MCE to Bring Essence of Comfort to the World

mce

Mostra Convegno Expocomfort (MCE) 2022 will be held from June 28 to July 1 at Fiera Milano, Milan, Italy. For this edition, MCE will present a new digital platform from June 28 to July 6.
MCE is a global event where companies in the heating, ventilation, air conditioning, and refrigeration (HVAC&R), renewable sources, and energy efficiency sectors gather and showcase the latest technologies, solutions, and systems for smart buildings in the commercial, industrial, and residential sectors.
MCE 2022 will focus on ‘the Essence of Comfort’: Indoor Climate, Water Solutions, Plant Technologies, That’s Smart, and Biomass. The Indoor Climate segment will feature the entire spectrum of technologies designed to create the best comfort conditions by managing all factors related to health and wellness. It will also feature advanced, energy-efficient, and integrated systems with a strong renewable component to guarantee both pleasant and productive facets, but also safe and sustainable environments. Moreover, it will provide a variety of solutions to meet the latest needs of plant design, installation, and management.

For the show, lots of famous brand demonstrates their products highlights, let’s list as below:

 Air control:

Air Control, a leading Italian company in the air distribution and sanitation market with photocatalytic oxidation (PCO) technology, will present its complete selection of monitoring and sanitizing devices for indoor air in buildings.

Among them, AQSensor is a device for monitoring and ensuring optimal control of indoor air quality (IAQ), deploying both Modbus and Wi-Fi communication protocols. It offers autonomous ventilation control, real time data analysis, and energy savings, and adopts certified sensors.

Area Cooling Solutions:

Area works hard towards developing sustainable products. In 2021, it introduced a unique solution to the market: the iCOOL 7 CO2 MT/LT, a low carbon footprint solution for all commercial refrigeration applications.

Bitzer
Bitzer Digital Network (BDN) is a digital infrastructure for different stakeholders using Bitzer products. With BDN, they can manage their Bitzer products both from an overall perspective and in every detail.

CAREL
CAREL Industries will be presenting the latest solutions focused on improving energy savings and connectivity, with a complete offering ranging from the control of heating, ventilation, and air conditioning (HVAC) systems of residential applications, to solutions for the air conditioning and humidification of healthcare, industrial, and commercial environments.

Daikin Chemical Europe
Daikin Chemical Europe has put in place a manufacturing process that focuses on sustainability and circularity of refrigerants. The reclamation process and the thermal conversion allow the company to close the loop at the end of life of the refrigerants.

Viessmann Group to Invest €1 Billion in Heat Pumps and Green Solutions

On May 2, 2022, the Viessmann Group announced that it will invest €1 billion (about US$ 1.05 billion) in the next three years to extend its heat pump and green climate solutions portfolio. The investments are targeted to expand the family company’s manufacturing footprint and research and development (R&D) labs, thereby also strengthening Europe’s geopolitical energy independence.

Prof. Dr. Martin Viessmann, chairman of the Board of Directors of Viessmann Group, underscored that “For more than 105 years, our company has been a family for positive change with a clear focus on energy efficiency and the development of new technologies such as the first heat pump generation in 1979. Our historic investment decision comes at a time where we build the right foundation for the next 105 years – for us and, even more important, for generations to come.”

Viessmann Group

Max Viessmann, CEO of Viessmann Group, highlighted that “Unprecedented geopolitical developments need unprecedented replies. We all need more speed and pragmatism in order to fight climate change and to rethink energy generation and use of tomorrow, in order to strengthen Europe’s geopolitical independence. Consequently, we are now accelerating our growth with dedicated investments in heat pumps and green climate solutions. At Viessmann, all 13,000 family members are relentlessly committed to co-creating living spaces for generations to come.”

The latest business development of the Viessmann Group underlines the strong product-market-fit in its green climate solutions. Despite negative effects from the pandemic and challenged global supply chains, the family business successfully managed to grow significantly in another year of crisis. The group’s total revenue in 2021 reached a new record high of €3.4 billion (about US$ 3.58 billion), compared with €2.8 billion (about US$ 2.95 billion) the previous year. The significant growth rate of +21% was especially driven by increasing demand for premium heat pumps which jumped +41%.

HVAC Trending

 Energy Recovery Wheels Save Energy and Reduce HVAC Loadssave energy

Any opportunity an engineer may have to recover energy in the design of an HVAC system can pay big dividends in offsetting system first costs as well as the total operation costs of the building. As energy costs continue to rise, and studies indicate the average HVAC system consumes 39% of the energy used in a commercial building (more than any other single source), energy-efficient HVAC design has the potential to bring big savings.

The Fresh Air Balance

ASHRAE Standard 62.1-2004 prescribes minimum ventilation (fresh air) rates for acceptable indoor air quality. The rates vary based on occupant density, activity levels, floor area and other variables. But in every case, it is agreed that proper ventilation has the greatest impact on indoor air quality and the subsequent prevention of sick building syndrome in occupants. Unfortunately, when fresh air is introduced into a building’s HVAC system, an equal amount of treated air must be exhausted to the exterior of the building to maintain proper system balance. At the same time, the incoming air must be heated or cooled and dehumidified to the requirements of the conditioned space, which impacts the system’s overall energy efficiency.

A Solution to Energy Savings

One of the most effective ways to offset the energy use penalty of treating fresh air is with an energy recovery wheel (ERW). An energy recovery wheel works by transferring energy between an exhaust (indoor) airstream and an incoming fresh airstream. As the air from both sources passes through, the energy recovery wheel uses the warm exhaust air to preheat the cooler, incoming air (winter), or to precool the incoming air with cooler exhaust air (summer). They can even reheat supply air after it has already been cooled to provide an extra layer of dehumidification. This passive process helps precondition the incoming air to be closer to the desired requirements of the occupied space while providing significant energy savings in the process. The amount of energy transferred between the ERW and the energy levels of the two airstreams is called “effectiveness.”

Using energy recovery wheels to reclaim energy from exhaust air can provide significant savings to the building owner while notably reducing the load on the HVAC system. They can help reduce the use of renewable resources, and may help a building qualify as “green” in some locations.
