Abstract

The invention discloses a two-network water supply and return temperature control method aiming at solar radiation. According to the method, the real-time environment temperature of a building heat load and the solar radiation are integrated into the integral outdoor temperature. The method concretely comprises the following steps that each factor in an integral comprehensive outdoor temperature calculation formula of a building is determined; integral outdoor temperatures corresponding to four wall bodies including the east wall body, the south wall body, the west wall body and the north wall body are calculated; the integral comprehensive outdoor temperature of the building is calculated; factors in a simplified two-network water supply and return temperature calculation formula are calculated; the two-network water supply and return temperature is determined. The method provided by the invention has the advantages that the two-network water supply and return temperature can be accurately and reliably determined, and the excessive heat supply is avoided.

Description

technical field [0001] The invention belongs to the technical field of central heating, and in particular relates to a method for controlling the temperature of secondary network supply and return water aimed at solar radiation. Background technique [0002] With the rapid development of society, the increase of demand for heat, and the requirements of energy conservation and emission reduction, my country's central heating industry has developed rapidly. Central heating technology has become the mainstream technology of winter heating and plays an important role in winter heating due to its advantages of high energy utilization rate, improved environmental sanitation, easy realization of scientific management, and improved heating quality. [0003] Central heating technology fundamentally adjusts the heating load according to changes in environmental conditions, so as to keep the heating building at a set and comfortable temperature and reduce unnecessary heat loss. It can...
