第3圖一般地說明使用第1A及2A圖之系統組態及VSD 2〇 104的一致冷或冷卻系統的一實施例。如第3圖中所示,該 HVAC、致冷或液體冷卻系統300包括一壓縮機302、一冷凝 器配置304、一液體冷卻器或蒸發器配置306及該控制面板 308。該壓縮機302被由VSD 104提供電力的馬達106驅動。該 VSD 104自AC電源102接收具有一特定的固定線路電壓及固 10 1352183 定線路頻率的AC電力,且以所希望電壓及所希望頻率提供 AC電力給該馬達ι〇6,該等所希望電壓及所希望頻率可變^匕 以滿足特定的需求。該控制面板308可包括各種不同的元件, 諸如一類比至數位(A/D)轉換器、一微處理器、—非依電性記 5憶體和一介面板,用以控制該致冷系統300之操作。該控制面 板308還可被用以控制該VSD 1〇4及該馬達106之操作。
壓縮機302壓縮一致冷蒸氣且經由一排出管遞送該蒸 氣到該冷凝器304。該壓縮機302可以是任何適當類型的壓 縮機,例如,螺旋式壓縮機、離心式壓縮機、往復式壓縮 10機、滿旋式壓縮機等。由該壓縮機302遞送到該冷凝器304 的該致冷蒸氣進入與一流體(例如,空氣或水)的一熱交換關 係,且經歷一相變成為一致冷液體,作為與該流體的該熱 交換關係之結果。來自該冷凝器3 04的該已冷凝液態致冷劑 流經一膨脹(expansion)裝置(未顯示)到達該蒸發器3〇6。 1S 該蒸發器3〇6可包括用於一冷藏負載之一供水管線 (supply line)及一回水管線(return line)的連接。輔助 (secondary)液體(例如,水、乙烯、氣化鈣液或氯化鈉液) 經由回水管進入該蒸發器306並經由供水管離開該蒸發器 306。該蒸發器306中的液態致冷劑進入與該輔助液體的一 20 熱交換關係,以降低該輔助液體之溫度。該蒸發器306中的 該致冷液體經歷一相變成為一致冷蒸氣,作為與該輔助液 態的熱交換關係之結果。該蒸發器306中的該氣態致冷劑經 由一吸入管線(suction line)離開該蒸發器306並返回到該壓 縮機302,以完成該循環。要知道,倘若該冷凝器304及蒸 11 1352183 發器306中致冷劑可獲得適當的相變的話,任何適當組態的 冷凝器304及蒸發器3〇6可被用於該系統300中。
該HVAC、致冷或液體冷卻系統300可包括許多第3圖中 未顯示的其他特徵。為了說明,這些特徵已有意被省略以 5簡化圖式。此外’儘管第3圖以具有一個被連接在一單一致 冷電路中的壓縮機來說明該HVAC、致冷或液體冷卻系統 300,但要知道,該系統300可以具有多個被連接到一個或 多個致冷電路的每一個中的壓縮機,由一單一Vsd提供電 力(如第1B及2B圖中所示)或由多個VSD提供電力(一般地 10 見第1A及2A圖中所示之實施例)。 接下來參考第4圖,一VSD 104包括一個三相線路電抗 器402,經由保護裝置(諸如保險絲10或一斷路器)連接到該 AC電源102 ^該線路電抗器402賦能主動轉換器202之輸入 處的電流限制,且允許該已升壓之DC鏈結電壓之產生。一 15 輸出LC渡波器404連接到該換流器206之輸出,以滤波輸出 波形,且衰減電雜訊及與該換流器206之輸出波形相關聯之 諧波。該LC濾波器404與該換流器206及例如該馬達1〇6(例 如,見第1A圖)串聯。一個三相旁路接觸器400與該VSD 104 並聯’自該等保護裝置10之下游端到該LC濾波器404之輸 20 出。一主動轉換器202的使用提供了對該DC鏈結204處電壓 的快速主動控制。該主動轉換器202提供擴展的渡過 (ride-through)能力、在一通用輸入電壓上的操作能力,及 無關於該輸入線電壓大小而規劃該AC輸出電壓大小之能 力。使用該主動轉換器202,該DC鏈結204處的電壓精確且 12 1352183 迅速地被控制。從而,該VSD 104之輸出電壓也精確且迅速 地被控制。一電力濾波器404被連接在該VSD 1〇4之輸出, 以提供正弦輸出電壓到該馬達106。