Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and examples.
The embodiment provides a train room air conditioner, which comprises a cabinet body, a plurality of longitudinally arranged fan assemblies and an evaporator assembly 1, wherein the fan assemblies and the evaporator assembly are mounted in the cabinet body, the cabinet body comprises a front door panel (not shown) and a rear door panel (not shown) which are in relative position relation, and a left side panel (not shown) and a right side panel (not shown) which are in relative position relation, and an air return opening (not shown) and an air outlet (not shown) are respectively formed on the rear door panel and the front door panel of the cabinet body.
A plurality of fan subassemblies are vertically installed in the air outlet side to in time discharge the air after the heat transfer. In the present embodiment, each fan assembly includes a fan (not shown), a fan for driving the fan to rotate, and a fixing plate (not shown) for fixing the fan and the fan, and the number of the fan and the fan in each fan assembly is two and is arranged longitudinally. Therefore, in the embodiment, the air outlet side of the inter-row air conditioner is provided with 4 fans F1-F4 which are longitudinally arranged.
Of course, the number of the arranged fans is not limited to the number described above.
The area corresponding to the air return inlet is marked as the air return area, and the area corresponding to the air outlet is marked as the air outlet area. In this embodiment, the air outlet area is divided into an upper area, a middle area and a lower area, which are respectively marked as an air outlet area a, an air outlet area B and an air return area C; correspondingly, the air return area is also correspondingly divided into an upper area, a middle area and a lower area which are respectively marked as an air return area D, an air return area E and an air return area F.
In this embodiment, in order to guarantee cold volume output, satisfy the evenly distributed of a plurality of fan directions, the inside evaporimeter subassembly 1 of air conditioner corresponds with the fan subassembly between the row, guarantees that fan from the top down return air side can both correspond with evaporimeter subassembly 1 in each fan subassembly. The adjustment of different evaporation capacities on the evaporator assembly 1 is realized by adjusting the air outlet rotating speed of each fan, so that the refrigerating capacity requirements of different air outlet areas A-C are met.
The refrigerating capacity requirement of each air outlet area a-C can be determined according to actual conditions, and in this embodiment, the following three conditions can be included: (1) the required refrigerating capacity in each of the air outlet areas A-C is the same, and the air outlet areas A-C are applied to the condition of load balance of the upper layer, the middle layer and the lower layer; (2) different air outlet areas A-C have different required refrigerating capacities according to the load conditions, and are applied to the condition that the loads of the upper layer, the middle layer and the lower layer are unbalanced; (3) the air outlet temperature in each air outlet area A-C is the same, and the condition that the air outlet temperature in different air outlet areas is the same is met.
According to the basic formula of the refrigerating capacity: q = W C Δ T, where W represents the weight of the material, where the amount of air is indicated; c represents specific heat and is a constant value; Δ T represents the temperature difference between the return air temperature and the outlet air temperature.
According to the formula, the refrigerating capacity is respectively related to the air outlet volume, the return air temperature and the temperature difference between the air outlet temperatures, wherein the air outlet volume of each fan is positively related to the third power of the rotating speed of each fan, the actual air outlet temperature is weakly negatively related to the air outlet volume, the larger the air outlet volume is, the higher the actual air outlet temperature is, and the influence of the part on the refrigerating capacity is negative.
According to experimental tests, the correlation between the air outlet volume and the return air temperature and the air outlet temperature is obtained, wherein the return air temperature is kept at a certain value. When the air outlet volume is small, the influence on the air outlet temperature is small; the air outlet temperature is increased along with the increase of the air outlet quantity; when the air-out amount of wind increases to a definite value, the air-out temperature tends to be unchangeable, because, the air-out amount of wind is too big and can't acquire more cold volumes from evaporimeter subassembly 1, and the air-out amount of wind is too big, can cause the air-out temperature to be close to the return air temperature.
Therefore, the required distribution of the cooling capacity is realized by adjusting the air outlet rotating speed of each fan corresponding to each air outlet area A-C according to the comprehensive consideration of the air outlet quantity, the temperature difference between the return air temperature and the air outlet temperature and the required refrigerating capacity of each air outlet area A-C.
[ obtaining Return air temperature and Outlet air temperature ]

In this embodiment, the temperature of each air outlet region a-C is acquired by arranging a corresponding air outlet temperature sensor in each air outlet region a-C.
