Abstract
Metal organic framework (MOF) material is a new class of adsorbent material. This PhD research project set out to investigate the feasibility of an MOF based adsorption air conditioning system for automotive application. To achieve this, utilising a working pair with high refrigerant adsorption capacity and adsorber bed design with good heat and mass transfer performance was investigated. CPO-27Ni is the promising adsorbent. A finite element model was developed to evaluate the adsorption performance of adsorption bed. The rectangular finned tube adsorption bed was found to outperform the other designs.
A lab-scale test facility, based on a single bed refrigeration cycle containing one adsorber bed and one heat exchanger, used as both the evaporator and condenser, was constructed. The effects of various operating conditions on the system’s performance were experimentally investigated using this test facility.
A lumped-parameter mathematical simulation technique was developed to simulate the working process of the automotive adsorption air conditioning system based on a two-bed system capable of continuous cooling. The performance of the adsorption cooling system was investigated using this mathematical model. The results show that this adsorption air conditioning system can produce the required cooling capacity of 2.39kW, with specific cooling power (SCP) of 440W/kg and coefficient of performance (COP) of 0.456, when a desorption temperature of 130°C is obtained by hot oil heated by the engine’s exhaust gas.
