Are you searching for a new air conditioner? Are you considering a room air conditioner instead of a central air conditioning equipment but aren’t sure what you should be looking for? Purchasing an air conditioner of any type ought to be researched before hand simply as a result of amount of electricity your air conditioner could potentially use. If you purchase the wrong unit you may end up getting extremely large monthly electric bills and inefficient cooling 坐地冷風機.
As a consumer you certainly want to find a very good performing unit for you. You want to find a unit that is very energy efficient because not merely will it save you money in the long run, it’s better for the surroundings as well. Energy efficiency is about making the best or most efficient use of energy in order to achieve a given level of comfort and convenience.
What is a Room Air Conditioner?
A room air conditioner can be an air conditioning system made to cool a room or rooms instead of the entire house. Do you reside in a smaller home, townhouse, condo or even apartment? Would you prefer or do you require a non-permaneant air conditioning installation? If you answered yes a room air conditioner might be a good matched for you. Compared to central air conditioners, room ac units are dramatically less expensive to operate – even though they are often less efficient.
While central air conditioners often need higher voltage connections a room air conditioner can often be connected to any 15- or 20-amp, 115-volt household circuit. For those who have a larger room air conditioner you might need a dedicated 115 volt-circuit. In only the most extreme cases do you want to ever need a dedicated 230-volt circuit.
Room air conditioners tend to be vented or window mounted so they can effectively expel heat out. Be skeptical of any room air conditioner that will not offer proper ventilation.
How are Room Air Conditioners Rated?
If you are familiar with central air conditioners you may be already acquainted with the SEER or Seasonal Energy Efficiency Ratio. Room air conditioners are rated not on in SEER but instead in EER or Energy Efficiency Ratio. The EER of confirmed room air conditioner is calculated by dividing the cooling capacity in British Thermal Units (BTU) each hour by the power input in watts. You can get room air conditioners offering a range of cooling powers from 5,500 BTU each hour to 14,000 BTU per hour.
While the national appliance standard requires that any room air conditioning equipment built after 1990 with an EER of 8.0 or greater, and the most recent Energy Star standards require sometimes an EER of 10.7 or greater I support the American Council for an Energy-Efficient Economy’s (ACEEE) recommendations. The ACEEE recommends at the very least an EER of 11.6. Why? This can guarantee your unit is energy conserving throughout the year and when it is needed most – the latest summer months.
Selecting a Room Air Conditioner
Once you’ve decided to buy a room air conditioner be sure to look for the power Star label. If every room air conditioner sold in the U.S. were Energy Star qualified, we could prevent 1.2 billion pounds of greenhouse gas emissions to put that into perspective that’s equivalent to the emissions from 100,000 cars. Energy Star room ac units use at least 10% less energy than conventional models.
In the room air conditioner game Energy Star isn’t the only certification to be looking for. You should also search for Association of Home Appliance Manufacturers or AHAM Certified units. Why? AHAM Certified room ac units have their EER ratings verified by an independent laboratory .
