Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning box units, in particular to an intelligent central air-conditioning unit. Background Art

[0002] The kitchen space is relatively small. In the summer, when people cook, the kitchen environment is very humid and hot, and the human body feels very uncomfortable. However, the existing technology and the market lack special air conditioners designed for kitchen space to solve the problem of poor comfort when people cook in the kitchen. The kitchen is a place that people often need to enter in their daily lives, but there are many heat sources and high humidity in the kitchen. The already hot temperature in summer makes the hot and humid environment in the kitchen even worse, which brings strong discomfort to the cooks. Therefore, the demand for air conditioning in the kitchen environment in summer is increasing day by day.

[0003] Authorization announcement number CN218936534U discloses an intelligent central air-conditioning unit. The overall internal structure of the patented technology is reasonably and simply arranged, and in actual use, the working state is stable, the connection between each unit is tight, and the coordination efficiency is high, it has good processing capacity, the overall structural design is simple, and the control is convenient and fast. Windows are set on the boxes of the primary filter section, the spray section and the high-efficiency filter section to facilitate operators to replace the filter element of the filter device. When the structure in the air-conditioning unit fails, it is also convenient to check and repair, which provides convenience for operators who overhaul the combined air-conditioning unit; however, in the steam compression refrigeration system in this scheme, the compressed Freon vapor is in a high-pressure and high-temperature overheated state. Due to its fast flow rate and high temperature when it is discharged, part of the lubricating oil on the compressor cylinder wall will inevitably become oil vapor and oil droplets due to the high temperature and be discharged together with the refrigerant vapor. Moreover, the higher the exhaust temperature and the faster the flow rate, the more lubricating oil is discharged. If this state lasts for a long time, the oil in the compressor will become less and less, and finally the compressor will be short of oil, which will lead to the failure of the compressor burning oil. In addition, the drainage and water intake of the water outlet pipe of the central air-conditioning unit are relatively weak, which reduces the working efficiency of the central air-conditioning unit. Therefore, an intelligent central air-conditioning unit is needed to improve the above problems. Utility Model Content

[0004] In order to solve the problem in the existing scheme that in the steam compression refrigeration system, the compressed Freon steam is in a high-pressure and high-temperature overheated state. Due to the fast flow rate and high temperature when it is discharged, part of the lubricating oil on the cylinder wall of the compressor will inevitably become oil vapor and oil droplets due to the high temperature and be discharged together with the refrigerant steam. And the higher the exhaust temperature and the faster the flow rate, the more lubricating oil will be discharged. If this state lasts for a long time, the oil in the compressor will become less and less, and finally the compressor will be short of oil, which will cause the compressor to burn oil. In addition, the drainage and water intake of the water outlet pipe of the central air-conditioning unit are relatively small, which reduces the working efficiency of the central air-conditioning unit. The purpose of this utility model is to provide an intelligent central air-conditioning unit to solve the problems raised in the above background technology.

The top of the second support bracket 301 is fixedly connected with a frequency converter box 306. The oil separator 210 is used to separate the lubricating oil from the compressor 206 and the high-pressure gaseous refrigerant mixture. The oil separator 210 can separate the refrigerant and the lubricating oil. The exhaust port of the compressor 206 discharges high-temperature and high-pressure gas, which is actually a mixture of refrigerant and refrigeration oil. If the refrigerant enters the pipeline system and is mixed with too much refrigeration oil, the heat exchange efficiency of the evaporator 302 and the condenser 202 will be reduced, and the compressor 206 will easily be damaged due to lack of oil. Therefore, the use of the oil separator 210 is crucial to the normal oil supply of the compressor 206.

[0027] Among them, the side of the condenser 202 is fixedly connected with a refrigerated water inlet pipe 203 and a refrigerated water outlet pipe 205, and the tops of the refrigerated water inlet pipe 203 and the refrigerated water outlet pipe 205 are fixedly connected with a first water pump 204. The side of the evaporator 302 is fixedly connected with a cooling water inlet pipe 303 and a cooling water outlet pipe 304, and the tops of the cooling water inlet pipe 303 and the cooling water outlet pipe 304 are fixedly connected with a second water pump 305. The side of the frequency converter box 306 is fixedly connected with a knob switch 307 and a display 308. The side of the frequency converter box 306 is fixedly connected with a power indicator light 309 and a lighted button 310. There are three lighted buttons 310. The first water pump 204 and the second water pump 305 are used to transport chilled water and cooling water or pressurize the liquid, and the mechanical energy of the prime mover or other external energy is transmitted to the liquid to increase the energy of the liquid. The first water pump 204 and the second water pump 305 work stably, the transportation is continuous, and the flow and pressure are pulsating, thereby enhancing the working performance of the central air-conditioning unit.

[0028] In this embodiment, refer to Figure 1 and Figure 4 As shown, the support assembly 1 includes a carrier frame 101, a loading plate 103 is fixedly connected to the top of the carrier frame 101, a moisture-proof pad 102 is fixedly connected to the bottom of the carrier frame 101, and two moisture-proof pads 102 are provided. The moisture-proof pads 102 can ensure that the support assembly 1 is not corroded by moisture, thereby further improving the service life of the support assembly 1.

[0029] In the present scheme, when an intelligent central air-conditioning unit is in use, first, a low-pressure gaseous refrigerant is pressurized by the compressor 206 and enters the condenser 202 and gradually condenses into a high-pressure liquid. During the condensation process, the refrigerant releases a large amount of heat energy, which is absorbed by the cooling water in the condenser 202 and sent to the outdoor cooling tower, and finally released into the atmosphere. During the process, the oil separator 210 is used to separate the lubricating oil coming out of the compressor 206 from the high-pressure gaseous refrigerant mixture, thereby increasing the heat exchange efficiency of the evaporator 302 and the condenser 202, and avoiding damage to the compressor 206 due to lack of oil.
