The function of Suction ccumulatorwith heat exchangeristo put the pipes for high pressure high temperature refrigerantand lowpressure lowtemperature refrigerant to one vessel to exchange high and low temperature,tocool orwarming refrigerant.After the heat exchange, abetter performance of the whole systemand cooling effect achieved.

Inairconditioningrefrigeration,therefrigerant pipelineshave high pressure and low pressure lines,the high pressurerefrigerant with high temperature needs cooled,and the low pressure from evaporator needed to be separated to liquidand gasrefrigerant,the liquid refrigerant needsome timeandtemperaturetobeevaporated togasand then enter tocompressor.Itavoids liquid slugging to protect compressor.

在空调制冷系统中，制冷剂管路可以分为高压和低压两个部分，高压制冷剂的温度较高需要冷却器来冷却，而经过蒸发器的低压制冷剂，需要气液分离器来分离气态和液态，而液态制冷剂则需要时间和温度升高蒸发，成为气态后才能进入压缩机，避免液压缩。热交换气液分离器的功能就是把高压高温需要冷却的制冷剂与低压低温需要温度来蒸发的制冷剂两个管路集中通过一个容器传递高低温，使需要冷却的制冷剂得到低温，需要加热的制冷剂得到加温，在经过这一冷热交换的作用后，大大提高了制冷效率，达到更好的制冷效果。适用于蒸发温度低于 1 5 ^ { \circ } C的制冷装置中。强大的分离能力和冷热交换能力，可避免未过热的湿蒸汽进入压缩机；制冷剂进入热力膨胀阀前使其过冷(避免出现闪发气体)，可提高制冷效率。

Applications

Compressors are extremely susceptible to damage fromliquid refrigerant.Excessive liquid refrigerant return may causenotonly oil dilution but complete lossof the compressor oil chargewhich resultsin equipmentdamagedueto lackof properlubrication. The primary functionofaSuction LineAccumulator isto preventa sudden surge of liquid refrigerant, or oil,from returning down the suction line and into acompressor.The suction line accumulator isa temporaryreservoirfor liquid refrigerantandoil.

To avoid liquid slugging,the refrigerant must be converted to gas before returning to compressor, thusthe refrigerantmustbe separated to liquid and gasbeforeenteringcompressor,only gasallowed toentertocompressor.The liquid refrigerantevaporates slowly in the accumulator and enters to compressor after converting to gas.In order to return remaining oil tocompressor,there isan oil return orifice inthe bottom of U tube of the accumulator.The remaining oil in system will flow toaccumulatorand return to compressorwith gasrefrigerant.

1、警告：在安装单向阀前系统必须抽真空，管路减压；
2、确保流量箭头方向与需要的流动方向一致；
3、适当清洁单向阀，准备接头，如有需要则使用助焊剂；
4、焊接时用湿布包裹阀体以防止内部零件过热；
5、焊接时使火焰远离阀体，防止阀体过热；
6、接头自然冷却，不可冷浸。

Installation Note

Before fitting the valve to the pipe,itisadvisable to make sure therefrigerationsystemis clean.
1.Wheninstalling solenoidvalves,must ensure thearrowdirection in the valve bodyissame flow direction.lf thesolenoidvalveinstalledaheadofathermostaticexpansionvalve,normally,install it close to that expansion valve.It can avoid liquid slugging when the solenoid valve opens.
2.Make sure the pipes around the valve are installed correctly.
3.Allthe valves can be fitted in whatever position except with the coil pointing downwards.
4.If proper heat proof adopted when Brazing/welding,dismantling is not required normally. Donotspatter the weld bead to the armature tube.
5.Remove the valve body to protect O-ringsand gaskets against heat when welding the valve to the pipe.
6.Ensure the solenoid valves in the system are open when testing pressure,eitherapply voltage to the coils or open the valves manually(a manualoperation spindleis present).Mustscrew the spindle back before starting up,or the valvewill not close.
7.Use counterforce when tightening the solenoid valve to pipes,i.e.using two spanners on the same side of the valve.

Coilinstallation

1.Before mountingavalve to the electrical system,ensure the values markedon the coilcorrespond to the line voltage and frequency.
2.When assembling the coil,simply to press down it over the armature tube until heard a click. It means the coil has been assembled correctly. - Be sure to fitan O-ring between valve body and coil,and ensure theO-ringis smooth without damage and surface clean. -Ensure to change the O-ringat service.
3.Inserta screwdriver between valve body and coil can easily remove the coil.And the screwdriver alsocanbeusedasalevertoloosenthecoil.
4.Notice thecable entries,protectthe terminal boxaway from water,and the cable mustbe led out via a drip loop.
5.Using round cablealways,asitis theonly type of cable thatcan besealed effectively,andbe sure cableentryretainstheentirecablecircumference.
6.Check the colorof leads in the cable,leads of one color are eitherphase or neutral.
7.Use two screwdrivers or other hand toolswhen removinga coil.

Coilchoose

Ensure thevalveand coilmatch each other.
Fitting wrong coilwill result in coil burnt out ora lowe MOPD.
·NC (normally closed) solenoid valve:Usedforthe system that the valve must keep closed in the mostoperatingtime.
·NO (normally open)solenoid valve:Used for the system thatthe valve must keep open in the most operating time. Remember never replace an NO solenoid valve with an NC solenoid valve-orreplace an NC solenoidvalvewithan NO solenoid valve.

1、安装线圈时，只需在枢管上按下线圈，直至听到喀嗒一声。这表示已经正确安装了线圈。

注意：记住在阀体和线圈间安装一个O型环。在维修时必须更换O型环。

2、在阀体和线圈之间插入一把螺丝刀便可拆下线圈。然后将螺丝刀用作杠杆来松开线圈。

3、请注意电缆入口。一定要防止水进入接线盒。电缆必须通过滴水圈引出。

4、整个电缆圆周必须在电缆入口之内。因此，应始终使用圆形电缆（这是唯一一类可以有效密封的电缆）。

5、了解电缆中导线的颜色。每种颜色的导线不是相线便是中性线。

6、在拆除线圈时可能会用到手工工具，例如两把螺丝刀。对于阀门在大多数工作时间内必须保持闭合（未通电）的系统，应使用NC（常闭）电磁阀。对于阀门在大多数工作时间内必须保持开启（未通电）的系统，应使用NO（常开）电磁阀。不能使用NC（常闭）电磁阀来替换NO（常开）电磁阀，反之亦然。
