HVAC System Using Membrane Technology to Be Launched

The system was developed in partnership with Saskatoon-based Venmar CES Inc. and the University of Saskatchewan mechanical engineering research group.

It uses a liquid-to-air membrane energy exchanger (LAMEE), which uses membranes to effectively recover moisture and heat energy before it is wasted in the building’s exhaust air.

10 Steps to Creating a Successful Sequence of HVAC Operation

The sequence of operation is one of the most important design aspects of any HVAC system. Without a proper sequence, the system is left to operate wildly—or not at all. When approached methodically, the process can be broken into smaller segments. We’ll look at the steps required to create a successful sequence of operation using a single-zone variable air volume (VAV) air handling unit serving a convention space. These same steps can be applied to any piece of equipment.

New Commercial HVAC Rooftop Units Offering Significant Energy and Dollar Savings

New super-efficient rooftop units that heat and cool commercial buildings offer significant energy and dollar savings, say scientists at the Department of Energy’s Pacific Northwest National Laboratory. They found that the devices reduce energy costs an average of about 41 percent compared to units in operation today.

The Benefits of Advanced Thermostats

Advanced thermostats communicate to the Internet, enabling visibility and control of HVAC systems via the web. Communication capabilities create opportunities for energy and demand savings through smarter controls and enhanced HVAC performance management by maintenance staff. Additionally, the advanced thermostats can integrate with and control other energy consuming systems, such as lighting.
