Internal descaling and external defrosting novel air conditioner applying ultrasonic oscillators

Abstract

The invention provides an internal descaling and external defrosting novel air conditioner applying ultrasonic oscillators. The internal descaling and external defrosting novel air conditioner comprises an outdoor unit and an indoor unit. The outdoor unit and the indoor unit are connected through a pipeline. The indoor unit comprises the indoor ultrasonic oscillators and an indoor heat exchanger, wherein the indoor ultrasonic oscillators are located around the indoor heat exchanger. The indoor heat exchanger is a shell and tube heat exchanger and comprises fins, U-shaped pipes, an air inlet pipe, process reinforcement tubes, a liquid outlet pipe and bridging elbows. Each U-shaped pipe comprises two free ends extending in the same direction in parallel, and a bent part located between the two free ends, wherein the free ends are inserted in the corresponding fins. Ports of the free ends of every two adjacent U-shaped pipes are connected through the corresponding bridging elbow. The outdoor unit comprises a capillary tube, a compressor, an outdoor heat exchanger, the outdoor ultrasonic oscillators, a four-way valve, air-liquid separators, a filter and a check valve, wherein the outdoor ultrasonic oscillators are located around the outdoor heat exchanger. By means of the internal descaling and external defrosting novel air conditioner, ultrasonic non-stop on-line internal descaling and external defrosting can be achieved, the stable running environment of the air conditioner is ensured, and the service life is prolonged.

Description

technical field [0001] The invention specifically relates to a novel air conditioner using an ultrasonic oscillator for internal descaling and external defrosting, and belongs to the technical field of ultrasonic anti-scaling and defrosting. Background technique [0002] At present, there is no effective anti-scaling method in various production enterprises. The heat exchange equipment in the production process has different degrees of scaling problems. The scale thickness in most equipment production is between 0.2mm and 6mm. This phenomenon will cause energy consumption increased by more than 10%. [0003] Aiming at the fouling problem of heat exchangers, chemical or mechanical cleaning methods are mostly used at present; among them, the main disadvantage of chemical cleaning methods is that the chemical cleaning liquid is unstable, which will cause corrosion to the heat exchanger, and the discharge after cleaning will cause pollution; The cleaning method is to first take...

[0003] Aiming at the fouling problem of heat exchangers, chemical or mechanical cleaning methods are mostly used at present; among them, the main disadvantage of chemical cleaning methods is that the chemical cleaning liquid is unstable, which will cause corrosion to the heat exchanger, and the discharge after cleaning will cause pollution; The cleaning method is to first take out the U-shaped tube in the heat exchanger, immerse it in different liquids to soften and loosen the dirt, then remove the scale layer by mechanical means, and then put the cleaned U-shaped tube back into the heat exchanger On the downside of this method is the downtime required for descaling
