A solar thermal stage inside the refrigerant circuit — not a solar panel wired to an air-conditioner. The distinction is the whole point, and it is where the saving comes from.
这是在制冷剂回路内部增加的太阳能热力环节，而不是把光伏板接到空调上。这一区别正是关键所在，节能也由此而来。
In any vapour-compression system, the compressor raises the refrigerant's pressure and temperature so that it can reject heat outdoors. Almost all of the electricity a cooling system consumes is spent on that one job.
在任何蒸气压缩系统中，压缩机的作用是提升制冷剂的压力与温度，使其能够在室外侧排热。制冷系统所消耗的电能，几乎全部用于这一件事。
Therm-Aire inserts an evacuated tube collector into the suction line, ahead of the compressor. Solar radiation and ambient heat superheat the refrigerant vapour before it is compressed. The compressor therefore begins its work from a higher pressure and temperature, and reaches the same discharge condition with less electrical input.
Therm-Aire 在压缩机之前的吸气管路上接入真空管集热器。太阳辐射与环境热能在压缩之前对制冷剂蒸气进行过热处理，压缩机因而从更高的压力与温度起步，以更少的电功输入达到相同的排气状态。
Nothing downstream changes. The condenser, the expansion device, the indoor units and the controls all remain conventional, which is why the system can be retrofitted to buildings already in service.
下游环节完全不变。冷凝器、节流装置、室内机与控制系统均维持常规配置——这也是该系统可以在既有建筑上加装改造的原因。
One added component, one added heat input, on an otherwise standard refrigeration loop.
在一个其余部分完全标准的制冷循环上，增加一个部件、引入一路热量。
Solar cooling is a crowded term. These approaches differ in what they capture, what they drive, and what has to change in the building.
"太阳能制冷"是一个含义混杂的说法。以下三条路径在"捕获什么、驱动什么、建筑需要改动什么"上截然不同。
| Dimension | Therm-Aire solar thermal | Photovoltaic-powered cooling | Absorption chiller |
|---|---|---|---|
| 维度 | Therm-Aire 太阳能热制冷 | 光伏供电制冷 | 吸收式制冷机 |
| What is captured | Solar radiation and ambient heat | Solar radiation converted to electricity | Solar or waste heat at higher temperature |
| What it acts on | The refrigerant itself, before compression | The building's electricity supply | A separate thermally driven cooling cycle |
| Indoor equipment | Unchanged — conventional indoor units | Unchanged | Chilled water distribution required |
| Typical scale | Split and packaged systems, per block or per unit | Whole-building electrical supply | Large central plant |
| Retrofit into an occupied building | Practical — the circuit is modified at the outdoor unit | Practical, subject to roof area and grid approval | Major works |
| Behaviour without sun | Reverts to conventional operation; ambient heat still contributes | Draws from grid or storage | Requires a backup heat source |
| 捕获什么 | 太阳辐射与环境热能 | 太阳辐射转换为电能 | 较高温度的太阳能热或工业废热 |
| 作用对象 | 制冷剂本身，且在压缩之前 | 建筑的电力供应侧 | 另设一套热驱动制冷循环 |
| 室内设备 | 不变，沿用常规室内机 | 不变 | 需要冷冻水输配系统 |
| 典型规模 | 分体式与单元式系统，按栋或按户配置 | 整栋建筑的电力供应 | 大型中央机房 |
| 在使用中的建筑加装 | 可行，改造集中在室外机侧的回路 | 可行，受屋面面积与并网审批限制 | 属于重大改造工程 |
| 无日照时的运行 | 回到常规运行方式，环境热能仍有贡献 | 取用市电或储能 | 需要备用热源 |
In the BCA Academy side-by-side test, a Therm-Aire system recorded 38.9 kW against 62.0 kW for a popular branded inverter system over a 4.5-day monitored period — a saving of 23.1 kW, or 37%.
在新加坡建设局学院 BCAA 的并行对比实验中，4.5 天监测周期内，Therm-Aire 系统实测 38.9 kW，对标主流品牌变频系统为 62.0 kW——降低 23.1 kW，节电 37%。
Published figures for the technology across installations range more widely than that, because the result on any given building is governed by four things:
该技术在不同项目上的公开数据区间比这一数字更宽，因为具体建筑的结果取决于以下四项：
The system operates conventionally. Ambient heat around the outdoor unit still contributes some superheat, but the large saving belongs to the sunlit hours. Any honest projection must weight the saving by your actual operating hours — ours does.
系统按常规方式运行。室外机周边的环境热能仍能提供一部分过热，但显著的节能属于有日照的时段。任何诚实的测算都必须按贵方实际运行时段加权——我们的测算即如此处理。
System cost has been reported at roughly 20% above a standard inverter installation, with the difference recovered from electricity savings in about two years. Tariffs and running hours move that number in both directions, so we quote it per building rather than as a headline.
公开报道口径为系统成本较标准变频方案高出约 20%，差额通常在两年左右由电费节省收回。电价与运行小时数会使该数字上下浮动，因此我们按建筑逐个测算，而不作统一宣称。
Mounted at the outdoor unit — on a roof, ledge or bracket. Sized to the compressor duty, not to the roof area available.
安装于室外机附近的屋面、挑檐或支架上。按压缩机工况选型，而非按可用屋面面积配置。
The heat exchange stage that ties the collector into the suction line, with isolation for service.
将集热器接入吸气管路的换热环节，并设置检修隔断。
Conventional outdoor unit, matched to the system. Existing units can be retained where condition allows.
常规室外机组，与系统匹配。状况允许时可保留既有机组。
Set-point control per zone, with metering so the saving can be verified against the baseline rather than asserted.
分区设定点控制，并配置计量，使节能量可对照基准进行核验，而非仅凭宣称。
Conventional systems lose capacity as ambient temperature rises — precisely when the building needs them most. Therm-Aire's thermal stage gains input under the same conditions, which is why the technology was deployed in Sudan in 2008 and has run there since.
环境温度升高时，常规系统的制冷能力反而下降——而这正是建筑最需要制冷的时刻。Therm-Aire 的热力环节在同样条件下获得的输入反而增加，这也是该技术于 2008 年在苏丹落地并持续运行至今的原因。
