Which refrigerant can offer the biggest opportunity for reduction of carbon footprints?哪種冷媒給我們最大機會降低碳足印？

p20

We came across a good question from one of the students after completion of a four-day Carbon Auditor Professional (CAP) Course, organised by Hong Kong Association of Energy Engineers (HKAEE):

“After the CAP Course, I found out from the course manual that the GWP of HFC 134a is 1,300, while for R123, NO GWP figure is shown. Can someone tell me what the GWP of R123 is?

“If the GWP of R123 is as low as R152a – 140, or even lower, then will R123 reduce the emission of the CO2 equivalent by almost 90% as compared to R134a, if both leak the same amount?”

To answer this question, we would like to make use of the self-explanatory table below to show the solid environmental parameters for the common refrigerants in HVAC (see figure 1).

The GWP of R123 is 76 vs 1320 of R134a, which is 17.3 times different; in addition, R123 at one atmospheric pressure and 25°C is in liquid state and the density is 340 times higher than R134a. This is the reason why the leakage rate of R123 is smaller than that of R134a, and hence, according to LEED recognition3, the leakage rate is 0.5% per year, which is 4 times less than all other high-pressure refrigerants. Furthermore, the Practical ODP (actual measured ODP values at Troposphere in 2004) of R123 is 0.000364, slightly lower than the R134a value of 0.00039 after 20 years of application in worldwide industry.

One more important point is that the calculated LCCP (Life Cycle Climate Performance) of R123 would be the smallest among all commonly used refrigerant in terms of Kg·CO2 equivalent (carbon footprint), which is 13% less than R134a under the same tonnage of water cooled chiller.

Figure 1 : Refrgierant Properties 圖1：冷媒特性

In conclusion, if one solely focuses on the ODP, R134a would be a more environmentally friendly refrigerant, but if one takes a more comprehensive outlook, R123 would be the most superior refrigerant.

Which one is more environmentally friendly?

It all depends on whether you are willing to take a wider view.

More R123 Chillers in Hong KongIn fact, many of the owners of buildings in Hong Kong have already realised, or even experienced, the advantages that R123 refrigerant chillers have brought to both their buildings and the environment. Some of the projects in Hong Kong that use R123 refrigerant chillers include HKUST (still taking a comprehensive outlook of refrigerants after using more than 17 years of R123 chillers), Cityplaza 1 and 4, JW Marriott Hotel and Festival Walk, etc. The more attractive features of the R123 chiller can be found in the ‘Three Low and One High’ (see figure 2) and COP performance (see figure 3).

Advice from an ExpertOne of our industry’s well-known magazines, Japan Air Conditioning Refrigerant Newsletter (JARN)5, recently had an interview with an expert from the EPA in the US, Dr. Stephen Andersen, during which Dr. Andersen’s views were sought on why R123 is still being used in the market, despite its phase-out schedule.

The response of Dr. Andersen is very inspiring and is summarised below:i) It is not guaranteed that R134a will not be phased out

before R123.ii) We should continue to use R123 until a better

refrigerant is developed.

“As commented by the professional institutions and other respondents, equipment using HCFC-123 would be the last to be phased out due to the very low ozone depleting and global warming potentials but high cooling performance.”(see figure 4 and 5) 7

Wrap-UpWhile it can be definitively stated without objection that the largest single contributor to energy consumption in commercial buildings is “Chiller Power”, the R123 refrigerant chiller can offer us the biggest opportunity to reduce Hong Kong’s carbon footprint.

In view of strong demand of environmental protection, should we stop awhile to reassess our perception of the definition of ‘Environmentally Friendly Refrigerants’ ?

iii) There is no worry about the availability of R123, even if its phase-out remains on schedule.

iv) We should not rule out the possibility that R123 may be exempt from the phase-out because of its low GWP and high COP properties.

