Underfloor heating system of solar hot water heat supply

Abstract

The invention relates to the field of underfloor heating heat supply, in particular to an underfloor heating system of solar hot water heat supply. The underfloor heating system comprises a solar thermal collector, an auxiliary heating system, a heating base plate, a hot water pipeline, a water konckout vessel, a water collector and an intelligent control system, wherein the heating base plate is paved on a cement floor; the hot water pipeline is embedded in the heating base plate; a hot water discharging end of the solar thermal collector is connected with the auxiliary heating system; a hot water discharging end of the auxiliary heating system is connected with the hot water pipeline through the water konckout vessel; a water returning end of the hot water pipeline is connected with a water returning end of the auxiliary heating system through the water collector; and an external cold water source is connected with a cold water inlet end of the auxiliary heating system and a cold water inlet end of the solar thermal collector through manually operated valves or electromagnetic valves. The underfloor heating system adopts the renewable energy solar energy, saves more energy and reduces emission, is faster in heating, does not need plenty of heat, reduces storey height of underfloor heating, is suitable for underfloor heating transformation of existing old buildings without affecting the original storey height, and can save plenty of heat energy of a heat supply company to reduce carbon emission.

Description

technical field [0001] The invention relates to the field of floor heating and heating, in particular to a floor heating system for solar hot water heating. Background technique [0002] Traditional ground heating and hot water pipelines are buried under a 7-12cm thick cement cushion, which consumes a lot of heat, wastes building materials, increases the load bearing of the building, and only central heating can realize heating. The newly developed floor heating heating method uses solar collectors as the heat source, and the hot water is heated through the polybutene (PB) pipeline embedded in the heating substrate, and then evenly heats the surface wooden floor or floor tiles, using the heat storage of the ground itself And the heat radiates upwards and conducts from bottom to top to achieve the purpose of heating. The low-temperature ground heat forms a gradually decreasing temperature gradient from the soles of the feet to the head indoors, thus giving people a comfortab...
