[0024] A winter workflow of the all-weather solar water source heat pump air conditioning system in the present invention is as follows:

[0025] 1. The liquid water circulating pump (1-7) is started, and anti-freezing solution is extracted from the aqueous solution heat exchange box (2-1), fed to the spraying pipeline (1-5) through the circulating pipeline A, sprayed to the mixing plate (1-3) by virtue of the spraying pipeline (1-5) and then drops into the water storage pool (1-6) by virtue of gravity; the fan (1-2) is started, and air enters the frame body (1-1) from the diversion plate (1-4) and is discharged from the fan (1-2) after passing through the mixing plate (1-3). In the frame body (1-1), heat and mass transfer is performed between the air and the anti-freezing solution at the mixing plate (1-3), and heat and humidity in the air are transferred to the anti-freezing solution, thereby increasing a temperature of the anti-freezing solution and decreasing a concentration of the anti-freezing solution;

[0026] 2. The anti-freezing solution flows out of the water storage pool (1-6), drops into the aqueous solution heat exchange box (2-1) through the circulating pipeline B by virtue of natural gravity and pushes a turbine to generate power while passing through the turbine generator (5-1), and the energy storage control apparatus (5-2) controls a turbine power generation state according to an operating state of the turbine generator (5-1) and then stores energy;

[0027] 3. The anti-freezing solution enters the aqueous solution heat exchange box (2-1), and a flow direction and a flow state of the anti-freezing solution are changed under an action of the stirrer (2-3). While flowing through the micro-channel superconducting heat exchanger (2-2), the anti-freezing solution performs heat exchange with a refrigerant in the micro-channel superconducting heat exchanger (2-2), a temperature of the anti-freezing solution is decreased after heat is transferred to the refrigerant, and then the anti-freezing solution flows out of the aqueous solution heat exchange box (2-1) again and enters the circulating pipeline A, thereby completing a cycle of the anti-freezing solution;

[0028] 4. The concentration controller (2-4) is mounted at the outlet pipeline of the aqueous solution heat exchanger (2-1), a concentration of the anti-freezing solution at the outlet of the aqueous solution heat exchanger (2-1) is sensed, and the concentration circulating pump (4-2) is started to concentrate the anti-freezing solution after the concentration of the anti-freezing solution is decreased to a certain degree;

[0029] 5. The anti-freezing solution in the aqueous solution heat exchange box (2-1) is fed into the concentration water tank (4-1) by the concentration circulating pump (4-2) through the pipeline C for concentrating the anti-freezing solution, and the concentrated anti-freezing solution enters the aqueous solution heat exchange box (2-1) again through the pipeline D and is recycled;

[0030] 6. A liquid low-temperature refrigerant flows through the micro-channel superconducting heat exchanger (2-2), absorbs heat of the anti-freezing solution outside the heat exchanger and is changed into a gaseous refrigerant from a liquid state to enter the heat pump main engine (3), and the gaseous refrigerant is changed into a liquid low-temperature refrigerant again to enter the micro-channel superconducting heat exchanger (2-2), thereby completing a refrigerant cycle.

[0031] A summer workflow is as follows:

[0032] 1. The liquid water circulating pump (1-7) is started, and cooling water is extracted from the aqueous solution heat exchange box (2-1), fed to the spraying pipeline (1-5) through the circulating pipeline A, sprayed to the mixing plate (1-3) by virtue of the spraying pipeline (1-5) and then drops into the water storage pool (1-6) by virtue of gravity; the fan (1-2) is started, and air enters the frame body (1-1) from the diversion plate (1-4) and is discharged from the fan (1-2) after passing through the mixing plate (1-3). In the frame body (1-1), heat and mass transfer is performed between the air and the cooling water at the mixing plate (1-3), and heat in the cooling water is transferred to the air, thereby decreasing a temperature of the cooling water, evaporating the water and decreasing a water quantity;

[0033] 2. The cooling water flows out of the water storage pool (1-6), drops into the aqueous solution heat exchange box (2-1) through the circulating pipeline B by virtue of natural gravity and pushes the turbine to generate power while passing through the turbine generator (5-1), and the energy storage control apparatus (5-2) controls a turbine power generation state according to an operating state of the turbine generator (5-1) and then stores energy;

[0034] 3. The cooling water enters the aqueous solution heat exchange box (2-1), and a flow direction and a flow state of the cooling water are changed under an action of the stirrer (2-3). While flowing through the micro-channel superconducting heat exchanger (2-2), the cooling water performs heat exchange with a refrigerant in the micro-channel superconducting heat exchanger (2-2), a temperature of the cooling water is increased after heat of the refrigerant is absorbed, and then the cooling water flows out of the aqueous solution heat exchange box (2-1) again and enters the circulating pipeline A, thereby completing a cycle of the cooling water;

[0035] 4. A gaseous high-temperature refrigerant flows through the micro-channel superconducting heat exchanger (2-2), transfers heat of the cooling water outside the heat exchanger and is changed into a liquid refrigerant from a gaseous state to enter the heat pump main engine (3), and the liquid refrigerant is changed into a gaseous low-temperature refrigerant again to enter the micro-channel superconducting heat exchanger (2-2), thereby completing a refrigerant cycle;

[0036] 5. Low-temperature condensate water produced by a user of an indoor summer air conditioning system is collected together through the user condensate water pipeline system (6-1) and is connected to the aqueous solution heat exchange box (2-1) through a pipeline E. The low-temperature condensate water enters the aqueous solution heat exchange box (2-1) and then is mixed with the cooling water, a quantity of the cooling water is supplemented, and a temperature of the cooling water is decreased, thereby decreasing a condensation temperature of the refrigerant and increasing working efficiency of the heat pump main engine (3).

[0037] In year-round operation, by starting the fan (1-2), air carrying PM haze particles enters the frame body (1-1) from the diversion plate (1-4); the PM haze particles are absorbed by an aqueous solution sprayed from the spraying pipeline (1-5) to drop into the frame body (1-1), fall into the water storage pool (1-6) and then are precipitated in the PM2.5 haze purification particle precipitation apparatus (7-1); impurities in the PM haze particles are discharged and collected by the precipitated particle discharging apparatus (7-2) and the pipeline impurity filtering and discharging apparatus (7-3), thereby achieving purposes of purifying the outdoor air and treating the haze.

[0038] Valves are arranged on the pipeline C, the pipeline D and the pipeline E. The valve on the pipeline E is closed in winter and opened in summer, while the valves on the pipeline C and the pipeline D are opened in the winter and closed in the summer.
