Description

Technical Field

[0001] This invention relates to the field of heat pump air conditioning for heat source towers, and in particular to a water distributor applied to the outdoor platform of a heat source tower. Background Technology

[0002] Currently, central air conditioning systems used in China can be classified according to their heat source and cold source, including heat pump systems, single-cooling-unit + boiler systems, and direct-fired air conditioning systems. Heat pump systems can be further divided into water source heat pump systems, ground source heat pump systems, and air source heat pump systems. These various types of heat pump systems are widely used. In recent years, a new type of hybrid heat pump system has emerged: the heat source tower heat pump system.

[0003] The heat source tower heat pump air conditioning system utilizes the cooling tower—the summer cold source—of the original single-cooling unit + boiler air conditioning system. After modification, it is called the outdoor platform of the heat source tower, which serves as a heat dissipation tower in summer and a heat absorption tower in winter. The original single-cooling unit is replaced with a low-temperature water source heat pump unit, which is used in conjunction with the outdoor platform of the heat source tower to provide cooling in summer and heating in winter. At the same time, the boiler in the original system is removed and no longer needed. This achieves the goal of providing air conditioning and heating through a single system all year round, eliminating the need to use fossil fuels for heating. Therefore, it has been widely promoted and used in the middle and lower reaches of the Yangtze River in my country, especially in areas with hot summers and cold winters.

[0004] In summer, the cooling water in the outdoor platform of the heat source tower heat pump air conditioning system comes into contact with the outdoor air. Since the temperature of the cooling water is generally 35℃ to 37℃, it will be higher than the wet-bulb temperature or dry-bulb temperature of the outdoor air during the contact process. As a result, the cooling water will exchange heat and mass with the outdoor air. Some of the heat is dissipated through heat exchange, and the other part of the heat is dissipated through the evaporation of the cooling water. During the heat exchange process, the temperature of the cooling water gradually decreases, thereby achieving the purpose of cooling.

[0005] In winter, the low-temperature antifreeze in the outdoor platform of the heat source tower heat pump air conditioning system comes into contact with the outdoor air. Since the temperature of the antifreeze is generally 0℃ to -10℃, this temperature will be lower than the dry bulb temperature or dew point temperature of the outdoor air during the contact process. As a result, the antifreeze will undergo heat and mass exchange with the outdoor air. Some of the heat will enter the antifreeze through heat exchange, and the other part of the heat will enter the antifreeze through the release of latent heat from the condensation of water vapor in the air. During the heat exchange process, the temperature of the antifreeze gradually rises, thereby achieving the purpose of heating.

[0006] In the aforementioned heat exchange process, the amount of heat required for exchange differs between summer and winter. Furthermore, the different operating conditions of the outdoor platform of the heat source tower result in different flow rates of cooling water and antifreeze entering the platform (antifreeze flow rate is generally 50-70% of cooling water flow rate). Currently, the selection of the outdoor platform for the heat source tower is generally based on the summer cooling water flow rate. However, the summer cooling water flow rate is much greater than the winter antifreeze flow rate. This leads to uneven distribution of antifreeze within the outdoor platform in winter, a smaller increase in antifreeze temperature, deterioration of heat exchange effect, and a decrease in heat exchange capacity. This further reduces the heating efficiency of the low-temperature water source heat pump unit in winter, thereby lowering the overall winter heating efficiency. Therefore, solving these problems has become a research direction for those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide a water distributor for use on the outdoor platform of a heat source tower, so as to solve the problems mentioned in the above-mentioned technical background.

[0008] The objective of this invention is achieved through the following technical solution:

[0009] A water distributor for an outdoor platform of a heat source tower includes a base plate and a surrounding plate disposed on the base plate. A receiving chamber is formed between the surrounding plate and the base plate. A partition is provided in the receiving chamber, dividing the receiving chamber into a first receiving chamber and a second receiving chamber. The first receiving chamber has a winter water distribution hole penetrating the partition and the base plate. The second receiving chamber has a summer water distribution hole disposed on the surface of the base plate. The water flow rate of the summer water distribution hole is greater than that of the winter water distribution hole.

[0010] Furthermore, the enclosure is further provided with a winter water supply pipe and a summer water supply pipe that are respectively connected to the first accommodating chamber and the second accommodating chamber.

[0011] Furthermore, in the above-described invention, the partition is composed of a horizontal plate and an inclined plate, and the water distribution hole is located on the horizontal plate during winter.

[0012] Furthermore, in the above-described invention, the base plate is a rectangular plate, and the surrounding plate is disposed on the perimeter of the rectangular plate.

