Samsung DVM S Multi-Zone Air Conditioning Design Tools
The multi-zone air conditioning system can be used not only in large projects, but also in individual construction. The pipelines have small diameters, there is no need to provide additional technical rooms for the equipment due to the usable area of the house. The outdoor unit DVM S has a low noise level and, if desired, can be removed from the house and separated from the site by a soundproof partition. Minimal maintenance, full-featured self-diagnostics and the ability to receive fault messages on a mobile phone minimize the cost of operating a multi-zone system. In the conditions of suburban housing, when it is removed from the city infrastructure and calling the representatives of technical services requires a rather large investment of money and time, these advantages are very important.
The installation of any engineering system begins with the design stage. The air conditioning system DVM S has a high degree of factory readiness. This facilitates the engineering task of selecting the required equipment.
To speed up the design of the air conditioning system and reduce selection errors to zero, the specialized software “DVM Pro” has been developed. The program is distributed free of charge and can be downloaded from the official website.
The DVM Pro software is available for work in two modes. The first mode is SALES. This is a simplified selection of equipment with the output of specifications and connection diagrams in the Word file format. However, it is sufficient to accurately select all components and calculate the quantities of consumables. The second CAD mode is an add-on for AutoCAD and works in AutoCAD or AutoCAD Mechanical, version not lower than 2010. When working with the program in CAD mode, the finished drawing of the object is supplemented with an air conditioning system.
Selection of equipment using the "DVM Pro" program consists of 7 stages
1. Entering the initial design data (climatic parameters, object parameters)
2. Selection and placement of indoor units and additional accessories.
3. Selection and placement of the outdoor unit.
4. Laying the route of freon pipelines, placement of splitters
5. Automatic check of the system for restrictions on route lengths and elevation differences
6. Design of the drainage system
7. Selection of the control system
As a result, the user receives a full-fledged project with output data containing models of outdoor and indoor units, models of branching units, lengths and diameters of pipelines, routing of drainage and freon pipelines, calculation of the required additional amount of refrigerant.
Benefits of using a custom design program
The designer may find it superfluous to install additional design tools for the job. In fact, installing additional software takes a minimum of time and provides maximum benefits. What are these benefits?
Firstly, these are automatically loaded drawings of all elements of the air conditioning system. You can select the model of the indoor unit directly, or the program will offer you models and select the number of indoor units based on the specified specific heat flux per 1m2. The only thing the user needs to do is to select the area of the room for air conditioning with the mouse.
The DVM Pro program contains tables of block performance. When creating a project, the user of the program sets the climatic parameters for the premises and data on the outside temperature and humidity. Using the specified parameters, the program will calculate the actual performance of the unit and compare it with the required one. When designing the refrigerant line, the program takes into account the drop in system performance from the length of the line and the difference in height. With the length of the route and the actual temperature and humidity different from the nominal values, the refrigerating capacity of the air conditioning system can be adjusted up to 20-25%. If you select the air conditioning system manually and did not use the correction tables and graphs, this will negatively affect the correct choice of unit capacities.
DVM Pro takes into account all the above changes. She will promptly warn the user about the need to re-select blocks and suggest suitable model options. DVM Pro gives you the advantage of using the automatic piping option and then only adjusting the routing if necessary. The type of splitters and the diameter of the pipelines are automatically calculated based on the total capacity of the units and are indicated in the drawing. Upon completion of the project, a BOM is generated containing the main characteristics of the system and the number of components. The user also receives a diagram of the refrigeration circuit with the distribution of indoor units by floor.
An example of designing a multi-zone DVM S system for a country house
For air conditioning, a project of a two-level residential country house was chosen. The first floor is a public function and is divided into two blocks: public (living room and kitchen-dining room) and technical block (boiler room, garage, technical premises, sauna). The public block has the most free layout with a minimum of partitions. On the second floor there is a quiet area (bedroom area).
