Description

本发明属于空调器技术领域，具体提供一种风冷热泵热水空调机组及其控制方法。
背景技术
现有风冷热泵冷热水机组产品中使用的水测换热器由于与水接触，不可避免的会产生水垢，从而影响换热，导致机组不能正常运行，而且由于机组使用的水源为自来水，并且各地的自来水水质各不相同，不同地区由于水垢导致不能正常运行的时间和概率均有极大差别，而且一旦出现这种情况，维修人员到现场也很难分析出是否为水垢引起的机组不能正常运行。
相应的，本领域需要一种风冷热泵热水空调机组及其控制方法来解决现有空调机组难以判断其自身产生的水垢是否引起了机组不能正常运行的问题。
发明内容
为了解决现有技术中的上述问题，本发明提供了一种风冷热泵热水空调机组的控制方法，所述空调机组包括进水口、出水口、压缩机、设置于所述出水口处的温度检测部件和设置于压缩机输入电路的电流检测部件，所述控制方法包括：

附图说明
下面参照附图来描述本发明的风冷热泵热水空调机组的控制方法。附图中：
图1为本发明的风冷热泵热水空调机组的三维图；
图2为本发明的风冷热泵热水空调机组的控制方法的流程图。
附图标记列表：
1、进水口；2、出水口。
具体实施方式
下面参照附图来描述本发明的优选实施方式。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。本领域技术人员可以根据需要对其作出调整，以便适应具体的应用场合。例如，尽管说明书附图中的步骤S600是当I≤I 0时，控制空调机组正常运行，但是，这样的话方法 就已经结束，并不能完成持续观察，若要紧密进行观察，还可以是当I≤I 0时，控制空调机组正常运行△t时间，并重新返回步骤S100，这样的话就是只要检测出机组正常后，正常运行△t时间，还可以继续进行下一次循环判断，以完成持续监测空调机组运行状况，也减少了误判的可能性。
参照图1和图2，对本发明的风冷热泵热水空调机组的控制方法的一种实施方式进行详细描述。
空调机组包括进水口1、出水口2、压缩机(在空调机组内部，图中未示出)、设置于出水口处的温度检测部件(图中未示出)和设置于压缩机输入电路的电流检测部件(图中未示出)，本发明的控制方法的一种实施方式见图1，包括：
S100、控制温度检测部件获取出水口的出水温度T；
S200、控制电路检测部件获取压缩机输入电路的电流I；
S300、获取出水口的出水温度T情况下的标准电流I 0；
S400、判断I与I 0的大小；
S500、当I＞I 0时，发出清洁水垢的提示；
S600、当I≤I 0时，控制空调机组正常运行。
需要说明的是，温度监测部件、电流检测部件等均为常规的零件或装置，由于能实现温度检测和电流检测的装置太多，例如温度计、电流表等等，不再一一列举。另外，标准电流I 0的获取也是多种多样，例如通过实际经验，在出厂时挨个检测在不同温度下的标准电流，再存储于空调机组内，以供使用时调用，或者根据经验公式进行计算，或者其它公式进行计算获得等等，不再一一列举。
首先通过温度检测部件和电流检测部件来获取出水温度T和输入电路的电流I，再获取出水口的出水温度T情况下的标准电流I 0，两者进行比较，如果I≤I 0，说明此时空调机组运行正常，无需对其进行水垢清洁，继续控制空调机组正常运行即可，如果I＞I 0，说明加热水至相同温度的情况下电流值增加，产生了异常情况，则此时判定为水垢造成了风冷热泵热水空调机组加热功能降低，此时发出清洁水垢的提示，使上门的操作人员能够知晓结果，从而进行清洁。
上述实施方式能够阐述清楚本发明的基本原理，在此基础上，本发明的控制方法还可以有一些优化和改进，例如，在另一种可 能的实施方式中，步骤S500还可以替换为“当I＞I 0+I 补偿时，提示用户清洁水垢，其中，I 补偿≥0”，由于空调器在使用过程中难免会老化，而这就有可能导致标准电流I 0也随着使用年限的增长而增加，一直依靠出厂设置的标准电流值并不能适用于某个单独的空调器，此时增加补偿值，则能够对于单个空调器进行优化补偿，从而使本发明的控制方法的判断更加准确。
另外，在上述补偿的方案中，补偿还可能跟检测波动有关系，尤其是在一些电网欠发达的地区，电流输入本来就不稳定，此时波动较大，将带来持续性的报警，使用户体验变差，因此，设置I 补偿的数值也尤为重要，发明人经过实际实验，得出一种优选地实施方式为I 补偿的数值为0.5安培。
在另一种可能的实施方式中，步骤S600还可以替换为“当I≤I 0时，控制空调机组正常运行△t时间，并重新返回步骤S100”。此种设计的优势在于，能够每隔△t时间对空调机组进行一次检测，而避免漏检的情况产生，△t的时间可以灵活设置。
在另一种可能的实施方式中，步骤S500中的发出清洁水垢的提示的方式多样，可以是“控制报警指示灯闪烁，以提示用户清洁水垢”，还可以是“控制显示面板显示需要清洁水垢的文字或图片信息，以提示用户清洁水垢”等等。
另外，为了实现自动化，本发明还提供了一种风冷热泵热水空调机组的控制方法，空调机组包括进水口、出水口、压缩机、设置于出水口处的温度检测部件和设置于压缩机输入电路的电流检测部件，空调机组还包括水垢清洁部件，此方案的空调机组的结构与前述技术方案的空调机组结构略有不同，新增了水垢清洁部件，相应地，控制方法也略有不同，区别点在于，本方案当I＞I 0时，可以控制水垢清洁部件开始清洁水垢，至于是否发出清洁水垢的提示可以任意选择。当然，水垢清洁部件本发明并未进行展开，但本领域技术人员能够根据实际结构进行灵活设计，例如通过电动刮板刮除水垢等等方式。
另外，本发明还提供了一种风冷热泵热水空调机组，该空调机组为上述技术方案中的空调机组，空调机组还包括控制器，控制器能够执行上述技术方案中的控制方法。也即如果空调机组不带有清洁水垢部件，则执行仅发出清洁水垢提示的控制方法，如果空调机组 带有清洁水垢部件，则执行带有清洁水垢部件的控制方法或不带有清洁水垢部件的控制方法均可。
需要说明的是，上述实施方式仅仅用来阐述本发明的原理，并非旨在与限制本发明的保护范围，在不偏离本发明原理的条件下，本领域技术人员能够对上述结构进行调整，以便本发明能够应用于更加具体的应用场景。
本领域技术人员可以理解，上述风冷热泵热水空调机组还包括一些其他公知结构，例如处理器、控制器、存储器等，其中，存储器包括但不限于随机存储器、闪存、只读存储器、可编程只读存储器、易失性存储器、非易失性存储器、串行存储器、并行存储器或寄存器等，处理器包括但不限于CPLD/FPGA、DSP、ARM处理器、MIPS处理器等。为了不必要地模糊本公开的实施例，这些公知的结构未在附图中示出。
上述实施例中虽然将各个步骤按照上述先后次序的方式进行了描述，但是本领域技术人员可以理解，为了实现本实施例的效果，不同的步骤之间不必按照这样的次序执行，其可以同时(并行)执行或以颠倒的次序执行，这些简单的变化都在本发明的保护范围之内。
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。
