The outer heat insulating system with sprayed water foamed polyurethane includes a moistureproof interface layer, a heat insulating polyurethane layer, an interface layer, a light protecting mortar layer and a flexible putty layer covered to the surface of outer wall successively. The light protecting mortar layer has sandwiched netted fabric, and the corner of the outer heat insulating system is provided with corner guard. The heat insulating polyurethane layer has polyurethane foamed with water, rather than Freon, as foaming agent and high heat insulating performance, and is environment friendly.

The invention discloses a building outer wall structure with double shaping phase change material layers. The building outer wall structure sequentially comprises the outer shaping phase change wall board layer, a first thermal insulation layer, a wall body layer, a second thermal insulation layer, the inner shaping phase change wall board layer from outside to inside, wherein the outer shaping phase change wall board layer and the inner shaping phase change wall board layer are respectively made of phase change materials of phase change temperatures of Tm1 and Tm2, the phase change temperature Tm1 is set to be minimum in cold load all year round in the expositing environment of the phase change temperature Tm1, and the solid phase change materials melt into liquid phase change materials when the wall board layer temperature is equal to or higher than Tm1; the phase change temperature Tm2 is set to be minimum in heat load all year round in the exposing environment of the phase change temperature Tm2, and the solid phase change materials melt into liquid phase change materials when the wall board layer temperature is equal to or higher than Tm2. The invention further designs the components and proportion of the phase change materials of the two shaping phase change wall board layers. By the building outer wall structure which is compact, high in adaptability, convenient to manufacture and maintain later, and the like, outer wall cold load and heat load can be lowered effectively, and overall energy consumption is lowered evidently.

The application discloses a refrigeration unit for transportation, a door curtain of the refrigeration unit and a refrigerator car. The door curtain comprises a curtain body and a track. The curtain body is movably installed on the track, and the track is provided with a main section where the curtain body moves into a door area to be insulated from the outside and an extending section guiding thecurtain body to move out of the door area. The door curtain is a movable door curtain which can move relative to the door.

The invention discloses a floor radiation air-conditioning system based on latent heat transfer fluid. The first medium is fluid, and the first medium is filled in the heat exchange tube; the second medium is filled outside the heat exchange tube, and the second medium exchanges heat with the external environment. ; The first medium includes the first phase-change material and the second phase-change material, the second medium includes the third phase-change material, the phase-change temperature range of the first phase-change material is denoted as [a, b], and the second phase-change material The phase transition temperature range of is denoted as [c,d], and the phase transition temperature range of the third phase transition material is denoted as [m,n], satisfying n≥d>a≥m. Beneficial effects: the third phase change material has good heat storage performance, can play a good buffering role on the indoor temperature, and is beneficial to reducing indoor temperature fluctuations and reducing overall energy consumption. The technical solution realizes the integration of refrigeration and heating by sharing heat exchange tubes, which is beneficial to saving space. The present invention relates to air conditioning systems.

The embodiments of the invention disclose a window shutter for adjusting temperature and a preparation method of the window shutter. The window shutter includes a plurality of fixedly connected blades, wherein the blades are filled with composite shaped phase change materials made of organic phase change materials and inorganic support materials. The preparation method comprises the step of a process of filling the composite shaped phase change materials made of the organic phase change materials and the inorganic support materials into the blades. According to composite phase change energy storage materials, the preparation technology is simple, the operation is convenient, requirements on operators are low, and the manpower cost and raw material cost can be saved.

The invention relates to phase-change roof self-insulation ceramsite concrete, and belongs to the technical field of building materials. The problems that existing ceramsite concrete is low in strength property and poor in energy storage effect can be solved. The phase-change roof self-insulation ceramsite concrete comprises, by mass, 30%-40% of cement, 20%-35% of pottery sand, 8.0%-13% of phase-change material, 10%-20% of ceramsite and 5.0%-8.0% of coal ash. The phase-change material uses the ceramsite as a loaded carrier. According to the concrete, the phase-change material is added and loaded onto the ceramsite, hence, a good energy storage effect can be achieved, and a large amount of heat can be stored or released when phase change happens; the phase-change latent heat range is wide, indoor temperature fluctuation is reduced, and cost is lowered; meanwhile, the strength property of the concrete can be guaranteed.
