The dehumidifier can achieve a good dehumidification effect, and a large part of it is the role of fluorine, so once it is found that the working ability of the dehumidifier has decreased, it is necessary to check whether there is no fluorine. If so, then charge the dehumidifier with fluoride. How to operate it? Below are the detailed steps.
Before we charge the dehumidifier with fluoride, we must first check whether the machine meets the requirements. If everything is ready, it’s time to start. First, connect the pressure gauge, fluorine-filled hose, fluorine bottle or vacuum pump at the process port of the dehumidifier filter. After the container is evacuated with fluorine, the fluorine is slowly filled in. When the specified amount is charged, the valve of the fluorine bottle can be closed.
In the process of fluorine charging, pay attention to the current and voltage of dehumidification, and check it from time to time. Set the dehumidifier to run in the cooling or heating high-speed air state, and observe the change of the current while charging with fluorine. When the displayed current is close to the rated working current value, the valve of the fluorine bottle should be closed. However, the dehumidifier will continue to run for a while.
The pressure is also the same. By fine-tuning the amount of Freon and the gauge pressure, it can be accurately filled with fluorine. The main reason is that the low pressure is proportional to the indoor cooling load. In the fluorine filling process port and nearby pipelines, the ambient temperature has a great influence on its pressure and evaporation temperature, so the actual pressure is generally higher in summer. Lower in winter.
There are many ways to charge the dehumidifier with fluorine, and the quantitative fluorine filling method is generally used. When there is sufficient fluorine in the dehumidifier, the dehumidification effect will be better.
