Bathroom is a room in which changes in humidity and temperature levels regularly occur. They negatively affect the biological background, which is manifested in the development of fungus and mold. The main way to deal with such processes is to install a fan with a humidity sensor. For the bathroom, special models of the device are available, provided with protected cases and remote controls.
The principle of operation of the device
The operation of the fan is controlled by a special switch, the commands to which come from the humidity indicator (sensor). Some models are provided with a timer with an option to turn off the delay - on average from 1 to 30 minutes. The humidity detector, in turn, can be configured for a light-optical response, in which the fan willautomatically turn on and work for a certain period of time after each turning off the light in the bathroom. When choosing a bathroom fan with a humidity sensor and a timer, it is important to pay attention to the ranges in which it can be automatically controlled.
Standard humidity corridor ranges from 40-100%. If the actual current humidity coefficient in the room exceeds the set optimal value, the device will start working until the microclimate condition returns to normal. In this standalone mode, the fan will function regardless of whether the light is on or the timer is on.
Design
The base for the case is usually made of high quality plastics like moisture resistant ABS alloy. It is mandatory to have splash-proof panels, which in some devices can be replaced, focusing on the textured design to match the interior. The working filling of a bathroom fan with a humidity sensor can be performed in two versions.
- Axial design. Mechanism with a propeller located on the central axis. Accordingly, in the process of torsion of the blades, the air flows move in the axial direction. Such models are characterized by simple design, quiet operation, as well as high throughput.
- Radial construction. In propellers of this type, the blades attached to the axis have a shape bent at a certain angle. The working mechanism is housed in a metalcasing, and in the process of movement, air flows move around the body in a radial direction. The advantages of this design include high power, but it also causes noisy operation.
As for the power supply, typical models operate from a conventional household network. The capacity of a 220V humidity sensor bathroom fan is about 100m3/h at 15W.
Reviews about the model Electrolux EAFM-120
Budget, but quite productive device costing about 2 thousand rubles. The device has an impressive air duct diameter (120 mm), provides ventilation intensity up to 195 m3 / h and has a power of 20 watts. Users note the advantages of the built-in check valve, which does not allow debris and unpleasant odors into the room. The performance of the bathroom fan with the EAFM-120 humidity sensor also does not cause any complaints - the mechanism functions properly at peak loads without slowing down. There are complaints about the plastic molding of the body, but in the front part it can be replaced with a panel made of another material with similar parameters.
Reviews about VENTS 125 Quiet ТН
Offer of the middle price category up to 3 thousand rubles. The duct diameter is 125mm and the capacity is 185m3/hour. At the same time, the noise level is slightly higher than that of the previous model - 32 versus 31 dB. Also to the weaknesses of thisfan, users attribute a narrow threshold of automatic operation in the range of 60-90%, the absence of a light switch sensor (only optional) and a high lower level of activation by a timer from 2 min. What compensates for these shortcomings? Positive impressions are mainly related to the design. In the bathroom, a fan with a humidity sensor 125 Quiet TH can be installed in a variety of ways both in the wall and in the ceiling. Installation is facilitated by a shortened spigot that fits a wide range of ventilation shafts and ducts. A check valve is also provided, which eliminates backflow and minimizes heat loss during propeller operation.
Reviews about the model Soler&Palau SILENT-100 CHZ
The device rather belongs to the premium segment, having wide functionality. At the same time, the productivity of the model is average - only 95 m3 / h. On the other hand, the noise level corresponds to the whisper of a person at a level of 26 dB, which eliminates the slightest sound discomfort during operation. Users themselves indicate the sensitivity of the hygrostat of the device. In reviews of the SILENT-100 CHZ version of the bathroom fan humidity sensor, they emphasize the flexibility of its settings, ergonomics and accuracy of operation at the slightest fluctuations in the microclimate. The advantages of the device include low power consumption - no more than 8 watts. Built to last for 30,000 hours of operation, you can count on years of trouble-free fan operation.
Installationappliance
When choosing a place for installation, you should provide for the possibility of access to the components of the device and the lack of interaction with other climatic equipment. To create conditions for maximum ventilation efficiency without interference, it is desirable to place the device as high as possible - at a level of 2-3 meters, but so that the distance from the ceiling is 20-30 cm. It will not be superfluous to also focus on the maximum capture of the most polluted points in the room. Installation of a bathroom fan with a humidity sensor is carried out according to the following instructions:
- A hole is made in the wall, corresponding to the size of the fan nozzle. It is desirable to avoid possible changes in the design of the pipeline.
- If the air duct brings the channel directly to the street, then it will be important to ensure the slope of the pipe towards the facade so that precipitation does not penetrate the structure.
- Mounting is carried out with complete hardware - screws, mounting brackets or self-tapping screws, depending on the wall material.
Ceiling installation is carried out in general according to the same scheme with the creation of a hole in the ceiling. The main thing is to provide before installation that the outlet channel has an output to the outside, and not to the attic or above-ceiling space.
Connecting the device to the network
After installing the housing, electrical work is carried out. To connect a bathroom fan with a humidity sensor and a timer, it is necessary to prepare the fixing points and the cable entry. Using terminal blocks (must beincluded) the cable is connected to the fan. The main connection circuit is fixed with special fasteners to the device structure. In the course of performing electrical measures, it is important to take into account the compliance of the wiring parameters of the local network. Humidity fans are normally double electrically insulated so grounding is not necessary.
Conclusion
The quality of the fan and the correctness of the sensor readings will depend on the maintenance of the device during operation. Experts advise regularly cleaning its surfaces by removing the outer panel. Maintenance is carried out with a microfiber cloth with mild cleaning solutions without abrasives. In addition, the bathroom exhaust fan with humidity sensor is periodically checked in the draft index.
For this, a special device is used - an anemometer. It reflects the speed of air flow, which should be compared with standard indications. An easier way is to bring a piece of paper to the working panel of the fan, checking its downforce. If during such tests deviations in the operation of the device are detected, then the design is disassembled and maintenance is carried out with repair operations. It is better to trust the service center for such work.
