I'm considering a "Multi-purpose indoor unit for use in 4-pipe systems for the simultaneous production of chilled and hot water by means of two independent water circuits". The unit transfers heat from a chilled water loop to a heated water loop. If the requests of heated water and chilled water are not balanced, then heat is exchanged with ambient air.
What mandatory provisions shall such a system respect? Shall I consider Table 6.8.1C?
