System for Controlling Dual Compressors in an Automotive HVAC System

A system for controlling dual compressors in an automotive Heating, Ventilation, and Air Conditioning (HVAC) system, comprising:

• a. a control logic module (101), wherein the control logic module (101) receives one or more input signals indicative of a cabin Air Conditioning (AC) request status, a cabin cooling demand, and a battery cooling demand;
• b. a plant model (102) operatively coupled to the control logic module (101), wherein the plant model (102) computes one or more operational parameters including a first compressor speed, a second compressor speed, and a corresponding plurality of expansion valve positions in response to the cabin cooling demand and a battery cooling demand;
• c. a power calculation module (103), wherein the power calculation module (103) calculates power consumption based on a speed of the first compressor and the second compressor and thermal load, thus selecting a minimum power consumption value;
• d. a feedback mechanism (104), wherein the feedback mechanism (104) ensures compliance with safety and performance criteria by comparing the compressor speed with at least one of a condenser pressure, a chiller pressure, and an optimal Coefficient of Performance (COP);
• and
• e. a plurality of actuators (105), wherein the plurality of actuators (105) regulate the first compressor speed, the second compressor speed, and the expansion valve positions in accordance with one or more outputs generated by the control logic module (101);
• wherein the system (100) optimizes power consumption by selecting a minimum energy requirement, computed as a function of the first compressor speed, the second compressor speed and associated thermal loads, for efficient operation of a vehicle.
