Craft beer equipment requires extensive cooling in the brewing chamber and during fermentation to meet the needs of the process. The process in the brewing chamber is to cool the wort to the temperature required for yeast propagation. The focus of the fermentation process is to maintain a constant temperature in the tank, using glycol water or alcoholic aqueous solutions to take away the temperature generated by the yeast breaking down the wort and to stabilise the internal environment in which the yeast live.
 
As the cooling of the air-cooled cooler is done by circulation with the outside air, the temperature and humidity of the outside air as well as the floating matter in the air have an effect on the cooling effect.
 
For all three of the next, care should be taken when installing and using:
 
1. Temperature: This should be borne in mind when choosing the location of the installation. Try to install the unit in a cool, ventilated area at the back of the house. As it is pulled upwards, a ventilation distance of 40 cm should be left around the unit, so that a large temperature difference and smooth ventilation can improve the energy efficiency ratio of the unit.
2. Humidity: High humidity air cools more efficiently than dry air.
3. Floating matter: Poplar catkins, hair, dust, etc. are attracted to the surface of the condenser by the fan and thicken. This reduces the effectiveness of air circulation and increases the load on the compressor. Energy consumption increases, cooling becomes less effective and when the current increases the compressor can even be burnt out. It is therefore necessary to clean any adhering material from the surface of the condenser in good time.
 
In addition, as with domestic air conditioners, some Freon must be added every year. During the use of the chiller, we should also be aware of changes in the cooling effect, which is reflected in the high and low pressure gauges of the unit. When the unit is running, the pointer value of the high pressure gauge will reflect the current pressure and temperature. This temperature should be 5-10°C higher than the ambient temperature. If the temperature difference is found to be below this range, this indicates that the current cooling effect is not good and there may be a Freon deficiency problem.
 
After understanding the working principle and precautions of air-cooled chillers, you will also understand the daily maintenance work. More attention should be paid to eliminating small problems so that they do not accumulate and cause major breakdowns.
