SELF POWER-GENERATING HEAT METER USING THERMOELECTRIC ELEMENT AND METHOD FOR MEASURING AMOUNT OF HEAT

摘要

The present invention relates to a heat meter for measuring the amount of cooling or heating energy supplied through a pipe. The present invention provides a self power-generating heat meter using a thermoelectric element, wherein the heat meter for measuring an amount of cooling or heating energy supplied through a pipe comprises: a flow measurement unit for measuring the amount of a fluid supplied through the pipe; a temperature measurement unit for measuring a temperature difference between a supplying-side pipe and a collecting-side pipe; a heat amount calculation unit for calculating the an amount of the supplied energy by using the measured flow value and the temperature difference measurement value between the supplying-side pipe and the collecting-side pipe; and a self power-generating unit which converts the temperature difference between the pipes or a temperature difference in at least two places around the pipes into electric energy by using a thermoelectric element, and which provides the electric energy as a power source for the heat meter.
