空调器常常在室外换热器下方的接水盘设置电加热器，当温度较低时开启电加热器来 对接水盘中的水进行加热，避免接水盘中的水结冰。电加热器属于低能效器件，能效不超过1.0，耗电量较高；而空调器属于高能效产品，且目前的空调器能效要求越来越高，增加电加热器会拉低整机能效，还会带来漏电风险。在当前倡导节能减排、采用清洁能源的趋势下，应该逐渐把低能效的电加热部件取消。在室外换热器下方的接水盘设置冷媒管路，从而采用温度较高的冷媒来对接水盘进行加热能够替代电加热器的作用是可行的方案，但额外增加的冷媒管路也会导致空调器的冷媒回路复杂，温度控制不够精准，降低整机能效。
基于此，本申请的实施例提供一种空调器的运行控制方法、空调器、运行控制装置及计算机可读存储介质，构建简洁的冷媒回路实现采用冷媒对接水盘进行加热，且具有较好的控温效果，能够提升整机能效。
下面结合附图，对本申请的实施例作进一步阐述。
图1是本申请的实施例提供的空调器的系统原理图。参照图1，本申请的第一方面实施例提供一种空调器，包括压缩机100、四通阀200、室内换热器300、室外换热器400、热气旁通管500、节流装置600、第一电磁阀700和第二电磁阀800，其中：
四通阀200的第一端与压缩机100的排气口连接；四通阀200的第四端与压缩机100的回气口连接；室内换热器300的一端与四通阀200的第二端连接；室外换热器400的一端与四通阀200的第三端连接；可以理解的是，当空调器与运行于制热状态，四通阀200处于导通其第一端与第二端以及导通其第三端与第四端的状态，此时从压缩机100的排气口出来的高温高压冷媒经从四通阀200的第一端进入四通阀200，并从四通阀200的第二端传输至室内换热器300，同时，从室外换热器400出来低温低压冷媒从四通阀200的第三端进入四通阀200，并从四通阀200的第四端回流至压缩机100的回气口，参见图1中的虚线箭头所示；当空调器与运行于制冷状态，四通阀200处于导通其第一端与第三端以及导通其第二端与第四端的状态，此时从压缩机100的排气口出来的高温高压冷媒经从四通阀200的第一端进入四通阀200，并从四通阀200的第三端传输至室外换热器400，同时，从室内换热器300出来低温低压冷媒从四通阀200的第二端进入四通阀200，并从四通阀200的第四端回流至压缩机100的回气口，参见图1中的实线箭头所示；
热气旁通管500设置于室外换热器400底部的接水盘，热气旁通管500的一端与室内换热器300的另一端连接；节流装置600的一端与室外换热器400的另一端连接；第一电磁阀700的一端连接至室内换热器300与热气旁通管500的连接点，第一电磁阀700的另一端连接至节流装置600的另一端；第二电磁阀800的一端连接至节流装置600与第一电磁阀700的连接点，第二电磁阀800的另一端连接至热气旁通管500的另一端。
根据本申请的实施例提供的空调器，通过在室外换热器400底部的接水盘设置热气旁通管500，从而可以在室外换热器400底部的接水盘中的水存在结冰风险的情况下，将高温的冷媒流向热气旁通管500对接水盘进行加热，其中采用第一电磁阀700和第二电磁阀800配合热气旁通管500实现冷媒管路的改动，热气旁通管500的一端直接与室内换热器300连接，第一电磁阀700连接在室内换热器300和热气旁通管500的连接点与节流装置600之间，第二电磁阀800则连接在第一电磁阀700和节流装置600的连接点与热气旁通管500之间，从而构建了简洁的冷媒回路；当第一电磁阀700开通时，冷媒可以直接从室内换热器300经由第一电磁阀700流向节流装置600，或者从节流装置600经由第一电磁阀700流向室内换热器300；当第二电磁阀800开通且第一电磁阀700关断时，温度较高的冷媒可以从室内换热器300流向热气旁通管500从而对接水盘进行加热，然后经由第二电磁阀800流向节流装置600，再流向室外换热器400；通过该第一电磁阀700、第二电磁阀800配合热气旁通管500所构建的冷媒回路简洁且控制简单，具有较好的控温效果，能够提升整机能效。
