"New retail" has become an inevitable trend
Traditional e-commerce has used "de-intermediation" to reduce costs and replaced the functions of traditional retail for a period of time, but it is an indisputable fact that the experience of online shopping is always inferior to offline shopping. Especially for engineering industries such as refrigeration, compared with the intuitive attributes such as visibility, audibility, tactility, sensibility, usability and convenience of services that offline physical stores possess when providing customers with goods or services, online E-commerce has always been "flawed". It cannot meet people's growing demand for high-quality, heterogeneous, and experiential consumer services.

​The company was formerly known as the Refrigeration and Air Conditioning Research Institute of Qingdao University. It currently has more than 100 employees and focuses on the R&D and production of refrigeration equipment. It is mainly divided into two factories: Qingdao Cross-strait Industrial Park and Qingdao Hi-Tech Park.

Precautions for air cooler selection:
A: Air cooler frosting: When the working temperature of the air cooler is lower than zero or lower than the air dew point, frost begins to form, and the frost thickness reaches a certain level, which will cause the heat transfer of the air cooler to decrease. The coefficient decreases, the thermal resistance increases, and the wind resistance increases, which affects the heat exchange of the air cooler, so defrosting should be carried out.

What are the precautions before the operation of refrigeration equipment?
