本公开一些实施例提供了一种制冷设备的控制方法。图2是根据本公开实施例的一种制冷设备的控制方法流程图。如图2所示，该流程包括如下步骤。
在步骤S202，控制制冷设备的热负荷状态。
在本公开一些实施例中，热负荷状态为温度状态。例如，通过控制较低的目标蒸发温度和较高的室内机风机转速可以控制热负荷状态，实现环境温度的控制。环境温度为制冷设备所处的环境的温度。
在步骤S204，在热负荷状态满足热负荷需求时，控制制冷设备的湿负荷状态。
在本公开一些实施例中，湿负荷状态为湿度状态。湿负荷是指空调所处室内(或环境)的湿源向室内的散湿量，也就是为维持室内含湿量恒定需从室内(或环境)除去的湿量。通过控制较低的目标蒸发温度和较低的室内机风机转速，实现环境湿度的控制。人体体感的温度和舒适度与室内的温度和湿度同时相关。
在步骤S206，在湿负荷状态满足湿负荷需求时，通过控制制冷设备的目标蒸发温度和制冷设备的风机的转速中的至少一个控制环境温度。
通过上述步骤，控制制冷设备的热负荷状态，在所述热负荷状态满足热负荷需求时，然后控制所述制冷设备的湿负荷状态，最后在所述湿负荷状态满足湿负荷需求时，通过控制制冷设备的目标蒸发温度和制冷设备的风机的转速中的至少一个控制环境温度。通过优先快速满足热负荷需求，再快速满足湿负荷需求，最后维持等于或大于露点温度的蒸发温度，调整室内机风机转速满足环境温度需求的控制，制冷设备可以适用不同的热负荷和湿度的场景。解决了制冷设备在制冷时不能适应不同地区不同气候特性的问题，提高了送风质量，节省了能源，提高了舒适性。
在本公开实施例的一些实施方式中，控制制冷设备的热负荷状态包括：控制制冷设备以第一目标蒸发温度运行，或，控制制冷设备的制冷设备风机以第一转速运行，或，控制制冷设备以第一目标蒸发温度运行且控制制冷设备的制冷设备风机以第一转速运行，直到当前热负荷状态满足热负荷需求。如此可以快速降温，优先快速满足热负荷需求。
在本公开实施例的一些实施方式中，控制制冷设备的湿负荷状态包括步骤S11-步 骤S13。
在步骤S11，检测环境湿度。
在步骤S12，比较环境湿度和湿负荷需求值。
在步骤S13，在环境湿度大于湿负荷需求值时，控制制冷设备以第二目标蒸发温度运行，或，控制制冷设备的制冷设备风机以第二转速运行，或，控制制冷设备以第二目标蒸发温度运行且控制制冷设备的制冷设备风机以第二转速运行，直到当前湿负荷状态满足湿负荷需求；在环境湿度小于或等于湿负荷需求值时，确定当前湿负荷状态满足湿负荷需求。
在本公开一些实施例中，第二目标蒸发温度大于第一目标蒸发温度，第二转速小于第一转速。
在本公开一些实施例中，在热负荷状态满足热负荷需求时，然后再考虑湿负荷。若湿负荷较大，则自动调整制冷设备以低于露点的低蒸发温度运行，并自动调整室内机风机以较低的转速运行，以快速除湿。
在本公开一些实施例中，通过控制目标蒸发温度和制冷设备的风机的转速控制环境温度包括：调整所述制冷设备的目标蒸发温度，控制所述制冷设备以第三目标蒸发温度运行；检测室内的实时温度差，即室内温度与用户设定温度的差值；在实时温度差大于A(大于0)时，增大制冷设备风机的转速；在实时温度差小于-A，减小制冷设备风机的转速；在实时温度差小于或等于A且大于或等于-A，保持制冷设备风机的转速不变，其中，A为判断是否满足热负荷需求的预设值。在一些实施例中，第三目标蒸发温度大于第二目标蒸发温度。
在一些实施例中，所述第三目标蒸发温度大于或等于所述制冷设备根据当前室内温湿度计算得到的露点温度。
