Hello guys,
Currently I'm working on prototype air/water reverse heat pump.
In the picture below is shown the main hydraulic scheme of this heat pump.
10621
Due to the variable speed compressor and not permanent working load, I thinking about installing liquid receiver. Furthermore Coil's and BPHE's volumes differs twise ( 4,5 vs 2 ltr), so for reverse system liquid receiver is mandatory. I'm right or not?
For the better efficiency I want to install subcooler in the liquid line (8). What's your oppinion about subcoolers in heat pumps?
For the heating mode the system should work properly I guess, but the problems should occur in cooling. In the cooling mode subcooler won't work.
What can you say about this scheme? What's your recomendations about components added?
Moreover, I can't find any producers of Surge liquid receivers. In the reverse refrigerant circle it fits much better than the conventional one.
