摘要:In order to solve the serious frosting problem of air source heat pump in high humidity area in winter,a set of air source heat pump was tested and studied.The experimental results showed that the frost condition in winter in study area started when the outdoor temperature was less than 6℃ and the relative humidity was more than 75%.The blocking experiment proved that frost formation was beneficial to the operation of the unit when the blocking degree was less than 10%.Furthermore,by extending the initial time of frosting,a new method of frost suppression was proposed,which extended the initial time of frosting by 22 minutes.In the high humidity area,air source heat pump was recommended to be used for heating when it is above 8℃ in winter,while the staged frost suppression was considered when it is below 6℃ to improve the performance of air source heat pump.
