9. Calculate the amount of all refrigerant filling in this system.---(7)

Table 1) Capacity and amount of refrigerant of the indoor unit (Show-

case and Blower coil)

Note

1. Case of showcase, the condition of capacity (evaporating tempera-

ture)
Refrigeration :-10°C
Frozen

:-35°C

2. Case of blower coil, the condition of capacity is 10°C (Td).

Table 2) The amount of refrigerant of the indoor unit for air-conditioning

*Calculate for each unit.

**The total amount of refrigerant for air conditioning can’t exceed 

4.1 kg.

***In case a mix of VRV indoor and air curtains is installed the capacity 

indoor ratio of the air curtains is 45% or less of the total connected 
capacity indoor.
