Description

Chiller, air conditioning system and water cooling method Technical Field

[0001] The present invention relates to a water chiller, an air conditioning system and a water cooling method, and more particularly to a water chiller, an air conditioning system and a water cooling method using air bubbles and water for cooling. Background Art

[0002] Existing chillers primarily use a compressor to compress the refrigerant into a high-pressure, high-temperature gaseous refrigerant. This refrigerant then enters a condenser to condense into a high-pressure, room-temperature liquid refrigerant. To return the refrigerant to a low-temperature, heat-absorbing state, an expansion valve is used to vaporize it. The phase change causes the refrigerant to vaporize at a low pressure and low temperature, before it enters the evaporator, allowing the water on the load side to be cooled and cooled. After absorbing heat, the refrigerant on the evaporator returns to a low-pressure gaseous state and returns to the compressor for another compression cycle, achieving a repeated cooling effect. Furthermore, existing air conditioning systems also commonly use compressors and refrigerants to achieve air cooling.

[0003] However, compressor operation consumes a lot of electricity, increasing carbon emissions. The use of refrigerants pollutes the environment and accelerates global warming. Furthermore, the coefficient of performance (COP) of refrigeration using compressors and refrigerants is generally poor.

[0004] Summary of the Invention

[0005] In some embodiments, a water chiller includes a gas dryer, a gas disperser, and a blower. The gas disperser is disposed in water and is configured to generate a plurality of bubbles. The bubbles and the water generate turbulent motion to form a mixture of gas and water molecules, lowering the temperature of the water to produce cooling water. The blower is connected to the gas dryer and is configured to deliver the mixture of gas and water molecules into the gas dryer to remove water from the mixture to produce dry gas, and then deliver the dry gas to the gas disperser to generate the plurality of bubbles.

[0006] In some embodiments, an air conditioning system includes a chiller, a fan coil unit, and a water pump. The fan coil unit is connected to the chiller and configured to receive cooling water. The water pump is connected to the fan coil unit and the chiller at both ends to drive the cooling water into and out of the fan coil unit, thereby generating cool air from the fan coil unit.

[0007] In some embodiments, a water cooling method includes: generating a plurality of bubbles in water through a gas disperser, and utilizing the plurality of bubbles to generate turbulent motion with the water to form a mixture of gas and water molecules and reduce the temperature of the water to obtain cooling water; sending the gas and water molecule mixture into a gas dryer through a blower to remove water from the gas and water molecule mixture to obtain a dry gas; and delivering the dry gas to the gas disperser to generate the plurality of bubbles.

[0015] FIG1 is a schematic diagram of a water chiller 1 according to some embodiments of the present invention. Referring to FIG1 , the water chiller 1 of the present invention may include a bubble evaporator 10 , a heat exchanger 40 , a gas dryer 30 , and a blower fan 20 .

[0016] In some embodiments, as shown in Figure 1, the bubble vaporizer 10 may include a housing 11 and a gas diffuser 12. The housing 11 can be connected to a water source 91 to receive water W. In some embodiments, the housing 11 may have a top 11a, a bottom 11b and a middle portion 11c. The top 11a can be connected to the water source 91, and the top 11a can have at least one port (including, for example, port 111). The bottom 11b is relative to the top 11a, and the bottom 11b can have at least one port (including, for example, port 112). The middle portion 11c is located between the top 11a and the bottom 11b. In some embodiments, the volume of the middle portion 11c may be greater than the volume of the top 11a and the volume of the bottom 11b.

[0017] In some embodiments, as shown in FIG1 , the housing 11 may include a first baffle 118 and a second baffle 119. The first baffle 118 and the second baffle 119 may be connected to an inner sidewall 11w of the housing 11 and may be spaced apart from each other. In other words, a gap G may be defined between the first baffle 118 and the second baffle 119. In some embodiments, a downward projection of a portion of the first baffle 118 corresponding to the gap G overlaps an upward projection of a portion of the second baffle 119 corresponding to the gap G.

[0018] 2 , which shows a schematic diagram of a bubble vaporizer according to some embodiments of the present invention, in some embodiments, as shown in FIG2 , the width of the housing 11 (eg, the width of the middle portion 11 c ) can taper downward.

