VRF Systems Explained - Variable refrigerant flow basics HVAC

Published 2022-04-23
VRF System basics, understand the different types of VRF VRV systems and the basics of how they work in the HVAC industry.
🎁 See the ETS 5M in 3D ➡️ bit.ly/3nc5s4m

The ETS 5M ensures low acoustic level and offers full performance bi-flow capability-enabling quiet, precise performance for both cooling and heating.

In addition, the ETS 5M is ideal for high evaporating temperature Computer Room Air Conditioners (CRAC) with direct expansion.

    the knowledge gained from the information in these videos can be put as skills in my CV 😅
  • @BirdmanHT07
    I am a controls tech, one of the colleges near me has a newer wing with a VRF system in it. Doing building automation, I have a pretty good understanding of commercial HVAC but these videos are great. Started watching the channel because I did an Electrical engineering technology course at college, and was watching your electrical videos for fun. Then stumbled onto your HVAC section, amazing. I'm buying you a coffee.
  • @JohnnyJr396
    Just sent you a little appreciation. Thanks for this video. I’ve watched a few try to explain and even they stumbled. You truly are a master at explaining complicated tech.
  • just perfect. Thank you so much! As a building sustainability consultant coming from an architecture background, I need such knowledge badly since they are very important for building sustainability but we as architects don't have it.
  • @Nayan133
    I think this is the sufficient video ever at starting stage to enter into the profession or research on refrigeration & heat pump field ❤️.
  • @EGBROWNSB1987
    I worked on city multi units before but always thought of them as more heat pumps than VFRs thank you for this video
  • I work as a refrigerationist and this is pretty interesting for me being a total beginner, it's a game changer
  • @GururajBN
    I have a split air conditioner in my bedroom. I use it only in summer months. It runs up huge electricity bills. Now I understand that it is not a VRF system. Good old AC which steadily consumes power as long as it is on. Very instructive video.
  • An excellent presentation, simple, easy , clear and covers all the important details. Thank you for this great job.
  • @AJ-ox8xy
    Holy smokes. This is the first time I've heard of these systems. I always wondered if it was possible. That's so cool!!!
  • @rolliebca
    Such an excellent video explanation of this complex system. Thanks!
  • @MrPaolosio
    MSc student using dynamnic simulation modelling which includes HVAC - this video is very useful - best yet from you i think :)
  • Having you and Bryan on this site has made this apprenticeship an absolute breeze.
  • @mitulshetty3736
    Thanks a lot for this amazing explanation, really got me thinking about getting in the HVAC sector.
  • Very concise simple to understand explanation of a very complex process. Great information.
  • The graphics on these vids are fantastic. And very well explained.👍👍👍
  • @erick_bst
    I used to hate to work VRF systems until I understood how convenient and easy are to work on and to retrofit on old buildings.
