However, current high-density DC inverter air conditioners have unsatisfactory cooling efficiency and cannot effectively solve the hotspot problem in data centers.

[0003] Therefore, the applicant has developed a high-density heat dissipation DC inverter air conditioning unit for computer rooms to solve the above problems. Utility Model Content

[0005] This utility model achieves the above objectives through the following technical solutions:

The drip tray is located on the bottom surface of the cabinet. The bottom end of the evaporator is connected to the drip tray. The water tank is located below the drip tray and connected to it. The drip tray is connected to the water pump, which is used to connect to a water supply source. The evaporator and the drip tray divide the interior of the cabinet into a return air zone and a supply air zone. The return air zone is connected to the outside through the air inlet, and the supply air zone is connected to the outside through the air outlet. The filter assembly, compressor, oil-gas separator, liquid receiver, and water pump are all located in the return air zone. The compressor inlet is connected to the gas collection pipe of the evaporator.

The oil-gas separator separates the oil from the high-pressure gas discharged from the compressor and returns it to the compressor through the oil return pipe, ensuring sufficient oil lubrication for the compressor's rotating components. The electronic expansion valve reduces the pressure of the high-pressure liquid at the condenser outlet and simultaneously regulates the refrigerant flow into the evaporator, ensuring that the liquid refrigerant in the evaporator matches the unit's cooling capacity. The dryer filter absorbs water molecules from the liquid refrigerant and filters out impurities. The liquid circuit solenoid valve cuts off the refrigerant flow in the piping by de-energizing and energizing the copper pipe.

[0014] Furthermore, a temperature and humidity detection board is provided in the return air zone near the evaporator, and the temperature and humidity detection board is connected to the controller.

The evaporator 3 and the drip tray 1-8 divide the interior of the cabinet 1 into a return air zone and a supply air zone. The return air zone is connected to the outside through the air inlet, and the supply air zone is connected to the outside through the air outlet.

The outlet of the liquid storage tank 7, the dryer filter 13-4-1, the liquid circuit solenoid valve 13-4-2, the electronic expansion valve 13-4-3, and the evaporator 3 are connected in sequence.

[0042] A fan assembly is disposed within the air supply zone, and the fan assembly includes a plurality of vertically arranged fans 4;

[0043] The electrical control component 12 is connected to the compressor 2. The electrical control component 12 includes an electrical box 12-1, a frequency converter 12-2, a switching power supply 12-3, and an ATS dual power supply 12-4. The electrical box 12-1 is a metal box. The frequency converter 12-2, the switching power supply 12-3, and the ATS dual power supply 12-4 are fixed in the electrical box 12-1 by fasteners. The frequency converter 12-2 is connected to the compressor 2 as the control actuator of the compressor 2. It controls the operating status of the compressor 2 by receiving instructions from the controller 9. The ATS dual power supply 12-4 and the switching power supply 12-3 determine whether the compressor 2 is powered or not by switching them on and off. The controller 9 is used to detect the operating status of the compressor 2, the fan assembly, the hydraulic solenoid valve 13-4-2, and the electronic expansion valve 13-4-3, and at the same time detect the environmental status and issue instructions to control the operation of each device.

[0044] The controller 9 is connected to the compressor 2, the fan assembly, the hydraulic solenoid valve 13-4-2, the electronic expansion valve 13-4-3, and the electrical control assembly 12.

[0045] like Figure 4 and Figure 5As shown, the piping assembly 13 includes an intake pipe 13-1, an exhaust pipe 13-2, an inlet pipe 13-3, and an outlet pipe 13-4. The inlet of the compressor 2 is connected to the gas collecting pipe of the evaporator 3 through the intake pipe 13-1. The exhaust pipe 13-2 is led out from the outlet of the compressor 2 and connected to the oil-gas separator 8. The exhaust port of the oil-gas separator 8 is used to connect to the external unit piping. The inlet of the liquid storage tank 7 is connected to the inlet pipe 13-3. The inlet pipe 13-3 is used to connect to the external unit piping.

[0046] The suction pipe 13-1 connects to the inlet of compressor 2 and the gas collection pipe of evaporator 3. The discharge pipe 13-2 leads out from the outlet of compressor 2, passes through oil-gas separator 8, and connects to the outdoor unit pipeline. Liquid refrigerant flows from the outdoor unit pipeline into the liquid inlet pipe 13-3, passes through the liquid receiver 7, and enters the liquid outlet pipe 13-4. In the liquid outlet pipe 13-4, the refrigerant passes sequentially through the dryer filter 13-4-1, the liquid circuit solenoid valve 13-4-2, and the electronic expansion valve 13-4-3, and finally enters the evaporator 3. Under pressure, the refrigerant circulates in the pipeline assembly 13, playing a role in heat transfer and cooling. Its specific working principle is that the air conditioning compressor 2 converts potential heat into a high-pressure, high-temperature state, and through the action of system components, forms a low-temperature, low-pressure cooling effect, completing the air conditioning system cycle.

[0047] The filter assembly 6 is placed on the rear door assembly 1-2, the piping assembly 13 is centrally located below the return air area, and the electrical control assembly 12 is located on the left and right sides of the return air area for easy maintenance and operation.

The precise horizontal air supply mode can achieve near-end cooling, solving the problems of high heat density and local hot spots in the data center.

[0048] The electronic control component 12 adjusts the compressor speed by changing the DC voltage, thereby changing the cooling capacity of the air conditioner. When the indoor temperature drops or rises rapidly, the indoor air conditioning load increases, the compressor 2 speeds up, and the cooling capacity increases proportionally. Conversely, when the indoor air conditioning load decreases, the compressor 2 operates normally or slows down. Compared to fixed-frequency air conditioners, DC inverter air conditioners can achieve an annual energy saving rate of up to 29%, greatly improving energy efficiency.

The front and rear door panels are evenly distributed with hexagonal holes of 8mm circumcircle and 1mm spacing, achieving a ventilation rate of 78%. The controller 9 is installed above the front door assembly 1-1, and the front door assembly 1-1 also has an air vent grille 1-1-1 installed in it. The air supply angle can be adjusted by adjusting the angle of the air vent grille 1-1-1. The screw-connected assembly frame is easy to manufacture and assemble, easy to operate and maintain, and inexpensive. At the same time, according to the front-end requirements, the frame can be expanded and upgraded by flexibly using C-profiles 1-11-1, corner pieces 1-11-2, and frame connectors 1-11-3.
