DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects of the utility model easier to understand, the utility model is further described below in conjunction with specific embodiments.

[0027] In the description of the present invention, it should be understood that the terms "lateral", "longitudinal", "end", "edge", "sidewall", "up", "down", "upper part", "lower part", "directly above", "surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential", "end", "head" and "tail" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the technical solution of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] In order to further improve work efficiency, this application proposes a high-efficiency cooling tower equipment, which is as follows:

[0029] For reference Figure 1 The present application is mainly composed of a tower body divided into a circulation area 11 and a recovery area 12; the refrigerant gas generated in the circulation area 11 is blown into the recovery area 12 to promote the near wind stability of the cooling tower to be lower.

[0030] For reference Figure 1 A heat pump evaporator 101, a heat pump condenser 102 and a blower 103 are provided in the circulation area 11; the heat pump evaporator 101 is arranged at the bottom of the circulation area 11, and the heat pump condenser 102 is located on the upper side of the heat pump evaporator 101 and is arranged in the heat pump evaporator 101; wherein, the pipeline for the flow of refrigerant gas in the heat pump condenser 102 is arranged obliquely along the inner cavity of the circulation area 11; the air outlet of the blower 103 is arranged in the inner cavity of the circulation area 11, wherein a place where the pipeline of the heat pump condenser 102 is inclined is opposite to the air outlet of the blower 103.

[0031] Therefore, when the blower 103 moves, the pipe for the flow of refrigerant gas in the heat pump condenser 102 is blown toward the recovery area 12, further reducing the problems of low efficiency and poor refrigeration effect in the recovery area 12 due to high temperature weather.

[0032] Furthermore, a cycle is formed between the heat pump evaporator 101 and the heat pump condenser 102 through a compressor and an expansion valve, realizing the working form of the reverse Carnot cycle principle; the connection setting is an existing structure.

[0033] The specific implementation is as follows: the heat pump evaporator 101 and the compressor are connected by a pipeline. After the refrigerant absorbs heat from the external environment in the evaporator, it enters the compressor in a gaseous form. This pipeline is mainly used to send the gaseous refrigerant from the heat pump evaporator 101 to the compressor so that the compressor can perform compression processing. The compressor and the heat pump condenser 102 are also connected by a pipeline; the compressor sends the compressed high-temperature and high-pressure refrigerant to the heat pump condenser 102; in the heat pump condenser 102, the refrigerant releases heat and cools, thereby becoming liquid. The heat pump condenser 102 and the expansion valve are also connected by a pipeline. The condensed liquid refrigerant flows from the heat pump condenser 102 to the expansion valve; this pipeline is used to send the condensed liquid refrigerant to the expansion valve so that it can enter the heat pump evaporator 101 on the low-pressure side through the expansion valve. The expansion valve and the heat pump evaporator 101 are also connected by a pipeline. Through the expansion valve, the refrigerant is placed from the high-pressure liquid state into the heat pump evaporator 101 on the low-pressure side, thereby completing the closed loop of the refrigerant cycle.

[0034] For reference Figure 2-3 A reflux port 14 connected to the recovery area 12 is provided at the inclined end of the refrigerant gas flow pipe near the heat pump condenser 102 in the circulation area 11, so that the condensed water generated by the heat pump evaporator 101 can be returned to the recovery area 12, saving water resources.

[0035] At the same time, the recovery area 12 discharges the heat accumulated in the hot water or other cooling medium into the atmosphere from the air outlet 13 arranged at the top, and when the source heat pump evaporator 101 is working, it will absorb the heat discharged from the recovery area 12, thereby greatly improving the heating capacity of the air source heat pump.

[0036] For reference Figure 2-3 A water tank 121, a water level stabilizing mechanism 122 and a filler 123 are provided in the recovery area 12; the water tank 121 is provided in the recovery area 12 for receiving condensed water converted from gas; the water level stabilizing mechanism 122 is provided on the water tank 121 for maintaining the water level stability in the water tank 121; the filler 123 is provided in the water tank 121, and the position of the filler 123 is located on the upper side of the pipe inclined on the heat pump condenser 102 for the flow of refrigerant gas; therefore, when the blower 103 synchronously blows the cold air on the pipe for the flow of refrigerant gas into the water tank 121 and then passes through the filler 123, the cooling efficiency can be further improved.

[0037] The water level stabilizing mechanism 122 for maintaining water level balance inside the water tank 121 is mainly composed of a float valve 1221 and a conveying member 1222; the float valve 1221 is located on the lower side of the filler 123 and is arranged on the water tank 121, and the conveying member 1222 is arranged on the water tank 121, and the float valve 1221 controls the conveying member 1222 to stabilize the condensed water in the water tank 121.

[0038] The opening and closing of the valve is controlled by the floating ball, thereby adjusting the water flow into or out of the cooling tower; when the water level drops to a certain level, the float sinks, opens the conveying member 1222, and allows water to flow into the cooling tower. When the water level rises to a certain level, the float floats up, closes the conveying member 1222, and stops the water from flowing into the cooling tower. The function of the float valve is to automatically adjust the water flow according to the water level change and maintain the water level within a suitable range.

[0039] The conveying member 1222 is composed of a refrigerated water inlet pipe 21, a cooling water outlet pipe 22 and a water supply pipe 23; the refrigerated water inlet pipe 21 is located on the upper side of the filler 123 and is arranged on the water tank 121; the cooling water outlet pipe 22 is located on the lower side of the float valve 1221 and is arranged on the water tank 121; the two ends of the water supply pipe 23 are respectively connected to the refrigerated water inlet pipe 21 and the cooling water outlet pipe 22; and a solenoid valve 24 compatible with the float valve 1221 is provided on the refrigerated water inlet pipe 21, the cooling water outlet pipe 22 and the water supply pipe 23.

[0040] When the float valve 1221 detects water level changes, it controls the solenoid valve 24 of the freezing water inlet pipe 21 to allow water to enter, or the solenoid valve 24 of the cooling water outlet pipe 22 to allow water to exit, and the solenoid valve 24 of the water replenishment pipe 23 to replenish water, so as to maintain the horizontal balance in the water tank 121.

[0041] In the utility model, the working steps of the device are as follows:

[0042] 1. First, the heat pump evaporator 101 absorbs heat from the external environment and changes the refrigerant from liquid to gas; the refrigerant gas is compressed by the compressor to increase its temperature and pressure; it enters the heat pump condenser 102 to cool the high-temperature and high-pressure refrigerant compressed by the compressor into liquid, and the expansion valve allows the high-pressure liquid refrigerant to enter the heat pump evaporator 101 on the low-pressure side from the heat pump condenser 102, completing the closed loop of the refrigerant cycle;

[0043] 2. Secondly, during the circulation process, the heat pump condenser 102, through which the refrigerant gas flows, emits cold air, and the blower 103 blows the cold air into the water tank 121;

[0044] 3. Then, during the next period, the heat pump evaporator 101 can discharge condensed water from the reflux port 14 into the water tank 121;

[0045] 4. Finally, the movement of the blower 103 lowers the air inlet temperature in the recovery area 12, and at the same time, the water level stabilizing mechanism 122 maintains the height of the water level in the inner water tank 121 to maintain the balance of the inner water level.

Those skilled in the art should understand that the utility model is not limited to the above embodiments.
