a new form of heat exchange equipment?

[Adsibob]

Lepidó has been described as “a new form of heat exchange equipment”. But isn’t this just a variation of MVHR?

Yes...

Enjay's technology is larger than conventional heat exchangers and is designed so that the grease and soot particles flow past the metal coils inside that transfer energy, instead of sticking to them, says Mr Speerfork.

 

...With a Teflon coated heat exchanger? 🙄

Lepido, being a heavy-duty heat exchanger, is larger compared to a traditional heat exchanger to make room for its patented geometry of the recovery coils. The space between the coils is much larger than between fins of a traditional heat exchanger.

 

Not even Teflon then. I wonder if this could be enhanced by  electrostatic repulsion?

It is always worth checking a products name.

From now on I shall call it the kiddy findler.

Le Pedo, my arse.

Yes it does seem to be an industrial scale mvhr recovering heat from the kitchen ventilation system.

 

I guess the biggest challenge and why this is "new" with it's new design of heat exchanger, is the high grease content of the exhaust air it is recovering heat from.

 

One can imagine a condensate drain that is collecting cooking fat?

I am always amazed how little fat there is in our extraction system.

The baffles on the ranges seem to do their job, even though they seem very basic in design and are probably not really designed, more guessed at.

We probably though away 40 MWh of energy a night though the extractor.

I had to do a job at the local Chinese takeaway.  It appeared at least half the baffles are missing from the hoods with the innards of the hood and extract pipe clearly visible, so I bet they get a lot more fat up their chimney?

 

I can well believe the massive heat loss / waste, there was quite a long line of cookers all with the hoods and extraction above them.

Between 15 and 60 ACH, anb the air leaving is not at 22⁰C like a house.

Last night we were at a very pleasant 30⁰C. In a month, probably high 40s.
