anybody who has the means paying for a solar system generating net 155 kWh/day is used to yields of 7-9% per annum. we are talking of an initial investment of USD 450,000 (perhaps a few bucks cheaper in Thailand because of low labour cost).  

You must have made a typo, for USD 450,000 you can build a power plant.

no Sir, no typo. my average daily usage is 155 kWh/day and to provide for that demand the total cost of panels, battery banks and inverters is around $450k.

In German you call that “Linsensuppe”.

i beg to differ Sir. what you have presented is a delicious "Linseneintopf"

I am trying to avoid using some of my valuable solar to move air.

what about a punkah walla?

I could locate them vertically with all round ventilation and no direct sun but it would need some extension of the panel wiring (and associated losses).

why not forced cooling with something attached like this?

It's actually better to make ice (latent heat of fusion and all that high-school physics stuff you forgot straight after the exam).

 

Make 1 ton of ice and you can have 12,000 BTU of aircon for 1 day.

 

depending on the ice temperature the btu harvest can be exponentially higher. but so will be the energy cost to cool down an ice block to absolute zero -273ºC.

You can refrigerate water during the day and use it to chill your ac unit at night

interesting! does one pour the water into the inside or outside unit?

My dream is to eventually instal solar on the house roof and get the family electricity bill down to zero, also meaning zero cost to run 3 to 4 aircons for about 60 - 70% of the year.

may you live long enough to see your dream becomes reality. but don't hold your breath.

Depending on your priority, humidity or dry bulb temperature, you have a lot of options to reduce your power bill. Chilled water still seems to be hard to pull off here though.  The equivalent of a single 100-ton CalMac ice storage tank would be perfect here...

i respectfully but totally disagree. ẟt between 18ºC well water and an average of 30ºC ambient temperature is a feast for every condensing unit enough to increase efficiency exponentially. no need to play around with an expensive ice producing and storage facility plus the running energy cost for producing ice when sufficient well water is available for pennies via a simple pipe or perhaps an additional well. we are getting ~6m³ with a 1HP pump but are limited to 2HP as tests showed that 2½HP would suck air in the dry season.

moreover, our home is not an office building or factory with peak and off peak demands required for energy savings but has a rather constant demand. by the way i like RH in my bedroom <50% and in the living areas 65%.

summary: ice in my fruit juice yes, ice for condensing purpose absolutely no.

we are simple poor retired people and can't afford luxuries

Naam, please start to learn technical Thai and you'll find out that it's easier than one might think.

yeah right! because for an old fart of 76 years, with a semi deaf left ear and both ears limited to frequencies below 7kHz who needs subtitles watching movies for even those produced in his mother tongue it's a breeze to learn a tonal language.

when our cook wants to discuss something with me she calls her husband (our gardener) to translate because i hardly understand a single word (big problem hearing consonants) of her high pitched voice.

and for my wife a few meters away me asking "would you like to have kartoffelsalat with your pork chop?" my answer might be, based on her last two words, "i never refuse a blöw jöb my beloved!"

Would love to mate a 3 or 5-ton condenser to a 10m3 water tank to build a thermal storage system, but doing it with ice and refrigerant gets tricky, and adding glycol on the primary cooling loop too complicated. 

i had plans to use 18ºC well water (4-6 m³/h) for a whole-house chiller serving either 19 individual or three ducted units for zonal purpose (evaporators all refrigerant, condensers 50/50 separated by heatexchanger)  but couldn't find a qualified contractor. when i found a top company it was too late.

estimated savings would have been at least 50% electricity cost ~THB 100k/p.a.

sooner or later most of my hard working 13 years old units need to be replaced. but being an old fart who cherishes his comfortable lazy life style prevents me to make big changes.

Frankly most American wouldn't know about capillary injection or expansion valve. I assume they have to do with an AC unit but not sure.  I use our local AC guy who is great.

that depends on the store. aircon parts of course only in a specialised store. but 99% of your technical needs big stores like Lowe's or Home Depot are perfect. i designed and built a high-tech home which requires continous preventive and actual maintenance which is with very few exceptions done by ourselves.

Pound strengthened today on the news that Brexit has pretty much been cancelled.

Quote

"The British Parliament has been officially prorogued after Queen Elizabeth II approved Prime Minister Boris Johnson's request to suspend the legislative body until October 14. The prorogation order said: "Order proroguing Parliament no earlier than Monday 9th September and no later than Thursday 12th September 2019 to Monday 14th October 2019, and directing the Lord High Chancellor of Great Britain to prepare a Commission accordingly."

a beautiful area indeed. but that's where the proverbial village Nakhon Nowhere is located. one thousand miles to the next Foodland, Makro, Tesco or Friendship, 48 hours waiting time for an emergency team when you have a heart attack.

With a new UK government that seems committed to leaving the EU by October 31, we now believe that a no-deal Brexit is the most likely outcome. In this scenario, we expect the BoE to cut the bank rate 50bp by H1 20 and the currency to depreciate 9% on a NEER basis. Assuming this, we think a no-deal is fully priced into the inflation markets, well priced in equity, about 50% in credit, unevenly priced across rates, and moderately priced in equity derivatives.

FX Strategy: We forecast sterling falling to historic lows on a real trade-weighted basis, with GBPUSD as low as 1.09 and EURGBP rising to 0.99. Once the dust settles, however, we expect long-term bargain hunting and the reduction in uncertainty to lead to a partial rebound in GBP vs. the EUR.
