if the aim is cooling, the circulating working medium flows into a compressor (10) to compress and apply work after cooling the fuel cell stack (1) through a stack cooling loop (4); the high-temperature working medium flows into an outdoor heat exchanger (12) through a four-way reversing valve (9) to perform flowing heat exchange with a cooling tower water tank (13) loop, and the obtained high-temperature working medium is subjected to heat exchange with the outdoor environment through the cooling tower water tank (13) loop to reduce the temperature; circulating working media flow into the indoor heat exchanger (8) and a fan coil system (6) loop through the expansion valve (11) to perform expansion and heat absorption, and the fan coil system (6) loop uses a fan to blow out cold air to refrigerate the building through the obtained cooling working media; the circulating working medium flows out of the indoor heat exchanger (8) and flows into the galvanic pile cooling loop (4) to cool the fuel cell galvanic pile (1);
if the aim is heat supply, the circulating working medium cools the fuel cell stack (1) through the stack cooling loop (4), preheats the working medium and then flows into the compressor (10) to compress and apply work; the air flows into an indoor heat exchanger (8) through a four-way reversing valve (9) to perform flowing heat exchange with a fan coil system (6) loop, and the fan coil system (6) loop heats a building by using hot air blown out by a fan through the obtained high-temperature working medium; circulating working media flow into an outdoor heat exchanger (12) and a cooling tower water tank (13) loop through an expansion valve (11) to expand and absorb heat, and the cooling tower water tank (13) loop exchanges heat with the outdoor environment through the obtained low-temperature working media and heats the low-temperature working media; the circulating working medium flows out of the outdoor heat exchanger (12), flows into the galvanic pile cooling loop (4) to cool the fuel cell galvanic pile (1) and preheats the working medium;
if the target is humidification, the outlet of the heat preservation water tank (18) is opened to enable the stored water to flow into the wet film material (16) through the water distributor (15), and the air flow of the fan coil system (6) of the refrigeration and heating module (II) is utilized to blow out the water to humidify the building;
if the defrosting is aimed, the gas path outlet of the gas-liquid separator (5) is opened, and gas with certain heat is led to the outdoor heat exchanger (12) to defrost the outdoor heat exchanger (12).
