Introduction: Today, the small rabbit to introduce you to the relevant knowledge about the fan coiler, for a lot of friends still do not quite understand the fan coiler. Bunny first give you a brief introduction, in fact, fan coiler is the central air conditioning an ideal end product. But at present, with the continuous development of technology, the application of fan coiler also continues to become very wide. Fan coiler is currently in the office, medical surface are applied, the next rabbit will give you a fan coiler knowledge.
A, fan coil working principle
Fan coil mainly rely on the fan's coercive effect, so that the air through the heater surface is heated, thus strengthening the radiator and the air convection heat exchanger between the room can be quickly heated air. Fan coil is the end of the air conditioning system device, its working principle is the unit constantly recirculation of open air duct.
The air in the room where it is located is cooled (heated) after passing through the cold water (hot water) coil to keep the room temperature constant. Usually, the air is sent into the room after being processed by the fresh air unit to meet the need of fresh air volume in the air-conditioned room.
Two, composition
Central air conditioning fan coiler according to the number of rows can be divided into: two rows of tubes, three rows of tubes; there are two control and four control points: two control of the ordinary fan coiler in the summer to go to the cold water refrigeration, winter to go to the hot water heating;
The four-control fan coiler is more used in some of the more luxurious places, you can go to the same time, both hot water and cold water, that is, you can be According to the needs of some rooms cooling, some rooms heating. Two rows of pipe is a pipe into the cold water in summer, a pipe out of cold water, a pipe into the hot water in winter, a pipe out of hot water; three rows of pipe is a pipe into the water, a pipe into the cold water, a pipe into the hot water, at the same time a pipe out of water.
Three, environmental requirements
1, fan coiler set of inlet cold water temperature should not be less than 5 ℃, otherwise it may cause condensation unit; inlet hot water temperature should not be higher than 80 ℃ (commonly used? 60 ℃), otherwise it may cause the unit heat exchanger copper pipe corrosion.
2, ? Suggested operating ambient temperature of fan coiler unit for cooling: 16 ~ 36 ℃, heating: 10 ~ 30 ℃; air relative humidity ≤ 90%.
3,? Fan coil unit is only used as a comfort air conditioning, do not use for special occasions.
4.? Do not install the fan coiler in areas with corrosive gases.
After some of the above, I believe you have a certain understanding of the knowledge of the fan coiler. It is recommended that we should be used during the regular cleaning, try to reduce the wind resistance of the fan coiler, in order to facilitate long-term energy saving, but also for system maintenance, you can lengthen the service life of the fan coiler. There are more about the fan coiler content you can carry out a detailed understanding of the knowledge of the fan coiler, it will be the first to speak here.
