Description

Technical Field

[0001] The utility model relates to the technical field of water chillers, in particular to an integrated screw water chiller. Background Art

[0002] Integrated screw chillers have many features such as efficient integration, water and electricity saving, no need for machine room, unattended operation, and quick installation, and are increasingly accepted and recognized by the market. Integrated screw chillers are usually installed outdoors. In the hot summer, the ambient temperature is as high as 30°C, and the internal temperature of the integrated screw chiller may reach 50°C-60°C. If it is operated in such a high temperature environment for a long time, the components in the integrated screw chiller will be damaged due to high load operation and overheating, which will cause the integrated screw chiller to fail to operate normally.

[0003] At present, in order to improve the reliability of the integrated screw chillers on the market, cooling fans are often installed on the shell of the integrated screw chillers. However, different integrated screw chillers have different internal space sizes, and the installed cooling fans also need to be selected according to the space size of the integrated screw chillers. If the air volume is too small, the cooling fan will not only fail to extract the internal heat to the outside, but may also cause the cooling fan to overload and burn out; if the air volume is too large, the cooling fan will increase the power consumption of the integrated screw chiller and reduce the energy efficiency of the whole machine. In addition, if there are too many cooling fans, it may lead to increased costs. If all the cooling fans are installed on the cabinet board of the integrated screw chiller, the holes on the cabinet board are too dense, which affects the appearance of the unit.

[0032] In this way, by providing a connecting channel and ventilation louvers 31, the ventilation louvers 31 can be opened as needed to connect the connecting channel, thereby enabling the cooling tower 1 to connect with the chiller body 2, and then utilizing the condensing fan 22 to extract and discharge the heat in the chiller body 2, thereby achieving cooling of the inside of the chiller body 2, ensuring that the inside of the chiller body 2 can be at room temperature, and enabling the electrical components in the chiller body 2 to operate reliably; compared with the existing integrated screw chiller, the utility model does not add multiple cooling fans, reduces the cost of the integrated screw chiller, and can also reduce the power consumption of the entire integrated screw chiller, thereby improving the efficiency of the integrated The energy efficiency of the integrated screw chiller is improved, and the heat dissipation component 3 and the temperature detection component 4 are both located in the chiller body 2, and the connecting channel is also arranged in the cooling tower 1 and the chiller body 2, which beautifies the appearance of the integrated screw chiller; by arranging the temperature detection component 4, the temperature in the chiller body 2 can be detected in real time, so as to cool down the inside of the chiller body 2 in time; by setting the driving component 32 and the temperature detection component 4 to communicate with the controller, so that the temperature detected by the temperature detection component 4 can be transmitted to the controller, and the controller controls the driving component 32 to drive the ventilation shutters 31 to open or close according to the temperature, so that the connecting channel is connected or disconnected, so as to realize cooling of the inside of the chiller body 2.

[0033] It should be noted that, in this embodiment, the inventor has taken into account the many problems existing in the existing integrated screw chiller used to cool the cooling fan inside the chiller body 2. In order to solve these problems and save costs at the same time, the condensing fan 22 on the condensing side is directly used to cool the inside of the chiller body 2. The condensing fan 22 is also used to cool the cooling water, which reduces costs and makes full use of the condensing fan 22.

[0034] It is understandable that the present embodiment is provided with a preset temperature, and the controller compares the received temperature with the preset temperature, and controls the driving member 32 according to the magnitude relationship between the two. Specifically, when the temperature is greater than the preset temperature, the controller controls the driving member 32 to drive the ventilation louver 31 to open; when the temperature is not greater than the preset temperature, the controller controls the driving member 32 to drive the ventilation louver 31 to close.

[0035] In this embodiment, the preset temperature is set to 40° C. Of course, a suitable preset temperature can be set according to actual use needs, and is not limited to the 40° C. used in this embodiment.

Further, the chiller body 2 includes a housing 21 and components (e.g., a condensing fan 22) disposed in the housing 21, and the second through hole is disposed on the housing 21.

[0037] See also Figure 2 In some embodiments, the temperature detection element 4 is a temperature probe. It is understandable that the temperature detection element 4 can also be a temperature sensor that can detect the temperature inside the housing 21 in real time and meet the actual use requirements, and no further restrictions are made here.

[0038] See also Figure 2 In some embodiments, the driving member 32 is an electric driver. It is understandable that the driving member 32 can also select other driving devices such as motors and cylinders according to actual use needs, and no excessive restrictions are made here, as long as it can meet the use requirements.

[0039] In some embodiments, the controller is a PLC controller. In this embodiment, the PLC controller can be a host PLC of the integrated screw chiller. Of course, a separate controller can also be set up according to actual use needs to control and realize corresponding functions.

The ventilation louvers 31 of each group of heat dissipation components 3 are provided corresponding to one of the communication channels, and the driving members 32 of each group of heat dissipation components 3 are connected to the controller for communication. The controller can control one or more driving members 32 to drive the corresponding ventilation louvers 31 to open or close according to actual needs, so as to connect or disconnect the corresponding communication channels.

[0041] In some embodiments, multiple temperature detection components 4 are spaced apart along the extension direction of the chiller body 2, and all temperature detection components 4 are communicatively connected to the controller. The controller controls the driving component 32 to drive the ventilation louvers 31 to open or close according to the average temperature of multiple temperatures detected by all temperature detection components 4.

[0042] It is understandable that if a temperature detection component 4 is set alone and cannot be used normally due to failure or damage, it will affect the operation of the integrated screw chiller. In this embodiment, multiple temperature detection components 4 are set, and the temperature is controlled according to the average temperature detected by multiple temperature detection components 4, which can improve the accuracy, and when some of the temperature detection components 4 have problems, it will not affect the normal operation of the integrated screw chiller. Of course, for the temperature detection component 4 that detects a temperature that is too high or too low, the information of the corresponding temperature detection component 4 can also be transmitted to the staff through the controller so that the staff can perform maintenance in time.
