Product Capacity Rectification - BGH GMV6 Technical Sales Manual

NOTES:
a. The circuit breaker and power cable specifications are selected according to the maximum unit power
(maximum current).
b. The power cable specifications are obtained under the condition that the multi-copper core cable
(such as YJV copper-core XLPE insulated PVC sheathed power cable) is laid in the wire trough in an
exposed manner (the ambient temperature of use is 40°C and the cable operating temperature is 90°C)
(IEC60364-5-523). If the use condition is different, calculate and adjust the specification according to
the corresponding national standard.
c. The copper core cable must be used.
d. The sectional area of lead applies to the maximum distance of 15 m. If the distance exceeds 5 m,
the sectional area of lead must be increased accordingly to prevent burnout of the lead or a fire due to
current overload.
e. The circuit breaker specification is obtained under the condition that the ambient temperature is
40°C when the circuit breaker is operating. If the use condition is different, calculate and adjust the
specification according to the instructions on circuit breaker specifications.
f. The circuit breaker should provide the magnetic trip and thermal trip functions at the same time to
ensure protection in the cases of short circuit and overload.

PRODUCT CAPACITY RECTIFICATION

4.1 Capacity code
IDU capacity code=IDU rated cooling capacity value (W) ×0.01
ODU capacity code=ODU rated cooling capacity value (W) ×0.01
E.g: Rated cooling capacity of GMV-224WM/G-X is 22400W, its capacity code is 22.4kW;
Rated cooling capacity of duct type IDU GMV-ND22PHS/B is 2,200W, its capacity code is 2.2kW.
4.2 Capacity rectification method for IDU and ODU
Actual capacity of each IDU=Actual capacity of ODU×IDU capacity/Max. IDU capacity operating at the
same time
Actual capacity of ODU=Rectified capacity based on the configuration rate of IDU and ODU and the
indoor and outside temperature condition×pipe distance and the rectification coefficient of fall of IDU
and ODU×rectification factor of heating and defrosting
NOTES:
a. Rectified capacity based on the configuration rate of IDU and ODU and the indoor and outside
temperature condition——inquire according to the capacity rectification table
b. Rectification factor of heating and defrosting——rectify the factor if the model selection is based on
heating load.
