Description
技术领域technical field
本发明属于空调器技术领域，具体涉及一种空调器除霜控制方法。The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner defrosting control method.
背景技术Background technique
空调器作为一种能够调节室内环境温度的设备，其工作原理为：通过制冷剂在循环管路之间通过高压/低压/气态/液态的状态转换来使室内环境温度降低或者升高，即从室内机的角度来看，空调器处于制冷或者制热工况。当空调器制热运行时，在一定的湿度条件下如果室外盘管温度过低会导致结霜情况，而室外盘管结霜会导致室外换热器的换热效率降低，影响空调器的制热效果，降低室内环境的舒适性，影响用户体验。因此，在空调器处于制热工况的情形下，需要对空调器的室外盘管进行及时而有效的除霜。As a device that can adjust the indoor ambient temperature, the air conditioner works on the principle that the indoor ambient temperature is reduced or increased through the high-pressure/low-pressure/gas/liquid state transition of the refrigerant between the circulation lines, that is, from From the perspective of the indoor unit, the air conditioner is in cooling or heating mode. When the air conditioner is in heating operation, if the temperature of the outdoor coil is too low under certain humidity conditions, it will cause frosting, and the frosting of the outdoor coil will reduce the heat exchange efficiency of the outdoor heat exchanger and affect the cooling performance of the air conditioner. The thermal effect reduces the comfort of the indoor environment and affects the user experience. Therefore, when the air conditioner is in a heating condition, timely and effective defrosting of the outdoor coil of the air conditioner is required.
现有的家用空调器在运行制热过程中，如果室外湿度较大，达到结霜的条件，室外机会结霜，而结霜直接影响的就是空调器的运行功率，即当外机存在结霜时，空调器的运行功率降低，导致室内制热量减小，直接影响室内的温度。现有的空调器一般是利用运行时间+室外盘管温度去判断是否进入除霜，但是这种方式并不能直接体现出室内温度的变化，真正影响用户感受的是室内温度。During the heating process of existing household air conditioners, if the outdoor humidity is high enough to meet the frosting conditions, frosting will occur outdoors, and the frosting will directly affect the operating power of the air conditioner, that is, when there is frosting on the outdoor unit At this time, the operating power of the air conditioner is reduced, resulting in a decrease in the indoor heating capacity, which directly affects the indoor temperature. Existing air conditioners generally use the running time + outdoor coil temperature to judge whether to enter defrosting, but this method cannot directly reflect the change of indoor temperature, and what really affects the user's experience is the indoor temperature.
基于此，特提出本发明。Based on this, the present invention is proposed.

具体实施方式Detailed ways
为使本发明的实施例、技术方案和优点更加明显，下面将结合附图对本发明的技术方案进行清楚、完整地描述，显然，所述的实施例是本发明的一部分实施例，而不是全部实施例。本领域技术人员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。In order to make the embodiments, technical solutions and advantages of the present invention more obvious, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Example. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.
如图1所示，本发明的空调器除霜控制方法包括下列步骤：S110、从空调器开机后第一次进入除霜模式开始，实时计算空调器的累计消耗功率W累计；S120、比较累计消耗功率W累计与预设消耗功率W，根据比较结果判断是否使空调器再次进入除霜模式。本领域技术人员能够理解的是，空调器从进入除霜到下一次再进入除霜为一个运行周期，该周期包括除霜运行和制热运行，如果空调器每次在恰当时机进行除霜，则空调器的一个运行周期内的累计消耗功率可以认为是固定的，即空调器在一个运行周期的累计消耗功率为预设消耗功率W。因此，从空调器开机后第一次进入除霜模式开始，通过计算空调器的累计消耗功率W累计，比较W累计和W的值即可准确地判断是否使空调器再次进入除霜模式。As shown in Figure 1, the air conditioner defrosting control method of the present invention comprises the following steps: S110, starting from the first time the air conditioner enters the defrosting mode after starting up, calculate the accumulated power consumption W of the air conditioner in real time; S120, compare the accumulated power The cumulative power consumption W is compared with the preset power consumption W, and it is judged whether to make the air conditioner enter the defrosting mode again according to the comparison result. Those skilled in the art can understand that an air conditioner is an operating cycle from entering defrosting to the next defrosting, and this cycle includes defrosting operation and heating operation. If the air conditioner performs defrosting at an appropriate time each time, Then the accumulative power consumption of the air conditioner in one operating cycle can be considered as fixed, that is, the accumulative power consumption of the air conditioner in one operating cycle is the preset power consumption W. Therefore, from the first time the air conditioner enters the defrosting mode after it is turned on, by calculating the accumulated power consumption W of the air conditioner, and comparing the W accumulation with the value of W, it can be accurately judged whether to make the air conditioner enter the defrosting mode again.
