My question is, why do you need air conditioning in the UK? It's almost July and I'm contemplating putting the heating on cause it's 10°c outside.

MaxFist It's more of a commercial and city thing. Places with lots of people or equipment like computers spewing out heat gets to be a big problem even outside of summer time in some cases. For the average house that on average hase fewer people living in it then rooms an no heat intensive equipment outside the kitchen it's not such a problem.

This does not save a single kWh, it is only peak shaving to save the grid from collapse. It only delays the demand for an hour, the work still has to be done. If your grid is this close to disaster, you need to build some more power plants. Hotels and hospitals are not to blame for the problem, but they can help by starting up their diesel backups. Put the parliament building at the top of the list to be shut down.

The problem is that AC units are typically on or off. This is inefficient. The solution is VRF (variable refrigerant flow) AC units. With that technology, you can more accurately match the AC output to remove just the heat gain of the building and no more. Another big advantage of VRF is the ability to remove humidity without excessive cooling.

@MauroTamm
@MauroTamm 9 лет назад
gollumondrugs there is no saving at all - just load distribution. Turn off ac for an hour - means that it will have to work harder to break even and normalize temp after you turn it on - using more energy.
@FakeButt
@FakeButt 9 лет назад
Mauro Tamm Well if you can manage your power consumption efficiently it's a kind of saving. And the AC will have to work harder afterwards but it will be doing it when there is enough energy. I guess when there is a peak of demand they will need to turn on more generators (or import energy from another country if that's an option) and keeping additional generators running or ready or running them for a short period of time is not efficient.

Then what happens when you turn it all back on? It has to run longer to get the temperature back to where it would have been if you hadn't turned it off. Heat transfer is the same, no matter how you schedule it.

What About safety of those appliances? reducing electricity or shutting it causes electrical malfunction(burned fuse) also food safety might be effected if fridges were part of the system. other electrical appliances can't take the reducing in voltage and get super heated very fast. I think on the long run this might be a good idea if appliances were made to adjust performance according to available resources..
@Rickmakes

My utility (in the U.S.) has this for residential customers. They put a remote shutoff on your AC so they can shut it off during peak times. It is optional and you get a credit each year for having the system. I don't personally do it as I don't want the utility messing with my AC.

Very large power users have been doing this for years. When the grid is under stress the frequency drops. When it falls from 50.0hz to say 49.8hz big users, cold stores , pumping stations etc start to trip off. By the time the frequency gets back to say 49.95hz they start to come on again, by that time national Grid will have spun up a pumped storage station or 2. In the the depths of winter it happens every day.
@CristiNeagu

How can this be the solution? If this is the best you can come up with, you aren't trying very much at all There's a reason why all those buildings are using power. Have you tried turning off the AC at home for an hour during mid summer? You'd cook yourself. Now put hundreds of people in that situation, people who need to work. That is not very efficient. Add to this the fact that to ensure best longevity it's best to never turn off electrical equipment, you're looking at major losses in the long run. This isn't an option. This is some hippie BS. Just like that Earth hour. Have you any idea what taking off the grid so many consumers does to it? It will suddenly produce way more power than is needed, and will start failing and burning people's electronics. There are 2 solutions. Either make more efficient consumers, or more efficient power production. As time moves one, electric appliances are becoming more and more efficient. So that is sort of taking care of itself. As for the production, there can be only one solution at the moment: nuclear power. Which is where we encounter some more hippie BS. All these ignorant people who are so eager to compare any nuclear power station with Chernobyl and Fukushima. Have they even heard of CANDU reactors? Why are we not funding this? Why aren't we funding clean, efficient, energy production? Bang goes the theory, indeed, when you start looking at actual facts.

@sandwich2473
@sandwich2473 9 лет назад
***** In any building I've been to, you can turn the heating off for an hour and the temperature won't drop very much. The hot water that flows through the heaters doesn't instantly go cold when you tunt off the heating. It's still a cool way to slightly reduce power load at pek times.
@CristiNeagu
@CristiNeagu 9 лет назад
EngeKomkommer I don't have AC in my home either, but what i can tell you is that if you're used to living with AC, turning it off is not pleasant at all, especially if the house you live in wasn't designed to have natural circulation. ***** I will assume that you mean to shut off heating during the winter. And no, this is not equivalent. Because in the winter the sun's rays don't freeze whatever they fall on. During the summer you have a greenhouse effect indoors. What is the equivalent mechanism during winter that cools down a house rapidly, even with the windows closed?
@CristiNeagu
@CristiNeagu 9 лет назад
***** _"WHAT??? no insulation is perfect, any house will leak heat during winter"_ How long does it take for a house at normal temperature to cool down to an uncomfortable level in the winter, and how long does it take for the same house to heat up to an uncomfortable level during the summer? Because from my own experience, heat inside a house at winter will last for at least 8 hours, while the same house will heat up to an unbearable level in 1 hour or so. How can you even compare these two scenarios? _" the cost of maintaining equilibrium is always the same - simple thermodynamics."_ It's not the same, actually. You need to take into account the means by which energy is delivered to either heat the house in summer or cool the house in the winter. During the winter all you have is cool air outside, cooling the windows mainly who cool the air inside the house. Also, cool air might be leaking through. This is analogous to the summer, where you have hot air heating the windows and in turn, the air inside. However, during the summer, you also have the sun's radiation creating a greenhouse effect, heating the house much much faster. Heating in the summer occurs much faster than cooling in the winter. _"the energy requirements, again all things being equal, are the same."_ But all things aren't equal, because the sun does not freeze things in the summer. In any case, this whole point is irrelevant. It doesn't matter if you cool the air, or heating it up, or whatever. Office buildings need to be ventilated, no matter the season. You have hundreds of people working in tight quarters, usually a long way away from any windows. If you turn off AC and ventilation, you'll be suffocating those people.
@CristiNeagu
@CristiNeagu 9 лет назад
And i am still kinda perplexed why we're arguing about heating and cooling and whatnot, and not discussing the actual issue. The solution these people found has a lot of problems, and it won't work in the long run. Efficiency is the key, both in producing the power and in using it.

