摘要：
A novel two-stage parallel desiccant coated heat pump system is proposed, the system performance is experimentally studied under air typical conditions. The experiments show that the system can effectively solve the problem of insufficient handling capacity of the sensible heat load of the solid desiccant coated heat pump(SDHP), the sensible and latent heat load can be flexibly deployed in different ratio: it can provide 19.0℃ and 8.81 g/kg of air supply in the comfort zone under typical air conditions, the average COP reached 3.92 under the condensing temperature of 50℃. The COP risen from 3.39 to 5.81 when the condensing temperature changed from 55℃ to 35℃, the sensible heat load ratio is always maintained above 16: 1. The latent load ratio of the system in different environments can reach 7%—60%, which can meet the requirements of temperature and humidity decoupling in most air supply conditions. © 2023 Chemical Industry Press.
