技术领域Technical field
本发明涉及冷水机组选型技术领域，特别涉及一种冷水机组选型方法和装置。The invention relates to the technical field of chiller selection, in particular to a chiller selection method and device.
背景技术Background technique
目前，中央空调冷水机组的参数多采用样册的形式介绍给用户，样册给定了一定参数下冷水机组的制冷量、运行功率、重量、尺寸等参数。实际使用中，由于特殊场所、特殊用途等需求，用户工况会与样册标准工况有一定偏差，这时样册上的参数就不能准确反映机组在用户工况的实际表现。这种情况下就需要对机组进行重新设计，重新计算各项参数给到用户，增加很多中间的沟通环节，响应速度很慢。At present, the parameters of the central air-conditioning chiller are introduced to the user in the form of a sample book. The sample book gives parameters such as cooling capacity, operating power, weight and size of the chiller under certain parameters. In actual use, due to the special site, special use and other requirements, the user's working conditions will have a certain deviation from the standard working conditions of the sample book. At this time, the parameters on the sample book cannot accurately reflect the actual performance of the unit in the user's working condition. In this case, the unit needs to be redesigned, the parameters are recalculated to the user, and many intermediate communication links are added, and the response speed is very slow.
虽然，目前可通过提供变工况表，对非标准工况进行修正，这种方式虽然能够区别于标准工况与非标准工况下机组的制冷量与运行功率偏差，但无法计算制冷量不变的情况下工况偏移之后的性能，且不够准确。或者，可使用Excel表格编辑简易公式进行计算，但这种方式需要根据经验更改相关参数进行计算，不适合没有经验的用户使用。或者，通过编译工具做出的选型软件进行选型，但是仍然对非标工况进行选择，适用范围有很大的局限性。Although it is currently possible to correct non-standard conditions by providing a variable operating condition table, this method can distinguish between the cooling capacity and the operating power deviation of the unit under standard and non-standard conditions, but cannot calculate the cooling capacity. Performance after shifting conditions, and not accurate enough. Alternatively, Excel spreadsheets can be used to edit simple formulas for calculations, but this method requires calculations based on empirical changes to the parameters and is not suitable for inexperienced users. Or, the selection software made by the compiler tool is selected, but the selection of the non-standard condition is still selected, and the scope of application has great limitations.