[0013] Furthermore, in the above-mentioned invention, the winter water distribution hole includes a plurality of winter water distribution holes, and the summer water distribution hole includes a plurality of summer water distribution holes, wherein the plurality of winter water distribution holes and the plurality of summer water distribution holes are respectively distributed in the first accommodating chamber and the second accommodating chamber.

[0014] Furthermore, in the above-mentioned invention, the inner diameters of the winter water distribution holes and the summer water distribution holes are the same, and the number of summer water distribution holes is greater than the number of winter water distribution holes.

[0015] Furthermore, in the above-mentioned invention, the number of water distribution holes in winter is 50%-70% of the number of water distribution holes in summer.

[0016] The beneficial effects of this invention are as follows: This invention is provided with a first receiving chamber and a second receiving chamber, and the water flow rates of the first receiving chamber and the second receiving chamber are different, so as to meet the different requirements of the outdoor platform of the heat source tower heat pump air conditioner for circulating water in winter and summer. In winter, antifreeze can enter the heat exchange packing of the outdoor platform of the heat source tower through the winter water distribution hole of the first receiving chamber for heat exchange. In summer, cooling water can enter the heat exchange packing of the outdoor platform of the heat source tower through the summer water distribution hole of the second receiving chamber for heat exchange. Through the above configuration, the different flow rate requirements of antifreeze and cooling water of the heat source tower heat pump air conditioner in winter and summer can be met, thereby achieving uniform and stable water distribution on the outdoor platform, and achieving the goal of efficient operation of the outdoor platform of the heat source tower heat pump air conditioner in both winter and summer.

[0022] Example:

[0023] A water distributor for use on the outdoor platform of a heat source tower; please refer to the appendix. Figure 1 and attached Figure 2 As shown, it includes a base plate 1 and a surrounding plate 2 disposed on the base plate. Specifically, the base plate 1 is a rectangular plate, and the surrounding plate 2 is disposed on the perimeter of the rectangular plate. The surrounding plate 2 and the base plate 1 form a receiving chamber 3. The receiving chamber 3 is provided with a partition 4, which divides the receiving chamber into a first receiving chamber 3.1 and a second receiving chamber 3.2. The first receiving chamber 3.1 is provided with a winter water distribution hole 5 that penetrates the partition 4 and the base plate 1. The second receiving chamber 3.2 is provided with a summer water distribution hole 6 disposed on the surface of the base plate 1. The water flow rate of the summer water distribution hole 6 is greater than that of the winter water distribution hole 5.

[0024] In the application of this invention, when the heat pump air conditioner is in summer operation, cooling water flows into the outdoor platform of the heat source tower through the summer water distribution hole 6 in the second receiving chamber 3.2 for heat exchange. When the heat pump air conditioner is in winter operation, antifreeze flows into the outdoor platform of the heat source tower through the winter water distribution hole 5 in the first receiving chamber 3.1 for heat exchange. Since the flow rate of the summer water distribution hole 6 is greater than that of the winter water distribution hole 5, it can meet the requirement of lower antifreeze flow rate of the heat pump air conditioner in winter, thereby achieving uniform and stable water distribution on the outdoor platform of the heat source tower, and achieving the goal of efficient operation of the outdoor platform of the heat pump air conditioner in both winter and summer. It should be noted that the enclosure 2 is also equipped with a winter water supply pipe 7 and a summer water supply pipe 8, which are respectively connected to the first receiving chamber 3.1 and the second receiving chamber 3.2. In winter, antifreeze can flow into the first receiving chamber 3.1 through the winter water supply pipe 7, while in summer, cooling water can flow into the second receiving chamber 3.2 through the summer water supply pipe 8.

[0025] In the above embodiments, preferably, the partition 4 is composed of a horizontal plate 4.1 and an inclined plate 4.2, and the water distribution hole 5 is provided on the horizontal plate 4.1 in winter.

[0026] In the above embodiments, preferably, the winter water distribution hole 5 includes multiple winter water distribution holes, and the summer water distribution hole 6 includes multiple summer water distribution holes. The multiple winter water distribution holes 5 and the multiple summer water distribution holes 6 are evenly distributed in the first receiving chamber 3.1 and the second receiving chamber 3.2, respectively. The inner diameters of the winter water distribution holes 5 and the summer water distribution holes 6 are the same, and the number of summer water distribution holes 6 is greater than the number of winter water distribution holes 5. Specifically, considering that the antifreeze flow rate is generally 50%-70% of the cooling water flow rate in winter and summer, in this embodiment, the number of winter water distribution holes 5 is set to 50%-70% of the number of summer water distribution holes 6.

[0027] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
