How does an aerothermal system work?
The operation of aerothermal energy basically consists of a heat exchange using an aerothermal heat pump. The heat pump takes thermal energy from the air and transfers it to a refrigerant liquid through a heat exchanger. This liquid becomes gaseous and reaches a compressor where it increases the pressure and consequently the temperature of the refrigerant gas. This increase in temperature is used to heat a flow of water that transports the heat to the inside of the house through the corresponding emission system (underfloor heating, low-temperature radiators, fan coils, etc.). This process can be reversed to extract heat from the inside, thus also becoming a cooling system.
