Description
Technical Field
The invention relates to the technical field of Internet of things, in particular to a building distributed air source centralized control system and method.
Background
At present, air source equipment is mostly adopted to meet the requirements of heating in winter, cooling in summer and hot water for life in cities. The air source equipment mainly comprises large-scale air source equipment, medium-scale air source equipment and small-scale air source equipment.
The large-scale air source equipment is installed in a fixed place, generally in an underground structure, and corresponding heat utilization requirements are provided for all required parts in a building through a water line pipeline in a mode that a plurality of large-scale equipment are connected in parallel. The heat-conducting medium is water generally, and a special bearing facility is needed due to the large volume and weight of the main machine, and a special facility is needed to be equipped for shock absorption and noise reduction due to the huge noise and vibration generated during the operation of the equipment. And a split type outdoor heat dissipation tower is adopted for heat dissipation in the cooling process. The single machine power is more than 120 KW.
The medium-sized air source equipment is mostly installed in fixed places, such as underground structures or outdoor special areas, and corresponding heat utilization requirements are provided for all required parts in a building through a water line pipeline in a mode of connecting a plurality of equipment in parallel. The medium-sized air source equipment does not have the capacity of producing domestic hot water, and needs to be equipped with independent domestic hot water equipment. The heat-conducting medium is water generally, and special bearing facilities are needed due to the large volume and weight of the main machine, and special facilities are needed to be equipped for shock absorption and noise reduction due to the huge noise and vibration generated during the operation of the equipment. The placement location is generally at the top of the building or at a concealed location on the ground. And the cooling adopts an outdoor heat dissipation tower which is combined by a split type and an integrated type to dissipate heat. The single machine power is about 50-100 KW.
The small air source equipment is arranged outside the fixed area, and corresponding heat utilization requirements are provided for all required parts in a building through a water line pipeline in a single direct supply or multiple equipment parallel connection mode. Generally, the small air source equipment does not have the capacity of generating domestic hot water, and needs to be provided with independent small water storage equipment. Special outdoor platform structure bearing facilities are needed, and due to certain noise and vibration generated during the operation of the equipment, the arrangement position is generally in the top layer of a building or an air conditioning room structure on the outer facade of the building. And the cooling adopts an integrated heat dissipation tower for heat dissipation. The single machine power is below 50 KW.
Currently, the various air source devices described above include host temperature control; controlling the running frequency; controlling the temperature of the effluent; and controlling basic equipment such as storage water temperature and the like. But the device does not have a control basis, cannot sense the room temperature or the hot spot condition, and has no way to automatically adjust.
And according to the building energy-saving standard established by the current residential and construction departments in China, the air source is adopted to calculate the cold and heat loads of the unit area to be between 80 and 150W. Because the building heat utilization generally adopts large and medium-sized air source equipment, special sites and facilities are needed, the building heat utilization is generally arranged in underground structures, roofs and places far away from the buildings, and heat exchange is needed through a main pipeline due to the influence of the sites and the occupied area of the equipment. The main pipeline and the branch pipelines can absorb the heat of the medium in the transmission process, and the main pipeline and the branch pipelines cannot completely achieve ideal effects due to the construction cost constraint heat preservation measures. The heat generated by the equipment can lose 10% -20% of the heat at the outlet in each type of pipeline, and the heat loss can be further increased along with the extension of the heat consumption distance, so that the operation cost is increased.
