Energy regulation method for air-conditioning water system

Abstract

The invention discloses an energy regulation method of an air-conditioning water system, comprising: obtaining the temperature T of the water inlet in the air-conditioning water system 1 , Outlet water temperature T 2 , user set temperature T set , the first preset threshold a and the second preset threshold b; determine the temperature T set by the user set and outlet water temperature T 2 Whether the absolute value of the temperature difference is greater than 2a; determine the temperature T set by the user set and outlet water temperature T 2 Whether the absolute value of the temperature difference is between 2b and 2a; determine the temperature T set by the user set and outlet water temperature T 2 Whether the absolute value of the temperature difference is between 0 and 2b; determine the outlet water temperature T 2 Is it greater than the user's set temperature T set , if yes, enter step S6, if not, repeat the above steps S1‑S5; stop. The present invention can achieve precise control of the outlet water temperature when the fluctuation of the water flow is small; when the temperature is close to the operating temperature, the start-up amount of the system in the unit can be reduced to achieve the purpose of energy saving.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning water system regulation, and in particular relates to an energy regulation method of an air-conditioning water system. Background technique [0002] With the continuous progress of urbanization and industrialization, the proportion of building energy consumption in the total energy consumption of the society is increasing. At present, the energy consumption of buildings has accounted for 33% of the total energy consumption of the society, and 36% of it comes from central air-conditioning water. System power consumption. Under the current situation of increasing energy shortage, the energy saving of building central air-conditioning system has become a hot spot of widespread concern, and the central air-conditioning water system is the main energy-consuming part of the central air-conditioning system, and it has important social and economic significance to take energy-saving measures for ...

AI Technical Summary

Problems solved by technology

With the change of environmental parameters and the flow of people in the building, the operating load and operating environment of the air-conditioning water system change dynamically, but the operating parameters of each equipment in the conventional central air-conditioning water system cannot be properly adjusted with the dynamic changes in the load and outdoor environment. Maximize the operating efficiency of each equipment in the system under a certain cooling load

The operating parameters of each equipment in the central air-conditioning water system cannot be properly adjusted with the load change, so that the equipment of the system cannot operate under the optimal working condition, resulting in an increase in energy consumption of the air-conditioning water system

[0004] In the existing air-conditioning water system, the frequent start-stop of the unit and the excessive fluctuation of water temperature often occur when the air-conditioning equipment is controlled, which seriously affects the use of users and the safe operation of the unit

In actual control, mandatory measures are often used to limit the water temperature, which fails to achieve good temperature control
