Description

空调器及其控制方法 技术领域
本发明涉及空气调节技术领域,具体涉及一种空调器及其控制方法。
背景技术
在空调在低温地区或者风雪较大的地区运行时,室外机的冷凝器外表面所凝结水流会滴落到室外机底盘上,从而导致空调器的室外机底盘出现结冰问题,使得底盘无法正常排水。特别是室外机换热器除霜后,霜融化形成的水滴残留在底盘上,也会加剧底盘的结冰状况。
现有技术中关于底盘的除霜方式主要是在底盘设置有电加热丝,根据检测到的环境温度来控制电热丝的启闭,从而实现底盘除霜。具体地,当检测到的室外环境温度值低于3℃时,开启电加热丝;在检测到的室外环境温度高于5℃时,关闭电加热丝。然而在很多情况下,虽然检测到的室外环境温度值低于3℃,但底盘并未结霜而此时电加热丝却依然维持开启状态,这样一来,会增加了很多不必要的电量消耗。
相应地,本领域需要一种新的空调器的室外机底盘除霜控制方案来解决上述问题。
发明内容

附图说明
下面参照附图来描述本发明的空调器及其控制方法。附图中:
图1为本发明的一种实施例中空调器的控制方法的流程示意图;
图2为本发明的一种实施例中步骤S30的流程示意图。
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。例如,尽管本申请中按照特定顺序描述了本发明的方法的各个步骤,但是这些顺序并不是限制性的,在不偏离本发明的基本原理的前提下,本领域技术人员可以按照不同的顺序来执行所述步骤。
需要说明的是,在本发明的描述中,术语“第一”、“第二”仅用于描述目的,而不能理解为指示或暗示相对重要性。此外,在本发明的描述中,除非另有明确的规定和限定,术语“安装”、“相连”、“连接”应做广义理解,例如,可以是固定连接,也可以是可拆卸连接,或一体地连接;可以是机械连接,也可以是电连接;可以是直接相连,也可以通过中间媒介间接相连,可以是两个元件内部的连通。对于本领域技术人员而言,可根据具体情况理解上述术语在本发明中的具体含义。
本发明的空调器包括室内机和室外机,室外机包括底盘,底盘设置有用于除霜的电加热丝和用于检测底盘温度的底盘温度传感器。室外机的回气侧设置有用于采集室内环境温度的环境温度传感器。
参照图1,图1为本发明的一种实施例中空调器的控制方法的流程示意图。如图1所示,基于空调器的上述结构,本发明的空调器的控制方法包括如下步骤:
步骤S10:在空调器处于制热工况的情形下,获取室外机所处的环境温度。
步骤S20:在环境温度满足设定条件的情形下,获取底盘温度。
步骤S30:至少根据底盘温度控制加热装置的启闭状态。
优选地,在步骤S20中,设定条件为环境温度大于等于第三阈值。经过发明人长时间的实验研究发现:对于不同机型而言,在室外机所处的环境温度小于0℃的情形下,室外机底盘一般会存在一定程度的结霜情况。然而在 环境温度处于0℃以上时,室外机底盘的结霜情况较复杂,此时仅根据环境温度对底盘结霜情况进行判定会存在较大误差,经常会出现底盘并无结霜而电加热丝却依然维持开启状态的现象,从而增加了很多不必要的电量消耗。因此本发明在底盘内侧设置有底盘温度传感器,利用底盘温度传感器采集到的底盘温度来直接判断在环境温度大于等于零度的情形下的底盘结冰情况,进而控制底盘的电加热丝的启闭状态。
基于上述发现并考虑到空调器的环境温度传感器采集的数据与真实的环境温度会存在小范围的误差,优选地,第三阈值的取值范围为0℃至1℃。
进一步地,在环境温度小于等于第三阈值的情况下,此时由于室外机底盘基本存在结霜,因此,此时在环境温度小于等于第三阈值的情况下,无需考虑底盘温度,直接使电加热丝处于开启状态。
需要说明的是,在实际应用中,设定条件的具体内容不仅限于上述这一种情况,本领域技术人员可以根据实际的应用场景对设定条件的具体内容进行灵活调整。
