Fresh Air Intake Indoor Unit Type

1. Outline of fresh air intake unit

• Type: Concealed Duct High Static Pressure type

Three models (5HP, 8HP, 10HP) are prepared.

• Connectable outdoor unit

Three series (MMY-MAPXXXXT8, MAPXXXXHT8, MAPXXXXHT7) of Cooling/Heating selecting Super module multi type outdoor unit.

• Corresponding system

Corresponds to a system in which there are the fresh air intake units and the indoor air conditioners. (For the fresh air intake units, up to 2 units for one system and also within 30% to capacity of the connectable indoor air conditioners are allowed.)

• Definition

The fresh air intake unit means an air controller for taken-in fresh air. Intake of the fresh air often influences on the system so that the normal control of the air conditioner becomes difficult or gives a large load upon air controller and cooling performance. Therefore it is frequently adopted to handle the fresh air to a certain condition before the fresh air will enter in the main air conditioner. This handling device is called a fresh air intake unit.

NOTE:

The Fresh Air Intake unit is an air conditioner provided to handle the fresh air load and is not to control the room temperature. For correspondence to the load of the indoor air controller, set an air conditioner separately.

2. System able to be combined

The fresh air intake unit is connectable to S-MMS (Super Modular Multi system). However this is not connectable to S-HRM (Super Heat Recovery Multi system).

0.5m or less

80 to 100% to capacity of the outdoor

Keep the height difference between the fresh air intake units to 0.5m or less.

Up to two fresh air intake units occupy 30% or less

· The fresh air intake unit is usually used together with the indoor units on one line of the multi system.

The fresh air intake unit only cannot be connected.

· The total capacity of the indoor units and the fresh air intake units is restricted to 80% to 100%

against the capacity of the outdoor units. (This restriction should be strictly kept for correct control of the refrigerant.)

· Up to two fresh air intake units can be connected on one line of the multi system.

The allowable total capacity of the two fresh air intake units shall be 30% or less against the total capacity of the indoor units (including the fresh air intake units).

Connection which stretches over two floors is unavailable

Height difference:

0.5m or more

3. Use Conditions

· In COOL mode, if temperature of the fresh air is under the setup temp. +3°C, FAN status is

automatically made. When temperature of the fresh air is under 19°C, FAN status is also made regardless of the setup temperature.

· In HEAT mode, if temperature of the fresh air is over the setup temp. -3°C, FAN status is

automatically made. When temperature of the fresh air is over 15°C, FAN status is also made regardless of the setup temperature.

• Operable mode and discharge temp setup range

• Special mentions

1. The fan operation of the Fresh Air Intake unit stops during defrosting. However the fan operation is enabled to continue by selection.

2. When a central controller is used, divide zone setup of indoor air conditioner and fresh air intake unit.

3. The standard is to control the discharge temperature. However the priority is given to the capacity control for the indoor air conditioner in a system in which the normal indoor air conditioner concurrently operated.

4. The fresh air intake unit cannot be connected with remote controller group of the indoor air conditioner.

5. In heating operation, if the temperature is below –5°C, the operation stops automatically. (FAN stop) (To protect the refrigerant cycle)

6. In cooling operation, if the temperature is below 5°C, the operation stops automatically. (FAN stop)
