Description
技术领域Technical Field
本发明涉及空调技术领域,具体而言,涉及一种空气能热泵热水机的控制方法及装置。The present invention relates to the technical field of air conditioning, and in particular to a control method and device for an air energy heat pump water heater.
背景技术Background technique
空气能热泵热水机通常包括空调、水模块、地暖及换热片,随着空气能热泵热水机日益普及,越来越多的用户使用空气能热泵热水机作为家庭供暖的主要设备。为了保证热泵热水机出水温度稳定,通常在水模块的热水出水口与供热设备之间安装平衡水箱,平衡水箱的实际出水温度更能体现末端供热设备的实际进水温度情况,从而可以根据平衡水箱的实际出水温度情况分配各末端供热设备的供热需求。但是,在实际使用过程中,空气能热泵热水机中的关键温度传感器出现故障时,容易导致系统无法正常工作,诸如平衡水箱中检测水温的传感器出现故障问题时无法检测出平衡水箱的实际出水温度,进而无法恒量末端供热设备的供热需求分配,无法满足用户的应急使用需求,降低了用户体验。Air-energy heat pump water heaters usually include air conditioners, water modules, floor heating and heat exchangers. With the increasing popularity of air-energy heat pump water heaters, more and more users use air-energy heat pump water heaters as the main equipment for home heating. In order to ensure the stability of the outlet water temperature of the heat pump water heater, a balancing water tank is usually installed between the hot water outlet of the water module and the heating equipment. The actual outlet water temperature of the balancing water tank can better reflect the actual inlet water temperature of the terminal heating equipment, so that the heating demand of each terminal heating equipment can be allocated according to the actual outlet water temperature of the balancing water tank. However, in actual use, when a key temperature sensor in the air-energy heat pump water heater fails, it is easy to cause the system to fail to work properly. For example, when the sensor for detecting water temperature in the balancing water tank fails, the actual outlet water temperature of the balancing water tank cannot be detected, and the heating demand distribution of the terminal heating equipment cannot be constant, and the emergency use needs of users cannot be met, which reduces the user experience.

本实施例提供了一种空气能热泵热水机,参见如图1所示的空气能热泵热水机结构示意图,该空气能热泵热水机包括:室外机11、水模块12、多个末端供热设备、平衡水箱13及控制器(图中未示出),平衡水箱13设置于室外机11与末端供热设备之间,水模块12设置于室外机11与平衡水箱13之间,平衡水箱13中设置有温度传感器。The present embodiment provides an air energy heat pump water heater, referring to the structural schematic diagram of the air energy heat pump water heater as shown in FIG1 , the air energy heat pump water heater comprises: an outdoor unit 11, a water module 12, a plurality of terminal heating devices, a balancing water tank 13 and a controller (not shown in the figure), the balancing water tank 13 is arranged between the outdoor unit 11 and the terminal heating device, the water module 12 is arranged between the outdoor unit 11 and the balancing water tank 13, and a temperature sensor is arranged in the balancing water tank 13.
上述水模块12用于将机组管道中的水与室外机11进入水模块12中的冷媒进行换热,以提升水温,加热后的水经过水模块12的出水总阀门121进入出水管道,进而经过平衡水箱13后进入各个末端供热设备。The above-mentioned water module 12 is used to exchange heat between the water in the unit pipeline and the refrigerant entering the water module 12 from the outdoor unit 11 to increase the water temperature. The heated water enters the water outlet pipeline through the main water outlet valve 121 of the water module 12, and then enters each terminal heating equipment after passing through the balancing water tank 13.
如图1所示,图1中的深灰色管道为水模块12的出水管道(也即各末端供热设备的进水管道),图1中的浅灰色管道为水模块的回水管道,即在各末端供热设备中散热后的回水,回水管道中的水经过水模块12的回水总阀门122后进入水模块中与冷媒进行换热,吸收冷媒的热量。As shown in Figure 1, the dark gray pipe in Figure 1 is the outlet pipe of the water module 12 (that is, the water inlet pipe of each terminal heating device), and the light gray pipe in Figure 1 is the return pipe of the water module, that is, the return water after heat dissipation in each terminal heating device. The water in the return pipe passes through the return water main valve 122 of the water module 12 and then enters the water module to exchange heat with the refrigerant to absorb the heat of the refrigerant.
