Calculation on Energy Saving Potential of a New Dry-type Air-conditioning System
Temperature and humidity independent control can be made by a new dry-type air-conditioning system,the combination of silica gel rotor and heat pump.Heat pump cycle can simultaneously cool the process air and heat the regeneration air,so it can cancel each other out in the cold and heat energy consumption within the system.This novel form of system not only solves the regeneration energy issues fundamentally but also avoids energy waste by reheating in conventional cooling dehumidification air-conditioning system.Based on the establishment of the component model,MATLAB program has been compiled to simulate the combined system running at nominal operating conditions and calculate the performance parameters and energy efficiency.Comparison of the energy efficiency was made of this dry-type air-conditioning system with ones of other regeneration desiccant wheel air conditioning system and conventional cooling dehumidification air-conditioning system,the results of which show that the new dry-type system provided regeneration energy,overcomes the restriction from climate,region and using conditions of other regeneration.Moreover,compared with conventional re-heat air-conditioning system,its energy saving is up to 35.1% and the energy efficiency is increased by 38.1%.
