I have that, and it's better than what I experience when I travel in cars where the driver has to switch the a/c on and off in a vain attempt to maintain comfort. -- Gordon H Remove "invalid" to reply

Warm aircon sounds like a contradiction in >> terms. It's what makes the difference between "full" air con and a cooler/chiller. The cooler always works at full capacity and only switches off when freezing of water vapour could cause damage to cooler matrix (about 3�C/37.4�F air exit temp). You really don't want to sit in a box at 3�C/37.4�F for very long. All cars with "climate control" have heat as it has to heat the air back up to desired temp. AFAIK UK is the only market in the world that demanded and got "solair" - sunroof and air con as a standard fitment. Anywhere else in the world would have to buy a car with air con and have the sunroof fitted by the dealer as an option. > major manufacturers such as Ford have the system set so that air con. >operates automatically if max. demist is selected. Car ventilation systems have different arrangements depending on market. eg from a factory service manual Setting , not UK/EU , UK/EU Vent, 100% dash vents , 100% dash vents B/L , 60% dash vent / 40% floor , 64% dash vent / 36% floor Foot , 63% foot / 37% screen , 50% foot / 22% screen / 28% vent Def/foot , 50% screen / 50% foot , 41% screen / 38% foot / 21% vent Def , 100% screen , 72% screen / 28% vent. There was no setting on UK/EU vent system that stopped dash vent flow. And it doesn't stop at vent systems, if you buy a grey market / import car you may not get everything a UK/EU car has. Like engine oil/water heat exchanger, diff oil cooler, trans cooler (300ZX had cooler on manual transmission for EU) etc. This can affect how the car copes with higher average speeds in EU. Cars sold in Germany often have solenoid loading devices to reduce screen wiper lift at speeds in excess of 75mph. Aerodynamic devices that operate at 70mph in EU are adjusted to work at 50mph in UK. Japanese car engine's cooling systems may not have capacity of EU/UK system as it only has to cope with engine management system limited 180km/h (112mph) max speed and repeated accel/decel still can't overload it. Even in the UK there can be local variations, cars sold in Scotland often have an additional petrol fuelled Scandinavian type heater fitted (I'm not sure if they are getting Swedish/Norwegian spec cars or if this is a dealer option). -- Peter Hill Spamtrap reply domain as per NNTP-Posting-Host in header Can of worms - what every fisherman wants.

Whether the resulting drag cuts the mpg more than the a/c is open for debate. -- Gordon H Remove "invalid" to reply

You can't be thinking of air conditioning. Here's a picture of an air conditioner: http://www.walmart.com/ip/12000-BTU-Frigidaire-Air-Conditioner/10999795 It doesn't heat the air or humidifiy it. It only cools it and dries it. >Air conditioning in general (not necessarily automotive) terms means >everything I list above; Apparently not. > "climate control" means having an automatic >control system to mange [sic] all of that without user intervention. No, "climate control" is controlled by the user according to desired comfort levels. How can you people know anything about air conditioning anyway? You don't have it in your homes, and you don't need it. |
