What is a cassette fan coil, usually we call it a wind plate, figuratively speaking, it is the air outlet of the central air conditioner, which is hidden in the local ceiling of the living room or room, and transmits a steady stream of hot and cold air to every corner of the building. So what is the cassette fan coil in the selection, usually we call it a wind plate, figuratively speaking, it is the air outlet of the central air conditioner, it is hidden in the local ceiling of the living room or room, and transmits a steady stream of hot and cold air to every corner of the building. So what problems should we pay attention to in the selection of the cassette fan coil.
1, in the selection of card type fan coil refrigeration unit, is the design of the preheating load and unit sensible heat load matching, in most cases, the coil has enough latent heat capacity, can meet the design needs, such as the use of outdoor air is the corresponding repair of its load and calculation formula: water temperature rise = air temperature rise.
2, heating: usually according to the selection of refrigeration units, heating capacity is sufficient, the heat is in accordance with the same water flow to select, fan coil that is to use the inlet water temperature to meet the indoor heating load, indoor heating load, inlet air temperature.
3. Refrigeration: indoor preheating and cooling load, total indoor heat and cooling load, inlet air temperature, inlet water temperature, air volume.
The second step of card type fan coil selection: determine the unit specifications, water volume, required water temperature and pressure drop and other parameters.
1, clear fan motor bearing whether the use of oil or oil-free shaft pump, if the use of oil-free shaft pump, the use of consistent in accordance with the provisions of regular refueling.
2. Make clear the left or right outlet direction of the connecting pipe of the selected unit (related to pipeline layout, etc.).
3. Hot water in winter, the water temperature generally does not exceed 60 ℃, which can reduce scaling, and at the same time reduce the alternating effect of cold and heat, which weakens the expansion force of the expansion tube and affects heat transfer.
4. Pay attention to the heat preservation measures of the effluent to avoid condensation and defacement of indoor buildings during summer use.
5. A bleed valve is set at the highest point of the unit coil.

The selection of card fan coil is relatively simple, and the price of card fan coil is not expensive, and the maintenance is relatively convenient. However, choosing the right card fan coil can undoubtedly add icing on the cake to the operation of the central air conditioning system, making home life like a fish in water, pleasing to the eye, installation design making home more beautiful, home central air conditioning, bringing people a healthy and happy family life with high technology, the luxury and beauty of its appearance are incomparable to those of ordinary air conditioners. Their appearance design is streamlined, and the corners of the air conditioner are designed into curved arcs. The color LCD screen and the striped or wavy air inlet and outlet are matched together to form a beautiful pattern. The whole appearance design is artistic, and the appearance color is mainly Milky White, which is noble and elegant, which can be used as a luxurious decoration, regardless of the distant view, the appearance of the modern family central air-conditioning gives people an artistic mood.
Generally, the pipeline part of the cassette fan coil system connected with the coil is equipped with special-shaped pipe fittings such as valves, filters and hoses on the project site. The heat preservation is not easy to be dense, and the condensate dripping is easily caused by frequent disassembly in daily maintenance. In the practice of the actual fan coil in the project, the method of sloping the local pipeline of water supply and return to the coil side can be adopted to prevent and remedy.
The poor drainage of condensate is mostly manifested as water overflowing from the condensate water receiving tray of the cassette fan coil. During the operation and use of the air conditioning system, local stress is too large or the support and hanger are invalid, which is easy to cause slope change or local water storage, which is easy to cause condensate water overflow. It is necessary to strictly control the slope of the water pipe during installation, dredge the drainage pipeline and control the reasonable distance with other pipelines, and check the installation fixing points of supports and hangers to prevent deformation and falling off. During the construction process, some people think that as long as the water enters from the highest point of the condensate pipe network, the water can be discharged from the lowest point. However, it is not enough to discharge water only, and the same amount of water should be ensured. Otherwise, there will be local water storage problems. The card fan coil air conditioner is also easy to accumulate impurities and breed bacteria moss, and plug the pipeline for long time, this kind of problem must be strengthened construction management, and it is difficult to find and deal with it after the condensate pipe is insulated.
