Solar energy driving compaction type two-stage parallel connection liquid dehumidifying air conditioner

Abstract

A compact-type liquid dehumidification air conditioner in two-stage parallel connection which is driven by the solar energy comprises a two-stage dehumidification module, a regeneration module, a first evaporation cooling device, a cross flow heat exchanger and a second evaporation cooling device. The two-stage dehumidification module, the cross flow heat exchanger and two evaporation cooling devices constitute the upper layer of the solar compact type of liquid dehumidification air conditioner in two-stage parallel connection; the regeneration module constitutes the lower layer of the liquid dehumidification air conditioner. The modules are connected through the liquid pipeline or the air duct. Compared with the traditional liquid dehumidification air conditioner, the layered design of the air conditioner saves the space greatly; the parallel arrangement of the dehumidification module is convenient for the regulation of the gas and liquid flow ratio of each level; the operation with big concentration difference is in favor of the complete exertion of the liquid dehumidification capability, which realizes the energy storage and saving purpose. Therefore the compact-type liquid dehumidification air conditioner in two-stage parallel connection which is driven by the solar energy improves the deterioration of the dehumidification effect due to the gas liquid mixing heat during the dehumidification process.

Description

technical field [0001] The invention relates to a dehumidification air conditioner in the technical field of refrigeration engineering, in particular to a solar-driven compact two-stage parallel liquid dehumidification air conditioner. Background technique [0002] Liquid dehumidification air conditioners have the advantages of being able to independently handle the temperature and humidity of the air, and being driven by low-temperature pyrogens. Compared with the traditional central air conditioner, its operating cost is reduced by 40%, and the accuracy of air humidity control is higher. It avoids the pollution caused by condensation water in the indoor cooling coil, has a bactericidal effect, and ensures better indoor air quality. Liquid dehumidification air-conditioning is an environmentally friendly air-conditioning method, without CFCS problems and cultural and historical effects, and can be driven by low-grade heat sources such as solar energy and industrial wastewate...

Problems solved by technology

[0003] The current liquid dehumidification air conditioner has the following disadvantages: 1) high regeneration energy consumption, 2) poor energy storage effect, 3) complex structure when combined with heat pump system

[0004] After searching the literature of the prior art, it is found that the Chinese patent (application) No. 02144128.6 is "multi-stage liquid dehumidification method". In this technology, the treatment wind passes through the multi-stage solution dehumidifier successively. ) and high power consumption, it is impossible to effectively control the outlet air temperature at all levels, and the required air temperature adjustment range cannot be guaranteed
