Split fan coil heating is an air conditioning system that offers an efficient and versatile solution to keep your spaces at an optimal temperature all year round. By harnessing the energy contained in the air, this system provides both heating and air conditioning, providing comfort at any time and in any place.
Basic principles of aerothermal energy
Aerothermal energy is based on the principle of heat transfer, where the heat present in the outside air is used to heat the inside of the rooms. By making use of an air-to-air heat pump, the aerothermal system achieves heat transfer through a refrigerant circuit consisting of an evaporator and a condenser. In this way, an efficient and sustainable process is achieved that contributes to energy savings.
Components of an aerothermal system with split system
The split system consists of two main elements: the evaporator, located inside the house or premises, and the condenser, located outside. These two components are interconnected by a refrigerant circuit, which allows heat exchange between the indoor and outdoor air. In addition, it has a compressor that is responsible for raising the temperature of the refrigerant fluid to generate heat and cool it to provide air conditioning.
Operating mode in air conditioning
When the split-split fan coil system is in air conditioning mode, the heat pump transfers cool air into the room and exhausts warm air outdoors. This is achieved through changes in the heat and state of the coolant circulating in the circuit. The compressor compresses the gas, increasing its temperature, and then the condenser cools the gas, which becomes liquid, releasing the heat to the outside. Finally, the refrigerant fluid in its liquid state gives up heat to the outgoing air through the evaporator, thus cooling the space.
Heating mode of operation
In the case of heat generation, the cycle is reversed by a four-way valve. The compressor compresses the gas, raising its temperature and transferring heat to the air inside. Subsequently, the liquid refrigerant is converted to gas through the expansion valve, causing a decrease in pressure and a drop in temperature. In this way, the evaporator cools the gas, transferring the cold to the outside air and providing space heating.
