Definitions
- the subject of the utility model is a domestic water preheater that is fed with heating water from the gas and oil boilers, which are adapted for cooperation with the low-parameter boilers common in district heating supply.
- a domestic water heater which is fed with heating water from the systems in the boiler houses heated with gas or heating oil and is equipped with a plate heat exchanger set consisting of a few plate heat exchangers.
- the heat exchanger set is installed through connections in the hot water outlet collector and is connected to a stabilizer, which in turn is connected to the cold water collector by a connection piece and a Umlau umpe with a line for external circulation and a connection piece, a check valve and a pump for internal circulation is.
- the heat exchanger set consisting of a few plate heat exchangers is connected to the heating water supply.
- the task arose to create a construction of the domestic water preheater with a protective measure against the development of strains of legionnaire's disease bacteria, as well as corresponding solutions for eliminating the temperature build-up of the hot water and for maintaining the water temperature in the stabilizer tank from + 60 ° C across the entire height of the container.
- the developed preheater is also to be adapted to the cooperation with the condensation boilers of high technical efficiency.
- the domestic water preheater which, according to the utility model, contains a heat exchanger set consisting of some plate heat exchangers installed in the cold water collector and the hot water outlet collector and connected to the heating water supply line, is characterized by the fact that it has a mixing unit that has a thermostatic valve, an outlet collector , contains a control thermometer for monitoring hot domestic water at a temperature of + 60 ° C and a thermometer for circulating hot domestic water at a temperature of + 55 ° C.
- the mixing unit is connected to the stabilizer by an outlet nozzle and a line with water at an elevated temperature.
- the stabilizer is hydraulically connected by the plate heat exchanger set with a safety valve and with an expansion vessel from the cold water side.
- the preheater designed according to this utility model contains some construction solutions as well as technological solutions that protect against the formation of the bacterial flora, and especially against the formation of strains of Legionnaire's disease bacteria, whose intensive development takes place in temperatures from 20 ° C to 55 ° C.
- the mixing unit used with a thermostatic mixing valve enables maintenance in the stabilizer of the elevated temperature of + 70 ° C and, after mixing, allows feeding into the water intake system at the required temperature of + 60 ° C. Because only stainless steel is used in the system design, the deposit of scale and sediments is also included Legionnaire's disease bacteria are limited and periodic increases in the hot water temperature up to +80 --- 90 ° C and thus complete liquidation of the Legionnaire's disease bacteria in the preheater system are possible.
- the preheater is also fully adapted to cooperation with the condensing boilers with high technical efficiency. This guarantees very cheap cooling of the heating water by approx. + 35 ° C, because the prerequisite for the formation of condensation in the condensation boilers of the gas and oil boiler house is the constant maintenance of the return temperature below + 57 ° C. Reaching such temperatures in the previously used capacitance and continuous preheaters equipped with tubular heating coils is difficult and does not guarantee the complete condensation conditions.
- the domestic water preheater is connected by a shut-off valve 2 to the system 1 supplying the heating water from the gas and oil boiler house.
- the plate heat exchanger set 9 is connected to the line leading from the shut-off valve 2 through the feed pump 3 with control manometer 4, check valve 5, control thermometer 6 with capillary 6a, control manometer 7 and through automatic vent valve 8 ⁇ .
- the plate heat exchanger set 9 is connected to the return water system 10 by line 10a, control thermometer 11 with capillary 11a, control manometer 12 and shut-off valve 13, the plate heat exchanger set 9 being supplied with heating water by the system 1 and line, and the return water from the heat exchanger set 9 by the Line 10a is led into the return water system 10.
- the plate heat exchange set 9 is connected to the cold water system 14 by a shut-off valve 15, filter sludge trap 16, control manometer 17 on the bypass line of the filter sludge trap 16, check valve 18, expansion vessel 19 and safety valve 20.
- the plate heat exchanger set 9 is connected to the stabilizer 23 by line 21 and connection 22, and the stabilizer 23 is connected to the mixing unit Zm by outlet connection 24, lines 25 and 25a.
- the mixing unit Zm is equipped with a thermostatic direct action valve 26 connected to the cold water line 33 and with an output collector 27 with a built-in sensor 28 of the servomotor 29 for controlling the thermostatic valve 26, with a control thermometer 34 on the line 30 and with a thermometer 37a on the line 37 equipped for hot water circulation.
- the line 30 is connected to the outlet connection 31 and to the shut-off valve 32 for shutting off the hot domestic water with the required operating temperature of + 60 ° C.
- the circulation line 35 is connected to the lower nozzle 40 of the stabilizer 23 by a shut-off valve 36, line 37, circulation pump 38 and pressure line 39.
- the outlet connection 41 of this stabilizer is connected to the cold water system 14 by the connected pump 42 for internal circulation as well as by check valve 43 and pressure line 43a.
- the stabilizer 23 is equipped with an inspection port 44, a manometer 45 and a port 46, and in the bottom of this stabilizer a port 47 with an emptying and sludge valve 48 is installed, the revision port 44, the lower port 40 and the outlet port 41 in one plane lie, which goes through the axes of this nozzle.
