Fan coil design is widely used in today's refrigeration (heating) systems. It has the characteristics of small size, easy installation, and high design flexibility. However, how to choose the best solution according to the actual needs of customers and the design drawings should fully consider the following points:
1. Check of cooling capacity
The cooling capacity calculation method under actual operating conditions is: cooling capacity = cooling capacity × average operating time per unit time. However, in most cases, the cooling capacity will be calculated using the nominal value. Combining the actual engineering and comparing the two calculation methods, we can find that it is not that the higher the nominal cooling capacity is, the better. If the high cooling capacity unit is simply selected, there will be waste of resources and increased costs. Therefore, the cooling capacity value can be used as one of the key considerations for coil design selection, but it is not the only key to be considered, and the influence of other factors should also be taken into account.
2. Check of air volume
The check of the number of air changes is mainly carried out with reference to the actual requirements of the room. In daily life, we often feel that the air-conditioned room has a peculiar smell and is very stuffy. If this happens, the air volume check has not been handled properly. The size of the supply air temperature difference affects the number of air changes. An increase in the number of air changes will reduce the supply air temperature difference. In this way, the air quality in the environment will be better and the people in the house will also feel comfortable. The theoretical test condition of the nominal air volume is that the pressure difference between the water and air inlets is zero. However, there will be some deviations during the test. Therefore, we should consider a certain amount of air volume margin in the actual determined air volume value. In engineering, there is a certain amount of air volume The air volume margin of the amount is recommended to be 20%-30%.
3. Way of sending and returning air
Whether the design of the air supply and return air method is reasonable or not directly affects the uniformity and stability of the temperature field and velocity field in the entire room, that is to say, affects the quality of the cooling effect of the air conditioner. The external static pressure is an important parameter value that affects the wind speed in the coil. If the static pressure outside the machine is too low, it will cause the air volume to drop. There is a certain amount of deviation between the design of air supply and return and the actual working condition. Therefore, it should be analyzed in detail to select a fan coil model with suitable air volume and wind speed.
4. Other factors
In addition, the noise factor of the fan coil is also a problem that cannot be ignored. There are certain restrictions on the noise index in the project, and the noise value should not exceed 40 decibels. If the noise value of the fan coil is too large, consider installing a muffler to reduce the noise value, and the resistance value of the muffler should be controlled within 10P.
In the air conditioning system, the fan coil is an indispensable component, which can regulate the indoor air, allowing users to enjoy a more comfortable and clean living space. The advantages and disadvantages of fan coils exist at the same time, which is the same for all things, so users need to look at it dialectically to see if it meets their own needs. When selecting and installing the fan coil, you need to pay extra attention to it. Professionals are required to install it to ensure the effect of future use.
