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.
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.
In fluid-based HVAC systems an impeller is a component of the pump that creates pressure to maintain flow. In this post we’ll touch on key design aspects of impellers and present answers to the most common questions.
Armstrong Fluid Technology has formed a strategic partnership with Hysopt to bring customers new insights into HVAC energy saving options, harnessing state-of-the-art digital twinning.
Bringing together Armstrong’s extensive experience of installations worldwide, and Hysopt’s powerful technology, the new partnership will provide customers with more robust scientific simulation and verification of HVAC system energy and carbon savings than ever before.
Stephen Hart, spokesperson forArmstrong Fluid Technologyexplained: “Reliable information on the potential for improving energy efficiency of HVAC systems has never been more crucial. World events have brought a new sense of urgency.
It’s important for HVAC system designers to understand that the relationship between pump costs and pump size is not a simple straight line. As pump sizes increase, the costs for the equipment, related components and installation increase faster. The result is that a pumping system that serves an HVAC load using two small pumps is less expensive than buying and installing one large pump.
As facility managers, contractors and service professionals gain experience working with remote performance tracking capabilities for intelligent pumps, the HVAC industry is learning how valuable this type of subscription service can be. It seems that many customers originally agreed to the purchase of a performance tracking subscription service on the assumption that it would serve only as a security blanket, but would be mostly unnecessary. Based on the testimonial stories provided by customers describing service, maintenance and performance management scenarios, the subscription service has proven its value many times over. Examples detailing how remote performance tracking prevented a serious negative outcome, organized into categories, are presented below.

Energy plays a crucial role in our daily lives and in the economy. Energy is not only a basic human need, but also a strong indicator of social and economic development.
As our world becomes more urbanized, global demand for energy is increasing rapidly, with expected growth of 55% over the next ten years. With this growth comes increasing concern about energy security, economic competitiveness and of course, environmental impact.
The Hydronics Industry Alliance released a report studying a VRF system and hydronic system installed in the same building. The report found the VRF system had higher energy consumption in three consecutive years of operation.
With a considerable volume of contradictory information in circulation regarding the application of different technologies for HVAC systems, this article seeks to explain some of the technical aspects of variable refrigerant flow (VRF) systems, and offer comparisons on the basis of cost and performance to more standard hydronic systems. While some of the material presented here are drawn from industry literature, the majority is drawn from peer-reviewed studies conducted by recognized industry professionals.
Working remotely, new safety protocols, and how remote monitoring can help HVAC system users.
As we work through complex and trying circumstances, with large portions of the population self-isolating and dependent on building mechanical systems for safety and comfort, the world of heating, ventilation and air conditioning (HVAC) has seen numerous instances of people extending themselves, beyond the ordinary, in the service of others.
