中央空调系统的特点介绍

来源: 日期:2018-10-05 发布人:admin
中央空调由空调主机提供冷源或热源,并通过水泵与专用管道,将冷量或热量送至空调末端设备,在输送过程中通过调节水泵转速、数量或者管道阀门,来控制流量的大小。中央空调应用场合较为广泛,根据不同特性,分很多种类,并具有各自特点:
The central air-conditioning is provided with cold or heat sources by the main air-conditioning unit, and the cooling or heat is sent to the terminal equipment of the air-conditioning through the water pump and special pipeline. The flow rate is controlled by adjusting the speed, quantity of the water-saving pump or the pipeline valve during the transportation process. Central air conditioning is widely used in many fields. According to different characteristics, it can be divided into many types and has its own characteristics.
(1)按照冷(热)量传递形式分类
(1) classification according to the transfer form of cold (heat) quantity.
分为水冷(热)和风冷(热)两种主要类型。简而言之,水冷型是由空调主机集中产生热水或冷水,并通过管道送到各风机盘管末端,通过末端风机,产生热风或冷风,达到升温或降温效果。风冷(热)型是以冷(热)风的形式,通过管道送到空调各区域,但是这样的方式能量损失也较大。前者设备投入高,点位的控制相对较为方便;后者设备成本低,但是风道体积较大,点位不易控制。
It can be divided into two main types: water cooling (heat) and air cooling (heat). In short, the water-cooled type is by the air-conditioning main engine centralized production of hot or cold water, and through the pipe to the end of each fan coil, through the end of the fan, produce hot or cold air, to achieve heating or cooling effect. Air-cooled (hot) type is in the form of cold (hot) wind, through the pipe to the air-conditioning area, but this way of energy loss is also greater. The former has high equipment input and relatively convenient point control, while the latter has low equipment cost, but the volume of the duct is large and the point is difficult to control.(2)按照能量提供形式分类
(2) categorization according to the form of energy supply.
主要分为单冷型和冷暖型。单冷型是指只能供给冷量,用以降低空间温度单一功能的中央空调。冷暖型是指,同时具备供热和供冷能力的复合功能的中央空调。这两类主要是使用地域的区别,单冷型多应用于南方城市,冷暖型以中部城市居多。
It is mainly divided into single cooling type and cold warm type. The single cooling type refers to the central air-conditioning which can only provide cooling capacity to reduce the single function of space temperature. The cold and warm type refers to the central air-conditioning with the function of heating and cooling. These two types are mainly the use of geographical differences, single-cold type is mostly used in southern cities, cold and warm type in the central cities.
(3)按照使用场合分类
(3) classification according to the occasion of use
分为大型商用、小型家用两种类型。两者在工作原理上大致相同,主要区别在于各自的工作场合。大型商用中央空调设计更为复杂,机组要求更为苛刻,设施设备成本较高;小型家用类型,相较而言,结构与施工更为简单,成本低廉。
It can be divided into two types: large commercial and small household. The two are basically the same in terms of working principles, and the main difference lies in their working situations. Large commercial central air conditioning design is more complex, unit requirements are more stringent, the cost of facilities and equipment is higher; small household type, compared with the structure and construction is simpler, low cost.