由香港能源工程師學會舉辦，在為期四天的「碳審計員專業（CAP）課程」結束後，一名學生提出了很有意思的問題：

「修讀CAP課程後，我發現課程手冊上寫著HFC 134a的GWP是1,300，但對於R123，卻沒有列出任何 GWP數據。請問R123的GWP是多少？」

「假如R123的GWP跟R152a一樣低至 140，甚至更低；那麼，假設R123與R134a洩漏同等份量，則R123所減少排放的CO

2當量，會否較R134a高出近90%？」

為解答上述問題，現利用下列簡明圖表，說明暖通空調中一般冷媒的實質環境參數（見圖1）。

R123的GWP為76，而R134a為1320，兩者相差17.3倍；此外，R123在一個大氣壓力及25°C下為液體狀態，密度亦較R134a高出340倍。這正是R123的洩漏率較R134a為小的原因；亦由於此，按照LEED認可標準 3，其洩漏率為每年0.5%，較其他高壓冷媒少4倍。另外，全球業界應用了這些冷媒20年後，R123的實際ODP（臭氧層消耗潛力）數值（即於2004年在對流層實際錄得的ODP數值）為0.000364， 較R134a的數值0.00039稍低。

另一重點是，R123的經計算LCCP（生命週期氣候影響），就Kg·CO2 當量而言（碳足印），是所有常用冷媒中最小的一個；在相同冷噸的水冷冷水機組下，其數值較R134a少13%。

總括而言，假如只著眼於ODP，則R134a是較環保的冷媒；然而，如全面一點去看，R123便是最卓越的環保冷媒。

哪一個較為環保？

這視乎你是否採用全面的角度。

R123冷水機組在香港日漸普及事實上，香港許多大廈業主已意識或甚至體驗到，R123冷媒冷水機組能為其大廈與環境帶來種種好處。香港部分項目現正採用R123冷媒冷水機組，例如香港科技大學（該大學在使用R123冷水機組逾17年後，仍然以全面的角度看待冷媒）、太古城中心1及4期、香港萬豪酒店及又一城商

場等。此外，R123冷水機組還有很多吸引的地方。總括而言，就是「三低一高」（見圖2）及性能系數表現（見圖3）。

專家意見我 們 業 內 的 一 份 著 名 刊 物《Japan Air Conditioning Refrigerant Newsletter（JARN）》5， 近 日 訪 問 了 美 國 環境保護署專家Dr. Stephen Andersen；其中記者曾向Dr. Andersen提問，指R123儘管已被安排逐步淘汰，為何市場上仍然有人採用。

Dr. Andersen的答覆甚富啟發性，現摘要如下：i) 現時尚沒有保證，R134a不會較R123先一步被淘汰。ii) 我們應繼續使用R123，直至有人研發出更優良及環保

的冷媒。iii) 即使R123已逐步減少生產，我們也毋須擔心其供應。iv) 我們不應排除R123會因其低GWP及高COP特性而獲

得豁免這個可能性。

Dr.StephenAndersen個人簡介：職位：策略氣候計劃總監機構：美國環境保護署

就HCFC冷媒而言，香港環保署於2008年10月向相關協會與公司發出信件，宣稱：

「根據專業機構及其他回覆者的意見，採用HCFC-123的設備將會是最後被淘汰，原因是它對臭氧層的消耗以及其全球暖化潛力均極低，並具有甚高的冷凍表現」。

（見圖4及5）7

總結毋庸置疑，在商業樓宇的能源耗用中，最大的單一來源就是「冷水機組的電力」。正因如此，R123冷媒冷水機組最有潛力，能大大減少香港的碳足印。

面對全球對環保的強烈訴求，我們應否停一停，重新審視我們對何謂「環保冷媒」的概念？

From Energy Efficiency to Green Building 從能源效益到綠色建築物

Following the discussion in the November 2007 issue about the revision of building energy codes (BECs) by EMSD, a Public Consultation on the Mandatory Implementation of Building Energy Codes (MBECs)1 was jointly launched by the Environment Bureau and EMSD in response to, mainly, the goal “to reduce energy intensity by at least 25% by 2030” set at the Asia-Pacific Economic Cooperation (APEC) Leaders’ Declaration on Climate Change, Energy Security and Clean Development in September 2007 as well as the 2007–08 Policy Address, “consult the public on the proposed mandatory implementation of the Building Energy Codes by means of legislation.” The consolidated views and comments were submitted to the Legislative Council Panel on Environmental Affairs last May for discussion. It is planned to introduce the legislative proposal to the Legislative Council within this year. What a long process, but Hong Kong is going to have her own building energy efficiency laws eventually!

