3. When the temperature and humidity switch is switched to a refrigeration and dehumidification gear, if the humidity in the insulation displacement area is greater than the set humidity, the temperature and humidity controller outputs forward voltage to the refrigeration sheet, the temperature of one side close to the insulation rod is sharply reduced for the cold end while the temperature of the other side is sharply increased (the temperature of one side close to the insulation rod is transmitted to the other side), so that the temperature in the insulation displacement area is reduced, and when the airflow in the insulation displacement area passes through the radiator under the traction of the fan, the moisture in the airflow is condensed into liquid water on the radiator and is discharged through a water outlet below the radiator, thereby achieving the purpose of dehumidification.
4. When the temperature and humidity switch is switched to a heating and dehumidifying gear, if the humidity in the insulation displacement area is larger than the set humidity, the temperature and humidity controller outputs negative voltage to the refrigerating sheet, the temperature of one side close to the insulation displacement is sharply increased for the hot end temperature, and the temperature of the other side is sharply decreased (the temperature of the side close to the insulation displacement is transmitted to the other side), so that the temperature of the insulation displacement area is increased, and the moisture in the airflow is dried on the radiator when the airflow in the insulation displacement area passes through the radiator under the traction of the fan, thereby realizing the purpose of dehumidification.
5. When the temperature and humidity switch is switched to a constant-temperature gear, if the temperature in the order gram bar placing area is lower than a set temperature, the temperature and humidity controller outputs negative voltage to the refrigerating sheet, the temperature of one side close to the order gram bar is sharply reduced for the hot end while the temperature of the other side is sharply reduced (the temperature of the side close to the order gram bar is transmitted to the other side), so that the temperature of the order gram bar placing area is increased, and the temperature of the order gram bar placing area is increased when air flow in the order gram bar area passes through the radiator under the traction of the fan, so that the purpose of temperature increase is realized.
6. When the temperature and humidity switch is switched to a constant-temperature gear, if the temperature in the insulation displacement area is higher than a set temperature, the temperature and humidity controller outputs a forward voltage to the refrigerating sheet, the temperature of one side close to the insulation displacement is sharply reduced for the hot end while the temperature of the other side is sharply increased (the temperature of the side close to the insulation displacement is transmitted to the other side), so that the temperature in the insulation displacement area is reduced, the temperature in the insulation displacement area is reduced when the airflow in the insulation displacement area passes through the radiator under the traction of the fan, and the purpose of cooling is achieved.
Peltier effect (Peltier effect):
the peltier effect is discussed in a simple way-when current is passed through the thermocouple, one of the junctions dissipates heat and the other absorbs heat.
P-type semiconductor
A form of semiconductor material having a hole density in the conduction band that exceeds the electron density in the valence band. P-type material is formed by adding acceptor (acceptor) impurities.
N-type semiconductor
In one form of semiconductor material, a semiconductor having a greater density of electrons in the conduction band than holes in the valence band, the N-type material is obtained by incorporating donor impurities (doping), such as arsenic or phosphorus, into the crystal structure of silicon.
The semiconductor thermocouple is composed of an N-type semiconductor and a P-type semiconductor. The N-type material has redundant electrons and negative temperature difference potential. The P-type material has insufficient electrons and has positive temperature difference potential; when electrons travel from the P-type to the N-type through the junction, the temperature of the junction decreases, the energy thereof necessarily increases, and the increased energy corresponds to the energy consumed by the junction. Conversely, as electrons flow from the N-type to the P-type material, the temperature of the junction increases.
Direct contact thermocouple circuits are not available in practical applications and are therefore replaced by the connection method of the following figures, and experiments have shown that the introduction of a third material (copper connection pads and wires) into the thermoelectric circuit does not change the characteristics of the circuit.
Thus, the semiconductor element can be connected by various connection methods to meet the user's requirements. A P-type semiconductor element and an N-type semiconductor element are connected into a pair of thermocouples, and after a direct current power supply is connected, temperature difference and heat transfer are generated at the joints.
At the upper junction, the current direction is from N to P, the temperature drops and absorbs heat, this is the cold side; at the lower one, the current direction is from P to N, the temperature rises and heat is released, and is therefore hot.
Therefore, the semiconductor cooling sheet is formed by arranging a plurality of N-type and P-type semiconductor particles mutually, and the N/P are connected by a common conductor to form a complete circuit, usually copper, aluminum or other metal conductors, and finally two ceramic sheets are sandwiched like sandwich biscuit, and the ceramic sheets must be insulated and have good heat conduction, and the advantages are as follows:
1. the device does not need any refrigerant, can continuously work, has no pollution source and no rotating part, can not generate a rotation effect, has no sliding part, is a solid piece, has no vibration and noise during working, has long service life and is easy to install.
2. The semiconductor refrigerating sheet has two functions, namely refrigerating and heating, and the refrigerating efficiency is generally low, but the heating efficiency is very high and is always more than 1. Thus, one piece may be used instead of separate heating and cooling systems.
3. The semiconductor refrigerating plate is a current transduction type plate, high-precision temperature control can be realized through control of input current, and remote control, program control and computer control are easily realized through temperature detection and control means, so that an automatic control system is convenient to form.
4. The semiconductor refrigerating plate has very small thermal inertia, the refrigerating and heating time is very short, and the refrigerating plate can reach the maximum temperature difference when the power is on for less than one minute under the condition that the heat dissipation of the hot end is good and the cold end is idle.
5. The reverse use of the semiconductor refrigeration piece is just temperature difference power generation, and the semiconductor refrigeration piece is generally suitable for power generation in medium and low temperature regions.
6. The power of single refrigerating element pair of the semiconductor refrigerating sheet is very small, but the power is very large when the electric piles are combined, and the refrigerating system is formed by combining the electric piles of the same type in series and parallel connection, so that the refrigerating power can be in the range of several milliwatts to over ten thousand watts.
7. The temperature difference range of the semiconductor refrigerating sheet can be realized from a positive temperature of 90 ℃ to a negative temperature of 130 ℃.
The invention relates to a link rod constant-temperature and constant-humidity mobile memory which is mainly applied to the fields of electric power engineering, overhaul, construction and the like, is arranged on the roof of a car and is convenient to take and place, and the roof of a part of cars is provided with a solar cell for supplying power and can also be supplied with power by using a battery of the original car.
