This paper introduces the use of combined rotary dehumidifier.

System debugging of combined dehumidifier includes debugging of single dehumidifier, joint debugging without consumption load and system debugging. The specific requirements are as follows: Prepare well before commissioning; The electric control and regulation system should be stopped and debugged first; After all the equipment in the system has passed the debugging, the consumption load of joint debugging and debugging shall not be stopped; Continuous debugging of fans and runners shall not be less than.

The dehumidification system with cold (heat) source shall be debugged not less than 8 hours in normal combination, and only the cold (heat) source shall be debugged in the season when there is a big difference between the debugging design conditions; The reliable performance of test equipment and instruments used in debugging should be stable, while the small-scale value accuracy level should meet the requirements of debugging and should conform to the national laws and regulations and metrological verification regulations; Debugging needs to provide materials and reports that remain complete after debugging.

Check whether the models and wiring of various electrical components of the dehumidifier system design circuit can be developed correctly. In order to ensure the safety of personal safety equipment during debugging and learning, before debugging the dehumidifier (in the case of power failure), make sure that the models of various electrical components are selected correctly. Then, check the electrical wiring, make sure all the terminals are fastened, and make sure whether the wiring is correct, the performance of its insulating material and the system as a grounding meet the requirements.

Measure the phase resistance of condenser fan, regenerative blower and wheel motor. The measurement must be carried out at the lower end position of thermal relay or contactor with clamp meter, and the phase resistance and phase resistance value must be measured to see whether it is relatively balanced and the inequality does not exceed the phase resistance.

Let's analyze the working principle of dehumidifier.

Dehumidifier is a very popular household appliance. What is the working principle of dehumidifier? Second, listen carefully. Dehumidifier can remove moisture from the air, and its basic working principle is to make the condensation temperature of moisture low. That is, air is sucked into the dryer after being wetted by the fan.

After passing through the thermal and economic exchanger, the water molecules in the air in China are condensed into water droplets, and the dry air after disposal is discharged outside the machine. This development cycle makes the indoor environmental humidity must be kept at a suitable relatively high humidity. And the dehumidifier is also divided into two parts: internal circulation and external circulation.

The circulating tightening machine in the dehumidifier operates HPHT→ →→→→→→ after the exhaust gas is discharged to the condenser for cooling, it becomes the low-temperature and high-pressure gas which enters the closed low-temperature and low-pressure liquid through the capillary tube for vaporization →→→→→→→→ absorbs heat and then returns to the tightening machine through the evaporator to become the low-temperature and low-pressure gas. This cycle.

External circulation of dehumidifier: under the normal startup condition → through the operation of a fan → moist air is sucked in from the air inlet → through the system evaporator → the evaporator absorbs moisture in the air on the aluminum sheet → becomes a kind of boring air → passes through the design condenser to dissipate heat → blows out from the air outlet.
