Branching

Combination of line and header branching is highly ﬂexible. This allows for the shortest design route possible, thereby saving on installation time and cost. Line/header branching after header branching is only available with Toshiba Super MMS.

 Compact

The design of the modular Toshiba Super MMS outdoor unit allows for easy unit manoeuvring into

any standard lift. Its compactness also allows it to be easily installed in limited spaces.

 Largest system capacity

Toshiba Super MMS can be combined up to 48 hp (135 kW) as one refrigerant system.

 Energy saving design

The units have the best energy efﬁciency ratio of any VRF unit. Compared with a conventional chiller

fan coil system, a large energy saving can be realized.

 Advanced bus communication system

Wiring between indoor and outdoor units is a simple 2-wire system. The communication address is also automatically conﬁgured. A default test mode operation is available.

 Self-diagnostic system

Comprehensive troubleshooting code enables quick identiﬁcation of problems arising.

 High lift design

An equivalent pipe length of 175 m and vertical lift of 50 m are possible with the Toshiba Super

MMS. The vertical lift between indoor units of 30 m is the highest in the industry. This allows for greater ﬂexibility in the location of the system.

 Multiple indoor units

Indoor units with different capacities and conﬁgurations can be combined up to 135% of the

outdoor unit capacity. A maximum of 48 indoor units can be combined with the 30-48 hp outdoor units.

 Intelligent control

Toshiba Super MMS intelligent controls and modulating valves deliver the required capacity, in

accordance with the load variation from 50% to 100%. The intelligent controls and modulating valves limit or increase the cooling capacity dynamically so

humidity and temperature are kept in the comfort zone.

 Wide control applications

Artiﬁcial Intelligence Network system

• Central control and monitoring system available

• Weekly schedule operation through weekly timer

Integration with a Building Management System (BMS) is available.

The unit can be operated even if outdoor temperature falls to -20°C. However, the warranty only covers operation down to -15°C, as lower temperatures are outside the operating range.

When the outdoor air temperature falls to below

-15°C, unit operation may reduce the product life.

Example of equipment selection

The following shows an example of equipment selection based upon a building model.

Fig. 1 - Overview of building model

Outside view Floor conﬁguration

Small meeting room Executive rooms

Ofﬁce rooms (Entire ﬂoor)

Ofﬁce rooms

Stores

Non-air conditioning zone

• Steel frame, reinforced concrete building, four ﬂoors above ground. Total ﬂoor area : 415 m²

Outdoor unit is installed on the roof.

• Indoor design conditions:

Cooling: 27.0/19.0°C db/wb. Heating: 20°C db

• Outdoor design conditions:

Cooling: 35°C db (standard condition). Heating: 3°C wb (standard condition: 6°C wb)

Selection criteria for each ﬂoor

1F: Outdoor unit capacity exactly matches the total indoor unit capacity.

Total indoor unit hp = Outdoor unit hp Indoor: 2.5 hp x 2 units + 3.2 hp + 2 hp = 10.2 hp

Outdoor: 10 hp Same capacity

2F: Outdoor unit capacity matches the potential total indoor unit capacity with the possibility of future

extension.

Ofﬁce rooms 2 and 3 are to be used as warehouses at ﬁrst, so air conditioning is not necessary at present.

However, there is a plan to convert them into ofﬁces, so an outdoor module with extra capacity is required.

Piping/wiring are carried out. Indoor unit is not yet installed. When the rooms are used as an ofﬁce later, the indoor unit is installed.

3F: One indoor unit is connected to one outdoor unit.

The outdoor module should have sufﬁcient capacity to cover the peak demand of the indoor unit connected.

4F: Consider the diversity factor and have the outdoor module match 135% of indoor unit capacity.

This is a typical matching of indoor/outdoor units for a Super MMS system.

• Total indoor unit hp > Outdoor unit hp

• Select each indoor unit based on individual peak room load.

Indoor: 2.5 hp + 2.5 hp + 2 hp + 2 hp (capacity difference in each room) + 1.3 hp =

10.3 hp (different capacity) Outdoor: 8 hp (different capacity)

• The cooling load proﬁle needs to be taken into consideration.

Procedure and result of equipment selection

1. Procedure of equipment selection

a. Calculate cooling for every room. b. Select an indoor unit to match the cooling load for every room from the table on page 10. c. Select the outdoor module to match the indoor units selected in point b. Select the outdoor modules

based on the critical factors and the combination rule. Choose a tentative outdoor module that will match the indoor units, and check whether the selection agrees with the combination rule. Perform the capacity correction based on the pipe length, system lift, indoor set temperature, outdoor temperature.

Then, make sure the corrected system cooling capacity satisﬁes the cooling load.

Example: Equipment selection based on system load proﬁle

Since the ﬁve rooms on the 4th ﬂoor face different directions, their hourly cooling load proﬁle will also be different. We select each indoor unit based on the individual room peak load. However, we need to use the total load proﬁle on the 4th ﬂoor as a base to choose the outdoor module.

5. Refrigerant piping design

1. Warnings on refrigerant leakage

Check of concentration limit

The room in which the air conditioner is to be installed requires a design that ensures that the concentration of refrigerant gas will not exceed a set limit if there is a leak.

Refrigerant R-410A which is used in the air conditioner is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws that protect the ozone layer. However, since it contains more than air, it poses the risk of suffocation if its concentration should rise excessively. Suffocation from leakage of R-410A is almost nonexistent. With the recent increase in the number of high concentration buildings, however, the installation of multi air conditioner systems is on the increase because of the need for effective use of ﬂoor space, individual control, energy conservation by curtailing heat and carrying power, etc.

Most importantly, the multi air conditioner system is able to contain a large amount of refrigerant compared with conventional individual air conditioners. If a single unit of the multi air conditioner system is to be installed in a small room, select a suitable model and installation procedure so that if the refrigerant accidentally leaks out, its concentration does not reach the limit (and in the event of an emergency, measures can be made before injury can occur).

In a room where the concentration may exceed the limit, create an opening to adjacent rooms, or install mechanical ventilation combined with a gas leak detection device. The concentration is as given below.

Total amount of refrigerant (kg)

Min. volume of the indoor unit installed room (m³)

≤ Concentration limit (kg/m³)

The concentration limit of R-410A which is used in multi air conditioners is 0.3 kg/m³.

Note 1: If there are 2 or more refrigeration systems in a single refrigeration device, the amounts of refrigerant should be as charged in each independent device.

e.g. charged amount (10 kg)

For the amount of charge in this example:

• The possible amount of leaked refrigerant gas in rooms A, B and C is 10 kg.

• The possible amount of leaked refrigerant gas in

Room A

Room B

Room C Room D Room E Room F

rooms D, E and F is 15 kg.

Note 2: The standards for minimum room volume are as follows: (1) No partition (shaded portion)

(2) When there is an effective opening with the adjacent

room for ventilation of leaking refrigerant gas (opening without a door, or an opening 0.15% or larger than the respective ﬂoor spaces at the top or bottom of the door).

(3) If an indoor unit is installed in each partitioned room and

the refrigerant piping is interconnected, the smallest room is the critical room. But when a mechanical ventilation device is installed in combination with a gas leak detector in the smallest room where the density limit is exceeded, the volume of the next smallest room is used.
