Aowei refrigeration equipment Co., Ltd is located in the coastal city of Yantai, which is one of the earliest private enterprises

established in the middle of 1980 s .The first generation founders with courage and wisdom have built the company which is mainly

engaged in refrigeration engineering and installation accessories . After several decades of development, the company has grown up

to refrigeration equipment industry chain leader under the belief of self-improvement and social service . After taking over by the

second generation owners , they devoted himself to building a high-tech enterprise center with international competition inspirit. Now

the company not only have four professional refrigeration equipment manufacturing plant engineering company and trading company,

but also building a technology Research Institute where include researching and developing compressors and compressor systems

integration , cold chain integration mainly in frozen equipment.

Aowei will continue insisting the principle of \"brand strategy, well-designed \" to produce high -tech and customer satisfactory

products. Aowei is willing to join hands with all friends at home and abroad and create a bright future.

Review the past and look forward to the future, greet the new age of development. Aowei company devote himself to manufacturing

matching with national standards and industry standard products as the company lifeline , and always putting the customer's benefit as

themselves. R D and produce the products in conformity with the international standards.

Aowei obey the national development strategy to manufacture products with advantages of \"green, low-carbon, environmental

protection ,sustainable development\" .All products and systems are intelligent, digital and realized unmanned system . Developed a

new generation series of screw refrigeration compressor successfully, the structure and the type of line parameters have a big

breakthrough. Especially for CO compressor and system , more nearly to realize \"environmental protection, safe, and efficient\". The 2

company is committed to one-stop overall cold chain solutions and value-added services . Represented by the integrated carton quick

freezer and spiral freezer machine already get more than 110 patents . The compressor test platform with experimental device and air

cooler test platform laid a good foundation for the company to the higher level.

According to country laws and regulations , all the products of our company have already got the corresponding certificates and

licence.

Introduction

安全

NH3只⽤于⾼温级部分，充注量很少。

CO2⽤于低温级部分，化学性质稳定，具有安全、⽆毒，不可燃的特性，对⼈员⽆伤害，对⻝品⽆污染。

NH3和CO2为⾃然界天然存在的物质，具有⾮常优良的环保性能。

NH3的消耗臭氧潜能值:ODP=0，全球变暖潜能值:GWP=0。

环保

CO2的消耗臭氧潜能值:ODP=0，全球变暖潜能值:GWP=1。

节能

CO2的蒸发潜热较⼤，单位容积制冷量相当⾼，⼜具有优良的流动性和传热特性，可显著减少压缩机、

换热器规格及管路尺⼨，使整个系统⾮常紧凑。

NH3是效率较⾼的常规制冷剂。

Safety

CO2 is used in the low-temperature part, with stable chemical properties, safe, non-toxic and

non-flammable, no harm to personnel and no pollution to food.

NH3 is the most efficient standard refrigerant

The ozone depletion potential value of NH3 is ODP = 0, and the GWP global warming potential

value = 0.

The ozone depletion potential value of CO2 is ODP = 0, and the GWP global warming potential

value = 1.

NH3 is only used in the high-temperature part, and the charging amount is very small.

Environment Protection

NH3 and CO2 are natural substances , have excellent environmental performance.

Energy Saving

The latent heat of evaporation of CO2 is large, the cooling capacity per unit volume is quite

high, and it has excellent fluidity and heat transfer characteristics, which can significantly reduce

specifications of compressors and heat exchangers , dimensions of pipes.

Aowei refrigeration follow the 'green,low carbon,environmental protection,sustainable

development'of the national development strategy,after years of efforts to spend huge sums of

money to build NH3/CO2 cascade refrigerating system and secondary refrigerant refrigerating

system laboratory,which the core technology and Related equipment for experimental

demonstration.Design and test of NH3/CO2 plate and shell type condensing evaporator,designand

test of NH3/CO2 cascade refrigerating oil return system,regulator of NH3/CO2 cascade refrigerating

system improvement and testing,design and test of CO2 air cooler blower for CO2 stainless steel

tube,design and test of CO2 direct expansion liquid supply system,test of CO2 pipeline resistance

measurement,hot gas defrost test of CO2 drainage pipe,evaporation of CO2 pump Measurement of

the amount of liquid in the chamber,the energy saving control test of CO2 hot gas defrost,the

optimized design of the plate and shell type condensing evaporator with gas-liquid separation

function,the design and test of the supercooled siphon receiver,and theautomatic control design

and test,compressor unit oil pump frequency control test,CO2 filling system improvement.Thus

forming a complete set of CO2 subcritical refrigerating system application theory system.After a

series of commercial operation,its excellent performance,reasonable design and safety,energy

saving,environmental protection received wide acclaimcustomers!

In the development of the road,Aowei refrigeration will continue to explore......
