Monday morning

The work day in the shop is about to begin so we started the heat-pump. I still have to do some control work, the system is still all manual. I will still be supervising the system closely as I would not like anything crazy to happen.

As seen in the photos 9:00am and the shop is starting out at 11 Deg. C The heat pump is reduced to 35 Hertz and 6.8 amp and the coolant temp to the air handler in the shop is climbing through 36 Deg.C Using the input of 1428 watts this equates to 1.9 Ton and from what I've seen so far the temp to the air-handler will settle out to 45 Deg.C which is plenty.

A quick calculation utilizing a operational time of 10hrs /day is approx. $90.00 per month. NICE!!

In the photos you will see the current draw temps. and the frost on the copper line out of the TXV.

I have on order some HI/LOW limit switches as well as some additional relays. I'm also going to put a cold control on the suction to prevent an accidental freezing of the HX.
