Four-season-type water-cooled dehumidification system and control method thereof

Abstract

The invention belongs to the field of dehumidification equipment, and provides a four-season-type water-cooled dehumidification system. The dehumidification system further comprises a heat exchangingdevice, an auxiliary condensing unit, a post-heating device, an air outlet fan and a system control device, wherein the heat exchanging device is connected with a refrigeration device so that air existing before entering an evaporator and air treated by the evaporator can be subjected to heat exchanging; the auxiliary condensing unit is arranged on an outlet channel of the heat exchanging device and further comprises an auxiliary condenser, and the auxiliary condenser is connected with a main condenser in series; the post-heating device is arranged behind the auxiliary condensing unit and usedfor heating the air flowing through; the air outlet fan is arranged at the outlet position of the dehumidification system and used for exhausting the air; and the system control device is used for controlling the system to operate according to the monitored temperature and humidity data. Compared with the prior art, by canceling a rotary dehumidification device and additionally arranging the heatexchanging device and the auxiliary condensing unit, electric power consumption of the system can be greatly reduced on the premise that the dehumidification requirements in the four-season environment are met, and good energy saving and emission reduction effects are achieved.

Description

technical field [0001] The invention belongs to the field of dehumidification equipment, in particular to a four-season water-cooled dehumidification system and a control method thereof. Background technique [0002] The four-season dehumidifier is one of the indispensable process equipment in the field of shipbuilding. Its function is to provide the necessary low humidity environment for the sandblasting (rust removal) and spraying (painting) processes of the shipyard. The so-called four-season dehumidifier is a dehumidifier that can provide dry air that meets the requirements of sandblasting and spraying in shipyards under various ambient temperature and humidity conditions throughout the year. [0003] Such as figure 1 As shown, the existing four-season dehumidifiers all use combined dehumidifiers. The dehumidification process consists of two parts: refrigeration dehumidification and runner dehumidification. Among them, refrigeration dehumidification is a large amount of...
