Description

technical field [0001] The invention relates to the technical field of refrigeration and air conditioning equipment, in particular to a boiling regeneration type solution dehumidification system driven jointly by solar energy and ground source energy. Background technique [0002] Dehumidification is the basic task in air-conditioning engineering. The commonly used condensation dehumidification method has higher requirements on the temperature of the cold source, and it is easy to produce a large cold and heat offset phenomenon due to the overcooling of the treated air. The solution dehumidification can effectively overcome this shortcoming. The system uses the water vapor partial pressure difference between the air and the solution surface as the driving force to complete the transfer of water vapor between the solution and the air, thereby realizing the cyclic process of air dehumidification and solution regeneration, so there is no need to dew point temperature of the air ...

Problems solved by technology

The common feature of these systems is thermal drive, that is, all the work required by the drive system is borne by the heat energy input by the generator, which makes the temperature of the driving heat source higher. In addition, this thermal drive mode cannot be used for shallow surface water sources. The use of natural cold sources that are ubiquitous in soil sources has affected its scope of application. Therefore, it is necessary to develop a boiling system that can use both natural heat sources and natural cold sources to jointly drive the system and expand the utilization range of low-grade cold and heat sources.
