Daikin
Daikin AC introduces the Round Flow cassette fan coil units (model FXFQ-PVE) designed to provide 360 degree air flow, and reduce drafts, temperature fluctuations and air velocity. The 3x3-ft. fan coil units can be combined with Daikin's VRVIII-S, VRVIII, and VRV-WIII. The unit will be available in seven different capacity sizes ranging from 9,000 to 48,000 BTUH and incorporates many features unique to Daikin, sources say.
The design of the Round Flow ceiling cassette features a new drain pan structure and discharge grill style, resulting in effective and uniformed 360 degree air distribution into the space. The unit features a hollow, serrated design turbo fan combined with a new high efficiency fan motor to improve performance and reduce sound levels to as low as 27 dBA.

LG
LG's Multi-V VRF technology uses both inverter and constant speed compressors in tandem to provide an efficient means of meeting a customer's heating and air conditioning needs. This technology further reduces operational noise for a better guest experience. Hoteliers will appreciate that it limits energy expenses and uses the industry-standard refrigerant R-410A, sources claim.
The advanced VRF heat pump system in LG's Multi-V Mini uses sophisticated inverter technology and zoned evaporators that promote better dehumidification and tighter temperature control while avoiding unnecessary energy consumption in unoccupied rooms. Hoteliers can use this technology to control which rooms operate to avoid energy usage.
Enhancing the durability of the Multi-V system, this model comes with LG's Gold Fin Anti-corrosion coil protection. This means that the outdoor coil surface is covered and protected from the corrosive effects of outside air, thereby extending the operational life of the unit.

McQuay
McQuay announces its premier line of Maverick II commercial rooftop systems. The new optimized Maverick II rooftop system provides building owners with unmatched room temperature control and comfort through the use of modulating hot gas reheat and precise controls. The new functionality includes integrated compressor and reheat control that automatically energizes the reheat whenever dehumidification is needed, without using additional energy. The modulated hot gas reheat control feature reduces fluctuations in air temperature and humidity levels, helping to ensure a consistently comfortable environment, which makes it ideal for use in healthcare facilities, schools, hotels and office buildings, company sources say. By using micro-channel coils in the reheat design, more Btu per square foot of coil is achieved and less refrigerant charge is used, which minimizes maintenance and omits the need for receivers.

Trane
The Trane model CGAM air-cooled scroll chiller now offers a factory-installed evaporator pump package designed to save time at installation and commissioning. The system’s energy efficiency and low noise make it ideal for the K-12 educational environment. It can also be used effectively in commercial real estate, healthcare and other markets, company sources say.
Featuring a dual pump setup for built-in redundancy – offering lead/lag and failure/recovery capability – this pump package is controlled via an inverter. The inverter is adjusted upon startup to balance the system flow and head requirements. This saves on wasted pump energy caused by a traditional balancing valve.

Daikin
The Daikin Altherma is an innovative alternative heating and domestic hot water solution. The air-to-water heat pump system maximizes comfort and energy savings by capitalizing on Daikin’s technological strengths. The Altherma consists of two main components (outdoor unit and hydrobox) combined with optional accessories such as a water tank and solar thermal kit. For space heating, the unit can be connected to low temperature radiators, under floor heating or fan coil units. The Daikin Altherma uses R-410A refrigerant.
Through its thermodynamic cycle, the heat pump "pumps" heat from the outside air even at a temperature as low as -4F and uses it through a water distribution system in the home. Daikin Altherma is offered in two versions: a split type system where the hydrobox is installed inside the house connected through refrigerant piping to the outdoor unit, and a monobloc type system, where the hydrobox resides in the outdoor unit, eliminating the need for refrigerant piping connection.

Lennox
The SunSource® Home Energy System harnesses solar energy to power the heat pump or air conditioner, or other home electronics and appliances when the heat pump or air conditioner isn’t being used. If the system generates more solar power than is needed, the excess power is sent back to the utility company, possibly entitling your customers to a utility bill credit.
The Dave Lennox Signature® Collection XC/XP21 or XC/XP17 heat pumps and air conditioners come "solar ready," meaning customers can choose to include solar panels at installation or wait until later. Up to 15 of the weather- and impact-resistant panels can be added per outdoor unit whenever your customers choose.

Rheem
Rheem recently introduced its new Integrated Heating & Water Heating System Powered by Tankless Technology, a product that offers home heating and hot water from a single source. When combined with Rheem cooling equipment, the system offers complete air and water home comfort. According to company sources, the Rheem heating & water heating system is the first of its kind to be designed, built, and warranted by a single manufacturer. The heart of the Integrated Heating & Water Heating System is Rheem tankless technology, which in this new application not only fulfills hot water needs, but also provides heating to the entire home. When a Rheem tankless water heater is matched with a Rheem hydronic air handler, hot water is circulated through the hydronic air handler to provide warmth, and is then re-circulated back to the tankless water heater to ensure that no water is wasted. According to company sources, the combination makes the entire system up to 94% efficient.

Trane
The Trane EarthWise™ hybrid system combines an XLi electric heat pump with a variable speed gas or oil furnace for ultimate efficiency. With the flexibility of two fuels, the system can actually optimize energy use by switching back and forth to whichever source is most efficient for comfort. Even in northern climates, the electric heat pump can find enough ambient heat in the air to keep a home warm and comfortable well into fall, sources say. But when there's not enough ambient heat and a fossil fuel becomes the most efficient option, the system will switch to either natural gas or heating oil for the heat of a furnace. When winter ends and warm temperatures return, the heat pump will reverse its operation; instead of finding ambient heat in the air, it will pull the heat out of the home and radiate it outside. The furnace won't ignite, but will instead serve as a variable-speed blower to move the cooled air produced by the heat pump.
