The heat storage materials 33 can be classified into four types: sensible heat storage material, phase change heat storage material, thermochemical heat storage material, and adsorption heat storage material.

1. Sensible heat storage material

The sensible heat storage material stores heat by utilizing the temperature change process of the substance, and the sensible heat storage material can adopt direct contact heat exchange or fluid is a heat storage medium, so that the heat storage and release processes are relatively simple, and the sensible heat storage material is a heat storage material with more early application. The sensible heat storage technology is the simplest and mature in all heat storage materials.

Most of the sensible heat storage materials can be directly obtained from the natural world, and are low in cost and easy to obtain. Sensible heat storage materials are classified into two types, liquid and solid, liquid materials are commonly used such as water, solid materials such as rock, cobble, soil, etc., and several sensible heat storage materials are attracting attention such as mixed materials formed by sintering Li2O with Al2O3, tiO2, etc. at high temperature.

The sensible heat storage material stores heat by means of temperature change of the heat storage material, the heat release process cannot be constant in temperature, the heat storage density is small, the volume of the heat storage equipment is huge, the heat storage efficiency is low, heat loss can be caused by temperature difference with the surrounding environment, the heat cannot be stored for a long time, the large capacity is stored, and the further development of the sensible heat storage material is limited.

2. Phase change heat storage material

The phase change heat storage material stores and utilizes heat by utilizing phase change heat generated by a substance during phase change such as solidification/melting, condensation/vaporization, solidification/sublimation and the like.

Compared with sensible heat storage materials, the phase change heat storage materials have high heat storage density, and can emit a large amount of heat at constant temperature through phase change. Although the phase-change latent heat value of the gas-liquid and gas-solid conversion is larger than the latent heat of the liquid-solid conversion and the solid-solid conversion, the great volume change exists in the phase-change process, so that the phase-change latent heat value can be very difficult in engineering practical application. The latent heat storage can be divided into low temperature and high temperature according to the high phase transition temperature, and the low Wen Qianre heat storage is mainly used for waste heat recovery, solar energy storage and heating and air conditioning systems. The high-temperature phase-change heat storage material mainly comprises high-temperature molten salts, mixed salts, metals, alloys and the like, and is mainly used for aerospace and the like. Common latent heat storage materials are calcium chloride hexahydrate, sodium acetate trihydrate, organic alcohols, and the like.

The latent heat storage mode has the advantages of higher heat storage density (generally more than 200 kJ/kg), approximately isothermal heat storage and release process, easy control of the process and the like, so the phase change heat storage material is the main stream of the research and application of the current heat storage material.

3. Thermochemical heat storage material

The thermochemical heat storage materials mostly utilize reversible chemical reactions of metal hydrides and amides to store heat, and have high thermal reaction speed when catalysts are used and the temperature is high and the equilibrium state is far away. The experimental study of solar heat storage power generation by utilizing the reaction is carried out abroad, but the problems of tightness of a storage container and a system, corrosion of generated gas to materials and the like are required to be considered.

The thermochemical heat storage material has the advantages of high heat storage density, cleanness, no pollution and the like, but has complex reaction process, high technical difficulty, high requirement on equipment safety, large one-time investment and larger distance from practical engineering application.

4. Adsorption heat storage material

Adsorption refers to the process of adsorption or retention of an adsorbate by solid particles (i.e., adsorbents) when a fluid phase (gas or liquid containing one or more components) is contacted with solid particles having porosity. Due to the non-uniformity of the surface of the adsorbent solid, an energy conversion effect, called heat of adsorption, is generated along with the adsorption process. In the adsorption and desorption cycle, the grade and the service time of heat can be changed through the heat storage and release processes, and the purposes of refrigeration, heat supply, heat storage and the like are realized.

The adsorption heat storage is a novel heat storage technology, researches are carried out later, and heat is stored and converted by utilizing adsorption working medium to carry out heat effect which is accompanied in the adsorption/desorption cycle process. The heat storage density of the adsorption heat storage material can reach 800-1000 kJ/kg, and the adsorption heat storage material has the advantages of high heat storage density, no heat loss in the heat storage process and the like. The adsorption heat storage material is nontoxic and pollution-free, and is another research hot spot except the phase change heat storage material, but the adsorption heat storage material is usually a porous material, so that the heat and mass transfer performance is poor, the adsorption heat storage is complex, and the problem of important research solution is solved.

In this embodiment, referring to fig. 7, an evaporation tube 51 is disposed in the evaporator 5, and the evaporation tube 51 has a multi-bending and folding structure; the evaporation tank with the multi-bending folding structure can improve the heat conduction efficiency.

In this embodiment, the air outlet pipe 61 is provided with an air exhaust valve for controlling the air volume to be exhausted; the exhaust valve can control the air quantity of the cold air discharged outwards at any time.