如图1所示,水模块12中设置有循环水泵P1,以使管道中的水充分循环。水模块12的出水管道上还设置有排水阀123,回水管道上设置有补水阀124。以平衡水箱中设置两个温度传感器为例,平衡水箱13的上部设置有第一温度传感器BT1,下部设置有第二温度传感器BT2。As shown in FIG1 , a circulating water pump P1 is provided in the water module 12 to fully circulate the water in the pipe. A drain valve 123 is also provided on the outlet pipe of the water module 12, and a water replenishment valve 124 is provided on the return pipe. Taking the example of two temperature sensors provided in the balancing water tank, a first temperature sensor BT1 is provided on the upper part of the balancing water tank 13, and a second temperature sensor BT2 is provided on the lower part.
上述末端供热设备包括室内机14、换热片15和地暖16,本实施例提供的空气能热泵热水机还可以包括热水水箱17,热水水箱17中的水可以使用太阳能电池板进行加热,还可以进入水模块12中与冷媒进行换热,并存储用户的生活用水。The above-mentioned terminal heating equipment includes an indoor unit 14, a heat exchange plate 15 and a floor heating 16. The air-source heat pump water heater provided in this embodiment may also include a hot water tank 17. The water in the hot water tank 17 can be heated using a solar panel, and can also enter the water module 12 to exchange heat with the refrigerant and store the user's domestic water.
如图1所示,热水水箱17的连接管道上设置有外循环泵P2,地暖与平衡水箱之间的进水管道上设置有地暖水泵P3、控制阀门MV2及地暖进水水温传感器FLH。As shown in FIG1 , an external circulation pump P2 is provided on the connecting pipe of the hot water tank 17 , and a floor heating water pump P3 , a control valve MV2 and a floor heating water inlet temperature sensor FLH are provided on the water inlet pipe between the floor heating and the balancing water tank.
本实施例提供了一种空气能热泵热水机的控制方法,该方法可以应用于上述实施例提供的空气能热泵热水机,参见如图2所示的空气能热泵热水机的控制方法流程图,该方法主要包括以下步骤S202~步骤S208:This embodiment provides a control method for an air energy heat pump water heater, which can be applied to the air energy heat pump water heater provided in the above embodiment. Referring to the control method flow chart of the air energy heat pump water heater shown in FIG. 2 , the method mainly includes the following steps S202 to S208:
步骤S202:获取温度传感器的使能状态;Step S202: obtaining the enabling status of the temperature sensor;
温度传感器的使能状态包括启用状态和未启用状态,即在控制过程中是否会使用温度传感器的温度检测值,上述温度传感器在启用状态和未启用状态下均可以检测平衡水箱中的水温。The enabling state of the temperature sensor includes an enabled state and a disabled state, that is, whether the temperature detection value of the temperature sensor will be used in the control process. The above-mentioned temperature sensor can detect the water temperature in the balancing water tank in both the enabled state and the disabled state.
步骤S204:基于温度传感器的使能状态确定平衡水箱的等效水温及等效水温检测状态;Step S204: determining the equivalent water temperature and equivalent water temperature detection state of the balancing water tank based on the enabling state of the temperature sensor;
上述等效水温检测状态包括故障状态和正常状态;等效水温检测状态与平衡水箱中的温度传感器的当前状态相关。上述平衡水箱中的温度传感器的数量可以是一个或多个,当平衡水箱中的温度传感器存在开路或短路问题时,确定该温度传感器处于故障状态。The above-mentioned equivalent water temperature detection state includes a fault state and a normal state; the equivalent water temperature detection state is related to the current state of the temperature sensor in the balancing water tank. The number of the temperature sensors in the above-mentioned balancing water tank can be one or more. When the temperature sensor in the balancing water tank has an open circuit or a short circuit problem, it is determined that the temperature sensor is in a fault state.
当平衡水箱中存在未处于故障状态(即处于正常状态)的温度传感器时,则可以正常检测平衡水箱的等效水温,确定平衡水箱的等效水温检测状态为正常状态,根据正常状态的温度传感器检测的水温确定平衡水箱的等效水温。When there is a temperature sensor in the balancing water tank that is not in a faulty state (i.e., in a normal state), the equivalent water temperature of the balancing water tank can be detected normally, and the equivalent water temperature detection state of the balancing water tank is determined to be a normal state. The equivalent water temperature of the balancing water tank is determined based on the water temperature detected by the temperature sensor in the normal state.
