Johnson Controls has expanded its YORK line of YLAA Air-Cooled Scroll Chillers up to 200 tons. The company says the extended capacity of the YLAA offers a more cost competitive solution to 200-ton opportunities without sacrificing size, quality, and efficiency.
It might seem like an odd objective, but the potential efficiency gains are real. And from heat recovery chillers to modified humidification targets so are the opportunities to replace steam production with hot water generation and to manage remaining steam needs more intelligently.
The production of thermal power is critically important in carrying out the mission of health care facilities where it is used for space heating, humidification, domestic water heating, and for processes in dietary, laundry, and sterilization departments. The age of the hospital, the programs offered, and the regional climate will all affect the demand for thermal power.
Technical Systems (TSI), a division of RAE Corporation, has announced the availability of its Series 35 Evaporative Cooled Chillers. The company says the chillers have been specifically designed to provide-highly efficient cooling for commercial and industrial-duty applications.
Schaffner EMC introduced the ECOsine® Active 200/250/300A, a harmonic filter providing harmonic compensation in real-time for industrial and commercial environments. With a capacity of 300A, operating at 480VAC (+/- 10%), the connection-ready 200/250/300A (three-wire) cabinet models include forced air cooling and internal liquid cooling for the power electronics. The company said filters are capable of supporting large production facilities.
Sensaphone® will introduce its Sentinel™ PRO remote monitoring system, an enhanced version of the Sentinel cloud-based system that provides 24/7 remote monitoring of unattended HVAC units, freezers, refrigerators, boilers, and chillers. The Sentinel PRO system supports the Modbus communications protocol and includes a second relay output — capabilities required to monitor and control complex networks.
Daikin Applied has expanded its line of air cooled scroll chillers. The chillers are designed to help facility managers in K-12 schools better manage rising energy costs and the burdens of aging equipment. Trailblazer, the customizable chiller, is now available in sizes from 30 to 240 tons.
Johnson Controls has introduced the Quantech Air-Cooled Chillers. The company says the chillers offer up to 50% annual energy cost savings compared with the replaced chillers, have a low lifecycle cost, meet or exceed ASHRAE standards, and help earn LEED credit with a low refrigerant charge. Three models make up the Quantech chiller line. The QTC2 (15-50 tons) provides chilled water for all air conditioning applications using central station air handling or terminal units. The state-of-the-art installation uses tube and fin condensers, brazed plate evaporators, and scroll compressors.
Many engineers tend to avoid or delegate the nitty gritty of a ground source heat pump system, from soil moisture effects to building system (im) balance. It's time for designers to get in the loop.
