A8/B3 Maintenance assessment

What is the purpose of a split AC system?

• To heat multiple rooms simultaneously

• To provide centralized cooling for the entire house

• To reduce humidity levels in the home

• To cool specific rooms or areas without ductwork

Explain the difference between the indoor and outdoor units in a split AC system.

• The indoor unit contains the cooling components, while the outdoor unit contains the heat exchange components.

• The outdoor unit contains the cooling components, while the indoor unit contains the heat exchange components.

• The indoor unit is used for heating, while the outdoor unit is used for cooling.

• Both units contain the same components but in different arrangements.

What are the common maintenance tasks required for a split AC system?

• Painting the exterior of the AC unit

• Replacing the entire system every year

• Adding more refrigerant without checking levels

• Cleaning or replacing air filters, checking and cleaning coils, inspecting electrical connections, lubricating moving parts, checking refrigerant levels, ensuring proper drainage

Describe the refrigerant cycle in a split AC system.

• The refrigerant cycle in a split AC system involves the radiator, fan, and thermostat.

• The refrigerant cycle in a split AC system consists of the stove, dishwasher, and washing machine.

• The refrigerant cycle in a split AC system includes the microwave, toaster, and blender.

• The refrigerant cycle in a split AC system involves the compressor, condenser, expansion valve, and evaporator.

What is the role of the compressor in a split AC system?

• The compressor releases heat into the room.

• The compressor compresses the refrigerant gas.

• The compressor filters the air.

• The compressor controls the fan speed.

How does the thermostat function in a split AC system?

• The thermostat in a split AC system regulates the water temperature

• The thermostat in a split AC system measures air quality

• The thermostat in a split AC system controls the lighting system

• The thermostat in a split AC system regulates the room temperature by controlling the compressor based on the temperature difference between the room and the set temperature.

What safety precautions should be taken when performing maintenance on a split AC system?

• Use a hammer to fix the AC

• Wear sunglasses indoors

• Turn off power supply, wear protective gear, ensure proper ventilation, follow manufacturer's instructions

• Spray water on the electrical components

Explain the importance of regular cleaning of the filters in a split AC system.

• Regular cleaning of the filters in a split AC system is important to maintain optimal airflow, improve energy efficiency, extend the lifespan of the unit, and ensure better air quality by reducing dust and allergens circulating in the room.

• The filters in a split AC system do not need to be cleaned at all

• Cleaning the filters in a split AC system can actually decrease energy efficiency

• Regular cleaning of the filters in a split AC system is unnecessary and a waste of time

Discuss the energy efficiency benefits of using a split AC system.

• Using a split AC system provides energy efficiency benefits through zoning capabilities that reduce energy waste by only cooling or heating occupied spaces.

• Using a split AC system increases energy costs significantly

• Split AC systems consume more energy due to their design

• Split AC systems are less energy-efficient than window units
