Mainly I am looking at starting a AC business for houses to start with. Main issue is the Electricity bill for the compressors
People need comfort but not spend that much. I would like to develop a product
Many live with just Fans on the ceiling because of cost constraints. I am looking for a best intermediate substitute between a Fan and a compressor/refrigerant system
As I frequently point out to clients, the cheapest cooling system is a block of ice and a fan.
What is the best choice for a particular building is frequently not the least expensive
I'm assuming you mean cooler conditions, but really there isn't much other than evaporative systems which really struggle when the humidity levels increase.
Other things like ground heat pumps / sinks are expensive to build, but can be very efficient.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
If starting a AC business, the first thing to do is to research what is available from the vast number of manufacturers around the world and what's available in your part of the world, followed by gaining some insight into that / how / when / why you apply what's available.
It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)
