Operating principle of Dehumidifier:
1. Internal circulation of Dehumidifier:
Through the operation of the compressor → discharge high-temperature and high-pressure gas from the exhaust port → enter the condenser for cooling → become low-temperature and high-pressure gas → intercept through the capillary → become low-temperature and low-pressure liquid → evaporate and absorb heat through the evaporator → return to the compressor and become low-temperature and low-pressure gas. So it goes back and forth.
2. External circulation of Dehumidifier:
Under normal startup conditions → through the operation of the fan → moist air is sucked in from the air inlet → passes through the evaporator → the evaporator adsorbs the water in the air onto the aluminum sheet → becomes dry air → dissipates heat through the condenser → blows out from the air outlet.
Only by understanding the use precautions and working principles can we do a better job in the daily maintenance of the Dehumidifier during the long-term use of the Dehumidifier in the future。
Dehumidifier is a seasonal product. If it is used properly in daily life, it can not only exert the maximum efficacy of Dehumidifier, but also reduce the failure rate and extend its service life. The following are some methods for accurately using, maintaining and maintaining the Dehumidifier.
1. Let professional staff check the Dehumidifier on schedule: after the dehumidifier has been used for a long time, the electrical circuit and control elements in the unit will be aging to varying degrees, which will seriously cause harm to the unit and human body. Let professional staff check the circuit of the Dehumidifier on schedule, replace the aging elements, and add refrigerant, which can prevent the aging of elements from harming the machine and human body, And it can keep the Dehumidifier in good working condition.
2. If the dehumidifier is not used for a long time, protective measures should be taken: when the Dehumidifier is not used for a long time in winter or outside, the Dehumidifier should be covered with a protective cover to avoid the sun, rain and dust deposition, which may cause problems in cleaning and maintenance in the future.
3. Accurately adjust the set humidity of the Dehumidifier: When users adjust the set humidity of the Dehumidifier, they should set the humidity according to their own sense of humidity, the number of people in the space, the size of the space and other actual conditions. Usually, in a state of less fluid flow such as rest and sleep, when the relative humidity of the room is around 60% RH, the human body will feel more peaceful. The humidity setting is too low. In addition to making people feel dry, because of the large difference between indoor and outdoor humidity and the rapid expansion of moisture, the compressor is frequently started and stopped, which shortens the service life of the Dehumidifier and consumes more energy.
4. Clean the Dehumidifier on schedule: remove the filter screen of the Dehumidifier on schedule for cleaning, which can effectively improve the dust removal effect of the Dehumidifier and improve the ambient air quality. Cleaning the radiator of outdoor unit on schedule can effectively improve its heat transfer coefficient and efficiency, and improve the working efficiency of Dehumidifier.
Placement of Dehumidifier: place the Dehumidifier in a place with good ventilation, to avoid that the dehumidifier cannot reach the required dehumidification effect due to poor ventilation in a dead corner.
Maintenance of Dehumidifier: clean the filter screen at least once every two weeks. Never place the Dehumidifier sideways or upside down during storage to avoid damaging the compressor.
Use of Dehumidifier:If the Dehumidifier is moved over a long distance or violently, it is advisable to keep the machine body still for 2-3 hours before connecting it to the power supply to avoid damage to the compressor. Before operation, the doors and windows should be closed to prevent moist outside air from entering the room and affecting the dehumidification effect. If there is no need to use it, try to reduce the times of opening and closing the doors and windows.
The condenser should be cleaned regularly and kept clean. The Dehumidifier shall be placed in the central position of the room. The air inlet and outlet of the Dehumidifier shall not be blocked by obstacles, and the air filter network shall be cleaned. When the ambient temperature is lower than 15 ℃, the water droplets attached to the evaporator surface will freeze and weaken the effect of the Dehumidifier. If the ambient temperature exceeds 40 ℃, the pressure in the system will increase and overload the compressor. At this time, the overload protector should cut off the line, otherwise the compressor motor will be damaged. Therefore, the optimal operating temperature range of the Dehumidifier is 5 ℃~38 ℃. The microcomputer controlled Dehumidifier has the Auto-defrost function, and the operating temperature range can be 5 ℃~40 ℃. If the humidity in the air is below 30%, it is too dry and uncomfortable. Therefore, a reliable humidity controller controls it to maintain a range of 50% to 60%. When using, close the doors and windows as much as possible to achieve dehumidification effect indoors. The body should be placed flat and not tilted or overturned to avoid machine malfunction or abnormal noise. The water storage in the Dehumidifier is too full. To avoid overflowing the dirty and wet ground, when the machine body must be transported during operation, please unplug the power cord plug first, and then pour out the water in the water storage bucket.
