Description
本申请要求于2017年1月10日提交中国专利局、申请号为2017100165559、发明名称为“化霜控制方法、化霜控制***和空调器”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。This application claims the priority of the Chinese Patent Application filed on January 10, 2017, the Chinese Patent Office, the application number is 2017100165559, and the invention name is "defrosting control method, defrosting control system and air conditioner", the entire contents of which are incorporated by reference. Combined in this application.
本发明涉及空调器技术领域,具体而言,涉及一种化霜控制方法、化霜控制***和空调器。The present invention relates to the field of air conditioner technology, and in particular to a defrosting control method, a defrosting control system, and an air conditioner.
相关技术中的空调器通常利用压缩机的排气温度进行热气冲霜,在开始除霜时,四通阀换向,使室外换热器放热,室内换热器吸热,造成室内环境温度降低,这样在较冷的环境中,空调器运行制冷循环,会导致房间温度忽冷忽热,影响用户的舒适度;而且除霜过程中由于室外换热器下部的霜较难除净,在上半部分己经除霜完毕时,必须要等到室外换热器下部分除霜完全才能够同时完成除霜而进入正常的制热运行状态,因此浪费了一部分热量,并延长了除霜过程,减少了制热量并降低了总体制热效果。The air conditioner in the related art usually uses the exhaust temperature of the compressor to perform hot air blasting. When the defrosting starts, the four-way valve reverses to make the outdoor heat exchanger radiate heat, and the indoor heat exchanger absorbs heat, causing indoor indoor temperature. Reduce, so in a colder environment, the air conditioner operates the refrigeration cycle, which will cause the room temperature to be hot and cold, affecting the user's comfort; and the frost in the lower part of the outdoor heat exchanger is more difficult to remove during the defrost process. When the upper part has been defrosted, it must wait until the defrosting of the outdoor heat exchanger is completed before the defrosting can be completed at the same time and enter the normal heating operation state, thus wasting a part of the heat and prolonging the defrosting process. Reduces heat and reduces overall heating.
