The invention provides a constant-temperature dehumidification system and a control method thereof. The control method comprises the steps: acquiring current first environmental humidity; when the first environmental humidity is greater than dehumidification entering humidity, acquiring current second environmental humidity; when the second environmental humidity is greater than dehumidification quitting humidity, continuously carrying out a constant-temperature dehumidification process until the current environmental humidity is smaller than the dehumidification quitting humidity. Under higher environmental humidity, the constant-temperature dehumidification system steps into control on constant-temperature dehumidification, so that a requirement on dehumidification can be met; meanwhile, the air discharging temperature is higher, so that the temperature of a component such as a panel and a tuyere cannot reach the dew point temperature of ambient air, gaseous water molecules in the environment cannot be condensed, and the possibility of condensation is avoided fundamentally; therefore the problem of condensation is solved, and the comfortableness of a human body is improved.
Description
technical field [0001] The invention relates to the technical field of automation, in particular to a constant temperature dehumidification system and a control method thereof. Background technique [0002] Condensation is a common natural phenomenon. There is a certain amount of gaseous water molecules in the air. When the gaseous water molecules come into contact with a lower temperature object, and the temperature is lower than the dew point temperature of the air, the gaseous water molecules in the air will It will be precipitated in liquid form and attached to the surface of the object to become water droplets. During the cooling process of the air conditioner, due to the low temperature of the air supply, it is easy to blow the air conditioner panels and air outlets cold. When the temperature is lower than the dew point temperature of the ambient air, more water droplets will accumulate on the panels and air outlets, forming condensation. [0003] When solving the pro...
