Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The elevator air conditioner control method of the present invention will be described with reference to fig. 1 to 2. Referring to fig. 1, the present invention provides an elevator air conditioner control method, including the following steps:
s10, acquiring the inlet temperature of the evaporator and the outlet temperature of the evaporator;
s20, calculating a first temperature difference value of subtracting the outlet temperature from the inlet temperature;
s30, outputting the first temperature difference value, and adjusting the compressor power of the elevator air conditioner according to the first temperature difference value;
s40, obtaining the temperature in the elevator and the temperature of the elevator shaft;
s50, calculating a second temperature difference value obtained by subtracting the temperature of the elevator shaft from the temperature in the elevator;
s60, outputting the second temperature difference, and adjusting the lower air outlet power of the elevator air conditioner according to the second temperature difference;
s70, acquiring the number of people in the elevator;
and S80, adjusting the air supply power of the air conditioner of the elevator according to the number of people in the elevator.
In the conventional art, parameters of an elevator air conditioner are generally set by a worker, and the elevator air conditioner is continuously operated according to the preset parameters. However, various parameters of the elevator air conditioner are changed continuously in the running process, and if the elevator air conditioner runs continuously according to preset parameters, the improvement of the working efficiency of the air conditioner is not facilitated. For example, the temperature in the elevator, the number of people in the elevator and the ambient temperature all change during the continuous operation of the elevator air conditioner, so that the working state of the elevator air conditioner needs to be adaptively adjusted according to the parameters, and the improvement of the working efficiency of the elevator air conditioner and the use experience of users are facilitated.
Specifically, in the technical scheme provided by the invention, the inlet temperature and the outlet temperature of the evaporator are obtained, the evaporator is a heat exchanger of an indoor unit of the elevator air conditioner, the heat exchanger is used as the evaporator in a refrigerating state and is used as the condenser in a heating state, the heat exchanger is called as the evaporator in a unified way in the invention, and the name distinction is not carried out when refrigeration or heating is carried out.
Because the evaporator is the main heat transfer device of air conditioner, its operation effect can directly influence the heat transfer effect in the elevator. The evaporator generally has a plurality of flow paths, and the coil is generally arranged on a certain branch flow and is easily affected by uneven flow distribution to cause detection deviation, so that the temperature of the inlet and the outlet of the evaporator is respectively obtained by the invention, the detection deviation can be well reduced, and the temperature sensors can be arranged at the inlet and the outlet of the evaporator for temperature detection, which is not limited by the invention.
As mentioned above, the evaporator is the main heat exchange device, so the difference between the inlet and outlet temperatures of the evaporator can reflect the heat exchange capability of the air conditioner. It should be noted that, in the cooling state, the inlet temperature of the evaporator is less than the outlet temperature, and at this time, the first temperature difference is a negative value, and in the heating state, the inlet temperature of the evaporator is higher than the outlet temperature, and at this time, the first temperature difference is a positive value.
Further, the new trend air conditioner in the existing market has increased the lower air outlet with external intercommunication, has also used lower air outlet in a lot of elevators, can circulate with the outer air of elevator through this lower air outlet and exchange, improves the user and uses experience. Under the general condition, when the elevator is in the operation in-process, lower air outlet mainly used elevator and elevator shaft's air exchange, when the difference in temperature appears in elevator and elevator shaft, can utilize down the air outlet to carry out the supplementary work efficiency that improves the air conditioner of heat transfer. According to the technical scheme provided by the invention, the temperature in the elevator and the temperature of the elevator shaft are obtained, the difference value between the temperature in the elevator and the temperature of the elevator shaft is calculated to obtain the second temperature difference value, and the temperature difference between the interior of the elevator and the elevator shaft can be calculated through the second temperature difference value to assist the air conditioner in heat exchange.
As described above, the usage of the elevator is constantly changing, and the highest factor in the change is the change in the number of people in the elevator, in addition to the temperature. For example, elevators in office buildings have a large number of people moving in the morning and evening at peak hours, and the number of people may be small at ordinary times. In the technical scheme provided by the invention, by identifying the number of people in the elevator and correspondingly selecting proper operation parameters, when the number of people in the elevator is large, the air conditioner is operated at higher power to contribute to rapid cooling, and when the number of people in the elevator is small, the air conditioner is operated at lower power to contribute to energy conservation and emission reduction.
Specifically, the step S30 of adjusting the compressor power of the elevator air conditioner according to the first temperature difference includes:
s31, if the absolute value of the first temperature difference is larger than a first preset value, improving the power of a compressor of the elevator air conditioner;
s32, if the absolute value of the first temperature difference is smaller than a second preset value, reducing the compressor power of the elevator air conditioner;
s33, if the absolute value of the first temperature difference is larger than the second preset value and smaller than the first preset value, keeping the power of a compressor of the elevator air conditioner unchanged;
wherein the first preset value is greater than the second preset value.
The inlet and outlet temperatures of the evaporator reflect the heat exchange efficiency of the evaporator, and if the inlet and outlet temperature difference of the evaporator is large, the heat exchange effect is poor, and the power of the compressor needs to be improved. Generally, the first preset value is set to 3, and if the temperature difference between the inlet and the outlet of the evaporator exceeds 3, the power of the compressor needs to be increased to improve the heat exchange effect. Approximately, the second preset value is set to be 2, and if the absolute value of the first temperature difference value is smaller than 2, the fact that the temperature difference between the interior of the elevator and the elevator shaft is lower at the moment is proved, the heat exchange requirement is not large, the power of the compressor is higher, and the power of the compressor needs to be reduced to achieve the effect of saving energy. Of course, when the first temperature difference value is between the first preset value and the second preset value, it indicates that the heat exchange effect of the current evaporator is good, and the current compressor power can be kept running.
