Mode Selection

The capacity specified for the air coolers is nominal. The customer can choose the right model according to their applying condition, the refrigerant, temperature between, temperature differences etc. The real capacity can be got by the equation below:

Q_R＝Q_N×A₁×A₂

note：Q_R —— real capacity (kW)

Q_N —— nominal capacity (kW)

A₁ —— temperature coefficient see table 1

A₂ —— refrigerant coefficient see table 2

Example:

Air cooler for capacity 20KW, room temperature -25℃，evaporating temperature -32℃, refrigerant is R22.

Model Choose Steps:

1) Get heat transfer different temperature: DT=-25-(-32)= 7℃

2) According to DT= 7℃ and room temperature is -25℃, and get the temperature effect coefficient A1, check table 1, and see A1=0.77

3) Get refrigerant coefficient, check table 2, and see A2=1.

4) Get the nominal capacity:

Q_N＝Q_R÷(A₁×A₂)＝20÷(0.77×1)= 25.97 ( KW)

5) Choose the model

For the room temperature is -25℃, choose the air cooler with 8.5 fin space, and as the 25.97kw nominal capacity, the model can be: MAC98/445LE.
