Our most recent video is an explanation of how flow levels inform HVAC optimization.

 

Many of today’s buildings rely on HVAC systems that were oversized on installation to address uncertainty in cooling and heating loads. Unfortunately, many building occupants still experience discomfort, even with the extra capacity in HVAC systems. To make matters worse, most HVAC systems operate inefficiently and this poor performance goes unnoticed by building owners and operators. Without automated maintenance alerts, and regular recommissioning, most buildings will experience a drift in HVAC performance efficiency of 10-30% in just 2 years.

Design Envelope technology is an intelligent, connected solution that tracks actual system conditions, and dynamically adjusts equipment operation. Pump Manager, a cloud-based service that leverages the intelligence of Design Envelope pumps, allows operators and managers to actively manage the performance of an HVAC system.

Background

Sarrebourg (pop. 13K) is a town in the administrative region of Grand Est 350 km northeast of Paris.

To reduce the territory's dependence on fossil fuels, municipal leaders agreed to fund a hot-water district heating system using wood heating to provide heat and domestic hot water. The system design would eventually grow to include 32 delivery stations and an 8km network of piping. The decision represented a total investment of 12 million Euros.

CAD (computer-aided design) drawings are digital files that house 3D & 2D models of physical objects. CAD files can include information such as geometric data, manufacturing data, material properties, and other data. CAD files are ‘to-scale’, meaning designers are able to create drawings in real-world dimensions.

A Review of Pump Types for HVAC Systems

Pumps can be grouped according to the method of displacement, the direction of fluid flow, orientation, and control capabilities. Major types of pumps include positive-displacement pumps, centrifugal pumps, and axial flow pumps.

Delta Hotels Toronto is one of the largest, most luxurious hotels in Canada and is rated as one of the most sustainable. Delta commissioned an upgrade of one of their existing pumps to a new Design Envelope Tango. Energy savings post-installation have proven that the Tango pump was the right choice.

After a major refurbishment to guest suites and event spaces, managers at the Park Hyatt hotel wanted to improve heating efficiency and reduce energy use. Armstrong recommended replacing 1 of 2 existing pumps
with a Design Envelope DEPM pump, to provide a head-to-head efficiency comparison.

A domestic water pressure booster system is essential for buildings with inadequate supply pressure from the city or buildings served from storage tanks. A booster ensures potable water is available at appropriate pressures on every level of a building. Because flow demand in most buildings is highly variable, variable frequency drives and automatic controls are an excellent option to reduce the energy used to maintain constant pressure.
