Air Source Heat Pump

What is an Air Source Heat Pump?

An air source heat pump is a type of heat pump that can absorb heat from the outside of a building and uses a vapor compression cooling process and similar equipment to air conditioners, but in reverse. The heat from an air source heat pump is absorbed with a low-temperature fluid. This fluid then passes through a compressor where its temperature increases, then it transfers the heat to connected radiators, underfloor heating systems, hot air convectors, and domestic hot water circuits, and continues to operate in a continuous loop. It is divided into two types.

Monoblock Air Source Heat Pump; consists of a single unit and does not require gas or any other adjustments afterwards, hydraulic unit assembly is done according to the system structure of the heat pumps. However, there is no gas connection between the indoor unit and the outdoor unit.

Split Air Source Heat Pump; consists of an outdoor unit and an indoor unit, a copper pipe connection is made between the indoor unit and the outdoor unit, and it operates in this way.

How Does an Air Source Heat Pump Work?

The air source heat pump absorbs the outside air and evaporates the heat it transfers to the energy pool when exposed to the cooling fluid in the evaporator. In this step, the temperature is raised to the required level. The high-temperature high-pressure gas enters the condenser where the energy is transferred to the distribution medium. The cooling vapor is cooled and turns back into a liquid state. This liquid is sent to the expansion valve. The cooling fluid turns into a low-pressure, low-temperature liquid ready to enter the evaporator. This process continues to operate in a closed loop. This heat is then used to heat radiators, underfloor heating systems, or hot air convectors and domestic hot water in your home.

What is the Operating Principle of an Air Source Heat Pump?

The air source heat pump has three internal cycles, they are as follows:

Heating Cycle: Providing thermal energy to the building

Cooling Cycle: Removing thermal energy from the building

Defrost Cycle: Removing frost formation on the outdoor coil

Heat pumps produce carbon dioxide and consume electricity during operation. Electricity generation results in a significant amount of greenhouse gas emissions due to the combustion of fossil fuels. Therefore, in order for the heat pump to be entirely based on renewable energy sources, the electricity it uses must be produced using renewable energy sources such as solar or wind energy. An air source heat pump is a pump that carries the necessary energy for heating from the air to the system inside the building. An air source heat pump is a type of heat pump that can absorb heat from the outside of a building and uses a vapor compression cooling process and similar equipment to air conditioners, but in reverse.
