Portable ACs are the perfect portable cooling solution for areas where installing standard air conditioning systems may be cost-prohibitive, impractical, or impossible. This is especially true in settings such as apartment buildings or server rooms located within an interior of a building. Moreover, portable air conditioners are compact, easy to maneuver, do not require permanent installation, and because they're most often used to cool specific areas as opposed to entire homes or buildings, they are quite energy-efficient as well. With regards to design, portable air conditioners are simple cooling devices. The box-like housing of the unit holds the cold and hot sides of the air conditioner in one while an exhaust hose expels heat. Water is condensed out of the air which is then collected in an internal drain bucket or through a drain hose. Furthermore, some portable ACs even utilize advanced evaporative technology and thus produce very little or no water at all. In addition to the above benefits, portable air conditioners are also multi-functional and offer more than just cooling.

The refrigeration cycle utilized by these portable coolers dehumidify moisture from the air, and some units even come with built-in heaters and air purifiers. Nonetheless, when it comes to choosing a portable AC , one of the most common mistakes consumers make is incorrectly sizing their unit. Portable air conditioners are sized according to BTUs, which stands for British Thermal Units. how much copper is in a outside ac unitA BTU is a unit of energy that is commonly used in the power, steam generation, and heating and air conditioning industries. 3 ton hvac unit costGenerally speaking, a portable air conditioner's BTU rating describes its power and cooling capacity. home air conditioner compressor not working onNaturally, the higher the BTUs, the stronger the portable AC. Portable air conditioners have cooling capacities that usually range from 5,000 BTUs to as high as 30,000 BTUs, and the size needed to cool a room will depend on the area being cooled. 

Thus, an incorrectly sized portable AC with insufficient or excess BTUs will result in inefficient cooling. After these have been verified, it is then time to determine your BTU requirements. Simply look to the chart below: Portable Air Conditioner Sizing ChartSquare FootageRequired BTUs Recommended Air Conditioner100 - 200 7,000 - 8,000 American Comfort ACW200C150 - 250 8,000 - 10,000 NewAir AC-10100H250 - 350 10,000 - 11,000 NewAir AC-12100E350 - 525 12,000 -16,000 Soleus LX-14020' x 20' = 400 square feet  400 square feet = at least 12,000 BTUs As such, if your room measures 400 square feet, you will need a portable air conditioner that offers 12,000 BTUs of cooling. However, please note that the figures in the chart above are estimates based on average room conditions in a moderate climate. Some exceptions may also apply, and these are listed below: For second story homes or especially sunny areas, add the BTU amount by 10% For shaded areas, reduce the BTUs by 10% For each additional person over two persons in a room, add 600 BTUsTo cool a kitchen, add 4,000 BTUs

A wide variety of indoor unit designs and outdoor unit capacities ensures the flexibility to meet the most challenging of air conditioning needs. From aesthetic wall-mounted and floor-standing designs to ceiling-recessed cassettes, abundant options are available to match virtually any interior design. Many systems are equipped with the "l-see sensor", an original Mitsubishi Electric technology that realizes better air conditioning control. This is combined with other industry-leading energy-saving and silencing technologies to produce air conditioners that provide optimum performance and room comfort wherever they are installed. The Mr. Slim Series of small- to medium-sized split-type room air conditioners offers the convenience of being compact yet powerful; a combination ensuring excellent performance and easy installation. Available in a variety of capacity and design combinations, the Series is ideal for creating a "best match" system for your air conditioning requirements. Inverter-based units promise industry-leading quiet operation and a high coefficient of performance (COP).

Mitsubishi Electric's VRF air conditioning systems offer the luxury of distributed airflow and the independent control of indoor units. Installation flexibility and a wide selection of indoor unit designs and outdoor unit capacities ensure "best match" solutions for air conditioning needs, even for the most diversified requirements. Consideration for the environment during development has led to the manufacture of powerful, compact units that consume minimal energy, have a high coefficient of performance (COP) and contribute to maximum room comfort. The unique Lossnay heat-exchange technologies developed by Mitsubishi Electric help refresh a room's air while leaving temperature and humidity largely unchanged. The Lossnay core is comprised of a diaphragm constructed of specially processed paper configured into a cross-flow, plate-fin structure. The advanced heat-transfer and moisture permeability properties of the paper help maximize the recovery of heat as air is circulated through the element.

The result is substantial energy savings and a more comfortable indoor environment. Lossnay ventilators can be used alone or in combination with other air conditioning/ventilation systems. To meet the needs of open-front stores and shops in shopping malls, building complexes and street-level businesses, Mitsubishi Electric developed a line-up of high-performance air curtains. These systems create a wall of air that protects the interior space from climatic temperature swings, polluted air, etc. Both quiet and powerful, our systems are an energy-efficient solution for providing enjoyable indoor environments that are clean and comfortable. Mitsubishi Electric manufactures a line-up of powerful rotary compressors designed to suit a variety of applications and operate smoothly even in harsh environments. Our advanced scroll compressors utilize a "Frame Compliance Mechanism (FCM)," a state-of-the-art technology that maximizes energy usage and reduces friction, thereby ensuring less vibration, higher durability and low-noise operation.
