Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a desktop air conditioner. Technical Background

[0002] Traditional compression air conditioners use a compressor to compress a low-temperature, low-pressure refrigerant into a high-temperature, high-pressure gas. The gas is then dissipated through a heat exchanger, cooling the refrigerant and turning it into a liquid that circulates between the indoor and outdoor units. This provides excellent cooling performance, but the high-power compressors used result in high energy consumption and noise levels. Regular maintenance, such as filter cleaning and fluorine replacement, is required during use, leading to high repair and replacement costs for the compressor and other equipment. Compared to traditional compressor-based refrigeration technology, semiconductor refrigeration technology offers less wear, less noise, and a smaller size. Because semiconductor refrigeration uses low-power cooling, it consumes less energy, is more environmentally friendly, and has low maintenance costs, making it more suitable for smaller spaces and energy-conscious environments. However, its drawbacks include low cooling capacity and poor cooling performance. Currently, there are few available desktop air conditioners, with complex designs, high costs, and limited adjustment functions. Products using semiconductor refrigeration technology often have poor structural design, resulting in poor cooling performance and inadequate cooling performance. Furthermore, existing air conditioners often suffer from dry indoor air during use, resulting in a poor overall user experience. Utility Model Content
