What if you could combine the zoning flexibility of VRF with the safety and simplicity of water based systems all in one design?

如果你能將VRF的區域控制彈性，與水系統的安全和簡潔，全部整合在一個設計裡呢？

That's exactly what the new generation of hybrid VRF systems promises.

這正是新一代的混合VRF系統所承諾的。

It looks familiar from the outside, but what's happening inside is completely different.

從外面看，它看起來很熟悉，但裡面發生的事情卻完全不同。

In this video we'll break down how this technology works, why it's changing the way we think about H Vac design, and

在這支影片裡，我們將深入解析這項技術如何運作，為何它正在改變我們對HVAC設計的看法，以及

The Outdoor Unit the outdoor unit in a hybrid VRF system works just like a traditional VRF heat pump.

室外機 混合VRF系統中的室外機，運作方式就像傳統的VRF熱泵一樣。

It's the heart of the system where heating or cooling is generated.

它是系統的核心，負責產生加熱或冷卻。

The unit uses refrigerant to absorb or release heat to the outside air depending on the season.

視季節而定，該單元利用冷媒吸收或釋放熱量到外部空氣中。

Hybrid Branch Controller the hybrid branch controller is the key component that makes a hybrid VRF system different.

混合分歧控制器 混合分歧控制器是讓混合VRF系統與眾不同的關鍵組件。

It acts as the bridge between the refrigerant and the water loops inside the controller.

它充當控制器內部的冷媒與水路之間的橋樑。

The refrigerant transfers its heating or cooling energy into water which is then circulated to the indoor units.

冷媒將其加熱或冷卻的能量轉移到水中，然後將水循環到室內機。

This setup keeps refrigerant contained to the mechanical area and uses only water inside the occupied spaces, making the system safer, easier to install and more flexible for zoning.

這種設置將冷媒限制在機房區域內，並僅在使用者空間內使用水，使系統更安全、更易於安裝，並為分區提供更大的靈活性。

The hybrid controller contains two small pumps to serve the hot and cold water loops.

混合控制器包含兩個小型泵，用於服務熱水和冷水路。

Refrigerant Piping Refrigerant piping connects the outdoor unit with the hybrid branch controller, using only two pipes such as in a typical split system heat pump.

冷媒配管 混合分歧控制器與室外機連接的冷媒配管，僅使用兩根管子，就像傳統的分離式熱泵一樣。

This is the only refrigerant piping required for this system, so the amount of refrigerant is limited to the distance between the outdoor unit and the indoor hybrid branch controller.

這是此係統所需的唯一冷媒配管，是以冷媒量僅限於室外機與室內混合分歧控制器之間的距離。

There are various rules for the allowable distances, but

should be fine for most applications as we're talking hundreds of feet.

對於大多數應用來說應該是可以的，因為我們談論的是數百英尺。

Indoor Fan Coil Units There are several options for indoor units such as the ceiling cassettes, wall mounted fan coils and concealed ducted fan coil units.

室內風機盤管機組 室內機有幾種選擇，例如嵌入式天花機、牆掛式風機盤管和隱藏式風管風機盤管。

Water Piping in each zone, water hot or chilled is delivered, enabling heating or cooling in each indoor unit without refrigerant piping in that zone.

每個區域的水管配管，無論是熱水或冷水，都會被輸送到每個室內機，從而實現加熱或冷卻，而無需在該區域進行冷媒配管。

Water piping is run between the hybrid branch controller and the indoor fan coil units.

水管會從混合分歧控制器接到室內風機盤管機組。

The piping can be run in copper or polyethylene as indicated by the manufacturer.

依製造商訓示，這些管路可使用銅管或聚乙烯管。

This effectively replaces the refrigerant piping portion to indoor units with water piping, thus making indoor spaces refrigerant.

這有效地將連接到室內機的冷媒配管換成了水管，讓室內空間不需冷媒。

Many of the safety, regulatory and leak detection challenges associated with refrigerants in occupied areas are reduced.

