Product Description
Connaught Beijing Heng Xin Electrical and mechanical equipment Technology Development Company Limited is a multi-year commitment to install central air-conditioning refrigeration equipment, energy saving, operation, repair, maintenance, custody of central air conditioning units and ancillary terminal equipment cleaning services, industrial equipment cleaning services company.
Fan coil units rely mainly on fan forcing function, allowing air to pass through the surface of the heater is heated, thereby strengthening the radiator and air convection heat exchanger, the ability to rapidly heat the air in the room. Fan coil air conditioning system terminal device, its working principle is the unit continuously recirculated installed wind pipe room where the air, allowing air to pass through the cold ( hot ) coil cooling ( heating ), is to keep the room temperature constant. Usually, the fresh air unit processing into the room, to meet air conditioning room fresh air needed. However, due to this heating method based on the convection heat transfer, causing indoor reach the best level of comfort, it is only suitable for people with shorter retention time place, such as: office and hotel, but not for ordinary residential. Due to increased wind machine, improve the production cost and operation cost, equipment management and maintenance is also more complex.
Fan coil control by local control scheme, simple control and temperature control two. Simple control: using three speed switch direct manual control fan three speed conversion and start and stop. Temperature control: STC series controller according to the set temperature and actual temperature detection, arithmetic, automatic control of STV series electric two / 3-way valve open / close; fan three speed conversion. Or directly controls the fan three speed conversion and start-stop, through the control system of water or air to achieve the purpose of constant temperature.
Fan coil as the end of the central air-conditioning equipment, its quality decides the effect of indoor air conditioner. Main properties of cold (hot ) is a quantity security, wind protection, noise numerical ratio, condensed water leakage and electrical, sheet metal design and so on. Central air conditioning host after cooling to 7 degrees of water to the fan coil, in fan coil units inside the exchange after becoming 15--16 of cold air, so the room temperature decrease. However, the dust particles in the atmosphere, in the long-term, pumping air under the action of wind machine, aluminum fins of the dusty dirt, this aspect influences the chilled water and hot air heat exchange air temperature drops affected; on the other hand also affects the after heat exchange of cold air cooled send out, causing the air conditioner and the room is still not cold phenomenon. Therefore, central air-conditioning use over a period of time (usually 1-2 years ), it must be on the fan aluminum fin cleaning, in order to solve the defects.
Cleaning fan finned aluminum process must first remove blower motor and impeller, can give to motor, capacitor is burned for inspection. Cool in the summer, due to the condensation water, in the tray into the condensed water drainage pipe, easy producing bacterium and algae group, jam condensate drain, so deal with the tray for cleaning and sterilization and other maintenance work. The cleaning fan coil collecting disk, sterilization and condensate pipe dredge, regularly in fan coil collecting tray placed fan-coil disinfecting tablet, can prevent bacteria, algae breeding because of pipe blocking. At the same time on the fan coil of fan impeller, volute and motor, shaft and dust. Fan coil after cleaning, ventilation quantity increases, central air conditioning effect is good, indoor air quality, noise reduction, electricity reduction, condensation of water flow.
Main process includes maintenance, cleaning (cleaning, sterilization, fan coil cooling device removing algae ), fan coil unit and air inlet and outlet of maintenance. Specific cleaning process is as follows: 1, return air filter cleaning disinfection
In 2, sending wind system of sterilization.
In 3, fan coil cooling device, used for central air-conditioning cleaning agent for cleaning, cleaning, sterilization. Maintain ventilation Chang Shun
In 4, the coil of fan impeller, volute, motor dust cleaning, motor shaft gas.
In 5, butt plate, filter for removing sludge water, impurities, clean, keep smooth water flow
6, out of the air gate clean.
7, check the water pipes are connected firmly
8, check the insulation is good
9, check whether the valve is in water leakage
In 10, fan coil below do not install fluorescent lamp facilities
