Heat pump architecture for improving heating performance

A refrigerant circuit for a thermal management system and a method of operating the same are disclosed. The refrigerant circuit comprises a compressor, a condenser, an economizer, and an evaporator. The compressor has a discharge side, a suction side, and an injection side. A first bypass recirculation discharge fluid line for selectively providing fluid communication between the discharge side and the injection side of the compressor, and a second bypass recirculation discharge fluid line for selectively providing fluid communication between the discharge side and the suction side of the compressor.
