New Products: HVAC Tools of the Trade


Humidity/temperature sensors for all standard HVAC applications offer an expanded signal range of 0 to 10 volts, 4 to 20 mA, and RTD and NTC outputs in 3-5% or 2% accuracy. Cover options include plain, or LCD display with temperature set point and occupancy override. An embedded microprocessor converts the sensor’s digital signal to a continuous 0- to 10-volt DC signal, which corresponds to 0-100% relative humidity. The humidity element is also conditioned and linearized from 0-95% of the range. For more information about the Q-Series from Siemens Building Technologies, click here .

ASHRAE Pocket Guide has information on refrigerants, ventilation rates, thermal comfort and acoustical data is highlighted and serves as a ready reference for engineers whose mobility keeps them from easy access to the ASHRAE Handbook volumes and information in ASHRAE standards. The 2005 guide features new information on performance and pipe sizing for new refrigerants, refrigeration safety, ventilation requirements for residential and non-residential occupancies, occupant thermal comfort, sound and vibration control, thermal storage, and radiant panel heating and cooling and air-to-air recovery.

Boiler Control Systems Engineering is a reference for those who work with boiler control systems. The text deals primarily with water tube boilers with induced draft (ID) and forced draft (FD) fans or boilers. However, the material can apply to any steam generator requiring the firing of fuel. The book addresses issues to be considered when defining measurement transmitters and specification for transmitters. Characteristics and sizing of final control elements are reviewed.

Hot gas reheat with direct digital controls has been added to the manufacturer’s line of rooftop units, including 12.5-, 15- and 20-ton models. The hot gas reheat feature uses native energy from rooftop units to provide comfortable space temperatures while reducing relative humidity levels. It complies with the ASHRAE 90.1 guidelines that limit the amount of new energy allowable for dehumidification using reheat. For more information about Voyager II from Trane, click here .
