The embodiment of the invention provides a defrosting control method, a vehicle thermal management system, a vehicle and a medium. The method is applied to a vehicle heat management system, the vehicle heat management system comprises an air source heat pump air-conditioning system, and the air source heat pump air-conditioning system comprises an air-cooled condenser. The method comprises the following steps: determining a frosting risk coefficient by utilizing a frosting risk coefficient model according to an obtained outdoor temperature, outdoor humidity and a scene type; determining a frosting treatment type according to the frosting risk coefficient; and under the condition that the frosting treatment type is a defrosting treatment type, if it is determined that the outdoor temperature and the obtained working information of the vehicle heat management system meet the defrosting treatment condition, a defrosting mode is started, and an air-cooled condenser is subjected to defrosting treatment. According to the invention, the problems of high energy consumption and low heating efficiency of a vehicle heat management system due to the fact that the condition of defrosting mistake is easy to occur when whether the air-cooled condenser is defrosted or not is determined according to the outdoor temperature and the refrigerant temperature in the related technology are solved.

    本申请实施例提供一种化霜控制方法、车辆热管理系统、车辆及介质。该方法应用于车辆热管理系统,车辆热管理系统包括空气源热泵空调系统,空气源热泵空调系统包括风冷冷凝器。该方法中,根据获取的室外温度、室外湿度以及场景类型,利用结霜风险系数模型,确定结霜风险系数;根据结霜风险系数,确定结霜处理类型;在结霜处理类型为化霜处理类型的情况下,若确定室外温度和获取的车辆热管理系统的工作信息满足化霜处理条件,则进入化霜模式,以对风冷冷凝器进行化霜处理。解决了相关技术中根据室外温度和冷媒温度,确定是否对风冷冷凝器化霜,容易出现误化霜的情况,从而导致车辆热管理系统存在能耗高、制热效率低的问题。
