ecodan air source heat pump technology explained

• Green Air exclusively use the Mitsubishi Ecodan air source heat pump unit. Here is an explanation in a bit more detail of how they work;
• The advanced heating technology used in an Ecodan heat pump make them ideal for use in the UK’s ambient temperatures. The technology is similar to a standard refrigerator, using a vapour in the refrigeration cycle. The main components in a heat pump are the compressor , the expansion valve and 2 heat exchangers (an evaporator and a condenser).

1. Refrigerant in the evaporator is colder than the heat source. This causes the heat to move  from the heat source (in this case the outside air) to the refrigerant, which then evaporates.
2. The vapour moves to the compressor and reaches a higher temperature and pressure.
3. The hot vapour now enters the condenser and gives off heat as it condenses.

The r^efrigerant then moves to the expansion valve; drops in temperature and pressure; and then returns to the evaporator.

What makes the Ecodan air source unit uniquely efficient?

Inverter-driven technology

At the heart of an Ecodan air source heat pump is a modern, inverter -driven heat pump compressor . This converts free heat energy from the air by pressurising it to achieve higher temperatures suitable for heating. The inverter control regulates the system so that heat output adjusts to match the exact output required. This means that the system will only consume the exact  energy needed at any given time, thereby increasing efficiency further.