[0019] Referring again to FIG. 1 , the gas disperser 12 may be disposed within the housing 11 and disposed in the water W to contact the water W. The gas disperser 12 is configured to generate a plurality of gas bubbles B. Thus, the gas disperser 12 and the housing 11 may constitute the bubble evaporator 10. In some embodiments, the turbulent motion generated by the gas bubbles B and the water W may form a mixture of gas and water molecules M, lowering the temperature of the water W to produce chilled water W'. In some embodiments, the turbulent motion generated by the gas bubbles B and the water W to form the gas and water molecule mixture M and lowering the temperature of the water W may also be referred to as a "cooling mechanism by bubble enhanced evaporation." In some embodiments, the gas and water molecule mixture M may enter the port 111 through the gap G and be discharged, and the first baffle 118 and the second baffle 119 may prevent the water W from splashing during the turbulent motion.

[0020] Referring to FIG3 , a schematic diagram of a gas disperser according to some embodiments of the present invention is shown. In some embodiments, as shown in FIG1 and FIG3 , the gas disperser 12 may include a hollow housing 120. The hollow housing 120 may be positioned adjacent to the bottom 11 b of the housing 11. In some embodiments, as shown in FIG1 , the hollow housing 120 may not contact (including, for example, not contacting at all or not directly contacting) the housing 11 (e.g., the inner sidewall 11 w).

[0021] In some embodiments, as shown in FIG3 , the hollow housing 120 may have a top 121 , an air chamber 124 , and a plurality of air holes 125 . The air chamber 124 is configured to receive a dry gas A. In some embodiments, the dry gas A may include, but is not limited to, air. The plurality of air holes 125 may penetrate the hollow housing 120 and communicate with the air chamber 124 , allowing the dry gas A to pass through the plurality of air holes 125 to generate the plurality of bubbles B. In some embodiments, the plurality of air holes 125 may be disposed on the top 121 of the hollow housing 120 .

[0022] In some embodiments, the gas disperser 12 may include a porous material having a plurality of holes for the dry gas A to pass through to generate the plurality of bubbles B.

[0023] Referring again to FIG. 1 , the heat exchanger 40 can be connected to the housing 11 and the gas disperser 12 . In some embodiments, as shown in FIG. 1 , the heat exchanger 40 can include a cold portion 41 and a hot portion 42 . One end of the cold portion 41 can be connected to the housing 11 (e.g., the port 111 ). One end of the hot portion 42 can be connected to the gas disperser 12 (e.g., the hollow housing 120 ) via a gas line 128 .

[0024] The gas dryer 30 can be connected to the gas disperser 12 via the heat exchanger 40 (e.g., the hot section 42). In other words, the hot section 42 of the heat exchanger 40 can be connected to the gas dryer 30 and the gas disperser 12 at both ends, respectively. In some embodiments, as shown in FIG1 , the gas dryer 30 can be connected to the hot section 42 of the heat exchanger 40 via at least one valve (e.g., including a third valve 73 and a fourth valve 74).

[0025] In some embodiments, as shown in FIG1 , the gas dryer 30 may include a first adsorption portion 31, a first desorption portion 32, and a heat exchanging portion 33. The first adsorption portion 31 and the first desorption portion 32 may include a renewable desiccant 35. In some embodiments, the regenerable desiccant 35 may include, but is not limited to, an adsorption-type regenerable desiccant. In some embodiments, the regenerable desiccant 35 may include, but is not limited to, molecular sieves, silica gels, or graphene oxides. In some embodiments, the regenerable desiccant 35 may be regenerated by heating. In some embodiments, as shown in FIG1 , the first adsorption portion 31 may be connected to the hot portion 42 of the heat exchanger 40 via the third valve 73, and the first desorption portion 32 may be connected to the hot portion 42 of the heat exchanger 40 via the fourth valve 74. In some embodiments, the third valve 73 and the fourth valve 74 can be used alternately, that is, when the third valve 73 is opened, the fourth valve 74 can be closed; when the fourth valve 74 is opened, the third valve 73 can be closed.

[0026] The heat exchange section 33 may be disposed between the first adsorption section 31 and the first desorption section 32. Thus, the first adsorption section 31 is connected to the first desorption section 32 via the heat exchange section 33. In some embodiments, the first adsorption section 31 may be defined as the area where the regenerable desiccant 35 has not yet absorbed moisture, while the first desorption section 32 may be defined as the area where the regenerable desiccant 35 has absorbed moisture and requires desorption and regeneration. The adsorption heat generated by the first adsorption section 31 may be transferred to the first desorption section 32 via the heat exchange section 33 to desorb moisture from the first desorption section 32 (e.g., moisture adsorbed by the regenerable desiccant 35).

