蒸气压缩式制冷双语素材
There are four basic parts in a mechanical refrigeration system.
The compressor pumps refrigerant vapor.
The condenser releases heat from the refrigerant to air or water.
The refrigerant control releases liquid refrigerant when it is needed.
Finally, the evaporator is the area that absorbs heat.
Heat is not destroyed in a refrigerator. It is simply removed from the refrigerated space and released outside.
制冷领域特点双语素材
There are few places of modern living untouched by refrigeration and air conditioning.
Business operations, manufacturing processes, storage, and shipping are almost always carried out today under controlled temperature condition.
Skilled specialists are required to design, install, and maintain controlled environments in enclosed areas that range from homes to space satellites.
Designing, manufacturing, selling, installing, and maintaining these equipment provides for many , many jobs.
Opportunities for employment in writing specifications for refrigeration and air conditioning equipment and selling this equipment have naturally grown with the industry.
Since refrigeration is used in so many enterprises, it follows that anyone who has to work in these industries must be familiar with the basic air conditioning and refrigeration processes.
All the careers in this field are available to anyone interested, regardless of sex.
