IEER = (0.02 * A) + (0.617 * B) + (0.238 * C) + (0.125 * D)

Where as:

A = EER at 100% net capacity at AHRI standard condition (95 deg F)

B = EER at 75% net capacity and reduced ambient (81.5 deg F)

C = EER at 50% net capacity and reduced ambient (68 deg F)

D = EER at 25% net capacity and reduced ambient (65 deg F)

Example:

A = 11.0 EER B = 16.0 EER C = 19.0 EER D = 23.0 EER

IEER = (0.02 * 11) + (0.617 * 16) + (0.238 * 19) + (0.125 * 23)

IEER = 0.2 + 9.8 + 4.5 + 2.9 =17.4 IEER

Part load performance of commercial HVAC systems

was represented as Integrated Part Load Performance

(IPLV) which was used until january 1, 2010. Then

a new methodology was adopted and deﬁned as

Integrated Energy Efﬁciency Ratio (IEER).

IEER is intended to be used as a representation of part load performance

for energy comparisons of similar systems. For Variable Refrigerant

Flow (VRF) Multi Split systems AHRI Standard 1230 deﬁnes the process

to calculate IEER. In a most simplistic form IEER is calculated by

operating the system at 4 different capacities and applying a formula.

The basic calculation is as follows:

Some points to recognize from this calculation:

1. Full load EER (100% capacity) represents only 2% of

the overall IEER rating because the system would rarely

operate at this condition.

2. As overall capacity is reduced the system EER

increases signiﬁcantly.

3. An ECOi system operating at 50% part load could

result in an efﬁciency increase of more than 70% over

the rated full load EER value.

4. Your actual efﬁciency could exceed the IEER rating

depending upon equipment sizing, environment and use

of the system.
