Factors that a Heat Load Calculator Calculates to Provide Building Service Providers with the Most Suitable Air Conditioning System
Building engineers use an air conditioning load calculator to obtain information for proper equipment selection, system sizing, and system design. The data provided by the building service software allows them to evaluate the best options for load reduction. Building vendors can also obtain partial load analysis as needed for system design, operations, and control. The air conditioning load calculator also aids building contractors in sizing the appropriate air-conditioning system based on heat gain and/or losses in buildings. If it is cold outside, the building engineers can add in the heat loss from space, while removing the amount of heat gain if it is hot outside.
Heat gain or heat loss in a
building depends upon a variety of factors such as:
·
The temperature difference between outside
temperature and the desired temperature
·
The type of construction and the amount of
insulation in a building’s ceiling and walls
·
Shade on the building’s windows
·
Leaks into indoor space
·
The number of occupants in a building, and
·
Amount of lighting in the room
Other factors that an air
conditioning load calculator can take into account in order to provide you with
the desired size of the air conditioning system include sensible heat gain,
space cooling load, relative humidity, thermal resistance (R), latent heat
loads, and others. The building service software's careful analysis of these
factors will determine the efficiency, performance, durability, and cost of
your air conditioning unit.
Here, are some of the most
popular air conditioning load calculators by ACADS-BSG, the leading building
services provider company.
CAMEL
air conditioning load calculator
The air conditioning load
estimation and psychrometrics calculator computes the design heating and
cooling loads, as well as the associated psychrometrics, for building air
conditioning plants. Overhangs are accommodated by the building service
software, which includes drop panels and reveals on both windows and walls. It
computes air quantities for the chiller, AHU, zone, and room loads, as well as
room and zone heating loads, with and without coil reset, and room
temperatures.
Technical
details of CAMEL load estimation and psychrometrics calculator:
·
The air conditioning load calculator performs
an hourly cooling and load analysis, taking account of thermal storage, on a
design day in each month of the year.
·
Specific monthly 3 pm design and dry wet-bulb
temperatures are available in the CAMEL air conditioning load calculator for
over 600 locations in Australia and for many offshore locations.
·
The building service software carries out a
psychrometrics analysis for each AHU with the coil performance expressed as a
bypass factor, leaving coil temperature or nominated air quantity including
fixed bypass and dump back systems.
·
Precalculated U values and surface densities
for a wide range of standard wall and roof constructions are available in the
CAMEL computer program.
·
Summary results provided by CAMEL air
conditioning load calculator include tables of loads and air quantities, load
charts, tables of check figures, etc., that can be selected using a series of
check boxes, pull down lists, or user-defined templates.
KOALA
air conditioning load calculator
The KOALA air conditioning
load calculator is intended for use by designers and contractors responsible
for installing air conditioning units in small commercial and residential
buildings. It generates a detailed load chart outlining the input and design
data used to generate each individual component of the load.
Other
key features of the KOALA computer program
·
The air conditioning load calculator KOALA
can be used for analysing buildings in Northern or Southern hemispheres, and
the user can enter their own design conditions for locations not provided in
the computer program.
·
Graphics are provided on the windows and
external walls & roofs screens, to assist the user with checking their
input data.
·
Air quantities for each zone are determined
in the CAMEL air conditioning load calculator based on the leaving coil
temperature or bypass factor entered by the user.
·
Monthly critical or comfort, summer, and
winter design conditions for over 600 locations in Australia, and for many
locations in New Zealand, Papua New Guinea, and South East Asia are available
in KOALA computer program.
·
The results of KOALA air conditioning load
calculator, which is actually a simplified version of the CAMEL computer
program include a cooling and heating load chart for each zone. Summary results
and tables of these can be individually selected using check boxes to build up
a print file.
·
Templates are provided in KOALA building
service software for a number of preset results selections that can be compared
on the screen. Tables include the summary results for each zone and tables of
cooling loads and air quantities for each zone and for the sum of all zones.
