Abstract:
In this paper,a system is studied which treats heat and humidity independently in grade utilization of condensation heat based on solution desiccant. A test bench is set up for a counter flow regeneration process with graded utilization of condensation heat,which simulates secondary utilization of condensation heat through heating air,and establishes the NTU-Le model of the counter flow regenerator. Thus theoretical and experimental studies of the effects of graded condensation heat utilization on regeneration process are carried out. Results show that in the case of the equality of total condensation heat in regeneration process,along with the increase of the ratio of primary utilization of condensation heat and primary utilization of condensation heat,the regeneration rate and regenerative heat efficiency in regeneration process both increase. In the growth progress of primary condensing heat utilization ratio variable φ from 0 to 1,the growth range of regeneration rate and regenerative heat efficiency rises continuously along with the increase of total condensation heat. When Qa,the quantity of condensing heat to heat the air maintains constant,and Qs,the quantity of condensing heat to heat the solution is changed,regeneration amount and regenerative heat efficiency reach a peak respectively. Thus considering that,an appropriate temperature of solution regeneration must be chosen synthetically to achieve better results of regeneration.
