DE2105076C3 - Water heater working according to the vacuum evaporation principle - Google Patents

Description

Instead of the two transducers 15 and 20, a single transducer is of course also used provide that in a known manner on two different Response values can be set, whereby the lower response value after switch-off the circulation heating becomes effective. The pot temperature can be done by temperature-sensitive transducers (thermostats) as well as by Transmitters that respond to vapor pressure are regulated.

y! 2 that each of the two switches or one of the switches patent claims: can be switched on to a different heating power 1 ^ at each response value. When the switch is switched off, 1. According to the principle of evacuation of the vacuum, arleufbeaungsartlage through the switch a lower one barking water heater, in which the heating output can be switched on in one s. evacuated, partially filled with water, by The invention can be used in the manner verw.rkhch.wer- One burner heated container, one for that from each of the switches a solenoid valve for Brewing water preparation serving boiler and the Heizmittelzufubr is controlled and the magnetic independent heat exchanger of a valve in parallel heating medium supply units. Urnlaufbeizung are arranged, the return flow i ° gen., line a pipe coil arranged to boiler Advantageously, the flow cross-sections having, the nozzle temperature adjustable by the solenoid valve, a temperature- and pressure-sensitive regulator. ler is adjustable, in series rait the winding example with reference to the drawing Development of the fuel supply to the burner is explained in more detail. The drawing shows a warm iierrscbenden solenoid valve and parallel to a water heater with a schematic indicated the other two from the steam temperature or the heating and hot water system. Steam pressure controlled switches are arranged, the water heater consists of an eyaku- according to main patent 1954 296, thereby ge ied container 1, which with a heat insulating layer2 indicates that each of the two scarf * ° is provided. In the container 1 there is a relative ter (16, 21) or one of the switches for each small amount of water 3, which when heated by a Response value to a different heating output a heat source 4 forms steam. In the steam room 5 of the is switchable. Container 1 is a domestic water boiler6 2. Warmwasserberc.ter according to claim 1, da- and a Wärmeaustauscher7 one by a heating characterized in that when switched off 25 body 8 and a circulating pump 9 indicated circulation heating system by the switch (21) circulation heating. The boiler 6 is connected to a cold water, higher or lower heating output line 10 and a tap line 11 ,
is switchable. A flow line leads from the heat exchanger 7 3. Water heater according to claim 2, data 12 to the radiators 8, and of these (8) characterized in that from each of the switching 3 ° leads a return line 13, in which the Umter (16, 21) a solenoid valve ( 17, 17 a) is switched on for the circulating pump 9, is controlled to a heating medium supply in the boiler 6, and the solenoid pipe coil 14 and from this (14) to the valves in parallel heating medium supply lines heat exchanger 7 back. The water of the back (18.18 a) lie. Running line 13 is therefore in the coil 14 in 4. Water heater according to claim 3, da- 35 heat exchange with the service water filling of the characterized in that the flow cross boiler 6. Sections of the solenoid valves (17, 17 a) adjustable. In the steam chamber 5 there is a temperature are. or pressure responsive transducer 15, the when exceeding a preset steam 40 temperature on ", switch 16 actuated. The switch 16 is in the circuit of an adjustable magnet valve 17, which is de-energized at a steam temperature of for example 105 ⁰ C and the heating medium supply line 18 shuts off. In series with the switch 16, a room thermostat 19 or some other switch that switches off the circulation heating is provided. In the steam space 5 there is also a second one The main patent 1 954 296 relates to a measuring transducer 20 which, at a low steam temperature of 90 ° C, for example, operating on the vacuum evaporation principle, actuates a water heater in which an evacuated switch 21 is actuated through which the also partially filled with water a burner-face solenoid valve 17 a is made currentless and the heated container can be shut off a Heizmittclzufuhrleitung 18 "serving water heater and an independent boiler. The switch 21 lies parallel to the switch 16, a circulation heater, and the room thermostat 19.
the return line a in the boiler disposed 55 during normal heating operation of the measuring coil takes over, whereby the steam temperature value generator 15 and the switch 16, the control of the regulator is adjustable by a temperature- and pressure-sensitive steam temperature in the steam chamber 5 to 105 ° C., wherein In series with the winding of the return water from the circulating heating, a pipe coil 14 that controls the fuel supply to the burner ensures that the solenoid valve and two parallel water in the boiler 6 are cooled and that there is no inadmissible effect on the steam temperature or steam pressure - Assumes high temperature. However, will be arranged by the controlled switch. Room thermostat 19 or, in summer operation, the The invention is based on the object of being switched off when the heating is running, so the measuring device of this type takes over the heating power of the respective value transmitter 20 with the switch 21 regulating the heat demand for the preparation of hot steam temperature 5 to a lower value, e.g. B. adjust water or for heating. 90 ⁰ C, so that the domestic water in the boiler 6 despite According to the invention, this is no longer present in the case of hot water serbereiter achieved according to the main patent by not being able to assume an inadmissibly high temperature.
