Understanding the Basics of Air Conditioning Systems: A Guide for Aspiring Engineers

Understanding the fundamentals of air conditioning systems is important for any aspiring engineer. This guide provides an overview for those entering the field.

What is an Air Conditioning System?

An air conditioning system is designed to regulate the temperature (heating or cooling), humidity and air quality of indoor environments. It works by extracting heat from indoor air and dissipating it outdoors, thereby cooling the space and/or heating the space by reversing the function of the evaporator and condenser.  The main components of an air conditioning system include the compressor, condenser, evaporator, expansion device and refrigerant.

How Do Air Conditioning Systems Work?

1. Evaporation: The refrigerant absorbs heat from the indoor air via the evaporator coils, causing it to evaporate and transition from a liquid to a vapour.
2. Compression: The gaseous refrigerant is compressed by the compressor, increasing its pressure and temperature.
3. Condensation: The high-pressure vapour travels to the condenser coils located outside, where it releases the absorbed heat and condenses back into a liquid.
4. Expansion: The liquid refrigerant then passes through an expansion device, lowering its pressure and temperature before returning to the evaporator to repeat the cycle.

Types of Air Conditioning Systems

1. Central Air Conditioning: Ideal for large buildings, central systems use ductwork to distribute conditioned air evenly throughout the space.
2. Split Air Conditioning: Common in residential and small commercial settings, these systems consist of an indoor unit and an outdoor unit, connected by refrigerant lines.
3. Window Units: These compact, self-contained units are installed in windows or wall openings and are suitable for cooling single rooms.
4. Portable Units: Mobile units that can be moved between rooms, providing flexible cooling solutions.
5. Heat Pumps: Most modern systems are Heat Pumps. Split Systems and VRF/VRV systems are ‘air to air’ Heat Pumps.   Air Source Heat Pumps are air to water systems, extracting heat from the outside air and using it to heat water for domestic use and/or space heating

Key Components

• Compressor: The heart of the system, responsible for compressing the refrigerant and driving the cooling cycle.
• Condenser: Releases the absorbed heat from the refrigerant into the outdoor air.
• Evaporator: Absorbs heat from the indoor air, causing the refrigerant to evaporate.
• Refrigerant: A chemical compound that cycles through the system, absorbing and releasing heat.

Maintenance and Energy Efficiency

Regular maintenance is essential to ensure the efficient operation and longevity of air conditioning systems. Key maintenance tasks include:

• Filter Replacement: Regularly replacing or cleaning filters to maintain airflow and improve indoor air quality.
