EMRQ8A Capacity correction
1. Rate of change in heating capacity
[Notes capacity correction]
1 These figures illustrate the rate of change in capacity αof a standard indoor unit system at nominal load under standard conditions.
Moreover, under partial load conditions there is only a minor deviation from the rate of change in capacity shown in the figures above.
2 With this indoor unit, constant evaporating pressure control during cooling and constant condensing pressure control during heating is carried out
3 Method of calculating capacity Connection ratio = 100%
[Capacity] = [Capacity under 100% connection ratio (Capacity table)] X [Correction factor for capacity αdue to piping length to farest indoor unit]
[Explanation of symbols]
