Technical field
The utility model relates to the technical field of the aircondition in civilian and industrial project, particularly relates to a kind of aircondition of processing the hot humidity load of air and preparing cold water or hot water simultaneously.
Background technology
At present, energy-saving and emission-reduction, building a resource-conserving society becomes when last very important work, building energy consumption accounts for 30% left and right of whole society's energy consumption, wherein air conditioning energy consumption accounts for again the 40-60% of building total energy consumption, therefore, reduce central air conditioner system energy consumption and become an important directions of China's energy-saving and emission-reduction.
Current central air conditioner system, refrigeration (heating) unit and air-conditioning unit are the independent equipment arranging.Above-mentioned air-conditioning system framework is comparatively ripe, but aspect energy saving of system, there are following three shortcomings that are difficult to overcome: 1, refrigeration (heating) unit, to needing many times Pipeline transports complicated, long distance to connect between end air-conditioning unit, needs to consume very large transmission & distribution energy consumption (accounting for the 20-35% of air conditioning energy consumption) always; 2, concentrated refrigeration (heating) unit and concentrated pipeline transport system, the adjusting function of its sub-load is difficult to well adapt to the demand operating mode of partial air conditioning (heating), causes air-conditioning equipment (Cooling and Heat Source equipment, circulating pump etc.) fallback and energy waste; 3, concentrate corresponding multiple air conditioning zonings, cold (heat) source, also cause the assignment of traffic of different air conditioning zonings to regulate difficulty, this be because cold (heat) water yield that each air conditioning zoning needs not only in design point difference, not identical in the time of operation at part load, and be real-time change yet; 4, control system need to be managed and be coordinated refrigeration plant, heating equipment, circulating pump, end-equipment (new blower fan group+fan coil, or combined air conditioning box) etc., and Control System Design, construction and management are used all very complicated.
