Yazd is offering a range of new heat pumps. Take a moment to browse through our extensive selection, including our money-saving low-energy models.
How Does a Heat Pump Work?
A heat pump uses electrical energy move air from one space to another. On cold days, it draws heat from outside and funnels it inside. On warm days, the process can be reversed, and draws warm air from inside a space and deposits it outside.
Terms to Know when Choosing Equipment
COP stands for Coefficient of Performance. The coefficient of measures the amount of the heat removed at colder temperatures against the work required remove it. This tells you how efficient an AC or heating system is at cooling or heating a space.
EER and SEER
EER stands for Energy Efficiency Ratio, and SEER stands for Seasonal Energy Efficiency Ratio. The EER of a unit measures its cooling capacity (which is measured in Btus per hour) against the amount of energy that it receives (which is measured in watts) under a specific set of rating conditions. The SEER is the EER measured over an entire year. The EER and SEER of a unit measure the energy efficiency of an AC unit, and the higher the rating, the more efficient the unit is.
HSPF stands for Heating Seasonal Performance Factor. HSPF is an energy efficiency rating that works very much the same as SEER. However instead of an AC unit, it applies to heat pumps. Like SEER, the higher the HSPF rating, the more efficient a heat pump is at heating your building.
Ton is a term that refers to an air conditioner’s cooling capacity. One ton of refrigeration is equal to 12000 BTU (British Thermal Unit). Each home requires a different tonnage of refrigeration to cool. The tonnage required depends on a number of different factors, including location, size and insulation.
An Important Note
According to the US Department of Energy, all new central air conditioners and heat pumps sold in the US must have a minimum of 13 SEER. This marks a 30 percent increase in energy efficiency from previous mandates.
