Chọn công suất điều hòa

Vấn đề đáng quan tâm nhất khi sử dụng máy điều hòa nhiệt độ là việc “tốn tiền điện”. Tuy nhiên, có một nghịch lý là cũng sử dụng điều hòa thời gian ngang nhau nhưng tiền điện hàng tháng ở các gia đình lại chênh nhau rất nhiều. Vì sao vậy?
Những gia đình tiêu tốn điện năng hơn như vậy, chắc chắn là gặp vấn đề về công suất của máy. Nhiều gia đình mua máy lạnh chỉ chú ý đến hãng, nhãn hiệu hàng hóa mà không để ý đến công suất của máy. Đây là một sai lầm dễ dẫn đến lãng phí điện năng trong quá trình sử dụng điều hòa âm trần. sửa chữa điều hòa
Một máy lạnh có công suất quá lớn không đem lại cho bạn sự thoải mái hơn, mà có thể đồng nghĩa với việc bạn phải mua với giá cao hơn và hoá đơn tiền điện hàng tháng sẽ tăng vọt. Ngược lại, máy có công suất nhỏ hơn yêu cầu, sẽ không cung cấp đủ độ lạnh cần thiết và hơn thế nữa máy có thể " Rớt lock" bất cứ lúc nào nếu chạy liên tục trong tình trạng thiếu công suất và nếu phải thay lock thì giá tiền có thể = 2/3 giá máy.
Cách chọn công suất máy lạnh đơn giản nhất.( Đúng 90%) : Đối với các hộ gia đình nhỏ, có thể dùng loại hai cục (Spilit type) hoặc một cục tuỳ theo cấu trúc nhà. Phòng có diện tích từ 9 ~ 14.5 m2 có thể gắn máy công suất 9.000 BTU/h (một ngựa), diện tích từ 15 ~ 20 m2 gắn máy 12.000 BTU/h (1,5 ngựa), diện tích từ 20 ~ 30 m2 gắn máy 18.000 BTU/h (2 ngựa), diện tích từ 30 ~ 45 m2 gắn máy 24.000 BTU/h (2.5 ngựa)
Và để chọn mua máy lạnh có công suất phù hợp, khoảng không gian trong phòng lớn hay nhỏ là yếu tố đầu tiên cần tính đến. Tuy nhiên, việc tính toán công suất máy lạnh dựa trên chiều dài, rộng, cao của căn phòng chỉ là sự tính toán bước đầu, công suất của máy lạnh còn phụ thuộc vào những yếu tố khác. Do đó, khi mua máy lạnh, bạn cần biết một số điều cơ bản sau: sửa chữa tủ lạnh
- Dòng nhiệt sinh ra từ trang thiết bị, con người: Những máy móc thiết bị và “hơi” người trong phòng sẽ sinh ra dòng nhiệt, nên công suất máy lạnh mà bạn chọn sẽ phải tính đến yếu tố phòng bạn thường có bao nhiêu người, đặt những trang thiết bị gì?, để cân đối lượng nhiệt phát ra và công suất máy. sửa chữa cây nóng lạnh

