Description

Water chiller and air conditioning system

Technical Field

The present 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 air bubbles and water for cooling.

Background

In the existing chiller, a refrigerant (refrigerator) is compressed into a high-pressure high-temperature gaseous refrigerant by a compressor (compressor), and the gaseous refrigerant enters a condenser (condenser) to be condensed into high-pressure normal-temperature liquid cold coal, so that the refrigerant is vaporized by an expansion valve (expansion valve) in order to return to a low-temperature heat-absorbing state, the refrigerant forms a low-pressure low-temperature vaporization effect due to phase change, and then enters an evaporator to cool water at a load side. The refrigerant side of the evaporator also returns to a low-pressure gas state after absorbing heat, and returns to the compressor again for compression cycle, thereby achieving the effect of repeated refrigeration. In addition, the existing air conditioning system also commonly uses a compressor and a refrigerant to achieve an air cooling effect.

However, the power consumption of the compressor operation is large, and the carbon emission amount (carbon emissions) is increased. The use of the refrigerant can pollute the environment and accelerate the warming of the climate. And the coefficient of performance (coefficient of performance, COP) of refrigeration using compressors and refrigerants is generally poor.

referring to fig. 4A and 1, the drying gas a is obtained by adsorbing moisture in the mixture M of gas and water molecules by the regenerable drying agent 35 (e.g., molecular sieve, silica gel or graphene oxide) in the first adsorption portion 31, and the blower 20 then delivers the drying gas a to the gas disperser 12 (e.g., the hollow shell 120) through the hot portion 42 of the heat exchanger 40 via the third valve 73 to generate the plurality of bubbles B. Since the heat of adsorption of the moisture by the regenerable drying agent 35 heats the drying gas a, the drying gas a exhibits a high temperature (about 75 to 85 ℃) and the drying gas a having a high temperature reduces the water cooling efficiency, the drying gas a having a high temperature exchanges heat with the mixture M of the gas and water molecules having a low temperature passing through the cold part 41 of the heat exchanger 40 while passing through the hot part 42 of the heat exchanger 40, so as to reduce the temperature of the drying gas a. Further, 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 (e.g., the moisture adsorbed by the regenerable drying agent 35) in the first desorption part 32. And the first regulating valve 81 and the fourth regulating valve 84 may be opened at an appropriate timing so that a small portion (less than 10%) of the dry gas a passes through the first regulating valve 81 to enter the first desorption portion 32, and water molecules (water molecules) desorbed in the first desorption portion 32 are discharged to the external environment through the fourth regulating valve 84; and

In some embodiments, the cooling water W' may be delivered to an external device through the port 112 of the housing 11 for cooling or air conditioning purposes.

The drying gas a is obtained by adsorbing moisture in the gas and water molecule mixture M by the regenerable desiccant 35 (e.g., molecular sieve, silica gel or graphene oxide) in the second adsorption portion 31', and the blower 20 then conveys the drying gas a through the fourth valve 74, through the hot portion 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 part 31' may be transferred to the second desorption part 32' (fig. 4B) through the heat exchange part 33 to desorb moisture (e.g., moisture adsorbed by the regenerable drying agent 35) in the second desorption part 32 '. And the second regulating valve 82 and the third regulating valve 83 may be opened at an appropriate timing so that a small portion (less than 10%) of the dry gas a passes through the second regulating valve 82 to the second desorption portion 32', and water molecules desorbed in the second desorption portion 32' are discharged to the external environment through the third regulating valve 83; and

The plurality of bubbles B and the water W are utilized to generate turbulent motion so as to form a mixture M of the gas and the water molecules and reduce the temperature of the water W to obtain the cooling water W'.

In the embodiment shown in fig. 1 to 4B, the refrigeration medium of the water chiller 1 uses only water and gas, and no refrigerant is used at all, so that no pollution to the environment and accelerated climate warming are caused. And the present utility model uses only the blower 20 with low power consumption, the carbon emission (carbon emissions) is much lower than that of the existing compressor. In addition, the coefficient of performance (COP) of the air blower 20, water and gas refrigeration can reach more than 15, which is obviously superior to the COP of the existing compressor and refrigerant.
