Solar semiconductor air conditioning umbrella based on thermoelectric refrigeration and direct evaporation refrigeration

Abstract

The invention belongs to the related technical field of solar energy conversion and utilization equipment, The invention discloses a solar semiconductor air conditioning umbrella based on thermoelectric refrigeration and direct evaporation refrigeration. The air conditioning umbrella comprises a base, a plurality of pulleys, an umbrella rod, an air outlet pipe, a refrigeration assembly and an umbrella surface. The umbrella rod is vertically arranged, one end of the umbrella rod is connected with one side of the base, and the other end of the umbrella rod is connected with the umbrella surface;The refrigeration assembly is arranged in the base, and is used for refrigerating the air and transmitting the cooled and humidified air to the air outlet pipe. One end of the air outlet pipe is connected with the base, and is positioned directly below the umbrella surface; The air outlet pipe is used for ejecting the air after the cooling and humidification, and the air outlet direction and thewind speed are adjusted by 360 DEG by rotation to meet the cooling in the predetermined space of the umbrella surface. The invention improves the refrigeration effect, has strong practicability, and is energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the related technical field of solar energy conversion and utilization equipment, and more specifically relates to a solar semiconductor air-conditioning umbrella based on thermoelectric refrigeration and direct evaporative refrigeration. Background technique [0002] With the arrival of summer, energy consumption will usher in a peak period. At the same time, due to the work position, outdoor workers such as traffic police at intersections have to perform high-intensity work in summer, which can easily cause adverse reactions such as heatstroke and dehydration. The combination of global warming, urban heat island effect and other related factors makes high temperature more likely to become the norm in summer, which affects the comfort of people's outdoor activities and work. [0003] At present, the improvement of sun umbrellas at home and abroad mainly focuses on the appearance and structure, which can reduce direct sunlight...

Problems solved by technology

At this stage, those skilled in the art have done some research. For example, patent CN107874395A discloses an air-conditioning umbrella using solar cells as a power source. Water spraying devices are added on the umbrella surface, which can produce mist-like umbrellas in high-temperature environments. The cold wind blows to the face and the whole body of the umbrella holder, absorbs most of the heat generated by the heat and makes people feel extremely cool, which solves the problem of summer heat. The disadvantage is that the water spray pipe is close to the umbrella surface, making the umbrella The surface absorbs solar heat and transfers it to the water, which then increases the water temperature, greatly reducing the cooling effect, and even spraying water mist after a long time is high-temperature water vapor; secondly, spraying water mist will reduce the comfort of the human body, and the design consumes a lot of water. , high water quality requirements

Another example is patent CN101435611A, which discloses a solar air-conditioning umbrella using semiconductor refrigeration. A semiconductor module is installed in the hollow umbrella top pillar, and the cooling capacity is taken out by fan blowing fins to achieve the purpose of air conditioning regulation. The device structure is simple and stable. The disadvantage is that the cooling capacity and cooling efficiency of semiconductor refrigeration are low, the effect of cooling air is poor, and the power consumption is large; in addition, the designed cold air outlet makes part of the cold air go upward along the umbrella pillar, and the other A part of the cold air goes down the umbrella pillars, which cannot achieve the effect of cooling the people under the umbrella