Chọn công suất điều hòa

- Ảnh hưởng của mặt trời: Những yếu tố nhiệt bên ngoài sẽ ảnh hưởng đến độ lạnh của phòng. Bạn hãy xem phòng bạn là hướng đông hay Tây, có bị ảnh hưởng bởi mặt trời không. Loại màn cửa mà bạn đang sử dụng dày hay mỏng, khả năng cản sức nóng nhiều hay ít? sửa chữa điều hòa
- Tường và trần nhà: Vật liệu làm tường và trần nhà của bạn có ảnh hưởng rất lớn đến năng suất lạnh của máy. Khi tường và trần nhà không được cách nhiệt tốt, hệ số truyền nhiệt tăng lên, kéo theo chi phí cho năng suất lạnh của máy cũng tăng theo.ngoài ra màu sắc cúng ảnh hưởng đến việc hấp thụ nhiệt. Màu sáng sẽ ít hấp thụ nhiệt nên sẽ đõ tổn hao công suất lạnh. Điều hòa tủ đứng
- Hệ thống thông gió: Nếu hệ thống thông gió hoạt động quá tốt (quạt hút, khe hở, cửa đóng mở liên tục, quá trình lạnh sẽ lâu hơn và máy hoạt động nhiều dẫn đến tăng điện năng tieu thụ. Do đó khi trang bị máy lạnh, bạn nên hạn chế việc thông gió bên trong không gian điều hòa với môi trường bên ngoài.
- Ánh sáng: Các loại đèn khác nhau sẽ sinh ra nhiệt khác nhau. Đèn huỳnh quang phát nhiệt ít hơn các loại đèn khác, điều đó cũng có nghĩa chi phí cho năng suất lạnh của máy sẽ giảm đi.
Như vậy, khi mua máy lạnh cần xem xét, tính toán tất cả các yếu tố có thể tác động đến hoạt động của máy để có thể chọn cho mình một máy lạnh có công suất phù hợp nhất. và muốn được đều đó bạn cần chuyên gia tư vấn am hiểu về chuyên môn củng như giá cả thị trường để tư vấn cho bạn rõ ràng nhất.

Escaping the cold in Hanoi

For a city that’s cold and grey for a few months of the year, Hanoi has an unfortunate lack of venues to get cosy in. But in the absence of open fireplaces and comfy sofas, here are a few places we’ll be spending time this winter. Hanoi Cycling Tour
Blankets are one option.
Drinking tea or coffee might be great for warming up, but in the open-fronted — or outdoor — coffee shops in Hanoi you’ll still need to keep your coat on. For somewhere a bit more weather-proof head south to Cong Caphe or over to Cafe Duy Tri near West Lake. The seats at Duy Tri aren’t designed for spending time on, but it’s certainly cosy (that is, small) and the tasty drinks — and free WiFi — can keep you occupied for hours. For a more tourist- and Western-orientated coffee drinking joint try old-timer Puku, which at least has the sofas, if not the fireplace. And the cakes are good so you can fatten up to ward off the cold. The cakes are also good at Joma on Ly Quoc Su. Hanoi Walking Tour
Or try a hot ginger and lemon tea.

Escaping the cold in Hanoi

If you’re more a fan of alcoholic beverages then our top picks are Polite Pub on Bao Khanh, Finnegans on Luong Ngoc Quyen and Le Pub on Hang Be. We particularly like Polite Pub for its gloomy — in a good way — atmosphere, cold draft beer and music, but the large pool table is a draw as well. Finnegans is as close to an Irish pub as you’ll get here and has high-backed booths, both of which are high on the list of “things which make a pub cosy”, and shows sports on a large screen. Finally, the newly decorated upstairs area at Le Pub is well protected from the outside elements and offers a decent comfort food menu.

• MANGO CRUISE

Outside of Hoan Kiem district, if you’re over near West Lake check out Red River Tea Rooms which is heated and provides a selection of  boardgames and books, which can be enjoyed in the comfy back room — or anywhere in the pub really, there are no rules. Down towards Vincom, round the corner from DC Bistro, you’ll find Tadioto. This very highly-regarded hangout actually does have a fireplace, but even without it, it’s still a very welcoming place to while away the hours, either during the day or all night.
Icy glasses aren’t really necessary in this weather.
Our final bar recommendation is Bar Betta. The eclectic inside area is comfortable and inviting and cuddling up under the space heaters on the roof terrace you feel like you’re cheating the temperature. Shame the service is poor.
But if money were no object we’d be spending more time at the Bamboo Bar at the Sofitel Metropole Legend Hotel. It may be an outside bar but blankets are provided to accompany your hot winter drink — try the hot cider — and a visit alone is enough to jerk us out of our winter blues.
Of course, if you want to stay out and about, absorbing Hanoi’s unique culture, then wrap up and warm yourself from the inside out with hotpot or a steaming bowl of pho. Above all, don’t let the cold put you off. Hanoi is a fantastic place to visit at any time of year — you just need to come prepared.