步骤S206:基于温度传感器的使能状态、平衡水箱的等效水温及等效水温检测状态确定平衡水箱的等效实际出水温度;Step S206: determining the equivalent actual outlet water temperature of the balancing water tank based on the enabling state of the temperature sensor, the equivalent water temperature of the balancing water tank and the equivalent water temperature detection state;
当温度传感器的使能状态为启用状态时,根据平衡水箱的等效水温及等效水温检测状态确定平衡水箱的等效实际出水温度,该等效实际出水温度可以反映各个末端供热设备的进水温度,从而可以恒量末端供热设备的供热需求。When the enabling state of the temperature sensor is enabled, the equivalent actual water outlet temperature of the balancing water tank is determined according to the equivalent water temperature of the balancing water tank and the equivalent water temperature detection state. The equivalent actual water outlet temperature can reflect the inlet water temperature of each terminal heating equipment, thereby the heating demand of the terminal heating equipment can be constant.
当温度传感器的使能状态为未启用状态时,需要根据其他温度传感器检测到的水温,诸如水模块的进水水温或回水水温,确定平衡水箱的等效实际出水温度。When the enabling state of the temperature sensor is not enabled, it is necessary to determine the equivalent actual outlet water temperature of the balancing water tank according to the water temperature detected by other temperature sensors, such as the inlet water temperature or the return water temperature of the water module.
步骤S208:获取末端供热设备的设定温度,基于平衡水箱的等效实际出水温度及设定温度对末端供热设备进行开停机控制。Step S208: Obtain the set temperature of the terminal heating equipment, and control the start and stop of the terminal heating equipment based on the equivalent actual water outlet temperature of the balancing water tank and the set temperature.
上述末端供热设备可以包括空调的室内机、换热片(即暖气片)及地暖,上述设定温度可以是各末端供热设备为实现室内供热所需的水温,各末端供热设备的设定温度可能相同或不同。由于上述平衡水箱的等效实际出水温度近似为进入室内机及换热片的实际水温,判断该等效实际出水温度与室内机及换热片的设定温度的关系,当等效实际出水温度低于设定温度时,即进入末端供热设备的水温较低,不满足供热需求,需要提升平衡水箱的等效实际出水温度,控制室外机开机运行,以增加系统中水温的换热速度提升平衡水箱的等效实际出水温度。The terminal heating equipment may include the indoor unit of the air conditioner, the heat exchanger (i.e., radiator) and floor heating. The set temperature may be the water temperature required by each terminal heating equipment to achieve indoor heating. The set temperature of each terminal heating equipment may be the same or different. Since the equivalent actual water outlet temperature of the above-mentioned balancing water tank is approximately the actual water temperature entering the indoor unit and the heat exchanger, the relationship between the equivalent actual water outlet temperature and the set temperature of the indoor unit and the heat exchanger is determined. When the equivalent actual water outlet temperature is lower than the set temperature, that is, the water temperature entering the terminal heating equipment is low and does not meet the heating demand, it is necessary to increase the equivalent actual water outlet temperature of the balancing water tank, and control the outdoor unit to start up and run, so as to increase the heat exchange rate of the water temperature in the system and increase the equivalent actual water outlet temperature of the balancing water tank.
在一种具体的实施方式中,上述末端供热设备包括地暖、室内机和换热片;当平衡水箱的等效实际出水温度小于设定温度时,控制室外机及水模块开机运行,以增大平衡水箱的等效实际出水温度;当平衡水箱的等效实际出水温度大于设定温度时,控制室外机及水模块停止运行,以减小平衡水箱的等效实际出水温度。In a specific embodiment, the terminal heating equipment includes floor heating, an indoor unit and a heat exchanger; when the equivalent actual water outlet temperature of the balancing water tank is lower than the set temperature, the outdoor unit and the water module are controlled to start and operate to increase the equivalent actual water outlet temperature of the balancing water tank; when the equivalent actual water outlet temperature of the balancing water tank is higher than the set temperature, the outdoor unit and the water module are controlled to stop operating to reduce the equivalent actual water outlet temperature of the balancing water tank.
通过根据平衡水箱的等效实际出水温度与末端供热设备的设定温度的大小关系控制室外机及水模块的开闭,实现了根据末端供热设备的供热需求控制机组的水温换热速度,提升了机组供热控制的可靠性。By controlling the opening and closing of the outdoor unit and the water module according to the relationship between the equivalent actual water outlet temperature of the balancing water tank and the set temperature of the terminal heating equipment, the water temperature heat exchange speed of the unit is controlled according to the heating demand of the terminal heating equipment, thereby improving the reliability of the unit's heating control.
