2 is an example of a hot water heating integrated piping system using a hot water supply line supplied from a central heating heat source supply side and an area such as an apartment house or building according to an embodiment of the present invention.

Hereinafter, a detailed description will be given of a'hot water heating integrated piping system using a hot water line as a heat source' according to an embodiment of the present invention.

In terms used in the description of the present invention,'heating load side' may mean including'central room, kitchen, and individual rooms'. The'current temperature' of the heating load side can be used interchangeably as'indoor temperature' or'heating water temperature' or'return temperature'. 'Heat source water' is a heat source supplied from the heat source supply side and can be used interchangeably as'heating water'.

The'heating return' may be a fluid that is returned through the heating load side. 'Water supply' may be a fluid used to produce hot water supplied from the outside.

1 is an example of a hot water heating integrated piping system using a hot water supply line supplied from a central heating heat source supply side and an area such as an apartment house or building as a heat source. The hot water supply heating integrated piping system using the hot water supply as a heat source of FIG. 1 is an example in which the hot water supply and the heating flow path are integrated into an integrated pipe.

The hot water heating integrated piping system (A) using the heat source of the hot water supply line supplied from the area and the central heating heat source supply side of an apartment house or building as shown in FIG. 1 is at room temperature using a heat source supplied through the hot water supply line 110 The water supply 102 may be mixed through the faucet 116 and tapped with hot water 101 or heat exchanged through the heat exchanger 103 to be supplied as heating water to each room of the heating load side 120.

The hot water heating integrated piping system (A) using the existing hot water supply line as a heat source will be described with reference to FIG. 1 by dividing it into heating and hot water supply.

In heating, the heating water that is heat-exchanged from the hot water supply line 110, which is the heat source supply side, is driven by the circulation pump 111 according to a control signal from a controller (not shown), passes through the heat exchanger 103, and passes through the isolation valve 112 to the distributor. It is supplied to the heating load side 120 through 113 to raise the current temperature of each room of the heating load side 120 and to be returned through the heating return pipe 140.

The heating water supplied to the heating load side 120 may be supplied to each room of the heating load side 120, for example, a central room/each room, etc. through the operation of the actuator of each valve provided in the distributor 113.

In the hot water supply, the heat source water supplied from the hot water supply line 110, which is the heat source supply side, is discharged to the hot water 101 through the hot water supply line 114 when the valve 115 installed in the hot water supply line 114 is opened.

In the case of the existing hot water heating integrated piping system (A) using a heat source supplied from a hot water supply line, which is a central heating heat source supply side, and an area of an apartment house or building as shown in FIG. 1, the maximum temperature of the hot water temperature ( t_max) is supplied by limiting the temperature of the heat source itself in order to control and supply the hot water temperature to a temperature of about 55°C or less, which is an appropriate temperature range that can prevent human burns.

Accordingly, when heating is supplied, the heating supply temperature of the heating water is supplied without exceeding the maximum temperature (t_max) of the hot water supply temperature limited to the burn-prevention temperature range. When heating water supply is required, it is difficult to supply high-temperature heating water corresponding thereto.

In addition, the existing hot water heating integrated piping system (A) using the heat source supplied from the hot water supply line uses hot water from the hot water supply line supplied from the heat source, and for heating, heat-exchanged heating water is supplied to the heating load side 120, and hot water supply Silver is intended to be used by mixing the hot water 101 and the water supply 102 through the faucet 116, but when the temperature of the hot water 101 is high, the maximum temperature (t_max) that can be discharged to the faucet 116 is Since it can be tapped at a high temperature, there is always a risk of burns.

The present invention provides a hot water supply line capable of supplying hot water at a hot water temperature lower than burn protection even when the hot water heat source temperature is increased in a hot water heating integrated piping system using a hot water supply line as a heat source and freely supplying heating water at a required heating temperature. It is presented as an integrated piping system for hot water heating as a heat source.

The present invention is presented to improve heating performance relatively simply without adding or expanding facilities such as pump performance and pipe diameter in a hot water supply heating integrated piping system using a hot water supply line as a heat source.

The present invention is presented so as to be able to freely supply heating and hot water as much as a required amount of heat in a hot water heating integrated piping system using a hot water line as a heat source.

2 is an example of a hot water heating integrated piping system using a hot water supply line supplied from a central heating heat source supply side and an area of an apartment house or building according to an embodiment of the present invention.

As shown in FIG. 2, the hot water heating integrated piping system 100 using the hot water supply line supplied from the central heating hot water supply line side and the area such as an apartment house or building as a heat source receives a heat source through the hot water supply line 110. It may be configured to supply the hot water 101 and the heating water of the heating load side 120.

In addition, a first mixer 200 is provided in the hot water supply line 110 to adjust and supply the hot water temperature to a maximum temperature (t_max) or less by mixing the hot water heat source of the hot water supply line 110 and the water supply 102 supplied from the outside. It can be provided and configured.

In addition, the first mixer 200 controls the flow rate of the heat source flowing to the hot water supply line 110 so as to supply the temperature of the hot water supply 101 below the maximum temperature t_max. It can be configured by installing the valve 210.

Here, the maximum temperature (t_max) of the hot water 101 may be a hot water temperature set in a controller (not shown) at a temperature of about 55° C. as a temperature at risk of burns to the human body generated when the hot water to be tapped is contacted.

