How does an Evaporative Cooling system work?

Fresh air from outside is drawn into the home through the cooler located on the roof. The cooler has a water supply that wets four pads, the air is then drawn through resulting in air being cooled through the process of evaporation. As an example if you wet your finger and then blow on it you will feel the cooling effect of evaporative cooling.

This cooling system is ideal for dryer climates.

Does an evaporative cooling system use much water?

The amount of water used is in direct relation to the outdoor humidity level. If it is a hot dry day the unit will use more water through evaporation. The water usage is minimal and you will not notice the impact of using an evaporative system during Melbourne’s summer period.

How much electricity does an evaporative cooler use?

The use of electricity is very low.  It’s needed to drive a fan and a small water pump.

Can an evaporative cooling system be zoned?

There is no zoning option on the evaporative cooler. However a simple method that is very effective is to control the air by slightly opening windows in the room you want the cool air. The evaporative system slightly pressurises the home therefore an open window immediately directs the air to that area.

What information should I have ready before I talk to my  heating and cooling specialist?

In an ideal situation a house plan with accurate room dimensions we will need to provide an accurate quotation. In some cases this is not possible and a site visit is required to draw up a floor plan and take measurements.

Will an evaporative cooler keep my house cool throughout an extreme summer period?

It will cool your house on most days however when there is high humidity the evaporative system does not work as effectively.

A refrigerated system will provide cooling throughout extreme heat as it is not impacted by humidity levels.

How does a refrigerated air conditioner work?

This is the most effective form of cooling. The process is to transfer heat. Heat is absorbed into a refrigerant gas (what?? Chamber??) and dispersed in another area. In summer the heat in your home is collected by the refrigerant in the indoor fan coil unit and dispersed outside through the condenser unit. It works on the same basic principle as your refrigerator.

In winter a reverse cycle system heats instead of cools your home.

Can I have the windows and doors open with a refrigerated cooling system?

For refrigerated cooling system this is not recommended, however if you have an evaporative cooler installed then it is a requirement to have the windows and or doors open for operation.

What size air conditioning cooling system do I need?

What is a split system?

Yes. Home insulation, window coverings, open doors and windows as well as the set point all affect the running costs considerably. For example, every 1 degree temperature difference should result in approximately a 6 percent increase in running costs.

How does gas ducted heating compare to other central heating systems?

Gas heating can be cheaper to run in Melbourne however Heat Pump technology and sensible zoning now means reverse cycle systems can be as cheap or cheaper to run.

Can I operate my ducted heating and cooler from the one controller?

Generally yes however it depends on the brand and number of units. There are systems that require two controllers.

Where is the gas heater installed?
