摘 要 户式中央空调是由一台主机通过风道过风或冷热水管接多个末端的方式来控制不同的房间以达到室内空气调节目的的空调。采用风管送风方式，用一台主机即可控制多个不同房间并且可引入新风，有效改善室内 空气的质量，预防空调病的发生。中央空调Abstract Household central air conditioning is by a host had cold wind or by air hose end up to several different control room in order to achieve the purpose of indoor air conditioning. By the way, with a duct host can control and introducing several different room, effectively improve the indoor air quality, the air KongDiaoBing prevention. This design according to the engineering survey first calculated that the cooling load of each room and the cooling load of the direct evaporation, refrigerant heat pump units. More than yituo After the system is determined according to the cooling load of each room and cooling load of indoor and determine the type, air-conditioners, cold media because type water pipe parameters determined by calculation, and has condensed water pipe. At present, with Chinas economic growth, gradually improved increasingly, people living conditions for the comfort of living environment, the demand for household central air conditioning for central air conditioning energy-saving, comfortable, healthy more attention. Therefore, an energy-saving design, comfortable and healthy central air conditioning project is very practical significance.Key words: Household central air-conditioning Load calculation Refrigerants More than one unit delay 目 录 前言 1 1 绪论 2 1.1 户式中央空调研究背景及意义 2 1.2户式中央空调比传统空调更具优势 2 1.3 我国户式中央空调发展 4 1.4 户式中央空调的特征及优势 6 1.5 户式中央空调系统分类及特点 9 1.5.1 两种常见的户式中央空调系统 9 1.5.2中央空调系统分类 10 2 工程概况 12 2.1 工程概况 12 2.2 设计依据 12 2.2.1 新乡市室外空调设计参数 12 2.2.2 室内空调主要设计参数 13 3 负荷计算 15 3.1 冷负荷计算 15 3.1.1 外墙和屋面瞬变传热引起的冷负荷 15 3.1.2内围护结构冷负荷 16 3.1.3外玻璃窗瞬变传热引起的冷负荷 16 3.1.4透过玻璃窗的日射得热引起的冷负荷 17 3.1.5照明散热形成的冷负荷 17 3.1.6人体散热形成的冷负荷 18 3.1.7设备散热形成的冷负荷 18 3.1.8渗透空气散热形成的冷负荷 19 3.1.9食物散热形成的冷负荷 20 3.1.10散湿量与潜热形成的冷负荷 20 3.3 计算结果 21 4 方案确定 23 4.1 空调系统的分类 23 4.2 几种常用户式中央空调机组的适用范围 25 5 空调设备的选择计算 29 5.1 多联机空调系统连接方式的确定 29 5.2 室内机和室外机的选择 29 5.3设备布置和管道设计 31 5