Specifically, S60, "adjusting the lower outlet air power of the elevator air conditioner according to the second temperature difference" includes:
s61, judging the operation mode of the air conditioner;
s62, under the heating mode, if the second temperature difference is smaller than 0, the lower air outlet power of the elevator air conditioner is improved;
s63, if the second temperature difference is larger than 0, reducing the lower air outlet power of the elevator air conditioner;
s64, in the refrigeration mode, if the second temperature difference is smaller than 0, reducing the lower air outlet power of the elevator air conditioner;
and S65, if the second temperature difference is larger than 0, improving the lower air outlet power of the elevator air conditioner.
Through the adjustment of air outlet power down, can improve the inside and outside heat transfer effect of elevator. In winter, the air conditioner heats, if the temperature is less than the elevator shaft temperature in the elevator, the second temperature difference value is less than 0 this moment, can improve down air-out power, exchange the air of elevartor shaft to the elevator in, the supplementary heat exchange that carries on, if the second temperature difference value is greater than 0, air-out power need reduce this moment, prevents the heat loss. Further, in summer, the air conditioner refrigerates, and when the number of people is more in the elevator, the condition that the temperature is higher than the temperature of the elevator shaft in the elevator can appear, and the second temperature difference value is greater than 0 at the moment, so that the lower air outlet power of the air conditioner needs to be increased, and the cooler air in the elevator shaft is replaced into the elevator. Similarly, if the temperature of the elevator shaft is higher than the temperature in the elevator, the lower air outlet power is reduced, and hot air is prevented from entering the elevator to increase the temperature in the elevator. Through the technical scheme provided by the invention, the heat exchange of air can be assisted according to the temperature difference between the inside and the outside of the elevator, and the heat exchange effect of the elevator air conditioner is improved on the basis of energy conservation.
Specifically, S80, where "adjusting the air supply power of the air conditioner of the elevator according to the number of people in the elevator" includes:
s81, in a refrigeration state, if the number of people in the elevator exceeds a first number of people, improving the air supply power of an elevator air conditioner;
s82, if the number of people in the elevator is smaller than a second number of people, reducing the air supply power of the elevator air conditioner;
wherein the first person value is greater than the second person value.
As mentioned above, when the elevator air conditioner is in a refrigeration state, heat dissipation is difficult when the number of people in the elevator is large, and the air conditioner needs to adopt high air supply power, which is beneficial to improving heat dissipation efficiency; when the number of people in the elevator is low, the air supply power can be properly reduced, and the energy is saved. In the technical scheme provided by the invention, the first person numerical value and the second person numerical value can be set according to the carrying capacity of the elevator, for example, for an elevator with carrying capacity of 15 persons, the first person numerical value can be set to be 10, the elevator is crowded at the moment, the air supply power of an elevator air conditioner needs to be improved, the second person numerical value is 5 persons, the persons are scattered at the moment, and the air supply power is reduced, so that a good cooling effect can be ensured; for a small elevator with a carrying capacity of 10 people, the first people number can be set to 7, and the second people number can be set to 3, which is not limited by the invention. It should be noted that, in the case of elevator heating, the situation may be the opposite of the case of cooling, and when the number of people is large, the elevator air conditioner operates at a low power, and when the number of people is small, the elevator air conditioner operates at a high power.
Further, at S82, the method includes, after reducing the air supply power of the air conditioner of the elevator if the number of people in the elevator is smaller than a second number of people:
s83, if the number of people in the elevator is larger than the second number of people and smaller than the first number of people, obtaining the heat dissipation temperature in the elevator, and adjusting the air supply power of the air conditioner of the elevator according to the heat dissipation temperature in the elevator.
Specifically, S83, where "adjusting the air supply power of the air conditioner of the elevator according to the heat dissipation temperature in the elevator" includes:
s831, if the heat dissipation temperature in the elevator is higher than a temperature threshold value, improving the air supply power of the elevator air conditioner;
and S832, if the heat dissipation temperature in the elevator is at the temperature threshold, keeping the air supply power of the air conditioner of the elevator unchanged.
It should be noted that, when the number of people in the elevator is greater than the second number of people and less than the first number of people, the air supply power of the elevator air conditioner needs to be controlled by the heat dissipation temperature in the elevator, the heat dissipation temperature in the elevator can be obtained by acquiring the area temperature between users in the elevator, and can be detected by an infrared temperature measuring device, and the invention is not limited. When the elevator is in a refrigerating state, the temperature threshold value can be set to be 28-30 ℃, if the heat dissipation temperature in the elevator is larger than the temperature threshold value, even if the number of people in the elevator does not meet the condition of being larger than the first person numerical value, the air supply power of the elevator air conditioner needs to be improved, because the physique and the body state of a user are different, the situation of sultriness also exists in the elevator even if the number of people in the elevator is small, the detection of the heat dissipation temperature in the elevator needs to be assisted, and the use experience of the user is improved. In addition, if the heat dissipation temperature in the elevator is within the temperature threshold, the air supply power of the elevator air conditioner is kept unchanged. Specifically, "increasing the air supply power of the elevator air conditioner" includes: the rotating speed of the fan is improved, and the opening and closing angle of the air outlet and the air inlet is increased.
