Solution dehumidification type indirect evaporation fresh air handling unit based on solar driving

Abstract

The invention discloses a solution dehumidification type indirect evaporation fresh air handling unit based on solar energy driving. A return air inlet, a return air filtering section, a heat pipe condensation end, a solution regeneration section and an axial flow fan are sequentially arranged in a unit shell in the flowing direction of return air after the return air enters the unit shell; a fresh air inlet, a fresh air filtering section, a heat pipe evaporation end, a solution dehumidification section, an indirect evaporation section, a solution cooler, a fresh air heat exchanger, an air supply section and a fresh air supply outlet are sequentially arranged in the unit shell in the flowing direction of fresh air after the fresh air enters the unit shell. A solar heat collection device is installed on the top of the unit shell. Compared with an existing fresh air handling unit, the fresh air handling unit protected by the invention has the advantages that cold energy is recycled through the heat pipe, fresh air is humidified through the solution dehumidification section, and fresh air refrigeration is realized through the indirect evaporation section; and then the fresh air heat exchanger is assisted to be used for fresh air refrigeration or dehumidification constant-temperature operation under different meteorological conditions and working modes, and compared with a traditional electric refrigeration air conditioning system, the system energy consumption is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of fresh air air conditioners, in particular to a solution dehumidification type indirect evaporation fresh air unit driven by solar energy. Background technique [0002] With the development of economic construction, especially various precision processing industries, garment factories, and grain processing enterprises, it is necessary to provide cooling or heating for factory buildings. When cooling or heating these areas, traditional chillers or heat pump units and combined air-conditioning units are often required. The operation mode is single, the energy consumption is huge, and the operation and maintenance costs are high. [0003] Under the background of the country’s proposal of carbon peaking and carbon neutrality, it is necessary to make full use of natural cold sources, do a good job of cold recovery or heat recovery, and cool down or heat large spaces such as factories through solution dehumidifi...