MBECs will serve the purpose of setting a minimum energy efficiency, like ASHRAE Standard 90.1 and GB 50189 discussed in the previous issue mentioned above. Although we are forced to comply with the regulatory requirement, MBECs will play an important role in “market transformation” towards green building.2

Market transformation involves the development and implementation of a regulatory “push” through the establishment of mandatory minimum performance standards and a complementary “pull” from market-based mechanisms. The first stage of market transformation is the establishment of a regulatory framework of mandatory codes and standards.

In a mature building market like the U.S., it is expected that no more than 25% are pursuing green buildings, while the majority simply meet the minimum regulatory

requirements (see Fig. 1). Owing to the more stringent requirements of green building, the top building projects usually exceed the minimum energy efficiency set by the ASHRAE 90.1. This is obviously not driven by the regulation. In the U.S., for instance, state governments not only enforce building energy codes but also provide incentives for achieving higher performance standards, such as Energy Star and/or LEED (Leadership in Energy and Environmental Design, by the U.S. Green Building Council). In Hong Kong, the government has just launched “Building Energy Efficiency Funding Schemes.”3

A report to California’s Sustainable Building Task Force confirmed that minimal increases in upfront costs of about 2% to support green design would, on average, result in life cycle savings of 20% of total construction costs – more than ten times the initial investment.4 The “life cycle” concept is a fundamental difference as compared to conventional practice, which has been mostly focused on initial investment, not just from the standpoint of building construction cost, but from the environmental standpoint as well, because this “new” concept is more responsible both for the environment and for our next generations! If we are aware of the impact of building on the environment, we should have made such a paradigm shift much earlier, but now climate change is a wake up call.

In fact, EMSD launched an energy efficient building scheme more than ten years ago,5 and we have had a green building rating system – “HK-BEAM” (HK Building Environmental Assessment Method) – since 1996.6 Why up untill now have we become more enthusiastic about green building, or is it because of the appeal of LEED? I won’t say simply because of LEED, but it is true that a lot of building owners pursue green building due to the successful branding of LEED. A few success factors are given below from my personal observation.

- Transparency: project/certification information available from website

- Education: LEED-AP exams, local chapters, numerous workshops, seminars and GreenBuild…

- A good balance between simplicity and scientific in nature

- Credit point system: measurable targets, industry consensus, easy to use• plus Credit Interpretation Ruling (CIR) to provide

flexibility to exceptional cases or something not yet covered by the existing rating system

- Market transformation

In 2008, building market research revealed that high performance buildings (including LEED and Energy Star) enjoy a 2.5% higher occupancy rate, 8% higher rental rate, and as much as 30% higher sales price.7 (see Fig. 2) Obviously, this is appealing news to all building owners and developers, though I am not sure if this will be true for the building market in Hong Kong. What can be assured is that, besides energy and environmental factors, the green building design also strives to improve the indoor environmental quality so as to increase the productivity of workers in the building. Ideally, it helps the community by careful selection of the building construction site such that (1) building users can have good access to existing

basic services like banks, schools, medical centres and supermarkets, etc.; (2) it encourages alternative transportation to ease the strain on local infrastructure and/or to reduce pollution; and (3) it may even rehabilitate some damaged or contaminated sites.

One of the known problems in new building construction is the disconnection of building operation from the design, resulting in building performance often being unsatisfactory. For LEED projects, it is a mandatory requirement to involve the Commissioning Authority from the design stage.8 The individual serving in this role should be independent of the project’s design and construction management, which is to make sure that at least the energy related systems (e.g. HVAC) are installed, calibrated and perform according to the owner’s requirements documented throughout the design and construction stages.

