Talk:Automotive air conditioning

Missing information

I hear that somehow there are vacuum lines that are an integral part of modern automotive air conditioning. I wish this had explained that. 98.82.3.150 (talk) 12:12, 24 May 2012 (UTC)

Well, you may think this is of "low" importance, but I'm still trying to understand it. 98.82.3.150 (talk) 17:13, 26 May 2012 (UTC)

I was here for some specification like size measurement of the car A.C. and much more. hope i will be able to find these missing information in the nearest future. — Preceding unsigned comment added by 223.176.173.132 (talk) 11:02, 28 April 2016 (UTC)

Non-comprehensive introduction

The article opens by discussing the air conditioners affect on fuel economy. While informative, I was hear for a historical introduction and found it odd to open with this information. — Preceding unsigned comment added by 169.226.37.56 (talk) 16:49, 6 December 2013 (UTC)

History Lesson

This speaks of the air conditioning systems of the past but nothing of the current design, the compressor mechanisms, or any more technical info, and is close enough to a stub. Needs review. 68.62.204.18 (talk) 17:14, 27 July 2012 (UTC)

This article was spilt away from the much more detailed Air conditioning article -- see the edit here as of 14:58, November 30, 2011. Perhaps it is currently not complete from the technical side of automotive systems, but the discussion about the history of automotive A/C has about 20 references. This is more than normally found in stub ranked articles. This is probably good enough for a start, but please contribute more information to this article! CZmarlin (talk) 01:03, 28 July 2012 (UTC)

I added some basic information on operation principles (because at least those should be given here, I think). Noggo (talk) 12:53, 23 July 2014 (UTC)

After-Market Companies (History)

Three Texas companies entered the market in 1948 with A/C kits for premium cars such as Cadillac, Oldsmobile and Chrysler. These companies were: 1. A.R.A (Automobile Refrigerated Air conditioners) of Fort worth, 2. Lone Star Oldsmobile & Cadillac of Dallas (quickly changed their name to Frigikar) and Mark IV of Dallas. These companies rode the explosive demand generated in the Southern United States due to the lack of any factory options coming out of Detroit. 10,000 units had been shipped,collectively, by the time Detroit offered the first factory-air cars in 1954. Most of the kits were either installed in customer cars or through car dealers, and were exclusively trunk mounted. The 1950's and 1960's ushered in continuing marketing battle between the automobile manufacturers and the 'Upstarts' who grew to at least 30 companies in the North Texas area, as well as other locations, mainly in the mid-west. In spite of rapid growth of factory-air units coming out of Detroit between 1954 and 1970, the millions of cars still on the road kept the after-market producers busy well into the 1980's Starting in the early 1950's the after-market models became almost exclusively 'Under-Dash' versions and increasingly custom-tailored to fit various brands and models.Rodmaru (talk) 22:58, 22 January 2015 (UTC)

Power consumption

<

In a modern automobile, the A/C system will use around 4 horsepower (3 kW) of the engine's power, thus increasing fuel consumption of the vehicle.[27]

>

Even after reading all the way through reference 27 twice I cannot see where the '4 horsepower' figure is supported - could someone more knowledgable (or more literate) help me out? 109.145.108.156 (talk) 19:50, 25 June 2016 (UTC)

Yeah, followed the source for a dissertation of mine, and it only mentions the author is modelling a hypothetical a/c system with an electrical load of 3kW, can't find where it says thats a usual electrical load... 137.205.0.160 (talk) 06:24, 14 November 2016 (UTC)

< The maximum thermal cooling load was assumed to be 7 kW. The net coefficient of performance of the electrically driven air-conditioning system, including the efficiency of the compressor and the electric motor required to drive it, was assumed to be 2.33. This yielded a maximum electrical load (resulting from air-conditioning) of 3 kW > 86.135.129.88 (talk) 23:35, 24 December 2019 (UTC)

Types of Automotive Air Conditioning Refrigerants

With a new type of air conditioning refrigerant that has recently hit the market, I added information on this new automotive refrigerant, R-1234yf. Along with this, I added information about the other types of automotive air conditioning freons present and past, and history of the refrigerant R-12. Readers need to understand the different types of automotive refrigerants and their impacts on the environment.--DWilliams37 (talk) 23:41, 21 February 2024 (UTC)