本实施例提供的上述空气能热泵热水机的控制方法,通过在平衡水箱中设置温度传感器,根据温度传感器的使能状态确定平衡水箱的等效水温及等效水温检测状态,并根据温度传感器的使能状态、平衡水箱的等效水温及等效水温检测状态确定平衡水箱的等效实际出水温度,在平衡水箱的等效水温检测状态出现故障时,仍然能够计算出平衡水箱的等效实际出水温度,进而能够将平衡水箱的等效实际出水温度作为恒量末端设备供热需求的关键参数,使系统在关键温度传感器出现故障时仍然能够正常工作,保证了用户的使用需求,提升了用户体验。The control method of the above-mentioned air-source heat pump water heater provided in the present embodiment sets a temperature sensor in the balancing water tank, determines the equivalent water temperature and the equivalent water temperature detection status of the balancing water tank according to the enabled state of the temperature sensor, and determines the equivalent actual water outlet temperature of the balancing water tank according to the enabled state of the temperature sensor, the equivalent water temperature of the balancing water tank and the equivalent water temperature detection status. When the equivalent water temperature detection state of the balancing water tank fails, the equivalent actual water outlet temperature of the balancing water tank can still be calculated, and then the equivalent actual water outlet temperature of the balancing water tank can be used as the key parameter of the constant terminal equipment heating demand, so that the system can still work normally when the key temperature sensor fails, thereby ensuring the user's usage needs and improving the user experience.
在一个实施例中,上述平衡水箱的上部设置有第一温度传感器BT1,平衡水箱的下部设置有第二温度传感器BT2,本实施例提供了基于温度传感器的使能状态确定平衡水箱的等效水温及等效水温检测状态的实施方式,具体可参照如下步骤执行:In one embodiment, a first temperature sensor BT1 is provided at the upper part of the above-mentioned balancing water tank, and a second temperature sensor BT2 is provided at the lower part of the balancing water tank. This embodiment provides an implementation method for determining the equivalent water temperature and the equivalent water temperature detection state of the balancing water tank based on the enabling state of the temperature sensor, which can be specifically performed with reference to the following steps:
步骤(1):当第一温度传感器的使能状态为启用状态,且第二温度传感器的使能状态为未启用状态时,将第一温度传感器检测到的第一水温作为平衡水箱的等效水温,将第一温度传感器的当前状态作为等效水温检测状态;Step (1): when the enabling state of the first temperature sensor is the enabling state, and the enabling state of the second temperature sensor is the disabling state, the first water temperature detected by the first temperature sensor is used as the equivalent water temperature of the balancing water tank, and the current state of the first temperature sensor is used as the equivalent water temperature detection state;
上述第一温度传感器可以检测平衡水箱的上部水温,第二温度传感器可以检测平衡水箱的下部水温。上述第一温度传感器和第二温度传感器的使能状态可以由用户进行设置,即设置是否使用该温度传感器检测到的温度值进行后续控制。The first temperature sensor can detect the upper water temperature of the balancing water tank, and the second temperature sensor can detect the lower water temperature of the balancing water tank. The enabling state of the first temperature sensor and the second temperature sensor can be set by the user, that is, whether to use the temperature value detected by the temperature sensor for subsequent control.
上述平衡水箱的等效水温TWT_BT也可以称为平衡水箱的折合水温(即平衡水箱的上部与下部合并后的水温)。当第一温度传感器的使能状态为启用状态,第二温度传感器的使能状态为未启用状态时,将第一温度传感器检测到的第一水温TWT_BT1赋予平衡水箱的等效水温,即令TWT_BT=TWT_BT1,第一温度传感器的当前状态即为平衡水箱的等效水温检测状态,该当前状态包括故障状态(包括开路和短路)和正常状态。The equivalent water temperature TWT_BT of the above-mentioned balancing water tank can also be called the reduced water temperature of the balancing water tank (i.e., the water temperature after the upper and lower parts of the balancing water tank are combined). When the enabling state of the first temperature sensor is enabled and the enabling state of the second temperature sensor is disabled, the first water temperature TWT_BT1 detected by the first temperature sensor is assigned to the equivalent water temperature of the balancing water tank, that is, TWT_BT=TWT_BT1. The current state of the first temperature sensor is the equivalent water temperature detection state of the balancing water tank, which includes a fault state (including an open circuit and a short circuit) and a normal state.
