Gas Ducted Heating Vs Split System

Imagine stepping into your home, greeted by the perfect temperature — whether it’s a blazing summer afternoon or a chilly winter evening. The choice between an electric split system air conditioner and a ducted gas heater holds the key to achieving this tailored comfort, ensuring your living space is an oasis of coziness year-round. As we venture into the heart of 2023, the decision between these two technologies takes on renewed significance, prompting us to explore their intricacies and unearth the ideal solution for your home.

Electric Split System Air Conditioner

Here’s how an Electric Split System Air Conditioner works–

Cooling Process

Evaporator Unit (Indoor): The indoor unit contains the evaporator coil and a fan. Warm indoor air is drawn in through the return air grille and blown over the cold evaporator coil. As the air passes over the coil, heat is absorbed by the refrigerant within the coil, causing the air to cool down.

Refrigerant: The refrigerant is a chemical compound that changes state from a gas to a liquid and back to a gas, absorbing and releasing heat in the process.

Heat Transfer

Compressor: The heated refrigerant gas is sent to the outdoor condenser unit, where the compressor pressurizes it. This action increases the temperature of the refrigerant gas.

Condenser Coil (Outdoor): The hot, pressurized refrigerant gas is released into the condenser coil located in the outdoor unit. As outdoor air is blown over the coil by a fan, the heat from the refrigerant is transferred to the outdoor air, causing the refrigerant to condense back into a liquid.

Expansion Valve

The high-pressure liquid refrigerant then passes through an expansion valve (or metering device), where it rapidly expands and changes back into a low-pressure gas. This phase change causes the refrigerant to become very cold.

Cool Air Circulation

The now-cold refrigerant gas is sent back to the indoor unit’s evaporator coil, where the cycle repeats. The fan inside the indoor unit blows warm indoor air over the cold evaporator coil. This air absorbs heat from the coil, thus cooling down and circulating as cold air into the living space.
