Presentation on theme: "SINGLE SPLIT INVERTER AIR-CONDITIONER"— Presentation transcript:

Next we will look at new single split package air-conditioners of MHI in 2008. More important, we will have a new designed indoor unit this year, the new ceiling cassette -4way- indoor unit FDT, which will replace the present one. ver.4 1

2 Features of Inver type Air-conditioners
Energy saving --- Part load COP > Full load COP --- 2. Comfort operation 3. Quiet operation 4. Caring for the Environment --- R410A ---

3 Operation pattern 1. Conventional unit (Constant speed compressor)
Set Temperature ON OFF ON-OFF operation energy loss (1) Inrush current (2) Re-evaporation of condensed water from the heat exchanger

4 Operation pattern 2. Inverter unit (Variable speed compressor)

5 Inverter Series MICRO 7.1kW (3HP) ~ 25.0kW (10HP)
X Firstly, let’s look at the line-up of our new PAC. We have a new model for 1.5, 2.0 & 2.5HP outdoor units, ZIX-S, which is the replacement of the previous SRC**ZHX-S. X X 5 5

7 Model Name For example, F D C 140 V N X
X hyper ,Hi EER /- micro series Power source N: 1 phase / S: 3 phase Symbol for inverter model for PAC Capacity code (14.0kW) As you may noticed, our new model names are a bit different from the previous FD series. For example, the 6HP model FDC140VN/S. Letter FD, keeping the same meaning of the existing one, shows the symbol of single split PAC. Letter C is the symbol of outdoor unit. The digits after C show the nominal capacity of the unit as we mentioned just now. As for 8HP unit, 200 means 20 kilowatts, and 6/5/4 HP models respectively show 140/125/112 in their model names. 3HP equals to 7.1 kilowatts which show 71 in the model name. Letter V is the symbol of inverter compressor. Letters N/S mean the different power source. N means single phrase and S means three phrases. Symbol for outdoor unit Symbol for split PAC 7

FDC71VN, 1 ph power source, has the appearance as the upper picture shows. FDC100, 125 & 140 have both 1 ph and 3 ph, and all of them appear as the same exterior. FDC200VS & FDC250VS, the 8 & 10HP models, with 3 ph power source only, have twin fan side outlooks but different heights.

10 IndoorUnit :

11 For European countries
Indoor Unit : FDT -4-way Ceiling Cassette FDT- Industry Leading COP all models cleared CLASS A Next, I would like to introduce the new ceiling cassette -4way- indoor units, which have realized industry leading COP and cleared Class A standard with the highest energy saving level. I will start with the new features, following by the new designed air flow control, improved air-conditioning feeling and new remote controller. For European countries 11

12 "New" Design Ceiling cassette -4way- type
Ceiling Cassette : FDT 1-1: Individual flap control system "New" Design Ceiling cassette -4way- type According to room temperature conditions, air flow in four direction can be individually controlled by four flaps. New air outlet design brings sufficient air flow and long of air flow throw is realized. Current New

13 Efficiency is increased by 30% !!
Ceiling Cassette : FDT 1-2 : Compact but High COP # Thin height Newly designed of heat exchanger changed from 2 separate assemblies to 1 single assembly, the height of indoor unit was reduced drastically. Current # High efficiency New design brings, - Reduction of air flow pressure loss (=Decrease of Fan motor load) Using high efficient piping, high performance heat exchanger, - Increase in heat transfer efficiency Efficiency is increased by 30% !!

14 1-3 : Installation workability
Ceiling Cassette : FDT 1-3 : Installation workability 2. Easy checking of drain pan Easy checking of drain pan condition by removing corner lid only 1. Arrangement of installation balance of indoor unit Checking from access ports with detachable covers at each corner without removing a panel 3. Joint stopper Workability is improved by applying temporally joint stopper for panel.

