Heat Recovery VRF System - How it Works

Who makes residential units for this type of system?
My hope is to explore thermal storage, and these systems seem to have all the requisite components.

I’ve worked in these system and is the most annoying thing to understand

More videos on VRF

Very niece sir 😘🇮🇳

These videos are class and funnily enough explain it better than Daikin who invented the VRV(F)

Thank you 👍

I work on engineered systems. Energy management environmental control. Two pipe for pipe blended, mixing boilers chillers .. I do see a need for these where grade is a challenge for a retrofit or an addition

hi @Engineering Mindset , can you make a video of capacitor in AC circuit

Thanks for the great video. Are there any domestic systems that do heat recovery? I'd love to be able to cool my house and reject the heat in to the domestic hot water system or the pool but all the HR systems I can find are too big for even a moderately large house

Ditels component 👌👌👌👌👌👌
Please sent next video,
Dibot /mosfet /resister /capacitor /
How work and test and use🌹

Please ditels video ? Mosfet work and use?

Nice video

It was very useful video👍🏻

they should make a deep freezer that heats a house in the winter

Please darkness sensor

excellent production!

Very well explained. Thanks for sharing.

Heat Recoveery? 😅

have you actually worked on any of this equipment or just theory

I work on water cooled / air cooled chillers, RTUs, VaVs, split systems, mini splits, boilers, furnaces and VRF systems. VRF is one of the most complicated things you can work on HVAC wise, in theory they are a good idea but they break down a lot more than other systems and some VRFs have triple or quad coils and if you have to change one you have to change all 3 or 4 and littarly take the entire unit apart all the controls you have to have a hand held to shut off the valves just to transfer the gas, especially if it's like a citi multi-pipe they are hell to work on. We were going to do a system that had a leak on one of the coils they told us we had to buy all 3 for 70,000$ or a new system for 100,000 it would take almost 2 or 3 days with guys who know what they are doing to change the coils out it's really labor intensive

Heat Recoveery

Great short examples on HVACR systems.

I am going to be controversial and say that large central VRF systems are not the future.

I truly enjoy your videos for explaining a variety of technical subjects in a concise and illustrated way. Not having much background in HVAC, perhaps in the future you could spell out the acronyms for us non-refrigerant types? Something written in the summary underneath the video and articulate it at the beginning of the video would be great. 🙂

Great video. I worked with heat pumps and large Commercial chillers and Building automation systems and variable speed compressors and the key is to have a VFD variable speed compressor to be able to run at low loads. Plus they are a lot more NRG efficient than conventional split phase compressors.

It would be interesting to see for this type of AC that able to change heating and cooling. Also, how fast refrigerant liquid turn into gas prior enter the compressor which is in reverse direction.

Thanks for the information

Nice

Thank you for what you provide for us 😊
