冷氣機慳電耐用3貼士 Aircon energy saving tips

冷氣機是炎夏「涼」伴，不少家庭會長時間開冷氣機，究竟開足24小時是否要熄機停一停？反覆開關冷氣是否更耗電？前理工大學機械工程系工程師、英國機械工程師學會院士盧覺強接受明報網站訪問，解答冷氣機使用的3個疑問，並提供冷氣機慳電及耐用的貼士。

1. 又開又關，慳電定嘥電？

盧覺強：冷氣機開動的一刻，須使用較高電流驅動壓縮機運作，因此反覆開關會消耗更多電力。他續說，反覆開關導致機內負責製冷的壓縮機喉管閥門損壞，增加冷媒泄漏機會，令冷氣機整體製冷效能降低，要使用更高功率才達到同樣的製冷效果。

【小貼士】反覆開關耗電又傷機，盧覺強建議，關機後最少等待15分鐘才再次開動。

2. 冷氣機長開要按時關機？

盧覺強：冷氣機不應開動長達24小時，因為長時間運作會容易令機件磨損，出現震動，影響「壽命」。

【小貼士】冷氣機應每運作12小時便關機休息，家中冷氣機可輪流使用，例如：日間開客廳冷氣，晚間才開睡房冷氣。

3. 隔塵網不乾淨影響冷氣機「壽命」？

盧覺強：隔塵網不乾淨不會影響冷氣機「壽命」，不過會令冷氣機更耗電，因為這會令冷氣機入風量減少，降低製冷效能，機內恆溫器不能控制製冷功能適時停止，最終冷氣機要花更多時間製冷，令耗電量增加。

【小貼士】定時清潔隔塵網，乾淨又慳電。

家務助理導師教你2招清洗隔塵網

（資料來源：明報 28-06-2017）

夏天歎冷氣要夠涼快，必須定期清洗隔塵網，不懂如何清洗？香港資深家務助理導師張鳳娟（Winnie）分享2個清洗冷氣隔塵網的貼士。

1. 勿用刷子洗隔塵網

不少人會用刷子清洗隔塵網，這樣會令隔塵網的孔變大，影響隔塵功能。她表示，清洗時只要用花灑沖洗便可。

2. 沖水時有塵一面向下方

用花灑沖洗隔塵網時，有塵的一面要向下，才可沖走積在隔塵網上的塵粒。

【知多啲】關冷氣後勿立刻開窗

關掉冷氣後，不少人會開窗讓空氣流通，不過，張鳳娟提醒，關掉冷氣的半小時內都不宜開窗，因為室外的熱空氣吹入氣溫較低的室內時會變成濕氣，容易令家居牆壁和地板受潮。張建議，應待室內溫度提高後再開窗較理想，若擔心關窗令室內空氣不流通，可以開抽氣扇或風扇。

洗衣機藏邋遢 梳打粉助去穢

洗衣機常處於潮濕狀態，加上每次洗衫，衣物上的污垢、清潔劑的殘餘物皂垢，都會積在洗衣機裏，導致大量細菌滋生，所以須定期清洗。

清潔方法很簡單，只要用具有「碳酸氫鈉」成分的梳打粉便可，因除有清潔除臭效果外，亦能軟化水質。先把洗衣槽放滿熱水，然後加入約100g梳打粉，讓洗衣機攪動5分鐘，然後讓它待一小時。把水放掉後，再以一般洗衣程序再洗一次。

如何不交Membership fee而能在 Costco 購物 – How to shop in Costco without membership

To buy most goods, you must be a member or have a member make the purchase

Of course, you might not be comfortable doing that and it could get old pretty quick for the member. There is another way…

“We will refund your membership fee in full at any time if you are dissatisfied.”

So, you could pay your membership fee, give it a trial run, and if you feel you are not getting the value from it that you’d like – ask for a refund. You can do so at any time.

But what if you just want to get in the door and walk around to see what Costco has to offer, pricing, and all that good stuff – but you don’t know a member you are comfortable tagging along with?

Non-Members Can Purchase from Costco.com

Non-members can purchase from Costco’s website, Costco.com, at any time. There is a downside, however:

“Non-members will be charged a 5% surcharge over the member’s posted product prices (except for prescription drugs).”

The food offering on Costco.com is extremely limited as well.

The Costco Cash Card Can be Used by Non-Members:

Costco also has a cash card (gift card). With a Costco cash card, any non-member can show the card to get in the door and use it to make a purchase.

Costco cash card can be purchased by a member only. Once the card is depleted, you’ll have to get another fresh one from a member.

If you know someone who is game, one or two cards wouldn’t hurt. I have heard (not tested), that the entire purchase does not have to be made with the card. In other words, if you only had $10 left on a card and had $150 worth of purchases, you could use the card for $10 and then use another form of payment for the remainder. Which is a great segue…
Costco Forms of Payment:

While you may get in the door and even be able to purchase items, note that Costco stores do not accept Discover, American Express, or MasterCard credit cards as payment. Accepted forms of payment include: cash, check, debit cards, the previously mentioned Costco cash cards, and Visa credit cards (including the Costco branded Costco Anywhere Visa Card, which gets 2% cash back on Costco purchases.
