Solar air conditioning

[georgios]

Hello everyone,

This new technology has produced a new breed of air conditioning units
powered with solar panels or directly off the battery storage. Operational
voltage required is from 85 to 600 watts depending on the model, bypassing
the problem of having typical AC air cond connected to the inverter.

Are these units available in the DR?

Thanks in advance,
Georgios.

I haven't seen any, but I have heard about them in Sweden.

I'm 99.9% sure they are not being used here yet.

I think most of the year in Sweden if you want to cool your house you just open a window...

On the actual set up, and sequence of operation.

If you are referring to evaporative coolers then they will not work in the DR. They do work very well in dry climates.

My sister has had several in Utah and Colorado.

I believe the problem is that at yet the technology available is too expensive and would only be cost-effective for very large operations.

But if petroleum stays high, there is more incentive for new technology to be developed.

Lots of links on Google on the subject. Here is one interesting one.

Here is my findings after reviewing residential grade solar air cond units in
the market today.

ORDINARY SPLIT TYPE 110/220VAC
Capacity......................................18,0 00 BTU
Cooling area....................................900 sq ft
wattage.........................................57 00 watts
Price............................................. .$400 US


SOLAR OR WIND SPLIT TYPE 24VDC (NO EVAPORATION COOLER)
Capacity.......................................18, 000 BTU
Cooling area.................................... 275 sq ft
Power............................................ 650 watts
Price............................................. $1,550 US*

* Does not include solar panels or wind turbine.

Savings in power consumption is 60-80%. Solar panels cost
about US$5,000 (initial cost high). Panel's lifetime is 25 years.
Rectifying local AC grid power to DC is possible when on.
Running on battery storage on a timer also a good idea.
Fortunate people with good wind resources can run on
a wind turbine 24VDC output.

The units look good, click on http://www.hassino.com
I found several manufacturers offering similar products.
Payback projected at 3-4 years. Lifetime 10 years.

Comments welcomed.
Georgios.

No real technical information on the web site, but I would be willing to buy one to try it.

How are the wind turbines going?

How are the wind turbines going?

The first shipment is coming to port in about 55 days.
It contains wind turbines, towers, AGM batteries, solar
well pumps, solar pool pumps, pure sine wave inverters,
surge arrestors and a plethora of other renewable products.

I invested about 2 years trying to source the best products
available with the lowest cost possible. Most of it is not
available in the DR. All my suppliers are reputable & reliable.
My partner is a well known American/Canadian living in Cabrera
for many years. He assisted in identifying what is really needed
in the DR to overcome the power supply problems. Special attention
was given so the new products "tie in" to the existing equipment
people already purchased (inverters, batteries etc) to avoid added
replacement costs.

looking forward to post my website on DR1. I believe all the DR1
members will appreciate the effort. I thank them for taking the
time to read my comments I posted.

Saludos,
Georgios.
