技术领域Technical field
本发明涉及空调装置领域，具体而言，涉及一种空调加热系统的控制方法、一种空调加热系统的控制装置、一种空调器、一种计算机设备、一种计算机可读存储介质。The present invention relates to the field of air conditioning devices, and in particular to a method for controlling an air conditioning heating system, a control device for an air conditioning heating system, an air conditioner, a computer device, and a computer readable storage medium.
背景技术Background technique
随着人们生活水平的提高和节能意识的增强，空调以其节能，控制灵活，容易安装和维护等特点，已走进广大普通家庭，并得到越来越广泛的应用。然而在低温状态下，由于蒸发温度比较低，蒸发器容易结霜等因素，为保证空调机组稳定可靠地运行，必须进行除霜。除霜过程中会形成大量冷凝水，正常情况下可以通过机组底盘上的排水孔排除，在环境温度比较低的时候，往往除霜一结束，机组换热器及底盘温度马上降低，来不及排放干净的冷凝水，聚集在底盘累积成冰，严重时会造成底盘排水孔堵死，影响之后的除霜冷凝水的正常排放，甚至会波及到换热器底部的换热效果，从而影响整个空调系统使用效果和运行的可靠性。现有技术中，为解决上述问题，在底盘增设加热装置，在温度较低且空调处于制热模式时，对底盘进行加热。然而，在空调制热模式结束运行后，如果同时停止对底盘的加热，则残余在底盘中没有排放干净的冷凝水会在低温环境下迅速结冰，影响之后的除霜冷凝水的正常排放。With the improvement of people's living standards and the awareness of energy conservation, air conditioners have entered the vast family of ordinary households with their characteristics of energy saving, flexible control, easy installation and maintenance, and have been widely used. However, in the low temperature state, since the evaporation temperature is relatively low, the evaporator is prone to frosting and the like, and in order to ensure stable and reliable operation of the air conditioning unit, defrosting must be performed. During the defrosting process, a large amount of condensed water will be formed. Under normal circumstances, it can be removed through the drainage hole on the unit chassis. When the ambient temperature is relatively low, the temperature of the heat exchanger and the chassis will be reduced immediately after the defrosting is completed. The condensed water accumulates in the chassis and accumulates into ice. In severe cases, the drainage hole of the chassis is blocked, which affects the normal discharge of the defrost condensate afterwards, and even affects the heat transfer effect at the bottom of the heat exchanger, thereby affecting the entire air conditioning system. Use effects and operational reliability. In the prior art, in order to solve the above problem, a heating device is added to the chassis, and the chassis is heated when the temperature is low and the air conditioner is in the heating mode. However, after the end of the air-conditioning heating mode, if the heating of the chassis is stopped at the same time, the residual condensed water that is not discharged in the chassis will freeze rapidly in a low temperature environment, affecting the normal discharge of the subsequent defrost condensate.
因此，如何防止空调处于制热模式或停止制热模式后，残余在空调的机组底盘中的冷凝水结冰影响排放成为亟待解决的问题。 Therefore, how to prevent the condensation of condensed water in the chassis of the air conditioner from being affected by the air conditioner in the heating mode or the stop of the heating mode becomes an urgent problem to be solved.

具体实施方式detailed description
为了能够更清楚地理解本发明的上述目的、特征和优点，下面结合附图和具体实施方式对本发明进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。The present invention will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.
在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是，本发明还可以采用其他不同于在此描述的其他方式来实施，因此，本发明的保护范围并不受下面公开的具体实施例的限制。In the following description, numerous specific details are set forth in order to provide a full understanding of the invention, but the invention may be practiced otherwise than as described herein. Limitations of the embodiments.
图1示出了根据本发明的第一个实施例的空调加热系统的控制方法的示意流程图。Fig. 1 shows a schematic flow chart of a control method of an air conditioning heating system according to a first embodiment of the present invention.
