HVAC Software
The software available from HVAC Prime Source (HPS) is all Excel based. Only basic knowledge of Excel is
required, and the instructions for using all the software are very simple.
A description of the software available from HPS is provided below. Some of this
software is free, while others are available at a very low price. Free software
can be downloaded by using the links below, while low price software can be
purchased by using the "Add to Cart" buttons and you will receive it
within 5 to 10 days.
NOTE: In case the software has sample values in the input cells,
simply over-write with the new values.
- 1. Cooling and Heating Load
This
software provides the cooling and heating loads for sizing the HVAC system
and determining air flow quantities. The input required is environmental and
room temperature conditions, room dimensions, construction details, and
equipment/lighting heat loads. This program provides a simplified
calculation for estimating the cooling & heating loads for most systems. It
is a far simpler tool to use than the typical software available in the
industry, which are more complicated and expensive. The calculation method
and data used is based on ASHRAE and Carrier Handbooks.
Cost = $ 18.00
This software
provides the pressure drop for various duct fittings to be able to determine
the total pressure drop for a typical system and size the fan. The input
required is duct dimensions, fittings and air flows. This program provides a
simplified calculation for determining the fan differential pressure. It is
a far simpler tool to use than the typical software available in the
industry, which are much more complicated and expensive. The calculation
method and data used is based on ASHRAE and Carrier Handbooks. The program
also facilitates drawing a schematic flow diagram of the system.
Cost = $ 18.00
- 3. Pump Pressure Drop
This software
provides the pressure drop for various pipe fittings to be able to determine
the total pressure drop for a typical chilled water or hot water system and
size the pump. The input required is pipe dimensions, fittings and flow
gpm. This program provides a simplified calculation for determining
the pump pressure head. It is a far simpler tool to use than the typical
software available in the industry, which are much more complicated and
expensive. The calculation method and data used is based on Crane, Cameron
and Carrier Handbooks. The program also facilitates drawing a schematic flow
diagram of the system.
Cost = $ 18.00
- 4. Refrigerant Pipe Sizing
This software
provides the sizing of the refrigerant pipes/lines for a typical split
air-conditioning or refrigeration system, which has the compressor/condenser
unit located separately from the cooling coil. It is very critical to size
the refrigerant lines correctly, or it can result in system malfunction or
compressor damage. This software sizes the refrigerant compressor suction,
discharge and liquid lines, and provides the recommended sub-cooling and
superheat temperatures. The input required is max/min cooling load, length
of piping and fittings, condensing temperature, etc. This program provides a
simplified calculation for determining the line sizes for typical copper
tubing material. It is a far simpler tool to use than the typical software
available in the industry, which are more complicated and expensive. The
calculation method and data used is based on ASHRAE and Carrier Handbooks.
Cost = $ 18.00
- 5. Cooling Load Formulas (Free)
This software provides calculations to determine the sensible, latent and total cooling loads,
by using formulas based on
air flow parameters. The inputs required are air flow rate, temperature, and
moisture/ humidity, which are available from the design conditions and
Psychometric charts. These formulas can be used to determine the outside
makeup air load based on outside air and room air parameters, and total load
on the cooling coil based on coil inlet and outlet air parameters. This program provides a simplified
calculation for determining the sensible and latent cooling loads essential
for sizing and specifying the equipment.
The calculation method is based on standard formulas given in ASHRAE and Carrier Handbooks.

- 6. Fan Performance (Free)
For a given airflow and pressure, this software provides the fan
Horsepower, Amps current, and fan heat gain or increase in supply air
temperature due to fan heat. It is a useful tool to
estimate the power requirements and the heat load from the fan that needs to
be added to the cooling load. Click on the link below to download this
software.
Fans Performance
(version 1).xls
- 7. Pump Performance (Free)
For a given fluid flow and pressure, this software provides the pump
horsepower, and NPSH. It is a useful tool to estimate the power requirements
and the NPSH for a Pump. Click on the link below to download this software.
Pumps Performance
(version 1).xls
This software determines the air leakage through the cracks or a
penetrations. It is a useful tool to determine the makeup air required for
room pressurization such as for clean rooms. It can also be used for air
leakages from ductwork, or in-leakage/infiltration of outside air to
determine the impact on heating or cooling load. The calculation method is
based on sharp edge orifice flows per Crane Handbook. Click on the link
below to download this software.

- 9. Pipe Insulation (Free)
This software provides the heat load from insulated or bare pipes, and
the insulation thickness needed for a given type of insulation to limit the
heat load and surface temperature, as required. The input required is pipe
dimensions, insulation k value, and temperature conditions. The calculation
method is based on ASHRAE Handbook. Click on the link below to download this
software.

1).xls
- 10. HVAC Unit Conversions (Free)
This is a useful tool to convert the units typically used in HVAC design,
such as inches of water gauge, velocity to velocity pressure, actual air flow
quantity to
standard air flow quatity, and several others. Normally these conversions are either not
available in standard conversion tables or require hand calculations. Click
on the link below to download this software.

Note: For the software that is not free, sales tax is required only for Illinois residents. Above costs
do not include any sales tax. | |
