Air source heat pump defrosting and deashing device and method based on shock wave and heat pipe technologies

Abstract

The invention provides an air source heat pump defrosting and deashing device and method based on shock wave and heat pipe technologies. A heat pipe set is arranged in an outdoor heat pipe heat exchanger, an inductor and an air shock wave generator are arranged on the outdoor heat pipe heat exchanger, and the air shock wave generator and the inductor are connected with a controller through USB cables correspondingly. A steam channel is arranged in a heat pipe of the heat pipe set, a liquid absorbing pipe core is arranged on the inner side of a pipe wall, and a fixed support and heat exchanging fins are arranged outside the pipe wall; one end of the heat pipe set communicates into a combined collection pipe, and an intermediate bulkhead or a baffle plate is arranged on the heat pipe set. The method comprises the following steps that (1), parameters are set; (2), a cooling mode is conducted; and (3), a heating mode is conducted. According to the air source heat pump defrosting and deashing device and method based on the shock wave and heat pipe technologies, traditional chemical modes of manual cleansing and defrosting through heating are replaced with a shock wave mode, pollution cannot be generated on a water source and air, and the phenomena that the indoor temperature is lowered, or heating is stopped, and electric energy is wasted caused by defrosting, so that operating efficiency of a heat pump is lowered are avoided; and operational cost is low, the service life is long, operation is easy, control, overhaul and maintenance are convenient, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the field of shock waves and air source heat pumps, in particular to an air source heat pump defrosting and dust removal device and method based on shock wave and heat pipe technology. Background technique [0002] At present, the air source heat pump system has already entered thousands of households due to its advantages of energy saving, environmental protection, intelligent control, year-round heating and cooling supply, and convenient installation, far exceeding the application of solar energy and geothermal energy and other technologies. During the long-term use of the air source heat pump outdoor unit, a large amount of dust will accumulate on the surface of the heat exchanger in summer, which will affect the heat exchange efficiency. In addition, the application of air source heat pump products is also limited by climatic conditions, especially in cold regions and the south In humid areas, when the air source heat pump ...

AI Technical Summary

Problems solved by technology

During the long-term use of the air source heat pump outdoor unit, a large amount of dust will accumulate on the surface of the heat exchanger in summer, which will affect the heat exchange efficiency. In addition, the application of air source heat pump products is also limited by climatic conditions, especially in cold regions and the south In humid areas, when the air source heat pump system is running in winter, when the surface temperature of the outdoor heat exchanger is lower than the dew point temperature of the surrounding air and lower than 0°C, frost will form on the surface of the heat exchanger, and the formation of frost will have a negative impact on the heat pump. The performance of the heat exchanger has adverse effects, such as blocking the passage between the fins, increasing the resistance of air flow; increasing the surface heat transfer resistance, deteriorating the heat transfer effect of the heat exchanger, reducing the heat transfer capacity, and even stopping the heat pump system in severe cases run

[0003] The existing defrosting methods of air source heat pumps usually include: hot gas defrosting method, electric heating defrosting method, hot water defrosting method, etc. Their common feature is that the indoor temperature will drop or stop heating during the defrosting process, which wastes Electric energy, causing the heat pump to operate less efficiently

At present, chemical cleaning is mainly used to remove dust from outdoor heat exchangers. The disadvantage of this method is that it will pollute the water source and air, and cause corrosion and other hazards to the equipment.
