Refrigerators are based on a different approach. They only need to kick on once in a while because they are heavily insulated.The vapo chill has to run constantly because it is under a continuous, high (for it's size) heat load.
Some food for thought. It's "do the math time again":
Hidden cost of a PC is the electricity. Figure 12 cents a kilowatt hours (yours may be higher or lower).
Average of 6 hours a day in use, 7 days a week is 42 hours times 52 weeks a year is 2182 hours a year.
Power consumption is 180W for a 17 inch CRT plus 350-450W depending on your cpu, ram and vid card.
450w * 1kw/1000w * 2182 hrs * $0.12 = $117.83 per year
Now add in a vapo chill system with a COP of 0.5 removing 100 W (CPU plus line losses). Close to $150 per year.
Now lets get really depressing. Assume 3 PC's in the house (spouse, couple of kids). Thats up to $450 per year.
But it gets worse. If you live in a hot climate you have to get rid of that extra 1200 kW-Hrs in the summer so add another 150% / 2 (half the year for air conditioning) to the amount of electricity used, assuming a high efficiency air conditioner. We're up to about $600 per year in electricity costs.
The good news is my computer room is nice and warm in the winter.
I had a point in here somewhere. Oh yeah. There's one hell of a lot of waste heat, burned fossil fuels and pollution associated with running that PC. Lets not make it worse by using vapor cycle compressors to cool them. We're just encouraging the CEO of Intel to make statements like "Well, I think 100W for a CPU is acceptable. It sure is, if he doesn't have to pay for it.
