Fan coil dust treatment
Filters should be installed at the water inlet of the fan coil unit at the inlet and outlet of the fan coil unit produced by Dezhou Lai Sen Environmental Technology Co., Ltd. When flushing the main pipes of the refrigerant water system, sewage is not allowed to pass through the coils. The highest point of the coiled pipe connection shall be provided with an exhaust device, and the lowest point shall be provided with a drain device. Cassette fan coils are easily clogged when used in the living room. This is mainly due to the presence of water in the cassette fan coils in the guest room. Coupled with the appropriate temperature, it is easy for algae to multiply and grow, resulting in a gelatinous, extremely thick residue that will condense. The water pipe is blocked.
Foreign fan coil manufacturers often place algicides in the water collecting coils of card fan coil units in guest rooms to reduce their harm. We provide high-quality after-sales service to customers and friends to solve the daily use of fan coils. problem. The condensate discharge pipe of the fan coil unit must have a certain slope, and water should not be accumulated in the drip tray. For the installation of fan coil units, please refer to the National Construction Standard Design Atlas 01K403 "Fan Coil Installation". In the guest room, the fan coils often leak water. If the pipes and valves are not damaged, it is usually caused by condensation.
Leakage of water outside the fan coil pipe collecting pan is mainly a thermal insulation problem, which can be eliminated by strengthening the heat preservation; if the water collecting pan is the condensate pipe is not smooth, it is caused by the condensate overflow, the method of dredging the condensate pipe is usually prepared A 4-5 meter long plastic pipe, one end is inserted into the condensate drain pipe, and the other end is connected to the bathroom faucet (a small joint can be made and screwed on the faucet), and the pipe is dredged with the pressure of water, or Purge with a carbon dioxide cylinder. That is, the hose joint is installed at the water inlet and outlet. The soft joint has types such as glue or metal corrugation, which mainly reduces the vibration of the fan coil during operation, and can also buffer the pipe joint or the pipeline due to its vibration.
In order to facilitate the observation of the condensate removal condition of the coil pipe during summer operation, a section of transparent plastic hose should be installed at the exit of the condensate coil, and at the same time, dust, lint, etc. can be removed to avoid clogging the condensate pipe and causing the pan to overflow. . Hose clamps should be used at both ends of the hose to fasten the cables.
The horizontal section of the water inlet and outlet of the fan coil should not be too long. At the same time, a slope of 2 ‰ ~ 3 ‰ should be considered. The aspect can be divided into two cases: the first case is when the inlet and outlet pipes of the fan coil are higher than the main pipe of chilled water (air conditioning hot water) (Figure 2), when the horizontal branch pipe connected to the fan coil is installed, The inlet pipe should be installed against the slope and the outlet pipe should be installed along the slope. Air in the system is removed from the manual air release valve of the fan coil.
The second case is when the main water supply and return water pipe is higher than the water inlet and outlet of the fan coil. An automatic exhaust valve can be set on the main water supply and return pipe to empty the system. When the horizontal branch pipe is installed, the inlet pipe should be installed along the slope, and the outlet (return water) should be installed against the slope. Inside the coil heat exchanger in the fan coil The air can be basically discharged from the exhaust valve of the main pipe.
