Carrier has extended its water-cooled variable-speed screw chiller line, the AquaEdge 23XRV series, to offer a wide range for this product segment.
The AHR Expo placed an emphasis on energy efficient products by designating them with green labels in the booths. Product manufacturers, such as LG Electronics and Xylem, also used the expo to introduce their new and more energy efficient product lines for 2014.

The new addition to Star’s air cooled Indigochiller range uses the synthetic refrigerant R1234ze, which has a low Global Warming Potential of 6. This is a highly energy efficient, low noise chiller solution for building services, HVAC and process cooling.
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.
Featuring Individual Control of Multiple Room Units And Standard-equipped with High Value-added FunctionsTokyo, Nov 25, 2013 – (JCN Newswire) – On November 25 Mitsubishi Heavy Industries, Ltd. (MHI) will commence domestic marketing of a newly developed series of packaged air-conditioners, the “HYPER VSX Series,” equipped with the dual capability to control multiple room units simultaneously or individually.
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.
