The embodiment of the invention provides a frost suppression control method, a vehicle thermal management system and a vehicle. The vehicle heat management system comprises an air source heat pump air conditioning system and a cooling liquid loop system, the air source heat pump air conditioning system comprises an air-cooled condenser, and the cooling liquid loop system comprises a front heat exchanger, a cooling liquid pump and a heat source. And the front heat exchanger is arranged in front of the air-cooled condenser. The method comprises the following steps: determining a frosting risk coefficient by utilizing a frosting risk coefficient model according to the obtained outdoor temperature, outdoor humidity and scene type; determining a frosting treatment type according to the frosting risk coefficient; and when the frosting treatment type is a frost suppression treatment type, if it is determined that the outdoor temperature meets the frost suppression treatment condition, a cooling liquid pump is controlled to operate, so that cooling liquid is driven to bring heat of a heat source into a front heat exchanger, and frost suppression is conducted on an air-cooled condenser. The problems that the energy consumption of a vehicle heat management system is high and heat cannot be supplied to the interior of a vehicle during defrosting due to a method for only defrosting the air-cooled condenser after frosting in the prior art are solved.
本申请实施例提供一种抑霜控制方法、车辆热管理系统及车辆。车辆热管理系统包括空气源热泵空调系统和冷却液回路系统,空气源热泵空调系统包括风冷冷凝器,冷却液回路系统包括前置换热器、冷却液泵及热源;前置换热器设置于风冷冷凝器前。该方法中,根据获取的室外温度、室外湿度及场景类型,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;结霜处理类型为抑霜处理类型时,若确定室外温度满足抑霜处理条件,控制冷却液泵运行,以驱动冷却液将热源的热量带入前置换热器,以对风冷冷凝器抑霜。解决了相关技术仅能在结霜后对风冷冷凝器化霜的方法,存在的车辆热管理系统能耗高、无法在化霜时对车内进行供热的问题。