The Muong group and their typical culture

The Muong have a population of around 1 million who live mainly in northern provinces like Hoa Binh and Thanh Hoa. The Muong culture is related to Hoa Binh culture dating back more than 10,000 years.
The Muong share ethnic roots with the Vietnamese people and their language is classified in the Vietnamese – Muong language branch. The Muong live in mountainous areas which have abundant land for growing wet rice. In a Muong hamlet, stilt houses shelter in the shade of big trees, huddle against the mountain, and look out on vast rice fields. A Muong house is designed to maximize convenient use and air ventilation to counter the warm, humid mountain climate. Sapa Vietnam tours
The Muong’s costume is special. Men often wear a round-neck shirt which opens in the front and has two pockets. Their pants have large trouser legs. On special occasions, the Muong men wear a purple or yellow silk shirt inside a long, white ceremonial robe. Quach Van Suong of Vo Do hamlet, Nhan Nghia commune, Hoa Binh, said: “When we were small our elders taught us the typical cultural features of our group reflected in our costume. We like to wear our traditional clothes every day as well as at festivals. It’s a way to preserve our culture for our children.”3 days to the Floating Markets 
The Muong women wear a long, black dress and a white or brown shirt with a line of buttons in the front and long sleeves. They wind a white or indigo headscarf around their head. The highlights of the Muong costume are embroidery on the dress hem and belt. It requires skill and artistic talent to design the patterns and harmonize the colors of the costume. Quach Thi Lan of Nhan Nghia commune says there are 40 popular patterns, of which the dragon is the favorite image. “The most important step in weaving a dragon is to count the threads used to make the dragon head, wings, and body. We have to consider the position of each part and mix white, black, and red to make a soaring dragon.”best cruises in Halong Bay

The gong is the most popular musical instrument along with the flute, the two-string violin, the drum, and the panpipe. Bui Thi Xuan, a member of the Club for preserving the Muong culture in Luc Doi hamlet, said the Muong have folk songs for every event such as a house warming, duet singing in the spring, and long epics. “The Club is collecting old songs to teach the children. Young people learn songs to sing during daily activities or at a wedding ceremony. When I was young, we worked and sang songs all the time.”

Depending on habits of specific ethnic groups, marriage includes various steps and related procedures, but in general, there are two main ceremonies:

Le an hoi (betrothal ceremony):

Normally, both bride and groom or their parents go to the fortuneteller to see what date and time is best for them. They strongly believe in this date and time so the groom's family and relatives must come on time. Some days before the wedding, they will visit the bride and her family with round lacquered boxes known as betrothal presents. It composes of areca nuts and betel leaves, tea, cake, fruits, wines and other delicacies which covered with red cloth and carried by unmarried girls or boys. Don ca tai tu – The soulful voice floating along rivers

Vietnamese wedding ceremony

The groom's family would introduce themselves and ask permission for their son to marry his bride. The master of the ceremony (usually a respected person among the bride's relatives) instructs the bride's parents to present their daughter. The bride then follows her parents out. She will wear red traditional wedding ao dai, followed by her bride maids. The couple should pray before the altar ask their ancestors for permission for their marriage, then express their gratitude to both groom’s and bride’s parents for raising and protecting them.

Then, they bow their head to each other to show their gratitude and respect toward their soon-to-be husband or wife. The master of the ceremony would gave the wedding couple advices on starting a new family. Their parents would take turn to share their experience and give blessing. After that, the groom and the bride exchange their wedding rings and receive the gifts from their parents such as golden bracelets, ear rings, necklace... The ceremony is ended with a round applause.

After the wedding ceremony is over, there will be a party at the groom's house. Some traditional Vietnamese wedding party is celebrated at their houses (usually in country-side); other is celebrated in the restaurant. This day is the culmination of desires, day dreams, hopes and anxieties. There is a band to play music during their meal. Some guests are free to sing related wedding songs on the stage to luck the bride and the groom. In the middle of the party, the couple goes to each table to get wishes, congratulations as well as money.

