What is the pump in the furnace?

The furnace pump is part of the category of machines called heat pumps. The heat pump is a device that uses mechanical work to move heat from one place to another. Most heat pumps move heat from the area of ​​relatively low temperature to a high temperature area. The pump in the furnace is a type of heat pump that works in this way for heating or cooling the house. The pumps in the furnace use a closed system that circulates refrigerant gas, as well as the air conditioning air conditioning. The difference is that the flow of refrigerant in the system can go either in two ways. Cold or cold air still contains some heat and this heat moves from the outside inside the house. The part of the system that is exposed to the external air consists of coils such as those on the back of the refrigerator. Thecrews can sometimes be collected by ice during cold weather because they are located at a point where the heat is pulled out of the air. Whatever accumulates on the coils, it is periodically melted by pump.

6 Most pumps in the furnace are electric, but use very little energy compared to the air conditioner or furnace. This is because the pumps in the furnace simply move the heat rather than generate. More efficient furnace pumps can be up to four times greater than the amount of energy they consume.

Energy efficiency is the main advantage of pumps of the furnace compared to other methods of heating and cooling. The main disadvantage is that in the climate with very warm summer, very cold winters or both, the furnace pump cannot move sufficient heat to the intention of the intention of comfortable internal temperature.

various refrigeres can be used by oven, depending on when it was made. Up to 90 years were common refrigeres in the furnace and elsewhere chlorofluorocarbones (CFC). The production of some CFC was interrupted in 1995 due to new scientific evidence that they could cause exhaustion of atmospheric ozone. One widely usedAn anise type of spare refrigerant is the Hydrofluorocarbon family (HFC), which are safer but less efficient. Other substitutes include liquid ammonia, propane and carbon dioxide under pressure, especially since 2001.
