Common louver openings include a single-layer louver opening, a double-layer louver opening, a side-wall grille opening, a slit-type grille opening and the like, and the specific manner of the louver air return opening 13 is within the scope of the present embodiment. Besides, the concentrated air volume of the outlet air of the jet air outlet 15 is larger, and the dispersed air volume of the outlet air different from the dispersed air volume of the dispersed air inlet is smaller, the jet air outlet 15 can be set by adopting a spherical air inlet, the spherical air inlet has the function of remote jet flow, and similarly, the strip-shaped air inlet or the jet air outlet 15 with other shape setting modes also belong to the description range of the embodiment.
In another specific embodiment, the number of the refrigeration units is specifically two, the two refrigeration units are specifically a first refrigeration unit 1 and a second refrigeration unit 2, and the first refrigeration unit 1 and the second refrigeration unit 2 are arranged side by side, are independent of each other, and do not interfere with each other.
The temperature difference of the inlet air and the outlet air of the semiconductor refrigeration elevator car air conditioning system mainly depends on the temperature of the inlet air, the air inlet volume, namely the air speed of the cross flow fan 9, the opening degree of the middle air supply volume, namely the adjustable air supply opening 14, the starting number of the refrigeration components and the running condition. When no person is in the car box body 20, a single refrigerating unit is adopted to operate, namely the first refrigerating unit 1 or the second refrigerating unit 2 operates in a single mode, when a person is carried in the car box body 20, the refrigerating units which do not operate are started, namely the first refrigerating unit 1 and the second refrigerating unit 2 operate in double modes, and under the condition that jet flow air outlet is adopted for air outlet, the requirement for refrigeration can be rapidly met in an air outlet area. Because the number of people in the car box body 20 of the elevator and the switching frequency of the elevator door have great randomness, the temperature in the car box body 20 is easy to fluctuate or rise, and an area with lower temperature can be quickly arranged in an air supply and air outlet area based on the condition and the characteristic that the semiconductor has quick refrigeration combined with a jet flow air outlet mode. Can at least ensure a certain comfortable feeling to the human body. The embodiment only gives the number of the refrigeration units as two, and other technical solutions obtained by simply changing the number also belong to the description scope of the embodiment.
In the present embodiment, the circulating air duct is divided into a circulating outer air duct 10 from the air return opening to the air outlet opening to convert the hot air into the cold air, and a circulating inner air duct 11 from the air outlet opening to the interior of the car body 20. The adjustable opening and closing of the adjustable air plate 18 forms an adjustable air supply opening 14 with adjustable opening and closing. The suction opening of the cross-flow fan 9 faces the air return opening 13 of the shutter, the cross-flow fan 9 is in butt joint with the circulating outer air duct 10, the first semiconductor component 3, the adjustable air supplement opening 14 and the second semiconductor component 4 are sequentially installed at the top of the circulating outer air duct 10, cold end radiators 8 of the first semiconductor component 3 and the second semiconductor component 4 are installed in the circulating outer air duct 10, the circulating outer air duct 10 is next to the circulating inner air duct 11, and finally a jet air outlet 15 is installed.
In this embodiment, first semiconductor component 3 and second semiconductor component 4 regard as the semiconductor refrigeration subassembly, and first semiconductor component 3 and second semiconductor component 4 series refrigeration can make the air flow through the semiconductor refrigeration subassembly after, can realize great degree of cooling. Due to the semiconductor refrigeration characteristic, the refrigerating unit has large cooling capacity in a closed circulation air supply mode, but the performance of the whole refrigerating unit is slightly low, but after the adjustable air supply opening 14 is opened, the performance of the whole refrigerating unit can be improved. If adjustable air supply opening 14 is not opened, the temperature of the air flowing through second semiconductor component 4 is lower, and the temperature difference between the cold end and the hot end of the semiconductor refrigeration component is increased, so that the performance of the semiconductor is reduced, if the temperature of the inlet air of second semiconductor component 4 is increased by opening adjustable air supply opening 14, the temperature of the mixed air flow is uniformly distributed under the flow guiding effect of guide plate 16, the overall performance of the semiconductor refrigeration component is improved, and more energy is saved. The refrigerating capacity is increased due to the increase of air quantity and the improvement of performance.
The air supply temperature, the air supply quantity and the refrigerating quantity are regulated and controlled through the adjustable air supply port 14 so as to meet the requirements of heat load change and air supply temperature inside the elevator car box body 20; by setting the running number of the refrigerating units, the change of the heat load in the cage body 20 can be coped with, and the air supply temperature is kept unchanged; the variation of the load in the car body 20 can also be dealt with by the operating power of the semiconductor refrigeration assembly and the rotating speed of the cross flow fan 9, and it is within the scope of the present embodiment when the semiconductor refrigeration assembly is not operated and the cross flow fan 9 is operated to provide the circulation of air.
In addition, the switching between the closed type circulating air supply and the air supply mode with fresh air is realized through the adjustable air supply opening 14, namely the opening and the closing of the adjustable air supply opening 14, and in order to realize quick refrigeration and meet the ventilation inside the elevator car box body 20, when the heat load in the elevator car is low, the refrigeration is realized by adopting the ventilation mode with fresh air, so that the ventilation and refrigeration requirements can be met; however, when the heat load in the car box 20 is high, a semiconductor refrigeration mode with fresh air can be adopted firstly until the ventilation requirement is met and the air temperature in the car box 20 is slightly reduced, and then the adjustable air supply opening 14 is closed and the closed type circulating air supply mode is opened, so that the temperature of the car can be quickly reduced.
