/ I A Q Samsung Wind-Free Residential Heat Pump Features 2-Step Cooling System Samsung's Wind-Free wall-mounted air conditioner provides customers with a cooler indoor climate and optimal energy efficiency without the discomfort of direct cold airflow. The AR9500M provides customers with the ideal condition by maintaining the desired room temperature, using Wind-Free Cooling to gently disperse cold air through 21,000 micro air holes. A two-step cooling system, which first lowers temperatures in fast cooling mode, automatically switches to Wind-Free Cooling mode creating still air once the desired temperature is reached. The unit is also Wi-Fi enabled so it can be controlled from anywhere through Samsung's Smart Home App. CHECK OR CIRCLE #129 Closed Circuit Cooler Off ers Greater Capacity, Smaller Footprint New from Evapco is the eco-LSWE closed circuit cooler with an ellipti-fin coil and CrossCool internally enhanced tubes to increase the heat transfer of the coil — improving the unit's cooling capacity. The cooler offers greater capacity in a smaller footprint than the traditional bare-tube, forced draft cooler — making it ideal for replacement jobs where additional capacity is needed within tight space constraints. The eco-LSWE also offers reduced unit height and total connected horsepower, while saving water through significantly increased dry bulb switchover temperatures. The spirally finned elliptical tubes increase both wet and dry capacity, and are the ideal solution for indoor applications, confined layouts, low sound requirements and direct replacements. CHECK OR CIRCLE #128 hvac/ products /IAQ IWAVE-R ACTIVELY TREATS AIR IN RESIDENTIAL HVAC SYSTEMS Nu-Calgon has launched the first self-cleaning ionization air purifier designed for residential HVAC systems. Called the iWave-R, the no- maintenance air purifier actively treats the air as it passes through a home's HVAC system without creating ozone or other harmful byproducts. The iWave-R is a bi-polar, high-output ion generator designed specifically for treating air in residential duct systems up to six tons in size. As the air flows past the iWave-R, positive and negative ions actively purify the air, killing mold, bacteria and viruses in the coil and living space. The ionization process also reduces allergens, smoke and static electricity, as well as controls odors (cooking, pet, VOCs) and other particles in the air. CHECK OR CIRCLE #132 DATALOGGERS OPTIMIZED FOR IAQ PROCESS CONTROL DIAGNOSTICS Extech Instruments recently introduced its new SD900 and SD910 3-channel DC current and DC voltage dataloggers. The new data recording instruments are optimized for extended monitoring of milliamp (SD900) and millivolt (SD910) signals throughout a commercial, industrial or residen- tial facility. The instruments help HVAC/R and indoor air quality technicians, as well engineers, to validate efficient system operation and iden- tify trends that can impact uptime, air quality or system efficiency. Use the new dataloggers throughout a site to monitor diverse process systems regulated or monitored using milliamp (e.g., 4-20mA) or millivolt signals (e.g., controls, controller electronics, indicators). Extended monitoring can help reveal problems in complex HVAC environments. CHECK OR CIRCLE #130 NEW SENSOR HELPS BUILDING OWNERS, CONSUMERS MONITOR AIR QUALITY Honeywell's HPM series particle sensor is de- signed to work in HVAC systems and consumer products such as air purifiers to measure air quality in homes, buildings and public spaces. The new sensor uses laser technology to ac- curately and cost effectively monitor for fine inhalable particles that are 2.5 micrometers in diameter or smaller. For reference, the aver- age human hair is nearly 30 times larger at 70 micrometers in diameter. The sensor outputs an electrical signal that can be fed into HVAC control systems in buildings and homes or into other air monitoring devices. This information can alert building operators that air purification systems should be activated or if outdoor air could be used to improve indoor air quality, or when an air filter needs to be changed or early maintenance should be performed on indoor air delivery systems.
