中央空调系统能耗组成要点

来源:http://www.jnslshwx.com 日期:2018-04-26 发布人:admin
中央空调系统的工作过程中,伴随着不断进行的热交换过程。能量转换在系统中的具体过程大致分为如下几个过程:冷却水系统中,冷却水经冷却水泵进入冷冻机,在冷凝器中吸热后被进入冷却塔,经风扇散热降温后经过冷却水泵到空调主机,形成冷却水循环系统。
The process of central air-conditioning system is accompanied by continuous heat exchange process. The process of energy conversion in the system is roughly divided into the following processes: cooling water system, cooling water passes through the cooling water pump into the freezer, and is absorbed into the cooling tower after heat absorption in the condenser. After cooling the fan, the cooling water pump is cooled by the cooling water pump to the main engine of the air conditioner, and the cooling water circulation system is formed.
济南空调安装在另外一个循环系统中,冷冻水经冷冻水泵进入冷冻主机,在蒸发器内降温后送到风机盘管或末端装置,表冷器在空调室内吸热升温后,再由冷冻水泵送到主机蒸发器形成冷冻水循环系统。
The air conditioner in Ji'nan is installed in another circulation system. The frozen water passes through the frozen water pump into the freezer, and then is sent to the fan coil or end device after the evaporator is cooled in the evaporator. The cooling water pump is heated up in the air conditioning room, and then the freezer is sent to the main engine evaporator to form the frozen water circulation system.
从中央空调系统结构图中可以看出中央空调系统的能耗包括冷水系统和冷却水系统中水泵能耗、空调制冷主机能耗、冷却塔泵设备能耗和末端设备能耗。针对中央空调系统的能耗组成,从节能潜力大的部分着重分析设备能效,提高系统能效比。在中央空调系统所有设备中,主机及末端往往对空调系统做功大,这两种设备能耗较之冷水泵、冷却水泵、冷却塔能耗更大。
The energy consumption of the central air conditioning system includes the energy consumption of the water pump in the cold water system and the cooling water system, the energy consumption of the main engine of the cooling tower, the energy consumption of the cooling tower pump equipment and the energy consumption of the terminal equipment. According to the energy consumption of central air conditioning system, the energy efficiency potential and the energy efficiency ratio of the central part of the central air-conditioning system are analyzed. In all the equipment of the central air conditioning system, the main engine and the end often do the work of the air conditioning system, and the energy consumption of these two kinds of equipment is greater than that of the cold water pump, the cooling water pump and the cooling tower.
