Description

Solar floor heating system

technical field

The utility model relates to a solar energy utilization device, which belongs to the field of light and heat utilization of solar energy. the

Background technique

Solar floor radiant heating, referred to as solar floor heating, is a system that uses collected solar energy as a heat source to heat the ground through coils laid in the floor. It is a combination of solar energy as a heat source and floor heating. As we all know, solar energy is an inexhaustible source of energy. The country is promoting a conservation-oriented society, and energy conservation is the most important topic today. Therefore, solar radiant floor heating is more and more subject to people's attention. So far, solar thermal utilization is still the most cost-effective way of utilizing new energy. Today, solar thermal utilization is mainly used for heating water in buildings to meet people's living needs. In recent years, some solar photothermal utilization systems for building heating have been developed, using a single working medium and sharing a water tank with the solar collector. The heating water is mixed with the working medium in the solar collector, which causes inconvenience for heating in winter. The system is practical Poor sex. the

Underfloor heating is to store heat in the floor and transfer heat to the room through floor radiation and air convection. The combination of floor heating and solar thermal can reduce the capacity of solar water storage tank, so floor heating is a good end of solar heating. the

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and invent a fully automatic solar floor heating system. the

The working medium of the solar collector is antifreeze, and the heat storage working medium tank is a non-pressurized water tank. the

The solar cycle of the utility model adopts a fully automatic cycle mode, the circulating working medium is heated by the solar collector array, and the circulating power of the working medium in the solar collector is provided by the solar circulating pump, and the solar circulating pump is started when the temperature reaches T1, and the antifreeze is supplied by the solar energy The lower part of the collector array goes out and enters the plate heat exchanger, through which heat is exchanged to heat the water in the water tank which is circulating at the same time. The heated water returns to the water tank. When the water in the water tank is heated to T2 in this way, the floor heating circulating pump starts, and the circulating working medium comes out from the lower part of the hot water storage tank, passes the heat to the floor through the floor heating coil, and returns to the The upper part of the hot water storage tank. the

Both the solar circulation system and the floor heating system of the utility model are normal pressure systems, and the heat storage medium tank is a non-pressurized water tank, so that the reliability of the system can be improved and the system cost can be reduced. the

The working substance in the solar cycle system of the utility model is antifreeze, so that it can still operate normally at low temperature in winter without being affected by the cold temperature. the

The advantage of the utility model is that the solar circulation system and the floor heating system are relatively independent water tanks, and the respective working fluids are separated, and they are connected with each other through a plate heat exchanger, which can avoid fouling and corrosion of the solar heat collector, and delay the heating process. service life. the
