Pneumatic Thermostat

Test for reducing air thermostat confirmed Game-Changing wireless costs, time and facilities disturbance renovate existing buildings for Connectivity Smart Grid.

Envirosystems Cypress, a subsidiary of Cypress Semiconductor Corp. / quotes/comstock/15 *! CY / quotes / nls / CY (CY 11.08, -0.49, -4.24%) announced today that the California Smart Grid Center (SCSC), has passed the test demonstration of the thermostat Cypress Envirosystems "without pneumatic thread (WPT) solutions. The SCSC is funded by the California Energy Commission and the ground to prove impartial Smart Grid technologies in California.

The test confirmed the significant reduction of the WPT in cost, time and disruption to the renovation of existing buildings, and thus enable them to Smart Grid connectivity Auto-reply to the request. The patent-pending hybrid technology and digital tire used by the WPT opens the possibility for millions of older buildings to help reduce the peak load and energy efficiency strategies that were previously impractical due Recovery of investment and long disruption to building occupants.

Approximately 6,000 square feet of office space at Sacramento State University has been selected for the demonstration test. Before the renovations, the offices used non-contact pneumatic thermostats to control heating and cooling. These thermostats are not inherited able to control the temperature to distance and could not interface with the intelligent network for auto-response to the request. adapting them to modern communication digital thermostats using conventional technology would have been extremely expensive, with a payback period of five years or more. It would also be necessary to open walls and ceilings, with significant disruption to building occupants.

For the demonstration test, the SCSC used tires innovative wireless thermostat system, which costs about 80% less than conventional technology. The facility at Sacramento State University was completed in about two hours during working hours, with virtually no disruption to the occupants. If the conventional technology were used, it would have taken several days and needed cleaning asbestos and other hazardous materials exposed at work.

Once installed, the thermostat activated the remote control and reference tracking area, temperature and pressure from industry (heating or cooling demand) through an operator position. The system can also interface with existing automation systems using BACnet and provides an integrated interface protocol compatible OpenADR developed by the U.S. Department of Energy Lawrence Berkeley Laboratory, which allows communication with the public services self-response to the request. This interface allows buildings automatically reduce power consumption during periods of high demand (by increasing the temperature setting of thermostats, for example).

"For the Smart Grid to achieve its full potential, we need intelligent building to talk to him. Development of low cost and non-disruptive way to make existing buildings "smart" is a very important issue to address, "said Emir Jose Macari, Dean of the Faculty of Engineering and founding director of Central California in Sacramento Smart Grid State. "The Cypress Envirosystems WPT system was installed in record time and has performed flawlessly for three months of the demonstration test. I am impressed by the performance of the system, but mainly because of non-invasive devices and installation. "

Similar large-scale projects using WPT, involving more than one million square feet, each confirmed WPT can provide up to 1kW of peak load, and reduced to 15-30% of consumption HVAC energy. The low installed cost allows very attractive payback periods of 18 months or less. To further reduce the initial cost, the WPT is also eligible for incentives of public services.
