Description

空调器及其送风控制方法 技术领域
本发明属于空调器技术领域,具体涉及一种空调器及其送风控制方法。
背景技术
随着人们生活水平的不断提高,人们对生活环境也提出了越来越高的要求。为了维持舒适的环境温度,空调器已经成为人们生活中必不可少的一种设备。近年来,随着空调技术日益成熟,用户对空调器的综合性能也提出了越来越高的要求。以空调器的送风方式为例,为了有效保证空调器的送风温度能够贴合用户的换热需求,现有很多空调器都会在运行一段时间后再开启室内风机,目的就是在室内盘管的温度上升或下降至符合用户的换热需求时再开始送风,以便室内机送出的风能够让用户感到舒适;但是,这种送风方式其实并不能保证室内机送出的风始终都能够让用户感到舒适。
具体而言,现有空调器都是在室内盘管温度达到某个温度时才控制室内风机运转,并且室内风机的转速通常都是由用户设定的转速决定的。以空调器运行制热工况时为例,由于室内风机的转速也可能会影响室内机的送风温度,特别是在室内空间很大时,室内温度往往很难在短时间内快速上升;在室内温度较低的情况下,室内机出风口的温度在很长一段时间内也会处于较低状态,而用户此时又很容易因为想要室内温度快速上升而将室内风机的转速设定为最大转速,但是,其实在室内温度较低的情况下,即使室内盘管温度已经上升至某个温度,如果此时室内风机的转速过大还是可能会吹出令用户感觉到冷的风,从而严重影响用户体验。
相应地,本领域需要一种新的空调器及其送风控制方法来解决上述问题。

S1:获取室内机的当前回风温度;
S2:根据室内机的当前回风温度,选择性地使室内风机以目标转速运行。
进一步地,在步骤S1中,所述控制器能够通过所述回风温度传感器获取所述室内机的当前回风温度;可以理解的是,特别是当房间足够大时,所述室内机附近的温度往往可能和房间其他地方的温度有所差异,因而所述室内机的回风温度也可以被看作所述室内机附近的温度,从而有效避免直接采用室内温度作为参数时难以准备判断所述室内机附近的温度情况的问题,即本发明的送风控制方法通过获取所述室内机的当前回风温度作为基础参数来有效提高判断的准确性。需要说明的是,本发明不对所述控制器获取当前回风温度的方式作任何限制,技术人员也可以通过在所述室内机的回风口附近设置温度传感器来获取温度数据以作为所述室内机的当前出风温度。
进一步地,在步骤S2中,所述控制器能够根据所述室内机的当前回风温度选择性地使所述室内风机以目标转速运行;需要说明的 是,所述控制器可以通过控制所述室内风机的驱动电机的转速来控制所述室内风机的转速,而所述目标转速通常是用户设定的转速,这个转速是通过用户设定的风速确定的。此外,还需要说明的是,本发明不对其具体控制方式作任何限制,所述控制器既可以通过判断所述当前回风温度所处的温度范围来选择性地使所述室内风机以目标转速运行,也可以通过判断所述当前回风温度是否满足预设函数来选择性地使所述室内风机以目标转速运行,技术人员可以根据实际使用需求自行设定其具体控制方式,只要该方式中采用所述当前回风温度作为基础参数来选择性地使所述室内风机以目标转速运行就属于本发明的保护范围。
下面参阅图2,该图是本发明的送风控制方法的优选实施例的步骤流程图。如图2所示,以所述空调器运行制热工况时为例,并且基于上述优选实施例中所述的空调器,所述送风控制方法的优选实施例具体包括下列步骤:
S101:获取室内机的当前回风温度;
S102:判断当前回风温度是否小于预设温度;如果是,则执行步骤S104;如果否,则执行步骤S103;
S103:使室内风机以目标转速运行;
S104:获取室内机的当前盘管温度;
S105:根据当前盘管温度、当前回风温度以及预设温度,确定室内风机的转速;
S106:判断确定出的转速是否小于目标转速;如果是,则执行步骤S107;如果否,则执行步骤S108;
S107:使室内风机以确定出的转速运行;
S108:使室内风机的转速等于目标转速,再使室内风机以该转速运行。
进一步地,在步骤S101中,所述控制器能够通过所述回风温度传感器获取所述室内机的当前回风温度;可以理解的是,特别是当房间足够大时,所述室内机附近的温度往往可能和房间其他地方的温度有所差异,因而所述室内机的回风温度也可以被看作所述室内机附近的温度,从而有效避免直接采用室内温度作为参数时难以准备判断所述室内机附近的温度情况的问题,即本发明的送风控制方法通过获取所述室 内机的当前回风温度作为基础参数来有效提高判断的准确性。需要说明的是,本发明不对所述控制器获取当前回风温度的方式作任何限制,技术人员也可以通过在所述室内机的回风口附近设置温度传感器来获取温度数据以作为所述室内机的当前出风温度。
