Technical Field

[0001] The utility model relates to the technical field of refrigeration of refrigerated trucks, in particular to a high-efficiency refrigeration unit for refrigerated semi-trailers. Background Art

[0002] Refrigerated semi-trailers, also known as insulated trucks, refer to closed van transport vehicles used to maintain the temperature of frozen or fresh goods. They transport goods that need to be kept at a relatively low temperature but do not need to be frozen, such as fresh fruits, vegetables, dairy products, etc. The temperature range of refrigerated trucks is generally between 0℃ and 10℃. They usually use low-temperature refrigeration units that can work effectively at higher temperatures.

[0003] In the use of the existing high-efficiency refrigeration units for refrigerated semi-trailers, filters or screens are often used to filter the air entering the refrigeration unit to reduce the entry of dust, thereby preventing the dust from affecting the use of the evaporator. However, the filters and screens are inconvenient to clean, which will limit the air flow, resulting in the evaporator being unable to fully blow cool air into the refrigerated compartment, thereby reducing the refrigeration efficiency. Therefore, those skilled in the art provide a high-efficiency refrigeration unit for refrigerated semi-trailers to solve the problems raised in the above-mentioned background technology.
