A Combined Heat and Power System with Regulating Valves Adapting to Changes

Abstract

The invention provides a combined heat and power generation system with regulating valves adapting to changes. According to the combined heat and power generation system with the regulating valves adapting to the changes, the first regulating valve is arranged on a hot water supply pipe to regulate hot water entering into a heat exchanger; the second regulating valve is arranged on a water inlet pipeline of a radiator, data connection is conducted between a programmable logic controller and the first regulating valve as well as between the programmable logic controller and the second regulating value, and when the opening degree of the second regulating valve changes, the opening degree of the first regulating valve changes correspondingly to enable the hot water input into the heat exchanger to change correspondingly. According to the combined heat and power generation system with the regulating valves adapting to the changes, the heat exchange efficiency is maximized through the corresponding changes of the regulating valves, the energy is saved, and the purposes of protecting environment and saving energy are achieved.

Description

[0001] This application is a divisional application for the patent application whose original application number is 2014101475402 and the invention name is an intelligent cogeneration system. technical field [0002] The invention belongs to the field of heat exchangers, in particular to a radiator in the field of combined heat and power generation, and belongs to the field of F28 heat exchangers and the field of F24D heat supply. Background technique [0003] Among the radiators, finned tube radiators are widely used at present. The heat dissipation area can be enlarged and the heat exchange effect can be enhanced through the fins. However, the radiator type of the finned tubes and the setting of the finned tube parameters all affect the cooling effect. Good or bad, and in the current situation of energy crisis, there is an urgent need to save energy and meet the sustainable development of society. Maximize thermal efficiency to save energy and achieve the purpose of enviro...
