The HVAC industry, responsible for heating, ventilation and air conditioning, plays a key role in our daily lives and in industry. Why is it so important? ? Imagine living for a while without the right temperature, fresh air or proper humidity - not only in our homes, but also in workplaces, hospitals, schools or factories. Dampness and a lack of indoor air circulation can lead to lethargy, increased allergic symptoms and moisture problems such as fungi and mould. In industry, proper climate control inside halls or warehouses is essential to maintain product quality, employee safety and the efficiency of production processes. At JUMO, we are well aware of this. For 75 years, we have been working with the HVAC industry, providing advanced measuring devices and automation systems dedicated to various applications within this industry such as condensing, solid fuel and pellet boilers, combined heat and power plants, air conditioners and heat pumps. In this blog post, we will introduce them in detail. Read on to find out how JUMO technologies can help optimise and reduce the operating costs of your HVAC systems, while ensuring safety and efficiency!
HVAC stands for Heating, Ventilation, and Air Conditioning. HVAC systems provide optimal conditions for machinery, equipment and employees in industrial facilities.
Components of the HVAC sanitary engineering industry:
HVAC (sanitary installations) are integrated solutions that monitor and regulate environmental conditions in real time. In this era of striving for energy saving and green solutions, HVAC technology is becoming increasingly advanced, combining efficiency with economy.
HVAC stands for "Heating, Ventilation, and Air Conditioning".
Condensing boilers utilize fossil fuels such as gas or oil for heat production. The fuel is burned in the boiler's chamber, generating thermal energy and exhaust gases. This heat is transferred to water flowing through pipes. Thanks to preheating the water in a heat exchanger using the exhaust gases' heat, these boilers achieve high efficiency.
Precise measurements are crucial in condensing boilers. The domestic water must be maintained within a strict temperature range of 55-60°C. Our screw-in or plug-in resistance temperature sensors are suitable for this application. However, our offerings are not limited to temperature measurement – we provide a complete measurement system for condensing boilers, covering all necessary parameters from pressure to humidity. Precise measurements of these values not only enable optimal system operation but also early detection of potential problems. The result is increased device longevity and reduced risk of costly failures.
Among the JUMO products dedicated to this segment, it is worth mentioning:
JUMO STB/STW: Temperature limiter and monitor for safe boiler operation
JUMO miroTRON: thermostat/controller with PID controller function, which enables condensing boilers to adapt to rapidly changing conditions
Solid fuel boilers, utilizing materials such as firewood, convert them into thermal energy, which is then transferred to the heating water. A key aspect of their operation is monitoring the exhaust gas temperature, especially when they are used in conjunction with a condensing boiler in a bivalent mode. With exhaust gas temperature monitors like the JUMO STM-RW-2, it is possible to precisely track the temperature in the solid fuel boiler’s exhaust pipe. When it reaches 80°C, the system automatically shuts down the condensing boiler, ensuring safe and optimal operation.
Heating with solid fuels inevitably results in high temperatures generated by the flames. In such an environment, the reliable and continuous operation of all safety systems is particularly important. At JUMO, we always keep our finger on the pulse of technology that ensures the safety of boiler rooms.
Some of our products dedicated to solid fuel boilers include:
JUMO flowTRANS US: Ultrasonic flow meters for liquid flow monitoring
JUMO heatTHERM: Panel-mounted thermostat for precise control of the temperature inside the boiler.
Pellet boilers are an ecological and efficient alternative to traditional heating systems. Using a renewable energy source in the form of wood pellets, these boilers provide clean and sustainable heating. In larger pellet heating systems, wood pellets are delivered to the boiler via a conveyor or suction device. The combustion is initiated electrically. The released thermal energy heats water, while the exhaust gases pass through a heat exchanger, transferring their heat before being expelled through the chimney. Precise measuring and control technology is essential for optimal performance and safety of pellet boilers.
Temperature visualization: As the thermal output of the pellet boiler increases, constant monitoring of temperatures becomes crucial. Thanks to the JUMO diraVIEW series of digital indicators, users can check the current process temperature at any time. Set minimum and maximum values allow for reliable process control, and the change of color in the alarm text further facilitates monitoring.
Key JUMO products for pellet boilers:
JUMO MIDAS S05: OEM pressure transmitter for system pressure monitoring
Thermocouples for monitoring the temperature of pellet boilers
Combined heat and power (CHP) plants represent the cogeneration concept, which involves simultaneous production of electrical and thermal energy in a single process. This solution is much more energy-efficient compared to traditional methods of energy production. In CHP plants, the primary energy source is usually an internal combustion engine or a gas turbine that drives an electric generator. The heat generated during this process, instead of being wasted, is recovered and used to heat water or other thermal media.
JUMO technology plays a key role in optimizing and ensuring the safe operation of CHP plants. Advanced JUMO measuring devices monitor key parameters such as temperature and pressure in various parts of the system. This is especially important in the cooling system of the internal combustion engine of a CHP plant, where the right pressure and oil temperature are essential to prevent damage, such as bearing failures. Thermostats, like those offered by JUMO, not only track critical temperature values but can also automatically shut down the system in emergency situations.
Key JUMO products for CHP plants include:
JUMO VIBROtemp: vibrationsfeste Temperaturfühler
JUMO LOGOSCREEN 601: Elektronischer Schreiber mit Touchscreen zur Visualisierung und Archivierung von Prozessdaten.
Air conditioners and heat pumps operate on a similar principle, utilizing thermodynamic processes to transfer heat from one place to another. In simple terms, both devices use a refrigerant that circulates in a closed loop and undergoes a cycle of compression, condensation, expansion, and evaporation.
In air conditioners, heat is extracted from the interior of a space and expelled outside, thereby cooling the air inside the building. Heat pumps, on the other hand, can operate in both directions - cooling spaces in the summer and heating them in the winter, by reversing the flow direction of the refrigerant.
External units of air conditioners are susceptible to frost, which can lead to equipment damage. The JUMO frostTHERM-AT is an advanced thermostat that detects subtle signs of freezing. Thanks to a specially designed capillary line that covers the external unit, it can detect "frost paths" as short as 30 cm. When it detects that the temperature is approaching the freezing point, the thermostat activates appropriate mechanisms - this could be turning on the heating system or completely shutting down the installation. Such action minimizes the risk of condensation and damage caused by low temperatures.