As a conclusion, I think green building rating system is a tool to help us sustain building performance. Its success will really depend on how we use the tool, not on how good the tool is. If you can sense the market trend, there are new opportunities generated for building owners/developers, architects and design engineers as well as equipment and system providers. It’s exciting!

2007年11月號曾探討過機電工程署修訂『建築物能源效益守則』（BECs），繼後為回應2007年9月《亞太經合組織領導人關於氣候變化、能源安全和清潔發展的宣言》中訂下

「於2030年前把能耗強度至少降低25%」的目標，以及在2007-08年度的施政報告所述「就立法強制建築物能源效益守則的建議諮詢公眾」，環境局聯同機電工程署就強制實施

「建築物能源效益守則」（MBECs）1 的建議展開公眾諮詢。綜合的觀點及意見已於去年五月提交立法會環璄事務委員會討論，而立法建議預期將於本年內提交立法會。經歷過程真的漫長，但香港終於會有自己的建築物能源效益法。

MBECs旨 在 訂 下 最 低 能 源 效 益 的 指 標， 如ASHRAE Standard 90.1及國家標準GB 50189的規定，在上述的11月號中已討論過。雖然是強制性要遵守，但是MBECs在邁向綠色建築的「市場轉型」過程中擔當重要角色。2

市場轉型有賴憲制的「推動」– 強制實施最低效能標準

–以及市場機制的「拉動」，互相配合。而市場轉型的第一步往往是建立強制性法規和標準的憲制框架。

在成熟的物業市場如美國，不超過25%是追求綠色建築的，而大部分樓宇只符合規例的最低要求。（見圖1）由於綠色建築的要求較嚴格，頂尖的物業項目通常都超逾ASHRAE 90.1規定的最低能源效益標準。此現象顯然並非法規所驅使。在美國，州政府不單只勵行建築物能源守則，同時亦激勵發展商達致更高的效能標準，如能源之星、LEED（美國

綠色建築委員會設立的綠色建築環保節能設計標準）。在香港，政府剛推出了「建築物能源效益資助計劃」3。

一份加州可持續建築專責委員會的報告確認: 只要增加初投資約2%以支持綠色設計可為生命週期總建造成本節省平均20% – 即初投資的十倍以上。4 這「生命週期」的概念跟傳統的建造慣例有根本性的差異。傳統的概念著重首次投入的資金，而「生命週期」不僅考慮樓宇的建造成本，還會考慮對環境造成的影響，這是一個對環境及我們的下一代更負責任的「新」概念！倘人人都關注建築物對環境的影響，

我們應該更早開始，作出既有觀念的改變，現在氣候變化正好給我們一個當頭棒喝。

事實上，機電工程署在十多年以前就已推出「建築物能源效益註冊計劃」，5 還有1996年開始的一套綠色建築評級–

「HK-BEAM」（香港建築物環保評審法）6。為何至今才關注綠色建築呢？是由於LEED的動力嗎？雖然我不認為純粹是LEED的關係，但的確很多業主都會因為LEED的品牌效應而追求綠色建築。以下是我個人觀察到的幾個成功因素。- 透明度高：項目、認證的資料可從網頁查閱- 宣教：LEED-AP考試、成立分部、眾多工作坊、研討會

及GreenBuild大會 ……- 簡潔與科學化之間取得良好的平衡- 評分系統：可量度的目標、業界共識、使用簡便

• 加上評分上訴機制（CIR）可讓特別的情況或評級系統仍未涵蓋的情況可以靈活處理

- 成功的市場轉型

在2008年，物業市場研究指出高效能的建築物（包括LEED及能源之星）享有2.5%較高的佔用率，8%較高的租金及高達30%較好的售價。7（見圖2）這對所有業主及發展商來說顯然振奮的消息。雖然我不肯定香港物業市場的反應是否一樣，可以肯定的是，除了節能及環保因素之外，綠色建築物的設計亦著重改善室內環境的質素，以提昇樓宇內員工的生產力。更理想的是，綠色建築物的設計有助改善社區環境，因為發展商必須謹慎地為建造工地選址，以期

