Inverter Split Air Conditioner
The book “Inverter Split A.C.” is an essential subject in the ITI Refrigeration and Air Conditioning (RAC) trade. It provides detailed knowledge about modern air conditioning systems that use inverter technology for improved efficiency and performance. Inverter split air conditioners are widely used due to their energy-saving capability, precise temperature control, and reduced noise levels.
Introduction to Inverter Split AC
An inverter split air conditioner is an advanced version of a conventional split AC. Unlike non-inverter systems, where the compressor operates at a fixed speed (ON/OFF), inverter AC systems use a variable speed compressor. The compressor speed adjusts automatically according to the cooling load, resulting in efficient operation and energy savings.
Main Components
The inverter split AC system consists of the following main components:
Indoor Unit
- Evaporator Coil: Absorbs heat from indoor air
- Blower Fan: Circulates cooled air
- Air Filter: Removes dust and impurities
- PCB (Control Board): Controls system operation
Outdoor Unit
- Inverter Compressor: Variable speed compressor
- Condenser Coil: Releases heat
- Condenser Fan: Enhances heat dissipation
- Inverter Circuit (Drive): Converts AC to DC and controls compressor speed
Working Principle
The working of an inverter split AC is based on the vapor compression refrigeration cycle with inverter control:
- The evaporator absorbs heat from indoor air.
- The inverter converts AC supply to DC and then to variable frequency AC.
- The compressor speed changes according to cooling demand.
- The condenser releases heat to the outside.
- The expansion device reduces pressure before refrigerant returns to evaporator.
This continuous adjustment ensures stable temperature and efficient operation.
