EVD4电子膨胀阀驱动器

.EK312.安装使用手册-----2016.08.251 概述EK312A是得麦科技开发的1款电子膨胀阀控制器，采用过热度控制膨胀阀开度。

驱动器采用恒流驱动。

可控制ALCO、DANFOSS、SPORLAN、Carel等各种恒流驱动的电子膨胀阀。

EK312A既可与得麦科技的螺杆机控制器联机使用，也可单独使用（与其他厂家控制器组成控制系统）。

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. It isfreely accessibly but will require a login registration.Go to: /group/exv-sistema/home The virtual sizing console is called ‘Exv Lab’The Application295VALVES- CarelAccessories for EV Series296mf .au sales@mf .auCarel - VALVES EVD Evolution DriversAccessories for EVD DriversEVD Evolution KitsmponentsT o use an electronic valve, the valve will require a valve driver. The Carel range is ever expanding, the primary control to manage an Electronic valve is the EVD Evolution Driver.Other controllers include Ultracella and MPXPRO.Features of the EVD EVO Driver• Superheat management with auxiliary high pressure, low pressure and low superheat protection • Simple start up with just 4 parameters (Refrigerant, application, valve type and sensors)• Ultracap back up integration • Twin version option• Adaptive control algorithms • Digital Scroll suitable• Visual help visible on displayEVD drivers require a pressure transducer and cable, and a strap-on NTC sensorThe kits include a driver, ratiometric pressuretransducer and cable, valve cable and temperature sensor. The display is to be purchased separately.297VALVES - CarelDisplay ModePlease NotePlease read these instructions in conjunction with the parameter list and the installationmanual. It is recommended that the controllers be programmed before connecting or activating the plant to be controlled.An automatic setup procedure appears on the EVD Evo display at startup. The 4 main parameters need to be configured and confirmed to start the driver operation.Installation manual:+0302205EN EVD Evolution+0302206EN EVD Evolution TwinT echnical leaflets:+050004150 EVD Evolution and graphic display +050004155 USB-tLan converter for EVD Evo+050004165 Battery charge and battery for EVD Evo +050004170 EVD Evolution Twin and graphic displayLiterature AvailableMeaning of the LEDsService Parameters (A)Manufacturer Parameters (C)A) PRESS Esc one or more times to switch to the standarvd display PRESS ARROW 'UP' or 'DOWN' to display a graph, the wiring diagram and the main valuesPRESS 'ESC' to exit the display modeA) PRESS Esc one or more times to switch to the standard display B) PRESS 'Prg' to display the password screenC) PRESS 'ENTER' and enter the password '22' then PRESS 'ENTER'D) PRESS ARROW 'UP' or 'DOWN' until reaching the parameter to be modifiedE) PRESS 'ENTER' to access the value.
