摘要：

A new idea of "no frost effect" is proposed in this paper, which uses the technical scheme of waste heat storage and waste heat defrosting to realize the non-attenuation of heat supply during defrosting, so that users do not feel the comfort problem brought by traditional defrosting. According to this idea, a new heat storage air source heat pump system was proposed and the experimental apparatus was built up, and its heating and defrost effects were actually tested under the rain and snow weather (high humidity environment) in March in Jilin city. The results show that the pressure and compression ratio of the new system change steadily remain at an ideal level during defrosting and gain complete defrosting effect. The air temperature at the outlet of the indoor unit does not decrease but also increases during defrosting, which realizes the goal of "no frost effect". © 2021, Solar Energy Periodical Office Co., Ltd.
