Air-conditioning system and method of operating the same

An air conditioning system comprising:

• a desiccant for adsorbing moisture from process air;
• and a heat pump, including a compressor, that operates by using process air as a low-temperature heat source and regeneration air as a high-temperature heat source so as to supply heat to regeneration air for regenerating said desiccant;
• wherein post-desiccant process air that has passed through said desiccant exchanges heat in a first sensible heat exchanger with regeneration air that has not yet flowed into a high-temperature heat source heat exchanger of said heat pump;
• and regeneration air that passed through said first sensible heat exchanger but has not yet entered said high temperature heat source heat exchanger exchanges heat in a second sensible heat exchanger with post-desiccant regeneration air;
• and heat transfer processes in said first sensible heat exchanger are made adjustable.

• and a heat pump, including a compressor, that operates by using process air as a low-temperature heat source and regeneration air as a high-temperature heat source so as to supply heat to regeneration air for desiccant regeneration;
• wherein paths of process air and regeneration air that pass through said desiccant are divided into a first zone for dehumidifying process air and a second zone for regenerating said desiccant using regeneration air so that said desiccant repeatedly shifts its position between said first zone and said second zone, and said heat pump is comprised by at least a compressor, a low-temperature heat source heat exchanger and a high-temperature heat source heat exchanger, and said path of process air is routed sequentially from an inlet for said process air, through said desiccant in said first zone, a first sensible heat exchanger, and said low-temperature heat source heat exchanger to arrive at an outlet for process air, and said path of regeneration air is routed sequentially from an inlet for said regeneration air, through said first sensible heat exchanger, a second sensible heat exchanger, said high temperature heat source heat exchanger, said desiccant in said second zone, and said second sensible heat exchanger to arrive at an outlet for regeneration air, and process air exchanges heat with regeneration air in said first sensible heat exchanger, regeneration air exchanges heat with regeneration air in said second sensible heat exchanger, and heat transfer processes in said first sensible heat exchanger are made adjustable.
