Method for Controlling Vehicle HVAC System - A simplified explanation of the abstract
This abstract first appeared for US patent application 17813381 titled 'Method for Controlling Vehicle HVAC System
Simplified Explanation
The abstract describes a method for controlling the HVAC system of a vehicle by determining a target subcooled temperature of the refrigerant discharged from the compressor outlet. The method involves calculating the change in enthalpy of the refrigerant during the condensing and subcooling process, as well as the change in enthalpy of the air passing over the condenser's exterior surface. The required fan duty of the cooling fan is then calculated based on the calculated air enthalpy change.

Original Abstract Submitted
An embodiment method for controlling a heating, ventilation, and air conditioning (HVAC) system of a vehicle includes determining a target subcooled temperature of a refrigerant based on a temperature and a pressure of the refrigerant discharged from an outlet of a compressor when the compressor operates, calculating a change in enthalpy of the refrigerant based on the determined target subcooled temperature in a process of condensing and subcooling the refrigerant, calculating a change in enthalpy of air passing over an exterior surface of a condenser based on the calculated refrigerant enthalpy change, and calculating a required fan duty of a cooling fan based on the calculated air enthalpy change, wherein the cooling fan is configured to blow the air to the condenser.
