Hi, we want to design a new Air to water split heat pump, we have three questions:
1.The compressor should be located in the outside unit or inside unit? Which one is better?
2.Can we place the buffer tank in the inside unit?
3.we want to design a double jacketed hot water tank , which means that it consists of two separate tanks. The hot water is heated in the inner jacket.The inside tank is 200L,the outside tank is 300L, is it ok?
Outside. Reasoning:Quote:

Possibility to install more then one indoor unit
Yes you can, but that increase dimensions of indoor unit.Quote:

Why you dont use simple water tank with conventional spiral tube heat exchanger?Quote:

we want "tank in tank "because we think it's more efficient---the heating area is bigger than spiral tube.
Did you make calculation on surface area of cylindrical tank of 200L and say 10m of pipe of 1" diameter?Quote:

Pipe of 1" diameter and 10m lenght roled in spiral (8 windings of 0,2m radius) have active area of 1.59m^2.