使用空間內與冷媒相關的許多安全、法規和洩漏偵測挑戰都減少了。

Another advantage is that only two pipes need to be run between the branch controller and the fan coil instead of the four pipes run in a chilled water and heating hot water four pipe system.

另一個優點是，從分歧控制器到風機盤管只需要兩條管線，而不是傳統冷熱水系統的四條管線。

Because the HBC supports simultaneous heating and cooling, heat recovered from cooling zones can offset heating in other zones, just as in advanced VRF systems.

因為混合VRF系統支援同時加熱和冷卻，所以從冷卻區域回收的熱能可以抵銷其他區域的加熱需求，這跟先進的VRF系統一樣。

In effect, hybrid VRF combines the zoned flexibility of VRF with the safety, piping ease and hydronic advantages of conventional chiller boiler systems.

實際上，混合VRF結合了VRF的區域獨立控制彈性，以及傳統冰水機鍋爐系統的安全、配管便利性和水路優勢。

Next, you'll need the main water supply to the branch controller with a strainer, shutoff valve and prv.

接下來，您需要將主水供應接到分歧控制器，並裝設過濾器、截斷閥和壓力調整閥。

Since this is a hybrid system where water is heated, an expansion tank will be required to be attached to a port on the controller.

由於這是混合系統，需要加熱水，是以必須在控制器上的一個接頭安裝膨脹水箱。

The size of the expansion tank will need to match the amount of water contained in the system.

膨脹水箱的尺寸需要與系統內的水量相符。

The expansion tank needs to be at the same height or above the hybrid branch controller.

膨脹水箱需要與混合分歧控制器位在相同高度或更高。

Electrical the hybrid branch controller will need 208,230 voltage for power.

混合分歧控制器需要 208 或 230 電壓供電。

Of course, power is also required at the outdoor unit and each of the fan coils.

當然，室外機和各個風機盤管也需要電力。

Multiple Zones the hybrid branch controller allows you to connect to three fan coils on a single port.

混合分歧控制器允許您透過單一連接埠連接三個風機盤管，以實現多區域控制。

With some exceptions, this would require that all the zones have a similar thermal profile as only one mode of operation is allowed for the connected group.

除了少數例外，這意味著所有區域都必須有相似的熱傳特性，因為連接群組僅允許一種運作模式。

All connected zones must either be in heating or cooling mode together as there is only one set of pipes that can carry either hot or cold water.

所有連接的區域必須同時處於加熱或冷卻模式，因為只有一組水管可以輸送熱水或冷水。

Drain Lines the hybrid branch controller requires a drain as do all of the fan coils.

混合分歧控制器需要排水，所有風機盤管也一樣。

Often wall mounted fan coils require an internal condensate pump to lift the condensate into the attic space where it can pitch by gravity to the main drain.

牆掛式風機盤管通常需要內建的冷凝水泵，將冷凝水抽到閣樓空間，再靠重力排入主排水管。

Line Controls the control wiring is like the standard VRF system.

線控部分，其控制線路與標準VRF系統相同。

Each remote controller or thermostat is connected to their respective fan coil and then each fan coil is daisy chained together all the way back to the hybrid branch controller.

每個遙控器或恆溫器都連接到各自的風機盤管，然後各風機盤管再串聯連接回混合分歧控制器。

The branch controller is then wired to the outdoor unit.

分歧控制器接著會連接到室外機。

This allows the outdoor unit to discover all the connected components.

這樣室外機就能偵測到所有連接的組件。

If the occupant wants a remote controller that oversees the system from a convenient location, then a main controller can be mounted in the building facility's office and wired back to the outdoor unit.

如果使用者希望有個遙控器能從方便的位置監控整個系統，那麼可以在大樓設施的辦公室安裝一個主控制器，並將其線路連接回室外機。
