Fig. 1 is damping thermoregulating system integral system schematic diagram.
As shown in Figure 1, damping thermoregulating system 100, has temperature control portion, heat convection and holds wet unit and regeneration of waste liquor unit.Wherein, temperature control portion comprises evaporimeter 1, choke valve 2, compressor 3 and condenser 4.These four parts form a loop, and indoor temperature is controlled.Heat convection holds wet unit and comprises convection current drum 12 and base 18.Regeneration of waste liquor unit comprises solution regenerator 5 and solution heat exchanger 7, between solution regenerator 5 and base 18, by the first pipeline 16, is connected with second pipe 17.Holding wet liquid (only having shown in figure that it flows to) is held between wet unit and regeneration of waste liquor unit 5 and circulates at heat convection by the first pipeline 16 and second pipe 17.Evaporative cooling unit has plate type heat exchanger 10 and the 3rd circulating pump 9.According to the difference with refrigeration mode and indoor humidity and outdoor temperature that heats of air-conditioning, native system can regulate the temperature of room air 15.
When Summer Indoor temperature and humidity is all higher, temperature control portion opens, to the indoor operation of lowering the temperature, the exhaust outlet of condenser 4 is to outdoor discharge hot-air 13, now control part (not shown) control triple valve makes the air outlet of condenser 4 provide hot blast to solution regenerator 5, and 13 in Fig. 1 shown the direction of motion of hot blast.Hot blast heats the wet liquid that holds in solution regenerator 5, makes to hold the water evaporates in wet liquid, thereby forms the wet liquid that holds of high concentration.The wet liquid that holds of high concentration enters convection current drum 12 by the first pipeline 16, and flows down from its surface, and saturated solution absorbs the moisture in room air 15, thereby reaches the effect of dehumidifying.Absorbed moisture in air saturated solution concentration afterwards and declined, after base 18 is collected, by second pipe 17, entered in solution regenerator 5 and again concentrate.
