Home air-conditioning systems (systems) sometimes prevent ice. The ice block appears to be a piece of ice blocking the air circulation in front. The air-conditioning is useless to open, and the house is still warm. The appearance of air-conditioning ice blocking, so that some can refer to: Shanghai Central Air-conditioning Project

1. The filter drier (function: filtering impurities, etc.) is aging and loses its function of drying and water absorption. Air conditioning repair

2. The water is not removed immediately, causing excessive cooling of the water, and charging will result in ice cubes.

3. This process (guò chéng) is not sealed. They will not quickly repair the central air-conditioning installation. The terminal equipment of the central air-conditioning is a fan coil unit. Whether it is exposed or concealed, first determine the position and output of the fan coil. The location of the air outlet and the location of the return air outlet, when determining the location and direction of the pipeline, the nearest, the fewer detours, the better, and the connection to the main pipeline is complete. Install hoses, valves, solenoid valves at the inlet and outlet of the fan coil, and see the drawing requirements for the filter. If the air outlet is far away from the machine, add a wind pipe (the outlet pipe needs to be insulated) and a soft canvas connection. In the long-delayed frost or the small boat that opens irregularly, the moisture in the air enters the machine through the nozzle. The compressor is not hermetically sealed, placed for a long time, and the change of using frost to dry it may also cause ice scale.

4. Evaporation loss (loss), long time in the storage room of frozen (hidden) water molecules, together with the water vapor molecules in the air compressor (the inner vacuum power supply, the atmospheric pressure is the water molecular machine in the moist air). Shanghai air conditioning design

5, the water vapor in the air is compressed and injected into the ice caused by the pipeline leakage inspection pressure.

6, the compressor is not sealed and placed for a long time, and the change of frost when it is not fully dried can also cause ice blockage and dirty blockage.