作为示例，关于预设消耗功率W可以通过以下方式确定：首先设定进入除霜的判断条件，如根据室外机盘管的温度来设定使空调器进入除霜模式的条件。当满足判断条件时，使空调器进入除霜模式，然后计算空调器的累计消耗功率Wn，当再次满足判断条件时，将当前计算的累计消耗功率Wn保存为W1；接着从空调器进入除霜模式开始，重新计算空调器的累计消耗功率Wn，当再一次满足判断条件时，将当前计算的累计消耗功率Wn保存为W2；依次类推可以计算空调器在相邻两次进入除霜模式之间的累计消耗功率W1、W2、W3…Wn；然后计算累计消耗功率W1、W2、W3…Wn的平均值W，该平均值Q即为预设消耗功率。As an example, the preset power consumption W can be determined in the following manner: firstly, setting the judgment condition for entering defrosting, such as setting the condition for making the air conditioner enter the defrosting mode according to the temperature of the outdoor unit coil. When the judgment condition is satisfied, the air conditioner enters the defrosting mode, and then the cumulative power consumption W n of the air conditioner is calculated, and when the judgment condition is met again, the current calculated cumulative power consumption W n is saved as W 1 ; After entering the defrosting mode, recalculate the accumulative power consumption W n of the air conditioner. When the judgment condition is met again, save the currently calculated accumulative power consumption W n as W 2 ; The cumulative power consumption W 1 , W 2 , W 3 ...W n between entering the defrosting mode; then calculate the average value W of the cumulative power consumption W 1 , W 2 , W 3 ...W n , and the average value Q is the preset Set power consumption.
本领域技术人员能够理解的是，空调器的累计消耗功率可以通过积分的方式计算，在此不再对详细的计算方式进行说明。通过试验得出多组空调器在每个运行周期(空调器从进入除霜到下一次再进入除霜为一个运行周期)的累计消耗功率，试验得到的数据越多则预设消耗功率W越准确。另外，关于在试验过程中设定的除霜的判断条件可以灵活地选用任意合理的判断条件，这些都不脱离本发明的保护范围。Those skilled in the art can understand that the cumulative power consumption of the air conditioner can be calculated in an integral manner, and the detailed calculation manner will not be described here. Through the test, the accumulated power consumption of multiple groups of air conditioners in each operation cycle (the air conditioner enters the defrosting to the next defrosting is one operation cycle), the more data obtained from the test, the higher the preset power consumption W precise. In addition, with regard to the judging conditions for defrosting set during the test, any reasonable judging conditions can be flexibly selected, and these do not depart from the protection scope of the present invention.
在步骤S120中，当0.9W≤W累计＜W时，此时可以降低压缩机运行频率，继续制热运行，例如将压缩机运行频率降低20％，可以延缓进入除霜的时间。当W累计≥W，说明空调器的累计消耗功率达到了预设消耗功率W，即可以进行除霜，此时使空调器再次进入除霜模式。In step S120, when 0.9W≤Wcumulative <W, the compressor operation frequency can be reduced to continue heating operation, for example, the compressor operation frequency can be reduced by 20% to delay the defrosting time. When the cumulative W ≥ W, it means that the cumulative power consumption of the air conditioner has reached the preset power consumption W, that is, the defrosting can be performed, and the air conditioner enters the defrosting mode again at this time.
