Novel solution type dual-cold-source household ceiling unit

Abstract

The invention discloses a novel solution type dual-cold-source household ceiling unit. The novel solution type dual-cold-source household ceiling unit comprises a case, a mounting plate, a fresh air hole, an air feeding hole, an air exhaust hole, an air return hole, a partition, a filter, a first fan, an evaporator, a re-heater, a second fan, a third fan, a regenerating module, a surface cooler and a dehumidification module. The novel solution type dual-cold-source household ceiling unit disclosed by the invention is equipped with the surface cooler and the dehumidification module, and freezing dehumidification of the surface cooler and solution dehumidification of the dehumidification of module can be combined in use; the surface cooler utilizes freezing dehumidification to perform pre-dehumidification on fresh air, and a lithium bromide solution inside the dehumidification module performs further dehumidification on pre-dehumidified fresh air; and moreover, solubility of the lithiumbromide solution is 40%-50%, so that the dehumidification module can achieve better dilution effect, and therefore, the problems that frozen dehumidified air in the prior art is relatively high in dewpoint, solution dehumidification needs a regenerating heat source, and the unit size is relatively great are solved.

Description

technical field [0001] The invention relates to the related field of ceiling units, in particular to a novel solution type double cold source household type ceiling unit. Background technique [0002] Since entering the 21st century, my country's air-conditioning industry has continued to develop. Reform and opening up has driven the rapid development of the domestic economy. Customers have higher and higher requirements for healthy and environmentally friendly fresh air equipment. The main task of the air-conditioning system for civil buildings is to meet the appropriate indoor temperature and humidity. The air dehumidification process is an important part of it. At present, the commonly used dehumidification methods and systems can be roughly divided into cooling dehumidification and chemical dehumidification. The representatives are condensation dehumidification and solution dehumidification. Wait for the refrigerant to cool the air below the dew point temperature, so that ...

AI Technical Summary

Problems solved by technology

[0003] Therefore, in order to solve the above-mentioned shortcomings, the present invention provides a new solution-type dual-cooling source household ceiling unit to solve the problem of high air dew point after freezing and dehumidification in the prior art, solution dehumidification requires regeneration heat source, and the unit volume is relatively large The problem
