Now, the first heat wave has arrived in the northeast, causing many homes to crank their air conditioners. Temperatures have been in the 90s this week, and the real feel could be over 100 degrees ...
These energy-saving tweaks saved as much energy as shutting off 10,000 to 15,000 window AC units across Eugene, according to an EWEB press release. ... both during the day when they were home and ...
The general rule of thumb for efficient air conditioning systems is one degree per hour. That means if your air conditioner is sized right, dropping the temperature four degrees will take about ...
The energy efficiency ratio (EER) of a particular cooling device is the ratio of output cooling energy (in BTUs) to input electrical energy (in watt-hours) at a given operating point. EER is generally calculated using a 95 °F (35 °C) outside temperature and an inside (actually return-air) temperature of 80 °F (27 °C) and 50% relative humidity.
EER is the Energy Efficiency Ratio based on a 35 °C (95 °F) outdoor temperature. To more accurately describe the performance of air conditioning equipment over a typical cooling season a modified version of the EER, the Seasonal Energy Efficiency Ratio (SEER), or in Europe the ESEER, is used. SEER ratings are based on seasonal temperature ...
Efficient energy use, or energy efficiency, is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems. For example, insulating a building allows it to use less heating and cooling energy while still ...
An HVAC specialist offered some tips and tricks for saving energy, cutting costs and keeping your home cool. Jen Uttke, fourth generation owner of Uttke heating & cooling , said her best advice is ...
The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required. [1][2] Higher COPs equate to higher efficiency, lower energy (power) consumption and thus lower operating costs. The COP is used in thermodynamics.