[0027] In some embodiments, as shown in Figure 1, the first adsorption section 31 can be connected to the first desorption section 32 via a first regulating valve 81, and the first desorption section 32 can be connected to the first adsorption section 31 via a second regulating valve 82. In some embodiments, the first regulating valve 81 and the second regulating valve 82 can be used alternately. That is, when the first regulating valve 81 is open, the second regulating valve 82 can be closed; when the second regulating valve 82 is open, the first regulating valve 81 can be closed. In some embodiments, the flow direction of the first regulating valve 81 can be opposite to that of the second regulating valve 82. In addition, in some embodiments, the first adsorption section 31 can be connected to an external environment via a third regulating valve 83, and the first desorption section 32 can be connected to the external environment via a fourth regulating valve 84. In some embodiments, the first regulating valve 81, the second regulating valve 82, the third regulating valve 83, and the fourth regulating valve 84 can include, but are not limited to, needle valves.

[0028] The blower 20 can be connected to the gas dryer 30 (including, for example, the first adsorption section 31 and the first desorption section 32). In some embodiments, as shown in FIG1 , the first adsorption section 31 can be connected to the blower 20 via a first valve 71, and the first desorption section 32 can be connected to the blower 20 via a second valve 72. In some embodiments, the first valve 71 and the second valve 72 can be used alternately. That is, when the first valve 71 is open, the second valve 72 can be closed; and when the second valve 72 is open, the first valve 71 can be closed.

[0029] Furthermore, the housing 11 (e.g., the top portion 11a) can be connected to the blower 20 via the heat exchanger 40 (e.g., the cold portion 41). That is, the two ends of the cold portion 41 of the heat exchanger 40 can be connected to the blower 20 and the top portion 11a of the housing 11 (e.g., the port 111), respectively. The blower 20 is used or configured to discharge the gas and water molecule mixture M within the housing 11 and to deliver the gas and water molecule mixture M to the gas dryer 30 (e.g., the first adsorption portion 31) to remove water from the gas and water molecule mixture M to obtain the dry gas A (near zero relative humidity). The dry gas A is then delivered to the gas disperser 12 (e.g., the hollow housing 120) to generate the plurality of bubbles B. In order to enable the blower 20 to quickly discharge the gas and water molecule mixture M in the housing 11 and to deliver the dry gas A to the gas disperser 12 (e.g., the hollow housing 120) at high pressure, in some embodiments, the pressure ratio of the blower 20 may be 1.1 to 1.2. In some embodiments, as shown in FIG1 , the blower 20 may be connected to a gas source 92 via a regulating valve 85 to ensure sufficient gas. In some embodiments, the regulating valve 85 may include, but is not limited to, a needle valve. In some embodiments, the gas source 92 may include, but is not limited to, the atmosphere.

[0030] Through the above configuration, the bubble vaporizer 10 (including, for example, the shell 11 and the gas disperser 12), the heat exchanger 40 (including, for example, the cold part 41 and the hot part 42), the blower 20 and the gas dryer 30 (including, for example, the first adsorption part 31 and the first desorption part 32) can be connected into a closed loop.

[0031] FIG4A and FIG4B are schematic diagrams showing one or more stages of operation of a gas dryer according to some embodiments of the present invention. The operation of the chiller 1 is described in detail with reference to FIG1 , FIG4A and FIG4B as follows:

[0032] [First operation cycle]

[0033] 1 , the regulating valve 85 , the first valve 71 and the third valve 73 are opened, and the remaining valves are closed;

[0034] Starting the blower 20 to discharge the gas and water molecule mixture M in the housing 11 and sending the gas and water molecule mixture M into the first adsorption part 31 of the gas dryer 30 through the first valve 71;

[0035] Referring to FIG. 4A and FIG. 1 , the regenerable desiccant 35 (e.g., molecular sieve, silica gel, or graphene oxide) in the first adsorption section 31 absorbs water from the gas and water mixture M to produce the dry gas A. The blower 20 then delivers the dry gas A through the third valve 73 and the hot section 42 of the heat exchanger 40 to the gas disperser 12 (e.g., the hollow housing 120 ), thereby generating the plurality of bubbles B. The heat of adsorption generated by the regenerable desiccant 35 heating the dry gas A causes it to reach a high temperature (approximately 75° C. to 85° C.). High-temperature dry gas A reduces water cooling efficiency. Therefore, while passing through the hot section 42 of the heat exchanger 40, the high-temperature dry gas A exchanges heat with the low-temperature gas and water mixture M passing through the cold section 41 of the heat exchanger 40, thereby reducing the temperature of the dry gas A. Furthermore, the adsorption heat generated by the first adsorption section 31 can be transferred to the first desorption section 32 via the heat exchange section 33 to desorb the moisture (e.g., moisture adsorbed by the regenerable desiccant 35) in the first desorption section 32. Furthermore, the first regulating valve 81 and the fourth regulating valve 84 can be opened at an appropriate time to allow a small portion (less than 10%) of the dry gas A to enter the first desorption section 32 through the first regulating valve 81, and the water molecules desorbed from the first desorption section 32 to be discharged to the external environment through the fourth regulating valve 84.