可以看出,本发明在原有的室外环境温度作为底盘结霜情况判定要素的基础上,针对室外环境温度在零度以上这种底盘结霜情况较为复杂的情形,进一步加入底盘温度传感器获取的底盘温度作为底盘结霜情况判定要素,由于底盘温度可以直接反映底盘的结霜情况,因此将底盘温度作为判定要素可以更为精确地判定室外环境温度在零度以上工况底盘结霜情况,从而减少了室外环境温度在零度以上工况下底盘无霜冻而电加热丝却依然控制开启的情况出现,避免电加热丝产生无用电耗。
接下来参照图2,图2为本发明的一种实施例中步骤S30的流程示意图。如图2所示,在一种优选的实施方式中,步骤S30具体包括:
步骤S310:判断底盘温度是否小于等于第一温度阈值:
若否,执行步骤S320;若是,执行步骤S330。
步骤S320:使电加热丝保持关闭状态,并返回步骤S20。
步骤S330:使电加热丝处于开启状态。
步骤S340:继续获取室外机的底盘温度。
步骤S350:判断底盘温度是否大于等于第二温度阈值:
若否,执行步骤S360;若是,执行步骤S370。
步骤S360:使电加热丝保持开启状态,并返回步骤S340。
步骤S370:使电加热丝处于关闭状态。
根据发明人长时间的实验研究发现,不同机型的空调器的室外机的底盘结霜的极限温度基本处于0℃至-1℃的范围内,也就是说,在室外机的底盘温度小于等于该极限温度的情形下,室外机的底盘均有一定程度的结霜情况。基于此,在步骤S310中,优选地,第一温度阈值的取值范围为0℃至-1℃。其中,第一温度阈值的具体取值可以根据实际情形进行选择。
根据发明人进一步的实验研究发现:不同机型的空调器的室外机的底盘无霜的极限温度基本处于0℃至1℃,也就是说,在底盘温度大于等于0℃至1℃的情形下,空调器的室外机的底盘基本处于无霜状态。基于此,在步骤S350中,第二温度阈值的取值范围0℃至1℃。其中,第二温度阈值的具体取值可以根据实际应用场景在该取值范围内进行选择。
可以看出,本发明的控制方法根据底盘温度与第一温度阈值、第二温度阈值的比较结果确定底盘结霜状态以控制电加热丝的启闭状态,从而在保证及时且高效的除霜效果的同时,还能节约能源。
进一步地,为了避免电加热丝的频繁启动,在上述优选的实施方式的基础上,本发明在上述步骤S310的判定条件中增设电加热丝由关闭到再次开启的停机时长的判定,具体地,在上述其他步骤不变的情形下,优化后的步骤S310为:
判断空调器是否同时满足以下条件:
电加热丝由关闭到再次开启的停机时长大于等于预设时间阈值且底盘温度小于等于第一温度阈值:
若否,执行步骤S320;若是,执行步骤S330。
上述设置的优点在于:通过设置预设时间阈值作为电加热丝再次开启所需的最短间隔时间,在上述步骤S310的判定条件中增设电加热丝由关闭到再次开启的停机时长是否满足预设时间阈值的判定,从而避免电加热丝频繁开启而影响电加热丝的使用寿命。
虽然上述示例是以电加热丝作为用于底盘除霜的加热设备为例介绍了本发明的控制方法,但本领域技术人员能够理解的是,本发明应不限于此。事实上,用于室外机底盘除霜的加热设备还可以为任意具有加热功能的设备,本领域技术人员可以根据实际情形对加热设备的具体形式进行设定,以便满足具体的应用需求。
综上所述,本发明通过在环境温度作为室外机底盘的结霜情况判定要素的基础上,在环境温度大于等于0℃至1℃的情形下,通过设置于室外机底盘内侧的底盘温度传感器采集的底盘温度数据来判断底盘的结霜情况并据此来控制电加热丝的启闭状态,从而实现更为直观且精准的底盘结霜情况判定和除霜控制,减少了底盘无霜冻而电加热丝却依然控制开启的情况出现,避免电加热丝产生无用电耗。
本领域技术人员能够理解的是,除上述描述的空调器各零部件外,空调器显然还包括其他零部件和结构,本实施方式中虽然没有描述,但是这些零部件应当按照现有技术中的空调器所具备的形状和特征进行理解,并且这些形状和特征不应当被看做是对本发明的限制。例如,空调器的室外机还可以包括压缩机、换热器等。
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。
