Refrigeration equipment is a device that combines a refrigerator and a facility that uses cold capacity. The design and construction of refrigeration equipment is to effectively use cold energy to refrigerate food or other items; to conduct product performance tests and scientific research tests at low temperatures; to achieve certain cooling processes in industrial production, or to perform air conditioning. Items must release a certain amount of heat when they are cooled or frozen, and the enclosure structure of the refrigeration device will also transmit a certain amount of heat when in use. Therefore, in order to maintain the low temperature conditions in the refrigeration device, it is necessary to install a refrigerator.

The upstream industries of refrigeration equipment mainly include steel industry (stainless steel and carbon steel), non-ferrous metal industry (copper, aluminum, zinc, alloy, etc.), electrical component industry (motor, water pump, fan, control system, etc.). The upstream industries of the refrigeration equipment industry are relatively mature industries in my country, so there is no situation in which raw materials or parts are in short supply or cannot be purchased. The price trend of products in the upstream industry has a certain impact on the production cost of the refrigeration equipment industry.

In 2019, the market size of my country's refrigeration equipment industry was approximately 416.8 billion yuan, an increase of approximately 7.9% year-on-year. In 2018, the market size of my country's refrigeration equipment industry was approximately 386.4 billion yuan.

In 2019, the global refrigeration equipment industry production scale reached a record 348.2 billion U.S. dollars, mainly due to the expansion of production capacity in countries such as China, India and Vietnam. As multinational companies set up factories overseas, the technology of refrigeration equipment has gradually spread to the world, and more and more countries have mastered the relevant technology and began to produce low-end refrigeration equipment products.
