This paper reports the development of a novel solar hybrid desiccant cooling system with heat pipe heat exchanger (HPHE). The aim is to achieve higher efficiency to reduce the use of electricity by utilizing the desiccant dehumidification system to remove latent load, while the vapour-compression and heat pipe heat exchanger meet the sensible load. Novelty comes as the heat pipe heat exchanger in the system operates efficiently without external power. Experimental set-up has been built by combining the rotary desiccant wheel, heat pipe heat exchanger with a compressive cooling system. Tests are carried out at typical operative ranges for air-conditioning applications, specifically for high hot and humid locations in Bangi, Malaysia. Acetone is used as refrigerant in the HPHE. Performance of HPHE are tested and proven to have direct impact on Coefficient of performance (COP). The results shows good performance of heat pipe heat exchanger efficiency with average efficiency and capacity of 0.65 and 2kw respectively. It is found that the hybrid system can achieve a higher energy performance in hot humid regions.

First building up the test bed of heat recovery unit which made use of Self-Exciting Mode Oscillating-Flow Heat Pipe heat exchanger, simulated the conventional wood drying chamber exhaust conditions, this paper compared and analyzed the different heat recovery efficiency of this heat exchanger under different operating modes. The results showed that: when the air flow and temperature at the hot end kept steady, the heat recovery efficiency increased as the relative humidity increasing; while the air flow and relative humidity at the hot end remained stable, the heat recovery efficiency decreased along with the temperature increasing; the hot end temperature reached the top on the dew point. The average heat recovery efficiency of Self-Exciting Mode Oscillating-Flow Heat Pipe heat exchanger was about 15%.
