Cymbals are especially considered in the quality of service and operation of both economic considerations, not only to solve the problem of the preservation of cultural relics and humidity comfort in the storeroom and exhibition hall, but also to reduce energy consumption, energy conservation and environmental protection. Dehumidification system of the project warehouse, temperature control requirements: temperature 26±2℃, humidity requirements of 30%~60%. The dehumidification equipment adopts aluminum profile assembling form, the box panel adopts color steel plate and polyurethane foaming process, the specially designed structure details, the sealing property is excellent, to ensure to meet the production process requirements. The cold source of the equipment adopts the evaporation system, the heat source USES the condensation heat recovery, preheats the regenerative wind, and the distribution heating assists the heating, which can effectively reduce the operation energy consumption. The equipment adopts an economical and efficient way to deal with outdoor humid air, and can cooperate with the existing air conditioning system of the user to control the fresh air humidity within a certain range, and according to the indoor and outdoor humidity changes, automatic adjustment operation. The equipment installs part or all of the condenser of the refrigeration system in the regenerative heating air inlet part of the rotating wheel, which can recover the condensation heat generated in the refrigeration process and serve as the energy for regenerative wind heating, so as to truly reduce energy consumption and achieve the purpose of green environmental protection.
