Termination of Condensate Drains

Correct Termination of Condensate Drains

When moisture laden air (otherwise known as humid air) is drawn over the coil of an air conditioner, the water in the air freezes on the coil as it passes through.

This frozen water (condensate) melts off the coil and that water needs to be drained from the air conditioner by a licensed technician. If condensate is not plumbed in the correct way, it can cause multiple water damage conditions. Flooding the room is just one example.

The amount of condensate that a split system air conditioner generates depends on the relative humidity on the day, but rest assured, this amount is more than what most people think!

Please see the table below, which specifies the maximum amount of condensate water that each capacity of split system air conditioner will generate.

All this water has to go somewhere... and if your air conditioner is generating up to 4.7 litres an hour, it MUST drain somewhere where it:

1. Won't affect the health and safety of people around it. 
2. Won't affect the integrity of the buildings around it. 
3. Conforms with Building Authority Regulations.
4. Confirms with Body Corporate codes.

Please note that in cooling mode, the condensate is created by the indoor unit - and in heating mode, condensate is generated by the outdoor unit... A Split System air conditioner always creates water - both in heating and cooling modes!

Do you live in a high rise apartment?

If you live in a high rise apartment and don't have a drainage point for your split system, the water cannot drip (for example) 17 floors down to the ground. It must be terminated to an approved point. EZYAIR can solve your problem by installing an 'Evaporation Pan' during the installation process.

The basic concept is that the condensate water drains into the pan, an element heats the condensate water - and the heat from the element allows the the condensate to evaporate out of the pan and into the air.

There are three choices when selecting an evaporation pan:

1. EVAP1: Max evaporation 2.4 litres per hour. Sensing probe turns on & off when required. (2.4kW consumption per hour).
   
   
2. EVAP2: Max evaporation 0.18 litres per hour. No sensing probe, on all the time. (700W consumption per hour)
