What is a heat pump?
A heat pump is an energy-saving technology that transfers heat without needing to generate it.
How Heat Exists in the Air
There is heat in the air even in places generally considered cold, such as the North and South Poles. However, because the amount of heat is small, these places feel cold.
When the amount of heat is large, the temperature is high. When the amount of heat is small, the temperature is low.
A heat pump is a technology that controls temperature by transferring heat.
For example, because heating is done by moving heat from outside into the room, only a small amount of electricity is needed. This delivers energy savings.

Refrigerant Heat Carrier Diagram (Heat Medium Circulation)
1. Heat is carried by the refrigerant.
Refrigerant is the medium that carries heat. An air conditioner transfers heat by circulating refrigerant between the indoor and outdoor units.
Refrigerant is essential to an AC and acts as its lifeblood.

2. Heat transfer (Laws of Thermal Physics).
The laws of physics state that heat moves from an area of higher temperature to an area of lower temperature.
For example, when a hot spoon is placed on a cold spoon, the cold spoon becomes warm. Heat is transferred from the hot spoon to the cold spoon. Heat transfer stops when both temperatures become equal.

3. Taking advantage of the physical properties of heat, the refrigerant carries heat, and the refrigerant's state changes in the process to provide heating and cooling.
Heat collected from outdoors is transferred indoors.
- The refrigerant absorbs heat from air
- The refrigerant releases heat to air
