Refrigeration and dehumidification integrated air conditioning system based on waste heat utilization and working method thereof

Abstract

The invention discloses a refrigeration and dehumidification integrated air conditioning system based on waste heat utilization and a working method thereof. Industrial low-grade waste heat (solar energy, smoke, steam, hot water and the like) serves as energy input, and independent control over temperature and humidity of the air conditioning system is achieved. The refrigeration and dehumidification integrated air conditioning system comprises an air heat recovery heat exchanger, a diaphragm type liquid dehumidification assembly, a radiator, a dry air cooling coiled pipe, a humidifier and a LiBr refrigeration unit, the refrigerant water supply and return temperature of the LiBr refrigeration unit can be increased, and the level of energy efficiency of the LiBr refrigeration unit is improved; a dehumidification solution achieves regeneration through a generator of the LiBr refrigeration unit, and equipment investment and system operation maintaining cost are reduced; and the process that in a traditional refrigeration and dehumidification technology, reheating is conducted after cooling is canceled, and the energy consumption level of the air conditioning system is substantially reduced. In China, the refrigeration and dehumidification integrated air conditioning system is applied and popularized in the South high in temperature and humid, and has great energy-saving potentialand an effect of balancing the power grid peak load.

Description

technical field [0001] The invention relates to an integrated refrigeration and dehumidification air-conditioning system, which mainly uses industrial low-grade waste heat to drive a LiBr refrigeration unit, and uses membrane liquid dehumidification technology to perform integrated refrigeration and dehumidification of air, and belongs to the technical field of refrigeration and dehumidification air conditioning. Background technique [0002] Freezing dehumidification is the most widely used dehumidification technology at present. It condenses the water in the air by cooling, then heats the air to a comfortable temperature and sends it indoors. The freezing dehumidification method requires cooling and then heating up, and cannot achieve independent control of temperature and humidity, resulting in extremely high energy consumption in the traditional refrigeration and dehumidification process. Therefore, the integrated technology of LiBr refrigeration unit and membrane liquid...
