Abstract
Description
Technical Field
[0001] This utility model belongs to the field of refrigeration equipment technology, specifically relating to a refrigeration unit with a condenser and liquid subcooling. Background Technology
[0002] A refrigeration machine is a machine that transfers heat from a cooled object at a lower temperature to the surrounding environment, thereby obtaining cooling capacity. The heat transferred from the lower-temperature object is conventionally called cooling capacity. The working fluid in a refrigeration machine that participates in thermodynamic processes (energy conversion and heat transfer) is called a refrigerant.
[0003] The current market for evaporative air coolers and units suffers from issues such as unsaturated liquids in the evaporative air cooler's liquid distribution pipes containing flashing gas. Unsaturated liquids reduce the heat exchange efficiency of the evaporative air cooler. Additionally, the equipment is installed on a frame, typically by welding the bottom frame first and then bolting the equipment onto it. Due to the numerous pipes in refrigeration equipment, bolting in some locations is quite inconvenient during installation. Utility Model Content
[0004] The present invention aims to solve the technical problems existing in the prior art and provide a refrigeration unit with a condenser and liquid subcooling.
[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a refrigeration unit with a condenser and liquid subcooling, including a chassis, characterized in that: a plurality of equipment beams are arranged in the middle of the chassis, an equipment frame is arranged on the chassis, a condenser and a subcooled condenser are respectively inserted into the equipment frame, and a condenser inlet and outlet pipe is arranged through the equipment frame on one side of the condenser, and a subcooled condenser inlet and outlet pipe is arranged through the equipment frame on one side of the subcooled condenser. A compressor is arranged on the equipment beams, a gas-liquid separator is connected to one side of the compressor through a pipe, an oil separator is arranged on the other side of the compressor, a pressure control panel is arranged on one side of the front of the compressor, and a display instrument is arranged in the pressure control panel.
[0006] Preferably, the chassis includes a fixed frame and multiple support legs at the four corners of the bottom. Multiple slots are opened on the left and right sides of the fixed frame, and the two ends of the equipment beam are installed in the corresponding slots.
[0007] Preferably, the equipment beam is connected to plug rods on the left and right sides respectively. The plug rods are inserted into the slots on both sides of the fixed frame. The surface of the plug rod is fitted with a limiting sleeve. The top of the limiting sleeve extends upward through the slot to the top of the fixed frame. A positioning bolt is inserted between the limiting sleeve and the fixed frame.
[0008] Preferably, a locking nut is fitted onto the outer side of the corresponding limiting sleeve of the plug rod, and a rubber pad is provided inside the fixing frame corresponding to the bottom of the plug rod.
[0009] The beneficial effects of this utility model are as follows: by simultaneously rotating the subcooled condenser within the condenser's equipment frame, it cools the high-temperature liquid refrigerant coming out of the condenser by targeting the low-temperature return gas (low-pressure gas) from the evaporator inside the condenser, so that the inlet of the air cooler reaches a liquid saturation state, enabling the air cooler matched with the system to achieve optimal operating conditions and material utilization, improving product energy efficiency, reducing system operating costs and energy consumption, and improving product compatibility.
[0010] Meanwhile, multiple slots are opened on the left and right sides of the fixed frame. The equipment crossbeam is installed in the slots through the plug-in rods on both sides. This allows some equipment to be installed on the equipment crossbeam first, fixed with bolts, and then hoisted onto the chassis for installation in the corresponding slots on both sides. This makes the overall installation process more convenient and allows for pre-installation in places where bolts are difficult to fix. At the same time, the plug-in rods on both sides are fixed to the fixed frame with limit sleeves and positioning bolts. Rubber pads are installed at the bottom of the plug-in rods to reduce the vibration of the overall equipment to the chassis and increase the quietness of the entire equipment.

[0015] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0016] Example: A refrigeration unit with a condenser and liquid subcooling, such as Figures 1-3As shown, the system includes a chassis 1, with multiple equipment beams 13 positioned in the middle of the chassis 1. An equipment frame 2 is mounted on the chassis 1, and a condenser 21 and a subcooled condenser 23 are respectively installed inside the equipment frame 2. A condenser inlet / outlet pipe 22 passes through the equipment frame 2 on one side of the condenser 21, and a subcooled condenser inlet / outlet pipe 24 passes through the equipment frame 2 on one side of the subcooled condenser 23. A compressor 3 is mounted on the equipment beams 13. A gas-liquid separator 4 is connected to one side of the compressor 3 via a pipe, and an oil separator 5 is mounted on the other side of the compressor 3. One end of the gas-liquid separator pipe is connected to the compressor 3, and the other end is connected to the subcooled condenser inlet / outlet pipe 24 of the subcooled condenser 23. One end of the oil separator 5 is connected to the compressor 3, and the other end is connected to the condenser inlet / outlet pipe 22.

The two ends of the equipment crossbeam 13 are installed in the slots 14. The left and right sides of the equipment crossbeam 13 are respectively connected to the plug rods 17. The plug rods 17 are inserted into the slots 14 on both sides of the fixed frame 11. The surface of the plug rods 17 is fitted with a limiting sleeve 15. The top of the limiting sleeve 15 extends upward through the slot 14 through the fixed frame 11 to the top of the fixed frame 11.

Then, the equipment with the crossbeam 13 is adjusted onto the chassis 1, so that the plug rods 17 at both ends of the crossbeam 13 are inserted into the slots 14 on both sides of the fixing frame 11. At the same time as they are inserted, rubber pads 18 are placed under the corresponding slots 14 of the fixing frame 11 to increase the stability of the plug rods 17, thereby achieving the initial fixation between the equipment and the chassis 1. At this time, a limiting sleeve 15 is inserted at the connection between the plug rod 17 and the slot 14. The top of the limiting sleeve 15 extends upward through the slot 14 to the top of the fixing frame. A positioning bolt 16 is inserted at the top of the connection between the two to complete the installation. At the same time, a locking nut 19 is fitted on the outermost side of the plug rod 17 to further increase the connection strength.
