Air volume control technical manual

Indoor unit air volume can be controlled with a opening-closing of a damper by either an analog input (CN2A) or a

contact input (CN105) to the air conditioning unit.

With the PEAD series, it is possible to cut energy consumption by controlling not only the air volume but also the

compressor capacity.

■Corresponding model

Air volume can be controlled with the following models.

(1) PEAD-RP60,71,100,125,140JA(L)

(2) PEFY-P63,71,80,100,125,140VMA(L)-E

NOTE:

Air volume control with analog input 0-10V is not available with the following models.

(a) PEAD-RP35,50JA(L)

(b) PEFY-P20,25,32,40,50VMA(L)-E

1-1. Air volume control

Indoor air volume can be controlled in 10 different stages from V1 to V10 with analog input 0-10V from

the damper system controller supplied on site.

*Air volume rate shows the value without change in

the external static pressure. For values in different

external static pressure, refer to 3. Fan characteristic

curves for details.

1-2. Outdoor unit capacity control

With the PEAD series, compressor capacity is controlled in accordance with air volume level in 10

stages from V1 to V10.

With the PEFY series, compressor capacity will not be controlled because numbers of indoor units are

connected. However, it is possible to reduce energy consumption with a change in the air volume

leading to compressor capacity control due to a change in condensing temperature.

Air volume can be selected in the following order.

■Condition:

1. R1- R4 indicates the air outlet of each indoor unit.

2. R4 fully open at all times.

3. Air volume designed as R1: 5m3/min, R2: 5m3/min, R3: 7m3/min, R4:17m3/min.

■Selecting air volume stage V1~V10

Depending on the damper opening pattern R1-R3, patterns 1~8as in the below chart is available. The air volume

stage is selected from the fan characteristic curve. (Refer to [Fig. 1-4-3])

Choose the pattern closest to the required air volume and which the diagram exceeds.

Duct pressure drop depends on the site conditions. Shown here are temporarily numbers in case of external static

pressure 100Pa.

NOTE*1 In order to change functions 1~3from MAC-397IF-E, contact input from damper system controller is required. Only one of the functions 1~3is

available one at a time because setting is made by switching DIP-SW of MAC-397IF-E. Refer to the MAC-397IF-E manual for DIP-SW setting and

wiring.

Check air volume at each air outlet when R1-R4 is full open and set static pressure as target value. Then, analog

input to keep the static pressure at this target value even when either of the damper closes.

With MAC-397IF-E as in section 2-2, it is also possible to stop the indoor unit when all duct damper closes.

*Refer to the 1-3 for air volume differentials to prevent hunting.

With an analog input of 0-10V, indoor air volume can be controlled in 10 steps from V1 to V10.
