DC fan manufacturer Chengda found from market research that many mechanical equipment, household appliances, electronic products, etc. will have large or small failures caused by untimely heat dissipation. As a result, work efficiency is slowed down, and it also leads to partial loss of individuals or businesses. We have summarized some effective judgment methods, hoping to help friends in need. The fan coil unit is also related to the effect of heat dissipation. Let's take a look at it together:

The DC fan coil is the end device of the air conditioning system. Its working principle is that the air in the room where the unit is continuously recirculated, so that the air is cooled (heated) after passing through the cold water (hot water) coil to keep the room temperature constant. Fan coil units are widely used in hotels, office buildings, hospitals, commercial and residential, and scientific research institutions. In order to meet the design selection of different occasions.

The types of fan coil units are: horizontal concealed fan coil unit, horizontal exposed fan coil unit, vertical concealed fan coil unit, vertical exposed fan coil unit, cassette two-outlet fan coil, cassette four Air outlet fan coil unit and wall-mounted fan coil unit, etc.

The selection of fan coil units is a key issue. It is a common practice in the design of air-conditioning systems to select fan coil units according to the maximum cooling load of the air-conditioned room, and its purpose is to ensure the room temperature during peak load. 

In fact, most of the time when the air-conditioned room is running will not be at peak load, resulting in excess cooling capacity, and switching to medium and low-speed operation to reduce cooling output, thereby maintaining the thermal balance of the room. When selecting a fan coil unit, in addition to the cooling capacity to meet the requirements of calculating the cooling load, it is also required to meet the matching of its sensible heat and latent heat to meet the requirements of the room heat and humidity ratio; the air volume must meet the supply air temperature difference, ventilation times and airflow organization and other usage requirements.

From the above, we can conclude that if we want to prevent unnecessary losses caused by the unexpected failure of the cooling fan, we must improve the design. In this way, the ability to be criticized is fundamentally eliminated and a fundamental change is achieved.
