Petra’s Role in Ozone Protection

Air Conditioning, Heat Pump and Refrigeration systems affect the environment and the ozone layer through the release of refrigerants into the atmosphere and also through the release of carbon dioxide when generating the power for operating the system through its life time.

To reduce the impact of HVAC Systems on the Environment; Petra has replaced ozone-depleting hydro-chlorofluorocarbons HCFCs (R-22) by Hydrofluorocarbons (HFCs) (R-410A, R-407C and R134a Refrigerants, Ozone Friendly), Petra produces highly efficient products to reduce the electrical energy consumption for its units, thus helping to protect the environment

Energy Saving Solutions

Energy efficiency requirements are becoming more rigorous with the growing concerns for environmental and economic sustainability. Around 70 percent of energy usage and 63 percent of greenhouse gas emissions are estimated to be contributable to heating, cooling and ventilation. HVAC typically accounts for 40-50 percent of the total energy bill for businesses and commercial buildings. Properly selected energy efficient HVAC equipment can significantly reduce energy costs and meet environmental standards.

Petra Engineering Industries provides a wide range of solutions that incorporate the latest technologies that facilitate energy saving requirements and enhance indoor air quality and occupant comfort requirements.

Highly-Insulated Air Handling Units

Petra’s AHUs thermal resistance is increased by using high resistive insulation material, closed-cell foam insulation, with a lower thermal conductivity with 2” – standard thickness and, -4”optional:

As the Ultimate solution for higher insulation, Petra’s new design of Thermal Break Units for AHUs, increases the thermal resistivity. There is no contact between inner and outer surfaces, reducing thermal conduction.

Variable Water Volume (VWV)

Petra’s variable water volume systems deliver superior indoor comfort, energy efficiency,design flexibility and ease of installation.

The system is integrated under a powerful control platform that manages the HVAC system and optimizes operating system efficiency.

(VWV) Technical Features:

1. 25%less power consumption in comparison to equivalent capacity DX systems.
2. Contributes to earning LEED points in energy and atmosphere credit according to the requirements of the performance rating method in ANSI/ASHRAE/IESNA standard 90.1 – 2010.
3. VWV may be suitably designed to provide 100% fresh air to occupant spaces.
4. Efficient in high rise buildings, no height limitations.
5. Flexibility in installation with no limitation on the distance between the indoor and outdoor units.
6. Modulating load down to 1% without any issues of oil recovery.
7. Easy to detect and maintain leakages.
8. Suitable for fully and partially occupied buildings.
9. Factory mounted and factory commissioned controls that significantly reduce time required for onsite commissioning.
10. Petra’s VWV system contributes to fulfilling the prerequisites and earning points for.