如图1所示，根据本发明的第一个实施例的空调加热系统的控制方法，包括：步骤S102，检测室外温度；步骤S104，在室外温度低于第一预设温度阈值且空调处于制热模式或制热模式的停止运行时间小于预设时间阈值时，控制空调的底盘电热器进行加热。As shown in FIG. 1 , a method for controlling an air conditioning heating system according to a first embodiment of the present invention includes: step S102, detecting an outdoor temperature; and step S104, the outdoor temperature is lower than a first preset temperature threshold and the air conditioner is in a system When the stop mode of the hot mode or the heating mode is less than the preset time threshold, the chassis electric heater that controls the air conditioner is heated.
如果在步骤S102中用于检测室外温度的温度传感器出现故障，就不能得知空调制热过程中，因为除霜造成的冷凝水是否会结冰堵塞排水孔。因此，为了防止空调在不能检测室外温度的情况下，冷凝水结冰堵塞排水孔，对空调机组的制热效果和运行可靠性造成影响，则此时还判定空调处于故障状态，控制空调停止运行。此外，还控制空调发出报警信息，用以 提示用户空调发生故障以及故障的来源，便于用户进行进一步的处理。If the temperature sensor for detecting the outdoor temperature fails in step S102, it is impossible to know whether or not the condensed water caused by the defrosting will freeze and block the drain hole during the air-conditioning heating process. Therefore, in order to prevent the air conditioner from being able to detect the outdoor temperature, the condensed water freezes and blocks the drain hole, which affects the heating effect and operational reliability of the air conditioning unit. At this time, it is also determined that the air conditioner is in a fault state, and the air conditioner is stopped. . In addition, it also controls the air conditioner to send an alarm message for It prompts the user to malfunction and the source of the fault, which is convenient for the user to carry out further processing.
在步骤S104中，对空调的机组底盘进行加热过程中，如果检测到室外温度不低于第二预设温度阈值或空调制热模式停止运行时间超过预设时间阈值，则控制停止底盘电热器对机组底盘加热。也就是说，如果在温度低于一定值时，空调制热模式停止运行时间超出一定时间，则认为在一定时间内，对机组底盘的加热足以使可能残余的冷凝水正常排出机组底盘，因此在超出该时间后，停止底盘电热器对机组底盘的加热，这样，可以保证在不会造成冷凝水冰堵的同时，节省电能。此外，在底盘电热器对机组底盘进行加热过程中，如果检测到室外温度提升到第二预设温度阈值以上，冷凝水在该温度下不会发生结冰现象，也就不会造成底盘排水孔堵塞的情况，此时也停止底盘电热器对机组底盘的加热。In step S104, during the heating process of the unit chassis of the air conditioner, if it is detected that the outdoor temperature is not lower than the second preset temperature threshold or the air conditioning heating mode stop running time exceeds the preset time threshold, then the control stops the chassis electric heater pair. The unit chassis is heated. That is to say, if the air-conditioning heating mode is stopped for a certain period of time when the temperature is lower than a certain value, it is considered that the heating of the unit chassis is sufficient for the residual condensate to be normally discharged from the unit chassis within a certain period of time, so After this time is exceeded, the heating of the chassis of the chassis by the chassis electric heater is stopped, so that the electric energy can be saved without causing condensed water ice blockage. In addition, in the process of heating the chassis of the unit by the chassis electric heater, if it is detected that the outdoor temperature rises above the second preset temperature threshold, the condensed water does not freeze at the temperature, and the chassis drain hole is not caused. In the case of blockage, the heating of the chassis of the unit by the chassis heater is also stopped.
