Problems solved by technology

The phase change energy tower adopts the phase change heat exchange scheme in the closed energy tower to improve the heat exchange effect and reduce the system operating cost; it does have a certain effect in practice, but it is useless to fully maximize the heat exchange effect. Therefore, on the basis of the application scheme, how to further improve the heat exchange efficiency of the energy tower is a technical problem worth considering

Embodiment 1

[0033] Such as figure 1 The design idea and structure of an energy tower shown in this technical scheme are roughly the same as the implementation scheme of a phase change energy tower and its heat exchange method described in the Chinese invention patent with the publication number CN110360852A previously applied. For details, please refer to The content of the patent application document is different in that the heat exchange tube in the previous energy tower is changed to further improve its heat exchange efficiency, as follows:

[0034] The energy tower includes a tower body 1, which is provided with a heat exchange assembly for sealing and conveying refrigerant, and a spray system using a phase change medium as a fluid; the spray system includes a heat exchange assembly The sprayer 17 above and the spraying direction is toward the heat exchange tube, and the liquid storage tank 12 arranged below the heat exchange assembly for receiving the phase change medium; the liquid stor...

Embodiment 2

[0052] This embodiment is a heat pump system based on the energy tower in Embodiment 1. Therefore, this embodiment adopts the specific energy tower in Embodiment 1 for implementation. Specifically, the heat pump system includes the energy tower described in Embodiment 1 and a closed refrigerant circulating circuit, the heat exchange assembly is connected to the closed refrigerant circulating circuit, and the closed refrigerant circulating circuit further includes a heat exchanger 21, The heat exchange direction of the refrigerant in the heat exchanger 21 is opposite to that in the heat exchange tube of the energy tower.

[0053] The liquid collecting pipe 6 is the liquid inlet and outlet ends, and the gas collecting pipe 5 is the gas inlet and outlet ends; the refrigerant cycle closed circuit also includes a compressor 22, a throttling device 23, and an oil separator 24. The compressor 22 and the oil separator 24 , The gas collecting pipe 5, the liquid collecting pipe 6, the thro...

Embodiment 3

[0055] This embodiment is based on the heat exchange method adopted in the heat pump system with energy tower in the second embodiment, so this embodiment adopts the heat pump system in the above-mentioned embodiment 2 for implementation. For specific details, please refer to the applicant's description of the implementation scheme of a phase-change energy tower and its heat exchange method in the Chinese invention patent with publication number CN110360852A, which will not be repeated here.

[0056] Summer mode (e.g. figure 2 Shown): The refrigerant gas is compressed by the compressor 22 and then enters the oil separator 24 for oil separation, flows through the four-way valve 25, and then the refrigerant gas enters the gas collecting pipe 5; the spray system runs, and the phase change medium passes through the sprayer 17 Sprayed on the surface of the heat exchange plate 2, the phase change medium forms a water film on the surface of the heat exchange plate 2, and absorbs heat th...

Abstract

The invention relates to the field of heat exchange equipment, in particular to an energy tower and a heat pump system thereof. A heat exchange assembly for sealed conveying of a refrigerant is arranged in a tower body, and a phase change medium is used as a liquid spraying system; the spraying system comprises a spraying machine of which the spraying direction faces a heat exchange pipe, arrangedon the heat exchange assembly, and a liquid storage tank which is arranged below the heat exchange assembly and used for bearing a phase change medium; the heat exchange assembly comprises an air collecting pipe, a liquid collecting pipe and a plurality of heat exchange plates which are arranged between the air collecting pipe and the liquid collecting pipe and are arrayed and arrayed in an equalspacing manner; the liquid storage tank communicates with the spraying machine through a pipeline; one or more precooling heat exchangers located in the tower body are arranged on the pipeline; and the phase change medium sprayed from the spraying machine and the refrigerant in the heat exchange plates are in heat exchange in the manner of a part evaporation or condensing manner, and the heat exchange effect is increased.

Description

Technical field [0001] The invention relates to the field of heat exchange equipment, in particular to an energy tower and a heat pump system thereof. Background technique [0002] At present, the energy consumption of buildings in our country is very huge, and the proportion of building energy consumption currently accounts for about 27.5% of the terminal energy consumption of the whole society. And with the development of urbanization, the energy consumption of buildings will increase rapidly, and the development of urbanization has put greater pressure on the energy supply of building energy in my country. Air-conditioning energy consumption accounts for about 30% of building energy consumption. Improving the efficiency of air-conditioning systems is of great significance for energy saving and emission reduction. [0003] In my country’s hot summer and cold winter areas, because there is no central heating in this area in winter, most buildings use electricity or air source hea...
