Circulating water pump configuration system of concentrated cooling and heat supplying pipe network

Abstract

The invention discloses a circulating water pump configuration system of a concentrated cooling and heat supplying pipe network. The system is characterized in that the pipe network composed of a water supply pipe and a water return pipe is provided with a station pump and a user pump and / or a relay pump, the outlet of the station pump is connected with an inlet pipe of an energy station, an outlet pipe of the energy station is connected with the water supply pipe, an outlet of the user pump is connected with inlets of user ends, outlets of the user ends are connected with the water return pipe through a water discharging pipe, the relay pump is a pressurizing pump arranged on the remote water supply pipe, and the energy station and the user ends are provided with water temperature, water pressure and flow collecting and control devices. Compared with the prior art, the system has the advantages that output of the energy station is matched with requirements of users, heating power imbalance of excess pressure heads and systems of the heat pipe network is eliminated, negative efficiency energy consumption of the pipe network is reduced, heat conditions of the system are improved, operation efficiency is improved, the structure is simple and installation and operations are convenient to carry out.

Description

technical field [0001] The invention relates to the technical field of thermal pipe networks, in particular to a circulating water pump configuration system for centralized cooling / heating pipe networks of distributed energy stations. Background technique [0002] At present, in the centralized cooling system, the water passes through the refrigeration equipment at the energy station to reduce its temperature to about 5°C, and then driven by the circulating water pump, flows to each user through the pipeline, and absorbs the user's environment through the heat exchange equipment (such as fan coil unit). Heat, the water temperature rises to about 13°C, and then flows back to the energy station through the pipeline, completing a working cycle. The configuration of the central heating system is that the energy station is equipped with a set of (one or more parallel) circulating water pumps, several user terminals and a pipe network connecting the energy station with all users, ...

Problems solved by technology

But for the centralized cooling system, it is completely different. The circulating water is collected from various users to the energy station, and the temperature is lowered by the refrigeration equipment, but the circulating water pump converts the electric energy consumed by the pump itself into heat, which makes the circulating water in the pipe network warm up. Seriously affect the benefits of central cooling / heating enterprises
