The system design and style should change slightly with the local climate that it needs to operate in.
Trying to build a one design works everywhere type of system can be done, but it wastes a lot of money. You end up with expensive features and components that you wont need.
Building a system that will operate in +50c to – 30 c is possible, but it will be expensive.
This is why it is better to modify the system and customise it for the local climate.
For example you can fit a large air-conditioner to a system that is in a hot dry climate, but an evaporative type cooling system using evaporative celdeck pads will be a lot more cost effective to operate than an air conditioner.
Another example is that you can fit a reverse cycle air conditioning system to a fodder growing system that is located in a climate that experiences – 20c overnight temperatures. The Condenser freezes up at -4c and isn’t efficient. Therefore heating the water and irrigating with warm water is for amore efficient than heating the air.
If electricity is cheap enough then we recommend heating the water inside the system and irrigating with warm water. If electricity is expensive then you will need to heat by other heating sources such as Propane Gas heating, or Diesel heating.
