With the improvement of people's requirements for the air environment, the use of fresh air units such as card fan coil units, fans, heat exchangers, etc. has been actively concerned by everyone. When using card fan coil units, card fan coil units must do a good job in cleaning card fan coil units. Let's take a look at it in detail:
The cassette fan coil is responsible for the important mission of transferring the cold heat of cold and hot water to the air passing through the coil. In order to ensure high efficiency heat transfer, the surface of the cassette fan coil must be kept as smooth as possible. However, since the cassette fan coil is generally equipped with coarse-effect filters with relatively large holes, dust will inevitably pass through the filter and adhere to the pipe or rib surface of the coil when it is first used.
If it is not cleaned in time, the amount of heat exchange between the cold and hot water in the card fan coil and the air flowing out of the coil will be reduced, so that the heat exchange efficiency of the card fan coil cannot be fully exerted. If there is a lot of dust attached, and even some air passages between the fins are blocked by the fan coil, the air supply volume of the card fan coil will be reduced at the same time, further reducing its air conditioning performance.
The cassette fan coil is the ideal end product of the central air conditioner, which is used to exclude the water and gas generated during the use of the air conditioner. Therefore, it is necessary to do a good job in protecting the cassette fan coil to prevent water leakage.
1. After the cassette fan coil is transported to the site, measures must be taken, properly kept, neatly stacked, and rain and snow protection measures should be taken.
2. During winter construction, under the condition that the temperature of the non-heating environment is lower than 5 ℃, the water must be discharged immediately after the hydraulic test of the cassette fan coil to prevent the equipment from freezing.
3. The installation and construction of the cassette fan coil should be carried out with the installation, and the finished product protection should be paid attention to when crossing with other types of work to prevent damage.
4. After the installation of the cassette fan coil, protective measures should be taken to protect the installed equipment and ensure cleanliness.
The cassette fan coil is remotely controlled by a microcomputer. The rotation speed of the fan motor can be set to high speed, medium speed, low speed and the on and off time of the full-automatic air conditioner. The circular heat exchanger is designed with cassette fan coil. The air outlet is uniform. The vortex fan supplies four-dimensional air to maintain uniform and comfortable temperature. The vortex fan strongly absorbs dirty air and can be ventilated indoors and outdoors to make the indoor air fresher and more fresh and natural. The control mode is optional, remote controller, wire controller, thermostat, ordinary three-speed switch, reserved output interface, convenient for users to connect electric two-way valve and realize centralized control function, convenient for centralized management of large projects, reserved ~ 220V output interface, convenient for users to connect electric two-way valve, making it more convenient to control the unit.
The card-type fan coil has high refrigeration (heat) capacity, low noise, three-speed electromechanical conditioning air volume to meet the use requirements, high-quality hot-dip galvanized plate, high-quality copper tube and aluminum fin are selected as a whole, the card-type fan coil fan network is compiled, the water receiving tray is integrally molded, the heat preservation adopts the integral pressure sticking process, the fan coil has no worries about condensed water, has exhaust and water draining functions, and ensures full heat exchange and prevents pipe freezing crack, the surface cooler is made of high-quality copper tube and high-efficiency aluminum fin by mechanical expansion tube processing.
As the terminal equipment of central air conditioning, the card fan coil has been in China for more than 40 years, but many people still have a lot of confusion about the card fan coil. How to determine the model of the card fan coil, here is the air conditioning editor for you.
At present, the national standard codes of card fan coil units implemented in our country, such as FP-68WA,FP is the pinyin code of card fan coil units, 68 is the air volume model, and 68 times 10 equals 680 m3/h.
Many imported brands of card-type fan coils adopt English nominal, such as national standard card-type fan coil FP-68WA, while English card-type fan coil is FC400 or FC04. In case of such a situation, it is suggested to multiply the model by 1.7 to convert it into national standard, such as 400 model * 1.7=680.