（1）可以方便樓宇的用家使用現有的基本設施如銀行、學校、醫療中心及超級市場等等；（2）鼓勵使用多種運輸方法以舒緩區內基建的壓力、減少環境污染；及（3）甚至復原已受損害或受污染的土地。

新建樓宇項目的一個通病就是建築物的營運往往與設計脫節，使建築物的效能表現欠佳。LEED 的項目在設計階段時已強制要求營運調試專員參與。8 擔當此角色的人士應獨立於項目設計及建造管理，以確保能源相關的系統（如暖通空調）按照業主的要求安裝、校正及運作，而這些要求從設計到建造階段中不斷的產生。

總括而言，綠色建築物評級系統是協助我們保持樓宇效能的工具。成功與否，視乎我們如何運用，而不在乎工具有多好。假如您已感受到這市場趨勢，就能發現它給業主/發展商、建築師及設計工程師以至設備和系統供應商都創出許多新機遇。這是多麼令人振奮呀！

Trane Dealer Trip 2009 - Xiamen特靈經銷商2009廈門之旅

The Trane Dealer Trip 2009 was successfully held in late February, with Xiamen, dubbed the most hygienic city in China, being this year’s destination. Bestowed the Habitat Scroll of Honour Award by the United Nations, Xiamen ranks fourth among the world’s best cities for living, thanks to its picturesque landscape and balmy weather as well as its proximity to Fujian Tulou, the historic earth buildings that entered the UNESCO’s World Heritage List last July.

To cater for the varied needs of the tour members, the dealer trip was separated into two groups, namely the golf group and the sightseeing group. The former mainly enjoyed golfing at the scenic courses in Xiamen, while different prizes were offered each day to recognize outstanding players.

On the other hand, the sightseeing group headed to Fujian Tulou to marvel at the ingenious, centuries-old architecture. Aside from Tianluokeng Tulou Group, the itinerary also included Chengqi Lou, Zhencheng Lou, Fuyu Lou, Rusheng Lou and Kuiju Lou. Besides, the group also visited Longkong Cave in Yongding County of Fujian; all were amazed by the grotesque stalactites and huge caverns formed by nature.

On the last night, both groups met in Xiamen for a sumptuous dinner, sharing with each other the happy moments of the past few days. Then next day, before flying home, all tour members went on an excursion to Gulangyu Island, where they visited a piano museum and feasted their eyes on the Victorian-style buildings, ending the five-day vacation on a perfect note.

2009年度經銷商之旅已於二月下旬舉行，今年的目的地，是被選為中國最清潔城市的廈門。當地獲聯合國授予「聯合國人居獎」，位居全世界最適合人類居住的城市第四位，不

但風景秀麗，氣候溫和，更鄰近剛於去年七月被聯合國教科文組織列入世界文化遺產名錄的「福建土樓」。

為配合不同團友的需要，是次經銷商之旅分為兩團 ─ 高爾夫球團及觀光團。高爾夫球團的團友主要在廈門環境優美的球場參與高爾夫球活動。為提高趣味，每日活動更設有不同獎項，以獎勵在球場上表現出眾的團友。

觀光團的團友則前往福建土樓參觀，欣賞這個歷史悠久而富有特色的古舊建築。行程期間除了參觀田螺坑土樓群外，還包括承啟樓、振成樓、富裕樓、如升樓、奎聚樓等等。此外，觀光團團友還參觀了位於福建永定的龍崆洞。外型奇特的鐘乳石及偌大的地下岩洞，使參觀者無不驚嘆大自然的鬼斧神工及奇妙。

兩團的團友最後一晚在廈門相聚，共晉晚餐，分享過去數天的愉快經歷。在行程結束前，全部團友更一起暢遊鼓浪嶼，參觀當地的鋼琴博物館，並欣賞其他維多利亞時代風格的歐洲式建築物，結束五天愉快的旅程。

Annual Dinner週年春茗This year’s Annual Dinner was held on 15 January and was attended by over 200 employees. On that night, Director and General Manager Mr K. K. Leung reported that the company had recorded encouraging performance despite the financial tsunami hitting the economy hard in the second half of last year. Citing the fact that Hong Kong had managed to ride out the Asian Financial Crisis and the SARS outbreak, Leung urged the staff to remain united and resolve current problems with confidence. Though 2009 is expected to be a challenging year, we can still outperform competitorsas by working proactively.