在本实施例中，根据步骤S102中检测到的室外温度与预设温度阈值的比较，步骤S104判断空调是否处于制热模式或制热模式结束的时间是否超出预设的时间，来确定是否对机组底盘进行加热。如果空调处于制热模式或制热模式结束时间不够长，且温度低于第一预设温度阈值，则空调的机组底盘内可能存在残余的冷凝水会结冰，影响之后的冷凝水排出。因此，如果温度低于第一预设温度阈值，则在空调处于制热模式或在空调制热模式结束一段时间内，对机组底盘进行加热，能够防止空调停止制热模式后，残余在空调的机组底盘中的冷凝水结冰，影响之后冷凝水的排放，进而防止对换热器底部的换热效果造成影响，提高整个空调系统使用效果和运行的可靠性。In this embodiment, according to the comparison between the outdoor temperature detected in step S102 and the preset temperature threshold, step S104 determines whether the air conditioner is in the heating mode or the time when the heating mode ends exceeds a preset time to determine whether The unit chassis is heated. If the air conditioner is in the heating mode or the heating mode end time is not long enough, and the temperature is lower than the first preset temperature threshold, residual condensed water may be frozen in the air conditioner unit chassis, which may affect the subsequent condensed water discharge. Therefore, if the temperature is lower than the first preset temperature threshold, the unit chassis is heated while the air conditioner is in the heating mode or in the air conditioning heating mode for a period of time, which can prevent the air conditioner from remaining in the air conditioner after stopping the heating mode. The condensed water in the chassis of the unit freezes, which affects the discharge of the condensed water afterwards, thereby preventing the heat transfer effect on the bottom of the heat exchanger and improving the use effect and reliability of the entire air conditioning system.
图2示出了根据本发明的第二个实施例的空调加热系统的控制装置的示意框图。Fig. 2 is a schematic block diagram showing a control device of an air conditioning heating system according to a second embodiment of the present invention.
如图2所示，根据本发明的第二个实施例的空调加热系统的控制装置200，包括：温度检测单元202，用于检测室外温度；控制单元204，用于在室外温度低于第一预设温度阈值且空调处于制热模式或制热模式的停止运行时间小于预设时间阈值，控制空调的底盘电热器进行加热。As shown in FIG. 2, the control device 200 of the air conditioning heating system according to the second embodiment of the present invention includes: a temperature detecting unit 202 for detecting an outdoor temperature; and a control unit 204 for lowering the outdoor temperature. The preset temperature threshold and the stoppage time of the air conditioner in the heating mode or the heating mode are less than the preset time threshold, and the chassis electric heater of the air conditioner is controlled to be heated.
根据温度检测单元202控制空调检测到的室外温度与预设温度阈值的比较，控制单元204判断是否处于制热模式或制热模式结束的时间是否小 于预设的时间，并根据判断结果，控制空调的底盘电热器对机组底盘进行加热。如果空调处于制热模式或制热模式结束时间不够长，且温度低于一定值，则空调的机组底盘内可能存在残余的冷凝水会结冰，影响之后的冷凝水排出。因此，如果温度低于一定值，则在空调制热模式结束一段时间内，控制单元204控制空调的底盘电热器对机组底盘进行加热，能够防止空调处于制热模式或停止制热模式后，残余在空调的机组底盘中的冷凝水结冰，影响之后冷凝水的排放，进而防止对换热器底部的换热效果造成影响，提高整个空调系统使用效果和运行的可靠性。According to the temperature detecting unit 202 controlling the comparison between the outdoor temperature detected by the air conditioner and the preset temperature threshold, the control unit 204 determines whether the heating time or the heating mode end time is small. At a preset time, and according to the judgment result, the chassis electric heater of the air conditioner is controlled to heat the unit chassis. If the air conditioner is in the heating mode or the heating mode end time is not long enough, and the temperature is lower than a certain value, there may be residual condensed water in the air conditioning unit chassis that will freeze, which will affect the subsequent condensed water discharge. Therefore, if the temperature is lower than a certain value, the control unit 204 controls the chassis electric heater of the air conditioner to heat the chassis of the unit during the period of the end of the air conditioning heating mode, thereby preventing the air conditioner from being in the heating mode or stopping the heating mode, and remaining The condensed water in the chassis of the air conditioner is frozen, which affects the discharge of the condensed water afterwards, thereby preventing the heat exchange effect on the bottom of the heat exchanger, and improving the use effect and reliability of the entire air conditioning system.
