Description

Technical Field

[0001] The utility model relates to the technical field of heating, ventilation and air conditioning, and in particular to a hydraulic module of a constant temperature and humidity air preheating unit. Background Art

[0002] In many industrial production, scientific research, and environmentally demanding environments, strict requirements are placed on air temperature and humidity. A constant temperature and humidity environment ensures product quality, the accuracy of experimental results, and the proper functioning of equipment. To achieve this constant temperature and humidity control, an air preheater is a key component. It preheats the air, regulating its temperature and providing a stable foundation for subsequent humidity control steps.

[0003] Water seepage is a common problem in traditional water systems. Once this happens, it not only damages critical components like pumps, valves, and filters, but can also cause electrical short circuits, impacting the normal operation of the entire water system. Condensation occurs when the surface temperature of pipes and equipment in the water system falls below the dew point of the surrounding air. The condensed water produced by this condensation adheres to metal surfaces and causes corrosion. This corrosion not only reduces the lifespan of the equipment but can also lead to serious consequences such as pipe leaks and valve failure. Furthermore, traditional hydraulic modules without pipe heating systems are prone to freezing pipes in cold winters. When the water temperature drops below freezing, the water in the pipes freezes and expands, causing pipe ruptures or even the entire water system to fail.

[0004] Furthermore, traditional hydraulic modules lack dedicated cleaning devices inside the tank, so after prolonged use, dirt and sediment easily accumulate inside the tank. This dirt can come from impurities in the water source, rust from pipe corrosion, and the growth of microorganisms, posing serious health risks.

[0005] Based on this, the utility model designs a hydraulic module of a constant temperature and humidity air preheating unit to solve the above problems. Utility Model Content
