Re: Solar Air Conditioners???
Dear John B.
Do you have an attic and typical pitched roof? In 1984, in Wash. State I created a passive heating system in Burlington, located 60 miles south of the Canadian border. My system has produced 90 % of all heating for a building 95' X 55' and 3 stories tall. The original "solar" heating unit cost nothing. The attic space is the solar unit. I used a remote sensor located a distance of 30" from the peak inside a 4 in 12 pitched comp black roof. I had installed a "Hot-Water" furnace on the first floor with a used hot-water radiator inside the typical squirrel cage fan system. I installed an 8" duct pipe into the top of the return air duct to squirrel cage vertical duct pipe. This pipe simply followed the roof pitch to inside next to the sensor unit. The first time this "complicated" system produced 65 degree heat occurred on Dec 23, 1984. My building temperate was 66 deg. from the gas boilers system. I was sweeping the first floor and the boiler system was turned off. I heard the fan system start and entered the boiler room to turn the remote sensor above 65 to see if the fan would stop. It stopped at 67 degree's and came back on at 65 deg. Guess what was happening outside? I went outside at 2 PM and it was snowing and 28 degrees. Three inches of snow had accumulated on the roof surface. This system has operated for 24 years and the average natural gas bill has been $6 per month. Does this help you? I built 4 more projects from Bellingham to Vancouver WA. In Vancouver, WA. I added "Passive" air-conditioning to the solar heating system. The system was built to operate with no input from any person. This system has operated since 1988 with no repairs or changes. The building is 74 x 144 x 2 stories. The inside temperature is "automatically" kept at 68 degree. The system I designed automatically changes at night to cool the building to the desired temperature and if heat is need it is automatically adjusted to +/- five degree from 68 static Temperature. The average natural gas cost for the complete building was $500 a year or $1.37 per day. Does this help you with your problem? This system requires an attic to create the cool/hot air system to work. An added bonus with this final design was the "automatic" air conditioning aspect when needed with no adjustment to the thermostat set at 65 degree. The air conditioning system was totally "automatic" with no input by manager.
I will be glad to send you the concept, costs associated with my projects in Mount Vernon and Vancouver WA. I will send pictures and design drawings if you "Actually" want to create a system. My first system in 1984, in Burlington cost less then $100 to heat a building 95' long and 55' wide and 3-stories in height. The actual cost to heat for the 24 years average's $1.00 per day. The cost of the project I created, designed and built in Vancouver WA. In 1989 was the first and only project where I created an automatic "heating/Cooling" passive solar system. This building was 142' long x 74' wide and two-stories tall. In this project I created a "Super Solar Heating and automatic solar cooling" system that required no input from the management. It has been in operation for 19 years with no adjustment or changes.

The passive Heat and cooling would average of $1.13 a day to heat and cool a building of 213,120 cubic feet. for $0.000005302 per day. I declare that this an impossible fact, "BUT it is real".
So heating your home or business using the system I have created was VALID twenty-five years age and even more so today???
I can draft the system and how it works if you so desire. I built six Mini's starting in 1978 in Centralia, WA. IF what is shown above makes sense, please respond. IF not, simply ignore.
Does this explain the process? I have not paid any money to air-condition our project to 68 deg since 1989.
ALL three of my northern project's fall into your climate zone.
Thank You, Anachronism--"Out of its Time and Place"