一#路接觸器働被併 入在該VSD 104之内,用以在該系統之全速操作時提供一電 5感器馬達106之直接、跨接線路操作。該整合旁路接觸器400 可被賦能及去能,若其適當地被應用到已裝配有一主動轉 換器202之該VSD 104的話。第4圖中所示之組態允許在 50/60HZ幹線操作或降低的頻率操作時,該VSD 1〇4的連續 操作,而當自VSD操作模式切換到跨接線路操作模式時, 10並不中斷該冷卻器馬逹106及壓縮機302之操作。用以精確 地控制該VSD輸出電壓、頻率及頻率的相位同步於該電 壓源102之輸入電壓、相位及頻率的能力提供跨接線路 (即,滿幹線電壓及頻率)操作及VSD控制操作之間雙向的電 氣負載之一平滑、通透的轉移。此平滑、通透負載轉移消 15除了超出該負載所要求的所需扭矩的扭矩偏移(torque excursion)。該平滑負載轉移能力消除了典型地與將電力供 應自VSD轉移到幹線相關聯之傳動系(driveline)震動。結 果,一大小縮小過的接觸器可被用以轉移負载,且湧入電 流被消除’而不管該VSD 104所處之操作模式。
20 全速操作的VSD 104之電力損失可藉由旁路該VSD 104而被降低或消除。與一習知的VSD相關聯之正常損失一 般範圍在2%到3%,且該等損失對於使用一主動轉換器202 的VSD來說範圍可高達4%到5%。用於為一HVAC冷卻系統 提供電力的具有整合旁路接觸器400之VSD 104的應用,在 13 1352183
真必須在一預定最小位準之内。該電壓失真要求需要一輸 出L-C濾波器404必須被整合到該VSD中’以移除來自vSD 輸出的大部分輸出電壓諧波。該VSD 104之控制方案也必需 整合如下兩個其他特徵:1)輸出電流限制控制及2)無感測器 5 (sensorless)扭矩控制。輸出電流限制控制被組配以限制感 測器處的可得輸出電流Ivsd在一預定限制。無感測器感應馬 達扭矩控制被組配以使用已感測參數Imtr及Vmtr來控制該 馬達扭矩。為了使該VSD 104能夠將輸出電壓以相位及頻率 二者鎖定到該AC輸入源102 ’該AC輸入源102或Vin必須被 10偵測。最後’該DC鏈結204處的電壓VDCL被偵測並被控 制在一預定電壓位準,以使該VSD 104能夠調整RMS馬達 電壓以匹配該VSD 104輸入處的電壓VIN。 該等系統控制通常在系統控制面板308中被實施。當該 控制面板308要求該冷卻系統壓縮機/馬達3〇2、1〇6操作在 15低於該AC電壓源頻率的一規定範圍内操作時,自vsd操作 到旁路接觸器操作的轉變發生。該範圍可藉由使用整合部 分負載值(IPLV)繪製(plot)未裝配VSD冷卻器之效率對已裝 配VSD冷卻器之效率來指定,在各種部分負載條件 下的效率量測之加權平均,如ARI標準55〇/59〇-98中所描述 2〇的,且其在此以參照方式被併入本文。該頻率範圍一般在 最大頻率之1.0Hz之内。例如,對於一6〇Hz的線路,當操作 在59.0Hz或向於59.0Hz時,藉由自該AC電壓源1〇2的直接操 作’更有效的操作被獲得。在一實施例中,轉至該旁路接 觸器400的轉變直到該冷卻系統操作於穩定狀態時才發 15 1352183 生,即,實際脫離冷卻水溫在一預定溫度帶之内,例如, 關於該脫離冷卻水溫設定點的正負約〇.2叩。 參考第5圖,對該VSD 104操作的控制被描述。在步驟 600,該控制面板決定用於旁路接觸器操作的上述準則被滿 5足。在步驟61〇,一控制信號自該控制面板3〇8被發送,用 以將該VSD 104之操作自VSD操作轉變到滿AC輸入電壓。 在步驟620,該VSD之輸出頻率被可控制地增加且相位被調 整,以精確地匹配該AC電壓源輸入幹線頻率及相位。在步 驟630,該DC鏈結電壓按所需要的被調整,以*RMS馬達 ίο電壓與RMS輸入幹線電壓相匹配。在步驟64〇,一電流限制 被賦能’且在步驟650 ’該旁路接觸器4〇〇被導通⑷〇se)。 