2020 was the second warmest year on record according to temperature data from the National Oceanic and Atmospheric Administration (NOAA). In addition, the average surface temperature in 2020 increased by more than 1 °C on land and in the ocean. Without question, climate change is THE issue on the minds of people in most countries around the world. If we only focus on Germany with regard to the heating, ventilation, and air-conditioning (HVAC) market, it becomes clear that climate change is the strongest driver for the HVAC industry.
The EU has set itself the goal of cutting a total of 65 % of all greenhouse gas emissions by 2030 (compared to 1990). Germany itself aims to be completely greenhouse gas neutral from a legal perspective by 2045. This means that, according to experts, around 3.6 trillion euro will have to be spent by 2045, or 150 billion euro a year.
The extent of this feat becomes clear to everyone when they focus on the approximately 19.5 million residential buildings in Germany alone. Of these residential buildings, a good 14.5 million will have to undergo energy renovation by 2045. Buildings account for a good 41 % of energy consumption and cause around 36 % of all CO2 emissions. Energy consumption in the transport sector, on the other hand, is only around 28 %. In the industrial sector it is 31 %.
The world's leading trade fair for water, heat, and air − ISH − is once again being held in Frankfurt am Main, Germany from March 13 to 17, 2023. The motto of the trade fair is "Solutions for a sustainable future". For 5 days, the trade fair will focus on innovations that contribute to achieving climate protection goals and enable responsible as well as efficient use of available resources.
High-quality digital solutions from JUMO which make control and networking possible play a role in a sustainable future. "And they increase living comfort," says Harald Schuppich, HVAC Market Segment Manager at JUMO. Heating and air-conditioning technology plays a major role in all areas of life, including industrial processes and building technology. When it comes to heating and air-conditioning systems as well as heat and cold meters, customers can rely on RTD temperature probe pairs, sensors, transmitters, thermostats, controllers, paperless recorders, and safety as well as automation systems from JUMO. These components reliably measure, control, and monitor temperature as well as pressure.
JUMO product: JUMO heatTHERM P300
Application: air-to-water heat pump
Here, the JUMO heatTHERM P300 monitors the electric flow heater of an air-to-water heat pump. The flow heater is used when the sole heat supply of the heat pump is no longer able to cope (as would be the case with very low outdoor temperatures). The electric flow heater then provides additional support with the building heat supply. JUMO heatTHERM P300 is an electromechanical safety thermostat and protects the electric flow heater against thermal overload with its exceptionally high electrical load capacities of up to 480 V AC and 30 A.
JUMO product: JUMO hydroTRANS S10
Application: Room air quality monitoring
Here, the JUMO hydroTRANS S10 monitors the typical room air parameters such as humidity, temperature, and CO2. JUMO hydroTRANS S10 is a reliable humidity and temperature transmitter with an optional CO2 module that cannot deny its high-quality industrial genes. The humidity transmitter operates according to a capacitive measurement method with a measuring range between 0 and 95 % relative humidity. A CO2 module with a measuring range of up to 10,000 ppm is indispensable for precise determination of indoor air quality. Clever placement of the CO2 module in the housing allows very short response times to be achieved so that rapid countermeasures, such as an increased fresh air supply, can be initiated.
JUMO product: JUMO heatTHERM-AT
Application: Home station for underfloor heating
Here, JUMO heatTHERM-AT monitors hot water preparation for the heating circuit of an underfloor heating system. The heat pump provides the home station with a typical heat carrier temperature of 55 °C to supply heat to the home. In addition to the modern electronic control technology, the DIN CERTCO-approved electromechanical safety temperature limiter (STB) JUMO heatTHERM-AT is responsible for thermal monitoring of the underfloor heating system. JUMO heatTHERM-AT is also an optional extra suitable for mounting on a "TH35" DIN rail (design type 7).
Typical JUMO customers want components for monitoring and controlling process as well as environmental influences. This can be, on the one hand, the protection of environmental conditions for good and healthy living conditions or, on the other hand, the protection of plant components against destruction due to overloading and underloading.
Monitoring can be performed using electromechanical switches (passive components) and a complete electronic solution. JUMO offers all products combined from a single source!
Energy experts keep emphasizing that in the future all possible energy sources in a city or district will have to be orchestrated in a hybrid grid due to limited availability. All energy sources – whether regenerative (wind power, solar power, biogas, geothermal energy, hydropower), fossil (coal, lignite, natural gas, petroleum), whether plants (combined heat and power plants, waste incineration plants, and nuclear power), whether vehicles with batteries (which are to be used here as storage/buffers in the future), whether modern fuel cells (hydrogen, methanol, butane or natural gas, energy surplus storage) and their distribution networks (district heating network, high-voltage networks, gas pipeline) – will then only be possible to allocate with digital assistance.
As a result, the HVAC industry is facing major challenges. Despite the difficult situation, the industry's transformation needs to be driven forward without losing sight of profitability. The industry therefore sees enormous growth potential in the coming years. As a system provider, JUMO wants to participate in this growth with its products and gain new customers.
