Background
The condensing system is an important component part in the aspects of refrigeration and air conditioning, and is an important heat exchange device for the outward heat release of the refrigerating system and the realization of the phase state reduction of the refrigerant. Its main function is to transfer the heat of high-temp. and-pressure refrigerant vapour discharged from compressor to cooling medium to cool and liquefy the refrigerant vapour. The energy of the refrigerant is transferred with the medium outside the condenser, and the economical efficiency and the reliability of the operation of the refrigerating device are directly influenced by the performance of the refrigerating device. The refrigerant is cooled into dry saturated vapor by superheated vapor in the condenser, moist heat is released, and then the dry saturated vapor is condensed into saturated liquid, and a large amount of latent heat is released. If the saturated liquid is cooled continuously, the saturated liquid becomes a supercooled liquid.

Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are shown in the drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.
As shown in fig. 1, a water-cooled staged cooling and condensing system in a well comprises: cooling water well group 100, condenser pipe 200, compressor 300, water stop valve 400, expansion valve 500 and evaporator 600. Wherein the evaporator 600 is connected to the compressor 300; the condensation duct 200 is connected between the water outlet of the compressor 300 and the water inlet of the evaporator 600; the cooling water well group 100 comprises at least one cooling water well 110, and the condensation pipe 200 extends into each cooling water well 110 along the inner wall of each cooling water well 110; a water stop valve 400 and an expansion valve 500 are sequentially provided on the condensation pipe 200 between the cooling water well group 100 and the evaporator 600.
In this embodiment, adopt the cooling water well group including at least one cooling water well to carry out water-cooled cooling condensation, ensure under the condition that does not need the water pump, realize water-cooled condensation, it is more economical and practical.
Specifically, one end of the condensation pipe 200 is connected to a water outlet of the compressor 300, and then sequentially extends into the cooling water well 110. After the cooling water well 110 comes out, a water stop valve 400 is installed on the condensation pipe 200, and then the condensation pipe 200 is connected to an expansion valve 500, passes through the expansion valve 500, and is connected to an evaporator 600. The outlet of the evaporator 600 is connected with the inlet of the compressor 300, which forms a large-scale refrigerating device using the water-cooled sectional cooling and condensing system in the well. When the water stop valve 400 is opened, the gaseous refrigerant in the compressor 300 passes through the condensation pipe 200 and is condensed by the cooling water well group 100, i.e., is cooled by the cooling water wells 110 in sections. The cooled refrigerant becomes liquid and enters the expansion valve 500 to be cooled.
It can be understood that the compressor 300 pressurizes the low-pressure gaseous refrigerant into a high-pressure liquid refrigerant, and then the high-pressure liquid refrigerant enters the cooling water well group 100 for cooling, after a trace amount of water in the liquid refrigerant is filtered, the low-pressure liquid refrigerant enters the evaporator 600 after passing through the expansion valve 500 with a proper flow rate regulation, and finally returns to the compressor 300 through the low-pressure pipeline.
It should be noted that the expansion valve 500 plays a role in throttling and depressurizing and adjusting the flow rate. On one hand, the expansion valve throttles and depressurizes the liquid refrigerant in the condensation pipe 200 into a low-temperature and low-pressure vapor-liquid mixture which is easy to evaporate, and the mixture enters the evaporator 600, so that the high-pressure side and the low-pressure side of the refrigerant are separated; on the other hand, the expansion valve 500 automatically adjusts the flow rate into the evaporator 600 to a suitable degree required for the refrigeration cycle. In addition, the expansion valve 500 enables the evaporator 600 to have a certain degree of superheat through the adjustment of the flow rate, so that the effective utilization of the total volume of the evaporator 600 is ensured, and the liquid impact caused by the liquid refrigerant entering the compressor 300 is avoided; meanwhile, the superheat degree can be controlled within a certain range, and the abnormal overheating phenomenon is prevented.
In one embodiment, as shown in FIG. 2, the cooling water well group 100 includes four cooling water wells 110.
Specifically, the evaporator 600 is disposed indoors, and the compressor 300 is disposed outdoors.
In one embodiment, the depth of each cooling water well 110 is set to 70 meters.
In one embodiment, as shown in fig. 3, which is an elevation view of an embodiment of the cooling water well 110, each cooling water well 110 comprises at least one rigid polyvinyl chloride (UPVC) well pipe 111, and the rigid polyvinyl chloride well pipes 111 are arranged in a stacked manner.
In one embodiment, referring to FIG. 3, each rigid polyvinyl chloride well pipe 111 is provided with a diameter of 250 millimeters.
In one embodiment, as shown in fig. 3 and 4, the rigid polyvinyl chloride well pipe 111 at the bottommost layer of each cooling water well 110 is provided with heat dissipation holes P. The heat dissipation holes P are arranged 500 mm away from the bottom of the bottommost rigid polyvinyl chloride well pipe 111, and the diameter of each heat dissipation hole P is 100 mm.
In this embodiment, the heat dissipation holes P are disposed around the bottom of the bottom rigid pvc well pipe 111, which is beneficial for heat dissipation and improves the cooling effect of each cooling well 110.
In one embodiment, the distance between the cooling water wells 110 is set to 5 meters.
In one embodiment, the condenser tube 200 comprises at least one segment of brass tube, and the segments of brass tube are connected in series.
In this embodiment, the condensation pipes 200 are assembled in a sectional connection manner. Wherein the condensation duct 200 comprises a straight brass tube and a connector. The brass tube is connected from the water outlet end of the compressor 300, sequentially extends into the well in a series connection mode, then is connected to the water stop valve 400 and the expansion valve 500, and finally is connected to the water inlet end of the evaporator 600.
Specifically, the thickness of the tube wall of each section of brass tube is set to 1 mm, and the diameter of each section of brass tube is set to 10 mm.
It can be understood that the method for using the water-cooled sectional cooling and condensing system in the well is as follows:
firstly, drilling the cooling water well group 100 according to the requirements, and ensuring that the water source of the cooling water well group 100 is normal; secondly, the condenser pipe 200 is assembled and then extends into each cooling well 110, and then the condenser pipe 200 is respectively connected with the compressor 300, the water stop valve 400, the expansion valve 500 and the evaporator 600; and finally, opening a water stop valve 400, and enabling the sectional cooling and condensing system in the water-cooled well to work normally.
In the sectional cooling condensing system in the water-cooled well, the cooling well group 100 comprising at least one cooling well 110 is adopted for water-cooled cooling condensation, so that the water-cooled condensation is realized under the condition that a water pump is not needed, and the sectional cooling condensing system is more economical and practical.
