Description

TECHNICAL FIELD The present invention relates to a refrigeration apparatus, and to a production method of the refrigeration apparatus. BACKGROUND In a refrigeration apparatus, a compressor works on a refrigerant to realize circulation flow of the refrigerant for refrigeration, and noise is generated during working of the compressor; the compressor is provided in a compressor bin, other components, such as a fan, or the like, are generally arranged in the compressor bin and also generate noise, and these apparatuses generate heat while generating the noise, and are required to be cooled to guarantee normal working thereof. Therefore, a channel of the compressor bin communicated with the outside is necessary, and the noise generated by the compressor is also transmitted to the outside through the channel; a space inside the refrigeration apparatus is limited, and the internal limited space is occupied when a damping and noise reduction apparatus is added, such that inhibition of the noise of the refrigeration apparatus and space utilization cannot be well balanced and are difficult to consider at the same time, thus affecting a noise reduction effect, and then influencing use experiences of a user. CN 109 708 388 B relates to a compressor assembly and a refrigerator with the same. The compressor assembly includes a compressor, a fan, and an air passage, wherein the air passage is arranged between the fan and the compressor, the air passage includes a side plate and an air flow passage; the plurality of partitions are arranged in the air flow passage of the air passage, the anechoic chambers are formed between the plurality of partitions, and the plurality of anechoic chambers are mutually independent, so that the airflow generated by the fan enters the air flow passage, and is denoised through the plurality of anechoic chambers to obtain the refrigerator with lower operating noise and lower energy consumption.