***** You have to understand that the grid operates in "real time" so to speak. There is hardly any energy storage systems in place to store power for when it's needed therefore if power isn't being used then its wasted. This will reduce costs for now until there is better implementation of energy storage devices e.g. Tesla Powerwall becomes a mainstream technology.

@toleth88

Formulka In the typical sense you are correct, but when it comes to large buildings the air conditioning units are used for heating/cooling, cleaning the air (filtration), air circulation and increasing/decreasing humidity. They units they use are not typical A/C units, they have a different name, cant remember what it is though. Air conditioning generally just refers to something that alters the air in some way.

Ahhh the grid, the precious, overtaxed and under planned grid. About 10 years ago in the US we had to go to those lovely, curly cue Fluorescent light bulbs to save our pour grid from collapsing. And now they want everyone to ditch their IC automobiles and charge their new, battery operated cars on the same grid. I wonder what the load used to re-cool all those buildings will be? wouldn't it just be better to set an agreed upon minimum temperature? Or, and I know its not as sexy as mandating art work per capta, maybe just updating, re-enforcing and re-powering a grid that is under engineered for the demands of the future? Quit playing shell games and fix the problem.

@SoYFooD2
@SoYFooD2 9 лет назад
this is a bad explanation of what that companie is about. if u have a average of 100 power plants of drain but have peaks of 125 plants u will need to have 125 or more running wile a our later the demand can be just 75 plant. having 50 plats idel (or reduce production) will hurt efficiency cost en co2. because nuclear power needs more than a hour to go from low to high production. most green energy will deliver power on a irregular base and are not 24 hours available. so when u have a peak of 125 u turn of say the ac an friges en let them run dubble time when the load is 75. u can even pre cool a bidings when it is windy en sunny when the forecast is a windlus cloudy afternoon (in essences storing power from the grid witch is a practical inposebilety now). sry for the grammar im dutch.
@theq4602
@theq4602 6 лет назад
Heres an idea already being tried. Hydroelectric plants that pump up water into reservoirs using grid power during low demand hours. Then during high demand peak load you run the dam in reverse and get lots of power when you need it. No need for batteries.

"Turn off the AC for an hour and save energy" Doesn't she realize that the moment they turn the system back on there's going to be a spike in power consumption as the AC works harder to normalize the temperatures again? It doesn't save energy at all, it merely reduces grid load when there's a high demand. Don't get me wrong, reducing grid load in high demand is still good because they they don't need to fire up more generators to cope with the spikes in demand. Generally those generators are run on fossil fuels which have a greater impact on the environment than nuclear, wind or solar power. (where hydro hardly applies in the UK) But i can't take anything she says seriously when she misses such a huge flaw in logic. It's comparable to stating that "if i turn off my car for one hour during my 4 hour trip i will save one hours worth of fuel!" No, it just means you delay the useage of that fuel by one hour. It also means your car now spends another heating cycle which draws more fuel than if it drove non-stop for 4 hours. I'd even dare to say, this system increases energy consumption in the long run for that same reason. AC draws more power the harder it needs to work in a nonlinear fashion.
@SuperSilkyJohnson
@SuperSilkyJohnson 9 лет назад
Cadde I think the point is that they spread out the usage over time, while they may shut off every air conditioner under this system during extreme peaks not everyone will be under this system, the air conditioners are then turned back on as the peak subsides.

@JallenMeodia
@JallenMeodia 9 лет назад
***** We lack the ability to story vast amounts of electrical energy, the only way to deal with energy spikes before was to increase production which when the spike had subsided all that energy gets wasted. This way we can deal with spikes more efficiently (and cheaply). The famous example is people turning on kettles during ad breaks of favourite shows. During the 2002 England Vs Brazil world cup match an extra 2570 MW was needed during half-time. Companies had to predict this and generate more power to meet demand, and it's not as simple as flipping a switch, this is. If this system had been in place we could have instead cut unneeded power elsewhere. It's very a clever idea and a good stop gap in along the way to a more energy efficient future.

From the looks of it it's a private company doing it, so it's not really about how much it costs, it's obviously self-sustaining. I understand that we need more energy, but there are companies wasting megawatts of energy on things that make no difference, so that sorta gives us more energy as it's energy we didn't have before.
