Return water temperature determining method for centralized heating system

Abstract

The method for determining temperature of return water of central heating system is characterized by that according to the circulating water flow of heating system and outdoor maximum air temperatureand minimum air temperature the "return water temperature-circulating water flow-outdoor temperature" curve diagram can be drawn, then according to indoor and outdoor temperatures said curve diagram can be looked over to determine the temperature of return water of said centre heating system, said invention also provides the principle and method for drawing said curve diagram, and can attain the goal of ensuring heating temperature, saving energy, reducing consumption and reducing pollution.

Description

Technical field: [0001] The invention relates to the technical field of return water temperature control of a central heating system, in particular to a method for determining the return water temperature of a central heating system. Background technique: [0002] At present, there is no practical and effective method to guide the adjustment of water supply and return water temperature in small central heating systems. Due to the influence of factors such as equipment conditions, operation mode, management level and personnel quality, the use of calculation formulas or instrument control methods for heating systems It is difficult to adjust the temperature. Over the years, most of them have adjusted the temperature based on the feeling and experience of outdoor weather changes, that is, "seeing the sky and burning the fire", which fails to achieve the purpose of scientific energy saving and pollution reduction. Invention content: [0003] The purpose of the present inventi...