步骤(2):当第一温度传感器的使能状态为未启用状态,且第二温度传感器的使能状态为启用状态时,将第二温度传感器检测到的第二水温作为平衡水箱的等效水温,将第二温度传感器的当前状态作为水温检测传感器的当前状态;Step (2): when the enabling state of the first temperature sensor is the disabled state and the enabling state of the second temperature sensor is the enabled state, the second water temperature detected by the second temperature sensor is used as the equivalent water temperature of the balancing water tank, and the current state of the second temperature sensor is used as the current state of the water temperature detection sensor;
当第一温度传感器的使能状态为未启用状态,第二温度传感器的使能状态为启用状态时,由于第一温度传感器为未启用状态,将第二温度传感器检测到的第二水温TWT_BT2赋予平衡水箱的等效水温,即令TWT_BT=TWT_BT2,第二温度传感器的当前状态即为平衡水箱的等效水温检测状态。When the enable state of the first temperature sensor is not enabled and the enable state of the second temperature sensor is enabled, since the first temperature sensor is not enabled, the second water temperature TWT_BT2 detected by the second temperature sensor is assigned the equivalent water temperature of the balancing water tank, that is, TWT_BT=TWT_BT2, and the current state of the second temperature sensor is the equivalent water temperature detection state of the balancing water tank.
在一种实施方式中,当第一温度传感器的使能状态为未启用状态,第二温度传感器的使能状态为未启用状态时,令TWT_BT=TWT_BT1,将第一温度传感器的当前状态作为平衡水箱的等效水温检测状态。由于第一温度传感器和第二温度传感器的使能状态均为未启用状态,此处得到的平衡水箱的等效水温后续并未使用。In one embodiment, when the enabling state of the first temperature sensor is not enabled and the enabling state of the second temperature sensor is not enabled, let TWT_BT=TWT_BT1, and use the current state of the first temperature sensor as the equivalent water temperature detection state of the balancing water tank. Since the enabling states of the first temperature sensor and the second temperature sensor are both not enabled, the equivalent water temperature of the balancing water tank obtained here is not used later.
步骤(3):当第一温度传感器和第二温度传感器的使能状态均为启用状态时,获取第一温度传感器和第二温度传感器的当前状态,基于第一温度传感器和第二温度传感器的当前状态确定平衡水箱的等效水温及等效水温检测状态。Step (3): When the enabling states of the first temperature sensor and the second temperature sensor are both enabled, obtain the current states of the first temperature sensor and the second temperature sensor, and determine the equivalent water temperature and equivalent water temperature detection state of the balancing water tank based on the current states of the first temperature sensor and the second temperature sensor.
当第一温度传感器和第二温度传感器均为启用状态时,需要根据第一温度传感器和第二温度传感器的故障状态确定平衡水箱的等效水温及等效水温检测状态。通过根据温度传感器的使能状态确定平衡水箱的等效温度,实现了在平衡水箱中灵活配置温度传感器,从而快速准确检测平衡水箱的等效温度,提升了平衡水箱的等效温度检测的便捷性和灵活性。When the first temperature sensor and the second temperature sensor are both in the enabled state, the equivalent water temperature and the equivalent water temperature detection state of the balancing water tank need to be determined according to the fault state of the first temperature sensor and the second temperature sensor. By determining the equivalent temperature of the balancing water tank according to the enabled state of the temperature sensor, the temperature sensor can be flexibly configured in the balancing water tank, so as to quickly and accurately detect the equivalent temperature of the balancing water tank, thereby improving the convenience and flexibility of the equivalent temperature detection of the balancing water tank.

通过判断第一温度传感器和第二温度传感器是否处于故障状态,并在温度传感器出现故障时选择最能符合平衡水箱的温度检测值作为平衡水箱的等效水温,在平衡水箱的关键温度传感器出现故障时仍然能够估计平衡水箱的等效温度,从而使机组仍然能够正常工作,最大限度保证用户的应急使用需求,减少因温度传感器维修不及时造成用户使用困扰。By judging whether the first temperature sensor and the second temperature sensor are in a faulty state, and selecting the temperature detection value that best matches the balancing water tank as the equivalent water temperature of the balancing water tank when the temperature sensor fails, the equivalent temperature of the balancing water tank can still be estimated when the key temperature sensor of the balancing water tank fails, so that the unit can still work normally, maximizing the user's emergency use needs and reducing user use troubles caused by untimely maintenance of temperature sensors.
