Intelligent heat supply energy saving calorimeter

Abstract

The invention relates to an intelligent heat supply energy saving calorimeter, which comprises a shell, a power supply, a singlechip, a flow sensor, a relay or a photocoupler, a magnetic valve or a flow valve, a flow valve drive circuit, an electronic reader, a man-machine conversation display screen or a display, a keypad, a digital thermal sensor or an analog digital conversion circuit and a simulation temperature sensor, not only can count flow rate, heat quantity and charge, but also can automatically control heating and non-heating according to the activity regularity of people, can automatically control the highest heating temperature during heating, prevents the overtemperature of a room during heating, saves the heating power source, keeps comfortable human environment, can automatically control the keeping warm temperature during non-heating, prevents the jellying and frost cracking of the heating pipe network, and simultaneously meets the heating and non-heating requirement in particular cases.

Description

Technical field [0001] The invention relates to the fields of automatic control, heat supply and fluid metering. Background technique [0002] In the heating season every year, people have to invest a lot of financial and material resources to solve the heating problem. The energy used for heating is mainly non-renewable energy such as coal, oil, and natural gas, and the consumption is large. In the case of energy shortage and rising prices, heating The cost is getting higher and higher. At the same time, coal, oil, and natural gas produce a large amount of harmful substances such as dust, carbon dioxide, and sulfur dioxide during the combustion process, resulting in air pollution and a large amount of greenhouse gas emissions, which leads to inhalable air in northern cities during the heating season. Particles seriously exceeded the standard, and the air quality dropped significantly. [0003] In the heating process, whether it is an office building, office building, dormi...

Problems solved by technology

[0009] In order to overcome the shortcomings of the current heating flow meter or heat meter in the heating process regardless of whether there are people in the room or whether the heating is useful or not, and keep heating continuously 24 hours a day, resulting in a large waste of energy, air pollution and large emissions of greenhouse gases, this paper The invention provides an intelligent energy-saving metering device for heating. The metering device can not only perform flow metering, calorie metering and billing for heating, but also can automatically control when to provide heating and when not to provide heating according to the rules of personnel activities; it can automatically control heating The maximum heating temperature during the heating period can prevent the indoor temperature from being too high during the heating period, which not only saves heating energy, but also maintains a comfortable living environment; it can automatically control the heating temperature during the non-heating period to prevent the indoor temperature from being too low during the non-heating period, and prevent the heating pipe network Freezing and cracking; meeting heating and non-heating needs in special cases at the same time
