Abstract

The invention provides a series solar collector tube generator and an absorption refrigeration air-conditioning system consisting of the same. The series solar collector tube generator comprises a solar vacuum collector tube generator unit and a solar vacuum collector tube separator unit, wherein a liquid outlet tube of at least one vacuum collector tube generator unit and a liquid inlet tube of at least one solar vacuum collector tube separator unit are connected end to end to form the series solar collector tube generator. The series solar collector tube generator, a gas-liquid exchanger, a solution exchanger, a solution pump, an absorber, an evaporator, a condenser and a throttle valve are connected to form the absorption refrigeration air-conditioning system. The series solar collector tube generator is not provided with a water tank and does not carry out secondary heat exchange, thereby improving the heat energy utilization of the system, saving the space and reducing the cost. A generator device of the absorption refrigeration air-conditioning system and a solar vacuum collector tube are closely combined to collect heat, store heat and separate gas and liquid of a solution simultaneously, thereby effectively improving the heat efficiency of solar utilization, obtaining higher generating temperature and greatly improving the energy efficiency ratio of the system.