在一个实施例中,本实施例提供了基于温度传感器的使能状态、平衡水箱的等效水温及等效水温检测状态确定平衡水箱的等效实际出水温度的实施方式,具体可参照如下步骤执行:In one embodiment, this embodiment provides an implementation method for determining the equivalent actual outlet water temperature of the balancing water tank based on the enabling state of the temperature sensor, the equivalent water temperature of the balancing water tank, and the equivalent water temperature detection state. Specifically, the implementation can refer to the following steps:
步骤1):当第一温度传感器和第二温度传感器的使能状态均为未启用状态时,将水模块的出水水温传感器检测到的出水水温作为等效实际出水温度;Step 1): when the enabling states of the first temperature sensor and the second temperature sensor are both in the disabled state, the outlet water temperature detected by the outlet water temperature sensor of the water module is used as the equivalent actual outlet water temperature;
若第一温度传感器和第二温度传感器均未启用,则不使用第一温度传感器和第二温度传感器检测到的水温。水模块的出水口处设置有出水水温传感器,由于水模块的热水出水口连接至平衡水箱的进水口,水模块的出水温度与平衡水箱的温度相近,可以令平衡水箱的等效实际出水温度等于水模块的出水水温传感器检测到的出水水温。If both the first temperature sensor and the second temperature sensor are not enabled, the water temperature detected by the first temperature sensor and the second temperature sensor is not used. An outlet water temperature sensor is provided at the water outlet of the water module. Since the hot water outlet of the water module is connected to the water inlet of the balancing water tank, the outlet water temperature of the water module is close to the temperature of the balancing water tank, so the equivalent actual outlet water temperature of the balancing water tank can be made equal to the outlet water temperature detected by the outlet water temperature sensor of the water module.
步骤2):当第一温度传感器或第二温度传感器的使能状态为启用状态时,判断是否进入冬季防冻模式,如果是,判断平衡水箱的等效水温检测状态是否为故障状态;Step 2): When the enabling state of the first temperature sensor or the second temperature sensor is enabled, determine whether to enter the winter antifreeze mode, and if so, determine whether the equivalent water temperature detection state of the balancing water tank is a fault state;
若第一温度传感器或第二温度传感器均为启用状态,判断是否进入冬季防冻模式,当机组关机且室外环境温度低于预设温度时,存在管道冻结风险,确定进入冬季防冻模式。If the first temperature sensor or the second temperature sensor is enabled, determine whether to enter the winter antifreeze mode. When the unit is shut down and the outdoor ambient temperature is lower than the preset temperature, there is a risk of pipe freezing, and it is determined to enter the winter antifreeze mode.
当平衡水箱的等效水温检测状态为故障状态,且回水水温传感器的当前状态为故障状态时,将水模块的出水水温传感器检测到的出水水温作为等效实际出水温度;When the equivalent water temperature detection state of the balancing water tank is a fault state, and the current state of the return water temperature sensor is a fault state, the outlet water temperature detected by the outlet water temperature sensor of the water module is used as the equivalent actual outlet water temperature;
当平衡水箱的等效水温检测状态为故障状态,且回水水温传感器的当前状态为正常状态时,将水模块的回水水温传感器检测到的回水水温作为等效实际出水温度;When the equivalent water temperature detection state of the balancing water tank is a fault state, and the current state of the return water temperature sensor is a normal state, the return water temperature detected by the return water temperature sensor of the water module is used as the equivalent actual outlet water temperature;
当平衡水箱的等效水温检测状态为正常状态时,将平衡水箱的等效水温作为等效实际出水温度。When the equivalent water temperature detection state of the balancing water tank is normal, the equivalent water temperature of the balancing water tank is used as the equivalent actual water outlet temperature.
通过根据平衡水箱的等效水温检测状态及回水水温传感器的当前状态确定平衡水箱的等效实际出水温度,以基于正常检测状态的温度传感器检测得到的估计平衡水箱的等效实际出水温度,提升了平衡水箱的等效实际出水温度的检测准确性,从而可以提升末端供热设备的供热需求分配的可靠性。By determining the equivalent actual water outlet temperature of the balancing water tank based on the equivalent water temperature detection status of the balancing water tank and the current status of the return water temperature sensor, and estimating the equivalent actual water outlet temperature of the balancing water tank based on the temperature sensor detection in the normal detection state, the detection accuracy of the equivalent actual water outlet temperature of the balancing water tank is improved, thereby improving the reliability of the heating demand distribution of the terminal heating equipment.
步骤3):当未进入冬季防冻模式时,若平衡水箱的等效水温检测状态为故障状态,将水模块的回水水温传感器检测到的回水水温作为等效实际出水温度;若平衡水箱的等效水温检测状态为正常状态,将平衡水箱的等效水温作为等效实际出水温度。Step 3): When the winter antifreeze mode is not entered, if the equivalent water temperature detection status of the balancing water tank is a fault state, the return water temperature detected by the return water temperature sensor of the water module is used as the equivalent actual water outlet temperature; if the equivalent water temperature detection status of the balancing water tank is normal, the equivalent water temperature of the balancing water tank is used as the equivalent actual water outlet temperature.
