An environmental control system includes a refrigerant circuit (102) with a pump segment (156) and an evaporator segment (150), an evaporator (144) arranged along the evaporator segment and in fluid communication with of the refrigerant circuit, and a coolant circuit (104). The coolant circuit extends through the evaporator and is thermally coupled to refrigerant circuit by the evaporator, the coolant circuit including a first segment and a second segment arranged in parallel with one another to transfer heat from a first zone to a first portion of liquid coolant traversing the coolant circuit and transfer additional heat from a second zone to a second portion of coolant traversing the coolant circuit. Aircraft and environmental control systems are also described.
