Swimming-pool water's cooling mode:
The 4 way valve reverses the circulation of the refrigerant fluid; the fluid vaporizes in the
exchanger (evaporator) in getting the heat of the water, goes through in the compressor which
reheats it and through in the gilled radiator (which becomes condenser) where it comes back to
liquid state.