The following description will take an example of obtaining the outlet air temperature of the outlet air region a.
One air outlet temperature sensor or a plurality of air outlet temperature sensors can be arranged in the air outlet area A, and if a plurality of air outlet temperature sensors are arranged, the average value of a plurality of air outlet temperatures acquired by the plurality of air outlet temperature sensors can be taken as the air outlet temperature of the air outlet area A.
Similarly, the outlet air temperatures in the outlet air region B and the outlet air region C may be obtained separately.
S2: and acquiring a plurality of return air temperatures of a plurality of different return air areas corresponding to the return air inlet of the air conditioner between the columns.
In the present embodiment, the temperature of each of the return air sections D to F is collected by arranging a corresponding return air temperature sensor in each of the return air sections D to F.
The return air temperature in the return air area D will be described as an example.
The air return temperature sensor or the air return temperature sensors can be arranged in the air return area D, and if the air return temperature sensors are arranged, the average value of the air return temperatures collected by the air return temperature sensors can be taken as the air return temperature of the air return area D.
Similarly, the return air temperatures in the return air zone E and the return air zone F can be obtained separately.
[ obtaining the temperature difference between the Return air temperature and the Outlet air temperature ]
The air return region D corresponds to the air outlet region A, the air return region E corresponds to the air outlet region B, and the air return region F corresponds to the air outlet region C, so that the air return temperature of the air return region D corresponds to the air outlet temperature of the air outlet region A, the air return temperature of the air return region E corresponds to the air outlet temperature of the air outlet region B, and the air return temperature of the air return region F corresponds to the air outlet temperature of the air outlet region C.
The temperature difference Δ T1 relating to the cooling capacity of the outlet area a is the difference between the return air temperature of the return air area D and the outlet air temperature of the outlet area a.
The temperature difference Δ T2 relating to the cooling capacity of the outlet area B is the difference between the return air temperature of the return air area E and the outlet air temperature of the outlet area B.
The temperature difference Δ T3 relating to the cooling capacity of the outlet area C is the difference between the return air temperature of the return air area F and the outlet air temperature of the outlet area C.
[ air outlet volume of each air outlet region ]
With continued reference to fig. 1, in the present embodiment, four fans are longitudinally arranged along the height of the front door panel, and correspond to the air outlet areas a-C in sequence from top to bottom. In this embodiment, the four fans are identical in structure.
S3: and corresponding to each air outlet area A-C, determining the fans corresponding to each air outlet area A-C, and acquiring the air outlet volume of each air outlet area.
In this embodiment, there are three air outlet areas A/B/C, and there are four fans respectively labeled as fans F1-F4.
Considering that the four fans are longitudinally distributed, after the fans corresponding to the air outlet regions a to C are determined, some fans contribute to the air outlet volume of the adjacent upper and lower air outlet regions, and therefore, the air outlet volume of each air outlet region is obtained by weighting the air outlet volume in this embodiment. Determining that fans F1 and F2 correspond to an air outlet area A, fans F2 and F3 correspond to an air outlet area B, and fans F3 and F4 correspond to an air outlet area C.
The air outlet volume of each fan F1-F4 is in direct proportion to the third power of the air outlet rotating speed, and the correlation calculation of the air outlet volume and the air outlet rotating speed can be known by referring to the prior art. Therefore, the air outlet volume of each fan F1-F4 can be obtained according to the air outlet rotating speed of each fan. The air outlet rotating speeds of the fans F1-F4 are respectively V1-V4The corresponding air outlet volume is W1-W4.
Calculating the air outlet volume of each air outlet area A-C by using a weighting mode, wherein the air outlet volume of the air outlet area A is W1+1/3W2The air outlet quantity of the air outlet area B is 2/3W2+2/3W3The air outlet volume of the air outlet area C is 1/3W3+W4
At the beginning of the operation of the air conditioner between the rows, the air outlet rotating speed V1-V4The reference fan rotating speed V is set manually according to the requirements of the inter-row air conditioning system, and may be, for example, 70% of the duty ratio of the fan, and also determines the set total output air volume W = W1+W2+W3+W4
In the process of adjusting the rotating speed of the fans during the operation of the inter-train air conditioner, the total air outlet volume W' of the adjusted fans F1-F4 needs to be kept at the set total output volume W.