图3是根据本公开实施例的制冷设备的控制流程图。制冷设备的运行环境为室内。T，为检测的室内温度值；Ts，为检测的室内湿度值；T0，为用户设定温度值；△T，为室内热负荷判定值，即T-T0的差值；A，为室内热负荷需求值，即用来判断室内热负荷判定值△T是否在用户设定温度值的合适范围内；B，为室内湿负荷需求值，即用来判断室内是否需要除湿；Ta，为目标低蒸发温度值，主要适用于快速降温；Tb，为目标蒸发温度值，主要适用于除湿；TL，为通过室内环境温度和湿度计算出来的室内露点温度；K，为制冷设备(例如空调系统)的制冷效果修正值；Tc，为和室内露点温度相近的目标蒸发温度值，主要用于降温，不除湿Ta＜Tb＜Tc；Ra，为室内机 风机较高转速；Rb，为室内机风机较低转速。控制流程包括蒸发温度和室内机风机转速自动控制逻辑流程，包括三个阶段：机组制冷启动时，快速降温阶段；热负荷满足需求后，快速除湿阶段；最后热湿负荷都基本满足后，只降温不除湿阶段。控制逻辑流程如下。
在S31、机组制冷启动运行后，首先检测室内温度T和用户设定温度T0，然后以默认的目标低蒸发温度Ta和室内机风机高转速Ra运行，快速降温。
在S32、当检测计算热负荷判定值△T，即室内温度T与用户设定温度T0的差值，小于等于热负荷需求值A时，即判断室内的热负荷需求已满足。
在S33、然后检测室内湿度Ts，并与湿负荷需求值B对比。若Ts＞B，则说明系统需要除湿，以目标蒸发温度Tb和室内机风机低转速Rb运行，快速除湿。
在S34、当检测室内湿度Ts≤B时，说明室内已没有湿负荷需求，不需要再除湿，系统修订目标蒸发温度为Tc。Tc为此时根据室内环境温湿度计算的露点温度TL与制冷效果修正值K之和。
在S35、最后，通过自动调整室内机风机转速来满足室内热负荷需求。当热负荷判定值△T＞A时，室内机风机转速增大；当△T＜-A时，室内机风机转速减小；当-A≤△T≤A时，室内机风机转速保持不变。
本公开实施例提出了一种蒸发温度和室内机风机转速自动调整的控制方法。在制冷运行时，根据系统实际的热湿负荷来判断室内侧的降温程度、及是否需要除湿，来进行自动调整目标蒸发温度和室内机转速，使系统能兼顾高热负荷高湿度、高热负荷低湿度、低热负荷高湿度和低热负荷低湿度等多种场景，同时满足热湿负荷的需求，提高舒适性和节能性。
本公开一些实施例的方案可以解决由于空调采用恒定蒸发温度控制，不考虑湿负荷导致的过度除湿、能源浪费，及室内湿度高、送风品质差的问题。另外，本公开一些实施例的方案可以解决空调系统只控制恒定蒸发温度，热负荷和湿负荷不能兼顾，舒适性差的问题。在一些实施例中，可使空调系统在高热负荷高湿度、高热负荷低湿度、低热负荷高湿度和低热负荷低湿度等多种场景下以最佳的蒸发温度和室内机风机转速运行。在一些实施例中，可使空调系统在刚开机运行时，以较低的蒸发温度和较高的室内机风机转速运行，快速降温，优先快速满足热负荷需求；然后再考虑湿负荷，在湿负荷较大时，自动调整空调系统以低于露点的低蒸发温度和室内机风机较低的室内机风机转速运行，快速除湿；最后热湿负荷都基本满足需求后，空调系统以高于露 点的蒸发温度运行，只降温不除湿，且此时室内机风机转速随热负荷自动调整，若热负荷过高，调高室内机风机转速，以满足需求。同时满足热湿负荷需求，提高空调系统的舒适性和节能性。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，在一些实施例中，本公开的技术方案本质上或者说对发明人知晓的技术做出贡献的部分以计算机软件产品的形式体现出来。该计算机软件产品存储在存储介质(如ROM/RAM、磁碟、光盘)中，存储介质包括若干指令用以使得终端设备(例如手机，计算机，服务器，或者网络设备等)执行本公开各个实施例所述的方法。
