Description

Hot water and heat control system using sun heat}

The present invention relates to a heating system using solar heat, and forcibly converts hot water by heat stored by solar heat and heat generated by discount electricity at midnight during the day to the boiler side and heat-exchanges the heating water inside the boiler to the same amount of heat. The present invention relates to a hot water / heat control system using solar heat configured to enable more hot water for boiler operation.

In general, as a heating system, a boiler using fossil fuel such as oil or gas is used. Therefore, in the case of a boiler using fossil fuel, any fuel is combusted to heat water or air with thermal energy generated during the combustion process, and then the heated water or air is transferred to any space to be heated to heat the corresponding space. It can be divided into industrial and household.

At this time, in the heating system using fossil fuel, a large part of the pollutants are discharged due to incomplete combustion during the combustion of the fuel, and the reserves of the fuel are limited due to the characteristics of the fossil fuel. As a result, development of various alternative fuels or alternative energies is being actively promoted.

Among various technologies proposed by the development of alternative energy as described above, a technology using solar heat, which can be called infinite energy, has been commercialized, and a heating system using such solar energy is mostly developed for home use.

The reason is that due to the technical limitations of accumulating solar heat as electric energy or other energy for industrial applications requiring large amounts of energy, the current technology is commercialized in a complementary manner of home heating. Conventional forced circulation solar system is a system that exchanges heat by forcibly circulating heat when the solar energy collected from the collector is stored in the heat storage tank.It is more efficient than the natural convection type and can prevent freezing of the heat storage pipe and restricts the installation location.

In the case of heating control valve 550 control setting, if T3 is 44.0 or less or T5 is 15.0 or more than T3, the heating switching valve 550 is controlled in the 1-> 3 direction, otherwise T3> T5 and T3> If 45.0, the heating switching valve 550 is controlled in the 1-> 2 direction.

At this time, the heat of the heat exchanger 300 side is transferred to the heat storage tank 400 side, the heat medium is lowered in this process via the heat medium storage tank 300 to the heat collecting plate 200 again by the heat medium circulation pump 230. The transfer process is repeated. On the other hand, the low-temperature water supplied through the heat storage tank 400 is introduced into the heat exchanger 300 side to repeat the process of storing the heat received by heat exchange in the heat storage tank 400.

In this process, when solar heat is absorbed by the heat collecting plate 200, the temperature T1 of the heat collecting plate 200 is measured by the first temperature measuring device installed on the heat collecting plate 200, and the third, 4 The temperature T3 and T4 of the heat storage tank are measured by the temperature measuring device, and the temperature T2 of the heat medium storage tank 300 is measured by the second temperature measuring device installed on the heat medium storage tank 300 side. The measured temperature values T1 to T4 are transmitted to the controller 600.

At this time, since the temperature of the heat medium storage tank 300 and the temperature of the heat exchanger 400 is not significantly different, it is installed in the heat exchanger 400 or a pipe between the heat medium storage tank 300 and the heat exchanger 400. It can also be installed in.

On the other hand, if T5 has a temperature difference of more than the set temperature (20 degrees) than T3 in the two-step control operation, it is preferable to recognize that the boiler is operating and to switch back to the HV (1-> 3) valve.

In this case, if the boiler hot water setting is set to medium temperature water, the boiler room and the solar thermal storage tank are used simultaneously, and if the hot water setting of the boiler is set to medium temperature water, the mixed type of heating the solar heat source and the secondary heat boiler firstly. To use.

And, in the case of solar alone operation that turns off the boiler and heats only solar heat, the heat medium pump has a certain period of rest and is started.

It consists of a heat sink installed in an oblique direction and absorbing solar heat, a heat storage chamber for storing solar heat absorbed by the heat collecting plate, and a boiler system installed in an existing hot water supply system. In the solar hot water / heat control system having a control unit for use,  A plurality of temperature measuring devices are installed in the heat collecting plate, the heat storage chamber, and the boiler room, and when the heat storage tank upper temperature T3 constituting the heat storage chamber measured by the measuring device is lower than the control set temperature, HV (1-> 3). One-step control is executed to switch the valve to use in boiler only mode, When the heat storage tank upper temperature (T3) is above a predetermined temperature, by switching the HV (1-> 2) valve to enable the two-step control to control the heating to use only the heat storage temperature, and during the two-step control operation If the heating hot water return temperature (T6) is higher than the heat storage tank upper temperature (T3) is recognized as a boiler operating state to be switched back to the HV (1-> 3) valve, If T5 has a temperature difference of more than a set temperature (20 degrees) above the heat storage tank upper temperature (T3) in the two-stage control operation, the boiler is recognized as operating and switched back to the HV (1-> 3) valve. , In the case of solar alone operation in which the boiler is turned off and only the solar heat is heated, when the heat medium pump has a certain period of rest and is started, the temperature difference between the heat collector plate temperature (T1) and the heat medium storage tank temperature (T2) is a set temperature (30 degrees). If heat occurs above), the heat medium pipe is preheated, so that the heat medium pipe preheating function is not allowed to be wasted. When the heat storage tank upper temperature (T3) reaches a temperature capable of heating, power is applied to the solar room cone to inform the user of the possibility of solar heating, and the user can control the room temperature using the solar room cone, but the solar room cone and 'S communication is based on the solar system, which can be installed without any construction in the main building by using a wire system using a separate line and using power line communication (PLC) using existing AC 220 power. Hot water / heat control system.
