be equipped with first temperature sensor 47 on the cold source board 3, be equipped with second temperature sensor 48 on the heat source board 4, be equipped with third temperature sensor in the car 1, third temperature sensor is used for detecting the inside temperature of car, and third temperature sensor can fix the inboard at car panel 6 or roof 32, and the outside of car 1 is equipped with fourth temperature sensor, and fourth temperature sensor is used for detecting ambient temperature.
The working principle is as follows: the semiconductor refrigeration sheet 7, the fan 10, the three-way reversing valve 11, the motor 46, the first temperature sensor 47, the second temperature sensor 48, the third temperature sensor and the fourth temperature sensor are all connected to a control system of the elevator.
When the environment temperature detected by the fourth temperature sensor (the environment temperature is preferably the average temperature within 24 hours continuously to reduce the influence caused by temperature difference fluctuation between day and night and reduce the energy consumption waste caused by the false start of the air conditioning system) is between 10 and 25 ℃, the environment temperature is proper, the temperature in the elevator car is unnecessary to be adjusted in spring and autumn for most areas, and the control system of the elevator enables the semiconductor refrigeration sheet 7 not to be electrified and not to work.
When the ambient temperature detected by the fourth temperature sensor is lower than 10, which indicates that winter has entered, the air conditioning system needs to have the capability of warming at any time. The control system controls the state of the three-way reversing valve 11, so that the air outlet of the fan 10 is communicated with the second air inlet 9. The control system enables the semiconductor refrigerating sheet 7 to be electrified to work, the cold source plate 3 becomes cold, the heat source plate 4 becomes hot and stores heat, and the maximum temperature difference between the cold source plate 3 and the heat source plate 4 can reach more than 60 ℃. Because the first air hole 28 and the third air hole 30 are not covered, the air passes through the first air channel 14 to take away the cold air on the cold source plate 3, on the basis of keeping the maximum temperature difference between the cold source plate 3 and the heat source plate 4 unchanged, the temperature of the heat source plate 4 can be further increased, more heat is stored, and the heat source plate 4 is in a sealed space, so that the heat loss is less, and the energy consumption is saved. When a person calls a call and the elevator is to be used, before the control system sends a door opening signal to the car door, the control system starts the fan 10 firstly, airflow enters the inside of the car through the three-way reversing valve 11, the second air inlet 9, the second air duct 16, the third air duct 13 and the air outlet 12, and the airflow absorbs heat on the heat source plate 4 when passing through the second air duct 16, so that the temperature in the car 1 rises. When the passenger arrives at the corresponding floor and the control system sends a door closing signal of the car door, the control system enables the fan 10 to be closed, and the semiconductor refrigerating sheet 7 continues to work to recover the heat in the heat source plate 4. When the second temperature sensor 48 detects that the temperature of the heat source plate 4 is at a high level, the control system stops the semiconductor refrigeration sheet 7, and when the temperature of the heat source plate 4 is reduced to a certain degree, the control system enables the semiconductor refrigeration sheet 7 to work again and again, so that the heat source plate 4 always has a high temperature and is ready to be heated at any time. When the air flow flows in the second air duct 16, the air flow flows downwards and then horizontally, then flows upwards through the spaces between the second vertical plates 25, pushes the second rotating plates 26 to rotate upwards, then enters the third air duct 13, flows downwards, and enters the car 1 from the air outlets 12.
When the ambient temperature detected by the fourth temperature sensor is higher than 25 ℃, the fact that summer season is entered means that the air conditioning system needs to have the capacity of refrigerating at any time. The control system controls the state of the three-way reversing valve 11, so that the air outlet of the fan 10 is communicated with the first air inlet 8. The control system enables the semiconductor refrigerating sheet 7 to be electrified to work, the cold source plate 3 becomes cold and stores cold, and the heat source plate 4 becomes hot. The control system makes the motor 46 drive the rotating rod 43 to rotate a certain angle, one end of the rotating rod 43 drives the second baffle 3 to rotate a certain angle downwards through the first rope 44, the second baffle 36 covers the first air hole 28, the first baffle 34 is driven by the second baffle 3 to tilt upwards, so that the second air hole 29 is exposed, the other end of the rotating rod 43 drives the fourth baffle 40 to rotate upwards through the second rope 45, the fourth baffle 40 covers the third air hole 30, the third baffle 39 is driven by the fourth baffle 40 to tilt downwards, so that the fourth air hole 31 is exposed, the fourth air hole 31 and the second air hole 29 are simultaneously exposed, so that the heat of the heat source plate 4 is dissipated in an accelerated manner, the air passes through the second air duct 16 to take away the heat on the heat source plate 4, on the basis of keeping the maximum temperature difference between the heat source plate 3 and the heat source plate 4 unchanged, the temperature of the heat source plate 3 can be further reduced, more cold air can be stored, and the heat source plate 3 is in a relatively sealed environment, the cold loss is less, and the energy consumption is saved. When a person calls a call and the elevator is to be used, before the control system sends a door opening signal to the car door, the control system starts the fan 10 firstly, the air flow enters the inside of the car through the three-way reversing valve 11, the first air hole 28, the first air channel 14, the third air channel 13 and the air outlet 12, the temperature of the air flow is reduced by the cold source plate 3 when the air flow passes through the first air channel 14, so that the temperature in the car 1 is reduced, and the hot air in the car can be rapidly expelled after the car door is opened due to the fact that the air outlet 12 is over against the car door, so that the temperature of the car is rapidly reduced. When the passenger arrives at the corresponding floor and the control system sends a door closing signal of the car door, the control system enables the fan 10 to be closed, and the semiconductor refrigeration sheet 7 continues to work to recover the low temperature of the cold source plate 3. When the first temperature sensor 47 detects that the temperature of the cold source plate 3 is at a low level, the control system stops the semiconductor refrigeration sheet 7, and when the temperature of the cold source plate 3 rises to a certain degree, the control system enables the semiconductor refrigeration sheet 7 to work again and again, so that the cold source plate 3 has a lower temperature all the time and is ready to refrigerate at any time. When flowing in the first air duct 14, the airflow first flows downward, then flows horizontally, then flows upward through the spaces between the second vertical plates 25, then flows horizontally, pushes away the first rotating plate 22, enters the third air duct 13, flows downward, and enters the interior of the car 1 from the air outlets 12.
In order to further improve the cold storage capacity of the cold source plate 3, on the basis of adopting the thicker cold source plate 3, the inside of the cold source plate 3 is hollowed, and water with larger specific heat capacity is poured, wherein the water can also be refrigerating fluid and plays a role in anti-icing. Similarly, in order to further increase the heat storage capacity of the heat source plate 4, the heat source plate 4 is filled with water.
