Mechanical thermostat mainly refers to a temperature control method that adjusts refrigeration by rotating the button, with an expanding thermostat, which will automatically expand and contract according to the change of temperature, so as to control the power supply, the most primitive type, and the structure is relatively simple.
Advantages of mechanical thermostats:
(1) The structure is simple, the price is cheap, the cost is low, and the price of the mechanical temperature control freezer is affordable.
(2) Due to the simple structure, the thermostat is strong and durable, with high stability, not easy to fail, and at the same time, it is relatively simple and convenient to maintain, and the cost is low.
(3) No electricity is required during operation.
Disadvantages of mechanical thermostats:
(1) The accuracy of temperature control is inferior to that of the computer temperature control system, due to the inaccurate temperature control, the temperature in the freezer is unstable, and the temperature cannot be controlled independently by refrigeration and freezing.
(2) The mechanical temperature control freezer cannot realize the real independent refrigeration system, the preservation effect is not good enough, and there is the problem of food flavor.
(3) The convenience of operation is poor, and the freezer needs to be opened to complete the operation.
Electronic thermostat mainly refers to a temperature control mode that adjusts refrigeration through microcomputer control and electronic display display, and controls the power supply according to the temperature sensing function and thermal resistance timing, which is a more advanced temperature control mode with a complex structure.
Advantages of computerized thermostats:
(1) The temperature can be controlled independently, and the specific temperature can be set, and the temperature control is more accurate, which can make the temperature of the freezer very stable.
(2) The computerized temperature-controlled freezer can realize an independent refrigeration system, so that the refrigeration effect of the freezer is better, the preservation effect is also better, and the problem of food cross-smell is eliminated.
(3) The LCD display is clear and clear, the display is very intuitive, and the operation is relatively simple.
(4) Powerful, fully automatic control, one table and multiple control.
Disadvantages of computerized thermostats:
(1) The price is relatively expensive and the cost is high, resulting in a high price of the freezer.
(2) Due to the complex structure, it is difficult to maintain faults and the cost is high.
(3) Independent power supply is required.
