Abstract
"COMPRESSOR HERMéTICO DE REFRIGERAçãO COM CONVERSOR DE CORRENTE CONTìNUA PARA CORRENTE ALTERNADA EM BAIXA TENSãO". Trata-se de um compressor hermético de refrigeração ( 1 ) adaptado elétrica e mecanicamente para uso em veículos automotivos ou náuticos. Constituído de um compressor de 110 ou 220 Vca deu uso residencial de qualquer marca ou modelo, monofásico ou trifásico, no qual é alterado o seu enrolamento para funcionar em corrente alternada abaixo de 54 volts. Um sistema de molas ( 2 ) é adaptado para evitar ruídos e vibrações excessivas. Para acionar o compressor ( 1 ) em corrente alternada de baixa tensão foi desenvolvido um conversor de corrente continua em corrente alternada ( 6 ) de baixa tensão. A energia elétrica de alimentação para o sistema é oriunda de baterias ( 17 ) que a fornecem em corrente contínua entre 12 e 54 volts. O conversor de corrente contínua em corrente alternada (6) desenvolvido especificamente para o compressor de corrente alternada de baixa tensão conta com diversos circuitos especiais. O circuito de partida ( 10 ) tem por função fornecer o comando para o acionamento da bobina auxiliar do motor ( 15 ) que inicia o movimento de rotação do motor ( 1 ). Depois que o motor atinge a rotação normal o circuito de partida ( 10 ) desativa a bobina de partida ( 15 ) O circuito de sobrecarga ( 9 ) tem a função de identificar se a operação do motor ( 1 ) está fora dos parâmetros normais de funcionamento e então desligar automaticamente o sistema. O circuito de sub-tensão (8) tem a função de inibir o funcionamento do sistema caso a tensão das baterias ( 17 ) esteja em níveis abaixo do ideal para o correto funcionamento do motor ( 1 ). Todas as funções alimentam o gerenciador eletrónico ( 13 ) que por sua vez habilita ou inibe o circuito de potencia ( 12 ) e o circuito de Freq³ência ( 11 ). O circuito de potência ( 12 ) e o circuito de freq³ência ( 11 ) têm a função de, uma vez habilitado pelo gerenciador eletrónico ( 13 ), proporcionar ao motor ( 1 ) a potência e a freq³ência corretas."HERMETIC COOLING COMPRESSOR WITH LOW VOLTAGE CURRENT CONVERTER". It is an airtight refrigeration compressor (1) electrically and mechanically adapted for use in automotive or marine vehicles. Consisting of a 110 or 220 Vac compressor it has made residential use of any make or model, single or three phase, in which its winding is changed to operate on alternating current below 54 volts. A spring system (2) is adapted to prevent excessive noise and vibration. To drive the low voltage alternating current compressor (1) a low voltage alternating current converter (6) has been developed. The electrical power supply to the system comes from batteries (17) that supply it with direct current between 12 and 54 volts. The direct current to alternating current converter (6) developed specifically for the low voltage alternating current compressor has several special circuits. The starting circuit (10) has the function of providing the command for the activation of the motor auxiliary coil (15) which initiates the motor rotation movement (1). After the motor reaches normal speed the starting circuit (10) deactivates the starting coil (15). The overload circuit (9) has the function of identifying if the motor operation (1) is outside normal operating parameters. and then automatically shut down the system. The undervoltage circuit (8) has the function of inhibiting the system operation if the battery voltage (17) is below ideal levels for the correct operation of the motor (1). All functions feed the electronic manager (13) which in turn enables or inhibits the power circuit (12) and the Frequency circuit (11). The power circuit (12) and the frequency circuit (11) have the function, once enabled by the electronic manager (13), to provide the motor (1) with the correct power and frequency.
