Embodiment Construction

[0007] Below in conjunction with accompanying drawing, technical scheme of the present invention is described further:

[0008] see figure 1 , The fresh air processor includes: gas-liquid direct contact modules A~G, plate heat exchanger 2, solution self-circulation pump 3, air valve 4, water pump 5 and other components. The fresh air fan is divided into upper and lower channels, the upper channel is the return air processing channel, and the lower layer is the fresh air processing channel. The upper channel is composed of gas-liquid direct contact modules A, B, C, and D, and the lower channel is composed of gas-liquid direct contact modules E, F, and G. The upper gas-liquid direct contact modules B, C, and D correspond to the lower modules E, F, and G respectively to form three-stage total heat recovery, and the upper and lower modules of each stage are connected by a plate heat exchanger 2 . Inside the modules B, C, and D, the return air is used for evaporative cooling to g...

Abstract

The invention relates to a recycle thermal-driving solution fan, which uses reflux air to vaporize and cool. Wherein, said invention comprises gas-liquid direct-contact modules (A-G), sheet heat exchanger, solution self-circulate pump, fan valve, and water pump; the upper channel is formed by the modules (A, B, C, D); the lower channel is formed the modules (E, F, G); the upper modules (B, C, D) is relative to the lower layer modules (E, F, G) to form three-stage heat recycles; each stage of upper and lower modules are connected by the sheet heat exchanger; the solution is cooled to be sprayed in the lower modules (E, F, G), to directly contact the air to dehumidify the air; and the dense solution enters into the lower modules (E, F, G); the upper module (A) contains the vaporizing cooling process between air and cold water, to generate cold water into the lower air cooler to reduce the temperature of air.

Description

technical field [0001] The invention relates to a heat-driven solution fresh air unit used in the field of heating, ventilating and air-conditioning, which uses return air to evaporate and cool the total heat recovery type, and belongs to the field of energy technology. Background technique [0002] The way of solution dehumidification treatment of air is the process of dehumidifying or humidifying the air by using the direct contact between the hygroscopic salt solution and the air, and using the difference between the water vapor partial pressure of the air and the surface vapor pressure of the salt solution. Compared with the condensation dehumidification method of the traditional system, the air treatment method of solution dehumidification does not require a low-temperature (7-12°C) cold source, which not only eliminates indoor wet surfaces, thereby improving indoor air quality, but also provides a variety of natural free air. The utilization of cold source creates cond...
