完美的淋浴温度,为何如此难寻?

Why Is the Perfect Shower Temperature So Hard To Find?

完美的淋浴水温为何如此难寻?
QQs: Why is the perfect shower temperature so hard to find?
除了温度刚好的洗澡水
Few things in life are quite as satisfying
生活中没有更能令人心满意足的事情了
as standing in a shower that’s exactly the right temperature.
可好景不长
But that heaven never lasts forever.
水温一会儿就凉了
Water starts to get a little cooler,
所以你稍稍调整了一下控温旋钮
so you turn the temperature knob the tiniest bit,
突然一阵滚烫的热水扑面而来
and suddenly you’re being scalded in places,
让你着实不想再次经历
you really never want to be scalded.
你想把旋钮调回去
You try to turn the knob back
接着又被冰水浇了一身
and then you’re being drenched in ice water.
旋钮上有那么多温度可以调节
There’s plenty of room for the knob to turn though,
为何只有一丝空间
so why is there only one miniscule spot
留给适合人们洗澡的水温?
with the water temperature is fit for humans?
关键在于 大部分的楼房
First problem is that in most buildings,
热水都在中央热水器里加热储存
the hot water is held and heated in a water heater.
而在冷水中掺入滚烫的热水
Adding really hot water to cold water, changes the temperature more
要比只掺入温水 水温上升得更快
than adding the same amount of water that’s just warm.
因此 如果水温过高
So if the water is too hot,
运给你的一点点热水也会导致
tiny changes in how much hot water is sent your way
混合后洒在身上的水
can lead to big changes in the temperature
水温骤变
of the mix water hitting your body.
况且 加热器里的水 温度通常非常高
And the water in water heaters is usually very hot.
为了杀菌 一般设定在50℃左右
It’s generally set to around 50 degrees Celsius to kill bacteria.
你当然可以关小一点
Although you can often turn that down
这样就有很多适合的温度可供选择
to give you a wider range of acceptable shower temperatures,
只要你不在意那些未被杀死的细菌就行
assuming you’re okay with the risk of said bacteria staying alive.
但有时候 即使水不那么热
But even with water that isn’t too hot,
热水器的控温旋钮
the spots on your temperature knob
仍然无法保证给你一致的水温
still aren’t guaranteed to give you the same water temperature.
一方面是因为 小型热水器水量不足
For one thing, small water heaters might not hold enough hot water
无法支撑长时间的热水澡
at any one time for a long, hot shower.
较新的楼房规避了这一问题
Newer buildings sometimes get around this problem
按需求烧热水
by heating their hot water on demand
而不是只用一个热水器
instead of holding it in a water heater.
但很多管道其实并不检查
But a lot of plumbing doesn’t actually check
冷热水混合后的水温
the temperature of the hot cold mix,
只是单纯释放定量的冷热水进行混合
it just opens the hot and cold pipes by the right amounts.
因此 如果你在洗澡时
So if someone uses some of the cold
有人打开其他水龙头用冷水
at another faucet while you’re in the shower,
你就会突然迎来一阵滚烫的热水
you get a burst of just hot water hitting your skin.
而且热水器的水温设置得太高
Combined with a water heater that’s set to high,
也让完美的淋浴水温
that makes the perfect shower temperature
成为难以企及的目标
a tiny moving target that’s almost impossible to hit.
安装压力平衡阀
This moving target problem can mostly be solved
能大致解决这个问题
by installing a pressure balancing valve,
它能减小热水输出
which will turn down the hot water
以抵消冷水水量不足的情况
if the cold suddenly slows down or disappear.
更新型的恒温阀甚至也能
Even newer valves called thermostatic mixing valves give you added control
通过一个特殊的恒温调节器
over both the temperature and pressure of your shower
控制淋浴水温和水压
using a special kind of thermostat
恒温器能根据周围的水温改变其大小
that changes size based on the temperature of the water around it.
如果别处正使用冷水
If the cold water goes somewhere else,
比如冲厕所等情况
like to a toilet that’s being flushed,
多余的热水会让恒温器扩张
the extra hot water makes the thermostat expand
直到被完全阻隔 无法输送给你
until it blocks more of the hot water from getting to you.
而当水温过低时
And when the water around it is too cold,
恒温器则反过来隔绝冷水
the thermostat contracts blocking more of the cold instead.
所以屋里有人小便时
So other people in the house get to pee
不会再烫到你了 蛮好
without burning you, which is nice.
你只需要调节控温旋钮
And all you have to do is set the temperature you want
到一个理想的完美水温就行了
by turning your showers dial to the perfect temperature,
你也就能省下调水温的时间
which means you can spend less time adjusting
去尽情放松 泡澡 怎样都好
and more time relaxing or bathing or whatever.
