Shenhai Explosionssäker
Under vintern, vissa användare möter utmaningar som långsam uppvärmning eller ineffektiv värme från sina explosionssäkra luftkonditioneringsapparater. Nedan följer en analys av de troliga orsakerna till dessa problem, som syftar till att ge vägledning:
1. Delvis, inefficient heating is due to an overaccumulation of dust in the air filters and blockages in the vents of both indoor and outdoor units. The role of the filter is to capture airborne dust. An excessive accumulation, if not cleaned promptly, impedes airflow, causing a decrease in air discharge and leading to inadequate heating. This isn’t a malfunction but a maintenance issue, which can be resolved by routinely cleaning the air filters.
2. When heating, a lower ambient temperatur can diminish the explosion-proof air conditioner’s efficiency, leading to suboptimal heating, a normal occurrence. Därav, experts recommend opting for electrically heated models for superior performance.
3. Fluoride shortage is another issue. Many now utilize heat pumps or auxiliary electric heating. Both methods absorb heat from outdoor air when the refrigerant evaporates. With lower outdoor temperatures, the reduced temperature differential with the refrigerant’s evaporation temperature affects the heat exchange, diminishing the warm airflow. Så, older models with significant compressor wear might not perform satisfactorily when the outdoor temperature dips below 0℃. Också, if the nuts at the copper pipe bell mouth are loose post-installation or the machine has been moved, a refrigerant shortage should be considered.
4. Circuit control malfunctions are also frequent, such as when the outdoor unit malfunctions, often due to capacitor, temperature sensor, or mainboard issues.
5. Faults sometimes occur in the four-way solenoid valve or its control circuit, and there might be issues with AC contactors, thermostats, and thermal fuses. These all necessitate an onsite diagnostic by a professional technician.
