efficient home heating on all but the coldest days. When the temperature outside drops too low for the heat pump to operate effectively, the system will instead use the furnace to generate heat. This kind of system is often called adual fuel system– it is very energy efficient and co...
Definition of latent heat of vaporization.Definitions of AFUE, BTU, BTUH, EER, SEER, HSPF and other energy usage and equipment efficiency measurements.Definition of SEER - Seasonal Energy Efficiency RatioSEER stands for "Seasonal Energy Efficiency Ratio. This is a measure of the energy efficiency ...
HVAC stands for heating, ventilation, and air conditioning – the systems that work together to keep your home a comfortable temperature and improve air quality.
HSPF stands for Heating Seasonal Performance Factor and measures the efficiency of a heat pump over the fall and winter seasons. HSPF2 is an updated version of HSPF set by the Department of Energy (DOE) that goes into effect Jan. 1, 2023. The DOE created HSPF2 after refining HVAC system...
The thermostat device is a part of the AC system that helps to control the degree of temperature in the room. Heat Seasonal Performance Factor (HSPF) Heat Seasonal Performance Factor is a rating that is based on the efficiency of a heating system. It compares the amount of heat produced dur...
Estimated Heat Pump Size: Using this calculator, everybody can roughly estimate what size heat pump they need. This is primarily a mini-split heat pump size calculator but can be used to roughly estimate the size of ground-source or even water-source heat pumps. ...
current draw decreases. However, a constant volume ECM will ramp up in a futile attempt to maintain programmed airflow. ECM powered fans, starved of air, will simply move whatever they can get at a higher velocity. Motor wattage increases considerably, blowing AHRI rated SEER and HSPF numbers...
Knowing what a good SEER rating of an air conditioner is essential. You can use this calculator below to calculate the yearly electricity cost for every air conditioner. We predispose the 1,000h/year operation use and 13,19 cent per kWh to calculate the electricity bill based on BTU and ...
