1. Introduction

Xpress has some limitations on selection.

1-1. Purpose of Xpress

1-2. Limitations on Selection

Xpress is a selection software for VRV and CMSQ systems.Xpress helps your quick selection for quotation with easy operation.

1) The capacity correction factors corresponding to height difference betweenoutdoor unit and indoor unit are simplified. They are used depending on therelative position of the outdoor units such as Higher, Same level, orLower.

2) Though you can input the exact height of the outdoor units, the value is usedonly for checking the limitation of the height difference.

3) Capacities are not completely equal to Engineering Databook.The Xpress uses an approximation formula made from the capacity table tocalculate capacity. Differences should be less than 1%.

4) Design temperature can be inputted outside the scope of the capacity tablerange. Data input only has a range check. The actual check of thetemperature to be within the capacity table range is done during the selection.Values outside this capacity table range result in an error message on theoutdoor unit.

5) The number of the control groups is not considered.The number of control groups are limited by the number of controllers or less.

6) The sensible capacity is calculated from the actual total capacity, the bypassfactor and the fan airflow at high speed. Therefore, this calculated capacitymay differ slightly from the sensible capacity value of the databook.

7) The order of indoor units is determined by the piping layout. Therefore, thewiring diagram does not always correspond to the field (actual) diagram.However, they can be set equal by moving indoor units up and down in thetree view.

8) The order of outdoor units does not affect piping and wiring diagrams.If you change the order of outdoor units, the order will be changed on thereport file.

9) Some options are not displayed on the [Piping] tab and the [Wiring] tab.

10) We strongly advise to use the function Enter individual piping lengthsmanually instead of relying on the automated piping length calculation byfilling out the Equivalent piping length and First branch to indoor units.The automated calculation may result in a rough estimation. Therefore, thecorrection of the capacity of the indoor units and the size up of the pipingdiameters may not be accurate. Also, in this case there is no calculation ofthe additional refrigerant charge.

5-2-1. Automatic Selection

The combination of indoor designconditions will depend on yourpreference settings (see 4-6).The temperatures should be choseninside the scope of the capacity table.

(5) (6)

If sensible heat capacity or heating capacity is not required, put zero.Xpress selects the indoor unit that satisfies all required capacities.


1) Uncheck the [Manual Selection]check box

2) A name and/or room (optional) canbe assigned to the indoor unit.When multiple indoor units areassigned to the same room,Xpress will select the indoor unitsin a way that the sum of the indoorunits covers the required

capacities.3) Select the family (type) of the

indoor unit from the drop-down list.

4) Input design criteria (condition) andrequired capacities (loads).

5) Click the [Add] button after all conditions have been filled in.A new indoor unit is added to the indoor unit list on the [Indoor Units] tab.Repeat the procedures (1) through (5) until all indoor units are added.

6) Click the [Close] button to finish the indoor unit selection.The [Edit Indoor Unit Selection] window is closed, and the [Indoor unit] tab

page appears again.

Note:

[Select Options] button (7) is unavailable because an indoor unit has notbeen determined yet. After connecting to the outdoor unit, the indoor unit isdetermined and the button will be available.

Note:Technical cooling is only available for the Heat Recovery Range.

When the "technical cooling" function is activated, the system can cool a roomwith an operation range starting at -20 C (instead of the default -5 C). Atypical application is the cooling of a server room. The only slightlydisadvantageous consequence is that the noise of the BS-box is a bit louderwhen technical cooling is activated.

To change the order of the indoor units, drag and drop units on theindoor units list window. For example, to insert Unit 1 before Unit 2,drop Unit 1 on Unit 2.The change of the indoor units order on the [Indoor Units] tab doesntchange the indoor units order on the other tab pages.

5-7. Change the Order of the Indoor Units

Note:You cannot move the unit to the last

position directly.To move the unit 1 to the last position,first drop the unit 1 on the last unit.

Then move up the last unit on the unit 1.

Note:When indoor units are connected directly to the outdoor unit, they can only

operate in cooling only mode.In this case, the caution icon ( ) will be displayed at the left side of the indoorunit icons and a caution message will be displayed at the bottom of the window.

Indoor units cannot be connected toheat recovery model outdoor unitsdirectly (except for cooling only mode).For heat recovery operation, a BS-boxis necessary.

The [Add BS] button ( ) becomesavailable when Heat Recovery familyis selected.Click the [Add BS] button to add a BS-Box to the outdoor unit.

Next, connect indoor units to the BS-box as described in section 6-4-1.

6-8. Change the Order of Outdoor Units

To change the order of outdoor units,drag and drop outdoor units in thesystem list window.

If you drag the outdoor unit onto anotherunit, it will be inserted before the otherunit.

To insert the [Out Hall1] before [OutRoom2], drop [Out Hall1] onto [OutRoom2].

To move to the last position, it takes 2steps.

First move the outdoor unit that you wantto move to the last position onto the lastoutdoor unit.Then move up the last outdoor unit.

Note:This change is only applied in the

[Outdoor Units] tab page.The outdoor units order in other tabpages dont change unless you deleteone.

6-9. Change the Order of Indoor Units

The order of indoor units is very important for the piping layout.Define the order in consideration of the actual indoor units grouping and pipinglayout.

To define the order, recommended basic rules are:

- Create indoor units groups (e.g. units for each room)- Change the order of groups based on the distance from the outdoor unit

(from the farthest group to the nearest group)- Organize the indoor units in the group, by number (name)


38/73

In the case of the next figure, recommended order is :

See section 7-3 for reference.

To change the order of the indoorunits, drag and drop indoor units inthe system list window.

To insert Unit 1 before Unit 2, drop

Unit 1 onto Unit 2.To move to the last position, dropthe indoor unit onto the outdoor unit.

Changing the order of indoor unitswill affect the [piping] and [wiring]diagrams.

Note:Changing the order in the

[Outdoor Units] tab page has norelation with the order of indoorunits on the [Indoor Units] tab page.The order should be definedaccording to actual layout.

Selection window, this box is already checked.

All pipes will be red, until a piping length has been entered, after which theyll becomeblue. When all piping lengths have been entered, the Piping not yet complete-message will disappear.

This can be done in multiple ways:

- Double click on a pipe - Right-click on a pipe andselect Enter Pipe Length

After double clicking or right-clicking the pipe, the [EnterPiping Length] screen pops up.

1) Enter the length of the pipe.

2) Enter the number of bends

7-4. Printing large piping diagrams

When the piping diagram is printed in the report, it is always printed shrink to fitpage. For VRV systems with many indoor units, this results in a report where

the names of the units are no longer readable. Therefore, it is possible to cut thediagram into several parts and label each part. Each part is then printed onanother page in the report, with its label in the sub diagram title.

The cuts need to be defined in the[Piping] tab. You can define a cut byclicking on the intermediate pipe partwhere you want to cut the diagram.Then right click and select EnterSubdiagram label.

The screen Enter Subdiagram Labelappears, which allows to enter a labelfor the subdiagram. Suppose we enterA.

After entering the label, click OK.The label A appears on theintermediate pipe that will be cut.

Enter the other cuts in the same way.It is advisable to create the .rtf-outputto see the result. If you are satisfiedwith the result, save your project. Thelabels are stored within the project.
