Abstract

The invention relates to the technical field of air conditioner refrigerating and heating, in particular to an ultrasonic nanometer absorption type air conditioner unit. The ultrasonic nanometer absorption type air conditioner unit comprises a generator, a condenser and an evaporator. An absorber is arranged between the evaporator and the generator. An inlet in the upper end of the absorber communicates with an outlet in the lower end of the generator. The absorber communicates with a steam outlet of the evaporator. The outlet end in the lower end of the absorber is provided with a solution pump. The solution pump communicates with the solution inlet end of the generator through an outlet pipe. A cooling water pipe used for cooling a nanometer lithium bromide solution at the lower portion in the absorber penetrates in the absorber. Multiple ultrasonic generators are arranged in the absorber. Vibration heads of the ultrasonic generators face the nanometer lithium bromide solution in the absorber. The ultrasonic nanometer absorption type air conditioner unit is convenient to install and maintain, the nanometer lithium bromide solution is scattered through the ultrasonic generators, the heat transfer and mass transfer efficiency of the lithium bromide solution is improved, the energy exchange efficiency of an air conditioner system is improved, and extremely-large popularization value is achieved.

Description

technical field

[0001] The invention relates to the technical field of air-conditioning refrigeration and heat exchange, in particular to an ultrasonic nano-absorption air-conditioning unit. Background technique

[0002] At present, the known lithium bromide solution absorption refrigeration method uses water as a refrigerant and lithium bromide as an absorbent. Cooling is obtained by the evaporation of water. The lithium bromide absorption refrigeration device is mainly composed of generator, condenser, evaporator, absorber, heat exchanger, circulation pump and other parts. During the operation of the lithium bromide absorption refrigeration device, when the lithium bromide aqueous solution is heated in the generator, the water in the solution is continuously vaporized; with the continuous vaporization of the water, the concentration of the lithium bromide aqueous solution in the generator continues to increase and enters the absorber; Water vapor enters the condenser, is...

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as Figure 1~2 , an ultrasonic nano-absorption air-conditioning unit, comprising a generator 4, a condenser 5 whose inlet end communicates with the steam outlet end of the generator 4, an evaporator 7 whose inlet end communicates with the outlet end of the condenser 5, and inside the generator 4 A heating device is provided for dilute nano-lithium bromide solution (concentrated and dilute in this embodiment refers to lithium bromide solution, rather than the concentration of nanoparticles, and the heat transfer coefficient of nano-lithium bromide solution is larger than that of traditional lithium bromide solution, which is more conducive to heat transfer) for heating, the moisture in the heated nano-lithium bromide solution evaporates to form a concentrated nano-lithium bromide solution, and the evaporated water vapor ent...
