What causes the air bombing And prevent it?

The water from the condenser (Condenser) in which water becomes ice on the surface of the evaporator. At lower temperature, the faster clotting. So if the temperature is over. 0 degrees Celsius would be no ice on air-hardening evaporation of water will make the poor thermal conductivity. shaved ice Therefore, the rate of heat transfer from the cooling area is reduced. This means that the refrigerant temperature shaved ice is lower than it should be, and the coagulation of the water makes it difficult to exchange heat. The heat capacity of the evaporator is lower.
The fins of the evaporator, if the erection of water occurs, it will decrease the space between the fins and the fin contact area between air and dropped. Thermal conductivity will decrease. And to reduce the temperature and causes more clotting. When water is solidification shaved ice and volume increases will cause fin damage. Water is solidification shaved ice island on the evaporator will be reduced. The defrosting process is called shaved ice There are several methods together.
2. Water defrosting is spraying water onto the ice island. The valve is closed, the flow of liquid. After turning off the compressor. This will cause the fan to stop working in the evaporator, spray water over the evaporator will be running a few minutes until the ice melts and the water will flow out.
3. Electrical defrosting the heat from the heater to defrost. By closing the flow of refrigerant. Air compressor is off Heater turns The fan is off And will be heated to melt the ice after heating is off. Air compressor starts Valve opening The refrigerant then flows back. And it turns the fan Processes are automated.
4. H ot gas defrosting by hot gas defrost. How is the ice on the evaporator system to order the closure of the valve, the refrigerant before entering the evaporator. Then open the bypass valve refrigerant out of the compressor without content. Model of the state as steam and high temperature to the evaporator. Ice around the evaporator, it will melt. And was ordered to return to the same devices.
These methods are used, whether it is the right way. Warm water onto the ice island. The heat from the heater to defrost. Hot gas defrost Ice will melt when turned on, switches the device. The heat from the air compressor. Cooling system must be defrosting when low temperatures occur frequently. Some way by the shutdown until the ice melts in your case. Refrigerator For refreshments in stores.
