Many decisions are made during the design of a chilled water plant that have long-lasting impacts on the facility’s energy use and demand. Additionally, consistent operations, benchmarking, and submetering can help perpetuate savings throughout a building’s life cycle.
Greenheck has added two new models to its line of high-volume low-speed (HVLS) fans. Model DS-3, a three-blade HVLS fan for large commercial and industrial spaces, offers capacities up to 164,900 cfm and is available in 14- to 24-foot sizes. Model DC-5, a five-blade HVLS fan featuring a lightweight design to complement office spaces, restaurants and more, offers capacities up to 54,900 cfm and is available in 8 -to 14-foot sizes.
A. O. Smith launch of its Commercial Heat Pump Water Heater (CHP-120) for light commercial applications such as restaurants, schools, retail buildings or any facility which would traditionally use a standard commercial electric water heater.
EVAPCO has introduced the newest addition to its ESW closed-circuit evaporative cooler line, the single cell, 14-by-22-foot “Big Box” ESW4 — now with up to 40% higher capacity than the 12-by-18-foot ESWB. The ESW4 is offered in more than 130 models with capacities between 270-670 nominal tons, and with fan motor sizes of 20-100 hp.
Greenheck says it has expanded its line of Dedicated Outdoor Air Systems (DOAS) for high percentage and 100 percent outside air. Pre-engineered rooftop ventilator models RV-110 and RVE-180 with energy recovery offer capacities up to 18,000 cfm, up to 70 tons of packaged cooling, and 1,200 mbh indirect gas-fired heating.
Armstrong Fluid Technology has developed ADEPT Select, a new online selection software for engineers and contractors who need to size and select Armstrong solutions. ADEPT Select includes the broad range of Armstrong solutions and services and is compatible with hand held devices.
Friedrich is now offering its VRP® (Variable Refrigerant Packaged) Heat Pump system in a larger three-ton size. Originally available in one or two-ton capacities typically used for lodging and hospitality properties, Friedrich is debuting the larger capacity VRP as a solution for multi-family and other light-commercial applications.
Cooper&Hunter added a new series to its current heat pump line-up with single-zone applications. The new Dakota series aims to ensure consistent warm comfort during extreme climate and the condenser heat output capacity allows the unit to work efficiently as a primary heat source even if the temperature drops to a sub-zero level of minus 22ºF.
Danfoss says it has engineered a solution that safely controls hot gas injection with the ICSH Dual Position Solenoid Valve. Complying with the latest IIAR safety recommendations for soft gas applications, the ICSH Dual Position Solenoid Valve provides a gradual, time-controlled opening for a smooth pressure build-up in the evaporator before it opens the flow to 100% for full defrost.
On Demand In this segment of our webinar series, we will examine the issues of fuel autonomy, storage capacity, and other related topics to consider when specifying, selecting, and installing an emergency backup power system.
Engineered Systems magazine’s April 2020 issue examines the latest comfort mystery at the Watergate Office Building, the codes and loads that must be considered when specifying temporary HVAC systems, why designers and facility managers shouldn’t fall trap to capitalistic pitfalls, and more.
