DETAILED DESCRIPTION OF THE INVENTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described hereinafter in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the protection scope of the present invention.

Embodiment 1

[0034] Refer to FIGS. 1-2, which show the working flow of an energy-saving air conditioner, comprising an ice container storing ice cubes and ice water, a refrigeration element that exchanges energy with the ice container, and a speed adjustable electric water pump 35 which outputs circular cold water to the air and cold water heat exchanger 39. When indoor air enters the water evaporative cooler, it will flow through the surface gaps of the wet curtain 40 wetted by the principle of capillary water absorption, thereby absorbing the water evaporated from the wet curtain 40, and cooling the air flowing therethrough. The cooled air is divided into two flows. One flow is sucked into the heat exchanger 39 through the speed regulating blowing fan 38 to further cool the air flowing through the heat exchanger 39. At the same time, the saturated water in the condensed air forms water points during the cooling process, and flows into the water storage container of the water evaporative cooler 2, increasing its cooling effect. The other flow is moist air output by the water evaporative cooler 2, which is bypassed by the heat exchanger 39 by a small speed adjustable electric exhaust fan 41, and enters the speed adjustable blowing fan 38 that outputs cold air. The above two flows of cold air drawn in the speed adjustable blowing fan 38 and mixed in the speed adjustable blowing fan 38 are output to the space where the user is located. A temperature and humidity measuring element is provided at the outlet, and the value is returned to the built-in control electronic component to regulate the temperature and humidity of the air output by the air conditioner.

Embodiment 2

[0035] Refer to FIGS. 3-5, which show the internal structure of an energy-saving air conditioner, comprising a conditioner housing 11, a housing top cover 12, a thermal insulation box 16, a thermal insulation box cover 17, a water feed port 18 provided on the thermal insulation box cover, and a water evaporative cooler housing 13, and further comprising an ice container 14 installed in the thermal insulation box 16 and designed to store ice cubes and ice water, a refrigeration element installed in the conditioner housing 11 for energy exchange, a speed adjustable electric water pump 35 provided in a housing of the water evaporative cooler 2, and a built-in intelligent electronic controller (not shown in the figure). The speed adjustable electric water pump 35 for conveying ice water in the air conditioner, the small speed adjustable electric exhaust fan 41 in the water evaporative cooler, and the speed adjustable blowing fan 38 where the cold air is conveyed to the outside of the conditioner can be adjusted by a preset microcomputer programming solution. Within the temperature set by the user and the predetermined humidity range of the air conditioner, the energy-saving effect is improved and the use time of cold storage ice cubes is extended. The speed adjustable electric water pump 35 and the heat exchanger 39 of the ice container 14 are connected to cool the air flowing therethrough. The water absorption wet curtain 40 of the evaporative cooler increases the humidity of the air flowing therethrough. The speed adjustable electric blowing fan 38 is provided. The refrigeration elements comprise a refrigeration compressor 31 and a refrigerant condenser 32 connected to the refrigeration compressor 31, a refrigerant evaporator 33 installed in the refrigeration container 14 and connected to the refrigerant condenser 32, and a heat-transfer evaporator metal sheet 34. The design of ice cube energy storage is used. When the cold air is not used for output, the compressor refrigeration system is turned on to make ice cubes, which are stored in the thermal insulation box 16. When the cold air is used for output, the compressor refrigeration system is turned off, and only the ice cubes stored in the thermal insulation box 16 are used to make cold air, which is output to the space in combination with water evaporation and refrigeration. This product can also be designed as a wall-mounted type or floor-mounted type. The floor-mounted type can add a pulley to the bottom to facilitate movement to a suitable position.

[0036] Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
