Air-to-air heat pump: Advantages, Installation, Maintenance
Easy to install, at a reasonable cost and usable all year round, the heat pump has the additional advantage of using a free and renewable resource, air.
The principle of the air-to-air heat pump
The principle of a heat pump or "heat pump" is to capture the calories from the air outside a building to restore them inside. Unlike the air-to-water heat pump, the heat is returned directly to the air, and not to a water network.
Outside the home, a unit captures the ambient air, in order to draw the heat from it into a refrigerant fluid, like in a refrigerator. This turns into vapor, which a compressor will raise in temperature. The steam then condenses, and transmits its heat to the indoor units of the house, the fan coils: they will redistribute the heat in the air of the house. A pressure reducer then reduces the pressure, before the fluid passes through the exterior for a new cycle.
The air-to-air heat pump is not connected to a central heating system: it remains a good backup solution. It cannot produce domestic hot water.
The different components of a heat pump operate on electricity.
The advantages of the air-to-air heat pump
With a free and renewable energy resource, the air-to-air heat pump is relatively economical, even considering the electricity requirements to operate the system. It is a profitable solution, and its cost to purchase - very affordable - is quickly amortized. Today, the air-to-air heat pump remains the cheapest of the heat pumps.
The air-to-air heat pump can be used all year round! Adaptable to winter heat needs, it can also be used in summer to cool the air when the outside heat rises: its system can be reversed, and it can reject hot air from inside the house. House.
Installation and maintenance of the air-to-air heat pump
The lower the temperatures, the less efficient the heat pump will be: the heat pump prefers mild climates.
Unlike the air-water heat pump, the installation of the air-air heat pump does not require any connection to a water network - radiators or underfloor heating. It is then often installed in addition to electric heaters.
On the garden side, on a courtyard, balcony or terrace, the outdoor unit must be installed on a well-ventilated facade of the building, the air must circulate easily. In addition, the installation must take into account the passage area, exposure to bad weather and the sun, the noise of the pump and the proximity of the neighborhood: to meet the standards imposed, it is advisable to entrust the installation of its heat pump to a qualified professional. It may be necessary to provide an acoustic insulation solution. Inside, you can place several units according to your needs.
For balanced consumption, optimal comfort, good quality ambient air, and greater safety, do not forget to have your heat pump checked once a year. Your heating engineer will be able to check the operation of the system, the condition of the filters, as well as the tightness of the refrigerant network.