进一步地,在步骤S102中,所述控制器判断所述当前回风温度是否小于所述预设温度,以便判断所述室内机是否有可能因为室内风机风速的改变而吹出冷风。需要说明的是,本发明不对所述预设温度具体取值方式作任何限制,例如,所述预设温度可以是一个设定的常数值,如26℃;当然,优选地,所述预设温度根据用户设定的目标室内温度来确定,以便本发明的送风控制方法能够更好地贴合不同用户的换热需求,换言之,技术人员可以根据实际使用需求自行设定所述预设温度的具体数值。
基于步骤S102中的判断结果,如果所述控制器判断出所述当前回风温度不小于所述预设温度,则说明无论用户将所述室内风机的转速设定为何值,所述室内机都不会吹出冷风;在此情形下,执行步骤S103,即所述控制器直接控制所述室内风机以所述目标转速运行,以便有效满足用户需求的送风量。如果所述控制器判断出所述当前回风温度小于所述预设温度,则说明所述室内机是否会吹出冷风会受到所述室内风机的转速的影响;在此情形下,执行步骤S104,即所述控制器通过所述盘管温度传感器获取所述室内盘管的当前温度。需要说明的是,本发明不对所述控制器获取当前盘管温度的方式作任何限制,技术人员可以根据实际使用需求自行设定。
更进一步地,在所述控制器获取到所述室内盘管的当前盘管温度的基础上,执行步骤S105,即所述控制器能够根据所述当前盘管温度、所述当前回风温度和所述预设温度确定所述室内风机的转速。需要说明的是,本发明不对所述室内风机的转速的具体确定方式作任何限制,技术人员可以根据实际使用需求自行设定,只要转速确定的过程中使用到所述当前盘管温度、所述当前回风温度和所述预设温度参与转速确定过程即可;优选地,所述控制器能够通过下列等式确定所述室内风机的转速N:
Figure PCTCN2020095079-appb-000002
其中,Tp i为所述室内机的当前盘管温度,Ta i为所述室内机的当前回风温度,Tp 0为目标盘管温度,T 0为所述预设温度,k1为第一修正系数,N s为所述目标转速,N 0为所述室内风机的最低转速,k2为第二修正系数,Tp i-1为所述室内机的上一时刻盘管温度,ΔN为所述室内风机的转速的单次调整量。
需要说明的是,上式中的Tp i就是步骤S104中获取到的当前盘管温度;上式中的Ta i就是步骤S101中获取到的当前回风温度;上式中的Tp 0为目标盘管温度,技术人员需要根据空调器的不同情况自行设定所述目标盘管温度,优选为50℃;上式中的T 0就是步骤S102中所采用的预设温度;上式中的N s就是步骤S103中所采用的目标转速;上式中的N 0为所述室内风机的最低转速,每个风机都有各自的转速范围,所述最低转速就是所述室内风机的转速范围内的最小值;上式中的第一修正系数k1和第二修正系数k2均需要技术人员根据空调器的具体结构自行通过多次拟合实验来确定;上式中的Tp i-1为所述室内机的上一时刻盘管温度,所述控制器每隔一段时间就会测量一次盘管温度,当然,两次测量的时间间隔都是由技术人员自行设定的,上式通过计算Tp i-Tp i-1就可以得出室内盘管温度在一个时间间隔内的改变量;上式中的ΔN为所述室内风机的转速的单次调整量,技术人员可以根据所述室内风机的驱动电机的实际情况自行设定所述单次调整量。
本领域技术人员能够理解的是,本发明的送风控制方法能够通过上式计算出所述室内风机的最佳转速,以便在有效保证所述室内机能够始终吹出热风的情况下,还能够尽量保证所述室内风机能够以较大的转速运行,进而在有效保证用户体验的基础上还能够最大程度地保证所述室内机的换热速率。
更进一步地,由于部分用户就是偏好于使用较小风速进行换热,因此,在通过上式计算出所述室内风机的最佳转速以后,执行步骤S106,即所述控制器能够判断通过上式确定出的转速是否小于所述目标转速。基于步骤S106中的判断结果,如果所述控制器判断出通过上式确定出的转速小于所述目标转速,则说明直接使所述室内风机以用户设定的转速运行也能保证所述室内机吹出的风为较热的风,在此情形下,执行步骤S107,即所述控制器直接控制所述室内风机以上式确定出的转速 运行,以便有效保证所述室内机吹出的风始终为热风。如果所述控制器判断出通过上式确定出的转速不小于所述目标转速,则说明用户设定的风速就较小,在此情形下,为了充分贴合用户的吹风偏好,执行步骤S108,即所述控制器能够令所述室内风机的转速等于所述目标转速,然后再控制所述室内风机以所述室内风机的转速运行,也就是控制所述室内风机以所述目标转速运行。当然,这也不是限制性的,所述控制器也可以不将通过上式确定出的转速与目标转速进行比较,即所述控制器始终控制所述室内风机以确定出的转速运行。
最后需要说明的是,上述实施例均是本发明的优选实施方案,并不作为对本发明保护范围的限制。本领域技术人员在实际使用本发明时,可以根据需要适当添加或删减一部分步骤,或者调换不同步骤之间的顺序。这种改变并没有超出本发明的基本原理,属于本发明的保护范围。
至此,已经结合附图描述了本发明的优选实施方案,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。