在本申请一些实施例提供的空调器中，节流装置600为电子膨胀阀。可以理解的是，电子膨胀阀是一种可按预设程序进入制冷装置的制冷剂流量的节流元件，在一些负荷变化剧烈或运行工况范围较宽的场合，毛细管、热力膨胀阀等传统的节流元件已不能满足舒适性及节能方面的要求，而电子膨胀阀可以很好地满足要求。
参照图2，本申请的第二方面实施例提供一种应用于如上第一方面实施例的空调器的运行控制方法，包括但不限于步骤S210至步骤S220：
步骤S210：获取空调器的运行模式和室外环境温度；
步骤S220：当空调器运行于制热模式，且室外环境温度小于第一预设值，控制第一电磁阀700关闭以及控制第二电磁阀800打开。示例性地，第一预设值可以设置为0℃。
根据本申请的实施例提供的运行控制方法，当空调器运行于制热模式且室外环境温度较低，例如室外环境温度低于0℃，表示当前运行状态下室外换热器400底部的接水盘中的水具有较大的结冰风险，此时通过控制第一电磁阀700关闭，使得从压缩机100的排气口排出来的高温高压冷媒经过室内换热器300后无法经由第一电磁阀700流向节流装置600，而是先流向热气旁通管500对室外换热器400底部的接水盘进行加热，同时还控制第二电磁阀800打开，使得从热气旁通管500流出的冷媒可以顺利经由第二电磁阀800流向节流装置600，再流向室外换热器400，冷媒流向参照图1中的虚线箭头所示，实现利用空调器中的高温冷媒来防止室外换热器400底部的接水盘结冰，能够提升整机能效。
在本申请一些实施例提供的运行控制方法中，还包括：当空调器运行于制冷模式，控制第一电磁阀700打开以及控制第二电磁阀800关闭。
可以理解的是，制冷模式下，从压缩机100的排气口出来的高温高压冷媒经从四通阀200的第一端进入四通阀200，并从四通阀200的第三端传输至室外换热器400，再经过节流装置600，由于第二电磁阀800关闭以及第一电磁阀700打开，冷媒直接经过第一电磁阀700后进入室内换热器300进行换热，冷媒流向参见图1中的实线箭头所示，热气旁通管500中没有冷媒流动，不参与冷媒循环和换热；从室内换热器300出来低温低压冷媒从四通阀200的第二端进入四通阀200，并从四通阀200的第四端回流至压缩机100的回气口。
在本申请一些实施例提供的运行控制方法中，还包括：当空调器运行于制热模式，且室外环境温度大于或等于第一预设值，控制第一电磁阀700打开以及控制第二电磁阀800关闭。示例性地，第一预设值可以设置为0℃。
在本实施例中，当空调器运行于制热模式且室外环境温度高于0℃，表示当前运行状态下室外换热器400底部的接水盘中的水不存在结冰风险，从压缩机100的排气口出来的高温高压冷媒经从四通阀200的第一端进入四通阀200，并从四通阀200的第二端传输至室内换热器300，由于第一电磁阀700打开，冷媒直接经过第一电磁阀700，再进入节流装置600后进入室外换热器400进行换热，还由于第二电磁阀800关闭，因此热气旁通管500中没有冷媒流动，不参与冷媒循环和换热；从室外换热器400出来低温低压冷媒从四通阀200的第三端进入四通阀200，并从四通阀200的第四端回流至压缩机100的回气口。
在本申请一些实施例提供的运行控制方法中，在第一电磁阀700关闭以及第二电磁阀800打开的情况下，获取热气旁通管500的管温，并根据管温调节节流装置600的开度。
在本实施例中，第一电磁阀700关闭以及第二电磁阀800打开的情况，也即需要利用空调器中的高温冷媒来防止室外换热器400底部的接水盘结冰的情况，因此热气旁通管500的管温需要足够高，才能够实现对室外换热器400底部的接水盘进行加热的作用，因此根据管温调节节流装置600的开度，能够保障热气旁通管500的管温足够高。具体地，当管温小于第二预设值，减小节流装置600的开度。示例性地，第二预设值设置为20℃。因此，当热气旁通管500的管温低于20℃，减小节流装置600的开度，能够使得更多的高温冷媒积聚在热气旁通管500中，有利于提高热气旁通管500的管温。
在本申请一些实施例提供的运行控制方法中，当管温大于或等于第二预设值，控制节流装置600的开度保持不变。
