REFRIGERATION AND AIR CONDITIONING Online Practice Exams FAQs
1. What is Refrigeration and Air Conditioning?
2. What are the Components of a Refrigeration System?
- Compressor: Responsible for compressing refrigerant gas.
- Condenser: Releases heat and cools the refrigerant, causing it to condense into a liquid.
- Evaporator: Absorbs heat from the surroundings and evaporates the liquid refrigerant into a gas.
- Expansion Valve: Controls the flow of refrigerant into the evaporator.
- Refrigerant: A fluid that absorbs and releases heat during the refrigeration cycle.
3. What are the Types of Refrigerants Used?
- Chlorofluorocarbons (CFCs): Used in older systems but phased out due to environmental concerns.
- Hydrochlorofluorocarbons (HCFCs): Less harmful than CFCs but still contribute to ozone depletion.
- Hydrofluorocarbons (HFCs): Used as alternatives to CFCs and HCFCs, but they have high global warming potential.
- Natural Refrigerants: Environmentally friendly options like ammonia, carbon dioxide, and hydrocarbons.
4. How Does Air Conditioning Work?
- Evaporator: Absorbs heat and humidity from the indoor air, cooling it down.
- Condenser: Releases the absorbed heat to the outdoors.
- Compressor: Increases the pressure and temperature of the refrigerant, facilitating heat exchange.
- Expansion Valve: Reduces the pressure of the refrigerant, causing it to evaporate and absorb heat.
5. What Factors Affect the Efficiency of Refrigeration and Air Conditioning Systems?
- Refrigerant Choice: Opting for environmentally friendly refrigerants with low global warming potential.
- System Design: Proper sizing and layout of components for optimal performance.
- Maintenance: Regular maintenance to keep components clean and operating efficiently.
- Insulation: Adequate insulation to prevent heat exchange with the surroundings.
- Thermostat Settings: Proper temperature and humidity settings for energy efficiency.
