In the above technical solution, preferably, the pre-cooling and reheating section is a heat exchanger.
The utility model provides an above-mentioned constant temperature and humidity air treatment unit's main beneficial effect lies in:
the utility model discloses a set up hybrid tube and fresh air inlet to mix the new trend with the return air heat transfer of the section processing of reheating through the precooling, thereby realize reheating the air of cooling dehumidification, then handle the mist through the surface cooler, and again through the dehumidification pipe heat transfer, thereby can discharge the air that satisfies the air supply temperature demand from the supply-air outlet.
The outdoor fresh air is mixed with the return air for cooling and dehumidifying, so that the outdoor fresh air is used as a reheating heat source, a common reheating heat source is saved, and meanwhile, the temperature and enthalpy value of the outdoor fresh air after heat exchange are reduced, so that the heat load of the fresh air is reduced, and compared with the prior art in which the fresh air is heated through a heat source, the temperature is not required to be further adjusted, the energy utilization efficiency is improved, and the comfort level of a human body can be improved.
When outdoor temperature is lower, through setting up the electricity and assisting the heater, preheat the return air of cooling dehumidification and the air after mixing with the new trend through the electricity and assisting the heater, thereby effectively guarantee air supply temperature, simultaneously because the electricity is assisted the heater and need not directly heat the return air to air supply temperature, but through mixing the heat transfer with the new trend, with further heating, when the temperature that gets into the blast pipe does not reach the settlement temperature, the heating of resupply, therefore its energy consumption is also littleer for current structure, energy efficiency is also higher.
Through setting up governing valve and control tube, when outdoor temperature is higher, when the mixed gas heat transfer dehumidification back temperature still is higher than the settlement temperature through the precooling reheat section, the governing valve is opened to the accessible, makes the control tube further mix the lower cooling dehumidification's of temperature return air and the higher mixed gas of temperature to reduce the air supply temperature, thereby furthest utilizes gas self heat, furthest improves energy utilization efficiency.
