Phase-change material combined underground water heating floor

Abstract

The invention discloses a phase-change material combined underground water heating floor. The underground water heating floor comprises a floor base layer, a damp-proof layer, an insulation thermal-preservation layer, a phase-change material layer, a coiled tube, stone concrete and a ground decoration layer. The underground water heating floor is characterized in that the coiled tube is communicated with an underground water heating main tube which is connected with an underground water heat exchanger, a flow control valve is arranged at the communication position of the underground water heating main tube and the underground water heat exchanger, and the underground water heat exchanger is connected with an underground water feeding tube and an underground water return tube. The underground water heating floor is simple in structure, reasonable in design, energysaving and environmentally friendly, high in resource utilization rate and convenient to popularize and use.

Description

technical field [0001] The invention relates to building heating technology, in particular to an underground water heating floor combined with phase change materials. Background technique [0002] The full name of floor heating, low-temperature floor radiant heating, low-temperature radiant floor heating is to heat the floor to a surface temperature of 18 to 32°C through the heating pipe buried under the floor—the special pipe for floor heating or heating cable, and evenly radiate heat to the indoor floor Heating to achieve heating effect. Compared with the traditional heating method, it can be said to have the following advantages: 1. The heating method is adopted with uniform temperature distribution in the room. Since the entire floor dissipates heat evenly, the temperature difference in the room is extremely small. Moreover, the indoor temperature gradually decreases from bottom to top, and the ground temperature is higher than the temperature of the human respiratory s...

AI Technical Summary

Problems solved by technology

Although floor heating has so many benefits, the current heat source of floor heating is mainly electric heating or coal-fired heating, which consumes a lot of energy on the heat source

However, the current groundwater heating technology is becoming more and more popular, and its utilization is not sufficient. It is limited to traditional indoor heating, and the utilization rate at the heating end is not high.
