The capacity given by the AC manufacturers is given at an evaporating temperature of 7°C. Well,... if you divide this capacity with 2, then you become +/- the capacity for an evaporating temperature at -7°C / -10°C (what you need for a cold room) And the unit is much cheaper (even with Mitsu) and especially with Shining now. We will try it the first time when this is possible.
