An aquarium chiller and heater in one, for the whole year. It goes on the filter's return hose, outside the tank. One thermoelectric element pulls heat out of the water when the room is hot and pumps it in when the room is cold, and holds the whole tank at the temperature you set. Nothing in the tank, no heater to swap out when the season turns, and no copper anywhere the water flows.
安澜，鱼缸冷暖机，一台管全年。接在过滤器的出水管上，装在缸外。同一片半导体，房间热的时候把水里的热搬出去，房间冷的时候把热搬进来，整缸水一直守在你设的温度。缸里不放任何东西，换季不用拆加热棒，水路不碰铜。
Accuracy and energy figures come from the studio's water-loop simulation, with the real control software in the loop. Measured figures replace them before launch.
精度和耗电数据来自工作室的水路仿真（跑的是真实的控制程序），上市前以实测为准。
Heating is the same heat pump running backwards, not a resistor. A heater turns 1 kWh into 1 kWh of heat; in a winter room AquaComfort puts 1.5–2.2 kWh into the water for every kWh it draws, fan and electronics included (simulation).
加热就是同一个热泵反过来抽，不是电阻丝。加热棒 1 度电只能变成 1 度热；冬天里 AquaComfort 每用 1 度电，能往水里送 1.5–2.2 度热，风扇和电路的耗电都算在内（仿真）。
No metal cold plate: the water flows straight over the element's ceramic face, sealed by a food-safe gasket. Copper, zinc and aluminium ions are toxic to fish and shrimp, so none of them are in the water path. In the standard version the one metal part is the temperature probe's 304 stainless sheath; in the saltwater version not even that sheath touches the flowing water — no metal at all, for a slightly slower temperature response.
没有金属冷板，水直接流过制冷片的陶瓷面，四周用耐水密封圈封住。铜、锌、铝离子对鱼虾有毒，所以水路上一点都没有。标准版水路里唯一的金属是测温探头的 304 不锈钢外壳；海水版连这个外壳都不接触水流，水路零金属，代价是温控响应略慢。
It sits inline on the canister filter's return, so nothing goes in the tank and no second pump is needed. The whole unit runs on 12 V.
串在过滤桶的出水管上：缸里不放东西，也不用再加一个水泵。整机 12 V 低压供电。
Its own changes are gentle: from 25 to 28 °C takes six hours, at 0.5 °C an hour. And it shields the tank from the room: a window opened on a cold night, the heating switched on, the sun on the glass — the water still changes no faster than 1 °C an hour, as far as its power allows. Both rates are adjustable.
它自己变温很慢：从 25 °C 改到 28 °C，按每小时 0.5 °C 走，六个小时到位。外面来的冲击它也拦着：冬夜开窗、暖气一开、太阳晒到缸上，水温每小时最多变 1 °C（在机器能力范围内）。两个速度都可以调。
When the water stops moving, it eases off the power so the water in the channel never gets too hot or icy, and picks up again when the flow returns.
水一停，它自动收小功率，水道里那点水不会被烫着、也不会结冰；来水后自动恢复。
Water outside the safe range, a sensor or a fault, weak flow — the light, the beeper and the app tell you. It even warns when a heat wave is more than one unit can carry, once it has been working flat out for two hours and the water is still a full degree short.
水温超出安全范围、传感器或设备故障、水流变弱，灯、蜂鸣器、App 一起提醒。热浪来了一台扛不住，它也会告诉你：全力工作两个小时、水温还差 1 °C 以上时提醒。
Linked units run as one: a lead unit decides, the others follow over a wireless link, and if the lead unit drops out another takes over within two minutes and keeps the tank where it was.
多台联动就像一台：一台做主，其余无线跟随；主机掉线，两分钟内另一台自动接管，缸温照样守住。
AquaComfort’s controller is the very board Frostflare runs on, and it is open: schematic, PCB and BOM are published on OSHWHub. One board, proven in one product, now drives two. OSHWHub →
安澜的控制器就是霜焰那块主板，而且是开源的：原理图、PCB 和 BOM 都公开在立创开源硬件平台。一块已经在霜焰上跑过的板子，两个产品通用。立创开源 →
The structure of the first prototype is done. Here is what is inside, and why it is built this way.
首版样机的结构设计已经完成。下面是它的里面，以及为什么这样做。
In and out are standard G3/8 female threads, marked IN and OUT on the base. Screw in the barb or quick connector for your hose size — plastic, never brass.
