Abstract

SISTEMA DE BOMBA DE CARREGAMENTO PARA SUPRIR UM FLUIDO DE TRABALHO A MANCAIS EM UM CIRCUITO DE FLUIDO DE TRABALHO SUPERCRÍTICO. São fornecidos, no presente documento, um sistema de motor térmico e um método para gerar energia, tal como transformar energia térmica em energia mecânica e/ou energia elétrica. O sistema de motor térmico pode ter uma única bomba de carregamento para implantar de modo eficiente pelo menos duas tarefas independentes. A bomba de carregamento pode ser utilizada para remover fluido de trabalho (por exemplo, CO2) de e/ou adicionar fluido de trabalho em um circuito de fluido de trabalho durante controle de estoque do fluido de trabalho. A bomba de carregamento pode ser utilizada para transferir ou entregar de outra maneira o fluido de trabalho como um agente de resfriamento a mancais contidos dentro de um alojamento de mancal de um componente de sistema durante um processo de arranque. O sistema de motor térmico também pode ter um tanque de controle de massa utilizado com a bomba de carregamento e configurado para receber, armazenar e distribuir o fluido de trabalho.CHARGING PUMP SYSTEM TO SUPPLY A WORKING FLUID TO BEARINGS IN A SUPERCRITICAL WORKING FLUID CIRCUIT. Provided herein are a heat engine system and a method for generating energy, such as transforming thermal energy into mechanical energy and/or electrical energy. The heat engine system can have a single charging pump to efficiently deploy at least two independent tasks. The charge pump can be used to remove working fluid (eg CO2) from and/or add working fluid into a working fluid circuit during working fluid inventory control. The charging pump may be used to transfer or otherwise deliver the working fluid as a coolant to bearings contained within a bearing housing of a system component during a start-up process. The heat engine system may also have a mass control tank used with the charging pump and configured to receive, store and distribute the working fluid.
