Despite two of its cities – Phoenix and Tempe – passing maximum indoor temperature laws, the county registered 156 indoor heat-related deaths last year, a five-fold increase over the last ...
The regulations will require employers to monitor workers for heat-related illness and provide them water, breaks and cool areas when indoor temperatures hit 82 degrees Fahrenheit.
So, before you go instigating more thermostat wars with others in your household, consider these tips from experts about proper home temperatures for the winter. A thermostat set to more than 75 ...
For this model the standard provides a graph of acceptable indoor temperature limits at prevailing mean outdoor temperatures (a mean of the daily mean outdoor temperatures of the previous 7–30 days). An accompanying table lists provisions for higher operative temperatures at air speeds above 0.3 m/s (59 ft/min) and up to 1.2 m/s (240 ft/min).
United States Heating Degree Day map, 1961–1990 United States Cooling Degree Day map, 1961–1990. Heating degree day (HDD) is a measurement designed to quantify the demand for energy needed to heat a building. HDD is derived from measurements of outside air temperature.
For example, a conventional heat pump system used to heat a building in Montana's −57 °C (−70 °F) low temperature or cool a building in the highest temperature ever recorded in the US—57 °C (134 °F) in Death Valley, California, in 1913 would require a large amount of energy due to the extreme difference between inside and outside air ...
While this is ultimately a personal choice, most experts recommend turning on the heat in your home when the outside temperature is less than 55 or 50 degrees, or when the indoor temperature dips ...
In a desert climate where the outdoor temperature is 120 °F (49 °C), the maximum COP drops to 13, or an EER of 46 (for an indoor temperature of 80 °F (27 °C)). The maximum SEER can be calculated by averaging the maximum EER over the range of expected temperatures for the season.
