Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an integrated machine room air conditioner. Background Art

[0002] With the rapid development of information technologies such as big data and cloud computing, the current data center has put forward higher and higher requirements for rapid construction and convenient installation. Among them, the air conditioning system, as an essential component of the data center, can cool the data center to ensure the efficient and reliable operation of the data center. However, the traditional computer room air conditioner is divided into indoor and outdoor units. The outdoor unit must be installed outdoors, and it is necessary to design the pipe route and reserve the pipe position. The outdoor unit can only be used after being connected with the indoor unit by pipes to form a closed loop of the refrigeration system. The separate installation of the indoor and outdoor units will inevitably cause the connecting pipes to be too long, which will not only increase the cost, but also cause the loss of cooling capacity of the pipes and increase energy consumption. During installation, it is necessary to install the indoor and outdoor units on site and weld the connecting pipes. The outdoor unit is far away from the indoor unit, and there are hidden dangers of damage and leakage in the pipes. Not only is the installation efficiency low, but there is also the risk of fire.

[0003] Some office buildings were not considered to install computer room air conditioners at the beginning of construction. They were all central air conditioners for centralized cooling, which could not meet the high-precision requirements of constant temperature and humidity in the computer room. There was no place to install the outdoor unit of the air conditioner on the glass curtain wall of the office building, and the room had no drainage system, which resulted in the computer room being unable to meet the requirements of installing computer room air conditioners. Central air conditioners could only be used to cool the servers. The temperature control accuracy of central air conditioners had large deviations and could not achieve constant temperature and humidity, which affected the service life of the servers in the computer room. Even if traditional air conditioners can be installed, if there is a need to renovate the data center, the online pipelines need to be disassembled and reinstalled under the traditional air conditioner's separate installation method of the internal and external units, which is difficult to renovate.

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 8As shown, in this embodiment, an integrated machine room air conditioner is provided, including a chassis, a compressor 6, an evaporator 4, a fan 7, a condenser 3 and a control unit 22. A partition 21 is provided in the middle of the chassis, and the partition 21 divides the chassis into two cavities, one of which is provided with a condenser 3, a control unit 22 and a fan 7, and the other is provided with an evaporator 4, a compressor 6 and a fan 7. The compressor 6, the evaporator 4, the expansion valve 5 and the condenser 3 are connected end to end to form a refrigerant working medium circulation loop. The cavity where the condenser 3 is located is provided with a natural wind inlet pipe and a hot wind exhaust pipe, and the natural wind inlet pipe and the hot wind exhaust pipe are both connected to the outside. The cavity where the evaporator 4 is located is provided with an air inlet and an air outlet, and the air inlet and the air outlet are both connected to the room. The compressor 6 and the fan 7 are respectively connected to the control unit 22 for communication. In this embodiment, the integrated air conditioner structural design only needs to stretch the retractable air duct 20 of the condenser 3 to the outside and connect the power supply to use it, which reduces the installation time and the product can be put into use immediately.

[0022] As an optional solution, the two cavities in this embodiment are an upper cavity 1 and a lower cavity 2, respectively. A condenser 3, a control unit 22 and a fan 7 are arranged in the upper cavity 1, and an evaporator 4, a compressor 6 and a fan 7 are arranged in the lower cavity 2.

The motor 17 is fixed on the chassis, and the rotating shaft of the motor 17 passes through the top of the water splashing tray 13 and is connected to the impeller 14. The impeller 14 is located below the center line of the condenser 3, which is convenient for splashing water to cool down the condenser 3 over a larger area, accelerating the heat exchange of the condenser 3, and thus saving the energy required for refrigeration.

[0026] As an optional solution, in this embodiment, at least two groups of water splashing components are evenly distributed in the water splashing tray 13; the coil of the condenser 3 is semi-enclosed on the top of the impeller 14, so as to splash water to cool the condenser 3 in the maximum range.

[0027] As an optional solution, in this embodiment, the depth of the water receiving tray 9 is greater than the depth of the water splashing tray 13, so that the amount of water received is greater than the amount of water splashed, which is convenient for collecting more condensed water.

[0028] As an optional solution, in the present embodiment, a high water level switch 10 and a low water level switch 11 are provided in the water receiving tray 9. The high water level switch 10 and the low water level switch 11 are respectively communicated with the control unit 22.

The two door panels (front door panel 15 and rear door panel 16) of the chassis are respectively provided with an air inlet and an air outlet, and the air inlet and the air outlet are both hollow mesh panels.

[0031] As an optional solution, in this embodiment, a universal wheel 8 with a brake is respectively provided at the four corners of the bottom of the chassis. The design of the universal wheel 8 at the bottom allows the user to move the air conditioner close to the heat source at any time, and the air conditioner can be easily moved without disassembly during the renovation of the computer room, which truly saves costs and time, and is fast and convenient for customers to use.

[0032] The energy-saving principle of recycling and reusing condensed water in this embodiment is as follows: a water receiving pan 9 is installed at the bottom of the evaporator 4, and a water receiving pan 9 is installed at the bottom of the condenser 3. During refrigeration, the condensed water generated by the evaporator 4 is collected in the water receiving tray 9. A high water level switch 10 and a low water level switch 11 are installed in the water receiving tray 9. A water pump 12 is configured. The start and stop of the water pump 12 is controlled by the water level switch. When the water level is low, the water pump 12 stops working. When the water level is high, the water pump 12 starts working. The condensed water is pumped from the water receiving tray 9 to the water splashing tray 13 by the water pump 12. Two sets of impellers 14 are installed in the water splashing tray 13. The position of the impeller 14 is as close to the center of the bottom of the condenser 3 as possible to prevent the water from splashing out of the water tray when the impeller 14 rotates. The condensed water is splashed and atomized by the rotation of the impeller 14. The impeller 14 is driven by a motor 17. When rotating at a high speed, the condensed water can be thrown out and formed into a fine water mist, which hits the fins inside the condenser 3. The atomized condensed water evaporates on the surface of the condenser 3 and takes away a large amount of heat, thereby reducing the temperature of the condenser 3. This not only improves the refrigeration efficiency of the air conditioner, but also reduces the workload of the compressor 6 and reduces energy consumption. Experimental data show that the energy efficiency ratio of air conditioners can be significantly improved through condensed water atomization. The application of condensed water atomization technology in air conditioning systems not only solves the problem of condensed water discharge, but also effectively utilizes condensed water resources, significantly improves the energy efficiency of computer room air conditioners, and is an important innovation in the field of energy saving of computer room air conditioners.

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
