HVAC SOFTWARE
The software available from HVAC Prime Source (HPS) is all based on Excel from MS Office, and also
compatible with OpenOffice that is available free on internet. Only basic knowledge of Excel is required,
and the instructions for using this software are very simple. A description of the software available from
HPS is provided below. This software is much simpler to use than the typical software available in the
HVAC industry, which is much more complicated and expensive. The HPS software is very low cost, and
along with each purchase several free software will be provided. The list below provides the price of each
software, and also the software that will be provided free with purchase. The software can be purchased
by using the "Add to Cart" button provided next to the software, and you will receive the software file to
download by email within 5 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, and it is essential for designing all
HVAC systems. The calculation method and data used is based on ASHRAE and Carrier Handbooks.
Cost = $ 18.00
- Free Software provided with this purchase -
- Cooling Load Formulas
- Pipe Insulation
- HVAC Unit conversions
- Description of the free software is given below.
2. Duct / Fan Pressure Drop
- 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, duct
fittings and air flows. This program provides a simplified calculation for determining the fan
differential pressure. The program also facilitates drawing a schematic flow diagram of the system.
The calculation method and data used is based on ASHRAE and Carrier Handbooks.
Cost = $ 18.00
- Free Software provided with this purchase -
- Fan Performance
- Air leakage
- HVAC Unit conversions
- Description of the free software is given below.
3. 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
and the most commonly used refrigerants R22, R134a, R407c & R410a. The calculation method and
data used is based on ASHRAE and Carrier Handbooks.
Cost = $ 18.00
- Free Software provided with this purchase -
- Pipe Insulation
- Refrigerant Data
- HVAC Unit conversions
- Description of the free software is given below.
- 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. 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
- Free Software provided with this purchase -
- Pump Performance
- Pipe Insulation
- HVAC Unit conversions
- Description of the free software is given below.
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. This software is provided free with
purchase of one of the software as indicated above.
- 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.
This software is provided free with purchase of one of the software as indicated above.
- 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. This software is
provided free with purchase of one of the software as indicated above.
- 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. This software is provided free with purchase of one of the software as indicated
above.
- 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. This software is provided free with purchase of
one of the software as indicated above.
- 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 quantity, and
several others. Normally these conversions are either not available in standard conversion tables or
require hand calculations. This software is provided free with purchase of one of the software as
indicated above.
11. Refrigerant Data (Free)
- This software provides the pressure temperature data for the most common refrigerants, and is
provided free with purchase of one of the software as indicated above. This data is very useful in
sizing refrigerant lines and trouble shooting air conditioning equipment problems. It provides a
wide range of pressure temperature data for the following refrigerants for quick reference.
CFC Refrigerant - R11, R12, R113, R114, R500
HCFC Refrigerants - R22, R123
HFC Refrigerants - R134a, R407c, R410a
This software is provided free with purchase of one of the software, as indicated above.
