BTU stands for the British Thermal Unit, defined as the amount of heat necessary to raise the temperature of one pound of water, one degree. The typical heat gain added to a room by a person at rest is about 230 BTUs per hour. So, a 10,000 BTU window air conditioner is capable of removing 10,000 BTUs of heat per hour. The higher the BTU, the easier and faster it is to cool a room.
Seasonal energy efficiency ratio - Seasonal Energy Efficiency Ratio (SEER) is a measurement of efficiency for cooling devices such as heat pumps and air conditioners. A unit's SEER is calculated by dividing the total number of BTUs of heat removed from the air by the total amount of energy required by the unit. Energy efficiency - In physics and engineering, including mechanical and electrical engineering, energy efficiency is a dimensionless number, with a value between 0 and 1. The energy efficiency of a process is defined as: EU energy label - According to an EU Directive most white goods and light bulb packaging must have an EU Energy Label clearly displayed when offered for sale or rent. The energy efficiency of the appliance is rated in terms of a set of energy efficiency classes from A to G on the label, A being the most energy efficient, G the least efficient. National Energy Action - National Energy Action (NEA) is a UK charity that combats the heating and insulation problems of low-income households by encouraging the use of energy efficiency services. They deal with government, private, and consumer organizations to end fuel poverty and create campaigns for greater investment in energy efficiency to help those in need. windowenergyefficiency |