[0036] The gas and water molecule mixture M is formed by generating turbulent motion between the bubbles B and the water W, and the cooling water W' is obtained by lowering the temperature of the water W. In some embodiments, the cooling water W' can be delivered to an external device through the port 112 of the housing 11 for cooling or air conditioning purposes.

[0037] In some embodiments, as shown in FIG. 4A and FIG. 4B , the first desorption section 32 ( FIG. 4A ) after water desorption can be used as a second adsorption section 31 ′ ( FIG. 4B ), and the first adsorption section 31 ( FIG. 4A ) after water adsorption can be used as a second desorption section 32 ′ ( FIG. 4B ).

[0038] [Second operation cycle]

[0039] 1 , the regulating valve 85 , the second valve 72 , and the fourth valve 74 are opened, and the remaining valves are closed;

[0040] 1 and 4B , the blower 20 is started to discharge the gas and water molecule mixture M in the housing 11 and to deliver the gas and water molecule mixture M into the second adsorption portion 31 ′ ( FIG. 4B ) of the gas dryer 30 through the second valve 72 ;

[0041] The regenerable desiccant 35 (e.g., molecular sieve, silica gel, or graphene oxide) in the second adsorption section 31' adsorbs water from the mixture of gas and water molecules M to obtain the dry gas A. The blower 20 then transports the dry gas A through the fourth valve 74 and the hot section 42 of the heat exchanger 40 to the gas disperser 12 (e.g., the hollow housing 120) to generate the plurality of bubbles B. In addition, the adsorption heat generated by the second adsorption section 31' can be conducted to the second desorption section 32' ( FIG. 4B ) via the heat exchange section 33 to desorb the water (e.g., water adsorbed by the regenerable desiccant 35) in the second desorption section 32'. At an appropriate time, the second regulating valve 82 and the third regulating valve 83 can be opened to allow a small portion (less than 10%) of the dry gas A to enter the second desorption section 32' through the second regulating valve 82, and the water molecules desorbed from the second desorption section 32' are discharged to the external environment through the third regulating valve 83; and

[0042] The bubbles B and the water W generate turbulent motion to form the gas and water molecule mixture M and reduce the temperature of the water W to obtain the cooling water W′.

[0043] In the embodiment shown in Figures 1 to 4B , the chiller 1 uses only water and gas as the cooling medium, without any refrigerant. Therefore, it does not pollute the environment or accelerate global warming. Furthermore, the present invention utilizes only the low-power blower 20, resulting in carbon emissions far lower than those of conventional compressors. Furthermore, the present invention's use of the blower 20, water, and gas for cooling can achieve a coefficient of performance (COP) exceeding 15, significantly exceeding the COP of conventional systems using a compressor and refrigerant.

[0044] FIG5 is a schematic diagram of an air conditioning system 5 according to some embodiments of the present invention. Referring to FIG5 , the air conditioning system 5 of the present invention may include a chiller 1 , a fan coil unit 50 , and a water pump 58 .

In some embodiments, as shown in Figure 5, the fan coil unit 50 may include an air filter 51, a coil 52 and a fan 53. The air filter 51 may be configured to filter air. The coil 52 may be configured to allow the cooling water W' to pass through to cool the filtered air. The fan 53 may be configured to blow the filtered air toward the coil 52. In some embodiments, one end of the coil 52 (for example, the outlet end) may be connected to a port 113 of the housing 11. In some embodiments, the elevation of the port 113 may be different from the elevation of the port 112. In some embodiments, the port 113 may be disposed in the middle portion 11c of the housing 11.

[0047] The two ends of the water pump 58 can be connected to the fan coil unit 50 (e.g., the coil 52) and the chiller 1 (e.g., the port 112 of the housing 11), respectively, to drive the cooling water W' in and out of the fan coil unit 50 (e.g., the coil 52) so that the fan coil unit 50 generates cold air.
