Energy saving

1. EER energy efficiency factor improvement

Compared to previous models (YKA), Mitsubishi Heavy City Multi VRF improved the EER energy efficiency coefficient in all 1-way and 2-way air conditioner from 8 HP to 60 HP.

2.  Strong quality for partial load 

Since the temperature difference between day and night is very high, the efficiency of the low load system is also significant. The compressor has made structural changes that maximize efficiency under low load relative to previous versions, enabling the machine to reliably maintain high efficiency across the year, including transfer times.

3. Energy-saving support 

In addition to energy savings due to changes in compressors, Mitsubishi Electric has also developed a feature to help conserve energy by setting up a DIP turn. This allows the system to operate well in a number of installation conditions. 

Regulation of evaporation rate: The rate of the refrigerant can be regulated by conditioning load during service. This makes the machine work effectively and uses fewer resources.

Normal mode: The evaporation temperature is kept constant and does not change with the conditioning load. Even under low load conditions, the evaporation temperature remains constant, resulting in wasted energy during operation at the partial load.

Intelligent control mode: Mitsubishi Heavy City Multi VRF Air-cooled systems supports evaporative temperature control by adjusting the evaporation temperature of refrigerant according to the needs of the air conditioning load. 

1. Fixed evaporative temperature control method

The evaporation temperature is variable and constant controlled. Selecting a higher evaporation temperature than during normal system operation reduces compressor load and improves operating efficiency.

2. Automatic evaporative temperature control method

The evaporation temperature is adjusted according to the conditioning load. When the room temperature reaches the set temperature, the evaporation temperature was increased to reduce compressor consumption to save energy. There are four levels of evaporation temperature that can be selected.

Control capacity when the outside temperature is high

1. The system can still operate when the outdoor temperature is 52 ° C

In areas with a dense outdoor unit density in a building, it is easy to cause wind that is the cause of the increase in the ambient temperature of the outdoor unit. Because the operating conditions of the Mitsubishi Electric City Multi VRF Air-cooled combination system  can be up to 52 ° C (125oF), the system still operates stably in this situation.

Analysis of cooling conditions (conditions: Outdoor temp = 35oC (DB), Room temperature = 27oC (DB)).

 

Install the outdoor unit in the rooftop: If the outdoor unit installation area is not well ventilated, the hot wind discharged from the outdoor units will not be released and will be kept around the outdoor units causing the wind-rolling phenomenon.

Install the outdoor unit on each floor: When the outdoor unit is installed on the balcony, the hot wind released from the outdoor units on the lower balcony can be captured by the upper balcony.

Suitable for the situation

Install the outdoor unit in locations such as balconies or between buildings where there is a tendency to cause wind distraction.

2. Support function when the system operates in cooling mode

Mode support cold capacity

As the outdoor temperature temperatures rise during air conditioning, the cooling power of the system begins to decline. Mitsubishi Heavy City Multi VRF Air-cooled systems are designed to assist in cooling capability by automatically raising the speed of the outdoor cooling fan when the outdoor temperature reaches 38oC. This tends to reduce the cooling power when the outside temperature is high, providing convenience for consumers.

Fast cooling mode

The compressor's rotation speed can be raised above standard within the first 30 minutes after start-up, which helps to build a fast and relaxing environment as customers return home or start working day. This mode also allows the air conditioning system to restart after power loss quicker than before.

Technology characteristics

All the main components of the Mitsubishi Electric CITY MULTI VRF air-cooled system show excellence in the technology field of Mitsubishi Electric. This makes the air-conditioning system highly energy-efficient, responsive to cold capacity when outdoor temperatures rise, and other innovations highly reliable.

Inverter Technology

Mitsubishi Electric is a manufacturer of electrical and electronic equipment, so the components related to inverter technology are developed and manufactured using the proprietary technology of Mitsubishi Electric.

The compressor changes the rotation speed to suit the need for cooling or heating in the room, so it consumes only as much energy as needed for operation.

When the inverter-controlled compressor operates at a partial load, the energy efficiency of the system is significantly higher than in the case of a compressor without an inverter.

Non-inverter compressors only operate at a 100% load, however, the full load frequency appears very year. Consequently, the inverter does not use an inverter that is not suitable for air-conditioning systems that require an energy-efficient operation.

Intelligent Power Module (IPM) is manufacture by Mitsubishi Electric.

The Intelligent Power Module is the main component in the inverter board that is installed in a compressor and is manufactured by Mitsubishi Electric. Also, IPM is a dedicated circuit that ensures excellent performance to create high-quality and high-efficiency inverter technology.

IPM technology ensures the air conditioning system works efficiently even under low load conditions and automatically controls the compressor to operate by the actual conditions, thereby helping to save energy for the air conditioner system.

Compressor

Various ports for liquid discharge 

Beside 3 traditional exhaust valves, the Mitsubishi Electric City Multi VRF Air-cooled combination system has an additional 6 solvent discharge valves, this is achieved under the cooling load to avoid undue compression. And to increase operational efficiency.

Concentrated winding systems 

Mitsubishi Electric has added a new technique to the production process that wraps copper wire around iron cores to manufacture a motor that is both lightweight and more powerful.

