Coolness

I had to give up on the chiller again. I had repiped through the heat exchanger with a single path for the return water to pick up the coolness but the chiller could not reduce the temperature in the floor piping. It could do a fine job on its own loop without pumping the floor water through the heat exchanger, but the temperature of the water in both loops went up to about 73 when cooling the floor. That temperature did nothing to cool the house during the day.

So when my cousin was visiting I opened the windows at night and let the fans blow in cool Colorado night air. But during the day that was not enough.

The electrician asked me to clear out the utility room to make it easier for them to run wires there. So I took out the storage tank for the wood boiler and disassembled the chiller and removed it too. Before my brother and sister-in-law arrived I also installed the evaporative cooler in a front door. This is exactly the spot we had it installed in previous summers but we had a window then.

No more running around opening and closing windows each morning and evening! We open the windows opposite of the cooler and leave them open. The cooler keeps the indoors about mid 70’s even on the hottest days. I do turn it to low at night. One morning we woke up and it was 65 degrees in the house. It needs to run on the high speed during the day though.
These things works so well. Too bad I have to put a hole in the house if I want to install one that we don’t remove in the winter.
