Other embodiments

The intelligent refrigeration house is used for freezing beef and mutton, the photovoltaic module is provided with 14 solar cell panels with the inclination angle of 40-45 degrees and the length of 2m x 1m (width), an upper layer and a lower layer of solar cell panels with the interval of 0.4m are arranged outside the side wall structure of the refrigeration house, 7 solar cell panels are vertically arranged on the lower layer, 3 solar cell panels are transversely arranged on the upper layer, and 4 solar cell panels with the interval of 1m are arranged on the top. The generated power of each solar panel is 300w, the sunshine time is 6 hours, and the electric energy Q =300w/1000 x 6h x 14=25.2kw · h generated by the photovoltaic module in a sunny day.

And arranging 3 windmills with the height of 2m and the generating power of 400w at the top of the refrigeration house, wherein the interval between every two windmills is 1m, and the base size of the bottom is 1m by 1 m. The wind power generation device generates electric energy Q =400w/1000 h 6h 3 =7.2kw · h per day.

The generator, the controller, the storage battery, the refrigerator outdoor unit and the like are positioned below the top solar panel, and an anti-corrosion protection device is arranged. The controller supplies the electric quantity generated by the wind power generation device and the photovoltaic power generation device to the direct current compressor of the refrigeration house, and when the capacity is higher than the load required by the refrigeration house, the controller adjusts the electric quantity to be transmitted to the storage battery for storage.

The refrigerator with the external dimension of 7m 3m 2.5m (length, width, height) is divided into two freezing chambers with the external dimension of 3.5m 3m 2.5m (length, width, height) and the freezing temperature of-18 to-20 ℃ and the external dimension of 3.5m 3m 2.5m (length, width, height) and the freezing temperature of-12 to-14 ℃. The afternoon illumination is stronger than the morning illumination, the morning sun is located at the east side, and the afternoon sun is located at the west side, so that the east freezing chamber is set to be lower in temperature from-18 ℃ to-20 ℃ for freezing the beef, and the west freezing chamber is set to be higher in temperature from-12 ℃ to-14 ℃ for freezing the mutton. And the clapboards are arranged at the inner sides and the middle parts of the east side wall and the west side wall of the side wall refrigeration house, thereby reducing the convection loss of cold air and being beneficial to the circulation and circulation of the cold air. When the cold storage amount is not considered, the power consumption of the mutton freezing chamber is 7.6 kw.h per day, the power consumption of the beef freezing chamber is 7.9 kw.h per day, and the total power consumption of the refrigerator is 15.5 kw.h per day.

Two pieces with a size of 3.0m x 1m x 0.02m (length x width x height) were placed

The cold storage plate is arranged at the included angle between the inner side walls of the south side wall and the north side wall of the beef freezing chamber top and the ceiling, and the size of the cold storage plate is 2.8m by 2.3m by 0.02m

The cold accumulation plate is arranged on the inner surface of the east and west side walls of the beef freezing chamber. Because the solar panel is arranged outside the south side wall, the heat transfer quantity of the direct radiation of the sun to the side wall refrigeration house is weakened, and meanwhile, the north side wall is a backlight surface, so that less cold storage plates are only arranged inside the south and north side walls of the refrigeration house, and because the density of cold air is high, the cold air is easy to circulate downwards, the cold storage plates are arranged on the upper part, and the uniform distribution of the cold air is facilitated. The side wall of the freezing chamber has direct sunlight, so the whole side wall is provided with the cold storage plate, but the thickness of the cold storage plate is thinner.

Two blocks of size 3.0m 1m 0.02m (length width height)

The cold storage plates are arranged at the included angle between the north and south side walls and the ceiling at the top of the mutton freezing chamber, and the size of the cold storage plates is 2.8m by 2.3m by 0.02m

The cold accumulation plate is arranged on the inner surface of the east and west side walls of the mutton freezing chamber. Because the south lateral wall is provided with the panel outward, has weakened because the solar radiation effect passes through the heat transfer capacity of this direction lateral wall, and the north lateral wall is the backlight face simultaneously, and the heat sees through less, consequently only sets up less cold-storage plate in freezer north-south direction lateral wall inside to because the density of cold air is big, the easy downward circulation, consequently will be as above the cold-storage plate set up in the top, be favorable to the downstream of cold air. The west side wall of the freezing chamber has direct sunlight, so the whole side wall is provided with the cold storage plate, but the thickness of the cold storage plate is thinner.

The cold accumulation plate absorbs redundant cold accumulation when the cold accumulation is released to the interior of the refrigeration house by the refrigeration house compressor. When no wind and no sun exist, the cold storage plate releases the stored cold energy to maintain the low temperature of the freezing space.

Two direct current fan are located mutton freezer and beef freezer top intermediate position respectively, absorb the relatively higher hot air that rises of freezer central zone temperature through the direct current fan that the opening is decurrent, then blow out through the wind gap of fan north and south both sides, and the gaseous circulation flow makes the temperature distribution in freezing space more even, has improved the frozen product quality. When the direct current fan works, when wind energy and solar energy are generated, the wind energy and the solar energy are used for supplying power, when no wind energy and no solar energy are generated, the storage battery is used for supplying power, and when no capacity and no energy is stored, the direct current fan can be switched to the commercial power.

The embodiment of the present invention discloses a preferred embodiment, but not limited thereto, and those skilled in the art can easily understand the spirit of the present invention according to the above embodiment, and make different extensions and changes, but do not depart from the spirit of the present invention, all of which are within the protection scope of the present invention.