需要说明的是，在步骤S110中，空调器开机后第一次进入除霜模式的时间可以为预设时间。例如由设计人员根据空调器的机型和空调器应用场景的外界环境温度和湿度值，然后通过试验获得空调器开机后第一次进入除霜模式的时间。举例而言，使空调器运行于目标环境中，观察空调器的结霜情况，然后记录进入除霜的时间以及对应的空调器的型号、外界环境温度和湿度值的数据，可以通过进行多组试验获得的数据最终确定空调器在开机后第一次进入除霜的时间。本领域技术人员还可以灵活地选择其他合理的试验方法以获得空调器开机后第一次进入除霜的时间，在此不再进行详细说明。It should be noted that, in step S110, the time when the air conditioner enters the defrosting mode for the first time after starting up may be a preset time. For example, the designer obtains the time when the air conditioner enters the defrosting mode for the first time after the air conditioner is turned on, according to the air conditioner model and the external ambient temperature and humidity values of the air conditioner application scene through experiments. For example, let the air conditioner run in the target environment, observe the frosting condition of the air conditioner, and then record the time of defrosting and the corresponding data of the air conditioner model, external environment temperature and humidity value. The data obtained from the test finally determine the time when the air conditioner enters defrosting for the first time after it is turned on. Those skilled in the art can flexibly choose other reasonable test methods to obtain the time when the air conditioner enters defrosting for the first time after it is turned on, and no detailed description will be given here.
作为示例，本发明的空调器除霜控制方法采用停机除霜方式，即当满足进入除霜模式的条件时，通过四通阀换向进行除霜。每次除霜的时间设定为固定时间。由于在该除霜模式下，空调器不进行制热，此时空调器不消耗功率，因此可以在第一次除霜模式结束后再开始计算空调器的累计消耗功率W累计。本领域技术人员容易理解的是，在该模式下，由于除霜模式下的累计消耗功率为0，因此即使从进入除霜模式开始就计算空调器的累计消耗功率Q累计，也不会影响判断结果。As an example, the defrosting control method of the air conditioner of the present invention adopts the shutdown defrosting mode, that is, when the conditions for entering the defrosting mode are met, the four-way valve is switched to perform defrosting. The time of each defrosting is set as a fixed time. Since in this defrosting mode, the air conditioner does not perform heating, the air conditioner does not consume power at this time, so the cumulative power consumption W of the air conditioner can be calculated after the end of the first defrosting mode. Those skilled in the art can easily understand that in this mode, since the cumulative power consumption in the defrosting mode is 0, even if the cumulative power consumption Q of the air conditioner is calculated from the beginning of entering the defrosting mode, it will not affect the judgment result.
作为示例，如果本发明的空调器除霜控制方法采用不停机除霜方式，即当满足进入除霜模式的条件时，开启旁通管路进行除霜，即空调器在对室内进行制热的同时，利用旁通管路对室外机进行除霜。此时由于在空调器在除霜模式下仍然有一部分的制热量，即会消耗一部分功率，因此可以在第一次除霜模式开始时计算空调器的累计消耗功率W累计。本领域技术人员可以理解的是，如果在确定预设消耗功率W时不考虑除霜模式下空调器消耗的功率，则在采用不停机除霜方式时，也可以在除霜模式结束后再开始计算空调器的累计消耗功率W累计。As an example, if the air conditioner defrosting control method of the present invention adopts the non-stop defrosting method, that is, when the conditions for entering the defrosting mode are met, the bypass pipeline is opened for defrosting, that is, the air conditioner is heating the room. At the same time, use the bypass pipeline to defrost the outdoor unit. At this time, since the air conditioner still has a part of heating capacity in the defrosting mode, that is, it will consume a part of power, so the cumulative power consumption W of the air conditioner can be calculated when the first defrosting mode starts. Those skilled in the art can understand that if the power consumed by the air conditioner in the defrosting mode is not taken into account when determining the preset power consumption W, the non-stop defrosting mode can also be started after the defrosting mode ends. The cumulative power consumption W cumulative of the air conditioner is calculated.
综上所述，本发明通过计算空调器的累计消耗功率W累计，并与预设消耗功率W进行比较，从而判断空调器的累计消耗功率W累计是否达到需要再次进行除霜的程度。将预设消耗功率W作为基准可以更准确地判断出空调器进入除霜模式的时机，避免频繁除霜现象。并且根据空调器的累计消耗功率能够在最大程度上减小除霜过程中对室内温度的影响，使室内温度不会出现较大的波动。To sum up, the present invention calculates the cumulative power consumption W of the air conditioner and compares it with the preset power consumption W, so as to determine whether the cumulative power consumption W of the air conditioner reaches the level that needs to be defrosted again. Taking the preset power consumption W as a benchmark can more accurately determine the timing when the air conditioner enters the defrosting mode, and avoid frequent defrosting. And according to the accumulative power consumption of the air conditioner, the impact on the indoor temperature during the defrosting process can be reduced to the greatest extent, so that the indoor temperature will not fluctuate greatly.
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings, but those skilled in the art will easily understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
