Description
技术领域technical field
本实用新型涉及中央空调系统节能领域，尤其涉及一种组合式空调箱的全工况自适应控制装置。The utility model relates to the energy-saving field of a central air-conditioning system, in particular to an adaptive control device for all working conditions of a combined air-conditioning box.
背景技术Background technique
节能已经成为一个全球性话题，而空调节能作为其中举足轻重的一个项目，牵动着许多国家的神经。近几年，随着能源问题的日趋紧张，各国纷纷看到空调节能的重要性，采取了一系列措施鼓励节能产品入市。在取得能源节约的同时，推动了空调行业技术的升级换代以及节能控制装置的创新和应用，得到了社会广泛的支持。Energy saving has become a global topic, and air-conditioning energy saving, as one of the most important projects, affects the nerves of many countries. In recent years, with the increasingly tense energy issues, countries have realized the importance of air-conditioning energy saving, and adopted a series of measures to encourage energy-saving products to enter the market. While achieving energy conservation, it has promoted the upgrading of air-conditioning industry technology and the innovation and application of energy-saving control devices, and has received extensive support from the society.
为使空调系统在全年任意时段都能保证建筑内部的冷量需求，在选用空调系统时都是按当地最热天气所需的制冷需求的115％左右来选取机型的。由于在中央空调的运行过程中，空调末端、制冷主机、水泵、冷却塔等都没有任何负荷随动能力，从而导致空调长期在较高工况下运行，造成大量的能源浪费。In order to ensure that the air-conditioning system can guarantee the cooling demand inside the building at any time of the year, the air-conditioning system is selected according to about 115% of the cooling demand required by the hottest local weather. During the operation of the central air conditioner, the air conditioner terminal, refrigeration main unit, water pump, cooling tower, etc. do not have any load follow-up capability, which leads to the long-term operation of the air conditioner under high working conditions, resulting in a lot of energy waste.
在中央空调的运行过程中，现有的全年运行工况的空调系统运行的工况较多，各工况间的转换通常采用人工的方式进行；当空调对温湿度的控制范围有较高的要求时，控制不当会引起冷热源相互抵消的情况发生；当建筑内人员的变动很大时，传统的控制方式很难合理的调节新风量，满足人体卫生的需求；在传统的控制方法中，对新风的合理利用还存在很大的改善空间。During the operation of the central air-conditioning system, the existing air-conditioning system with annual operating conditions operates under many operating conditions, and the conversion between various operating conditions is usually carried out manually; when the air conditioner has a high control range for temperature and humidity When the requirements are met, improper control will cause the cold and heat sources to offset each other; when the personnel in the building changes greatly, it is difficult for the traditional control method to reasonably adjust the fresh air volume to meet the needs of human hygiene; in the traditional control method Among them, there is still a lot of room for improvement in the rational use of fresh air.
在空调系统的节能运行中，是基于对空调系统全年运行工况的节能分析和运行控制，根据室内的控制参数和室外的气象参数进行分区，不同的分区工况采用不同的空气处理流程，在空气处理过程中充分考虑利用新风，调节新回风的比例等方法，既对温湿度进行了良好的控制，又尽可能减少了冷热源的使用。控制系统还充分考虑空调系统允许的运行参数的波动范围，这样既满足了空调要求又节约了能源。因为不论新风是定量或可变量，如果室外空气状态点在某个区，混风状态点一般也在某个区，因而可以肯定处理方案，只要处理到送风状态附近，而以室内状态点的反馈作为标准进行细调节，所以组合式空调箱采用全工况分区的自适应控制系统，能实现最大化节能。In the energy-saving operation of the air-conditioning system, it is based on the energy-saving analysis and operation control of the annual operating conditions of the air-conditioning system, and partitions are made according to indoor control parameters and outdoor meteorological parameters. Different partitions use different air treatment processes. In the process of air treatment, fully consider the use of fresh air and adjust the proportion of fresh return air, etc., which not only controls the temperature and humidity well, but also reduces the use of cold and heat sources as much as possible. The control system also fully considers the fluctuation range of the operating parameters allowed by the air-conditioning system, which not only meets the air-conditioning requirements but also saves energy. Because no matter whether the fresh air is quantitative or variable, if the outdoor air state point is in a certain area, the mixed air state point is generally also in a certain area, so the treatment plan can be determined, as long as the treatment is near the air supply state, and the indoor state point Feedback is used as a standard for fine adjustment, so the combined air conditioning box adopts an adaptive control system for all working conditions and partitions, which can maximize energy saving.
