摘要:
There is provided a system including: an automatic supplement valve configured to automatically supplementing direct water; an expansion tank configured to be connected to the automatic supplement valve to adjust expansion pressure depending on the temperature change of the direct water; an exhaust heat pump configured to be connected to the expansion tank to circulate heat in an exhaust heat line connecting the exhaust heat source and the hot water tank; and a mixing valve configured to be extendedly formed between a first hot water (1H) line for receiving the exhaust heat of the exhaust heat source and a second hot water (2H) line having passed through the exhaust heat exchanger of the hot water tank to mix the first hot water (1H) with the second hot water (2H).
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.
