キレン基含有シラン化合物は融氷性能に問題があった。A silane having an alkoxy group such as a methoxy group or an ethoxy group as a hydrolyzable group does not have the ability to melt ice, and it is necessary to add methanol or ethanol as an ice melting agent. Such alcohols have a problem in that the performance of the refrigerant is reduced. Further, when an organic silane compound having an amino group, a mercapto group, an acyloxy group, or the like is used, there is a problem that the refrigerant unit is corroded by amine, mercaptan, or acid generated by hydrolysis. Further, the polyoxyalkylene group-containing silane compound has a problem in ice melting performance.
