Refrigerated air conditioning systems
Knowing and understanding the differences between refrigerated air conditioning and evaporative air conditioning is a good place to start in the decision making process.
A refrigerated air conditioner removes hot air, sends it outside and returns air that has been cooled, using refrigerants throughout the premises by means of various ducts or wall mounted units. Reverse-cycle models also provide heating.
Advantages of refrigerated systems:
- Works well in humid conditions.
- For every unit of electricity they use, they can provide from 1.5 to over 3 units of cooling, making them very efficient.
- Better for allergies than evaporative units.
- If it is a reverse cycle unit, it can also work as a heater.
- Some refrigerated air conditioners run on a variable speed motor (an inverter). These inverter models are more efficient than standard (single speed) refrigerated air conditioners.
Disadvantages of refrigerated systems:
- Refrigerated air conditioning requires the use of refrigerants that produce emissions, making it somewhat less eco-friendly than evaporative air conditioning.
- Because the mechanical process in refrigerated air conditioning is more complex, it also uses more energy.
- As a whole, refrigerated air conditioning is more expensive in terms of installation, maintenance and electricity costs.
- Refrigerated air conditioners use a closed system, so all windows and doors must be shut when in use.
