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

INPUT DATA:
  • Room walls orientation
  • Room envelope dimensions
  • 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:
    • light
    • average
    • heavy
  • Room floor shape description:
    • rectangular
    • L-shaped

 

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)
  • Room ventilation air relative humidity (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.

 

There is a comprehensive context-sensitive help file.
