|| HVAC SOFTWARE PROGRAMS:
Building heat losses and air conditioning for any type of construction for walls, windows, floors & ceilings. Heat required for infiltration/ventilation air. Psychrometric properties of air-vapor mixtures
This HVAC software system consists of these programs:
- Building heat losses and heat required for infiltration and ventilation air for any type of building construction. 113 different constructions with overall R and U values are programmed. Windows, exposed walls, cold partition walls, ceilings, floors and ventilation air requirements are computed separately for each room and totaled for all rooms in the building.
- This program is suitable for initial estimates of air conditioning requirements for flat roof buildings, including heat gain from infiltration/ventilation air, lights, people, appliances, motors, etc., located in the conditioned space. The program considers one building as an entity, with north, east, south and west exposures. Any wall can be omitted, such as if one wall is connected to another building. The roof is considered flat, but can be sloping in any direction. Shading factors are not considered.
- The PSYCHART program contains 9 selections as follows:
No.1 Non-flow steady state condition (input 2 known conditions, compute 7 unknown psychrometric
No.2 Mixture of two air streams (input two air stream flow rates conditions, compute the mixture properties)
No.3 Sensible heating process (no water is added or removed)
No.4 Sensible cooling process (air stream cooled to above the dewpoint)
No.5 Cooling and dehumidifying (both sensible & latent heat changed)
No.6 Evaporative cooling process (cool adiabatically-total heat remains constant)
No.7 Heat/Humidifying process (add sensible heat and/or moisture via water spray, steam to an air stream)
No.8 Industrial drying process (evaporate water from a product with chilled or heated air)
No.9 Air conditioning process ( cool, dehumidify, reheat psychrometric properties of a conditioned space)