进出水口是通用的 3 分（G3/8）内丝，底座上标着 IN / OUT。拧上和你水管匹配的宝塔或快拧接头就行（用塑料接头，别用黄铜）。
The whole water path is one moulded plate: no joints to leak. The thermoelectric element's ceramic face sits right on the serpentine in the middle, pressed down at four corners onto the gasket.
整条水路是一块一体成型的板，没有拼接缝可漏。制冷片的陶瓷面直接压在中间的蛇形水道上，四角螺丝把它压紧在密封圈上。
The inlet and outlet open out in a teardrop so the water spreads smoothly before the four passes under the ceramic, each 6 × 14 mm. Low loss means the filter keeps its flow — and fast water under the ceramic means good heat transfer.
进出口做成渐扩的「水滴」形，水先平顺地展开，再走过陶瓷面下的 4 程蛇形水道（每程截面 6 × 14 mm）。压损小，过滤器的流量保得住；流速快，换热就好。
Structural CAD renders of the first prototype. Colours, finish and details will change before launch.
首版样机的结构设计渲染图，颜色、表面处理和细节上市前还会调整。
Most tanks do not need to sit at one exact number. Give AquaComfort a range and the water follows the room for free; the unit steps in only near the edges. Pick a mode to see what the water does.
大多数鱼缸并不需要钉死在一个温度。给它一个范围，水温跟着房间自由变化，快出界时它才出手。点一个模式，看看水温会怎么走。
One number, held to ±0.2 °C whatever the room does, as long as it is within the unit’s capacity. The unit works through every swing of the room, so this is the mode that costs the most.
设一个温度，室温怎么变，都守在 ±0.2 °C 以内（在机器能力范围内）。房间每一次冷热变化它都要出手，所以也是最耗电的模式。
Say 23–27 °C. Inside it the unit rests and the water follows the room for free — unless it starts changing too fast; near an edge it holds just inside. In spring and autumn that is 87 % less energy than Fixed.
比如 23–27 °C。范围内机器休息，水温跟着房间自由变化（变得太快时才出手），快到边缘时守在边缘内侧。春秋季比定温省电 87 %。
A target that moves with time. Five presets, every step editable in the App: Day & night (set only the coolest and the warmest; coolest at dawn, warmest in the afternoon, never a step), Seasons (a target per month, joined smoothly), Spawning (a cool “rainy season”, then back), New fish (from the bag’s temperature to the tank’s at 0.5 °C an hour) and Ich warming (up 1 °C a day to 30 °C, hold, back).
让目标温度随时间走。五个预置程序，步骤都能在 App 里改：昼夜（只设最凉和最暖两个温度，清晨最凉、午后最暖，从不突变）、季节模拟（按月给目标，平滑过渡）、繁殖诱导（模拟雨季降温再回升）、新鱼过缸（从运输袋的水温每小时 0.5 °C 走到缸温）、白点病升温（每天升 1 °C 到 30 °C、保持、再降回）。
Simulation: a 60 L open-top tank over two days of a spring room (20–28 °C); each curve is the water the control software actually produced in the loop.
仿真：60 L 开放式鱼缸，春秋季室温（20–28 °C）下的两天；曲线是控制程序在闭环里实际跑出来的水温。
Four situations it was designed around, and what to set in each.
它就是为这四种情况设计的，每种怎么设也写好了。
At 30 °C the tank follows the room, and warm water holds less oxygen.
房间 30 °C，缸水跟着到 30 °C，水越热溶氧越少，鱼浮头。
It keeps the tank cool without air-conditioning the room. The heat leaves through the fan.
不用为了鱼整天开空调。热量从风扇排走，不进水。
A heater has to be put in every autumn and taken out every spring.
南方冬天屋里十几度，每年秋天放加热棒、春天再拆。
The same unit heats, on less power than a heater. Nothing to swap when the season turns.
同一台直接加热，比加热棒省电，换季什么都不用动。
These need exact temperatures and slow, planned changes.
要的是准确的温度，和慢慢的、按计划的变化。
Fixed mode holds to ±0.2 °C; every change follows the rate limit, 1 °C an hour by default.
定温守在 ±0.2 °C；每次变温都按变温限速走，默认每小时 1 °C。
The most sensitive to heat — and to copper.
最怕热，也最怕铜。
A 20 L shrimp tank can sit about 10 °C below the room, and no copper touches the water; for a reef tank there is a saltwater version in which not even the 304 probe sheath touches the flowing water.
