Description

Chiller and air conditioning system

Technical Field

The utility model relates to a water chiller and an air conditioning system, and more particularly to a water chiller and an air conditioning system using bubbles and water for cooling.

Background technique

The existing chiller mainly compresses the refrigerant into a high-pressure and high-temperature gaseous refrigerant through a compressor, and enters the condenser to condense into a high-pressure and room-temperature liquid refrigerant. In order to return the refrigerant to a low-temperature state where it can absorb heat, an expansion valve is used to vaporize it. The refrigerant forms a low-pressure and low-temperature vaporization effect due to phase change, and then enters the evaporator so that the water on the load side can be cooled and cooled. The refrigerant side of the evaporator also returns to a low-pressure gas state after absorbing heat, and returns to the compressor for compression cycle again, achieving a repeated refrigeration effect. In addition, existing air conditioning systems also generally use compressors and refrigerants to achieve air cooling effects.

However, the high power consumption of compressors will increase carbon emissions. The use of refrigerants will pollute the environment and accelerate global warming. In addition, the coefficient of performance (COP) of refrigeration using compressors and refrigerants is generally poor.

The heat exchange part 33 may be disposed between the first adsorption part 31 and the first desorption part 32, so the first adsorption part 31 may be connected to the first desorption part 32 through the heat exchange part 33. In some embodiments, the first adsorption part 31 may be defined as the regenerable desiccant 35 that has not yet adsorbed moisture, and the first desorption part 32 may be defined as the regenerable desiccant 35 that has adsorbed moisture and needs to be desorbed and regenerated. The adsorption heat generated by the first adsorption part 31 may be conducted to the first desorption part 32 through the heat exchange part 33 to desorb the moisture in the first desorption part 32 (e.g., the moisture adsorbed by the regenerable desiccant 35).

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.

FIG. 4A to FIG. 4B 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 FIG. 1 , FIG. 4A and FIG. 4B as follows:

[First operation cycle]

Referring to FIG. 1 , the regulating valve 85 , the first valve 71 and the third valve 73 are opened, and the remaining valves are closed;

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;

Referring to FIG. 4A and FIG. 1 , the regenerable desiccant 35 (e.g., molecular sieve, silica gel, or graphene oxide) in the first adsorption part 31 adsorbs water in the mixture of gas and water molecules M to obtain the dry gas A, and the blower 20 then delivers the dry gas A through the third valve 73 and the hot part 42 of the heat exchanger 40 to the gas disperser 12 (e.g., the hollow housing 120) to generate the plurality of bubbles B. Since the adsorption heat generated by the adsorption of water by the regenerable desiccant 35 has a heating effect on the dry gas A, the dry gas A will be at a high temperature (about 75° C. to 85° C.), and the high temperature of the dry gas A will reduce the water cooling efficiency. Therefore, when the high temperature dry gas A passes through the hot part 42 of the heat exchanger 40, it can exchange heat with the low temperature mixture of gas and water molecules M passing through the cold part 41 of the heat exchanger 40 to reduce the temperature of the dry gas A. In addition, the adsorption heat generated by the first adsorption section 31 can be transferred to the first desorption section 32 through the heat exchange section 33 to desorb the moisture in the first desorption section 32 (for example, the moisture adsorbed by the regenerable desiccant 35). 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 in the first desorption section 32 can be discharged to the external environment through the fourth regulating valve 84; and

The gas and water molecule mixture M is formed by using the multiple bubbles B and the water W to generate turbulent motion 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.

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 ).

[Second operation cycle]

Referring to FIG. 1 , the regulating valve 85 , the second valve 72 and the fourth valve 74 are opened, and the remaining valves are closed;

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

The dry gas A is obtained by adsorbing the water in the mixture M of gas and water molecules through the regenerable desiccant 35 (e.g., molecular sieve, silica gel, or graphene oxide) in the second adsorption section 31', and 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 shell 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) through the heat exchange section 33 to desorb the water in the second desorption section 32' (e.g., the water adsorbed by the regenerable desiccant 35). The second regulating valve 82 and the third regulating valve 83 can be opened at an appropriate time 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 in the second desorption section 32' are discharged to the external environment through the third regulating valve 83; and

The gas and water molecule mixture M is formed by utilizing the multiple bubbles B and the water W to generate turbulent motion and the temperature of the water W is reduced to obtain the cooling water W′.

In the embodiment shown in FIG. 1 to FIG. 4B , the cooling medium of the water chiller 1 only uses water and gas, and no refrigerant is used at all, so it will not pollute the environment and accelerate global warming. Moreover, the utility model only uses the blower 20 with low power consumption, and its carbon emissions are much lower than the compressor used in the prior art. In addition, the coefficient of performance (COP) of the utility model using the blower 20, water and gas refrigeration can reach more than 15, which is significantly better than the COP of the prior art using compressors and refrigerants.
