Embodiment Construction
[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0022] The principle and structure of the present invention will be described in detail below in conjunction with the drawings and embodiments.
[0023] It can be seen from the air temperature and humidity table that at the same air temperature, the greater the humidity, the higher the dew point temperature; at the same humidity, the higher the air temperature, the higher the dew point temperature. When the dew point temperature is lower than zero, frost will form when the dew point temperature is reached; when the dew point temperature is greater than zero, it wil...

The invention discloses a dehumidification device and system. The device comprises a first heat exchanger arranged on an air inlet flow pass, a second heat exchanger, a temperature and humidity sensorset, a valve assembly and a controller, wherein the second heat exchanger is arranged on an air outlet flow pass and communicates with the first heat exchanger through a pipe, the temperature and humidity sensor set monitors the air temperature and the air humidity of the air inlet flow pass, the valve assembly is arranged on the pipe to change the refrigerant flow direction of the first heat exchanger and the second heat exchanger, and the controller adjusts the valve assembly according to the air temperature and the air humidity so as to cool and condense wet air. According to the real-timetemperature and humidity, whether or not a four-way reversing valve is switched is judged, the flow direction of a refrigerant is changed, meanwhile, a throttling device is compared and adjusted according to the dew point temperature and the temperature of the second heat exchanger, the temperature of the surface of an evaporator is still within the wet air condensation temperature range, and thewet air is condensed on the surface of the evaporator and does not frost, so that water vapor in the environment is condensed on the evaporator all the time and does not frost, and therefore the dehumidification efficiency of a dehumidifier is greatly improved.
Description
technical field [0001] The invention relates to the technical field of dehumidification, in particular to a dehumidification device and a dehumidification system. Background technique [0002] At present, dehumidifiers on the market are mainly divided into household type, industrial type and other professional types, but no matter what type of dehumidifier it is, the market share of refrigeration principle dehumidifiers accounts for an absolute number. The key components of the refrigerated dehumidifier are two devices, namely the evaporator and the condenser, but the two devices of the refrigerated dehumidifier on the market today are very poor in low temperature environments, because the humid gas in the low temperature environment is evaporating. The frost on the surface of the compressor is more serious. A thicker frost layer will affect the air volume and heat exchange efficiency of the gas. Frequent shutdown of the compressor is required to defrost, which seriously aff...
