New Wright double deck body

The quote was from
http://www.wrightbus.com/archive.asp?type=News%20Release#

and the batch should have been delivered late 2004, not earlier this year, apology if needed.

So as you said, Yoram, an air-cond. bus should have no opening windows at all, even with an air-cond. unit.  How would you identity the ex-Airbus, now with First, Olympians then??

I couldn't find anything so-called 'air chilled cooling' in the encyclopedia.com.  Is there any suggestion for more information about the system from any official websites or readings?

2. a true air conditioning system would cool down to preset CONSTANT temp, and have a special air conditioning plants on the bus, and, externally, the bus would have non opening windows. [and I refer you to KMB NEWs of April 2005 and June 2005[about AL1] which discuss the issue of air conditioning on buses.

Well, no. Those which maintains a constant temperature is known as "climate
control systems" - at least that was what car manufacturers normally call them.
The "chilled air system" is on the WVLs are just a type of air-conditioning, albeit
having a smaller compressor comparing to the bigger systems used in HK.

Guys, don't be fussy about the terminology. Those WVLs may not look as appealing
as the HK equivalents, but they are still, technically, air-conditioned.

Dear Lams and NV58,

The term 'air conditioned bus' is 'sensitive'. in London. The reason is that many people and  the LTPB wanted TfL to introduce truely air conditioned bus, in the style of Hong Kong.
This is very expensive, and for services that are paid for by subsidy, it is not economical.

I do not want to argue too much about terminology either. I agree it does not serve any purpose. As it happens, I have just been sent photos of the interior of the new buses- upstairs.
The bus has a combination of ventilation/air cooling system and not a proper air conditioning system, Hong Kong style, with machinary at the rear [therefore you need a 3 axle bus to support it].
It appears to me that the systems tried on VE953 a few years ago [and failed!], several TAs at FW- L United, and now the two different systems for Wright- one tried for East Thames and the different one for AF garage all have something in common- try to find a system which will cool the air a little bit by increasing air circulation and a device to 'chill' the air .
Those are not true air condition systems but a hybrid. and I am sure that we will see more such systems in trial.

I hope we can all agree on that, and be friends again!

regards,

Yoram.

sorry, I forgot to add about the compressors! NV58 is right of course! it is the 'power' of the compressor that determines how 'good' the air condition system is. apologies.

The compressors for the various systems on trial in London is far too small, as far as I am aware, it is less that a large flat would need for an effective air conditioning unit. It is being combined with other technology to create some sort of a hybrid air cooling/chilling unit.

regards

Yoram

The compressors for  ...

Yes you are spot on, that's why we say they are air-cond afterall - not a bad
consolation after all the Routemaster withdrawal!

The compressor is small under the fact that it uses the cab air-cond unit, as
the press release from Wright, which smal has forwarded earlier in this thread.
Having said that, it seems to work fine, much better than the systems used by
East Lancs (on VE953, the EVLs and those Glasgow B7LTs). But as smal sadly
pointed out, how much longer they remind working would be for all to see...

Anyway, it's just a rather enthusiastic discussion, no worry. I was a bit thrilled
when I got on WVL196 first time on Friday - but what a shame it doesn't work
at the lower deck.

cool, thx for the explanation.  no worries about the arguement.  We argue to raise our points then we learn from it.  We might argue with fds, and even couples, father-and-son will argue too.  There's a saying in Chinese "We will know your friends better after the fight."  and I always believe in it.   #   

We argue about 'a point', we never pick on any individual and that's the fun about an argument.  Dun worry bout it yoram, tomorrow this time, we will all forgotten about this so-called a 'fight'  hahaha~~  At the end of th day, it's only a bus #  

I will be keeping an eye on ya around London and reading uploads of yours very-odd oddities.  #:D  

It is 'truly true', yoram, that running air-con buses in London / UK is not economical.  A fleet like the one in Hong Kong is just incredible.

I have seen pics of TA231 in the LOTS mag.  It do look funny and I wonder how workable that ventilation system will be.  Must make a trip down there sometime.

Lastly, the current performance of the new batch, I personally think, are reasonably good.  Do ride on them if you have the chance yoram.

cheers for now :
