Winter normal mode:When outdoor dry-bulb temperature is higher than setting value in the winter time, using heat source tower from outdoor air institute Caloric receptivity can meet the low-grade heat demand of unit, now heat source tower separately as unit low level heat energy, while underground pipe, Solar heat-collection plate series operation, for the heat needed for the regenerating unit of unit provides solution regeneration.Now, the first magnetic valve, Second magnetic valve, the 4th magnetic valve, the 8th magnetic valve, the 9th magnetic valve, the 12nd magnetic valve are opened, remaining closed electromagnetic valve (Depending on 5th magnetic valve, the action apparent sun radiation intensity of the 13rd magnetic valve), the first pump, the second pump and the 3rd pump are opened. Under the operational mode, the circulatory mediator in heat source tower loop is solution, and First Heat Exchanger is used as condenser, the second heat exchanger conduct Evaporator.The refrigerant gas of low-temp low-pressure is become high from gas-liquid separator after compressor suction compression in refrigerant loop Warm high pressure superheated vapor discharge, enters in First Heat Exchanger, refrigerant exchanges heat with hot water by four-way reversing valve, releases heat, Condensation becomes liquid, is flowed out from First Heat Exchanger, reservoir, filter, expansion valve are sequentially passed through after the first check valve Become the gas-liquid two-phase of low-temp low-pressure afterwards, then enter the second heat exchanger by the 4th check valve, refrigerant is in the second heat exchanger Exchanged heat with solution, become overheated gas after refrigerant heat absorption evaporating completely passes through four-way reversing valve from the outflow of the second heat exchanger Into gas-liquid separator, then sucked and compress by compressor again, so as to complete to heat circulation, realize hot water preparing.Heat source tower In loop, solution is flowed out after releasing thermal temperature reduction, entered through the second magnetic valve in the second heat exchanger and refrigerant heat exchanger Heat source tower, solution carries out heat and mass in heat source tower with air, after solution temperature rise, from the outflow of the output end of heat source tower first Solution be divided into two parts, most solutions are pumped into the second heat exchanger after the first magnetic valve by the first pump, complete solution circulation.
