The invention relates to a constant temperature dehumidification system, and provides a multifunctional constant temperature dehumidification system and a constant temperature dehumidification controlmethod, with the advantages of the simple structure, energy saving, environmental protection, and capability of automatic detecting and regulating the temperature and humidity of a controlled room. The technical problems of high investment cost, large occupied space, poor constant temperature and humidity effect and the like in the prior art are solved. The multifunctional constant temperature dehumidification system comprises a freezing type dehumidification system composed of an indoor unit and an outdoor unit, and the outdoor unit is connected to the indoor unit through an outer input endpipeline and an outer output pipeline; and an inner condenser is connected between the corresponding outer input end pipeline and the outer output pipeline in the indoor unit in parallel, and the input end of the inner condenser is connected to the outer input end pipeline through a second-stage four-way valve; a control system is used for automatically detecting the temperature and humidity of the controlled room and selecting the inner condenser or the outdoor unit to use through the second-stage four-way valve as well as changing the circulation direction of refrigerants for achieving the purposes of cooling dehumidification, constant temperature dehumidification or heating of the controlled room.
Description
technical field [0001] The invention relates to a constant temperature dehumidification system, in particular to a multifunctional constant temperature dehumidification system and a constant temperature dehumidification control method with simple structure, energy saving and environmental protection, which can automatically detect and adjust the temperature and humidity of a controlled room to keep the temperature and humidity of the controlled room constant. Background technique [0002] With the development of the modern economy, in many cases, it is necessary to have higher requirements on the environment of production, laboratory or storage, especially the treatment of constant temperature and humidity, and its application has gradually expanded. Therefore, a reasonable design of constant temperature and humidity solutions has become an environmental Points to build. The existing constant temperature and humidity method is generally to install dehumidifiers, humidifiers ...
