Meyer & Meyer Sanitär + Heizung Zürich Oerlikon central vacuum cleaners

Centrally installed systems (central vacuum cleaners or domestic vacuum systems) consist of the suction unit, which is installed stationary (usually in the basement or garage). From there, a pipe system is laid throughout the house, to which the suction pipe with the brush head is connected via a hose line. Dust cans can be used to remove dust directly instead of a dustpan. After being cleaned in a cyclone filter or lamella filter, the sucked-in air is usually blown out of the house. The odor nuisance caused by the turbulence of the exhaust air in the room, as with conventional vacuum cleaners, is eliminated, which is particularly beneficial for people with allergies to fine dust. The noise of such an appliance is correspondingly low and the overall energy balance is also somewhat better than with hand-held vacuum cleaners. This design is already around 100 years old, but has only become established in certain regions. These include the Scandinavian countries and North America. Central vacuum cleaners usually last longer than handheld vacuum cleaners, which is why it is important to install and maintain the system carefully. When planning a domestic vacuum cleaner system, it is important to ensure a suitable combination with a ventilation system.

Meyer & Meyer Sanitär + Heizung Zürich Oerlikon solar systems

Thermal solar systems - such as flat solar collectors and vacuum tube collectors - can be used to heat drinking water (shower and bath water) and to generate heat for space heating and for cooking (process heat), for example. A specially coated absorber surface within a so-called thermal "collector" (= collector) is heated by electromagnetic solar radiation in the visible and infrared range of the spectrum. A liquid or, more rarely, a gas (e.g. air) flows through the tubes of the absorber and absorbs this heat (heat transport medium). By means of a pump or a fan - sometimes only by the buoyancy of the heating - this medium is directed to a storage tank, where it is cooled down and returned to the inlet of the absorber (circulation). In Central Europe, depending on the region, solar thermal systems can usually cover 50 to 60 percent of the energy required to heat drinking water[1]. Higher contribution margins or use in building heating technology are also possible. The solar thermal system can support the heating system, but the contribution margin depends on various boundary conditions (demand, storage tank, medium, etc.). The Swiss engineer Josef Jenni demonstrated what is possible as early as 1989 in the Oberburg solar house project[2]: with the appropriate effort, one hundred percent of the heating requirements of a single-family house can be covered by solar energy, and this can also be achieved with an apartment building. Solar thermal systems can also be used to generate process heat in industry and commerce. In the food industry in particular, there are many applications for which the necessary temperatures of 60 to 100 °C can also be generated with collectors. Household applications (solar stoves) are uncommon in Europe, but have been implemented in some projects in Africa and India. The supply of district heating networks using solar energy is now widespread in Denmark, Sweden and Austria. Special collectors for large-scale systems are used to provide solar support for conventional energy supplies in around 100 towns and cities. In many small networks, solar heat replaces a biomass boiler in summer. But there are also remarkable approaches in urban areas, for example in Graz. Another area of application is the provision of cooling (solar air conditioning). Chillers powered by heat from collectors make particularly efficient use of solar energy, as the highest cooling demand coincides with the strongest solar radiation. There are now over a hundred model systems for research and demonstration purposes, and large commercial projects have also been realized in recent years. The most prominent installations are in Qingdao/China in the Olympic Sailing Village for 2008, at the Renewable Energy House in Brussels, in Lisbon at the main building of the Caixa Geral de Depósitos, currently the largest solar cooling system in the office sector worldwide, and in Priština/Kosovo at the building of the European Agency for the Reconstruction of Kosovo.

Meyer & Meyer Sanitär + Heizung Zürich Oerlikon heat pumps

The heat pump extracts heat from a reservoir (air, groundwater, ground) and thus cools the heat source. As long as the absolute temperature of the source is above absolute zero of -273.15 °C, heat can be extracted from the source, but only along a temperature gradient. However, the efficiency of the heat pump - expressed in the coefficient of performance - decreases as the temperature of the source drops. The heat pump is technically constructed like a refrigerator, with the difference that the warm side of the heat pump (condenser of the heat pump) is used for heating. The lower the desired temperature difference between the heat reservoir (e.g. groundwater of 7 °C) and the "flow temperature" (= "heating flow" = the temperature at which the water is fed into the heating circuit), the more efficient the use. As the temperature range increases, the coefficient of performance of the heat pump decreases. Most heat pumps are designed for flow temperatures up to a maximum of 60 °C. Heat sources for heat pumps are water, moist soil or moist air. If the evaporation temperature falls below 0 °C, ice forms on the heat exchanger surfaces. Ice is an insulating layer and significantly impairs heat transfer. Thanks to newer technologies (gas cooling), heat pumps that extract heat from the outside air can currently be used effectively down to -25 °C outside temperature (see section on refrigerants; e.g. Mitsubishi.[1] A heat pump that extracts heat from a water tank at a depth of 10 m (approx. 5 °C ground temperature) can be operated regardless of the outside temperature (below the freezing point of water because ice is lighter than water and therefore floats on the surface). Energy must be applied ("input") for the heat yield. The ratio of energy yield ("output") to input is called the coefficient of performance. A coefficient of performance greater than 4 is considered economical. This energy can be supplied by electricity or gas. During combustion, the gas can drive an absorption or adsorption chiller or be used in a motor that drives a compression chiller like an electric motor.
