A waste heat collection system for collecting air conditioner waste heat

Abstract

The invention provides an air conditioner waste heat collecting system. An air conditioner comprises an air conditioner outdoor unit shell, wherein the air conditioner outdoor unit shell is provided with an air outlet face mask; the air conditioner waste heat collecting system comprises a fairing and an energy conversion device; the fairing is provided with a first end part and a second end part extending in different directions; the first end part is fixed at the air conditioner outdoor unit shell; the second end part is provided with an air outlet; the fairing body is structured to guide hot-blast air flow discharged out of the air outlet face mask to the air outlet; and the energy conversion device is arranged at the air outlet and is used for collecting waste heat energy of the hot-blast air flow, converting the waste heat energy into electric energy, and outputting an electric signal outwards through an external circuit. According to the scheme, the air conditioner waste heat collecting system is arranged to collect the heat energy and wind energy of the hot-blast air flow discharged out of the air outlet face mask and convert the heat energy and wind energy into electric energy, so that waste heat reutilization is realized, and climate warming and discomfortableness to people caused by discharge of waste heat are also avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioner waste heat reuse, in particular to a waste heat collection system for collecting air conditioner waste heat. Background technique [0002] With the drastic changes in weather and people's demand for a comfortable home environment, air conditioners have become one of the essential household appliances in life, but their power consumption is huge. When the air conditioner is cooling in summer, the external unit of the air conditioner will discharge hot air with a certain temperature at the same time. While bringing comfort to people, it also aggravates problems such as energy consumption and global warming. Therefore, in combination with the energy saving and emission reduction requirements in the air conditioning field and the working characteristics of the Stirling machine, it is a blank area in the current energy saving and emission reduction technology field and the air conditioning mar...

Problems solved by technology

[0003] According to research and investigation, the invention patent with the patent number 201310145741.4 discloses an air-conditioning energy-saving device and its application based on Stirling machine and condensed water reuse technology. The device includes a condensed water reuse device and a Stirling energy-saving device. A Stirling machine utilizes the heat of the copper tube at the outlet of the air conditioner compressor, and the condensed water distribution plate utilizes the waste cold generated by the air conditioner to achieve the purpose of energy saving, but its device ignores the kinetic energy of the exhaust air of the external unit. The energy carried by the exhaust itself is very high, and it would be a waste of energy if it is not utilized; in addition, the Chinese patent application number 201410598883.0 discloses an air conditioner with waste heat recovery function, which uses a thermoelectric device to The waste heat emitted by the air conditioner is recovered by the thermoelectric device for internal use of the air conditioner. Because the temperature difference is not large, the efficiency of waste heat utilization has not been significantly improved.
