文档介绍：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。本设计先根据工程概况计算各个房间的冷负荷和总的冷负荷，选用制冷剂直接蒸发一拖多热泵机组。确定系统后再根据各个房间冷负荷和总冷负荷确定室内机和室外机的型号，由于型号固定，冷媒水管道参数便已确定，只需计算冷凝水管道即可。
目前，随着我国经济的逐步增长，居住条件日益改善，人们对生活环境的舒适性的要求越来越高，对家用中央空调的需求越来越大，对中央空调节能、舒适、健康更加关注。
因此，设计一项节能、舒适、健康的中央空调工程是很实际意义的。

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 China's 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
