Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration machinery, in particular to a dehumidification and reheating cabinet unit with a hydraulic module. Background Art

[0002] Traditional water-cooled cabinet units for indoor cooling only come with a refrigerant module that meets their cooling needs. Before use, users must install a hydraulic module to match the unit's refrigerant module for safe and efficient operation. Designing and installing a hydraulic module that matches the unit's refrigerant module is relatively complex and specialized, and installation is often difficult due to site constraints. Furthermore, traditional water-cooled cabinet units for indoor cooling only control the room's temperature. To achieve optimal indoor temperature and humidity, electric auxiliary heating is required, which consumes a lot of power and is not energy-efficient or environmentally friendly. Furthermore, in traditional water-cooled cabinet units, the cooling water heats up after passing through the water-cooled condenser and must be dissipated through a cooling tower before it can continue to circulate, wasting both cooling tower power and the heat generated by the cooling water.
