Fan coil is the ideal end product of central air conditioning, fan coil is widely used in hotels, office buildings, hospitals, scientific research institutions and so on. The fan will be indoor air or outdoor mixed air through the surface cooler (coil) cooling or heating into the room, so that the indoor temperature is reduced or increased, to meet the comfort requirements of people. How much do you know about the main characteristics of fan coil? Today, we come to understand the fan coil manufacturers together:
1. Working principle of fan coil unit
Working principle of fan coil unit. The fan coil unit is the terminal device of the air conditioning system. Its working principle is that the fan continuously circulates the air in the room, so that the air is cooled (heated) after passing the cold (hot) water coil to keep the room temperature constant. Usually, fresh air is sent into the room through fresh air unit processing, in order to meet the needs of air conditioning room fresh air volume.
2. Structural characteristics of fan coil units
Fan-coil unit body structure is compact, fastening and durable, usually using high quality galvanized plate shell, condensed water plate by molding process, no welding seam, welding spot, in line with the fire insulation material is connected to the water plate. Low energy consumption of fan coil, reasonable match of fan and heat exchanger, three gears adjustable air volume makes fan energy consumption the most economical. Because this kind of heating method is based on convection heat exchange only, and cause indoor not to reach the best comfortable level, it is only used in the place where people stay for a short time, such as office and guesthouse, and is not suitable for ordinary residence. Due to the addition of fans, the cost and operation cost are increased, and the maintenance and management of equipment are also more complicated.
3. Fan coil control mode
Fan-coil unit control mainly adopts local control mode, which can be divided into simple control and temperature control.
