Integrates heat-pump and gas furnace systems to reduce fossil fuel usage

Mitsubishi Electric Trane HVAC US LLC (METUS), a leading supplier of Ductless and Ducted Mini-split and Variable Refrigerant Flow (VRF) heat-pump and air-conditioning systems, announces the introduction of the intelli-HEAT™ Dual Fuel System. This new Mitsubishi Electric solution is compatible with any thermostatically controlled furnace[1] and works with both single-zone and multi-zone systems. intelli-HEAT empowers homeowners who own gas furnaces to improve their homes’ comfort and sustainability by using an energy-efficient, all-electric heat pump as their primary heating source. The furnace remains available to the homeowner as a heating source for extreme cold conditions.

intelli-HEAT™ integrates a Mitsubishi Electric heat-pump system with an existing or new gas furnace to provide consistent, reliable heat in extremely cold temperatures. The need to use the existing gas furnace is dramatically reduced, diminishing a home’s reliance on fossil fuels.

intelli-HEAT offers homeowners the benefit of consistent year-round comfort thanks to its INVERTER-driven compressor technology. Homes with an existing furnace¹, with or without an existing air-conditioning system, can use the intelli-HEAT system for cooling during warmer months. The all-electric heating is operational while outdoor temperatures are as low as -13º F using the system’s Hyper-Heating INVERTER^® (H2i^®) technology.

During periods of extreme cold, intelli-HEAT may switch to the gas furnace as needed based on capacity threshold and economic balance points. The intelligent switchover function built into the control box of the intelli-HEAT system coordinates operation of the furnace and the Mitsubishi Electric heat pump. This smart heating management is designed to result in lower gas usage and reduced greenhouse gas emissions while providing homeowner comfort.

intelli-HEAT™ (installed atop a furnace) works seamlessly with existing furnaces.

“Because an intelli-HEAT system burns no gas, and generally requires less energy to heat a home than a typical gas furnace, homeowners using our new dual fuel system can reduce their greenhouse gas emissions, compared to using a gas furnace alone as the primary source of heating,” says Chris North, senior specialist, product marketing, Mitsubishi Electric Trane HVAC US LLC. “intelli-HEAT is a flexible solution suitable for homeowners replacing an aging air-conditioning system, adding to an existing furnace with no air conditioning, or for new construction.”

intelli-HEAT connects to a Mitsubishi Electric single- or multi-zone outdoor heat-pump unit and is available in 18, 24, 30, 36 and 42 KBTU/H capacities. Hyper-Heating INVERTER (H2i) systems are compatible and available for both single- and multi-zone applications. The H2i models provide full rated heating capacity even when the outdoor ambient temperature is as low as 5°F. Those models continue to provide reliable heat even with an outdoor ambient temperature of -13°F. Homeowners can manage intelli-HEAT systems with either third-party thermostats or Mitsubishi Electric’s versatile control options, including kumo cloud^®, kumo touch™ and select wired controllers.

Homeowners installing intelli-HEAT™ may also qualify for utility rebates. Homeowners should contact their local utility provider to determine what rebates, if any, may be available to them.

“The addition of intelli-HEAT to our product offering allows homeowners across the United States to use METUS’ products to transition to clean, energy-efficient heating and cooling solutions,” says North.

Addition of advanced “X” plate technology offers improved energy savings, reliability and comfort, delivers optimal thermal performance

As part of Bell & Gossett’s Building Better platform and commitment to sustainability, the addition of advanced, high-efficiency “X” plates enhance Bell & Gossett’s new gasketed plate and frame heat exchanger GPX P45, P55, P86 and P110.

Engineered for efficiency, “X” plate technology increases heat transfer thermal performance up to 20%, reduces surface area up to 20% and reduces materials up to 15%. Through advanced plate design and superior heat transfer characteristics, this new offering meets a critical need for the growing demand in modern HVAC applications.

“Bell & Gossett is committed to meeting modern commercial building HVAC challenges head-on with innovative heat transfer solutions,” said Jim Klimek, global product manager – heat transfer, Xylem. “The addition of ‘X’ plates to our GPX product portfolio will allow us to meet industry demand for high-efficiency solutions along with increased flexibility through a more compact design compared to a traditional plate heat exchanger.”

Standard options include a variety of high-efficiency plate corrugations, material options of 304SS, 316SS or titanium plates, and nitrile or EPDM gaskets. GPX models have higher surface area to volume ratios than conventional shell and tube heat exchangers. Application flexibility allows for maximum efficiency in less space, and the “true” countercurrent flow maximizes the mean temperature difference between fluids. Additionally, the unique plate design generates high turbulence resulting in high heat transfer coefficients.

Gasketed plate and frame heat exchangers (GPX) are available in the ESP-Thermal heat exchanger selection program. To learn more about Bell & Gossett’s Building Better platform and its commitment to future-proofed solutions, visit https://bellgossett.com/buildingbetter.

De-carbonization starts with energy savings

During the Huracan^TM Kickoff Celebration, REZNOR announced immediate availability of Huracan Destratification Fans, enabling North American owners of Commercial & Industrial Buildings to upgrade their building’s air comfort and lower their heating operation costs.

The Huracan fans come in four sizes that accommodate ceiling heights from 10-60 feet, covering almost all warehouses, commercial box stores, factories, athletic facilities and other large buildings, especially ones with obstructions like signage or lighting or power drops from ceiling. The new Huracan fans are designed to be installed in around 20 minutes, depending on the electrical source:

• They are lightweight – 22-43 lbs
• Have multi-position hanging brackets – only two threaded rods needed
• Have low power consumption (0.2-1.3 Amps)
• Existing 115, 208, 277,and 280V electrical can be utilized in most cases
• Designed to ASHRAE ANSI 55
• They can be controlled with these methods:

1. On/Off Wall Switches
2. Unit mounted thermostats
3. Thermostat controlled – up to 5 units in a zone
4. Multistage thermostat in combination with unit heaters or other space heating equipment
5. Sophisticated thermostatic interfaces that are compatible with most Building Management System protocols

The Huracan Destratification Fans are quiet (36-41 dba). They also feature an aesthetic, appliance grade, white steel finish that blends unobtrusively into the ceiling structures. When combined with Reznor’s newly-updated unit heater line, both heating options complement each other stylistically.

Destratification Energy Saving

Large buildings with taller ceilings all struggle with winter heat stratification as warmer air rises toward the ceiling. The Huracan Destratification Fans recycle warm air back down to the occupied space, which results in better air comfort, and less space heating run time of up to 30-50%.

“As energy efficiency becomes more important,” said Glen Steinkoenig, Product Manager, “the Huracan Destratification Fans will play a significant role in total operational efficiency for buildings, reducing their carbon footprint and creating more comfortable environments.”