'118' is a'heating supply pipe' that supplies heating water. '119' may be on/off valves that regulate the flow of fluid. '121' may be a'external calorimeter'. '122' is a'drain valve'.

In addition, the first mixer 200 includes a flow control valve 210 that controls the flow rate of a heat source supplied to the hot water supply line 110, and a water supply that induces mixing by supplying water supplied from the outside to the hot water supply line 110. It may be configured to include a hot water temperature detection sensor 230 for detecting a hot water temperature mixed with water supplied to the water supply mixing pipe 220 through the mixing pipe 220 and the flow control valve 210.

Through the detection value of the hot water temperature detected through the hot water temperature detection sensor 230, the opening amount of the flow control valve 210 can be adjusted through the controller, and at the same time, the water supply amount of the water supply 102 supplied from the outside is the valve 119 ), the maximum temperature (t_max) of the hot water supply 101 can be adjusted to be less than the maximum temperature (t_max) set temperature of the hot water supply 101 set in the controller.

Here, a flow meter (not shown) that detects the flow rate of hot water supplied from the hot water supply line 110 to the first mixer 200, and a water supply temperature detection sensor (not shown) that detects the temperature of the water supply are further configured, The opening degree of the flow control valve 210 may be precisely controlled according to the set temperature.

In addition, between the first mixer 200 and the hot water 101 may be configured to include a second mixer 300. The second mixer 300 may include a faucet 310 installed in the hot water supply line 114 to receive water supply through the water supply line 130. In addition, the second mixer 300 may be configured to include a check valve 320 installed in the water supply line 130.

Here, the check valve 320 may be installed to block the supply of unnecessary water supply 102 by controlling the flow of the water supply 102 to the water supply mixing pipe 220. In addition, the check valve 320 may prevent reverse flow of the hot water supplied through the hot water supply line 110 or the hot water supply line 114 toward the water supply mixing pipe 220, in particular, the first mixer 200 and the second mixer. It is installed between 300, it is possible to prevent reverse flow of hot water from the first mixer 200 side to the second mixer 300.

In addition, the hot water supply line 110 and the heating return pipe 140 are connected to a heating water supplement line 400 for supplementing heating water, and the heating water supplement line 400 has one end of heating water from the heating load side 120 It may be configured to be connected to the heating return pipe 140 for returning and the other end to be connected to the hot water supply line 110 for supplying a heat source. Here, the check valve 320 is configured to supply the heat source of the hot water supply line 110 through the supplementary line 400 to increase the flow rate of the heating water flowing through the heating return pipe 140 to supplement the heating. It may be controlled by the controller to block the reverse flow of the hot water heat source supplied to the water return pipe (140).

In addition, the first mixer 300 for supplying the hot water 101 has a flow meter 240 for calculating the hot water charge, and the heat source return pipe 150 for returning the heat source has a calorimeter sensor 420 for detecting the heating charge. ) Can be configured so that the charge for heating the hot water pipe can be easily and simply calculated.

The hot water supply heating integrated piping system 100 using the hot water supply line as a heat source according to the embodiment of the present invention configured as described above has a temperature range of about 55° C. lower than the maximum temperature t_max for the hot water supply line 110 to prevent burns. It is possible to efficiently solve the problem of the hot water heating integrated piping system 100 using an existing hot water supply line set to be supplied from as a heat source.

For example, in the conventional case, even though the heat source temperature of about 55°C, which is the maximum temperature (t_max), is supplied through the hot water supply line 110, the actual heating temperature of the heating water exchanged through the heat exchanger 103 is the maximum temperature (t_max). The heating efficiency decreases and the time required for heating may increase because the heating efficiency becomes lower than that (for example, 50°C, etc.). In order to reduce the heating time, the heating supply temperature must be increased. To this end, the hot water line 110 Although it is possible to increase the heating supply temperature by increasing the flow rate of hot water in the water, there is a limitation that it is difficult to increase it above the hot water temperature.

In addition, when facility piping such as a hot water supply line and a household heat source supply line is expanded to increase the flow rate, and the capacity of the heat source supply pump is increased, not only the facility cost increases, but also the heating efficiency still decreases, resulting in an increase in the household heating cost.

In the present invention, in order to improve the heating performance, the hot water supply heat source is mixed with the water supply 102 through the first mixer 200 even when the temperature of the hot water supply heat source is increased to 65° C. or higher, which exceeds the maximum temperature (t_max). Since it is possible to tap water by limiting the temperature to be tapped by the hot water supply 101 to 55°C or less, it is possible to prevent burn hazards in advance and to efficiently induce an increase in the temperature of the heating water from an elevated hot water source (65°C or higher).

The hot water supply heating integrated piping system 100 using a hot water supply line as a heat source according to an embodiment of the present invention has the advantage of relatively simply improving heating performance without adding or expanding facilities such as pump performance and pipe diameter size.

The hot water supply heating integrated piping system 100 using the hot water supply line as a heat source according to an embodiment of the present invention has the advantage of supplying heating water at a heating temperature higher than the required burn protection temperature while supplying the hot water temperature at a temperature below the burn protection temperature. There is this.

The hot water supply heating integrated piping system 100 using a hot water supply line as a heat source according to an embodiment of the present invention has an advantageous advantage of being able to freely supply heating and hot water as much as necessary heat quantity.
