The air source heat pump heating system has three types at the end: floor heating, fan coil unit and radiator. From the use experience, floor heating is undoubtedly the most comfortable, because the heat is emitted from the bottom to the top, which is in line with the way of health, but the requirements for decoration and maintenance of floor heating are high. Compared with floor heating, fan coil units also have advantages in heating systems, such as short startup time, energy saving, system simplification, design and installation, simple control, etc.
Vertical open mounted fan coil
Because the fan coil unit is a forced convection radiator, opening the fan coil unit can make the room temperature reach the design parameters in a very short time. After the fan stops, its heat flow loss is also small, so it is very suitable for most office workers' families and commercial offices with intermittent heating requirements. If there is no one at home during the day for office workers, the indoor temperature can only be kept at ordinary temperature, and the night rest can only be kept at bedroom temperature; The office building needs heating during the day and not at night.
The water resistance of the heat exchanger of the fan coil unit is greater than that of the radiator, so there are many different path systems in the system design. Compared with the radiator system, it is not easy to have hydraulic imbalance, and the indoor water system design should be simplified. The water system design is more simplified, which is also an advantage of fan coil unit compared with other heating methods.
Horizontal concealed type fan coil unit
The floor heating system involves pipe laying, pipe material selection, end system design and other factors, and the layout is very complex, requiring rich installation and practical experience. However, the layout of fan coil unit heating is more flexible. According to different types of fan coil units, there can be a variety of layout methods. For example, the horizontal concealed type can be installed in the ceiling of small residential corridors, the vertical open type can be installed on the ground, and the wall mounted type can be installed on the wall. For different building forms, the installation form of fan coil units can be selected according to their own characteristics.
The water circuit system of fan coil unit is relatively simple, so it is enough to ensure that there is hot water in the pipeline. The fan coil unit does not require high water supply temperature. Generally, the water supply temperature does not exceed 60 ℃. The heat source with a temperature above 40 ℃ can ensure the effective operation of the fan coil unit system, while 40 ℃ hot water is easy to achieve for the air source heat pump heating system.
