应节能建筑的号召,本文提出了一种新型的空气处理机组——全热交换能量回收型全新风机组。该新风机组研发的目的在于回收空调排风的余热量,尽可能地减少空调在处理新风上的能源消耗;同时达到人们对空调室内空气质量提出的高标准、高要求。

  本文详细阐述了全热交换能量回收型全新风机组的工作原理,分析了该新风机组具有诸如通风换气、能量回收、过滤净化等多方面的特点;通过两篇文献的部分内容,分析出前级全热交换能量回收的最佳点是寒冷气候地区的冬季,而华南气候地区以广州为例,强制冷区所占的区域越大,新风全热回收的节能效果越显著。

  在给定的新风参数和新风量条件的基础上,查阅多种参考文献,进行了热力计算,选出了合适的压缩机型号后,才开始了对冷凝器、蒸发器进行设计和校核的相关工作;待基本设计工作完成后,开始了其他的相关附件设备如:节流装置、油分离器、气液分离器等的选型工作;最后,笔者通过仅改变室外新风的状态来分析该新风机组对变进风条件的适应性,得出了该新风机组适宜的运行范围,发现其有一定的局限性;提出了机组在布置、运行、控制等方面的要求。

关键词:全热回收、新风机组、设计、控制

 

Abstract:Combining society's energy crisis and response of energy-saving building's call, this paper puts forward a new kind of air handling units —— the entire heat recovery fresh air handling unit. This research aims to fresh air unit of recycling air conditioning wind over heat, as far as possible to reduce air conditioning in dealing with the fresh air on energy consumption; and satisfy people in that claim air conditioning indoor air quality is high standard, high demand.

  This paper expounds the recyclable heat energy smoke-expelling unit work principle, analyzes the fresh air unit has such as ventilated take a breath, energy recovery, filtered and so on various characteristics; Through two papers, analysis of the part of the preamp all the best point heat energy recovery is cold climates of winter, and climate region of south in Guangzhou as an example, the refrigeration area accounts for the strong regional, the greater the heat recovery of fresh energy saving effect all the more notable.

  In a given fresh air parameters and the basis of the conditions of the fresh air volume, to refer to different references, the thermodynamic calculation, and choose the right compressor types, to the design of condenser, evaporator and checking of relevant work; while basic design work is completed, start other relevant accessory equipment such as: the throttle device, oil separator, such as selection of gas-liquid separator; Finally, the author of the state only change outdoor air to analyze this fresh air unit of the variable into wind conditions, that the adaptability of fresh air unit appropriate operation scope, found that it had some limitations; Puts forward unit in layout, operation and control requirements.

Keyword: heat recovery, fresh air handling unit, design and control