在步驟660 ’用於該換流器206及該主動轉換器202的閘控信 號被去能。雖然該等換流器閘控信號已經被去能,但由於 該驅動機的該換流器部分206内所包含的反並聯式二極 15體,該VSD2DC鏈結電壓保持在近似等於輸入線間幹線電 壓峰值之位準上。該等反並聯式二極體之操作在共同擁有 的美國專利第7,005,829號中詳細地被提出,其全部在此以 參照方式被併入本文。由於該換流器2〇6及主動轉換器2〇2 閘控信號被去能,該VSD 104中所消耗的功率實質上變成 2〇零。在步驟670,馬達保護裝置(例如,馬達超載電流感測 等)此時使用該IMTR參數而被執行,且若需要的話,馬達切 斷裝置將藉由脫離該旁路接觸器4〇〇而被實施。剛才所描述 的轉變方法消除了馬達RMS電壓或馬達RMS電流中的階躍 變化,這接著消除了由此等階躍變化所導致的所有扭矩暫 16 1352183 態及馬達湧入電流。 相反的操作在第6圖中被提出》自幹線操作返回到vsd 操作的轉變應該僅當該等系統控制要求該冷卻系統壓縮機 /馬達操作在低於該AC輸入源102之頻率的一規定範圍之内 5的一頻率上時發生。在一實施例中,該規定範圍藉由使用 該1PLV負載線繪製未裝配VSD壓縮機3〇2之效率對已裝配 VSD壓縮機302之效率而決定。該頻率範圍一般低於最大頻 率之1.0Hz。當被命令操作在59.0Hz或低於59〇出時,藉由 經由該VSD 1〇4的操作,該冷卻系統之更有效的操作被獲 10得。在一實施例中’自旁路接觸器400到VSD 104的轉變可 僅當該冷卻系統操作於穩定狀態操作時發生,即實際脫離 冷卻水溫在接近該脫離冷卻水溫設定點的一預定範圍(華 氏+/-0.2度)之内。 在步騾700,將該壓縮機/馬達頻率,mtr與該AC輸入源 15 1〇2之頻率厶c ΙΝΡυτ相比較,且若差值大於1.〇,則在步驟 705,該控制面板發送一命令信號,以開始自該AC輸入源 之滿電壓到VSD操作之轉變。該轉變程序開始於步驟71〇, 如下。在步驟710,該主動轉換器2〇2被賦能,且Vdclink被 控制到其標稱設定點。在步驟72〇,輸出頻率被設定到該AC 20輸入源102之已感測輸入頻率,且輸出電壓VMTR之相位被設 定到該AC輸入源102之相位。在步驟73〇,該¥8£) 1〇4之電 流限制被賦能,且該電流限制位準被設定等於參數丨mtr之電 流位準。在步驟740,該等換流器閘被賦能,且該DC鏈結 電壓被細緻地調諧,直到VSD電流及馬達電流之間的差 17 (即’參數(Ivsd-Imtr))被最小化。在步薄750,該控制系統決 定該參數(Ivsd-Imtr)是否在一規定限制之内。若是,則在步 驟760,旁路接觸器400被不導通(open),且該VSD 1〇4為該 馬達負載提供電力。否則’該控制系統返回監視該差值 5 (Ivsd_Imtr) 0 儘管在圖中被說明且在此被描述的該等示範性實施例 目前是較佳的,但應該知道,此等實施例僅以範例的方式 被提供。因此,本申請案並不被限制在特定實施例中,而 擴展到仍然落在附加申請專利範圍之範圍中的各種修改。 10任何程序或方法步驟的順序或次序可依據可選擇的實施例 被變化或重排序。 重要的疋要主思,可變速度驅動機及方法的構成及配 置(如在各種示範性實施例中所顯示的)僅是說明性的。雖然 僅一些實施例已被詳細描述於此揭露中,但檢閱此揭露的 15該技藝中具有通常知識者將立即瞭解,許多修改是可能的 (例如各種實施例的大小、尺度、結構、形狀及比例,參數 值、安裝配置、材料使用、顏色、方位等之變化),而本質 上並不脫離申請專利範圍中所敍述之標的的新穎教示及優 勢。例如’如整體被形成後所示之元件可由多個部分或元 20件構成’元件之方位可被反向或被變化,且離散元件的種 類或數目或者方位可被改變或變化。因此,所有這些修改 企圖被包括在本申請案之範圍内。任何程序或方法步驟的 順序或次序可依據可選擇的實施例被變化或重排序。在申 。月專利範圍中’任何手段功能(瓜⑽如pius functi〇n)用語企 18