Panoramic perimeter glazing of the living area of the first floor visually and communicatively connects this area with the surrounding landscape, and the hearth set in the middle creates coziness. Each segment of the stained-glass window from the outside is provided with vertically closing and opening roller shutters. Roller shutters consist of individual lamellas 35 mm thick and insulated with expanded polystyrene. From the outside and from the inside, the lamellas are finished with natural veneer. By adjusting the position of the blinds from inside the house, you can change the nature of the interior space: from open around the entire perimeter to private; you can also change the thermal circuit of the house, which is important in winter. In addition, roller shutters are also protection from excessive sunlight. Together with the Samsung air conditioning system, these techniques allow you to achieve the desired microclimate, physical and psychological comfort.
Maintaining comfortable air conditioning conditions is required in 6 rooms on the first and second floors, with a total area of 201 sq.m. The required cooling capacity is estimated at 29.3 kW. Two types of indoor units have been chosen for air conditioning the premises. Cassette four-way and wall. Cassette units of Samsung multi-zone air conditioners are installed in rooms with a ceiling space. In the rest of the premises, wall-mounted indoor units are used for air conditioning. Cassette blocks fit organically into the design of the house in the hi-tech style.
They provide an even distribution of air in 4 directions. Each blind of the unit is individually adjustable from the control panel. Ceiling height for even temperature distribution over the height of the room can be up to 4.6 meters.
The advantage of the cassette 4-way unit is the possibility of using faceplates of various colors and designs. It can be either imperceptible or vice versa, stand out as a piece of furniture. An important feature of the cassette unit is the ability to connect an additional air duct for mixing fresh air. Thus, it is not necessary to install separate air supply grilles to ensure the required air exchange. The built-in drain pump makes it easy to drain the condensate. The cassette indoor unit can be optionally equipped with the Virus Doctor air handling unit. This is a Samsung Electronics patented technology for neutralizing viruses, bacteria and allergenic compounds.
In the process of designing an air conditioning system using flush-mounted units, there may be a problem of lack of height in the under-ceiling space. The cassette four-flow DVM S unit with a capacity of 9 kW has a height of only 20 cm. With a very low height of the under-ceiling space, it is possible to use a cassette single-flow unit with a height of 13 cm. The limitation on its use imposes a maximum capacity of 3.6 kW, whereas cassette dashes of the three-flow unit have a capacity range from 2 to 14 kW.
The outdoor unit is selected from the calculation of the load of 104% of the capacity of the indoor units. Model AM100FXVAGH.
The outdoor unit is installed in the technical room of the first floor with air discharge to the street through the duct. The pressure characteristics of the outdoor fan provide for such installation. The advantage of the proposed installation option is the lack of visibility of the block and a decrease in the noise level when being on the site near the house. The area of the room occupied by the block is less than 1m2. The unit is accessible for maintenance from the front. The minimum free space on the rear side of the unit is 0.2 m and on the sides by 0.3 m.
Second floor, sleeping area, air-conditioned with internal wall-mounted blocks. Their advantages are low noise level and additional functionality, such as a comfortable sleep mode and a high-purity air filter.
Full HD high purity filter traps smaller dust due to the finer filter mesh while maintaining the required air flow. The technology used by Samsung Electronics has resulted in a thin and durable filter mesh material. The filter is designed for the entire life of the air conditioner, does not require replacement and is easy to maintain.
Features of using the DVM Pro design program
To design an alignment in a building, you need to place all the floors in one drawing and convert to one layer. The program recognizes floors by the location of indoor units. At the initial design stage, the user sets the number of storeys of the object and the height of the floors. When selecting an indoor unit, the program asks about belonging to a floor and thus binds the unit to a specific location. Interfloor transitions are specified by a transition point. A mark is placed at the place of transition from floor to floor. Thus, the program identifies different floors in the same drawing by the transition points pre-assigned to the floors.
As a result of the work carried out, we obtain a summary specification, a table of characteristics and tables with an explanation of the designations in the drawing.
If necessary, you can choose a central control system. Additionally, it is possible to integrate it into the overall intelligent home control.
For a detailed study of the program's features, you can use the user manual or video tutorial.
