The working principle of the home chest freezer is to radiate heat from the room and then transfer it to the outdoors. Therefore, the higher the external temperature, the more difficult it is for the motor to work.
Positioning is a major issue. Do not place refrigerators or freezers near boilers or cooking utensils. Make sure that the rear of the refrigerator or freezer is well ventilated so that air can easily flow through the back. Just like a car radiator, airflow is needed to effectively remove heat.
People often put the solar chest freezer in the garage or even the garden shed. Winter is good in winter, but due to low insulation, these rooms become very hot in summer, so the freezer must use more electricity to work harder. However, if the room temperature is too low, many solar chest freezers will not work properly.
As with most appliances, stores (including online stores) will display the energy level of the freezer. At least an A grade is required, preferably A+. Your freezer runs 24 hours a day without interruption, and electricity costs are high.
In addition, a machine with higher rated power will have more insulation and a longer holding time when the power is cut off. Some retailers will tell you how long the refrigerator will last. This may vary between 5 hours and 18 days!
Discussions about power shortages and blackouts continue until the new power plant is put into operation. It is a good idea to buy refrigerators that can maintain the temperature. The chiller can be operated by time control in order to utilize solar power generation equipment.
With a freezer, regular defrosting is beneficial. If the frost builds up too quickly, check the door seal. You can fold the newspaper and close the door. If the paper falls, there is a problem with the door seal and it must be replaced.
Some freezers have an automatic defrost function, which obviously saves time, but the cost of automatic defrost will be 40% more. Although the thermostat must be in overdrive to make it freeze again during manual defrosting, this is still by far the cheapest option. The cost of manual defrosting is also lower!
