Description

Technical Field

[0001] This utility model relates to the field of refrigeration unit technology, specifically a modular refrigeration unit. Background Technology

[0002] A modular refrigeration unit is a refrigeration equipment that uses modular design and assembly of components such as compressors, evaporators, condensers, and throttling devices in a refrigeration system.

[0003] Working principle:

[0004] Module collaboration: The refrigeration cycle is achieved through the collaborative work of various modules. The compressor module compresses the refrigerant into a high-temperature, high-pressure gas, and then the condenser module dissipates the heat, cooling the refrigerant into a liquid. After being depressurized by the throttling device module, the refrigerant enters the evaporator module to absorb heat and evaporate, thereby achieving the refrigeration effect. The condensate is recovered by the recovery module for cleaning and heat dissipation, improving refrigeration efficiency.

[0005] Ultrasonic atomization: It uses piezoelectric ceramic sheets to generate high-frequency vibrations, typically 1-3 MHz, which causes micron-level ripples on the liquid surface, breaking the liquid into tiny droplets.

[0006] Sound-absorbing materials reduce noise: Sound-absorbing cotton uses specially arranged pores inside to cause sound to rub against the pore walls of the material, converting sound energy into heat energy and achieving the effect of noise reduction. The sound-absorbing panel usually has a porous structure, containing a large number of interconnected tiny pores. After the sound waves enter the pores, the air molecules rub against the pore walls repeatedly, converting sound energy into heat energy.

[0007] Existing modular refrigeration units have the following drawbacks: In commonly used refrigeration units, condensate is usually discharged directly, making it impossible to use the condensate for cleaning or auxiliary heat dissipation of the refrigeration unit, resulting in a waste of resources.

[0042] Working principle:

[0043] During use, the condensate produced by the evaporator 11 flows from the drain trough 14 through the first pipe 43 into the water storage chamber 41. The condensate accumulates in the water storage chamber 41. When the first infrared photoelectric level sensor 419 detects that the water level is too high, it controls the second solenoid valve 47 to open via the PLC circuit, causing the water level to drop to the upper limit. When the second infrared photoelectric level sensor 420 detects that the water level is too low, it opens the first solenoid valve 45 via the PLC controller 7, causing the water level to rise to the lower limit. The PLC controller 7 then opens the first solenoid valve 45 and the first water pump 414, allowing the stored condensate in the water storage chamber 41 to flow freely. The water is transported to the spray pipe 53 for cleaning. The second water pump 416 is turned on to add cleaning fluid for cleaning. When the refrigeration unit is working, the atomizer 412 and the second motor 418 are driven simultaneously by the PLC controller 7. The water vapor in the atomization chamber 42 is guided to the fins 25 through the heat dissipation pipe 54. It evaporates and absorbs heat rapidly in the high temperature environment of the fins 25, thereby reducing the temperature of the fins 25 and improving the heat exchange efficiency. In addition, the recovery component solves the problem that the refrigeration unit has low cooling efficiency due to insufficient utilization of condensate, dust clogging the radiator, and low heat exchange efficiency of the radiator.

[0044] When the compressor 31 is working, it will generate a lot of noise. Sound-absorbing panels 33 are attached to the inner wall of the compression chamber 3 to absorb the noise. A rubber base 32 is provided for the compressor 31 to reduce vibration transmission. The compressor 31 is covered with sound-absorbing cotton 34 for noise reduction. The heat-conducting pipe 35 wrapped around the outside of the sound-absorbing cotton 34 is inserted into the fins 25 at the right end to prevent the temperature of the compression chamber 3 from getting too high. The compressor 31 is noise-reduced through the noise reduction components.
