There’s a lot of those in Taipei. Everything north of Yuanshan station, all of yellow line, and brown line.
As for Kaoshung, I don’t know, maybe petition the mayor or something.
And maybe Taiwan needs to build more nuke plants so we don’t have to have ridiculous rules about AC temperature.
The Taipei Blue line is excellent , it’s a pity the other lines could not have been as good.
If AC should make sense in MRT stations than they need to shut down the ventilating system. You can not just circulate air in an MRT system.
Not sure what you mean by that. AC and ventilation systems are one and the same. Sometimes (rush hour in the summer) AC & ventilation is on in the stations, other times only the ventilation/fan is on.
No, AC is a closed system, ventilation is open and outside air is used.
Ventilation is necessary. It’s underground and there’s no way air can get in otherwise. If you notice all kinds of weird towers and stuff next to MRT stations (or ghost floors if the station entrance is part of a building) these are ventilation tunnel discharge.
Otherwise the air inside can become deadly in hours.
I live practically on top of the MRT. The station “exhales”, a burst of wind expelled by the train when it pulls in. Usually a lot cooler than outside.
No it’s not. That would be extremely unhealthy and potentially dangerous and fatal.
Air conditioners suck in fresh, hot air from outside, makes it cold, then spits it into the building via vents, while at the same time hot air from inside the building gets expelled outside via exit vents.
AC contains ventilation, so you don’t need to open your windows like Taiwanese people tell you.
Actually ductless AC (basically mini splits) are a closed system. It just blows air over the evaporator coil that gets cold when the compressor is on.
But a typical room has enough air exchange with the outside that this doesn’t matter, but cooling outside air (which is over 37C) to indoor temperature uses a lot of energy, and so it’s better to cool air that’s already cool to begin with.
I was mostly talking about HVAC systems at MRT stations, but even window units ventilate by sucking the hot air from your room through the front panel, and expel it out the window through the back.
But what are mini-splits? The AC in my room has a unit inside, and a much larger unit outside that expels hot air, and they are connected via a hose. Hot air from my room gets expelled through the back of the outside unit.
And where does the air come from?
That hose does not contain air, it’s a bundle of pipes for the refrigerant fluid and some wiring
Half of the red line.
All minus two stations of the brown line.
all of the yellow line.
Yeah, like @ponlaihop said, that’s not the hot air from your room. (How would it selectively extract “hot air” anyway?)
I’m guessing Songshan Airport is one (?), but what’s the other one? Dazhi maybe?
Yeah
Light rail lines are also above ground. Elevators are basically ovens.
Heat rises, and the “hot air” vents are usually in the ceiling, in buildings that use HVAC systems.
Yeah, hot air rises, but the average air temperature distribution in a room is a gradient at best, not a static layer of hot air sitting at the top of the room waiting to be sucked out through the AC and blown outdoors through the refrigerant pipes, and it’s being continuously agitated by the AC fan. It’s not the same air exiting the compressor unit. The heat from the room is being extracted by the indoor unit using the indoor air to evaporate the refrigerant.
Are you talking about the home split units? Having a hard time keeping track.
Yeah, I’m talking about home split units (which TL brought up and you continued, as far as I can tell).
