The method of operation of the installation of sanitary hot water and installation of sanitary hot water

Abstract

The invention solves the problem of hot water flow in a domestic hot water installation. The subject of the installation according to the invention is that on a third cold water branch (13) that feeds the heating device (1) a control switch (4) is installed, said switch (4) is connected by control system (11) with hot water flow forcing device (3) set on a second hot water circulation branch (2).

Claims

1. A method of operation of the installation of sanitary hot water with gravitational or forced circulation, that has water as a heating device, characterized in that in the moment of opening of a tap, circulation in hot water branch is initiated, where the intake of hot water is detected on a cold water inlet branch by a control switch.

2. The method according to claim 1, characterized in that the period of water circulation forcing is ended by closing of the tap.

3. An installation of sanitary hot water that has a water heating device, a water flow forcing device in circulation circuit, a sensor that reacts to a flow of liquid and a temperature sensor characterized in that on a third cold water branch that feeds the heating device a control switch is installed, said switch comprising an element that is activated under the influence of water flow, which is coupled by the second sensor with a control system, which is connected with the water flow forcing device set in a second hot water circulation branch.

Description

EXAMPLE 1

On the Method

[0011] The method of operation of the installation is additionally explained on schematic on FIG. 1, said installation has two hot water branches 5 and 2 and third cold water branch 13. In the third branch 13, on the inlet to heating device 1, control switch 4 is installed, and on the second hot water circulation branch 2 a pump 3 is installed. Opening of a tap 6 causes the flow of water in the third cold water intake branch 13, which is detected by control switch 4. Water flow activates the control switch 4, which activates the pump 3 installed on the second branch 2. Pump 3 causes the circulation of hot water also in the first branch 5, thus accelerating the arrival of water with desired temperature to tap 6.

EXAMPLE 2

Regarding the Device

[0012] Example of hot water installation according to the invention is shown on the drawings, where FIG. 1 shows schematic diagram of the installation with control switch installed on the inlet of the exchanger, and FIG. 2 shows schematics of control switch.

[0013] A second hot water circulation branch 2 is connected to heating device in form of heat exchanger 1, said branch 2 having a pump 3 forcing the flow of water in the branch 2. On the inlet to the heat exchanger 1 there is a control switch 4 electrically connected with pump 3. On the first hot domestic water collection branch 5 there is a tap 6.

[0014] Additionally, on the second branch 2, before the inlet of circulating water to heat exchanger 1, first water temperature sensor 7 is installed. Control switch 4 has a turbine 8 set inside of the body 9. Turbine 8 is coupled by the second water flow sensor 10 with control system 11 equipped with the timer 12. The first temperature measuring sensor 7 is connected to the control system 11. As shown on FIG. 2, control switch 4 is placed on the third cold water branch 13 to the exchanger 1.

[0015] When the water flow is set by tap 6 movement of hot water in first water intake branch 5 arid third cold water branch 13 is started, that feeds the device 1 that prepares hot domestic water. Movement of the water forces the rotation of turbine 8, that activates sensor 10, that sends the signal to electronic system 11, which activates pump 3. The operation time of the pump 3 is regulated by timer 12 or electrical system 11. Electrical system 11 has the task to control further need for work of pump 3 by water flow. After set time passes or when there is no water flow through switch 4, or when the water in branch 2 reaches desired temperature set on sensor 7, pump 3 is turned off.
