Problems solved by technology

The film type total heat exchanger has a layer of film between the two air streams, and uses the moisture permeability and heat transfer effect of this film to perform total heat exchange. Due to the heat and mass transfer mechanism, this total heat exchanger requires a High, so not widely used
However, the rotary wheel type total heat recovery device has a complex mechanism, high cost, and large pressure loss.
which limits its application to some extent
In addition, the common disadvantage of the air conditioners made of the above two kinds of total heat recovery devices is that during the heat exchange process, the two streams of air are mixed together, which not only consumes a lot of energy for air treatment, but also fails to meet the requirements of air purification. , detrimental to human health

Embodiment 1

[0014] see figure 1 , the fresh air air conditioner of the present invention comprises circulation pump 1, single-stage spray pump 3, condenser / evaporator 6, evaporator / condenser 8 and the five-stage (I-V) solution heat that is divided into upper and lower two layers and is evenly distributed by filler Recycler 5. Each solution heat recoverer 5 on the upper layer is sequentially connected with the indoor return air duct in series and then sent to the exhaust air duct. Each solution heat recoverer 5 on the lower floor is connected in series with the fresh air duct in the room in turn and then sent into the indoor air intake duct. The inlet of the circulation pump 1 is connected to the bottom of the lower V-level solution heat recovery device 5 near the outdoor fresh air duct, and the outlet of the circulation pump 1 is connected to the bottom of the upper V-level solution heat recovery device 5 near the exhaust duct. The bottoms of each solution heat recovery device 5 are seq...

Embodiment 2

[0019] see figure 2 , the parts of this embodiment that are the same as those of the foregoing embodiment will not be described again. The difference is that the heat exchanger 2 in the above-mentioned embodiment is removed, and the bottom end of the solution heat recovery device 5 in the lower layer formed with a difference of one level between the upper and lower layers is all connected to the inlet of the single-stage spray pump 3 provided at this stage. , the outlets of each single-stage spray pump 3 are sequentially connected to the spray pipes 7 in the upper solution heat recoverers 5 that are one level apart from the upper and lower levels, and the bottoms of the upper solution heat recovery units 5 are sequentially one level apart from the upper and lower levels The spray pipes 7 in each solution heat recovery device 5 of the lower floor are connected. The use process of this embodiment is also the same as that of the above embodiment, except that the heat exchange l...

Abstract

The present invention is fresh air air-conditioner with hot solvent recovering device, and belongs to the field of air conditioning technology. The multiple-stage hot solvent recovering device includes circulating pump, single stage showering pump, condensator, evaporator and stuffing. The present invention features that the multiple-stage hot solvent recovering device includes two, one upper and one lower, homogeneously distributed layers, the upper layer hot solvent recovering units are connected successively with the indoor return wind channel and exhaust channel, and the lower layer hot solvent recovering units are connected successively with the fresh wind channel and indoor wind channel. The circulating pump provides driving force for the flow of salt solution in the hot solvent recovering device, and the single stage showering pump provides required pressure head. The air dehumidifying process and the salt solution regeneration are completed in the two layers separately.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioner with a solution heat recovery device. Background technique [0002] Increasing the fresh air volume of the air conditioner can improve the indoor air quality, thereby creating a comfortable and healthy indoor environment, but increasing the fresh air volume is restricted by the energy consumption of fresh air processing. At present, the heat recovery method is mostly used in the field of air conditioning technology to recover the energy in the exhaust air to reduce the energy consumption of fresh air treatment. The heat recovery methods in the prior art mainly include total heat recovery and sensible heat recovery. Sensible heat recovery can only recover the sensible heat in the exhaust air, and the efficiency is low. Total heat recovery can recover both sensible heat and latent heat, with high efficiency. The current total heat recoverers mainly in...
