Digital air conditioner water system and digital air conditioner water evaluation method

Abstract

The invention belongs to the technical field of air conditioner ventilation energy conservation, and particularly provides a digital air conditioner water system and a digital air conditioner water evaluation method. The digital air conditioner water system comprises a water chilling unit, a chilled water pump and a pipeline, and further comprises an energy regulating valve, a temperature sensor,a flow sensor, a cloud platform server and a monitoring platform. Information data of flow, water supply temperature, water return temperature, temperature difference and cooling capacity of the pipeline and information data of water supply temperature, water return temperature and total flow of chilled water are analyzed, operation data are monitored and accumulated in real time, a database is upgraded, operation curves of all devices are generated, and a preset evaluation strategy is used in combination so that online evaluation and condition diagnosis can be carried out on the running stateof an air conditioner chilled water system. Digitization, precision, networking and cloud of the air conditioner chilled water system are realized; a foundation is laid for a digital air conditioningsystem; and the digital air conditioner water system and the digital air conditioner water evaluation method can be popularized, referred and applied in the design of a central air conditioner chilled water system.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning ventilation and energy saving, and in particular relates to a digital air-conditioning water system and an evaluation method. Background technique [0002] At present, the automation degree of the centralized air-conditioning chilled water system is generally low, mainly the traditional constant flow operation mode, and the high-power water pump is started and stopped under the power frequency state all the year round, which not only increases the incidence of equipment failure, but also greatly reduces the use of equipment life, and lead to higher energy consumption of the system operation. Due to the characteristics of the air-conditioning system, the system operates under partial load most of the time, coupled with problems such as equipment selection deviations, the circulating water pump often has a large margin, and the air-conditioning water system generally operates with a large f...
