Description

TECHNICAL FIELD

[0001] The utility model relates to cold water machine technical field, concretely is a cold water machine with high -efficient circulating filter system. BACKGROUND

[0002] In the key fields such as industrial production, data center cooling and commercial refrigeration, the cold water machine plays an indispensable role. As the core equipment of the refrigeration system, the performance and stability of the cold water machine are directly related to the operation efficiency and safety of the whole system. However, the design of the traditional cold water machine, especially the single compression system and single compressor configuration, gradually reveals its limitations and deficiencies when facing complex and variable operating environments and high load work demands.

[0003] The traditional cold water machine often adopts a single compression system. Although this design can meet the basic refrigeration requirements to some extent, it faces many challenges in actual application. On the one hand, the single compression system lacks redundancy and backup mechanism, and once a fault occurs, the entire cold water machine system may be shut down, which not only seriously affects production efficiency, but also may pose a threat to data security, and the internal filtering performance is also invalid at the same time. On the other hand, in the face of high load work demand, the single compression system often has difficulty in maintaining long-term stable operation, and its stability and reliability are therefore greatly discounted.

[0004] In addition, the traditional single compressor is prone to overload, wear and tear and other faults under long-term high load operation, which not only shortens the service life of the compressor, but also causes the refrigeration efficiency to drop significantly. INVENTION CONTENTS

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] As Figs. 1-3 Indicated, the utility model provides a kind of cold water machine with high-efficiency circulation filter system, its structure mainly includes compressor body, condenser 3 and evaporator 4, and compressor body is divided into two independent working parts again: first compressor 1 and second compressor 2. Two compressors are connected with condenser 3 and evaporator 4 after being respectively, and two independent compression systems are formed, independently run, improve the refrigeration efficiency of entire cold water machine and the reliability of operation. When operating, the compression system of first compressor 1 is operated first, and the compression system of second compressor 2 can stop operating or operate synchronously with the compression system of first compressor 1, to adjust the refrigeration effect of whole.

[0026] Two independent compression systems, both share a condenser 3 and an evaporator 4. Therefore, two independent condensing channels (first condensing channel 301 and second condensing channel 302) are provided in the condenser 3, both of which are hidden inside the condenser 3, and each condensing channel is provided with an inlet and an outlet. At the same time, two independent evaporation channels (first evaporation channel 401 and second evaporation channel 402) are provided in the evaporator 4, both of which are hidden inside the evaporator 4, and each evaporation channel is provided with an inlet and an outlet. In addition, two first compressors 1 / second compressors 2 are used in the two compression systems, and each system works through two compressors, which can improve the refrigeration efficiency and meet the demand of large load.

[0027] First compressor system: The output ends of the two first compressors 1 are connected to the inlet of the first condensing channel 301 through pipes. This design can ensure that the compressed gas generated by the two compressors can enter the first condensing channel 301 for condensation uniformly. The outlet of the first condensing channel 301 is connected to the inlet of the first evaporation channel 401 through the first expansion valve 5 and the first filter 6 in turn. The outlet of the first evaporation channel 401 is connected back to the input end of one of the first compressors 1 in a closed loop, forming a complete refrigeration cycle.

[0028] Second compressor system: Similar to the first compressor system, the output ends of the two second compressors 2 are connected to the inlet of the second condensing channel 302. The outlet of the second condensing channel 302 is connected to the inlet of the second evaporation channel 402 through the second expansion valve 7 and the second filter 8 in turn. The outlet of the second evaporation channel 402 is connected back to the input end of one of the second compressors 2 in a closed loop, forming a second independent refrigeration cycle.

[0029] In the second compressor system, a control valve 9 is additionally provided between the outlet of the second condensing channel 302 and the inlet of the second evaporation channel 402. This control valve 9 can be used to adjust the flow of refrigerant entering the second evaporation channel 402, thereby achieving fine control of the overall refrigeration effect.

[0030] In addition, in order to facilitate the injection of chilled water into the evaporator, chilled water injection ports 403 are provided on both sides of the evaporator 4, one of which is equipped with a detachable sealing cover 404 for easy maintenance and operation. In use, the user can select one of the chilled water injection ports 403 to inject chilled water according to the actual use, and the other chilled water injection port 403 needs to be sealed with the sealing cover 404. When the evaporator 4 needs to be maintained, the maintenance can be carried out by opening both sides of the chilled water injection ports 403 at the same time, which is convenient to operate.

[0031] The condenser 3 is provided with a cooling medium injection port 303 and a cooling medium discharge port 304 for injecting and discharging cooling medium to carry away the heat generated during condensation.

The rack 10 is also provided with an electric control box 11 for controlling the power supply of the entire water chiller, including starting, stopping and fault monitoring functions.

[0033] Compared with the prior art, the water chiller provided by the technical scheme sets two independent compression systems, realizes efficient and flexible refrigeration circulation and filtration, so that each system can work independently and does not affect each other, thereby greatly enhancing the stability and reliability of the water chiller and the filtration effect. When one of the systems fails, the other system can still operate normally, ensuring the continuous working ability of the water chiller and avoiding the risk of overall shutdown due to single system failure. In addition, two compressors are arranged in each compression system, which further improves the performance and reliability of the water chiller. The two compressors in each system work together to share the load, reduce the operating pressure of the single compressor, prolong the service life of the compressor, improve the refrigeration capacity of the system, and enable the water chiller to reach the set temperature faster. When one of the compressors needs to be maintained or repaired, the other compressor can still maintain the basic operation of the system, ensuring the continuity and stability of the water chiller.
