The common function of air-conditioning comprises refrigeration, heat, dehumidify and the mode of operation such as ventilation, the air-conditioning system of multiple air-conditioner host operationally, when a usual main frame is opened and is loaded on full operating mode, open next main frame again, but although this mode can ensure that air-conditioning system there will not be energy waste, but because the main frame of whole system is opened by platform, air-conditioning is slow for the regulating action of room air, such as need long time just can reach preset temperature or appropriateness, therefore indoor comfort is poor.
Energy consumption power needed for calculations of air conditioner system can realize in the following manner: the mode of operation determining air-conditioning system, the default energy consumption model of air-conditioning system under acquisition relevant work pattern; According to the energy consumption power needed for default energy consumption model calculations of air conditioner system.Determine that namely the mode of operation of air-conditioning system also determines that the mode of operation of air-conditioning is refrigeration mode, heating mode, dehumidification mode or air vent mode, under acquisition relevant work pattern, namely the default energy consumption model of air-conditioning system also obtains energy consumption for cooling model according to the mode of operation of the air-conditioning system determined, or heat energy consumption model, or dehumidifying energy consumption model, or ventilation energy consumption model, according to the energy consumption power needed for the energy consumption model calculations of air conditioner system work preset got.The default energy consumption model of air-conditioning system is not limited to concrete form, can set according to actual conditions, also can adjust according to various factors.
Such as, under acquisition relevant work pattern, the default energy consumption model of air-conditioning system is the default energy consumption model of air-conditioning system under acquisition refrigeration mode, energy consumption power needed for default energy consumption model calculations of air conditioner system can be the refrigerating capacity needed for energy consumption for cooling model calculations of air conditioner system according to presetting, wherein, refrigerating capacity refer to air-conditioning when cooling operation in the unit interval from the energy of confined space removing, the refrigerating capacity needed for calculations of air conditioner system comprises: obtain air-conditioning system energy consumption for cooling model in cooling mode; Detect the chilled-water flow of air-conditioning system; Detect the water capacity of the operational system of air-conditioning system; Detect the chilled water backwater rate of temperature fall of air-conditioning system; Detect the mean value of the air-conditioning system online main frame Inlet and outlet water temperature difference; And the refrigerating capacity needed for the mean value calculation air-conditioning system of the water capacity of the chilled-water flow of default energy consumption model, air-conditioning system, the operational system of air-conditioning system, the chilled water backwater rate of temperature fall of air-conditioning and the air-conditioning system online main frame Inlet and outlet water temperature difference.The chilled water circulatory system of air-conditioning system is primarily of refrigerating water pump, indoor fan and chilled water pipeline composition, the cryogenic freezing water flowed out from main frame evaporimeter sends into chilled water pipeline by refrigerating water pump pressurization, enter indoor and carry out heat exchange, take away the heat in room, finally get back to main frame evaporimeter, indoor fan is used for air to blow over chilled water pipeline, reduce air themperature, heat exchange in accelerating chamber.Wherein, the input of the energy consumption for cooling model of air-conditioning system comprises: the chilled-water flow of air-conditioning system; The water capacity of the operational system of air-conditioning system; The chilled water backwater rate of temperature fall of air-conditioning system; The mean value of the air-conditioning system online main frame Inlet and outlet water temperature difference.Wherein, the chilled-water flow G of air-conditioning system refers to that reference units is m for carrying out the flow of the unit interval of the water freezed in air-conditioning 3/ h, the water capacity M of the operational system of air-conditioning system refer to that the total amount of the operational system water of air-conditioning system, reference units are m 3the chilled water backwater rate of temperature fall Δ T of air-conditioning system refers to that the chilled water of air-conditioning system flows out and the rate temperature change flowed back to, reference units is DEG C/min, the mean value Δ t of the air-conditioning system online main frame Inlet and outlet water temperature difference refers to the mean temperature difference of the online main frame water inlet of air-conditioning system and water outlet, and reference units is DEG C.Above-mentioned four state parameters detected are input in default energy consumption for cooling model, calculate the energy consumption power needed for air-conditioning system.When detecting the mean value of the chilled-water flow of air-conditioning system, the water capacity of the operational system of air-conditioning system, the chilled water backwater rate of temperature fall of air-conditioning system and the air-conditioning system online main frame Inlet and outlet water temperature difference, can be detected every Preset Time by sensor, such as, at interval of 10 seconds or 30 seconds, the mean value of the water capacity of the chilled-water flow of air-conditioning system, the operational system of air-conditioning system, the chilled water backwater rate of temperature fall of air-conditioning system and the air-conditioning system online main frame Inlet and outlet water temperature difference is detected.

In operation of air conditioner process, the energy consumption power needed for air-conditioning system is recalculated every Preset Time, such as again detect the relevant detected parameters of air-conditioning system refrigeration every 10 seconds or 30 seconds, heat relevant detected parameters, the detected parameters that dehumidifying is relevant, the detected parameters etc. that ventilation is relevant, recalculate the energy consumption power that air-conditioning system needs, obtain the adjusted value of energy consumption power, redefine the operation quantity of air-conditioner host according to the adjusted value of energy consumption power, the operation quantity of operation quantity to air-conditioner host according to the air-conditioner host redefined adjusts.
