Abstract: Способ управления кондиционером, содержащий определение условий образования инея на внутреннем блоке во время работы кондиционера в режиме охлаждения (S301), когда внутренний блок в режиме охлаждения покрывается инеем, система управления перекрывает поток в трубе для хладагента в направлении внутреннего блока (S302). Данный способ управления, при котором перекрывается поток в трубе для хладагента в направлении покрывающегося инеем теплообменника, позволяет остановить непрерывный ввод низкотемпературного хладагента в покрывающийся инеем теплообменник, тем самым предотвращая усугубление проблемы образования инея и позволяя теплообменнику разморозиться естественным способом при температуре среды его нахождения, чтобы защитить теплообменник кондиционера от заморозки. Также будет раскрыто одно из устройств управления кондиционером. 4 н. и 7 з.п. ф-лы, 4 ил.