今年的公司週年春茗已於1月15日舉行，逾二百多名員工出席。在晚宴中，董事總經理梁基強先生表示，世界經濟去年下半年雖受金融海嘯影響，但公司整體表現仍錄得令人鼓舞的成績，實在值得高興。梁先生還勉勵員工，過去十多年香港經歷金融風暴及沙士的危機都能安然渡過；故此，只要我們齊心合力，當前的困難定能解決。展望2009年雖然是充滿挑戰的一年，但只要我們能比對手跑先一步，就能夠處於一個有利位置及戰勝對手。

Energy Management Training能源管理培訓Energy management in bui ldings has gained significance in the engineering sector in recent years. In light of this, Trane held an “Energy Management Opportunities in Buildings” training programme in early March for its 30-plus managers and engineers. Dr Sam Hui of the Department of Mechanical Engineering at HKU was invited to be the lecturer and explain the latest knowledge. The aim of the programme was to enhance the staff’s understanding and promote energy management in buildings, an issue that is crucial to environmental protection.

建築物能源管理近年成為工程界一個重要議題，有見及此，特靈於3月初為屬下三十多名管理及工程人員舉辦了一個“建築物能源管理機會”培訓課程，並邀請了香港大學機械工程學系講師許俊民博士為課程之導師，詳細講解有關能源管理的嶄新知識，以加強員工這方面的認識，及推動建築物能源管理這個對環境保護影響非常大的重要課題。

Centrifugal Type Compressor離心式壓縮機

Impeller in centrifugal type compressor離心式壓縮機的葉輪

Many types of compressors are used in central air condit ioning systems. The most common is the centrifugal type compressor, because it possesses a large cooling capacity, reliable performance and can be repaired on-site.

Centrifugal type compressors can be categorised into two kinds, namely the direct-drive type and the gear-drive type. The two different types of compressor also have different impeller rotational speeds. For the direct-drive compressor, the rotational speed of the impeller will be equal to that of the motor, whereas in the gear-drive compressor, the rotational speed of the impeller will be faster than that of the motor and reflect the gear ratio of the gearbox. The connection between motor and compressor can also be divided into two categories. The first category is the open type, where the compressor motor is cooled by means of either air or water and a coupling is used as a linkage between the compressor and the motor. The second category is the semi-hermetic type, which utilises liquid refrigerant to cool down the heat generated by the motor. If the first connection method is adopted, the heat generated by the motor will raise the temperature of the plant room; however, if the second connection method is used, the heat generated by the motor will be carried away by the liquid refrigerant, resulting in no temperature increase of the plant room.

Noise and vibration are closely linked to the compressor’s rotational speed; the faster the speed, the more noise and vibration generated. The rotational speed also affects a compressor’s durability. From the perspective of maintenance, in general a high speed wears out the compressor faster than low speed. With regards to the direct-drive compressor, the energy loss from the gears could be eliminated. The spinning part of a centrifugal type compressor is the impeller, which draws refrigerant through an inlet guide vane and adjusts the loading for the compressor. A multistage impeller arrangement can be used to alleviate the static pressure generated by the units. The outlet velocity from the impeller can be divided into two parts, namely the tangential velocity (Vt) and the radial velocity (Vr). The rate of tangential velocity is directly proportional to the impeller’s rotational speed and diameter, as is the rate of radial velocity to the mass volume of refrigerant gas (see figure 1).

