Problems solved by technology

Large temperature difference transmission and distribution is currently the main means to reduce the consumption of air-conditioning water delivery pumps. However, in the system of direct air-conditioning water supply terminal, the parameters of supply and return water of energy stations are often required to be consistent with the energy consumption parameters of end users, which limits the transmission and distribution of large temperature difference. matching application

Abstract

The invention relates to the technical field of air conditioner control, in particular to a large-temperature-difference air conditioner water transmission and distribution system based on a water mixing pump and a control method thereof. The system comprises a control unit, a water mixing pump, a regulating valve, a water mixing thermometer and a water return thermometer; a water return pipe is communicated with a user water inlet pipe through a water mixing pipe; the water mixing pump is arranged on the water mixing pipe, and the water mixing thermometer and the regulating valve are sequentially arranged between an outlet of the water mixing pump and a water inlet of an end user; the return water thermometer is arranged between a water outlet of the end user and an inlet of the water mixing pump; data output ends of the water mixing thermometer and the return water thermometer are connected with a data input end of the control unit; and a control signal output end of the control unit is connected with control signal input ends of the water mixing pump and the regulating valve. The relation that energy station water supply and return parameters in an air conditioner water system of an energy station direct supply tail end need to be consistent with user tail end energy consumption parameters is decoupled, the water supply and return temperature difference is increased, the system circulating water amount is reduced, conveying pump consumption is effectively reduced, and a temperature value is kept stable.

Description

technical field [0001] The invention relates to the technical field of air-conditioning control, in particular to an air-conditioning water transmission and distribution system with a large temperature difference based on a water mixing pump and a control method thereof. Background technique [0002] Compared with independent central air-conditioning systems for individual buildings, the use of centralized cooling and heating systems can reduce the total installed capacity of units by about 20% to 30%, corresponding to the initial investment in power transformation and distribution systems, refrigeration rooms, power transformation and distribution, etc. Equipment and the area of ​​the computer room are correspondingly reduced by more than 20% to 50%, reducing system construction investment. Improve energy utilization. Centralized management of cold and heat source equipment can realize cascade utilization of energy. Large-scale advanced and efficient devices are used to ach...
