With the ability to extract up to20 litres a day, the powerful dehumidifier setting can help prevent health problems that result from condensation, mould and damp.

There is also a difference if you live in Texas or New York. The local climate in Texas is, on average, hotter, and therefore you should need an air conditioner with a few 1,000 BTU more. Portable units running of 110/120V go up to 15,000 BTU (above that, you’ll need 220/240V voltage). Obviously, dual hose units are better (higher efficiency, lower long-term costs; based on EER rating). Use this calculator to estimate the cooling needs of a typical room or house, such as finding out the power of a window air conditioner needed for an apartment room or the central air conditioner for an entire house. SizeFor example, a home owner in Atlanta might want to determine their BTU usage during winter. Atlanta winters tend to hover around 45°F and temperatures may fall as low as 30°F occasionally. Given that the desired temperature of the residents is 75°F, the desired temperature increase would be 75°F - 30°F = 45°F.

Cons: Set up took longer than others, one-year warranty, terrible energy efficiency compared to window ACs The British Thermal Unit, or BTU, is an energy unit. It is approximately the energy needed to heat one pound of water by 1 degree Fahrenheit. 1 BTU = 1,055 joules, 252 calories, 0.293 watt-hours, or the energy released by burning one match. 1 watt is approximately 3.412 BTU per hour. Now, the people are what really makes the difference here. According to the AC sizing, you have to add 600 BTU for each person if there are more than 2 persons in the room. In your case, you will have to add (in theory) 148 x 600 BTU = 88,800 BTU or 7.4 tons. So, combined, you are looking at a theoretical calculation of 14.15 tons. That’s quite a lot. When used in relation to air conditioning systems or heaters, the measurement is expressed in terms of how many BTUs per hour the product can add or remove from the air. After adding 10%, you will have a better estimate of the cooling power you will need for this space. This is due to the added ambient heat added due to the environment. This may mean going up to the next available cooling power.

Air conditioners with HVAC filters can also help filter the air in your home, which can come in handy if wildfire smoke is a threat where you live.