当机组开机或关机,且室外环境温度高于预设温度时,不存在管道冻结风险,确定未进入冬季防冻模式。根据平衡水箱的等效水温检测状态确定最接近平衡水箱整体水温的等效水温,提升了平衡水箱的等效实际出水温度的检测准确性。When the unit is turned on or off, and the outdoor ambient temperature is higher than the preset temperature, there is no risk of pipe freezing, and it is determined that the winter antifreeze mode has not been entered. The equivalent water temperature closest to the overall water temperature of the balancing water tank is determined based on the equivalent water temperature detection status of the balancing water tank, which improves the detection accuracy of the equivalent actual water outlet temperature of the balancing water tank.
考虑到机组中水的惯性较大,在水温采集过程中,需要启动循环水泵运行,以使机组中的水充分循环,确保不存在死水或各末端区域存水未充分混合的情况,以提升温度传感器检测水温的精确度。Considering the large inertia of water in the unit, during the water temperature collection process, it is necessary to start the circulating water pump to allow the water in the unit to circulate fully, to ensure that there is no dead water or that the water in each terminal area is not fully mixed, so as to improve the accuracy of the temperature sensor in detecting the water temperature.
在一个实施例中,本实施例提供的方法还包括:In one embodiment, the method provided in this embodiment further includes:
当仅控制地暖开启,且地暖进水水温传感器的使能状态为启用状态时,开启地暖水泵,获取地暖进水水温传感器检测到的地暖进水水温;基于地暖进水水温及地暖设定温度切换控制阀门的运行模式;其中,控制阀门的运行模式包括混水模式和加热模式。When only the floor heating is controlled to be turned on, and the enabling state of the floor heating inlet water temperature sensor is enabled, the floor heating water pump is turned on to obtain the floor heating inlet water temperature detected by the floor heating inlet water temperature sensor; the operating mode of the control valve is switched based on the floor heating inlet water temperature and the floor heating set temperature; wherein, the operating modes of the control valve include mixing mode and heating mode.
在对末端供热设备进行开闭控制时,若仅开启地暖模式,则开启地暖水泵,并根据地暖进水水温及地暖设定温度控制地暖管道入口的控制阀门,以使地暖切换至对应的模式运行。通过在地暖模式开启时,根据地暖进水水温及地暖设定温度切换控制阀门的运行模式,以调节进入地暖的水温,确保地暖水温满足用户的供热需求,提升了用户体验。When the terminal heating equipment is turned on and off, if only the floor heating mode is turned on, the floor heating water pump is turned on, and the control valve at the entrance of the floor heating pipe is controlled according to the floor heating inlet water temperature and the floor heating set temperature, so that the floor heating is switched to the corresponding mode. When the floor heating mode is turned on, the operation mode of the control valve is switched according to the floor heating inlet water temperature and the floor heating set temperature to adjust the water temperature entering the floor heating, ensure that the floor heating water temperature meets the user's heating needs, and improve the user experience.
在一种实施方式中,当关闭地暖模式时,或者,当地暖模式开启且地暖进水水温传感器的使能状态为未启用状态时,关闭地暖管道入口的控制阀门。In one embodiment, when the floor heating mode is turned off, or when the floor heating mode is turned on and the enabling state of the floor heating inlet water temperature sensor is not enabled, the control valve at the inlet of the floor heating pipe is closed.
在一个实施例中,本实施例提供了基于地暖进水水温及地暖设定温度切换控制阀门的运行模式的具体实施方式:In one embodiment, this embodiment provides a specific implementation method for switching the operation mode of the control valve based on the floor heating inlet water temperature and the floor heating set temperature:
当地暖进水水温大于第一预设温度时,控制控制阀门切换至混水模式,以使回水管道中的低温水进入进水管道中;其中,第一预设温度为地暖设定温度与地暖开机回差温度(取值范围可以是1~3度)之和;When the inlet water temperature of the floor heating is greater than the first preset temperature, the control valve is switched to the water mixing mode to allow the low-temperature water in the return pipe to enter the inlet pipe; wherein the first preset temperature is the sum of the floor heating set temperature and the floor heating startup return temperature (the value range can be 1 to 3 degrees);
当地暖进水水温大于等于第二预设温度小于等于第一预设温度时,控制控制阀门在混水模式和加热模式之间周期性区切换;其中,第二预设温度为地暖设定温度与地暖停机回差温度(取值范围可以是1~3度)之和;When the floor heating inlet water temperature is greater than or equal to the second preset temperature and less than or equal to the first preset temperature, the control valve is controlled to periodically switch between the mixing mode and the heating mode; wherein the second preset temperature is the sum of the floor heating set temperature and the floor heating shutdown return temperature (the value range can be 1 to 3 degrees);
当地暖进水水温小于第二预设温度时,控制控制阀门切换至加热模式,以使进水管道中的热水进入地暖的管道中。When the floor heating inlet water temperature is lower than the second preset temperature, the control valve is controlled to switch to the heating mode so that the hot water in the water inlet pipe enters the floor heating pipe.
