The latest multi-zone split system from Fujitsu is the AOU45RLXFZ, five-zone heat pump. The heat pump system permits connection of between two and five indoor units to one outdoor condensing unit. The company says the system offers high efficiency operation of up to 19.7 SEER and 10.3 HSPF.
SEMCO® LLC has introduced the NEUTON™, a plug-and-play controlled chilled beam pump module (CCBPM) for reducing chilled beam system installation and operational costs. According to the company, NEUTON is the industry's first proactive condensation control device for active chilled beams. It is a factory-built and pre-tested CCBPM package complete with its own powered integrated DDC, chilled and hot water connections, valves, variable-speed electronically commutated (EC) motor pumps, smart sensors and other features.
Designed with 4-in flanged ports and only three moving parts, Tri-Rotor’s 200 Series pumps are heavy-duty, low-maintenance workhorses for pumping liquid and semi-solid materials with viscosities from 40/4 to 100,000/21625. Flow rates range from 58 to 240 gpm (200 gpm at 430 rpm). The 200 Series includes three head types: variable volume, relief valve, and transfer.
RectorSeal® has launched the MicroV ductless mini-split air-conditioner condensate pump, which the company says combines the quiet-running Silent+ technology along with a univolt power supply and plug-and-play power/communication connection cable.
The HSC Firepak™ from Armstrong features a compact design, which officials describe as a “plug and leave” design. The company also said it features readily available CAD drawings, specifications, dimensions, and pricing data.
Bosch Thermotechnology has launched its new LM Series water-to-water (W2W) heat pump line for new commercial and retrofit applications. The LM Series includes five models from 2 to 6 tons. They can be used in horizontal and vertical configurations depending on the application, and feature a two-speed scroll compressor and a commutated motor as standard components for efficiency and comfort. They achieve up to 32 EER part load and up to 22 EER full load.
Taco has expanded its suction diffuser line with three new sizes: 4- by 2.5-in, 5- by 3-in, and 8- by 5-in sizes. Taco says its suction diffusers incorporate numerous features into one device that simplifies installations and reduces installation costs.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