Similarly, if there are eight fans, they are longitudinally distributed on the front end outlet side.
Determining that the fans F1-F3 correspond to the air outlet area A, the fans F3-F6 correspond to the air outlet area B, and the fans F6-F8 correspond to the air outlet area C.
The air outlet rotating speeds of the fans F1-F8 are respectively V1-V8The corresponding air outlet volume is W1-W8.
Calculating the air outlet volume of each air outlet area A-C by using a weighting mode, wherein the air outlet volume of the air outlet area A is W1+W2+2/3W3The air outlet quantity of the air outlet area B is 1/3W3+W4+W5+1/3W6The air outlet volume of the air outlet area C is 2/3W6+W7+W8
S4: and calculating the actual refrigerating capacity of each air outlet area A-C in real time according to the air outlet quantity of each air outlet area A-C and the temperature difference between the return air temperature and the air outlet temperature.
According to the basic formula of the refrigerating capacity, the obtained air outlet amount and the obtained temperature difference, the actual refrigerating capacity corresponding to the air outlet areas A-C can be obtained.
S5: and adjusting the rotating speed of each corresponding fan in each air outlet area A-C in real time according to the actual refrigerating output and the required refrigerating output of each air outlet area A-C.
In the present embodiment, the cooling capacity required by each air outlet area a-C is the three conditions as described above.
In the adjusting process, the total air outlet volume W' of all the fans F1-F4 after adjustment needs to be kept consistent with the set total output air volume W. That is, when the cooling capacity demand in each of the outlet air areas a to C is not uniform, if the rotation speed of a certain fan is increased on the basis of the reference fan rotation speed V, the rotation speed of the fan must be decreased on the basis of the reference fan rotation speed V.
In the application, the control mode of the rotating speed of the air conditioner fans between the rows is divided into three modes according to the condition of the cooling capacity required by the air outlet areas A-C: a cold quantity balancing mode, a load association mode and an output balancing mode.
[ Cold quantity equalization mode ]
In the mode, the loads of the upper layer, the middle layer and the lower layer are uniformly arranged, so that the cold quantity required by each air outlet area A-C is the same.
And finely adjusting the output rotating speed of part of the fans according to the air outlet quantity calculated by the weighted value of the air outlet quantity of each fan corresponding to each air outlet area A-C and the temperature difference of each air outlet area A-C, so as to meet the output of the same cooling capacity in each air outlet area A-C.
This mode is often applied in cases where the load arrangement is uniform.
[ load correlation mode ]
The load conditions of different air outlet areas are determined according to the return air temperature, the greater the return air temperature is, the greater the load of the air outlet area is, and therefore the aim of the mode is to meet the condition that the return air temperature of each return air area is the same.
Real-time cooling capacity under different air outlet rotating speeds is calculated in real time through the air outlet temperature and the air outlet quantity of each air outlet area A-C, the rotating speed of each fan is adjusted, different cooling capacity outputs of different air outlet areas A-C are met, and the control aims are that the corresponding return air temperatures of the upper, middle and lower layers of return air areas are basically the same.
The mode is often applied to the conditions that the load arrangement is uneven and different air outlet areas need different cooling capacities.
For example, the load capacity of the middle area is large, the load capacity of the upper area and the lower area is small, and the temperature difference is reduced and the air outlet rotating speed is increased for the middle area under the condition that the return air temperature is the same.
[ output equalization mode ]
The mode takes the consistent air outlet temperature of each air outlet area A-C as a control target. In the mode, the return air temperature may be inconsistent, but the control purpose that the outlet air temperature of each outlet air area A-C is the same is met by adjusting the rotating speed of each fan in each outlet air area A-C.
According to the train air conditioner, the cold energy is output through targeted control, so that the loads in different air outlet areas have different cold energies, the cold energy output by the train air conditioner is used in a targeted manner, the waste of the cold energy is avoided, and the energy consumption of the whole train air conditioner is reduced.
In addition, in order to facilitate the use of multiple modes, buttons for switching the modes can be arranged on the train air conditioner, and when different demands for different output cooling capacities are met, one button can be selected to be switched to be directly executed.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
