The application discloses a semiconductor constant temperature box and a constant temperature control method. The method includes: obtaining the current temperature in the cabinet; determining the absolute value of the difference between the current temperature and the set constant temperature target temperature; if the current temperature is greater than the constant temperature target temperature, and the absolute value of the difference is less than the set refrigeration mode selection threshold, Then use the first cooling mode to work, and reduce the absolute value of the difference by controlling the cooling of the semiconductor refrigeration sheet. During the process of reducing the absolute value of the difference, the cooling power of the semiconductor refrigeration sheet is controlled to decrease; if the current temperature is lower than the constant temperature target temperature , and the absolute value of the difference is less than the set heating mode selection threshold, the first heating mode will be used to work, and the absolute value of the difference will be reduced by controlling the heating of the semiconductor refrigeration sheet. During the process of reducing the absolute value of the difference , to control the heating power of the peltier cooler to decrease. The application can approach from a relatively high or low temperature until reaching the constant temperature target temperature, realizing precise temperature control of the semiconductor thermostat.
Description
technical field [0001] The present application relates to the technical field of semiconductor refrigerators, in particular to a constant temperature control method for a semiconductor thermostat and a semiconductor thermostat. Background technique [0002] Semiconductor refrigerators, also known as electronic refrigerators. It is a product that is completely different from ordinary refrigerators in terms of refrigeration principles. It uses a semiconductor refrigeration chip to achieve refrigeration through high-efficiency annular double-layer heat pipe heat dissipation and conduction technology. [0003] In the prior art, after the semiconductor refrigerator is started, it will automatically control the semiconductor refrigeration sheet to work and refrigerate with high power, so that the temperature will drop to a normal working temperature preset by the manufacturer, so that users can use it. [0004] However, in practical applications, the above-mentioned working mode ...