20 L 的虾缸能比室温低约 10 °C；水路无铜。珊瑚缸可选海水版，连 304 测温探头外壳都不接触水流。
It goes on the filter’s outlet: tank → filter → AquaComfort → back to the tank. For a big tank, split the return with a Y piece and put two units side by side (in parallel): the filter keeps far more of its flow than with the units in a row, and the tank holds its temperature just as well. Several units on a small filter go in a row instead (see the calculator below).
接在过滤器的出水口：鱼缸 → 过滤桶 → AquaComfort → 回鱼缸。大缸用一个 Y 型三通，把两台并排接（并联）：比串成一排，过滤器能保留多得多的流量，控温效果几乎一样。过滤器小、又要接好几台时，改成串联（见下面的计算器）。
Tell it about your tank and your room. It tells you how many units and how to plumb them — and what a year of it costs.
说说你的缸和房间，它直接告诉你要几台、怎么接，一年大概多少电。
Side effect of both: condensation and melted frost may drip from the heatsink onto whatever the unit stands on. The unit’s own key parts are waterproofed — decide by where it sits (a tray or a towel underneath, or keep the defaults).这两项的副作用：散热器上的冷凝水、化霜水可能滴到摆放机器的台面上。机器本身的关键部件做了防水，请根据摆放位置自行决定（垫个托盘或毛巾，或者保持默认）。
The region only sets how the year divides into warm and cold months; the coldest and hottest are the figures you entered above.地区只决定一年里冷热月份怎么分布；最冷、最热按你上面填的温度。
| Room室温 | Coolest制冷：最低到 | Warmest制热：最高到 |
|---|
Simulation, to be confirmed on the bench before launch. Open-top tank, lights on 10 h a day, 60 % humidity; the filter turns the tank over about 6 times an hour on its own (300–1500 L/h). Summer and winter are taken as steady rooms; the yearly figure takes the chosen region’s pattern of warm and cold months, stretched between your winter and summer figures, with the room swinging ±3 °C a day. A range costs about what holding its two edges costs.
仿真结果，上市前以实测为准。条件：敞口缸，每天开灯 10 小时，湿度 60 %；过滤器单独时每小时约循环 6 倍缸容积（300–1500 L/h）。夏天、冬天按恒定室温算；一年的用电按所选地区冷热月份的分布、缩放到你填的冬夏温度、每天 ±3 °C 波动来算；温度范围的耗电按守住两条边缘估算。

| Power供电 | 12 V DC adapter12 V 直流适配器 |
The whole unit runs on 12 V, and the water meets the element's ceramic face, the plastic channel and the 304 stainless probe sheath (in the saltwater version, not even that); the wiring stays on the dry side of the gasket.
整机 12 V 低压供电；水只接触制冷片的陶瓷面、塑料水道和 304 不锈钢探头外壳（海水版连探头外壳都不接触），导线和焊点都在密封圈的干侧。
Somewhat, as any inline device does. For a big tank, link units side by side (in parallel), which keeps most of the filter's flow.
会小一些，任何串在管路上的设备都会。大缸建议多台并联，过滤器的流量能保留大部分。
It eases off by itself so the water in its channel neither overheats nor freezes, tells you the flow is weak if it stays stopped, and carries on when the water moves again.
它自动收小功率，水道里的水不会过热也不会结冰；停得久了会提示「水流弱」；来水后自动继续工作。
The only moving part is the heatsink fan. Its speed follows the load, and when nothing needs doing it stops completely.
唯一会动的是散热风扇。转速跟着负载走，不需要工作的时候完全停转。
It starts again on its own and brings the tank back gently, at the same ramp rate as any other change.
来电自动恢复，并且按变温限速把水温慢慢带回来，不会猛拉。
Yes — choose the saltwater version: not even the 304 probe sheath touches the flowing water, so there is no metal in the water path. The reading lags by tens of seconds, so the temperature response is slightly slower; in simulation it holds the tank just as closely.
能，请选海水版：连 304 测温探头外壳都不接触水流，水路零金属。读数会慢几十秒，温控响应略慢；仿真中日常控温精度基本不受影响。
It keeps working flat out and the water settles as close as it can get. If it stays more than a degree short for two hours, you get a "not enough capacity" notice with what to do: add a unit, switch to Range mode, or shade and cover the tank. Use the calculator above to size it before you buy.
它会一直全力工作，水温尽量靠近设定。如果全力两个小时后还差 1 °C 以上，会提醒你「能力不足」，并告诉你怎么办：加一台、改成温度范围模式，或者给缸遮阳加盖。买之前可以先用上面的计算器算一算。
