Abstract
A method and system for discharging refrigerant, such as carbon dioxide, from an air conditioning system. The discharge rate of the refrigerant from the air conditioning system is controlled by a discharge rate controller, even as refrigerant pressure at the system input varies. By maintaining discharge rate at a controlled value, the discharge time of the refrigerant from the air conditioning system is reduced.
