摘要： The present invention relates to a fuel cell system comprising: a fuel cell configured to generate electricity and heat by a reaction between hydrogen and oxygen; a heat storage tank provided therein with a storage heat exchange unit configured to perform heat exchange between the heat recovered from the fuel cell and a fluid contained in the heat storage tank; a heat media supply line and a heat media recovery line configured to interconnect the fuel cell and the storage heat exchange unit to form a circulation flow channel of heat media; a bypass line branched from the heat media supply line and connected to the heat media recovery line; a flow channel switching device configured to selectively switch the flow channel of the heat media flowing along the heat media supply line to the storage heat exchange unit or the bypass line; and a controller configured to control the flow channel switching device such that the flow channel of the heat media flowing along the heat media supply line is connected to the storage heat exchange unit when the fuel cell generates power, and the flow channel of the heat media flowing along the heat media supply line is connected to the bypass line when the fuel cell stops power generation.

摘要： Provided is a method for measuring the temperature at each location of a pipe in a hot water supply system comprising a water heater, a pipe, and outlets, the method comprising checking for a temperature of a first point (TP1), which is upstream of the outlet, a temperature of a second point (TP2), which is downstream of the outlet and an outdoor temperature (TA), and confirming a length (L) of the pipe from the first point to the second point, then measuring a temperature of the pipe located at a distance of x away from the first point.
