you forgot to mention that with chillers you also need a vent system like an aluminum air hose into the ceiling or a window to expel the hot hair...
otherwise the unit will keep fighting itself as it heats up the room with its motor..
whether people call them mini-ac units, chillers, or full on AC's...they all do the same...run the liquid through rad system which refrigerant inside to cool it...
once the refrigerant becomes hot...it'll travel through the path of least resistance (angled pipe) pushing the cold refrigerant back down on the other side...
it's also the reason AC/fridges etc....can't run non-stop because once ALL the refrigerant goes over a certain temp it stops doing what it's supposed to...(cooling things down)
running a mini-AC can still use around 300-500 watts which is about the same as having a computer on 24/7
specially with lots of people complaining about the costs of energy these days it's just not feasible for many
and if people truly want to invest in this...
might as well buy a car battery put a solar panel on a window to charge it and run it solar...
the power you need during the day would be provided by the sun and when night time comes the battery would have a full charge to power this on
I would also like to remind people the average cost for a home computer with a simple quadcore cpu 24/7 pre-war was about 250-300$/year
so the cost of energy VS the cost of investing in solar/battery power pays for itself as fast as 1 to 2 years
now looking at google for chillers....
Mini Water Chiller - The World's Smallest Cooling System
www.rigidhvac.com
this guy lists at -16C ~ 30C can run from as low as 100w to 400w
and from what I saw on the specs the compressor has an overload shutoff protection (which will shut it off in case the temp keeps going up from running non stop)
and goes for $460 US...
but me being me..I gotta check prices so amazon I went...
and for the amazing price of 79$ I found these little guys:
https://www.amazon.ca/dp/B07F1V2B5Z/?tag=
2 of these combined with a thermostat of 18$ --->
https://www.amazon.com/dp/B07HF6MSRS/?tag=ff0d01-20
does roughly the same job for half the buying cost....
now total expenses....
we'll use UK prices as energy costs are going up everywhere and UK would be a standard in the future with this global energy cost increase...
prices right now are listed at 0.36/kWh
running 2 of these (360w) with the thermostat (3w) plus lets say a 200gph pump at 25w for 12h/day as it turns on/off according to temp...(388w)
costs currently 50.28£/month or 611£/year
running the first guy alone at 500w for the same time costs 64.8£/month ~ 788.4£/year
now...
costs for solar with sources from common places found on google....
a 450w panel goes for 315$ canadian dollars
https://solarpowerstore.ca/collecti...m-455w-solar-panels-free-shipping-canada-wide
a car battery 130$ CA with 35 Ah capacity at walmart
https://www.walmart.ca/en/ip/12V-35...with-Minn-Kota-Sevylor-Marine/PRD6UI3XX1QLO90
but we need night power from let's say 6pm to am assuming our system needs to power the units for half that time that's at least 6hours of power
in case of the 388w system it needs 2328watts of stored power or a 12v 200Ah battery...
https://offgridsupply.ca/agm-12v-200ah-deep-cycle-battery-heavy-duty/
damage for a battery like this is 620$ canadian which just increased our investment by quite a bit...
now as solar uses DC we also need a power controller for the incoming power out to the battery and then an inverter...
power controllers can be found on amazon for 30 bucks for 60amps which is more than double the capacity support we need for the 400w panel
and then the inverter at 135$
https://www.amazon.ca/dp/B08RJ3HXND/?tag=
so our solar system damage becomes 315$ for panel / 620$ for battery / 30$ for charger controller / and 135$ for inverter with a grand total of 1100$ canadian
788£/year (846$ US) to run a chiller on grid VS buying a small solar kit for 1100$ CA (809$ US)
the investment would pay for itself in 1 year
I myself can't put a solar panel on my window as it is against condo rules in my building but for the people that can
a small system like this can make an impact on your yearly energy costs
and for the people that own their own house...they should look to stronger power controllers/inverters as these are the main parts that make it future proof for adding capacity to the system
such as more panels/batteries and constant output power
These are just ideas that can save lots of money in the long run specially for people that tend to have MTS or fish rooms
