You are such great explainer. Having knowledge is not good but transfering it efficiently is an art and you are the Artist sir thank you so much for your efforts. Love the way you explain. One by one im watching all your vdos.
Ty. I know it is not related request. But since topic is metering device and I remember watching your heat pump early on in class great explanation. Would you be willing to put videos on wiring heat pump with old mechanical devices rather than board such as defrost board. I come across lots of new tech because of modern technology they don't understand if they have to wire it in old school way just to understand the sequence of operation. Thanks again for your time and help heat community.
Hello Ty, I have a friend live in the Middle East and he asking about the ductless mini split utilize with an orifice tube how can check the refrigerant? Thanks.🌷
Most of the ductless units have the metering device outside. They have very specific charging instructions by weight and length of Refrigerant line. While some do use a capillary tube they usually have an electronic expansion valve outside. Because it's outside you can't do subcooling. Most are variable speed so you can't really do superheat either. Craig with ac service tech and Bryan Orr HVAC school both have some great ductless units.
@@love2hvac Thank you so much Ty, the metering device (orifice tube) inside in the evaporator and it’s not EEV, I checked Criage video’s it’s different in metering device it’s EEV.
Thanks for the video, I have a question, is the position of the TEV bulb correct as shown? against the direction of the refrigerant? Or is it indifferent how it is placed? thank you
1st Always follow the manufactures specifications. When the bulb is in the vertical position most manufactures want the cap tube up on too so only vapor is leaving the bulb. When horizontal it's best practice to keep the cap tube high so vapor only leaves. As far as direction of refrigerant flow, it has no effect on the bulb itself as it's just temperature and pressure. However with flow can play a factor in relation to the equalization tube. When
