As shown in fig. 1, the self-operated air conditioning cooling system of the magnetic levitation blower according to the present invention comprises a magnetic levitation blower 1, a pressure reducing valve 2, a first two-position five-way electromagnetic valve 3, a second two-position five-way electromagnetic valve 4, a third two-position five-way electromagnetic valve 5, a first pressure increasing cylinder 6, a second pressure increasing cylinder 7, a third pressure increasing cylinder 8, a first check valve 9, a second check valve 10, a third check valve 11, a fourth check valve 12, a fifth check valve 13, a sixth check valve 14, a seventh check valve 15, an eighth check valve 16, a ninth check valve 17, a tenth check valve 18, an eleventh check valve 19, a twelfth check valve 20, an air-cooled heat exchanger 22, a pressure gauge 23, a stop valve 24, an expansion valve 25, a first pipeline 111, a second pipeline 112 and a third pipeline 113, wherein the first pipeline 111, the second pipeline 112 and the third pipeline 113 are all connected to the magnetic levitation blower 1, the expansion valve 25, the air-cooled heat exchanger 22 and the pressure gauge 23 are all connected to the second pipeline 112, and the pressure gauge 24 and the stop valve 24 and the first pipeline 113 are connected to the first pipeline 111 and the third pipeline 113 respectively. The first two-position five-way electromagnetic valve 3, the second two-position five-way electromagnetic valve 4 and the third two-position five-way electromagnetic valve 5 are connected to the third pipeline 113, and the first booster cylinder 6, the second booster cylinder 7 and the third booster cylinder 8 are correspondingly connected with the first two-position five-way electromagnetic valve 3, the second two-position five-way electromagnetic valve 4 and the third two-position five-way electromagnetic valve 5 respectively.
Refrigerant cavities are respectively arranged at two ends of the two cylinder shafts in the first booster cylinder 6, two ends of the two cylinder shafts in the second booster cylinder 7 and two ends of the two cylinder shafts in the third booster cylinder 8.
The refrigerant cavity at the right end of the first booster cylinder 6 is correspondingly connected with a first pipeline 111 and a second pipeline 112 through a first one-way valve 9 and a second one-way valve 10, and the refrigerant cavity at the left end of the first booster cylinder 6 is correspondingly connected with the first pipeline 111 and the second pipeline 112 through a third one-way valve 11 and a fourth one-way valve 12.
The refrigerant cavity at the right end of the second booster cylinder 7 is correspondingly connected with the first pipeline 111 and the second pipeline 112 through the fifth one-way valve 13 and the sixth one-way valve 14, and the refrigerant cavity at the left end of the second booster cylinder 7 is correspondingly connected with the first pipeline 111 and the second pipeline 112 through the seventh one-way valve 15 and the eighth one-way valve 16.
The refrigerant cavity at the right end of the third booster cylinder 8 is correspondingly connected with the first pipeline 111 and the second pipeline 112 through a ninth one-way valve 17 and a tenth one-way valve 18, and the refrigerant cavity at the left end of the third booster cylinder 8 is correspondingly connected with the first pipeline 111 and the second pipeline 112 through an eleventh one-way valve 19 and a twelfth one-way valve 20.
When the magnetic suspension fan 1 is used, the outlet pressure of the fan is gradually increased, gas passes through the first two-position five-way electromagnetic valve 3, the second two-position five-way electromagnetic valve 4 and the third two-position five-way electromagnetic valve 5 and correspondingly enters the right end of the air cavity of the first pressurizing cylinder 6, the right end of the air cavity of the second pressurizing cylinder 7 and the right end of the air cavity of the third pressurizing cylinder 8, the gas correspondingly pushes pistons in the three pressurizing cylinders to move leftwards, and the pistons pressurize the refrigerants in the left refrigerant cavities in the three pressurizing cylinders in the moving process, so that the refrigerants are changed from gas to liquid, at the moment, the check valves (12, 16 and 20) are opened, and the check valves (11, 15 and 19) are closed.
The refrigerant enters the air-cooled heat exchanger 22 through the one-way valves (12, 16 and 20), the air-cooled heat exchanger takes away the heat of the refrigerant, the temperature of the refrigerant is reduced, the refrigerant with low temperature and high pressure passes through the expansion valve 25, the temperature of the refrigerant with low temperature and pressure reduction is further reduced, the liquid refrigerant with low temperature enters the main machine of the magnetic suspension fan 1 for heat exchange, and the refrigerant after heat exchange becomes a gas state.
When the piston moves leftwards, the check valves (9, 13, 17) are opened, the check valves (10, 14, 18) are closed, and the refrigerant enters the refrigerant cavity at the right end of the pressurizing cylinder (6, 7, 8). When the piston reaches the left end stroke, the two-position five-way electromagnetic valves (3, 4 and 5) are electrified and commutated, gas enters the left end of the air cavity of the pressurizing cylinder (6, 7 and 8), the gas pushes the piston to move rightwards, the piston pressurizes the refrigerant in the refrigerant cavity at the right end into a liquid state in the moving process, the one-way valves (10, 14 and 18) are opened, (9, 13 and 17) are closed, the refrigerant enters the air-cooled heat exchanger through the one-way valves (10, 14 and 18), meanwhile, the one-way valves (11, 15 and 19) are opened, the one-way valves (12, 16 and 20) are closed, and the refrigerant enters the refrigerant cavity at the right end of the pressurizing cylinder (6, 7 and 8). So reciprocating, the refrigerant continuously flows in the system for heat exchange. The pressure of the cooling system with low outlet pressure is also low when the fan is at low power, and the pressure of the cooling system with high outlet pressure is also high when the fan is at high power, so that energy is saved. When the outlet pressure of the fan is greater than 1bar, the pressure reducing valve 2 acts to enable the pressure of the gas passing through the electromagnetic valve to be not greater than 1bar, and the pressure of the refrigerant is not greater than 10 times of the pressure of the gas, namely 10bar, because the area of the piston of the air cavity of the booster cylinder is 10 times of the area of the piston of the liquid cavity (A1=10A2).
In the invention, the measuring range of the pressure gauge 23 is 0-16bar, and the stop valve 24 is a fluid supplementing valve.
The foregoing is merely a preferred embodiment of the invention, and it should be noted that modifications could be made by those skilled in the art without departing from the principles of the invention, which modifications would also be considered to be within the scope of the invention.
