What Is A Heat Pump?
A Heat Pump is basically an Air Conditioner that can change cycles from cooling to heating and vise
versa. It uses the evaporation of a refrigerant, to provide cooling or heating depending on the signal
of the thermostat. The mechanics evaporation cycle are the same in a refrigerator as in an air
conditioner. The term, Freon, is the term used for any of various nonflammable fluorocarbons used as
refrigerants and as propellants for aerosols.

| HOW DO HEAT PUMPS WORK? How the COOLING cycle of a Heat pump works: 1. When the heat pump is switched to the cooling mode at the thermostat, The compressor starts and the reversing valve solenoid is left in the de-energized position. The outdoor coil is now dissipating heat to the outside air and the indoor coil is absorbing hot air from inside the home. How the HEATING cycle of a Heat Pump works: 1.When the heat pump is switched to the heating mode at the thermostat, The compressor starts and the reversing valve solenoid is energized, allowing the valve to reverse the direction of refrigerant flow. The outdoor coil is now the heat absorbing coil extracting heat from the outside air and the indoor coil is the heat dissipating coil giving off heat inside the home. |
| Heat Pumps Come In Various Efficiencies,Sizes An Capacities Heat Pumps have their capacity rated in British Thermal Units or (BTU) the same as Air Conditioners.. Generally speaking, a BTU is the amount of heat required to raise the temperature of one pound of water 1 degree Fahrenheit. In heating and cooling terms, 1 "ton of cooling" equals 12,000 BTU. What Do These Stand For? BTU / SEER / HSPF / EER /COP Heat Pumps have several ratings to consider; before making a decision on the best system for you be sure and consult with a qualified heating and cooling contractor like Harding Heating and Cooling to make an optimal decision. Some of the most important ratings are_ Seasonal Energy Efficiency Rating (SEER) for cooling. _ Heating Seasonal Performance Factor (HSPF) for heating_ Energy Efficiency Rating (EER) for both or Coefficient Of Performance (COP). Current guidelines require all Heat Pumps to be a minimum 13 SEER or more. If you purchase a Heat pump be sure and get the highest SEER to fit your budget. The higher the SEER rating above the basic 13, the less you will spend to heat and cool your home. |