当地暖进水水温大于第一预设温度时,即地暖进水水温较高,需要降低地暖进水水温,参见如图3所示的地暖混水模式下的水循环示意图,进入地暖的水会与回水管道中的水进行循环,由于回水管道中的水在地暖管道中散热后温度降低,通过将回水管道中的水混入地暖进水管道中,可以降低地暖进水水温,使地暖进水水温接近地暖设定温度。When the floor heating inlet water temperature is greater than the first preset temperature, that is, the floor heating inlet water temperature is high, it is necessary to lower the floor heating inlet water temperature. Referring to the water circulation diagram under the floor heating mixed water mode as shown in FIG3 , the water entering the floor heating will circulate with the water in the return water pipe. Since the water in the return water pipe cools down in the floor heating pipe, the temperature of the floor heating inlet water can be lowered by mixing the water in the return water pipe into the floor heating inlet water pipe, so that the floor heating inlet water temperature is close to the floor heating set temperature.
当地暖进水水温大于等于第二预设温度小于等于第一预设温度时,地暖进水水温适中,为了保持该地暖进水水温,控制地暖的控制阀门切换至混水模式运行第一预设时长(取值范围可以是1~3min,优选3min),再控制地暖的控制阀门切换至加热模式运行第二预设时长(取值范围可以是1~3min,优选3min),并依次循环,上述第一预设时长与第二预设时长可以相等或不等。When the floor heating inlet water temperature is greater than or equal to the second preset temperature and less than or equal to the first preset temperature, the floor heating inlet water temperature is moderate. In order to maintain the floor heating inlet water temperature, the floor heating control valve is controlled to switch to the mixing water mode and run for the first preset time (the value range can be 1 to 3 minutes, preferably 3 minutes), and then the floor heating control valve is controlled to switch to the heating mode and run for the second preset time (the value range can be 1 to 3 minutes, preferably 3 minutes), and the cycle is repeated in sequence. The above-mentioned first preset time and the second preset time can be equal or different.
当地暖进水水温小于第二预设温度时,即地暖进水水温较低,需要升高地暖进水水温,参见如图4所示的地暖加热模式下的水循环示意图,将加热后的水输入地暖管道中,可以提升地暖进水水温,使地暖进水水温接近地暖设定温度。When the floor heating inlet water temperature is lower than the second preset temperature, that is, the floor heating inlet water temperature is low, it is necessary to increase the floor heating inlet water temperature. Referring to the water circulation diagram under the floor heating heating mode as shown in FIG4 , the heated water is input into the floor heating pipe to increase the floor heating inlet water temperature so that the floor heating inlet water temperature is close to the floor heating set temperature.
通过根据地暖进水水温与地暖设定温度的关系切换控制阀门,以提升或降低进入地暖的进水水温,使地暖进水水温保持在地暖设定温度附近,从而满足用户的地暖供热需求,提升了用户的舒适性。By switching the control valve according to the relationship between the floor heating inlet water temperature and the floor heating set temperature, the inlet water temperature entering the floor heating can be increased or decreased, so that the floor heating inlet water temperature is maintained near the floor heating set temperature, thereby meeting the user's floor heating heating needs and improving the user's comfort.
本实施例提供的上述空气能热泵热水机的控制方法,通过水温传感器灵活配置,提高了用户使用便利及舒适性需求;通过温度传感器采集算法,重要位置水温传感器故障后,机组仍能正常工作,最大限度保证用户应急使用需求,减少因维修不及时造成用户使用困扰。The control method of the air-source heat pump water heater provided in this embodiment improves the user's convenience and comfort requirements through the flexible configuration of water temperature sensors; through the temperature sensor acquisition algorithm, after the water temperature sensor at an important position fails, the unit can still work normally, thereby maximizing the user's emergency use needs and reducing the user's use troubles caused by untimely maintenance.

When the equivalent water temperature detection state of the balancing water tank fails, the equivalent actual water outlet temperature of the balancing water tank can still be calculated, and then the equivalent actual water outlet temperature of the balancing water tank can be used as the key parameter of the constant terminal device heating demand, so that the system can still work normally when the key temperature sensor fails, thereby ensuring the user's usage needs and improving the user experience.
