Abstract

The invention provides a combined heat and power generation system. A data connection is established between a programmable controller of the system and a heat meter and a regulating valve, and the programmable controller is used for carrying out automatic controlling on the combined heat and power generation system. Heat usage data of a user are sent to the programmable controller through the heat meter. Heat bought by the user is compared with the currently used heat by the programmable controller, if the heat is used up, the programmable controller controls the regulating valve to close completely. According to the combined heat and power generation system, a novel heating system capable of carrying out the heat control is achieved, the heat is bought by the user-self, once the heat is used up, heating is automatically stopped, so that the energy saving, environmentally friendly and energy conserving purpose is 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...
