Intelligent heat-exchange circulating system capable of realizing heating by using secondary pump

Abstract

The invention discloses an intelligent heat-exchange circulating system capable of realizing heating by using a secondary pump. The system mainly comprises plate heat exchangers, a variable-frequency water replenishing pump, circulating pumps, a main control cabinet and a plurality of heating sub-regions, wherein a secondary water supply pipe and a secondary water return pipe which are connected with the plate heat exchangers are connected through a check valve II to form circulation, a temperature control valve is mounted on a primary water supply pipe, the secondary water supply pipe is connected with water distribution branch pipes and the plurality of heating sub-regions respectively, the plurality of heating sub-regions are connected with water return branch pipes, and the water return branch pipes and the secondary water return pipe are connected to form secondary circulation respectively. The system has the benefits as follows: with the adoption of the circulating system capable of using the secondary pump, the heating service range is expanded, the investment is saved, occupied land is reduced, the efficient heat exchange effect is guaranteed, energy conservation and emission reduction are facilitated, meanwhile, the system is complete in system configuration and high in automation degree, unattended remote wireless monitoring and management can be realized conveniently, and the reliability of safe operation is improved.

Description

technical field [0001] The invention relates to the technical field of heating, in particular to an intelligent heat exchange cycle system using a secondary pump for heating. Background technique [0002] With the development of urbanization construction and livable environment, buildings with different functions will be interspersed. The heating systems required by buildings with different functions are different in terms of heating height, heating time, and heating temperature. If heat exchange stations and heat exchange equipment are set up separately according to different heating systems, it will inevitably lead to a large one-time investment and occupy Large land, high energy consumption, inconvenient management and maintenance, etc. Contents of the invention [0003] The object of the present invention is to provide an economical, resource-saving and efficient intelligent heat exchange cycle system that utilizes a secondary pump for heating. [0004] The technical...
