Control method for delaying frosting of condenser outside vehicle

Abstract

The invention discloses a control method and a control system for delaying frosting of a condenser outside a vehicle. The control method for delaying frosting of the condenser outside the vehicle provided by the invention prestores heat pump power calibrated according to environment temperature Tam, environment humidity H and heat pump air inlet temperature Tein, and monitors working parameters PXO and TXO of the condenser outside the vehicle when a heat pump system works; and if it is found that the condenser outside the vehicle has the frosting risk, the power of the heat pump is reduced, and the new power of the heat pump is obtained from a heat pump limiting power meter according to the environment temperature, the heat pump air inlet temperature and the environment temperature detected by the current working condition, so that the frosting risk of the condenser outside the vehicle is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle heat pump systems, in particular to a control method for delaying frosting of a condenser outside the vehicle. Background technique [0002] At present, electric vehicles are becoming more and more popular, and the vehicle heat pump air-conditioning system, as a new type of air-conditioning application technology, is gradually being applied to vehicle air-conditioning. The heat pump air conditioning system usually has several specific modes according to different seasons. When using it, the customer first selects the mode, and the heat pump air conditioning system performs corresponding work according to the mode selected by the customer to meet the needs of different temperatures in the car to obtain a comfortable car. Internal environment. [0003] At present, when the heat pump system works in the heating mode in an environment with low external temperature and high humidity, frosting often oc...

AI Technical Summary

Problems solved by technology

[0003] At present, when the heat pump system works in the heating mode in an environment with low external temperature and high humidity, frosting often occurs on the condenser outside the vehicle. When the condenser outside the vehicle is frosted, the heat pump system cannot operate normally, and the operating effect of the heat pump system will greatly reduce
