Abstract:
Conditioning chamber is an electromechanical equipment based on the working
principle of refrigeration cycle. The equipment is used to create an internal atmosphere
where temperature and humidity can be controlled according to the desired testing
conditions. The device is used for storage of different materials in order to bring them at
a desired temperature and water content level.
HVACR system manufacturing industry is an upcoming technological field with
ample space for work in various areas. The local industry is dependent upon designs
provided by international conglomerates. There is a need to gain knowledge of the
design techniques based upon which selection of equipment is undertaken from
renowned manufacturers worldwide and also enhance the indigenous potential in
relevant fields.
The civil and government organizations involved in development of these
equipment are lagging in requisite knowledge of design techniques and are dependent
on systems offered in the market.
This research work addresses the issue and provides an in depth knowledge of
the design technique for manufacture of custom design HVACR system. The study lays
out the basic parameters as a foundation stone of design and undertakes calculations
for ascertaining the cooling load, heating, humidification and dehumidification to form
various building blocks. It also incorporates validation of the load calculations by
refrigeration software, selection criterion of suitable refrigerant and
selection/calculations related to major components of the system.