可以理解的是，当管温大于或等于第二预设值，例如为大于或等于20℃，表示当前的热气旁通管500的管温足够高，对室外换热器400底部的接水盘具有较好的加热效果，此时控制节流装置600的开度保持不变，无需调整冷媒流量。
下面结合图3，对本申请的实施例提供的空调器在制热模式下的运行控制方法进行具体的介绍：
步骤S301：制热模式开启；此时四通阀200处于导通其第一端与第二端以及导通其第三端与第四端的状态，此时从压缩机100的排气口出来的高温高压冷媒经从四通阀200的第一端进入四通阀200，并从四通阀200的第二端传输至室内换热器300；跳转至步骤S302；
步骤S302：获取室外环境温度T4；跳转至步骤S303；
步骤S303：判断室外环境温度T4是否小于0℃？若是，则跳转至步骤S305；若否，则跳转至步骤S304；
步骤S304：控制第一电磁阀700打开，以及控制第二电磁阀800关闭；跳转至步骤S302；
步骤S305：控制第一电磁阀700关闭，以及控制第二电磁阀800打开；跳转至步骤S306；
步骤S306：热气旁通管500对室外换热器400底部的接水盘进行加热；此时，从压缩机100的排气口排出来的高温高压冷媒经过室内换热器300后无法经由第一电磁阀700流向节流装置600，而是先流向热气旁通管500对室外换热器400底部的接水盘进行加热，同时还控制第二电磁阀800打开，使得从热气旁通管500流出的冷媒可以顺利经由第二电磁阀800流向节流装置600，再流向室外换热器400，实现利用空调器中的高温冷媒来防止室外换热器400底部的接水盘结冰；跳转至步骤S307；
步骤S307：获取热气旁通管500的管温Tg；跳转至步骤S308；
步骤S308：判断热气旁通管500的管温Tg是否小于20℃？若是，则跳转至步骤S309；若否，则跳转至步骤S310；
步骤S309：减小节流装置600的开度；此时能够使得更多的高温冷媒积聚在热气旁通管500中，有利于提高热气旁通管500的管温；
步骤S310：保持节流装置600的开度；此时表示当前的热气旁通管500的管温足够高，对室外换热器400底部的接水盘具有较好的加热效果，此时控制节流装置600的开度保持不变，无需调整冷媒流量。
在本实施例中，空调器通过在室外换热器400底部的接水盘设置热气旁通管500，从 而可以在室外换热器400底部的接水盘中的水存在结冰风险的情况下，将高温的冷媒流向热气旁通管500对接水盘进行加热，其中采用第一电磁阀700和第二电磁阀800配合热气旁通管500实现冷媒管路的改动，热气旁通管500的一端直接与室内换热器300连接，第一电磁阀700连接在室内换热器300和热气旁通管500的连接点与节流装置600之间，第二电磁阀800则连接在第一电磁阀700和节流装置600的连接点与热气旁通管500之间，从而构建了简洁的冷媒回路；当第一电磁阀700开通时，冷媒可以直接从室内换热器300经由第一电磁阀700流向节流装置600；当第二电磁阀800开通且第一电磁阀700关断时，温度较高的冷媒可以从室内换热器300流向热气旁通管500从而对接水盘进行加热，然后经由第二电磁阀800流向节流装置600，再流向室外换热器400；通过该第一电磁阀700、第二电磁阀800配合热气旁通管500所构建的冷媒回路简洁且控制简单，具有较好的控温效果，能够提升整机能效；具体地，当空调器运行于制热模式且室外环境温度较低，例如室外环境温度低于0℃，表示当前运行状态下室外换热器400底部的接水盘中的水具有较大的结冰风险，此时通过控制第一电磁阀700关闭，使得从压缩机100的排气口排出来的高温高压冷媒经过室内换热器300后无法经由第一电磁阀700流向节流装置600，而是先流向热气旁通管500对室外换热器400底部的接水盘进行加热，同时还控制第二电磁阀800打开，使得从热气旁通管500流出的冷媒可以顺利经由第二电磁阀800流向节流装置600，再流向室外换热器400，冷媒流向参照图1中的虚线箭头所示，实现利用空调器中的高温冷媒来防止室外换热器400底部的接水盘结冰，能够提升整机能效。