此外，还包括：故障检测单元206，用于检测温度检测单元是否故障，如果空调用于检测室外温度的温度检测单元202出现故障，就不能得知空调制热过程中，因为除霜造成的冷凝水是否会结冰堵塞排水孔，因此，为了防止空调在温度检测单元202出现故障的情况下，冷凝水结冰堵塞排水孔，对空调机组的制热效果和运行可靠性造成影响，此时故障检测单元206判定空调处于故障状态，控制空调停止运行。In addition, the method further includes: a fault detecting unit 206, configured to detect whether the temperature detecting unit is faulty, and if the air temperature detecting unit 202 for detecting the outdoor temperature is faulty, the air conditioning heating process cannot be known because of condensation caused by defrosting. Whether the water will freeze and block the drainage hole, therefore, in order to prevent the air conditioner from damaging the temperature detecting unit 202, the condensed water freezes and blocks the drainage hole, which affects the heating effect and operational reliability of the air conditioning unit. The detecting unit 206 determines that the air conditioner is in a fault state, and controls the air conditioner to stop operating.
具体地，控制单元204还用于在温度低于一定值时，如果在对机组底盘进行加热过程中，检测到空调制热模式的停止运行时间超过预设时间阈值，则认为在该时间内，控制单元204控制空调的底盘电热器对机组底盘的加热足以使可能残余的冷凝水正常排出机组底盘，因此在超出该时间后，控制单元204控制空调停止对机组底盘加热，这样，可以保证在不会造成冷凝水冰堵的同时，节省电能。Specifically, the control unit 204 is further configured to: when the temperature is lower than a certain value, if the stop running time of the air conditioning heating mode is detected to exceed the preset time threshold during heating of the chassis of the unit, it is considered that during the time, The control unit 204 controls the chassis electric heater of the air conditioner to heat the chassis of the unit enough to cause the residual condensed water to be normally discharged out of the unit chassis. Therefore, after the time is exceeded, the control unit 204 controls the air conditioner to stop heating the unit chassis, so that it can be guaranteed. It will cause condensate water to block while saving energy.
控制单元204还用于在空调对机组底盘进行加热过程中，检测到室外温度提升到第二预设温度阈值以上时，冷凝水在该温度下不会发生结冰现象，也就不会造成底盘排水孔堵塞的情况，此时控制单元204控制空调的底盘电热器停止对机组底盘加热，可以节省电能。The control unit 204 is further configured to: during the heating process of the air conditioner to the chassis of the unit, when the outdoor temperature is raised above the second preset temperature threshold, the condensed water does not freeze at the temperature, and the chassis is not caused. When the drain hole is blocked, the control unit 204 controls the chassis electric heater of the air conditioner to stop heating the unit chassis, thereby saving power.
除此之外，空调加热系统的控制装置200还包括报警单元208，用于在确定温度检测单元202故障的情况下，发出报警信息。如果温度检测单元202出现故障，就不能得知空调制热过程中，因为除霜造成的冷凝水是否会结冰堵塞排水孔，因此，为了防止空调在不能检测室外温度的情况下，冷凝水结冰堵塞排水孔，对空调机组的制热效果和运行可靠性造成影 响，则报警单元208发出报警信息，用以提示用户空调发生故障以及故障的来源，便于用户进行进一步的处理。In addition to this, the control device 200 of the air conditioning heating system further includes an alarm unit 208 for issuing an alarm message in the event that it is determined that the temperature detecting unit 202 is malfunctioning. If the temperature detecting unit 202 fails, it is impossible to know whether the condensed water caused by the defrosting will freeze and block the drain hole during the air conditioning heating process. Therefore, in order to prevent the air conditioner from detecting the outdoor temperature, the condensed water knot is prevented. The ice blocks the drainage hole, which affects the heating effect and operational reliability of the air conditioning unit. When the alarm is sounded, the alarm unit 208 sends an alarm message to prompt the user to malfunction and the source of the fault, so that the user can perform further processing.

Whether the time in which the heating mode or the heating mode ends exceeds the preset time to determine whether to heat the unit chassis. If the end time of the air conditioning heating mode is not long enough and the temperature is lower than the first preset temperature threshold, residual condensed water may be frozen in the chassis of the air conditioner, which may affect the subsequent condensed water discharge.
