Small is beautiful and convenient and so is the portable air conditioner as it can be shifted from one place to the other very easily. Read on to find out all the other advantages.

With the onset of the damp weather, it becomes difficult to survive without constant central air conditioning but that can prove to be quite expensive. The answer to this problem is a portable air conditioner as it has many advantages. It is easy to shift from one place in the home to another and that makes a portable air conditioner the ideal cooling system solution for your home, office or industrial site.

The portable air conditioners are easy and quick to install, as they do not involve any lifting or tearing up of windowsills. Moreover it can be shifted very easily from one place in the home to the other. For taking care of the hot spots in the central air conditioning, the portable air conditioners are far more convenient than window air conditioners. It is also ideal for window shapes, which present problems for installation. There is nothing like portable air conditioners for use as a spot cooler in the home.

A portable air conditioner is an excellent choice for saving money as just one unit needs to be purchased and it can be shifted easily to where you need it as it is mounted on castors and some can weigh only about 36 pounds. Moreover, as only one room is cooled at a time instead of the whole house, the total energy consumption is very low as compared to other air conditioning systems.

Another advantage of portable air conditioners is the energy efficiency that they provide. The average efficiency is in the 8 to 10 range although some are as high as 15, which is 50 percent better than most older central air conditioners. The small size of the portable air conditioners is very advantageous and as such it can fit in a corner or against a wall. It functions like an effective dehumidifier if you do not vent the warm exhaust air out through a window and its size is also the same as that of a room dehumidifier.

In order to reduce humidity and allergies, even the small ones remove 35 pints of moisture per day from the room air. The portable air conditioners also use the heat-exchange principle as the other air conditioners to cool and dehumidify the air. The operating principle is also similar to a window air conditioner as the room air circulates over cold evaporator coils to cool and dehumidify it inside the unit. The room air is exhausted outdoor after flowing over the hot condenser. There is no chance of already-cooled indoor air escaping outside as two ducts are now used.

Nowadays, you have electronic controls in most models and you can set the desired room temperature, blower speed, start and stop timer, and operation mode (cool, dehumidify, heat). The portable air conditioners also have hand-held remote control with which you can conveniently change all the settings as per your need.

The other features of portable air conditioners include a built-in air cleaner with an optional charcoal filter and oscillating louvers to distribute the cool air throughout the room. You can also switch off the louvers to direct the flow of air towards yourself, if you so desire.

yoga has had resurgence in popularity over the last few decades and new classes form everywhere every day. Thousands of new teachers are certified every year, but with such a large percentage of new teachers, how can we be sure we're getting the yoga knowledge and teaching ability we seek?

The different schools of yoga are really all based on the same movements, or yoga asanas, but they do it in different tempos and combinations in order to achieve specific results. The school's stated purpose can be a good place to start. For example, if you're looking to lose weight, you'll want one of the quicker-paced schools. If you're looking for spiritual repose, you may prefer a slower-paced yoga with longer holds. This is largely a matter of personal preference, and several schools may all meet a single type of need, so don't give up if the first one you choose isn't what you hoped for.

Finding the right kind of teacher to whom you'll respond isn't always easy. In the first place, there is no real certification processed or approved training sequence. Without these standards almost anyone can hold themselves out as professional yoga instructors.

Find out what kind of training a proposed teacher has had. What school of yoga did he study? How many hours did he put in before becoming a teacher? A program that includes not only learning, but also practice teaching sessions, and is around 200 hours seems to be standard. You'll find some certification programs that take a year or more to complete, and those that are an intense weekend of correspondence-type study. Expect to pay more to and learn more from the former. Avoid the latter altogether.

Also check his experience. How long has he been teaching? Usually, the longer the experience, the better the teacher, but if he's new, don't rule him out on that alone. Talk to some of his students. What do they like about him and what would they change? How do they feel after a session with him? compare their answers with your ideal of a yoga instructor.

If you're new to yoga, you may want to have a discussion with a potential instructor. Find out how she got into yoga, and what styles and schools she's tried. Ask what she focuses on the most in her classes - strength? Flexibility? Balance? Meditation? Does she limit the size of her classes? If you're attending for a specific medical reason, such as high blood pressure or back pain, make sure she has experience with those conditions.

Some good clues to look for are 1) is the teacher enthusiastic about yoga and its myriad of benefits for students? 2) Does he seem knowledgeable, using sanskrit names for the asanas? These things don't guarantee expertise, of course, but they indicate a good amount of time spent in study.

After you've checked her credentials and chosen your yoga instructor, try a few lessons before you commit to any length of study. You'll want to assure yourself that you and she are compatible as student and teacher. Do you like the routines she leads? Do you find her instruction easy to follow? Does she give individual help when you need it? Does she provide demonstrations? Does she care about her students and watch over them carefully to assure they are doing the asanas correctly and in a way they aren't prone to injury? Does she correct not only with words, but also with gentle physical repositioning? Are you overly sore when you finish a session? This may be a sign of an unbalanced routine and another teacher may be in order.

Again, don't be discouraged with a bad teacher. Just try again. There's always another, better, yoga teacher just around the corner.
