Adjustable phase change heat storage floor based on heat storage heating pipes

Abstract

The invention discloses an adjustable phase change heat storage floor based on heat storage heating pipes. The adjustable phase change heat storage floor comprises a structural layer, a damp-roof layer, a thermal insulating layer, a packing layer and a decoration surface layer. A plurality of heating pipe modules are laid in the packing layer, connected in parallel in an equal pipe road mode, and arranged between a water distributing device and a water collecting device located on the two sides of a room. A water inlet of each heating pipe module is connected to the water distributing device through a water supply pipe of the module. A water outlet of each heating pipe module is connected to the water collecting device through a water return pipe of the module. Each heating pipe module is a loop composed of the multiple heat storage heating pipes connected in series. The packing layer is further internally provided with heat storage bars. By adoption of the adjustable phase change heat storage floor, efficient and diversified utilization of solar energy in building heating in winter can be achieved, and the problem that coal-fired heating is adopted in rural areas in northern China and the environment is polluted is relieved; and meanwhile, the problem of peak power shortage can be solved, peak-load shifting is achieved, and development of coal-to-electricity projects is facilitated.

Description

technical field [0001] The invention relates to the technical field of building energy saving and new energy utilization, in particular to an adjustable phase-change heat storage floor based on heat storage heating pipes. Background technique [0002] At present, the main energy sources in the world are coal, oil and natural gas. Oil and gas resources will be exhausted by 2050. With the development of the economy, the world's primary energy consumption continues to increase, and coal is the fastest growing fossil fuel in the world. It is well known that the use of fossil fuels results in a large amount of carbon emissions and disrupts the ecological balance. China's energy supply mainly depends on coal, which accounts for 76% of all energy consumption. At present, my country's energy utilization technology is backward and inefficient, and a large amount of coal is consumed in direct combustion, which causes air pollution and directly endangers people's health. It is imper...

Problems solved by technology

There have been a lot of researches on the phase change heat storage floor. There are many ways to combine the floor radiant heating pipe and the phase change material. The outer wall of the floor radiant heating pipe and the phase change material are in indirect contact, and the heat transfer effect is not good. The use of phase change material The heat supply rate of the floor system is low, and the heat supply of the floor system cannot be adjusted according to the heat load. It is easy to cause a large amount of heat supply at the beginning and end of the heating period, and the room temperature is too high. When the heat load is large, the room temperature may not be guaranteed.
