Cool Room Calc

Cool Room Calc 2.0 for Windows®

This computer program is designed for air-conditioned room cooling load calculations. It requires a minimum of input data to be entered, that are sufficient for most frequent tasks occurred in practice. The program can be used both by professionals and non-specialists in the field of air conditioning technology. The program works with dual units of measurement (SI and I-P).

ENCLOSURES

Room envelope insulation characteristics and number of insulation layers
Characteristics of each wall, ceiling or floor:
- internal - a partition, a ceiling or a floor
- external (light) - a wall or a roof
- external (medium) - a wall or a roof
- external (dark) - a wall or a roof
- external (attic) - a roof
- external (ambient) - a floor
- external (ground) - a floor
Adjacent space temperature for each wall, ceiling or floor
Percentage of each wall or roof incident irradiation
Room construction materials characteristics:

FENESTRATION

INPUT DATA:

Fenestration products (up to 8 simultaneously) characteristics
Places of fenestration products installation (walls or ceiling)
Apertures dimensions
Total quantities of fenestration products installed
Characteristics of exterior and interior shading devices
Percentages of shaded areas

REGIME

INPUT DATA:

Climatic characteristics of air-conditioned room geographic location
Room space air temperature setpoint
Room space air relative humidity
Room volume air ventilation rate
Minimal outdoor air supply rate
Room air ventilation description:
- natural
- forced
Room ventilation air temperature (forced ventilation)

Temperature of soil beneath the room floor
Maintenance (internal) heat gains as a percent or detailed from different sources:
- envelope cracks and other openings
- people (depending on their physical activity level)
- electrical office and household appliances
- miscellaneous sources
Safety factor

Data Bases

The program is supplied with the databases on elements of construction heat insulation, types of fenestration products and climatic characteristics of different geographic locations. The entries in these databases can be easily added, deleted and edited by the user.

INSULATION

PARAMETERS:

Insulation name
Standard layer thickness
Insulation material thermal transmittance coefficient

FENESTRATION PRODUCT

PARAMETERS:

Fenestration product name
Overall heat transfer coefficient (U-factor)
Overall solar heat gain coefficient (SHGC)

CITY

PARAMETERS:

City name
Geographic location latitude
Summer design air temperature and relative humidity

REPORT

The output of the program's work is a table of heat gains into air-conditioned room from separate sources, their ratios and also the total heat gain, as well as a table of heat loads grouped by source categories and their total including safety factor.

The program allows to enter information about the customer and the project, as well as to get on paper or in electronic form a printout with the calculation results.
