During summer, drive lithium-bromide absorption-type refrigerating machine and be hot water in first hot water storage tank with heating agent, control the unlatching of the first refrigeration machine driving pump and lithium-bromide absorption-type refrigerating machine by the temperature of the indoor temperature-sensing probe detection of building, when indoor temperature is higher than setting value, the first refrigeration machine driving pump, lithium-bromide absorption-type refrigerating machine start automatically, lithium-bromide absorption-type refrigerating machine starts the back and produces chilled water, delivers to building room conditioning end; When the first hot water storage tank water temperature does not reach requirement, lithium-bromide absorption-type refrigerating machine is opened auxiliary energy system automatically and is begun to carry out kind of refrigeration cycle, stops when reaching indoor design temperature;
During winter, when indoor temperature, the first hot water storage tank water temperature reach setting value, heating system, the second heating pump automatic start-stop will be through the delivery after the heat exchange of three-plate type heat exchanger to building indoor heating ends.