Improved high efficiency engine 

Although the engine core of the previous product line (YKA) also had a space between the insulating shell and the membrane, the Mitsubishi Heavy City Multi VRF Air-cooled combination system had a mask. Smaller insulation and inside of the insulating film. As a result, the copper winding area is raised by around 9%. The diameter of copper wire has since been increased by two sizes, decreasing the resistance of the wire. This helps boost engine performance and hence increases the efficiency of the compressor.

Oil heating system (electromagnetic induction)

To avoid the mixing of refrigerant and compressor oil when the air-conditioning system ceases operating, a head radiator must be used. Mitsubishi Electric uses an internal head heating solution using an electromagnetic induction technology (using a voltage that heats the coil of the compressor without regulating the compressor to operate) instead of using a heating resistor outside the compressor housing to minimize the energy loss. The oil heating system still stays in operation for 30 minutes after the unit stops and then turns on and off every 30 minutes. As a result, the standby energy consumption is smaller than before (the delivery of continuous electricity to the heating resistor).

* Usually, the compressor with an outdoor unit heater ceases operating to avoid the creation of a liquid refrigerant in the compressor, which helps shield the compressor from hydraulic effects.

Fan

The outdoor fan unit is new built to further boost cooling efficiency

New configuration decreases the energy consumption of the cooling fan. Besides, more efficient cooling allows the device to work stably as the outdoor temperature rises.

Heat exchange

Copper pipes in the outdoor unit are built with tight grooves to enhance heat exchange. 

The painted construction of the copper pipes in the outside unit raises the heat exchange region exposed to the refrigerant. The heat exchange method 
is more effective.

High reliability

1. Compressor 

The liquid and vapor refrigerant are separate before entering the compressor by a liquid separator to prevent hydraulic shock inside the compressor. Besides, compressors use low-pressure shell technology, so in case the medium is still a bit liquid, it is safe for the compressor because the solvent is not led directly into the compression chamber.

Low-pressure shell technology: Most parts of the compressor produces low-pressure steam refrigerant. Stopping the engine and the bearings from being heated by superheated steam. The liquid refrigerant is collect at the bottom of the housing, which decreases the rate of compressor damage incurred by hydraulic shock.

Usage of liquid separator: if the refrigerant does not evaporate in the indoor unit, any liquid persists in the compressor. This can cause the compressor to become loose, resulting in hydraulic shock damage to the compressor. To overcome this problem, Mitsubishi Electric uses a liquid separator to separate the liquid before it returns to the compressor, increasing the reliability of the air conditioning system. (* Over-filling of refrigerant leads to an excess of the separator tank capacity resulting in liquid returning to the compressor. Care should be taken and make sure the correct amount of refrigerant is loaded.)

2. Electrical equipment

Requires operation when the voltage difference rises or decreases by 10%: the operation of the device is assured when the voltage increases or decreases by 10% relative to the rated voltage.

The circuit board system is usually cooled: PCBs (circuit board systems) are equipped with a wide variety of electronic instruments. As the operating load increases, a solution for cooling the board is required. Mitsubishi Electric puts PCBs in natural airflow pathways that allow efficient cooling to sustain operational efficiency and improve the functionality of each electronic device.

Easy to operate: The electrical appliances and motherboards are concentrated at the top of the outdoor unit and can be easily opened for replacement when needed. Also, the compressor is located below in the right corner of the outdoor unit, so service technicians can easily perform maintenance from the front.

3. Anti-corrosion

Where an outdoor unit is mounted near a perimeter field, Mitsubishi Electric devices are capable of minimizing the corrosive effects of sea salt by using a special coating developed for the outdoor unit. 

* The result differs based on the location of the installation.

Circuit board coating: Circuit board circuits are covered by a polyurethane film coating to ensure sea salt corrosion resistance. 

* Basic model only covers minimal wiring.

The housing is covered with Polyester coating: To prevent corrosion in areas affected by wind turbulence, the outdoor unit housing is made of polyester-coated steel sheets by JRA 9002. The coating is used in Standard model and Model BS (Model against sea salt corrosion).

Fitted with a Blue-Fin coating on the outdoor heat exchange: the aluminum radiator fins in the outdoor unit can be degraded due to the effects of new field emissions (dust in the air) resulting in decreased capability and life of the outdoor unit. The Mitsubishi Electric City Multi VRF is fitted with a Blue-Fin coating which is resistant to this corrosion phenomena.

4. Operational support functions


When an indoor unit malfunctions, the M-NET system of Mitsubishi Electric allows the remaining indoor units to continue working without the need for any additional settings or controls to be mounted on the system. (* This feature is still supported for Model PUMY and PQHY)

Function to close the LEV indoor unit from outdoor unit via M-NET (CITY MULTI)

For hotel buildings: When the air conditioning system with one indoor unit malfunctions, the indoor units of the remaining rooms do not need to be turned off to repair the faulty indoor unit, this allows hotels continue to do business.

High flexibility in installation

1. Designing flexible signal line systems

Flexible architecture with M-NET: the device can be bundled at various levels to improve the versatility of signal wiring and is ideal for the complex design of the house.

2. Flexible installation of a static outdoor friction fan

You should select the correct static pressure level: the static pressure parameters of the outdoor fans have 3 levels to choose from: 0, 30, 60 Pa. This makes it easy to add exterior units on-floor or balcony in tall buildings.

3. Length of refrigerant piping

Establish versatility in the construction of solvent pipes to satisfy the needs of each building form. For CITY MULTI, pipes can also be used for large-scale structures.
