Window AC and Refrigeration Basics

What are the main components of a window AC?

• heater, filter, thermostat, blower, coil

• radiator, exhaust pipe, spark plug, fuel injector, muffler

• pump, hose, nozzle, tank, gauge

• compressor, condenser, evaporator, expansion valve, fan

Explain the working of the refrigeration cycle in a window AC.

• The refrigeration cycle in a window AC involves fermentation and distillation processes.

• The refrigeration cycle in a window AC involves combustion and ignition processes.

• The refrigeration cycle in a window AC involves compression, condensation, expansion, and evaporation processes to cool the indoor air.

• The refrigeration cycle in a window AC involves only condensation and evaporation processes.

Name two common refrigerant gases used in window ACs.

• R-410A and R-32

• R-407C and R-1234yf

• R-600a and R-290

• R-22 and R-134a

What are the advantages of using a window AC?

• Expensive, difficult to install, random cooling

• Cost-effective, easy to install, targeted cooling

What are the disadvantages of using a window AC?

• Limited cooling capacity, higher energy consumption, noisy operation, and blocking natural light and views

• Limited color options, lower durability, difficult installation process

How does the compressor function in a window AC?

• The compressor in a window AC compresses the refrigerant gas to increase its pressure and temperature, facilitating the cooling process.

• The compressor in a window AC is responsible for regulating the fan speed

• The compressor in a window AC releases hot air into the room

• The compressor in a window AC cools the refrigerant gas by heating it

Describe the role of the evaporator coil in a window AC.

• Emits heat into the room

• Filters dust particles from the air

• Absorbs heat from indoor air, cools it down, and releases cooled air back into the room.

• Regulates the humidity levels in the room

What is the purpose of the condenser in a window AC?

• To release heat absorbed from inside the room to the outside environment.

• To increase humidity inside the room

• To cool the compressor

• To regulate the airflow inside the room

How does the expansion valve regulate the flow of refrigerant in a window AC?

• By shutting off the refrigerant flow completely

• By heating up the refrigerant

• By creating a pressure drop and allowing the refrigerant to expand and cool down.

• By increasing the refrigerant flow rate

Discuss the environmental impact of refrigerant gases used in window ACs.

• Refrigerant gases in window ACs help reduce global warming

• Refrigerant gases used in window ACs have a significant environmental impact due to their contribution to global warming and ozone depletion.

• Refrigerant gases used in window ACs have no impact on the environment

• The environmental impact of refrigerant gases in window ACs is positive
