  • A novel summer Air Conditioning System
    Energy Conversion and Management, 2002
    Co-Authors: Moh’d A. Al-nimr, Bassam A. Abu-nabah, Maryam Naji
    Abstract:

    A novel summer Air Conditioning System is proposed. The proposed System modifies the work of the classical evaporative summer Air Conditioning System. The performance of the proposed System is investigated quantitatively, and a comparison between the performance of the classical and the modified Systems is conducted. It is found that the modified System improves the performance of the classical one by about 100%.

  • Effect of working fluids on the performance of a novel summer Air Conditioning System
    International Communications in Heat and Mass Transfer, 2001
    Co-Authors: Moh’d A. Al-nimr, M.r. Daqqaq, M. A. Hader
    Abstract:

    The performance of the classical evaporative summer AirConditioning System for different working fluids is studied. Also a modified summer Air Conditioning System is proposed. The performance of the proposed System for different working fluids is investigated quantitavely and the performance of both Systems for different working fluids is compared. It is found that changing the working fluids of the classical evaporative System influences the efficiency especially for Argon by about 8%, whereas the change of working fluids for the modified System improves the efficiency slightly.

  • experimental investigation on the photovoltaic thermal solar heat pump Air Conditioning System on water heating mode
    Experimental Thermal and Fluid Science, 2010
    Co-Authors: Gui Yin Fang, Hainan Hu
    Abstract:

    Abstract An experimental study on operation performance of photovoltaic–thermal solar heat pump AirConditioning System was conducted in this paper. The experimental System of photovoltaic–thermal solar heat pump AirConditioning System was set up. The performance parameters such as the evaporation pressure, the condensation pressure and the coefficient of performance (COP) of heat pump AirConditioning System, the water temperature and receiving heat capacity in water heater, the photovoltaic (PV) module temperature and the photovoltaic efficiency were investigated. The experimental results show that the mean photovoltaic efficiency of photovoltaic–thermal (PV/T) solar heat pump AirConditioning System reaches 10.4%, and can improve 23.8% in comparison with that of the conventional photovoltaic module, the mean COP of heat pump AirConditioning System may attain 2.88 and the water temperature in water heater can increase to 42 °C. These results indicate that the photovoltaic–thermal solar heat pump AirConditioning System has better performances and can stably work.

  • Thermoelectric AirConditioning System: Building Applications and Enhancement Techniques
    International Journal of Air-Conditioning and Refrigeration, 2019
    Co-Authors: Aklilu Tesfamichael Baheta, Kar Kin Looi, Ahmed Nurye Oumer, Khairul Habib
    Abstract:

    The high reliability, the absence of working fluid and auxiliary pipes in the thermoelectric cooling application have attracted the attention of researchers in the last two decades. However, the use of thermoelectric AirConditioning System for building application has not been entirely explored due to its low coefficient of performance (COP) compared to the conventional Air Conditioning System. To overcome this primary limitation, different COP enhancement techniques of thermoelectric for Air Conditioning System building application are made available. This paper provides the recent development of thermoelectric Air Conditioning System in building applications, such as thermoelectric radiant panel ceiling, thermoelectric Air duct System and thermoelectric cooling facades. It also provides the different strategies to enhance its performance in order to fit this technology in real building applications such as the integration of water-cooling System, phase change materials, evaporator cooling System and nanofluid micro-channel heat sinks. Lastly, the challenges of thermoelectric AirConditioning Systems and future research directions are discussed.
