Some of my best friends live in Karachi. As a city it amazes me: the entire population of Australia in a single city. Yes, there is misery here too, and pollution, overcrowding,... and Close Comfort.
Importance of Portable AC in Karachi
Only the extremely wealthy in Karachi can own their own home. Most people rent their homes and the last thing they want is a fixed air conditioner in every room that they have to leave behind, or risk damaging if they take it with them to a new apartment.
The strong sea breeze in Karachi is a split AC killer: the salt-laden air corrodes the thin cooling fins in just a few short years, and clogs up the fins long before then with a lethal combination of salt and dust.
Ever heard of the urban heat island effect?
Watch this video about Singapore;'s urban heat island effect and realise that Karachi is like that too!
Cities are hotter than the surrounding land just because of air conditioners. Every air conditioner, every car, every vehicle, all of them are heating the city relentlessly. Every kilowatt of electricity ultimately appears as heat in the city. Every air conditioner makes everyone else just a bit hotter, and raises the running cost for everyone too! Except Close Comfort.
Close Comfort is the ideal solution. Releasing only 300 Watts of heat, four to eight times less than normal portable and fixed ACs, Close Comfort costs almost nothing to run, and does not heat up everyone else at the same time. And Close Comfort does not have an outdoor module exposed to the salt and dust: it will last for years and years.
In a city where you can only dream of sleeping under the stars, Close Comfort can bring convenient, economic, comfort that helps improve the environment for everyone.
Global Warming Too
And it's not just Karachi.
Cities around the globe, especially in warmer climates, are accelerating global climate change and heating of the planet.
Until the 1950s, homes in Karachi were designed to shield people from the heat of summer. They had thick walls and high ceilings with ventilation. Doors and windows were open to the cool breezes at night, and the thick walls absorbed the heat of the day long enough for people to feel comfortable.
Even the traditional katcha houses did the same: they were cool and comfortable, though more difficult to maintain and keep clean.
Then air conditioning and "modern building" styles arrived in the 1960s. Air conditioning allowed architects to builders to create lazy designs that accumulate heat in summer (and can freeze you in winter: just ask Lahoris!).
Sadly, most of Karachi today reflects lazy building, totally unsuited for the climate. So what do people do?
Install split air conditioners.
And then worry for ever more about electricity bills.
And then lose their natural acclimatisation to Karachi's long summer heat!
And lose their cardiovascular fitness than comes with exposure to heat.
And suffer all kinds of ailments because they breathe stale recirculated air, not the clean fresh sea air off the Indian ocean.
So they are even less able to cope without air conditioning, and they turn down the thermostat, and then the electricity bill climbs even more, then their worries accumulate, and ....
And this is happening around the world right now.
Leading scientists predict that, by the end of the century, if we don't do something now, the world will warm by 3-5 degrees, much of that caused just by split air conditioners that ruin people's health at the same time.
Close Comfort is the ultimate solution. I developed this technology for cities like Karachi and I use Close Comfort myself all the time I can when in Pakistan.
