Description

technical field [0001] The invention relates to an air source integrated drying and dehumidifying technology, in particular to a high-performance air source drying and dehumidifying integrated machine and system. Background technique [0002] Most of the current air-source drying and dehumidifiers adopt a straight-through structure to improve air volume and heating efficiency, and also have a certain thermal uniformity performance. However, in the current straight-through structure, the return air directly passes through the evaporator, Although the condenser has a large air volume, the utilization rate of waste heat and the stability and uniformity of heating are not enough, and the overall effect needs to be improved.

AI Technical Summary

Problems solved by technology

It discloses an air source integrated drying and dehumidifier and system, which adopts a straight-through structure, and the evaporator and condenser share the air duct to improve the air volume and heating efficiency, and also have a certain thermal uniformity performance, however , since the return air containing waste heat is directly dehumidified through the evaporator, it will inevitably lead to a lower dew point, and the evaporator needs a lower operating temperature, which is below 20°C. In this way, although the realization of a low dew point is helpful to increase the dehumidification capacity , but it will lead to large waste heat loss, low retention, affect the utilization rate of waste heat, and also lead to poor dehumidification stability, difficult to control the dehumidification amount and many other problems

In addition, a key problem of the traditional straight-through air source drying and dehumidifying machine is that the return air (the return air contains a lot of waste heat) has a relatively high retention after being directly dehumidified by the evaporator. When this temperature passes through the air duct of the all-in-one machine, due to the large temperature difference, it will generate a large heat loss again, which will affect the utilization rate of waste heat and affect the stability of temperature; For example, the manual attached to "A Drying and Dehumidifier and System with Integrated Air Source" figure 1 As shown in , the return air at 55°C, after being dehumidified by the evaporator (the operating temperature of the evaporator reaches 17°C below 20°C), becomes 46°C and enters the air duct, because 46°C is a relatively high temperature (largely higher than room temperature), and when this temperature passes through the air duct of the all-in-one machine, due to the large temperature difference, a large heat loss will be generated again, which will affect the utilization rate of waste heat and affect the stability of temperature

Therefore, there are still many unreasonable places in the traditional air source drying dehumidifier and system, which need to be improved and perfected.
