Refrigeration systems use a refrigerant to absorb heat from a cold source and transfer it to a hot source. The basic components of a refrigeration system include a compressor, condenser, expansion valve, and evaporator.
Types of Refrigerants
Refrigerants are substances that undergo a phase change from liquid to gas and back again. The most common refrigerants used in refrigeration systems are hydrofluorocarbons (HFCs), hydrochlorofluorocarbons (HCFCs), and natural refrigerants such as ammonia and carbon dioxide.
Design and Optimization
The design and optimization of refrigeration systems is a complex process that involves considering factors such as the type of refrigerant, the capacity of the system, and the operating conditions.
3. Air Conditioning Systems
Principles and Components, Modern refrigeration and air conditioning 21st edition
Air conditioning systems use a refrigerant to cool and dehumidify air. The basic components of an air conditioning system include a compressor, condenser, expansion valve, and evaporator.
Types of Air Conditioning Systems
There are many different types of air conditioning systems available, including central air conditioners, window air conditioners, and portable air conditioners.
Design and Optimization
The design and optimization of air conditioning systems is a complex process that involves considering factors such as the size of the space to be cooled, the climate, and the budget.
