Description

Technical Field

[0001] The utility model relates to the technical field of building heating, and in particular to an energy-saving hut based on phase change heat storage heating. Background Art

[0002] Solar energy has gradually become an important substitute for fossil energy due to its wide distribution, easy access, large energy reserves, and cleanliness and pollution-free. The comprehensive utilization of solar energy is one of the effective ways to solve energy and environmental pollution problems.

[0003] However, due to the intermittent, unstable and periodic characteristics of solar energy, it is difficult for traditional solar heating systems to meet the 24-hour "all-weather" needs of heating users. In order to meet user needs, current market heating projects usually use electric heating, gas, and air source heat pumps as auxiliary heat sources based on traditional conventional solar heating systems. There are mainly solar energy and electric heating, gas, and air source heat pump multi-energy device operation modes. The system is more complex and has poor operating economy. The heating system generally uses water as the heat storage medium, which uses the increase in water temperature to store heat, so the heat storage capacity is very low. In order to store more heat, the water tank is often designed to be larger, which is not convenient for the installation and use of solar energy; and as the water temperature increases, it loses more heat, which is not conducive to the long-term preservation and utilization of heat, and the heat storage capacity is limited and occupies a large area. Utility Model Content

[0004] The purpose of the utility model is to provide an energy-saving hut based on phase change heat storage heating, which has heat storage capacity. The heating units are arranged up and down in the heat storage unit, part of the heat of the upper heating unit is directly transferred to the room, so that the indoor temperature rises quickly, and part of the heat is stored in the heat storage unit, and the heat of the lower heating unit is all stored in the heat storage unit, thereby realizing all-weather heating of the heating system and occupying a small area.

[0005] The utility model is realized by the following technical solutions:

[0007] Among them, the heat-generating heat storage layer includes a heat storage unit and a heat-generating unit, the heat-generating unit is a circular structure and is evenly arrayed along the heat storage unit, the auxiliary energy system supplies energy to the heat-generating unit, one side of the heat-generating unit is located on the upper surface of the heat storage unit, and the other side of the heat-generating unit is located on the lower surface of the heat storage unit.

[0008] In this solution, when the auxiliary energy system has sufficient electric energy, the auxiliary energy can be directly used to power the heating unit to generate heat, and the heat is stored through the heat storage unit, wherein the heating units are arranged up and down in the heat storage unit, part of the heat of the upper heating unit is directly transferred to the room, so that the room temperature rises rapidly, and part of the heat is stored in the heat storage unit, and the heat of the lower heating unit is all stored in the heat storage unit, so as to achieve better energy conversion rate while heating rapidly, and the heat storage unit is used to heat the room at night.

[0012] As a further technical solution for the energy-saving cabin, the ground structure also includes a steel keel and a base steel plate. The steel keel is a frame structure and is laid on the foundation. The base steel plate is arranged between the insulation layer and the steel keel. By arranging the heat storage unit and the heating unit on the steel keel, the steel keel is formed into an assembled module, thereby simplifying the installation process.