Today, a lot of Vietnamese couples have their wedding ceremony done in Temples or Churches which is very much similar to American and Western style, including exchanging vows and wedding rings. However, they still maintain Vietnamese traditional ceremony in the bride's home before heading to temples or churches.

Mon canh (meal with soup) consists of a soup made with pork or spare-ribs, crab meat, and fish.
In the past several years, people in urban centers have begun to go out for lunch at the food stalls on the street. Consequently, there has been a proliferation of temporary food stalls along many sidewalks and public spaces in the cities. Some stalls are open until early in the morning to cater to regular customers. Around noon, owners can be seen arranging tables and benches along the pavement to form makeshift shop floors. After two or three hours, when there are no more customers, they begin to remove all of their wooden furniture, so that the place resumes its former appearance. A well served lunch for one is very inexpensive. Mekong & Phu Quoc island (5 days, 4 nights)
Banh Chung (Sticky Rice Cake)

3 famous dish in Vietnam

Sticky rice cakes are a Vietnamese traditional dish that must be part of Tet meals. As a matter of fact, every Vietnamese family must have sticky rice cakes among the offerings placed on the altar to their ancestors. Vietnam tours
Bang chung is made of glutinous rice, pork meat, and green beans paste wrapped in a square of bamboo leaves, giving the rice a green colour after boiling.
According to the legend, under the reign of the Hung Kings, Prince Lang Lieu created sticky rice cakes and presented them to his father. Bang chung won high acclaims from the King who awarded the prince his throne.
Making sticky rice cakes is a very meticulous job. To obtain the best cakes, rice has to soak in water for an entire day. The pork meat must include skin and fat, the green beans must be of the same size, and the bamboo leaves must be fresh. Squaring off and tying cakes with bamboo strings requires skilful hands.
Sticky rice cakes are available at any time of the year, although one is sure to enjoy them with relatives and friends during Tet. During Tet, rice cakes are served with gio lua and hanh muoi� lean meat pie and salted sour onions.

Lean pork pie is available in Vietnam only and has different names in the north and south. Foreigners as well as Vietnamese are fond of lean pork pie.
Gio lua consists of pork meat wrapped in fresh banana leaves. The little bundles are then boiled. The most delicious part of lean pork pie is the top layer since it absorbs the flavour of the banana leaves.

Pho - Noodles
Pho is the most popular food among the Vietnamese population. Pho is commonly eaten for breakfast, although many people will have it for their lunch or dinner. Anyone feeling hungry in the small hours of the morning can also enjoy a bowl of hot and spicy pho to fill their empty stomachs.
Like hot green tea which has its particular fragrance, pho also has its special taste and smell. Preparations may vary, but when the dish is served, its smell and taste is indispensable. The grated rice noodle is made of the best variety of fragrant rice called Gao Te. The broth for Pho Bo (Pho with beef) is made by stewing the bones of cows and pigs in a large pot for a long time. Pieces of fillet mignon together with several slices of ginger are reserved for Pho Bo Tai (rare fillet). Slices of well done meat are offered to those less keen on eating rare fillets.
The soup for Pho Ga (pho with chicken meat) is made by stewing chicken and pig bones together. The white chicken meat that is usually served with Pho Ga is boneless and cut into thin slices. You could consider Pho Bo and Pho Ga Vietnam's special soups. Pho also has the added advantage of being convenient to prepare and healthy to eat.

Cha Ca (grilled minced fish)
 Grilled minced fish has been served in Vietnam for more than 100 years. The Doan family of Cha Ca Street in Hanoi first invented this dish.
A wide variety of fish can be used in this dish including sturgeon and tuna. Tuna is low in fat, has an exquisite flavour, and few bones. The bones are separated from the meat and put into saffron water to be later used in a sauce. The fish is marinated in salt before being grilled.
What is interesting about this dish is that people can add their favourite condiments: coriander, mint, dill, shallots, and more.
