Abstract

The invention discloses a high-temperature type dehumidifier and a control method of the dehumidifier. According to the dehumidifier, a compressor, a second electromagnetic valve, a condenser and an evaporator are sequentially connected in series, a first electromagnetic valve and a reheat condenser are connected in series and then are connected with the second electromagnetic valve and the condenser in parallel, and a dehumidifying evaporator and a dehumidifying electromagnetic valve are connected in series and then are connected with the evaporator in parallel. The dehumidifier is flexible to control, wide in application range and simple in structure.

Description

technical field [0001] The invention relates to a dehumidifier, in particular to a high-temperature dehumidifier and a control method thereof. Background technique [0002] Conventional water-cooled dehumidifiers widely used at present are generally composed of compressors, water-cooled condensers, evaporators, expansion valves and their accessories. The water inlet temperature is 18~32℃. The performance of the unit is mainly limited by the condensing temperature. High water inlet temperature leads to high condensing temperature, which increases the discharge temperature of the compressor. Low water inlet temperature leads to low condensing temperature, which reduces the discharge pressure of the compressor. Without any protection measures When the above two conditions are severe, the compressor will be damaged. In addition, the heat exchange area of ​​the conventional water-cooled unit is fixed. At low temperature, when the humidity does not meet the requirements, the hum...
