What is glide and the resulting consequences for the superheat setting

- In the coming decades, old refrigerants will be replaced with newer, more sustainable refrigerants. To reduce both global warming potential (GWP) and ozone depletion potential (ODP), refrigerants are sometimes mixed together to create blends - an example being R407F, which consists of three different refrigerants.
Due to the different boiling and condensation points of the blended refrigerants, some complications and considerations arise. Watch the video for a full explanation of glide and what should be done about it.

Great explaination
Excellent explanation.....thank you
Thanks, Mohanad. 👊
soo great
Thanks for the feedback!
Duper-Video!
Great
Thanks!
Great video....but I'm a little perplexed. R32 at -12C = 4.42 barg.....but R125 at the same 4.42 barg = -6.49 and not -10C 🤔. Also...at 4.42 barg, R134a has a saturation temperature of +18.36 C...and not -8C. I'm assuming that the saturation pressure remains constant (it may have been useful if you had made a reference to saturation pressure) .... I'm sure I've missed something.....please explain ? 🤔 best regards R
Hi Robin. Please refer to our website dedicated to refrigerants - www.danfoss.com/en/about-danfoss/our-businesses/cooling/refrigerants-and-energy-efficiency/danfoss-refrigerant-transition-center/. Hope this is helpful!
Not really an answer to my question.....but thanks anyway ☹
is the input / output of the evaporator reversed on the diagram ???
Hi, Thank you for your comment. The flow shown is from left to right, both in the evaporator and in the log-p, h diagram. Hope this was helpful :-)
@@DanfossClimate thanks🙏
I want to know for calculation, what is the factor at 0.65?
Please check page no 10. in the Retrofit and High Glide

Hope this will help.
Any chance you could remake this video in English?
Hi Chris, the language of the video is English. You are also able to turn on the English subtitles.
@@DanfossClimate I beg to differ. If it were English, he wouldn't pronounce 'dew' in such a way. If you'd like to check the British English pronunciation, you'll see I'm correct.
@@chrisleon7312 Ok troll. You need to learn the difference between language and accent.
how to know at what pressure our regrigerant will work? Do we put the atmosphere pressure of the city we are going to built on it or else?
Determining the right pressure for a refrigerant depends on two things:
1. The system and the internal pressure it is designed for
2. Which refrigerant you are using
