DEVICE for the preparation of drinking water in a passenger carriage

AREA 1

The utility model relates to water supply systems for passenger cars, namely, devices for the preparation of drinking water.

BACKGROUND

A device for the preparation of drinking water based on cryogenic installations 1 -f Sj.

The specified device comprises a cold water supply system (cold water tank) connected in series by pipelines, a boiler, and a cooler tank with a tap for disassembling chilled drinking water. An evaporator of the condensing unit is installed in the cooler tank. The condensing unit comprises a compressor, a condenser and an evaporator, connected by a piping system filled with freon.

A disadvantage of the known device is the presence of a cryogenic cooler for drinking water on freon, and, as a consequence, the lack of reliability and environmental hazard of the known device.

A device for cooling, based on the use of thermocouples (s, which can be used in a device for the preparation of drinking water in passenger cars, is devoid of T / above disadvantages.

In the specified device, the cooler is made in the form of a thermocouple whose cold junctions are installed in the refrigerating chamber.

A disadvantage of the known device for the preparation of drinking water with a thermoelectric cooler instead of a cryogenic cooler is the relatively low coefficient of performance (COP).

ESSENCE OF THE WHEATED MODEDA C while maintaining increased reliability and environmental safety of its use. . The solution to this problem is achieved by the fact that in a device for the preparation of drinking water containing a cold water supply system connected in series by pipelines, a boiler, a thermoelectric cooler and a chilled-water discharge valve, the thermoelectric cooler contains a thermocouple, cold junctions are installed in the first tank, the inlet pipe which is connected to the outlet of the boiler, and the outlet - to the chilled-water analysis tap according to the invention, a second tank with an inlet m and the outlet pipes, in which the hot junctions of the thermocouple are installed, and the second tank is connected by the corresponding pipes between the cold water supply system and the boiler. The introduction of these differences makes it possible to increase the efficiency of the potable water preparation device both due to preliminary heating of water before its boiling, and due to an increase in the thermal element of the thermocouple by pushing cooling of its hot junctions with cold water. KPAfgQE DRAWINGS The laziness of the utility model is illustrated by the design of the apparatus for preparing drinking water shown in FIG. In FIG. marked: I- tank for cooling water (first tank); 2,3 - inlet (filler) and outlet (drain) nozzles of the tank 1, respectively; 4 - tap for disassembling chilled drinking water (5t water taps - thermoelement (thermoelectric battery); 6.7 - cold and hot junctions of thermoelement 5, respectively; 8 - tank for water cooling hot junctions of thermoelement 5 (vtg swarm tank); 9, 10 - inlet (filler) and outlet (drain) pipe nozzles 8, respectively; II- cold water supply system (receiving tank); 12- boiler; 13- thermocouple electrical terminals; ". P BEST MODE FOR EXECUTING A MODERN MODE According to Fig. 1 device for preparing drinking water contains a follower but the cold water supply system 11 connected by pipelines, tank 8 with input 9 and output 10 pipes, boiler 12, tank 1 with input 2 and output 3 pipes, faucet 4, also contains a thermocouple 5 with input terminals 13, hot junctions of which are installed in the tank 8, and cold in the tank 1, the outlet pipe 10 of the tank 8 is connected to the input of the system 15. In the simplest case, the cold water supply system 11 is made in the form of a tank (tank) for cold water or the outlet pipe (faucet) of the main supply system of a passenger car. The operation of the proposed device is as follows: Cold water from the device 11 is supplied through the pipe 9 to the tank 8. In this case, when the thermocouple 5 is turned on, the OMYVESH water of the hot junctions 7 of the thermocouple 5 is heated and fed through the pipe 10 to the boiler и and to the hot water supply system iS. In the boiler 12, the preheated water is brought to the boiling temperature and fed through the pipe 2 to the tank 1. In the tank 1, the boiled water is cooled by the cold junctions 6 of the thermocouple 5 and is fed through the outlet pipe 3 to the faucet 4 for the analysis of chilled drinking water. The connection of the outlet pipe 10 of the tank 8 with the input of the main hot water supply system 11 can further improve the thermal operation of the proposed device. From the above it can be seen that preheating the water in the tank 8 reduces the cost of electric energy supplied to the terminals 14 of the boiler 12 to bring the heated water to a boiling point. At the same time, cooling the hot junctions 7 of the thermocouple 5 with running water through the tank 8 reduces the cost of electric energy supplied to the terminals 13 of the thermocouple 5 for cooling boiled water in the tank 1. At the same time, the total energy consumption for boiling and cooling boiled water is reduced, which leads to an increase in efficiency the proposed device in comparison with known devices for the preparation of drinking water. INDUSTRIAL APPLICABILITY. A useful model can be used for the preparation of chilled drinking water, mainly on ships and in railway transport. SPC EXPRESS is developing technical documentation for a prototype device for the preparation of drinking water.
