### 2.6.3. Description of compartments – creating of new compartments and their general data

A new tabular flat is created similarly to partition, using the keys F7 or INS (to insert a compartment in selected area). Description of compartment is performed analogous to description of storeys. Method of use of window „Building structure: Compartment” is very similar to method of use of window for partitions edition. It consists of two parts: general data of compartment and table of partitions in compartment.

General data of compartment can be completed by entering them into edition fields or selecting from a pop-up list.

In field „Number” enter an identifying name and - if you want - add a comment to the name in field „Description”. Compartments are named automatically according to name pattern defined in program – with following numbers. The User can give them his own numbers or enter a description.

In field “Compartment type” select an appropriate type compliant with compartment’s destination. There are over dozen types available and to each type is assigned a temperature value and the value of minimal, hygienic air stream and stream of air exhausted mechanically from compartment. It is possible to change the assigned values for values known to the User, occurring in project.

If in project the ventilation air streams should be determined on the basis of ventilation air balance (see calculation method - APPENDIX B. APPLIED NORMS AND CALCULATION METHODS , then it is necessary to declare mechanical exhaust ventilation or/and blow ventilation as well as windows/external doors. Now the streams of air flowing from outside into compartment as a result of exhaust mechanical installation can be calculated. Because the ventilation air balance includes whole building, the balance includes all compartments of this building, both heated and non-heated.

For compartments not utilized permanently the ventilation does not have to be declared – just enter in field “Vexh – exhausted air stream” the value “0”.

Because the temperature value is completed automatically on the basis of compartment type, the fields „As – area of compartment in light“ and others, depending on the calculations option and type of used external partitions are still to be edited. More information to this you will find in chapter 4.5.3.1.

Field „Thermal zone” is available only for calculation of seasonal energy demand. Compartments are to be assigned to thermal zones in project data position „Thermal zones”. Definition of belonging to individual thermal zones has been described in chapter 2.8.

Fields filled in with yellow colour with attached icon are calculated by the program automatically according to data from other fields. That are: “hf” height of compartment in light, “V” cubic capacity of compartment, “Ssz” external walls thickness for floors on the ground (in case of detailed calculation method of heat loss to the ground), “ΔφRH” temperature drop in the stage of reduction in case of declaring of interruptions of central heating system operation and “n50” multiplication factor of exchanges at difference of 50 Pa. Availability of individual fields depends on selected calculation option. The User can impose these values clicking the icon . Cubic capacity of building is always calculated automatically by the program on the basis of data.

! Non-heated compartments are determined by deselecting of field “Heated compartment”. That means, that inner temperature in non-heated compartment will be calculated by the program according to thermal balance.
