Pyroelectricity recovery device for waste heat energy of air conditioner

Abstract

The invention relates to a pyroelectricity recovery device for waste heat energy of an air conditioner. The device comprises a condensate water collecting and distributing device with a metal porous medium, a semiconductor temperature difference generator and an electricity storage, wherein a condensate water tube of the air conditioner is inserted into the inlet of the condensate water collectingand distributing device with the metal porous medium; an upper pipeline of the condensate water collecting and distributing device with the metal porous medium collects condensate water imported to the air conditioner; a plurality of water dividing pipes are arranged on the lower part of the condensate water collecting and distributing device to convey the collected condensate water uniformly toa metal porous dielectric layer; the cold face of the semiconductor temperature difference generator is tightly attached to the metal porous dielectric surface filled by condensate water; and the heatend surface of the semiconductor temperature difference generator is arranged near to the hot air blowing side of an outdoor unit of the air conditioner, and the cold end and the hot end of a semiconductor material are separately connected to an energy storage device. The device provided by the invention recovers waste heat energy of an air conditioner system by means of a semiconductor temperature difference generating technology, and purposes of being energy-saving and reducing heat pollution by adding an independent simple device on the basis of not wasting other energy sources and affecting applications of the original air conditioner refrigerating system.

Description

technical field [0001] The invention relates to the technical field of semiconductor thermoelectric power generation, and more specifically relates to a novel air-conditioning waste heat recovery system. Background technique [0002] Air conditioners are the main refrigeration equipment in most homes, shopping malls, companies and other occasions. However, a large part of the heat energy generated by the air conditioner during use and the energy in the condensed water are wasted. According to statistics, the energy consumption of building heating and air conditioning in my country is higher than that of developed countries, and the energy consumption per unit area of ​​cooling is equivalent to 2-3 times that of developed countries with similar climates. Seasonal power shortages occur during peak power consumption in summer, resulting in "power shortage". From the principle of air conditioning, we know that in summer, when the supply air temperature of the air conditioner is...

Problems solved by technology

The harsh heat dissipation conditions make the heat dissipation capacity of the air-cooled condenser of the household air conditioner (that is, the outdoor unit of the air conditioner) less and less able to meet the factory design requirements of the air conditioner (the design temperature of the outdoor air conditioner in general is 35°C in summer, and the average summer temperature is generally 38°C today. left and right, the heat dissipation area and ventilation volume of the outdoor unit of the air conditioner are obviously small), and the poor heat dissipation conditions reduce the working capacity of the outdoor unit of the air conditioner and increase the cooling energy consumption of the air conditioner
