optimum performanceany given time

rmstrong Design Envelope pumps are a complete solution for heating, cooling and plumbing systems. The integration of a perfectly matched pump, motor and intelligent variable speed controller creates the highest value pumping solution.

Whether driven by social, environmental or fiscal responsibility, forward-thinking organizations must embrace energy-saving technologies and practices.

Through design advances, Armstrong has eliminated the cost trade-offs that are frequently attached to sustainable choices. Design Envelope offers the lowest installed cost and the lowest life cost of any pumping solution today.

5.25 6.50

Design Envelope solutions reduce pumping costs through variable speed, demand-based operation — consuming only the energy required, based on current system demand.

Design Envelope pumps use a combination of optimized impeller size and speed control for energy efficient operation within a given performance

envelope. The performance envelopes are selected for the best pump efficiency where variable flow systems operate most often. This ensures a building’s pumping system consumes as little energy as possible. It also ensures that the installation meets or exceeds ashrae 90.1 guidelines requiring 70% energy savings at 50% of peak load.

Most systems operate at less than 60% capacity 90% of the time or more.

Traditional pumps are designed for high efficiency operation at full load.

controls

In a chilled water system, a building’s temperature controls influence the local flow of control valves that modulate

the flow to the cooling coils (load). As the control valves open for more chilled water flow, the differential pressure across the valve decreases.

The controller reacts to this change by increasing the pump speed. If the control valves close to reduce the chilled water flow, the differential pressure across the valve increases and the controller reduces the pump speed.

Equipped with Sensorless tech-nology, Design Envelope solutions do not require an external sensor to monitor and control the hvac load.

how it works

Equipped with Sensorless technology, a Design Envelope pump’s performance characteristic curve (power draw and

rpm) and operating curve are pre-programmed into the controller. During operation, the controller monitors the power and speed of the pump and establishes the hydraulic performance and position

of the pump’s head-flow condition relative to the system requirements. As the building’s control valves open or close to regulate flow to the cooling coils and maintain building occupant comfort, the Sensorless controller automatically adjusts the pump speed to match the required system pressure and flow.

Fewer connecting components

Managed redundancy without duty/standby

Most multi-pump control systems stage pumps on the basis of capacity. The pspc control logic draws on detailed mapping of pump efficiency

curves to determine the best possible combination of pumps and operating speeds for any flow requirement.

When the pspc calculates that a pump array would operate more efficiently with one more pump added to the current set of operating pumps, the control logic turns on one more pump and coordinates the operating speeds of all the operating pumps to share the load.

Parallel Sensorless Pump Control (pspc) is a technology

that minimizes the energy costs of multi-pump installations

using best efficiency staging.
