293VALVES - CarelWhy use an Electronic Expansion Valve?Limitations of Mechanical Valves:• Narrow Capacity• Slow movement / reaction • Refrigerant specific • R equires periodical maintenance as the behaviour is unsurveyed.• Requires a solenoid valve on the the liquid line • R equires specific liquid refrigerant temperature / pressure to operateBenefits of an Electronic Expansion Valve:• I ncomparably more precise control, bettersuperheat control = better performance = higher efficiency• Wide capacity range• Quickly adapts to system demand• Non refrigerant specific (Excluding R717)• T he ideal solution when used with variable speed compressors • P ermits floating condensing temperature management • Energy savingWhere is the energy saved?• The energy is primarily saved at the compressor.• H igher efficiency components ensure the system is working at it’s optimal design. This results in longer compressor off periods, or longer periods with the compressor at minimum capacity • E nergy is saved by reducing the operating head pressure, as the high head pressure that would be required for mechanical valves is no longer needed. Operating at Lower head pressures = improved Co-efficient Of Performance of the compressorWhy use a Carel Electronic Expansion Valve?• H igh quality construction = higher efficiency and reliability • T ight shut off guaranteed by unique T eflon seal, seat and blocking spring • Removable stator• Internal gearless, stainless steel mechanism • Bi directional flow capability • E qual percentage flow characteristic ensures accurate control at all valve opening positions294mf .au sales@mf .auCarel - VALVES With capacity ranging from 0.1 kW to2000 kW, there would be a Valve suitable to your application.Valve SizingDue to the vast range of applications and variables to consider when selecting an Expansion valve, it isHIGHL Y suggested the valve is sized correctly by a Refrigeration Engineer.Carel have developed an online sizing tool.

电子膨胀阀工作原理及其控制方法探讨【摘要】随着制冷设备的发展，越来越多的高效节能空调产品面世。

而作为制冷系统的四大部件之一，节流装置在制冷系统中起着非常重要的作用，通过选择应用合适的节流机构与制冷系统匹配是整个制冷设备降低能耗的重要一环。

本文将对节流装置其中之一电子膨胀阀的基本结构、工作原理及控制方法进行分析。

【关键词】电子膨胀阀;制冷;节能;节流装置;控制0.引言电子膨胀阀作为一种新型的制冷系统控制部件，突破了传统节流机构的概念，它是制冷系统智能化系统化的重要环节和手段。

空调设备在电子膨胀阀的应用方面，突破了以前在机组设计过程中存在的某种系统屈从热力膨胀阀的观念，进入膨胀阀为系统优化服务的新阶段，其应用使空调设备达到更高的控制精度及工艺要求，对于制冷行业的发展起着重要的作用。

1.传统的节流装置介绍传统的节流装置包括手动节流阀、孔板、热力膨胀阀等。

手动节流阀越来越少见，几乎已经被淘汰。

而孔板只在某一些设备上使用，例如满液式水冷冷水机等。

热力膨胀阀广泛应用于中央空调设备上。

它既可控制蒸发器供液量，又可节流饱和液态制冷剂。

根据热力膨胀阀结构上的不同，分为内平衡式和外平衡式两种。

外平衡式热力膨胀阀在大量使用，其工作原理是建立在感温包内工质压力、蒸发器出口压力及弹簧力平衡的基础上。

但由于热力膨胀阀的感温包具有热容量、传压毛细管的压力传递以及机械动作等系列环节的时间滞后，故，其调节响应速度、精度等远比不上电子膨胀阀。

2.电子膨胀阀介绍2.1结构单从结构上看，电子膨胀阀主要由阀体、阀针、线圈组成。

而从控制实现的角度来看，电子膨胀阀由控制器、执行器和传感器 3 部分构成，通常所说的电子膨胀阀大多仅指执行器，即可控驱动装置和阀体，实际上仅有这一部分是无法完成控制功能的。

电子膨胀阀控制器的核心硬件为单片机，如控制器同时要完成压缩机及风机的变频等控制功能，一般采用多机级连的形式。

电子膨胀阀的传感器通常采用热电偶或热电阻。