21 Remote Controller Adapter
Optional Kits Option Name Model name Usage Remark Remote Controller Adapter SC-BIK1-E Connect with wired remote controller for RAC for SRK**ZG-S, to connect RC-E1R SC-BIKN-E for SRK**ZHX & ZIX-S to connect RC-E3 Superlink Adapter SC-AD-ER Connect Wired PAC & RAC with Superlink for 3-wire remote controller unit SC-ADN-E for 2-wire remote Remote Sensor SC-THB-E3 Change to the remote sensor from original intake air temp sensor for all new indoor unit (KX6,PAC) As we have mentioned earlier, RAC&PAC models can be connected into the superlink network and work together with our VRF system in the same superlink network as well. But some interfaces will be needed for the connection. Here is the list of optional kits, which is using for RAC&PAC models connection to superlink network. There are three different models. Remote Controller adapter will be applied when RAC units are needed to be controlled by wired remote controllers. SC-BIK1-E is using for SRK**ZG-S models controlled by the old RC-E1R, while SC-BIKN-E is connecting SRK**ZHX-S or the new SRK**ZIX-S models to the new 2-core controller RC-E3. Superlink adapter SC-AD-ER & SC-ADN-E are using for RAC/PAC systems to connect into superlink network. SC-AD-ER is used for the previous superlink 1 and 3-core wiring remote controller RC-E1, while SC-ADN-E is used for the new superlink 2 and 2-core wirings remote controller RC-E3. Remote sensor SC-THB-E3, which is a wildly used remote sensor, can change to the remote detected temperature instead of the original temperature of intake air. It is available for all of our new KX6 & PAC indoor units.

22 Superlink Network Structure with PAC & RAC
SC-SL1N-E KX6 Series RAC series (SRK50/60ZHX-S) Superlink Network (Superlink II) SC-BIKN-E Here we can see the superlink network structure including KX6, PAC & RAC. As we all know, the new superlink network applies 2-core wirings connecting outdoor unit, indoor units and centralized remote controllers as SC-SL1N-E & SC-SL2N-E. RAC series such as SRK50/60ZHX-S are using 3-core wirings for connecting o/u & i/u. As we mentioned in the previous slide, SC-BIKN-E should be connected as an adapter when RAC model is controlled by RC-E3. When RAC is connected into the new superlink network, it must be connected through SC-ADN-E to the new protocol network, and 2-core wiring is applied. In terms of PAC series, 3-core cable is using between the outdoor unit and indoor units. Again, same as RAC units, SC-ADN-E should be connected between PAC units and superlink network. 2-core wirings are applied. Now let’s look at the detail of each kit. SC-SL2N-E SC-ADN-E SC-ADN-E SC-ADN-E 22 22

23 Wired Remote Controllers Can Be Connected
Connections with Wired Remote Controllers Wired Remote Controllers Can Be Connected Models Interface Wired Remote Controller SRK63/71ZE-S1 Not Required RC-E1 SRK63/71HE-S1 SKM60/71ZG-S SRRM, STM SRK20~50ZG-S SC-BIK1-E SKM20~50ZG-S SRK50~60ZHX-S SC-BIKN-E RC-E3 SRK20~60ZIX-S SC-BIKN-E RC-E3 SC-ADN-E Superlink II Network Wired remote controller can be connected to RAC units with the interface SC-BIKN-E. SRK63/71ZE-S1, SRK63/71HE-S1, SKM60/71ZG-S & SRRM, STM models don’t need interface to be controlled by RC-E1, the previous wired remote controller. ZG series from 20 to 50 of SRK & SKM models need to be connected with SC-BIK1-E when controlled by RC-E1. When connecting with the new wired remote controller RC-E3, it is necessary for SRK50/60ZHX-S & the new series SRK**ZIX-S models to be connected with the new superlink protocol’s interface kit SC-BIKN-E. As we have seen, when RAC&PAC units connected into superlink 2 network, both SC-BIKN-E & SC-ADN-E are needed to connect with the indoor units. Can Be Connected Into Superlink-II Models Interface Wired Remote Controller SRK50~60ZHX-S SC-BIKN-E & SC-ADN-E RC-E3 SRK20~60ZIX-S 23

Cable 8m Exterior Dimension (H×W×D) 70 X 25 X 15 mm Color Ivory White Accessory Parts Sensor box Cable, Tape, Band Screw, Installation manual Another optional kit remote sensor SC-THB-E3, as we explained earlier, could be using when it is necessary to change the original intake air temp sensor to the remote one. It is only available for KX6 and new PAC units. The original intake air temperature sensor now could be changed to the cable connection, of which max length could be 8 meter. Or change to selectable from indoor side of remote control. Exterior is described as these dimensions, 70mm’s high, 25mm’s wide and 15mm’s deep with the colour of ivory.
