Refrigeration and heating double-effect air conditioner system using ultrasonic atomization technique

Abstract

A refrigerating-heating double-effect air conditioning system utilizing an ultrasonic atomizing technique comprises an indoor heat exchanger, an outdoor heat-exchanging fan, an outdoor heat exchanger, an outdoor heat exchanging fan, a first atomizer and a second atomizer which are provided with vacuum cavities filled with refrigerant, a medium-transferring assistant fan arranged in the first atomizer and ultrasonic transducers which are respectively arranged in the first and second atomizers. A heat exchanging coil of the outdoor heat exchanger is communicated with a heat exchanging coil of the second atomizer; the bottoms of the first and second atomizers are communicated through a backflow pump, and the level of the refrigerant inside the first and second atomizers is regulated a level-control backflow pump. When the ultrasonic atomization is carried out for the refrigerant in the first atomizer, the refrigerating can be realized; when the ultrasonic atomization is carried out for the refrigerant in the second atomizer the heating can be realized. The invention can displace the compressor mechanical refrigerating and lithium-bromide refrigerating, and the shifting between refrigerating and heating can be conveniently realized according to the requirements. The invention is suitable for the household air conditioners and central air conditioning systems and is characterized in that the energy can be conserved; the manufacturing cost is low; the operation cost is low; the service life is long and the efficiency is high.

[0002] Most of the existing household air conditioners use compressors to exchange the heat generated by evaporating and condensing the refrigerant Freon. They are mainly composed of compressors, evaporators and condensers. They have some disadvantages: the compressor is a mechanical structure and has a short lifespan. The noise is loud; the refrigerant freon seriously damages the ozone layer of the atmosphere, which is not conducive to environmental protection; the energy consumption is large and the use cost is high. If the general family uses the air conditioner in summer, they have to pay hundreds of electricity bills per month, which makes some economic conditions relatively low. Poor families don't want to use

[0003] Most of the existing central air conditioners are lithium bromide absorption type, which uses water as the refrigerant and lithium bromide as the absorbent absorption refrigeration technology to exchange heat. It is mainly composed of generators, condensers, evaporators and absorbers. Some disadvantages: power saving but high energy consumption, heavy weight, complex structure, and high cost; in the presence of air, lithium bromide solution is highly corrosive to ordinary carbon steel, which not only affects the life of the unit, but also affects the life of the unit. Performance and Uptime

In the existing patent literature, there have been some studies on the application of the ultrasonic atomization principle in air conditioners, such as the Chinese patent No. 200320109065.7, the utility model patent named "Ultrasonic atomization and evaporative condensation device for air conditioners", and the Chinese patent No. 200520126786.8, the utility model patent titled "Air Conditioner with Ultrasonic Atomization Device". Air-conditioning device" utility model patent, which solves the problem of air-drying in the air-conditioning room affecting health; another example is the utility model patent named "ultrasonic anti-scaling and anti-corrosion device for central air-conditioning", which solves the problem of central air-conditioning Anti-scaling and anti-corrosion problems of the water circulation system; another example is the Chinese patent No. 03144509, named "natural wind indirect evaporative cooling air handler and its application", and the Chinese patent No. 200710173263.2, named "Evaporative cooling air conditioner based on ultrasonic technology They all use the evaporative cooling and refrigeration realized by the ultrasonic atomization device, but the direct heat exchange between water and air has a dehumidification process, but it still cannot avoid the problem of excessive indoor humidity, and it is necessary to add water during use Maintenance is troublesome, and the evaporation of water under normal temperature and pressure is not ideal for cooling the air. In addition, the heating of the same components cannot be realized, so it cannot meet the needs of users in all seasons throughout the year
