Notes:
a)
The capacity of heat exchanger is obtained at these test conditions: evaporation temperature at air outlet of
heat exchanger is 6
℃
, overheating degree of heat exchanger is 5
℃
and the air return temperature is 27
℃
DB/19
℃
WB.
b)
The heat exchanger of air handling unit is
designed for R410A, and it’s working pressure is 4.2MPa.
c)
Quantity of rows of heat exchanger: no more than 4 rows.
d)
The diameter of copper pipe of heat exchanger is no more than 12.7mm. 9.52mm is recommended.
Notes: The air handling unit can be connected as a standard indoor unit to the outdoor unit.
The limitations of connection are determined by the outdoor unit.
3.4 Selecting the AHU-KIT Unit
The corresponding AHU-KIT unit needs to be selected for your air handling unit. Select the
AHU-KIT unit according to the above limitations.
Capacity ranges of different AHU-KIT unit are as follows:
