Pipeline from an external system should be inlet in the part of the building where a large number of water folding devices will be concentrated. As a rule, for shopping cen- ters with a lot of water consumers it is necessary to make not less than three inputs, each of them should be connected to different areas of an external ring water supply system in order to make the work of the system more reliable.The places for water folding fittings in shopping centers are the following. The water folding devices: mixers are placed in sanitary cabins of shopping centers. Usually, for for water saving in buildings with a big pass-through capacity per hour it is reasonable to use contactless mixers, which are turned on upon raising a hand with a help of motion sensor or light sensor. Another important argument in favor of such mixers is prevention of infections spread for the reason that the consumer doesn't touch the device, so, the risk of bacteria transmission via the device decreases. Such mixer supplies water with a demanded expense and temperature. As a rule, water for such mixers moves from the centralized internal water supply system of hot water, mixing up with cold water. If there is no centralized hot water supply system, it is possible to use hot water storage heaters in case of a small number of visitors or to reject mixers at all in favor of the cranes giving water of only one temperature (cold), which is also practiced.For the branch of economic and household the water receivers are used, which are present in sanitary cabins in most cases by toilet bowls, wash basins, urinals.

Use of the water supply system of special purpose in buildings

A water supply system of a special purpose is a necessary element in hot and cold shops of the industrial enterprises, office buildings and the medical centers, and also other rooms. The water supply systems of a special purpose, which give subsalty, sparkling water and water sated with oxygen, allow people to prevent, for example, strong dehydration of an organism, which is possible at big losses of water, especially in case of the people working in hot shops. Various elements of special drinking water supply system are given in the article, their main functions are described. Different types of the water folding devices pumping water to consumers, one of which is drinking fountain, are considered. Possible systems of water filtration, which can be established for quality improvement, are transferred. Among them the great role is played by membrane technologies and the return osmosis, which is widely applied now. Today there is a possibility of construction, both the centralized water supply system of a special purpose, and local. Besides, the least is a more preferable option taking into account capital expenditure for construction and operation, and also it can lead to solid resource-saving as a result of the electric energy saving going for water heating in heaters. Automatic machines of drinking water for a local water supply system of a special purpose have indisputable advantages. They are capable to carry out several functions at the same time, and also to distribute water to consumers. It allows placing all the necessary equipment, which will be well in harmony with the environment in their small and compact case, and will fit into any difficult interior of the room. Also they are very easily connected to the systems of an internal water supply system by means of a propylene tube that allows to change their sposition in space and to transfer to any place of the room with fast installation of equipment. Also the ecological effect was proved upon transition from coolers on machine guns of drinking water that allowed refusing the order of plastic bottles, which after use start accumulating on dumps, polluting the environment.