The biggest chal lenge to be encountered during operation of a centrifugal type compressor is “surging

of compressor.” This can be categorised into two types, namely the “high load” surge and the “low load” surge. When the condenser tube is dirty, or the pressure at the discharge side of the compressor is higher than the normal operating pressure, or the water flow of condensing water is too low, then a high load surge will occur. This happens due to the pressure inside the condenser not being reduced during the normal condensing process and exceeding the resultant pressure generated by the impeller, resulting in the high-pressure refrigerant of the condenser flowing back to the compressor’s suction (see figure 2). This pressure release process is called “surge.” On the other hand, low load surge happens when low load scenarios occur. During low loading, the inlet guide vane will limit the refrigerant flow to the impeller and the radial velocity at the impeller outlet is reduced. Once the resultant refr igerant gas velocity from the impeller cannot overcome the refrigerant pressure at the condenser, the high-pressure refrigerant of the condenser will flow back to the compressor’s suction, resulting in a surge. For example, during winter and at night, the demand for air conditioning in buildings is relatively low, posing a higher risk of low load surge. The keys to prevent surge are proper selection of the compressor size in the design stage to match the condition of the site and the correct on-site operation of the chiller unit.

在中央空調系統中所使用之壓縮機有很多種類，最常使用的是離心式壓縮機。因為其製冷量較大，性能可靠，壓縮機更可在工地現場進行維修。

一般離心式壓縮機主要可分為直接驅動及齒輪驅動兩種。葉輪轉速是根據壓縮機各種型號之設計而定，當葉輪轉速和馬達轉速相等時，便會使用直接驅動壓縮機；假使葉輪轉速設計快於馬達轉速時，則採用齒輪驅動壓縮機。而馬達與壓縮機之間的連接方式可分為兩種：第一種是開放式，當中有風冷式馬達及水冷式馬達，壓縮機與馬達之間使用連軸器來接駁；第二種是半密封式，以液態冷媒來冷卻機組運行時所產生的熱量。馬達與壓縮機組件裝置在同一密封的冷水機組內，第一種連接方式的風冷式馬達在運行時所產生的熱量，會使機房溫度上升；而第二種連接方式的馬達在運行時所產生的熱量，會由液態冷媒直接把熱量帶走，不會使機房的溫度上升。

噪音及震動與轉速有直接關係，轉速越高，噪音及震動亦相對增加。轉速的快慢會影響壓縮機的耐用性，以維修角度來看，轉速快的損耗較轉速慢的為高。壓縮機如採用直接驅動，其需求軸承的數量會減少，同時亦可免除齒輪間之機械能消耗。

離心式壓縮機的運轉部份為葉輪。葉輪中心位置的吸入口裝有導葉片，其作用是將氣體引入葉輪及控制壓縮機的加減負載。離心式壓縮機葉輪的轉動是依靠馬達來驅動。壓縮機會使用一個或多個葉輪運作。為增加壓縮機的穩定性，多級葉輪可分擔機件運行時產生靜壓的任務。葉輪的氣體速度可分成兩個分力，切向分速度及徑向分速度。切向分速度的大小與葉輪旋轉速度和葉輪直徑成正比，徑向分速度的大小與冷媒氣體的流量成正比（見圖1）。

離心式壓縮機運作時面對最大敵人，便是喘震。喘震可分高負載喘震及低負載喘震兩種。當冷凝器水管污穢、壓縮機高壓端所排出的壓力過高及冷凝水的水流率過低等情況下，便會產生高負載喘震。當需要減少負載時導葉片會關上，流入葉輪的冷媒量減少，壓差增高時冷凝器高壓冷媒會倒湧回壓縮機（見圖2）。在低負載情況及冷凝器水水溫過高情況下，便造成低負載喘震，例如在冬季及晚間時段，大廈對空調的需求相對較低，便有機會出現低負載喘震的現象。保持良好的機組操作及使用多級葉輪，都是對抗喘震之有效方法。

Normally, the refrigerant volume remains adequate, and the velocity vector R combined by VR (vertical line) and VT is powerful enough to expel refrigerant out of the compressor. 正常時冷媒流量充足VR（垂直線）與VT結合的R合成速度矢量，足夠力量將冷媒推出壓縮機。
